Purpose To describe a single-center 15-year experience of active surveillance (AS) for prostate cancer (PCa). Materials and Methods We retrospectively reviewed patients who underwent AS between 2003 and 2018. One hundred fifty-three patients were selected according to the following criteria: (1) biopsy Gleason pattern ≤3+4 with (2) ≤two positive core(s) and (3) ≤50% core involvement, clinical-stage ≤T2a, and prostate-specific antigen (PSA) ≤20 ng/mL. Follow-up included PSA measurement every six months, prostate biopsies at one year and then every 2–3 years, and MRI every year. Intervention was triggered by (1) Gleason score (GS) upgrading, (2) >two positive cores, or (3) PSA doubling-time in two positive cores (8.5%), abnormal PSA kinetics (11.9%), and patient preference (37.3%). Notably, 12 (25.5%) patients had pathologic GS ≥4+3 (unfavorable disease) and 3 (6.4%) patients had pathologic stage ≥T3a at radical prostatectomy. Median time to treatment-free survival was 19.5 months. Of the 59 patients who switched to intervention, biochemical recurrence was reported in only one (0.7%) patient. Conclusions AS is an available option for low-risk PCa in carefully selected patients. Further larger prospective studies are needed to determine the optimal criteria for AS, especially in Korean PCa patients., Graphical Abstract

OBJECTIVE To investigate the effectiveness of re-sleeve gastrectomy (LRSG) in patients who had insufficient weight loss or weight regain after laparoscopic sleeve gastrectomy (LSG). STUDY DESIGN Descriptive study. PLACE AND DURATION OF STUDY Ortadogu Private Hospital, Turkey, between March 2013 and January 2017. METHODOLOGY Patients who underwent LRSG following LSG due to inadequate weight loss or weight regain retrospectively evaluated. Patients' demographics, comorbidities, and bariatric surgery outcomes, as well as hospitalisation rate, excess weight loss percentage (EWL%), and body mass index (BMI ) were recorded. Scheduled follow-up visits after surgery at 1, 3, 6, and 12 months post-surgery and every six months subsequently were done. RESULTS A total of 21 patients that underwent LRSG after LRG due to inadequate weight loss or a regain in weight. Of them, 7 (33.3%) were males, and 14 (66.7%) were females. The mean body weight index (BMI) before primary LSG was 52.3 ±4.7 Kg/m² and EWL% was 32.7 ±4.6. After an average follow-up of 24 months. BMI of patients before LRSG was 46.1 ±4.3 Kg/m². Following a 1-year observation, there was a substantial (p

The relationships between depressive symptoms, viral suppression, and condomless sex were examined in a prospective cohort study of 369 HIV-positive Kenyan female sex workers. Participants were screened for depressive symptoms at baseline and every six months until completion of the study (up to 66 months). HIV viral load (VL) was measured every six months and prostate specific antigen (PSA) testing in vaginal secretions was performed quarterly. Mild or greater depressive symptoms were found in 100 (27.1%) women and were associated with increased risk of detectable VL (aRR 1.41, 95%CI 0.97–2.07, p-value = 0.07), but were not associated with detectable PSA. The co-occurrence of PSA detection and detectable VL at the same visit suggests the potential for HIV transmission but was uncommon (2.4% of visits). The prevalence of depressive symptoms and the association with detectable VL suggests the need for screening and treatment of depression for comprehensive HIV care in this population.

Unibody bifurcated endografts have the advantage of reducing the operative time, avoiding migration and iliac limb dislocation in patient with abdominal aortic aneurysm (AAA). We report our longterm experience in patients who underwent endovascular aortic repair (EVAR) due to infrarenal AAA with Endologix AFX (R) endograft system. Between January 2013-December 2018, 68 patients with infrarenal AAA had EVAR procedure with Endologix AFX (R) endograft system. Mean follow-up was 40.4 +/- 19.5 months, and all patients had computed tomography periodically, with colored Doppler ultra-sonography (CDUS) every six months. Mean age was 68.5 +/- 7.1 years and, 63 (92.6%) patients were male. Early mortality, renal complications, stent-graft migration and cardiac complications were not seen in early post-operative period. There was no early mortality in the group and no conversion to open repair. In long-term follow-up 12 patients (17.6%) had endoleak (5 with type II, 7 with type III). Overall survival estimated by Kaplan-Meier analysis was 94.1% at 1 year, 85.2% at 2 years, 74.1% at 3 years and 54.0% at 5 years. Freedom from second intervention and conversion was 98.4% at 1 year, 95.3% at 2 years, 93.3% at 3 years and 87.4% at 5 years. Endologix AFX (R) endo-graft provides a fast, safe and effective endograft for the early period, therefore it seems more suitable for elderly and comorbid patients. This endograft has low reintervention rates however according to our results, aneurysms larger than 6 cm may have more sideway displacement possibility and by this way type III endoleak. Proper patient selection and sufficient overlap are the key issues. Close monitoring is mandatory at the follow-up period. WOS:000672805600023 2-s2.0-85111065516 PubMed: 34258912

Objective The authors conducted a case series to determine arrest of root surface caries lesions in older adults when teeth were treated topically with 38 % silver diamine fluoride (SDF). Methods The study was a prospective, single center case series. The patients were 62 older adults (age ≥55 years) who sought treatment at a dental school clinic. To be included, a patient needed to have at least one active root caries lesion. Lesions were rinsed and then dried with air, isolated, and then 38 % SDF was applied for two minutes with a microbrush. Treated lesions were re-evaluated at 2–3 weeks. Treatment was repeated every six months. Survival analysis methods for clustered data were used to estimate the caries lesion arrest probability over time separately for root surfaces and at crown margins. Results Fifty-five participants returned for follow-up (44 % female, mean age (SD) 79.8 (7.4)). The probability of a lesion arresting with treatment ranged from 82.9 to 91.6%. Arrest rates at 18 months were slightly higher in root surfaces than around crown margins, 91.6 % (95 % CI 69.1–97.1) versus 89.8 % (95 % CI 71.6–96.3). All furcal lesions (n = 7) were arrested by 6 months, 100 % (95 % CI 59–100). Conclusion and Clinical Significance Repeated application of 38 % SDF at 6-month intervals was effective in arresting decay of root surface lesions and lesions around crowns in older adults. Study outcomes support SDF treatment for older adult patients who are frail and residing in nursing homes or dependent living facilities.

Intraventricular meningiomas (IVMs) are notably limited tumors and express one of the most challenging tumors in neurosurgery. Gamma Knife radiosurgery (GKRS) as an alternative for IVMs has been reported only in a few case series. We aimed to present six patients with IVMs who were treated with GKRS and do a literature review. The data of patients were retrospectively reviewed. All patients underwent a single session of GKRS with a median marginal dose of 12 Gy (range, 11–13). Target volume ranged from 1.2 to 9.5 cc. Routine imaging with contrast-enhanced MRI scans was performed every six months initially and thereafter yearly. New neurological deficits and symptoms stated or observed during follow-up were recorded and investigated. The mean age was 41.3 years (range, 30–71). GKRS was used as a primary treatment in five patients and as adjunctive treatment in one patient. The most common presenting symptom was a headache. The median duration of symptoms was 30 months (range, 5–240). Four tumors (67%) were located in the left lateral ventricle, and two were in the right lateral ventricle. During a median follow-up of 71.5 months (range, 23–139), tumor volume was noted to have shrunk (median = 59.6%) in all patients (100%). One patient experienced post-GKRS peritumoral edema that resolved after a short course of steroids. The mean progression-free survival was 117.5 months (95% CI, 81–154 months). Neurologic symptoms and signs improved in all patients. GKRS may be a feasible treatment alternative in patients with small IVMs with low morbidity.

Dental caries is the most prevalent oral disease in Ecuador. In our country, there are no studies that have included the population of the Galapagos Islands. Fluoride application to incipient lesions of dental caries has shown to be effective in avoiding the use of invasive restorative procedures.The objective of the EESO-Gal study is to determine the prevalence and incidence of dental caries and to evaluate the effect of supervised dental brushing, accompanied by periodic applications of fluoride varnish on incipient precarious lesions of schoolchildren in the Galapagos Islands. This article presents the protocol of the EESO-Gal study.A cohort is planned with Galapagos Islands schoolchildren to determine the prevalence and incidence of dental caries, with assessments every six months, during twenty-four months.We expect to determine the prevalence and incidence of caries every six months, for twenty-four months, in schoolchildren between three and ten years of age, and obtain data to show the state of the caries conditions in Galapagos schoolchildren, with the inclusion of daily brushing at school, supervised by the teacher, and with the application of fluoride varnish every six months.The prevalence of dental caries and incidence after the program will demonstrate the importance of implementing oral health prevention and promotion actions to create hygiene and health habits from an early age.La caries dental es la enfermedad bucal más prevalente en Ecuador. En nuestro país no existen estudios que hayan considerado a la población de las Islas Galápagos. La aplicación de flúor sobre lesiones incipientes de caries dental ha demostrado efectividad para evitar ejecutar procedimientos invasivos restauradores.El objetivo del Estudio de Salud Oral Galápagos, EESO-Gal, es determinar la prevalencia e incidencia de caries dental y evaluar el efecto de la acción del cepillado dental supervisado, acompañado de aplicaciones periódicas de flúor en barniz sobre lesiones cariosas incipientes en escolares de las Islas Galápagos. Con este informe se busca reportar el protocolo del Estudio de Salud Oral Galápagos.Se plantea realizar una cohorte con los escolares de las Islas Galápagos para determinar la prevalencia e incidencia de caries con evaluaciones cada seis meses durante veinticuatro meses.Se espera determinar la prevalencia e incidencia de caries cada seis meses durante veinticuatro meses en escolares de tres a diez años y obtener datos que permitan evidenciar el estado de las condiciones de caries en los escolares de Galápagos con la inclusión del cepillado diario en la escuela, supervisado por el docente, y con la aplicación semestral del barniz de flúor.La prevalencia de caries dental e incidencia después de las acciones tomadas demostrará la importancia de aplicar acciones de prevención y promoción de la salud oral, para crear hábitos de higiene y salud desde edades tempranas.

Introduction World Health Organization (WHO) guidelines have shifted over time to recommend earlier initiation of antiretroviral therapy (ART) and now encourage ART initiation on the day of HIV diagnosis, if possible. However, barriers to ART access may delay initiation in resource‐limited settings. We characterized temporal trends and other factors influencing the interval between HIV diagnosis and ART initiation among participants enrolled in a clinic‐based cohort across four African countries. Methods The African Cohort Study enrols adults engaged in care at 12 sites in Uganda, Kenya, Tanzania and Nigeria. Participants provide a medical history, complete a physical examination and undergo laboratory assessments every six months. Participants with recorded dates of HIV diagnosis were categorized by WHO guideline era (50 years at diagnosis was independently associated with shorter time to ART initiation as compared to 18 to 29 years (HR: 1.38; 95% CI: 1.19 to 1.61). Conclusions Consistent with changing guidelines, the interval between diagnosis and ART initiation has decreased over time. Still, many adults living with HIV initiated treatment with low CD4, highlighting the need to diagnose HIV earlier while improving access to immediate ART after diagnosis.

BackgroundTwo types of mentalisation-based treatment (MBT) have been developed and empirically evaluated for borderline personality disorder (BPD): day hospital MBT (MBT-DH) and intensive out-patient MBT (MBT-IOP). No trial has yet compared their efficacy.AimsTo compare the efficacy of MBT-DH and MBT-IOP 18 months after start of treatment. MBT-DH was hypothesised to be superior to MBT-IOP because of its higher treatment intensity.MethodIn a multicentre randomised controlled trial (Nederlands Trial Register: NTR2292) conducted at three sites in the Netherlands, patients with BPD were randomly assigned to MBT-DH (n = 70) or MBT-IOP (n = 44). The primary outcome was symptom severity (Brief Symptom Inventory). Secondary outcome measures included borderline symptomatology, personality functioning, interpersonal functioning, quality of life and self-harm. Patients were assessed every 6 months from baseline to 18 months after start of treatment. Data were analysed using multilevel modelling based on intention-to-treat principles.ResultsSignificant improvements were found on all outcome measures, with moderate to very large effect sizes for both groups. MBT-DH was not superior to MBT-IOP on the primary outcome measure, but MBT-DH showed a clear tendency towards superiority on secondary outcomes.ConclusionsAlthough MBT-DH was not superior to MBT-IOP on the primary outcome measure despite its greater treatment intensity, MBT-DH showed a tendency to be more effective on secondary outcomes, particularly in terms of relational functioning. Patients receiving MBT-DH and MBT-IOP, thus, seem to follow different trajectories of change, which may have important implications for clinical decision-making. Longer-term follow-up and cost-effectiveness considerations may ultimately determine the optimal intensity of specialised treatments such as MBT for patients with BPD.

Purpose To evaluate the effects of increased endogenous Antisecretory Factor (AF) synthesis using specially processed cereals (SPC) in a sample of patients with defined unilateral Meniere’s disease (MD), compared to the results of a treatment protocol of intravenous glycerol and dexamethasone. Materials and methods Twenty-six patients with unilateral MD were divided in 2 groups and treated with SPC and with intravenous glycerol and dexamethasone for 24 months. Audio-vestibular evaluation was performed before (T0) and every six months. The number of vertigo spells were evaluated before and after therapy and the Efficacy Index (EI) was calculated. Questionnaires for hearing loss, tinnitus and quality of life were administered. Results EI decreased in the SPC group after 18 (T18) (p = .0017) and 24 (T24) months of therapy (p = .0111). There was a significant reduction for tinnitus score in the SPC group at T24 (p = .0131). No significant differences were found between the two groups at T0 (p = .4723), while a significant difference was found at T24 (p = .0027). Quality of life showed a significant improvement in daily activities in the SPC group (p = .0033) compared to the infusion therapy group. No statistically significant changes in PTA thresholds were found in both groups between T0 and T24. Conclusion The preliminary results of our study show a significant reduction of vertigo spells and a positive effect on tinnitus severity and on quality of life in patients with unilateral MD treated with SPC and when compared to patients treated with intravenous glycerol and dexamethasone. No effects on hearing thresholds were noted in both groups.

Purpose To evaluate if baseline ADC from DWI sequences could predict response to treatment in patients with sacral chordoma not suitable for surgery treated with carbon ion radiotherapy (CIRT) alone compared with volume changes. Methods Fifty-nine patients with sacral chordoma not suitable for surgery underwent one cycle of CIRT alone and a minimum of 12-months follow-up. All patients underwent MRI before treatment (baseline), every three months in the first two years after treatment, and every six months afterwards. For each MRI, lesion volume was obtained and median, kurtosis, and skewness ADC were analyzed within the whole lesion volume. Volume changes between baseline and the last available follow-up were used to divide patients with partial response, progression of disease and stable disease (PR, PD, and SD). Results Ten patients were excluded since DWI sequences from baseline MRI were not available. ADC maps obtained from baseline DWI examinations of 50 lesions in the remaining 49 patients were considered. Seven lesions were categorized as PD, 30 PR, and 13 SD. PD showed significantly higher median ADC values at baseline (p = 0.003) compared with both PR and SD (1665vs1253vs1263 *10−6 mm²/s), and more negative skewness values (-0.26vs0.26vs0.08), although not significantly different (p = 0.16). Conclusions Preliminary results suggest that baseline ADC could predict response to treatment with CIRT, particularly to detect potential non-responder patients.

BACKGROUND: There is paucity of evidence regarding the optimal follow-up (FU) regimen for lung cancer. Consequently, FU is organized differently across countries. The Danish FU regimen has short FU intervals with a computed tomography (CT) scan of the chest and upper abdomen every three months in the early phase (first 2 years), then every six months in the late phase of FU (3rd, 5th year). Characterizing recurrences missed by the FU program in terms of site, tumor histology, department, and phase of FU, could improve the FU program.MATERIAL AND METHOD: A case-control study of curatively treated stage I lung cancer patients who attended the Danish FU-program and had recurrence identified through the follow-up program (controls, FU group) or outside FU program (cases, symptomatic group).RESULTS: Of 233 included patients with recurrence, the FU group constituted 85% (n = 197). Among the 15% (n = 36) in the symptomatic group, 53% had involvement of the central nervous system compared with 3% in the FU group. The unadjusted odds ratio (OR) for having an isolated brain recurrence (IBR) in the symptomatic group was 52.3 (95%CI: 15.1-181.4) as compared with the FU group. The OR for having a symptomatic recurrence in the early phase of FU was 2.5 (95%CI: 0.7-8.7) compared with the late phase.CONCLUSIONS: The FU program did not identify the majority of patients with IBR. Including cerebral imaging in the FU program may result in an earlier detection of brain metastases. These matters should be studied in a prospective setting.

To evaluate the effectiveness of the orthokeratology (OK) lens slowing myopic progression compared with no intervention in pediatric eyes METHODS: A retrospective review of medical records was performed on 45 monocular myopic subjects 7 to 13 years of age who were treated with monocular ortho-k lens and followed-up for more than 12 months. The monocular myopia in the subjects' eyes was -0.75 to -4.25 D (diopter), and near emmetropia in the contralateral and with-the-rule astigmatism no greater than -1.50 D. Axial elongation OU, reflecting the progression of myopia was measured at baseline using the same AL-Scan Optical Biometer and compared between the two eyes of each individual every six months for one year in all subjects and for two years in 9 subjects.After 12 months of lens wear, axial length had increased by 0.36 ± 0.23mm in the control eyes (P0.001) but showed far less change (+0.07 ± 0.21 mm) in the OK eyes (P = 0.038). The nine subjects followed-up for 2 years showed no axial length change (+0.16 ± 0.25 mm) in the OK eyes (P = 0.095) after 24 months and significant axial length growth (+0.38 ± 0.26 mm; P = 0.002) in the control eyes. Control eyes showed progressive axial length growth throughout the study compared with the one OK lens eye.Using a contralateral eye study design, which prevented the influence of potential confounding factors, Effectiveness of the OK lens was proved. Myopic progression within a subject was excellent compared with no intervention.

OBJECTIVE: We assessed mobility disability trajectories before death in a large sample of very old adults using two analytic approaches to determine how well they correspond. DESIGN: Decedent sample from the Health, Aging and Body Composition Study (Health ABC). Data were collected between 1997 and 2015. SETTING: A population-based sample of 3075 participants, randomly selected from well-functioning White Medicare beneficiaries and all African American community residents meeting age criteria (70–79 years) in Pittsburgh, PA, and Memphis, TN. PARTICIPANTS: Of the 1991 participants who died by the end of the study, 1410 were interviewed for three years prior to death, including an interview six months before dying. EXPOSURES: Participants were interviewed in person or by phone at least every six months throughout the study. MEASUREMENTS: We analyzed self-reported mobility collected prospectively at six month intervals during the last three years of life. We derived trajectories in two ways: first by averaging decline within decedent groups pre-specified by clinical conditions and, second, by estimating trajectory models using maximum-likelihood semiparametric modeling. RESULTS: Classification by clinical conditions (sudden death, terminal, organ failure and frailty) accounted for 98% of decedents and produced groups with different characteristics. Five disability trajectories were identified: late decline, progressive disability, moderate disability, early decline, and persistent disability. Disability trajectory and clinical condition grouping both confirmed previous research but were only marginally related. CONCLUSIONS: Derived disability trajectories and grouping by clinical conditions both provide useful information about different facets of the end-of-life experience. The lack of fit between them suggests a need for greater attention to heterogeneity in disability in the period before death.

Introduction A family-centered care model (FCCM) providing family-based HIV services, rather than separate adult/pediatric services, has been proposed to increase pediatric retention and treatment adherence. Materials and methods Eight health-care facilities in the Hhohho region of Eswatini were randomized to implement FCCM (n = 4) or continue standard-of-care (SOC) separate adult/pediatric clinics (n = 4). HIV-positive children and caregivers were enrolled; caregiver interview and child/caregiver chart abstraction were done at enrollment and every three months; pediatric viral load was evaluated at enrollment and every six months through 12 months. Because of study group differences in 12-month viral load data availability (89.4% FCCM and 72.0% SOC children had 12-month viral load), we used three separate analyses to evaluate the effects of FCCM on children’s viral suppression ( Results We enrolled 379 HIV-positive children and 363 caregivers. Among all children at enrollment, viral suppression and undetectability was 78.4% and 73.9%, respectively, improving to 90.2% and 87.3% at 12 months. In mITT and weighted mITT analyses, there was no significant difference in children’s 12-month viral suppression between FCCM and SOC groups (89.2% and 91.6%, respectively). Using imputed ITT, there was a modest increase in 12-month viral suppression in FCCM versus SOC children (79.7% and 69.8%, respectively, p = 0.051) and 12-month undetectability (78.7% and 65.7%, respectively, p = 0.015). Among the 255 children suppressed at enrollment, more FCCM versus SOC children (98.0% versus 95.3%) were suppressed at 12-months, but this was not statistically significant in mITT or weighted mITT analyses, with a marginally significant difference using imputed mITT analysis (p = 0.042). A higher proportion of children suppressed at enrollment had undetectable viral load at 12 months in FCCM versus SOC children (98.0% versus 92.5%), a statistically significant difference across analytical methods. Among the 61 children unsuppressed at enrollment, achieving suppression was higher among SOC versus FCCM children, but this difference was not statistically significant and included only 38 children; and there were no significant differences in detectable viral load at 12 months. There were no significant differences between study groups in retention or ART adherence at 12 months for children or caregivers. Factors associated with lack of viral suppression/detectability at 12 months included lack of viral suppression at enrollment and having a younger caregiver (age Conclusions FCCM in Eswatini was associated with a modest increase in viral suppression/undetectability at 12-months; 12-month retention and adherence did not differ by study group for children or caregivers. High levels of suppression and retention in both groups may have limited our ability to detect a difference. Trial registration NCT03397420; ClinicalTrials.gov.

A negative sentinel lymph node biopsy (SLNB) for stage IB (T1b/T2a N0) melanoma would predict an excellent long-term prognosis. Combined with the concept of conditional survival, an “abbreviated” cancer surveillance strategy was implemented to reduce the number of visits and total length of follow-up. Retrospective review of all pathologic stage IB melanoma patients (negative SLNB) at a single institution between 2006 and 2008 after implementation of an “abbreviated” cancer surveillance; clinic visits every six months for five years followed by one annual visit (total follow-up six years). Patient demographics, tumor characteristics, and information regarding recurrences were obtained. Recurrence-free, disease-specific, and overall survival were calculated. Eighty-seven patients underwent the “abbreviated” cancer surveillance. Median age was 55.4 years and 50.6 per cent were male. Median Breslow thickness was 1.1 mm (range 0.5–2.0 mm) and 1.1 per cent were ulcerated. Primary tumor site was 49 per cent extremities, 39 per cent trunk, and 12 per cent head/ neck. Median follow-up was 68.6 months. Five-year recurrence-free, disease-specific, and overall survivals were 89, 95, and 88 per cent, respectively. During surveillance, 10 patients had concerning symptoms or physical findings prompting subsequent workup, all of which were negative for recurrence/metastases. There were only three true melanoma recurrences; all were distant metastases and presented symptomatically between scheduled follow-up visits. In light of the excellent prognosis for pathologic (SLNB negative) stage IB melanoma, an “abbreviated” cancer surveillance schedule based on conditional survival would reduce both direct and indirect costs in this cohort. The few recurrences were symptomatic and unlikely to have changed with more intensive surveillance.

Studies on the effects of alcohol use on HIV disease progression have been contradictory, with at least one study finding a positive effect of low alcohol consumption on CD4 count. In addition, most such studies have taken place in the developed West. We investigated the association between alcohol use and immune reconstitution through CD4 count response among HIV-infected individuals on antiretroviral therapy (ART) at an urban sub-Saharan African clinic. This was a retrospective cohort study of treatment-naïve HIV-infected adults initiating ART in Nairobi, Kenya and followed for 12 months between January 2009 and December 2012. At enrollment, a standardized questionnaire was used to collect data on sociodemographic variables and alcohol consumption. CD4 count was measured every six months. Linear regression models assessed the association between CD4 count and alcohol consumption, categorized as abstinent, moderate, or hazardous. Overall, 854 participants were included, 522 of which were women, with 85 (25.6%) men and 50 (9.6%) women reporting any alcohol use, and 8 (2.4%) men and 7 (1.3%) women reporting hazardous drinking. At baseline, alcohol use was associated with higher education and socioeconomic status. Median CD4 count was higher among alcohol users compared to those who abstained at baseline and at 6 and 12 months post-ART initiation, although this was only significant at 6 months. There were no differences in adherence between abstainers and drinkers. While overall alcohol use was significantly associated with higher CD4 counts, moderate and hazardous use treated separately were not. We conclude that, while alcohol use was associated with higher CD4 counts at 12 months post-ART, the mechanism for this association is unclear but may reflect unmeasured socioeconomic or nutritional differences. Additional research is required on the specific drinking patterns of this population and the types of alcoholic beverages consumed to clarify this relationship.

Pupillary light reflex (PLR) is an involuntary response where the pupil size changes with luminance. Studies have shown that PLR response was altered in children with autism spectrum disorders (ASDs) and other neurological disorders. However, PLR in infants and toddlers is still understudied. We conducted a longitudinal study to investigate PLR in children of 6–24 months using a remote pupillography device. The participants are categorized into two groups. The ‘high risk’ (HR) group includes children with one or more siblings diagnosed with ASDs; whereas the ‘low risk’ (LR) group includes children without an ASD diagnosis in the family history. The participants’ PLR was measured every six months until the age of 24 months. The results indicated a significant age effect in multiple PLR parameters including resting pupil radius, minimal pupil radius, relative constriction, latency, and response time. In addition, the HR group had a significantly larger resting and minimal pupil size than the LR group. The experimental data acquired in this study revealed not only general age-related PLR changes in infants and toddlers, but also different PLRs in children with a higher risk of ASD.

Multiple sclerosis (MS) is an immune-mediated disease of the central nervous system. Its treatment has focused on inflammation control as early as possible to avoid disability. Autologous hematopoietic stem cell transplantation (AHSCT) has been used for treating MS since 1996, with recent decisive results regarding benefits in long-term efficacy. Five patients followed up at an MS center in Belo Horizonte, Brazil, who had relapsing-remitting MS with high disease activity, underwent AHSCT between 2009 and 2011. They were evaluated clinically, with magnetic resonance imaging, and by the EDSS every six months after transplantation, up to July 2018. The patients were four women and one man, with ages ranging from 25-50 years, and time since disease onset ranging from 4-17 years at the time of the procedure. Four patients improved, one patient was stabilized, and all patients were free of disease activity after 5-9 years. Through improving patient selection and decreasing the time from disease onset, AHSCT could stop epitope spreading and disease progression. Despite multiple other therapeutic choices being approved for relapsing-remitting MS, AHSCT continues to be a treatment to consider for aggressive MS disease. RESUMO A esclerose múltipla é uma doença imunomediada do sistema nervoso central. Seu tratamento tem sido focado no controle da inflamação o mais cedo possível para evitar incapacidade. O transplante autólogo de células tronco hematopoiéticas (TACTH) vem sendo usado para tratar esclerose múltipla desde 1996, e recentes resultados foram decisivos a respeito do benefício na eficácia a longo prazo. Cinco pacientes seguidos num centro de esclerose múltipla de Belo Horizonte, Brasil, que apresentavam forma clínica remitente recorrente com alta atividade de doença foram submetidos a esse tratamento de 2009 a 2011. Após o transplante foram avaliados clinicamente e com ressonância magnética, e escala de EDSS, a cada seis meses até julho de 2018. Os pacientes eram quatro mulheres e um homem, com idade entre 25 e 50 anos e tempo de doença variando de 4 a 17 anos na época do procedimento. Quatro pacientes melhoraram após a primeira avaliação e um manteve-se estável. Todos os pacientes permaneceram sem evidência de doença clínica ou radiológica de 5 a 9 anos após. Com uma seleção cada vez mais criteriosa de pacientes o TACTH pode interromper a disseminação do epítopo e controlar a progressão da doença. Apesar de várias outras opções terapêuticas aprovadas para esclerose múltipla o TACTH continua a ser uma forma de tratamento a ser considerada em casos de doença muito agressiva.

Introduction HIV viral load (VL) testing is recommended by the WHO as the preferred method for monitoring patients on antiretroviral therapy (ART). However, evidence that routine VL (RVL) monitoring improves clinical outcomes is lacking. Methods We conducted a prospective, randomized controlled trial of RVL monitoring every six months versus a targeted VL (TVL) strategy (routine CD4 plus VL testing if clinical or immunological failure) in patients starting ART between April 2011 and April 2014 at Bach Mai Hospital in Hanoi. Six hundred and forty‐seven subjects were randomized to RVL (n = 305) or TVL monitoring (n = 342) and followed up for three years. Primary endpoints were death or WHO clinical Stage 4 events between six and thirty‐six months of ART and rate of virological suppression at three years. Results Overall, 37.1% of subjects were female, median age was 33.4 years (IQR: 29.5 to 38.6), and 47% had a CD4 count ≤100 cells/mm3 at time of ART initiation. Approximately 44% of study events (death, LTFU, withdrawal, or Stage 4 event) and 68% of deaths occurred within the first six months of ART. Among patients on ART at six months, death or Stage 4 event occurred in 3.6% of RVL and 3.9% of TVL (p = 0.823). Survival analysis showed no significant difference between the groups (p = 0.825). Viral suppression at 36 months of ART was 97.2% in RVL and 98.9% in TVL (p = 0.206) at a threshold of 400 copies/mL and was 98.0% in RVL and 98.9% in TVL (p = 0.488) at 1000 copies/mL. In ITT analysis, 20.7% in RVL and 21.9% in TVL (p = 0.693) were unsuppressed at 1000 copies/mL. Conclusions We found no significant difference in rates of death or Stage 4 events and virological failure in patients with RVL monitoring compared to those monitored with a TVL strategy after three years of follow‐up. Viral suppression rates were high overall and there were few study events among patients alive and on ART after six months, limiting the study's power to detect a difference among study arms. Nonetheless, these data suggest that the choice of VL monitoring strategy may have less impact on patient outcomes compared to efforts to reduce early mortality and improve ART retention.

OBJECTIVE: To assess the effectiveness of a school and family based healthy lifestyle programme (WAVES intervention) compared with usual practice, in preventing childhood obesity.DESIGN: Cluster randomised controlled trial.SETTING: UK primary schools from the West Midlands.PARTICIPANTS: 200 schools were randomly selected from all state run primary schools within 35 miles of the study centre (n=980), oversampling those with high minority ethnic populations. These schools were randomly ordered and sequentially invited to participate. 144 eligible schools were approached to achieve the target recruitment of 54 schools. After baseline measurements 1467 year 1 pupils aged 5 and 6 years (control: 28 schools, 778 pupils) were randomised, using a blocked balancing algorithm. 53 schools remained in the trial and data on 1287 (87.7%) and 1169 (79.7%) pupils were available at first follow-up (15 month) and second follow-up (30 month), respectively.INTERVENTIONS: The 12 month intervention encouraged healthy eating and physical activity, including a daily additional 30 minute school time physical activity opportunity, a six week interactive skill based programme in conjunction with Aston Villa football club, signposting of local family physical activity opportunities through mail-outs every six months, and termly school led family workshops on healthy cooking skills.MAIN OUTCOME MEASURES: The protocol defined primary outcomes, assessed blind to allocation, were between arm difference in body mass index (BMI) z score at 15 and 30 months. Secondary outcomes were further anthropometric, dietary, physical activity, and psychological measurements, and difference in BMI z score at 39 months in a subset.RESULTS: Data for primary outcome analyses were: baseline, 54 schools: 1392 pupils (732 controls); first follow-up (15 months post-baseline), 53 schools: 1249 pupils (675 controls); second follow-up (30 months post-baseline), 53 schools: 1145 pupils (621 controls). The mean BMI z score was non-significantly lower in the intervention arm compared with the control arm at 15 months (mean difference -0.075 (95% confidence interval -0.183 to 0.033, P=0.18) in the baseline adjusted models. At 30 months the mean difference was -0.027 (-0.137 to 0.083, P=0.63). There was no statistically significant difference between groups for other anthropometric, dietary, physical activity, or psychological measurements (including assessment of harm).CONCLUSIONS: The primary analyses suggest that this experiential focused intervention had no statistically significant effect on BMI z score or on preventing childhood obesity. Schools are unlikely to impact on the childhood obesity epidemic by incorporating such interventions without wider support across multiple sectors and environments.TRIAL REGISTRATION: Current Controlled Trials ISRCTN97000586.

Background Idiopathic pulmonary fibrosis (IPF) is a chronic disease with a high symptom burden and poor survival that influences patients’ health-related quality of life (HRQOL). We aimed to evaluate IPF patients’ symptoms and HRQOL in a well-documented clinical cohort during their last two years of life. Methods In April 2015, we sent the Modified Medical Research Council Dyspnea Scale (MMRC), the modified Edmonton Symptom Assessment Scale (ESAS) and a self-rating HRQOL questionnaire (RAND-36) to 300 IPF patients, of which 247 (82%) responded. Thereafter, follow-up questionnaires were sent every six months for two years. Results Ninety-two patients died by August 2017. Among these patients, HRQOL was found to be considerably low already two years before death. The most prominent declines in HRQOL occurred in physical function, vitality, emotional role and social functioning (p

Context HIV-related fatigue remains the most frequent complaint of seropositive patients. Objectives To describe the natural course of fatigue in HIV infection, in a sample ( n =128) followed for a three-year period. Methods A longitudinal prospective design was used to determine what factors influenced changes in fatigue intensity and fatigue-related impairment of functioning in a community-dwelling sample of HIV-infected individuals. Participants were followed every six months for a three-year period. At each study visit, we collected data on a large number of physiological and psychosocial markers that have been shown to be related to fatigue in HIV-infected people. At three month intervals between study visits, we collected data on fatigue via mailed questionnaires. Results Fatigue in HIV infection is largely a result of stressful life events, and is closely tied to the anxiety and depression that accompany such events. Fatigue did not remit spontaneously over the course of the study, indicating the need for interventions to ameliorate this debilitating symptom. Conclusion Intervening to help people who are suffering from HIV-related fatigue to deal with stressful life events may help to ameliorate this debilitating symptom.

Purpose. We studied the prognostic significance of Magnetic Resonance Spectroscopy (MRS) in operated high grade gliomas.Materials and Methods. Twelve patients were treated with radiotherapy and Temozolomide. The MRS data were taken four weeks after operation (before radiotherapy) and every six months after the completion of RT. The N-acetyl aspartate, choline, creatine, and myo-inositol parameters were quantified, analyzed, and correlated to recurrence-free survival (RFS).Results. The median RFS was 26.06 months. RFS was significantly worse in elderly patients(P=0.001)along with the higher choline/creatine ratios at either baseline(P= 0.003)or six months post Radiotherapy(P=0.042). Median RFS was 23 months in high choline/creatine levels ≥2 at 6 months after radiotherapy and 11 months for those with P=0.045).Conclusion. Age and choline/creatine ratio are strong independent prognostic factors in high grade gliomas.

Summary The United States Air Force HIV programme has several features that may enhance antiretroviral therapy outcomes, including free access to healthcare and mandatory clinical visits every six months at a single centre. We evaluated viral load suppression (90% of patients.

Current tools for measuring medication adherence have significant limitations, especially among pediatric populations. We conducted a prospective observational study to assess the use of antiretroviral (ARV) drug levels in hair for evaluating antiretroviral therapy (ART) adherence among HIV-infected children in rural Uganda. Three-day caregiver recall, 30-day visual analog scale (VAS), Medication Event Monitoring System (MEMS), and unannounced pill counts and liquid formulation weights (UPC) were collected monthly over a one-year period. Hair samples were collected quarterly and analyzed for nevirapine (NVP) levels, and plasma HIV RNA levels were collected every six months. Among children with at least one hair sample collected, we used univariable random intercept linear regression models to compare log transformed NVP concentrations with each adherence measure, and the child's age, sex, and CD4 count percentage (CD4%). One hundred and twenty-one children aged 2-10 years were enrolled in the study; 74 (61%) provided at least one hair sample, and the mean number of hair samples collected per child was 1.9 (standard deviation [SD] 1.0). Three-day caregiver recall, VAS, and MEMS were found to be positively associated with increasing NVP concentration in hair, although associations were not statistically significant. UPC was found to have a nonsignificant negative association with increasing hair NVP concentration. In conclusion, NVP drug concentrations in hair were found to have nonsignificant, although generally positive, associations with other adherence measures in a cohort of HIV-infected children in Uganda. Hair collection in this population proved challenging, suggesting the need for community education and buy-in with the introduction of novel methodologies.

The success of antiretroviral therapy (ART) as treatment for the individual patient and as prevention requires the achievment and maintenance of human immunodeficiency virus (HIV) viral suppression. Linkage to and retention in care are required for access to ART. We describe the impact of care on viral suppression using routinely reported surveillance data. We included New York City residents ≥13 years of age, diagnosed with HIV/AIDS from 1 July 2005 to 30 June 2009 with a viral load (VL) or CD4 reported within six months of diagnosis and ≥1 VL reported from 1 July 2005 to 30 June 2011. To examine viral rebound, we restricted the analysis to those who achieved viral suppression and had a subsequent VL measure reported by 30 June 2011. Cox proportional hazards models were used to evaluate factors associated with time to viral suppression (VL ≤ 400 copies/mL) and rebound (VL > 1000 copies/mL). Initiation of care within three months of diagnosis (CD4/VL report within three months of diagnosis), female sex, and an initial CD4 < 350 (cells/mm(3)) at diagnosis significantly increased the likelihood of viral suppression. Irregular care (no CD4/VL reported every six months), younger age, non-white race/ethnicity, having an initial CD4 ≥ 350 at diagnosis, and AIDS diagnosis by 2010 increased the likelihood of rebound. These findings lend support to interventions for improving linkage to and maintenance in regular care as a way to achieve and maintain suppression. Surveillance data represent an ideal means for monitoring engagement in care and viral suppression at the population level.

WOS: 000343956500017, PubMed ID: 25022224, Aims: To evaluate the safety and efficacy of the new Cera septal occluder (CSO) for atrial septal defect (ASD) closure as compared to the AMPLATZER Septal Occluder (ASO). Methods and results: A total of 405 ASD patients receiving CSO or ASO were studied. The ASDs were classified into simple defects (isolated defects 26 mm, large defects with a deficient rim, double or multi-fenestrated defects). Clinical and echocardiographic findings were collected before discharge, at one month, and every six months after implantation. Two hundred and five (133 females, aged 30 +/- 13 years) and 200 (135 females, aged 28 +/- 14 years) patients received CSO and ASO implants, respectively. The CSO group had similar ASD and device sizes, prevalence of complex lesions, procedural times and success rates as compared to the ASO group. Echocardiographic follow-up at one and six months showed similar residual shunts between devices. Both groups had similar rates for device embolisation and atrial arrhythmia. The average equipment cost per patient was lower in the CSO group than in the ASO group (US$3,500 vs. US$5,600, p

To evaluate the five-year stability of frontalis suspension of the upper eyelid with a silicone band for the treatment of severe congenital ptosis in infants.Chart review of pediatric patients with a follow-up of five years after unilateral frontalis suspension with silicone band was reviewed. Margin-reflex distance (MRD) and corneal staining were measured at different follow-up visits. Data were analyzed by analysis of variance and t test for paired data.Twenty pediatric patients were included in this retrospective study. MRD was severely reduced before surgery in all cases: it ranged from -1 mm to -4 mm (-2.4 ± 0.8 mm). After surgery, MRD increased to 2.9 ± 0.3 mm, and then progressively decreased by 0.6 mm within the first three months (p 0.001); a further reduction of 0.2 mm, occurring between three and 12 months after surgery, was not statistically significant (p 0.001). Between the 12-month and the five-year follow-up visits (one visit every six months), no changes in MRD were found for any patient. After the five-years visit, no substantial changes were recorded in 18 patients (90%); in two patients, a second surgery to improve the deterioration was necessary. Corneal staining, which was present in five patients (25%) during the first two postoperative weeks, disappeared over five years of follow-up.During the five-year follow-up of this retrospective study, the frontalis suspension with a silicone band proved to be a stable procedure. After 30 months from the first observation, MRD values were stable, except for two patients that underwent a second surgery to stabilize the worsening ptosis.

Objectives The aims of this study were to document the trajectory of weight gain and body mass index (BMI) in children with type 1 narcolepsy, and to analyze basal metabolic rate (BMR). Methods A total of 65 Chinese children with type 1 narcolepsy with a disease duration ≤12 months were included. In addition, 79 healthy age-matched students were enrolled as controls. Height and body weight were measured every six months for up to 36 months to calculate BMI growth. BMR was measured using COSMED K4b2 indirect calorimetry in 34 patients and 30 healthy controls at six months. At the end of 36 months, the BMR was compared among 18 patients and 16 healthy controls. Results The children with type 1 narcolepsy showed higher BMIs at follow-up assessments. At the end of the study, 38.46% of the patients were obese and an additional 26.15% were overweight. The patients' BMI growth at six, 12, 18, 24 and 30 months of follow-up was significantly higher, but not at month 36. The patients' basal energy expenditure was significantly lower than that of the controls at six months but not at 36 months. Conclusion BMI increased rapidly in children with type 1 narcolepsy after disease onset, but BMI growth decreased gradually with prolonged disease. Decreased BMR is an important cause underlying rapid weight gain. The gradual restoration of BMI growth and BMR in narcolepsy emphasizes the importance of compensatory metabolic mechanisms in this disease.

Objective To assess the evolution of brain atrophy and its relationship with inflammatory activity in RRMS patients treated with natalizumab. Methods Eighteen RRMS patients were prospectively followed up for 18 months after starting natalizumab therapy. Patients were monitored monthly and assessed for signs of relapses, adverse events or disability increase. MRI scans were performed before starting natalizumab and every six months. Cross-sectional T2 lesion volume (T2LV) and the normalized brain volume (NBV) at baseline and 18 months MRI scans were calculated using the Steronauta® and SIENAx softwares, respectively. Longitudinal Percentage of Brain Volume Change (PBVC) was estimated with SIENA. Linkage between inflammatory activity and brain atrophy was studied. Results Natalizumab reduced ARR by 67% and cumulative CEL by 87.5%. T2 lesion volume decreased from 1000 mm3, to 960 mm3 (p = 0.006) and NBV decreased from 1.55 × 105 mm3 to 1.42 × 105 mm3 (p = 0.025). Global PBVC from baseline to 18 months was −2.5%, predominantly during the first six months (0–6 months PBVC −1.7%; 6–12 months PBVC −0.74%; 12–18 months PBVC −0.50%). The number of relapses before treatment was correlated to the PBVC during the first semester (Pearson's coefficient −0.520, p = 0.003), while the number of basal CEL or baseline T2LV did not correlate with brain atrophy rate. During follow-up, nine patients had clinical or radiological inflammatory activity. Their PBVC was significantly higher in the first semester (−2.3% to −1.1%, p = 0.002). Conclusions Natalizumab reduced relapse rate and CEL in MRI. Brain atrophy predominated in the first semester and was related to previous inflammatory activity.

a b s t r a c t Objective: To compare the effectiveness of annual topical application of silver diamine fluoride (SDF) solution, semi-annual topical application of SDF solution, and annual application of a flowable high fluoride-releasing glass ionomer in arresting active dentine caries in primary teeth. Methods: A total of 212 children, aged 3‐4 years, were randomly allocated to one of three groups for treatment of carious dentine cavities in their primary teeth: Gp1-annual application of SDF, Gp2-semi-annual application of SDF, and Gp3-annual application of glass ionomer. Follow-up examinations were carried out every six months to assess whether the treated caries lesions had become arrested. Results: After 24 months, 181 (85%) children remained in the study. The caries arrest rates were 79%, 91% and 82% for Gp1, Gp2 and Gp3, respectively ( p = 0.007). In the logistic regression model using GEE to adjust for clustering effect, higher caries arrest rates were found in lesions treated in Gp2 (OR = 2.98, p = 0.007), those in anterior teeth (OR = 5.55, p < 0.001), and those in buccal/lingual smooth surfaces (OR = 15.6, p = 0.004). Conclusion: Annual application of either SDF solution or high fluoride-releasing glass ionomer can arrest active dentine caries. Increasing the frequency of application to every 6 months can increase the caries arrest rate of SDF application. Clinical significance: Arrest of active dentine caries in primary teeth by topical application of SDF solution can be enhanced by increasing the frequency of application from annually to every 6 months, whereas annual paint-on of a flowable glass ionomer can also arrest active

Objective To report our experience of laparoscopic radiofrequency ablation (RFA) on patients with renal tumors. RFA has been increasingly applied in the management of small renal tumors. However, it was performed mostly via percutaneous approach, with limited cases and a short follow-up period. Methods From February 2006 to March 2008, laparoscopic RFA was performed on 106 renal tumors (size range: 0.9-5.5 cm) in 106 selected patients (74 men and 32 women, age range: 25-81 years). Initial contrast-enhanced computed tomography (CT) examination was performed seven days after the procedure, with subsequent CT assessment at three months, six months, and every six months thereafter. Serum creatinine measurement was conducted along with each time CT examination. Results The mean follow-up period was 32 months (range: 12-48). All 106 tumors were biopsied before RFA, of which 90 were diagnosed as renal cell carcinoma (RCC) (84.90%). There was one incomplete ablation. One case with radiographic local recurrence was then proved by pathologic analysis of the nephrectomy specimen to have no cancer cells. The local tumor control rate was 98.1% (104/106). Of the 90 RCC cases, the disease-free survival rate was 97.8% (88/90); both the cancer-specific and the overall survival rate were 100%. No death or renal failure after the procedure has yet been found. Conclusions Our results showed that the laparoscopic RFA on small renal mass was safe, with outcomes of patients comparable with those by partial nephrectomy and percutaneous RFA. Further research and a longer follow-up period are needed to confirm our results.

Several studies have demonstrated the beneficial effects of omalizumab in asthma patients. Here we describe the drug's tolerance and oral corticosteroid sparing capacity in a long-term observational study.Thirty-two patients aged ≥18 years with obstructive airway disease and FEV(1) reversibility ≥12% and 200 mL, with an oral steroid requirement ≥7.5 mg per day of prednisolone during a period of ≥1 year, a positive prick test or in vitro reactivity (RAST) to at least one perennial aeroallergen and a baseline immunoglobulin E level ranking between 30-700 IU/mL were prospectively followed for 17.2 ± 8.5 months. Patients were visited once or twice a month, depending on their schedule for omalizumab administration.blood analysis every six months; spirometry and nitric oxide measurement at every visit.One patient who dropped out early was excluded. Follow-up period: the treatment benefited 83.9% (26/31) of the cohort; oral corticosteroids were reduced from 7.19 ± 11.1 to 3.29 ± 11.03 mg (p 0.002) and withdrawn in 74.2% of patients. FEV(1) (percent predicted) was 64.4 ± 22.7 at the beginning and 62.9 ± 24.3 at the end. IgE at entry was 322.2 ± 334.2 IU/mL and increased 2.34-fold. Respiratory function and NO did not present statistically significant changes. We identified three groups of patients: the first (n = 17) receiving oral steroid at entry in whom the accumulated dose of oral steroids progressively decreased; another (n = 10) including patients who had quit oral steroids before starting omalizumab although they had not been instructed to do so and whose oral steroid dose at the end of follow-up was zero; and a third group (n = 4) that did not benefit from omalizumab treatment. The only relevant side effect was a flu-like syndrome which required discontinuation of treatment in one patient.In our series, a substantial, safe decrease in oral corticosteroid requirements was observed due, at least to some extent, to omalizumab therapy. Oral corticosteroids were withdrawn in three-quarters of the patients. We were unable to identify a factor able to predict which patients would benefit most from omalizumab treatment.

Background: Despite the increase in the number of total knee arthroplasty revisions, outcomes of such surgery and their correlates are poorly understood. The aim of this study was to characterize patterns of functional improvement after revision total knee arthroplasty over a two-year period and to investigate factors that affect such improvement patterns. Methods: Three hundred and eight patients in need of revision surgery were enrolled into the study, conducted at seventeen centers, and 221 (71.8%) were followed for two years. Short Form-36 (SF-36), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and Lower-Extremity Activity Scale (LEAS) scores were collected at baseline and every six months for two years postoperatively. A piecewise general linear mixed model, which models correlation between repeated measures and estimates separate slopes for different follow-up time periods, was employed to examine functional improvement patterns. Results: Separate regression slopes were estimated for the zero to twelve-month and the twelve to twenty-four-month periods. The slopes for zero to twelve months showed significant improvement in all measures in the first year. The slopes for twelve to twenty-four months showed deterioration in the scores of the WOMAC pain subscale (slope = 0.67 ± 0.21, p < 0.01) and function subscale (slope = 1.66 ± 0.63, p < 0.05), whereas the slopes of the other measures had plateaued. A higher number of comorbidities was consistently the strongest deterrent of functional improvement across measures. The modes of failure of the primary total knee arthroplasty were instrument-specific predictors of outcome (for example, tibial bone lysis affected only the SF-36 physical component score [coefficient = −5.46 ± 1.91, p < 0.01], while malalignment affected both the SF-36 physical component score [coefficient = 5.41 ± 2.35, p < 0.05] and the LEAS score [coefficient = 1.42 ± 0.69, p < 0.05]). Factors related to the surgical technique did not predict outcomes. Conclusions: The onset of worsening pain and knee-specific function in the second year following revision total knee arthroplasty indicates the need to closely monitor patients, irrespective of the mode of failure of the primary procedure or the surgical technique for the revision. This information may be especially important for patients with multiple comorbidities. Level of Evidence: Prognostic Level II. See Instructions to Authors for a complete description of levels of evidence.

Echocardiography was performed at every six months in hypertensives well controlled on metoprolol, 100 mg twice a day. After six months' treatment blood pressure was reduced from 177/110 mm Hg to 147/88 (p less than 0.02). LV wall thickness (septum + posterior wall) was unchanged 2.10 cm (2.14), and a significant drop in cardiac output (CO) to 5.0 l/min (6.1, p less than 0.02) was recorded (pretreatment values in brackets). After 24 months' treatment LV wall thickness was reduced to 1.94 cm (p less than 0.02), total peripheral resistance (TPR) to 17.3 mm Hg/l/min (23.4, p less than 0.02) and CO increased to 6.7 l/min (6.1, n.s.). After six months' treatment, there was thus a drop in BP with a significant drop in CO and unchanged TPR. After 24 months' treatment, however, CO was back to the pretreatment level and the drop in BP was entirely caused by a drop in TPR which was probably secondary to a reduction in the wall thickness of the arterial resistance vessels as judged by the relationship between the reduction in wall thickness in the LV and the reduction in TPR during the treatment.

OBJECTIVE This study was deigned to evaluate the technique and clinical efficacy of the use of percutaneous transportal sclerotherapy with N-butyl-2-cyanoacrylate (NBCA) for patients with gastric varices. MATERIALS AND METHODS Seven patients were treated by transportal sclerotherapy with the use of NBCA. For transportal sclerotherapy, portal vein catheterization was performed with a 6-Fr sheath by the transhepatic approach. A 5-Fr catheter was introduced into the afferent gastric vein and a microcatheter was advanced through the 5-Fr catheter into the varices. NBCA was injected through the microcatheter in the varices by use of the continuous single-column injection technique. After the procedure, postcontrast computed tomography (CT) was performed on the next day and then every six months. Gastroendoscopy was performed at one week, three months, and then every six months after the procedure. RESULTS The technical success rate of the procedure was 88%. In six patients, gastric varices were successfully obliterated with 1-8 mL (mean, 5.4 mL) of a NBCA-Lipiodol mixture injected via a microcatheter. No complications related to the procedure were encountered. As seen on the follow-up endoscopy and CT imaging performed after six months, the presence of gastric varcies was not seen in any of the patients after treatment with the NBCA-Lipiodol mixture and the use of microcoils. Recurrence of gastric varices was not observed during the follow-up period. Worsening of esophageal varices occurred in four patients after transportal sclerotherapy. The serum albumin level increased, the ammonia level decreased and the prothrombin time increased at six months after the procedure (p < 0.05). CONCLUSION Percutaneous transportal sclerotherapy with NBCA is useful to obliterate gastric varices if it is not possible to perform balloon-occluded retrograde transvenous obliteration.

To evaluate the safety and efficacy of long-term glatiramer acetate (GA) therapy, 46 patients with relapsing—remitting multiple sclerosis (RRMS) were treated for up to 22 years in an ongoing, open-label study. Kurtzke expanded disability status scale (EDSS) was measured every six months, relapses were reported at occurrence and patients self-reported adverse events (AEs). At GA initiation, disease durations ranged from 0—20 years (median 6.0 years) and at data cut-off (October 2004), GA therapy duration ranged from 1—22 years (median 12.0 years). Mean EDSS score increased 0.9 ± 1.9 from the pretreatment score (3.0 ± 1.8; P = 0.076). Only 10/28 (36%) patients with baseline EDSS

Between September 2000 and September 2006, 26 patients underwent primary laparoscopic cryosurgical procedures (28) for an organ-confined renal tumor(s). In one case, cryosurgery was done sequentially on both kidneys. All patients had been carefully selected based on the following criteria: tumor size ≤ 3.5 cm, the absence of local and systemic spread on cross-sectional computed tomography (CT) or magnetic resonance imaging (MRI), and the ability to tolerate general anesthesia. A pure laparoscopic approach was employed using third generation cryotechnology (Galil Medical Inc., Plymouth Meeting, USA). Patients were followed by serial CT or MRI scan, creatinine level, and physical examination at least every six months after cryotherapy. The mean patient age was 64 years (range: 44–79) and the mean follow-up was 20.9 +/- 17.2 months. The median tumor size was 2.0 cm (range: 1–3.5 cm). Only one patient required a blood transfusion and one patient developed a transient ileus. The median length of stay was 2.0 days (range: 0–9 days). The median change in creatinine was 0.1 mg/dl (range:-0.4 to 1.8). No patient was converted to open surgery. No evidence of recurrence or progression was found in all patients, and overall survival rate was 100%. Laparoscopic renal cryoablation of the small renal tumor is a safe procedure with minimal complications. Although there were no recurrences with short term follow-up, further long term study is needed to verify its efficacy.

Research suggests that methylenedioxymethamphetamine (MDMA)/`ecstasy' can cause serotonin depletion as well as serotonergic neurodegradation that may result in depression. This longitudinal study used the Beck Depression Inventory (BDI-II) to assess depressive symptomatology every six months over a two-year period among a community sample of young adult MDMA/`ecstasy' users ( n = 402). Multilevel growth modeling was used to analyze changes in BDI scores. Between baseline and 24 months, the mean BDI score declined from 9.8 to 7.7. Scores varied significantly across individuals at baseline and declined at a rate of 0.36 points every six months. Persons with higher baseline scores were more likely to have their scores decrease over time. Several factors were significantly associated with score levels, independent of time: gender — men's scores were lower than women's; ethnicity — whites' scores were lower than those of non-whites; education — persons with at least some university education had scores that were lower than those without any college experience; benzodiazepines — current users' scores were higher than non-users'; opioids — current users' scores were higher than non-users'; and cumulative ecstasy use — people who had used MDMA more than 50 times had scores that were higher than persons who had used the drug less often. The results reported here show low levels of depressive symptoms among a sample that, after 24 months, consisted of both current and former MDMA users. The low and declining mean scores suggest that for most people MDMA/`ecstasy' use does not result in long-term depressive symptomatology.

Intravesical onabotulinumtoxinA (BoNT-A) injection can relieve symptoms of interstitial cystitis/bladder pain syndrome (IC/BPS), but lacks sustainability. Repeated injections have been shown to provide a superior outcome to a single injection, but data on long-term efficacy and safety is limited. In this prospective study, we enrolled patients with refractory IC/BPS, and treated them with 100 U of BoNT-A injection plus hydrodistention followed by repeated injections every six months for up to two years or until the patient wished to discontinue. A “top-up” dose was offered after the fourth injection. Of these 104 participants, 56.7% completed four BoNT-A injections and 34% voluntarily received the fifth injection due to exacerbated IC symptoms. With a follow-up period of up to 79 months, O’Leary-Sant symptom and problem indexes (ICSI, ICPI, OSS), pain visual analogue scale (VAS) functional bladder capacity, frequency episodes, and global response assessment (GRA) all showed significant improvement (p &lt, 0.0001). Those who received repeated injections had a better success rate during the long-term follow-up period. The incidence of adverse events did not rise with the increasing number of BoNT-A injections. A higher pre-treatment ICSI and ICPI score was predictive for successful response to repeated intravesical BoNT-A injections plus hydrodistention.

SummaryIn a previous paper, we published the impact of initial [18F]FDG PET/CT (FDG-PET/CT) in high-risk patients with differentiated thyroid cancer (DTC) and described the changes in therapy management. The aim of the present study was to evaluate the prognostic impact of the initial FDG-PET/CT on a patient’s follow-up over three years and the rate of complete remission. Patients, methods: This study included 109 DTC patients who underwent radioiodine treatment (RIT), including posttherapeutic whole-body scintigraphy with FDG-PET/CT and a follow-up over three years. The follow-up included high-resolution sonography of the neck and determination of serum Tg as well as Tg antibodies every six months. The results of initial FDG-PET/CT and whole-body scintigraphy were compared with the status after three years of follow-up. Results: 24/109 patients (22%) presented FDG-positive lesions, 22/109 patients (20%) only iodine-positive lesions, and 63/109 patients (58%) neither FDG-positive nor iodine-positive lesions. After three years, 83/109 patients (76%) revealed full remission, 15/109 patients (14%) tumour persistence and 11/109 patients (10%) a progressive disease. The negative predictive value (NPV) was calculated for patients without FDG-positive lesions (NPV 85%) and patients without any lesions (NPV 91%) regarding full remission in the follow-up. Conclusion: FDG-PET/CT has a high NPV (85% to 91%) in DTC patients regarding recurrence-free follow-up after three years. The change in patient management in patients with iodine-negative lesions can lead to a higher rate of full remissions in the follow-up after additional surgery. Therefore, FDG-PET/ CT should be performed in all high-risk DTC patients in the context of the first RIT to improve patient management and risk stratification.

Immunological monitoring is part of the standard of care for patients on antiretroviral treatment. Yet, little is known about the routine implementation of immunological laboratory monitoring and utilization in clinical care in Ethiopia. This study assessed the pattern of immunological monitoring, immunological response, level of immunological treatment failure and factors related to it among patients on antiretroviral therapy in selected hospitals in southern Ethiopia. A retrospective longitudinal analytic study was conducted using documents of patients started on antiretroviral therapy. Adequacy of timely immunological monitoring was assessed every six months the first year and every one year thereafter. Immunological response was assessed every six months at cohort level. Immunological failure was based on the criteria: fall of follow-up CD4 cell count to baseline (or below), or CD4 levels persisting below 100 cells/mm3, or 50% fall from on-treatment peak value. A total of 1,321 documents of patients reviewed revealed timely immunological monitoring were inadequate. There was adequate immunological response, with pediatric patients, females, those with less advanced illness (baseline WHO Stage I or II) and those with higher baseline CD4 cell count found to have better immunological recovery. Thirty-nine patients (3%) were not evaluated for immunological failure because they had frequent treatment interruption. Despite overall adequate immunological response at group level, the prevalence of those who ever experienced immunological failure was 17.6% (n=226), while after subsequent re-evaluation it dropped to 11.5% (n=147). Having WHO Stage III/IV of the disease or a higher CD4 cell count at baseline was identified as a risk for immunological failure. Few patients with confirmed failure were switched to second line therapy. These findings highlight the magnitude of the problem of immunological failure and the gap in management. Prioritizing care for high risk patients may help in effective utilization of meager resources.

This study analyzes the results of a follow-up policy in colorectal cancer at our institution and evaluates the possible benefit provided by each test performed. Six hundred nineteen patients who had radical surgery and adjuvant treatment for colorectal cancer were followed up with a protocol that included carcinoembryonic antigen testing and clinical examination every three months for the first two years, every four months in the third year, and every six months in the fourth and fifth years. Chest X-ray and colonoscopy were performed yearly for five years and abdominal ultrasound was done every six months for the first three years and yearly afterward. Abdominopelvic computerized tomography was performed yearly for the first two years in cases with rectal cancer. If relapse was detected, all operable cases underwent surgery if possible. Between 1993 and 1999, 619 patients were followed-up. Mean follow-up was 66.9 months. Two hundred eight relapses were detected, 83.6 percent in the first three years and 73 (35.1 percent) underwent surgical resection. Carcinoembryonic antigen testing detected 44.2 percent of recurrences and 31.9 percent of them were operated on. Imaging techniques detected a lower percentage of recurrences (18.7 percent) but were more often resectable: 52percent and 60 percent of the recurrences detected by computerized tomography and chest X-ray, respectively, underwent surgery. Median overall survival of patients with resected relapse was 62 months, significantly higher than those who were not operable (12.4 months). Imaging techniques in the surveillance of resected colorectal cancer contribute to early detection of relapse with a high proportion of operable metastatic disease.

Objectives: To evaluate the adaptability and the possible advantages of the antireflux mechanism of the serous lined extramural tunnel for ureter re-implantation on a gastrointestinal anastomosis (GIA) Stapler detubularised ileal neobladder Methods: From April 1998 to July 2002 43 male patients underwent radical cystectomy and the creation of a Camey II ileal neobladder using this antireflux technique. Follow-up in all cases included excretory urography or T.C. scan and a retrograde cystography at 6 months and a renal scintigraphy with DMSA at 1 year follow-up, besides serum creatinine, blood urea and serum electrolytes every three months and renal-neovesical ultrasound every six months. Results: Early and late complications were low. At follow-up 1 case of neovesico-ureteral reflux and 2 cases of ureteroileal anastomotic strictures were found. DMSA scintigraphy showed no further renal scars. Conclusions: This preliminary experience was favourable due to overall reduced operating time (about 1hour 45minutes to create the orthotopic neobladder and the ureteroileal anastomosis), simplicity of execution and a low complication rate (6.9%) at a median follow-up of 38 months (range 12–52 months).

The optimal age for surgery for infantile esotropia is controversial. Proponents of early surgery believe that further loss of binocular vision can be prevented by early surgery, a minority believes that binocular vision can even be restored by early surgery. The ELISSS compared early with late surgery in a prospective, controlled, non-randomized, multicenter trial.Fifty-eight clinics recruited children aged 6-18 months for the study. Each clinic operated all eligible children either 'early', i.e. at age 6-24 months, or 'late', i.e. at age 32-60 months. At baseline the angle of strabismus, refraction, degree of amblyopia and limitation of abduction were assessed. Intermediate examinations took place every six months. Children were evaluated at age six in the presence of independent observers. Primary endpoints were (i) level of binocular vision, (ii) manifest angle of strabismus at distance and (iii) remaining amblyopia. Secondary endpoints were number of operations, vertical strabismus, angle at near and the influence of surgical technique.A total of 231 children were recruited for early and 301 for late surgery. Age at entry examination was 11.1 months (SD 3.7 months) in the early group and 10.9 (SD 3.7) months in the late group. Refraction, amblyopia and limitation of abduction were distributed equally in the early and late groups, but the angle of strabismus was slightly larger in the early group. Dropout-rates were 26.0% in the early and 22.3% in the late group. At age six, 13.5% of the early vs. 3.9% of the late group recognized the Titmus Housefly; 3.0% of the early and 3.9% of the late group had stereopsis beyond Titmus Housefly. No significant difference was found for angle of strabismus. 35.1% of the early group and 34.8% of the late group did not have an angle between 0 degrees and 10 degrees , the thresholds set for re-operation. For ratio of the visual acuities (remaining amblyopia) there was a small but significant advantage for the early group. There was hardly any correlation between the baseline parameters and the primary endpoints. Children scheduled for early surgery had first been operated at 20 (SD 8.4) months, but 8.2% had not been operated at age six. Children scheduled for late surgery had been operated at 49.1 (SD 12.7) months, but 20.1% had not been operated at age six. The number of operations per child was 1.18 (SD 0.67) in the early and 0.99 (SD 0.64) in the late group. Age at recruitment, age that strabismus reportedly had started and refraction at entry examination were similar among operated and non-operated children. Only the angle of strabismus at entry predicted, to some extent, whether a child had been operated at age six.Children operated early had better gross stereopsis at age six as compared to children operated late. They had been operated more frequently, however, and a substantial number of children in both groups had not been operated at all.

Brain atrophy appears to occur in patients with multiple sclerosis (MS) in excess of that associated with normal ageing, and may be observed early in the clinical course of the disease. The dynamics and tissue specificity of this process remain unclear This preliminary study explored the evolution of brain grey matter (GM) and white matter (WM) volume loss (as fractions of total intracranial volumes) in 13 subjects with relapsing-remitting MS (mean disease duration 1.9 years at first scan), compared with nine normal control (NC) subjects. Subjects were scanned every six months for 18 months. In MS compared with NC subjects, significant differences in WM fractional volumes were observed at baseline (mean - 5.8%, P = 0.008) but no apparent progressive WM tissue loss was detected. In contrast, while no significant differences in GM fractional volumes were observed at baseline, there was significantly greater time-related volume loss in MS compared with NC subjects over the follow-up period (circa - 0.0086 per year in MS subjects, - 0.0021 per year in the NC subjects, difference P = 0.010). These results suggest that while both GM and WM atrophy are seen early in the clinical course of MS, they may not occur concurrently and may evolve at different rates.

To investigate whether hand bone mineral content (BMC) measurement is an outcome measure for RA and whether the early changes in hand BMC predict functional disability.Tender and swollen joints in hands and body, HAQ score, Larsen score on hand radiographs, serum CRP, and hand BMC measurement by DXA were studied every six months for five years in 40 patients with early RA. At the final visit, patients completed the SF-36 and Duruoz hand function questionnaires.All patients completed two years and 29 completed five years' follow up. Hand BMC worsened over the first three years (percentage loss from baseline: mean (SD) -5.5 (7.2), -7.5 (8.4), -9.8 (9.4)) and stabilised over last two years (-9.9 (8.8), -10 (7.8)). Baseline disease activity and function correlated with hand BMC loss at five years (swollen joints in hands: r=-0.38, p=0.043; swollen joints in body: r=-0.47, p=0.01; HAQ: r=-0.52, p=0.004). Percentage change in hand BMC over five years correlated with SF-36 physical function (r=0.61, p0.01), hand function (r=-0.64, p0.01), HAQ score (r=-0.63, p0.01) at five years. Relative risk of bad hand functional outcome at five years was significantly higher for patients with hand BMC loss of/=1.17 g (smallest detectable difference) than for patients with less bone loss within the first six months (OR=6.9, 95% CI 1.3 to 34.5, p0.02).Early loss of hand BMC in patients with RA is a composite marker of disease activity and functional status and can predict poor functional outcome.

In disabled and infirm patients with limited, if any, capacity for independent oral self-care, it is difficult to control progression of root caries lesions. Objective: To evaluate the effect of non-restorative cariostatic treatment on progression of active superficial root caries lesions (n =56). Design: Pilot study. Setting: Department of Cariology, Institute of Odontology, Karolinska Institutet, Huddinge. Subjects: 15 physically-dependent patients. Intervention: The patients were allotted to one of the following groups. Group 1, professional tooth cleaning and application of tap water flavoured with eucalyptus oil; Group 2, professional tooth cleaning and application of Cervitec, (1% chlorhexidine in thymol-containing varnish), Group 3, professional tooth cleaning and application of Cervitec and Fluor Protector (varnish containing 0.1% fluoride). Every three months for 18 months, each subject received the treatment twice within a 10-day interval. Measurements: The status of the 56 root caries lesions was evaluated every six months using a root caries index based on visual and tactile criteria. The examiners were blind to which treatment group the patients belonged. Results: In most subjects (14 out of 15), progression of root caries lesions was arrested. No statistically significant differences could be demonstrated between the three treatment groups. However, regardless of treatment regimen, there was a statistically significant difference between the greater number of subjects exhibiting no progression of root caries lesions and those with lesion progression, at 6 (p=0.022), 12 (p=0.006) and 18 months (p

Background The course of depression in residents of long-term care with dementia is not well studied. Objectives To estimate the incidence, prevalence, and outcomes of depression in long-term care residents with dementia. Method 201 residents of Copper Ridge, a long-term care facility for the memory impaired, were followed every six months during the first year after their admission. Results On admission 19.9% of the residents had depression, the majority (75%) occurring in persons with a prior history of depression. At six months, only 15% of the original 40 depressed patients were still depressed, while at twelve months only 7.5% were depressed. The incidence of depression at six and twelve months was 1.8% and 6.4% respectively. Most persons with new depression at six months were no longer depressed at one year. The annual attack rate (cumulative likelihood of depression over one year) for the total population was 26.4%. The rates for the subgroup of Alzheimer's were similar to the rates of the total population, except for an annual attack rate of 17.5%, reflecting a lower rate of depression on admission. The decline in depression over the year after admission is noteworthy and likely reflects appropriate diagnosis and treatment of depression. Conclusions These results indicate that, over the course of one year, depression afflicts a considerable proportion of long-term care residents with dementia. Admission to a long-term care facility may actually result in a reduction of depression within the year after admission in part due to rapid recognition, appropriate diagnosis and treatment.
