Introduction Decreased serum magnesium levels are associated with mortality and fractures in patients with chronic kidney disease; however, there is no recommendation for Mg intake in these populations. Methods This study used cross-sectional analysis to examine the association between Mg intake and serum Mg levels in patients undergoing hemodialysis. Sixty-one patients were included. Results The daily Mg intake was 185 mg (IQR: 151-203 mg), and serum Mg level was 2.4 mg/dL (IQR: 2.2-2.7 mg/dL). Multiple regression analysis showed that intake of enteral formulation by tube feeding was an independent factor associated with serum Mg level (B = 0.90 [95% confidence interval: 0.61-1.20], p Conclusion These findings may aid in serum Mg level management through diet and enteral formulation in patients undergoing hemodialysis.

Discordant data have been reported on the prognosis of myocardial infarction with nonobstructive coronary arteries (MINOCA). Moreover, few data are available on the impact of angiographic subtypes. The objectives of this study were to assess the prognostic impact on the long-term follow-up of the diagnosis of MINOCA and its angiographic subtypes.We included 591 consecutive patients with non-ST-segment elevation myocardial infarction (NSTEMI) who underwent coronary angiography. MINOCA was classified according to angiographic findings as smooth coronary arteries, mild irregularities (30% stenosis), and moderate atherosclerosis (30%-49% stenosis). The primary endpoint was a composite of mortality, nonfatal myocardial infarction, and revascularization (MACE) at a median of 5 years of follow-up.A total of 121 patients (20.5%) showed no obstructive lesions. MINOCA was associated with a lower occurrence of MACE (P=.014; HR, 0.63; 95%CI, 0.44-0.91) and was confirmed as an independent factor in the multivariate analysis (P=.018; HR, 0.63; 95%CI, 0.43-0.92). On analysis of the separate components of the main endpoint, MINOCA was significantly associated with a lower rate of myocardial infarction and revascularization, but not with mortality. Analysis of angiographic subtypes among MINOCA patients showed that smooth coronary arteries were a statistically significant protective factor on both univariate and multivariate analysis, while mild irregularities and 30% to 49% plaques were associated with a higher risk of MACE.MINOCA is associated with a lower rate of MACE, driven by fewer reinfarctions and revascularizations. Within the angiographic subtypes of MINOCA, smooth arteries were independently associated with a lower number of MACE.

Objectives The present study aimed to evaluate human papillomavirus (HPV) occurrence in sinonasal inverted papilloma (SNIP), and to assess factors associated with HPV positivity and SNIP recurrence. Study design Prospective study. Methods We prospectively collected clinical data and fresh tissue specimens from 90 consecutive patients treated for SNIP at Helsinki University Hospital, between 2015 and 2019. Fourteen patients with recurrent SNIP underwent repeated tumor sampling. All tissue specimens were analyzed for the presence of HPV. Factors associated with SNIP recurrence and HPV positivity were assessed. Results Among 107 SNIP specimens, 14 (13.1%) were positive for low-risk HPV and 6 (5.6%) were positive for high-risk HPV. HPV positivity was associated with an increased risk of recurrence (P = .004). Smoking was significantly associated with HPV positivity in SNIP (P = .01), but a history of HPV-related diseases or patient sexual habits did not correlate with HPV positivity. The recurrence rate was lower among patients with SNIP that underwent an attachment-oriented resection, compared to patients treated without attachment-oriented resections (78.6% vs 25.8%, P Conclusions The risk of SNIP recurrence was highly associated with 1) HPV positivity and 2) surgery without an attachment-oriented resection. Oncogenic HPV was rare in SNIP. Level of evidence 3 Laryngoscope, 2021.

There is controversy in ophthalmic research as to whether vitamin D deficiency is an independent factor in the progression of myopia.

Objective of the research — to evaluate the efficacy of combined hypouricemic therapy in patients with hyperuricemia, urate nephropathy on the background of concomitant pathology (type 2 diabetes mellitus, hypertension) based on the dynamics of uricemia, uricosuria, the functional state of the kidneys, minimizing and eliminating the risk factors for the progression of chronic kidney disease. Sixty seven patients were involved in the study. Correction of hyperuricemia in patients with urate nephropathy and concomitant pathology (type 2 diabetes mellitus, hypertension) using phytodiuretic agent Urolesan® in combination treatment leads to normalization of metabolic processes, improvement of glomerular filtration rate, and a decrease in the level of albumin excretion.

Radiation-induced emesis (RIE) is usually noted during abdominal-pelvic radiotherapy. In gynecological malignancies, it is usually noted in para-aortic but not whole-pelvic irradiation. Irradiated small bowel (SB) may be associated with RIE. The significance of SB dosimetry remains unclear. Dosimetric and non-dosimetric factors were evaluated and correlated with RIE in 45 patients with gynecological malignancies undergoing extended-field radiotherapy (EFRT) (median 45 Gy) from 2006 to 2021. Early-onset RIE (within 72 h after the first fraction of EFRT) was noted in 10 of 12 RIE patients. RIE was significantly associated with the SB mean dose. The RIE rates were 58.3% and 15.2% (p = 0.007) in patients with a low (&lt, 63%) and high (≥63%) SB mean dose. Logistic regression revealed that the SB mean dose remained the independent factor of overall RIE (p = 0.049) and early-onset RIE (p = 0.014). Therefore, constraint of the SB mean dose limited to less than 63% of the prescribed dose is suggested to decrease RIE.

Blood pressure (BP) increased with age and height development, but little was known about the effect of pubertal development on blood pressure in children. A cross‐sectional study was performed among 4146 children aged 7–12 years old in China. Pubertal development was assessed based on breast stages and testicular volume. The associations of pubertal development with BP levels and the rate of elevated blood pressure (EBP) were quantified using multiple linear and logistic regressions. We found that pubertal developmental level was positively correlated with BP, and children who experienced puberty onset and early pubertal timing had higher BP levels and prevalence of EBP. After adjusting for covariates, children experienced puberty onset had 3.84 and 2.24 mmHg increase in systolic blood pressure and diastolic blood pressure, and 70%, 53%, and 62% increased odds of EBP, ESBP, and EDBP, respectively, compared with those without puberty onset. Similar results were observed for children who had early pubertal timing. The change of BP in puberty is greater and the association between pubertal development and BP is stronger in girls than boys. These findings suggested that pubertal development could be an important independent factor and one critical period for the EBP progress. Monitoring and management of pubertal development are necessary particularly among girls.

Descriptive and bivariate analyses were conducted, and the diagnosis of caries in the MSM and the position of the MTM were evaluated.Results: The posterior margin space of the MSM was larger in males (13.5 mm) than females (11.1 mm, P < 0.001) and correlated with the MTM’s impacted depth and eruption degree (P < 0.001). The prevalence of distal proximal caries of the MSM was 37.6%, and a χ2 test showed that age, impacted depth, impacted direction, impacted angle, degree of occurrence, and CEJ distance were correlated with caries in the distal adjacent surface of the MSM (P < 0.001). Logistic multivariate analysis showed that the impacted depth was at position A or B, the impacted direction was mesioangular, and the impacted angle was < 80°. Distal adjacent caries of MSMs were prone to occur when entirely or partially emergent. CEJ distance was not an independent factor for caries. The severity of caries in an MSM’s distal adjacent surface had statistical significance on the impacted depth and impacted angle (P < 0.001).Conclusion: The posterior margin space of the MSM influences the impacted condition of the MTM. Preventive extraction can be considered if the impacted angle is < 80°, especially in the case of a fully or partially emergent MTM at position A or B and mesioangular impacted areas.Keywords: mandibular third molar, dental caries, mandibular second molar, related factors

Using three-dimensional (3D) transesophageal echocardiography (TEE) and isometric handgrip exercise (IHE), we investigated the determinants of exercise-induced mitral regurgitation (MR) according to MR etiologies. Seventy-six patients with more than moderate MR, 40 patients with functional MR (FMR) and 36 patients with degenerative MR (DMR), underwent 3D TEE combined with IHE. Mitral valve (MV) geometry and 3D vena contracta area (3D VCA) were simultaneously evaluated at baseline and during IHE. With regard to exercise-induced MR, Δ3D VCA was calculated as the difference between 3D VCA at baseline and 3D VCA during IHE. IHE caused different changes in MV geometry between etiologies and led to exacerbation of 3D VCA at baseline. Larger Δ3D VCA was observed in the FMR group compared with the DMR group (15.9 ± 10.3 mm2 versus 7.3 ± 4.2 mm2; p < 0.0001). In multivariate analyses, tenting height and 3D VCA were selected as independent factors associated with Δ3D VCA in the FMR group (p = 0.0135 and p = 0.0201, respectively), while flail width was selected as an independent factor associated with Δ3D VCA in the DMR group (p = 0.0066). In conclusion, IHE alters mitral valve geometry and causes exacerbation of MR regardless of MR etiology and the determinants of exercise-induced MR differed between MR etiologies.

SUMMARY OBJECTIVE: Patients with chronic spontaneous urticaria often want to be informed about dietary modifications. There have been many studies evaluating dietary approaches in chronic spontaneous urticaria. In this study, we aimed to investigate the relationship between adherence to the Mediterranean diet and chronic spontaneous urticaria. METHODS: In this cross-sectional case-control observational study, 100 patients (70 males and 30 females, mean age: 38.6±13.0 years) with chronic spontaneous urticaria and age- and sex-matched 100 healthy controls 70 males and 30 females, mean age: 38.7±13.8 years) were enrolled. A validated 14-item questionnaire evaluating the Mediterranean diet score was used for the assessment of adherence to the Mediterranean diet. The severity and the control of chronic spontaneous urticaria were assessed by Urticaria Activity Score over 7 days and Urticaria Control Test, respectively. RESULTS: The mean Mediterranean diet score in the patient group was 5.40±1.88, whereas in healthy controls it was 6.30±1.39 (p

This paper addresses an interesting phenomenon with respect to sluicing in locative inversion where a mismatch in grammaticality is observed; that is, sluicing improves grammaticality while its full-fledged counterpart is ungrammatical. To account for the mismatch, the previous research often appealed to either “repair-by-ellipsis” or “evasion” strategies, but I argue that neither of them are legitimate for locative inversion constructions, in that no island violation is involved in the relevant examples or the conditions for making use of evasion strategies turn out not to be satisfied. As an alternative, I propose an in-situ analysis of sluicing, based on Abe (2015), in which no wh-movement is triggered as long as C[Q] and wh-phrase are adjacent in PF; this can be done by sluicing since PF-deletion on the TP would lead the two to be close to each other. Under the alternative, the wh-subject is focused and remains in-situ, followed by deletion of the TP constituent except the wh-phrase. The ungrammaticality of the full-fledged structure is due to an independent factor. Following Rizzi’s (1997) split CP-hypothesis, I argue that the wh-subject with focus cannot raise to a higher position than the locative PP. Thus, the in-situ approach explains the mismatch between sluicing and full-fledged sentences in locative inversion.

COVID-19 pneumonia represents a global threatening disease, especially in severe cases. Chest imaging, with X-ray and high-resolution computed tomography (HRCT), plays an important role in the initial evaluation and follow-up of patients with COVID-19 pneumonia. Chest imaging can also help in assessing disease severity and in predicting patient’s outcome, either as an independent factor or in combination with clinical and laboratory features. This review highlights the current knowledge of imaging features of COVID-19 pneumonia and their temporal evolution over time, and provides recent evidences on the role of chest imaging in the prognostic assessment of the disease.

One of the important tasks facing agriculture is to increase the production of high quality grain. It is known knowledge that the variety is a dynamic biological factor capable of realizing its genetic potential with a different combination of environmental factors and can act as a biological foundation for the production of high quality grain. The forecrop in modern agriculture acts as an independent factor in increasing grain yield and quality. The purpose of the current study was to estimate protein and gluten content in grain of winter bread wheat varieties of intensive type when sown after maize for grain and sunflower in the conditions of the Rostov region. The objects of the study were 9 winter bread wheat varieties of the intensive type developed in the FSBSI “ARC “Donskoy”. The study was carried out in the fields of the department of winter wheat breeding and seed production in 2018–2020. There were identified the varieties that formed the largest percentage of protein in grain on average over the years of study. They were the varieties ‘Etyud’, ‘Yubiley Dona’ and ‘Shef’ (12.44–13.06%) sown after maize for grain, and the varieties ‘Rubin Dona’, ‘Shef’ and ‘Zodiak’ (14.09–14.33%) sown after sunflower. There have been identified the varieties ‘Zodiak’ and ‘Yubiley Dona’ with the largest amount of gluten in grain on average over the years of study. They produced 24.63%, 25.53%, respectively after maize for grain; after sunflower they produced 28.20%, 27.66%, respectively. The results of two-way analysis of variance proved a greater effect of the factor ‘forecrop’ on protein and gluten content in grain of winter bread wheat than the effect of the factor ‘variety’ and their correlation.

Background Almost one-third of patients with diffuse large B-cell lymphoma (DLBCL) cannot be cured with initial therapy and will eventually succumb to the disease. Further elaboration of prognostic markers of DLBCL will provide therapeutic targets. IQ motif-containing GTPase activating protein 2 (IQGAP2) acts as a tumour suppressor in hepatocellular, prostate, and gastric cancers. However, the role of IQGAP2 in DLBCL remains unclear. Methods We collected mRNA expression data from 614 samples and the corresponding clinical information. The survival time of patients was compared between groups according to the mRNA expression level of IQGAP2. Survival analyses were performed in different subgroups when considering the effect of age, tumour stage, serum lactate dehydrogenase (LDH) concentration, performance status, and the number of extra nodal disease sites. The biological processes associated with IQGAP2-associated mRNAs were analysed to predict the function of IQGAP2. The correlation of IQGAP2 mRNA with immunosuppressive genes and leukocyte infiltration were analysed. Results The overall survival of patients with increased IQGAP2 mRNA levels was reduced even after aggressive treatment independent of age, tumour stage, serum LDH concentration, performance status, and the number of extra nodal disease sites. Furthermore, the biological processes of IQGAP2-associated mRNAs were mainly immune processes. IQGAP2 mRNA expression was correlated with the expression of immunosuppressive genes and leukocyte infiltration. Conclusion IQGAP2 mRNA is an independent prognostic factor and is related to immunosuppression in DLBCL. This discovery may provide a promising target for further development of therapy.

As end-of-life (EOL) care in nursing homes is gradually increasing, interprofessional collaboration in EOL care in nursing homes is becoming important. However, a method for measuring interprofessional collaboration has not been established. Therefore, this study aimed to clarify the effect of interprofessional collaboration on EOL care in nursing homes. Questionnaires were mailed to the facility directors of 378 nursing homes in Kanagawa Prefecture, Japan, and distributed to nurses, care managers, and professional caregivers. Three professionals from each nursing home completed the same questionnaire, which included 9 items on EOL care: shared facility policy, residents' wishes, each professional's roles, person in charge of the facility, residents' conditions, mental status of residents' families, emergency codes, residents' key people, and sufficient discussion among professionals. Based on the professionals' responses, interprofessional collaboration was assessed. We used multivariable analysis, with interprofessional collaboration as an independent factor. The outcome was the amount of EOL care in the nursing home. A total of 180 (47.6%) nursing homes participated. Multivariable analysis showed that interprofessional collaboration (beta [β] coefficient 2.5, 95% confidence interval [CI] 0.45-4.48; p = 0.017), availability of EOL care bonuses (β coefficient 4.4, 95% CI 1.41-7.38; p = 0.004), physician support for emergency care during off time (β coefficient 5.4, 95% CI 1.86-8.94; p = 0.003), and EOL care conferences (β coefficient 4.1, 95% CI 1.19-6.99; p = 0.006) were significant factors associated with the amount of EOL care in the nursing homes. We found evidence in the adjusted model that interprofessional collaboration among facility professionals is effective for EOL care in nursing homes.

Background and aims On March 11, 2011, the Great East Japan Earthquake occurred in Japan, with a nuclear accident subsequently occurring at the Fukushima Daiichi Nuclear Power Plant. The disaster forced many evacuees to change particular aspects of their lifestyles. This study assessed the association between evacuation and hyperuricemia based on the Fukushima Health Management Survey from a lifestyle and socio-psychological perspective. Methods and results This cross-sectional study included 22,812 residents (9391 men and 13,297 women) who underwent both the Comprehensive Health Check and the Mental Health and Lifestyle Survey in fiscal year 2011. Associations between hyperuricemia and lifestyle- and disaster-related factors including evacuation were estimated using a logistic and liner regression analysis. With hyperuricemia defined as uric acid levels >7.0 mg/dL for men and >6.0 mg/dL for women, significant associations were observed between evacuation and hyperuricemia in men (the multivariate-adjusted odds ratio 1.20, 95% confidence interval, 1.05–1.36, p = 0.005), but not in women. In the multivariate-adjusted multiple liner regression analysis, evacuation had significant and positive associations with uric acid levels both in men (β = 0.084, p = 0.002) and women (β = 0.060, p Conclusion Evacuation after a natural disaster is an independent factor associated with hyperuricemia.

Background and study aims Adequate removal of precancerous polyps is an independent factor in colorectal cancer prevention. Despite advances in polypectomy techniques, there is an increasing rate of surgery for benign polyps. We assessed whether surgical resection is properly utilized for benign colorectal polyps. Patients and methods We identified 144 patients with surgical resection for benign colorectal polyps. Polyp location, size and the indication for and type of surgery were obtained. For the purposes of this analysis, we assumed that gastroenterologists should assess polyp size accurately, endoscopically resect polyps Results A total of 118 patients (82 %) were referred to surgery without attempted endoscopic removal. In 26 (22 %) of 118, the macroscopic polyp size was Conclusions Of the patients, 41 % could have potentially avoided surgical intervention (37 polyps

Today it became a huge challenge for Human Resource Managers to retain the employees for longer time of period and decrease the rate of employee turnover. The main research objective is to find out the correlation between job satisfaction and employee turnover intention in private hospital in Erbil. A quantitative method was used to analyze the current study. 144 participants were involved in this study from private hospital in Erbil. The correlation between job satisfaction factor as independent factor and turnover as dependent factor, the value of R for the Job satisfaction is =.386** which indicates that turnover is a positive and weak correlation with turnover intention. The coefficients analysis for this study, the value Beta for turnover is = .386> 0.01, which supported the research hypothesis. This study showed that the there is a positive correlation between job satisfaction and employee turnover. Finally, on the turnover intentions of private hospital personnel in Erbil, most of them would quit in case if they have a better opportunities.

Background Little is known about the prevalence of a history of cancer and its impact on clinical outcome in mitral regurgitation (MR) patients undergoing transcatheter mitral valve repair (TMVR). Objectives The purpose of this study is to investigate the prevalence of cancer, baseline inflammatory parameters, and clinical outcome in MR patients undergoing TMVR. Methods Consecutive patients undergoing a MitraClip procedure were enrolled, and the patients were stratified into two groups: cancer and non-cancer. Baseline complete blood counts (CBC) with differential hemograms were collected prior to the procedure to calculate the platelet-to-lymphocyte ratio (PLR) and neutrophil-to-lymphocyte ratio (NLR). All-cause death within a one-year was examined. Results In total, 82 out of 446 patients (18.4%) had a history of cancer. Cancer patients had a significantly higher baseline PLR [181.4 (121.1–263.9) vs. 155.4 (109.4–210.4); P = 0.012] and NLR [5.4 (3.5–8.3) vs. 4.0 (2.9–6.1); P = 0.002] than non-cancer patients. A Kaplan–Meier analysis revealed that cancer patients had a significantly worse prognosis than non-cancer (estimated 1-year mortality, 20.2 vs. 9.2%; log-rank P = 0.009), and multivariable analyses of three models showed that cancer history was an independent factor for 1-year mortality. Patients who died during follow-up had a significantly higher baseline PLR [214.2 (124.2–296.7) vs. 156.3 (110.2–212.1); P = 0.007] and NLR [6.4 (4.2–12.5) vs. 4.0 (2.9–6.2); P Conclusions In MitraClip patients, a history of cancer was associated with higher inflammatory parameters and worse prognosis compared to non-cancer patients. Graphical Abstract Central Illustration. Clinical outcomes and baseline PLR and NLR values accord-ing to one-year mortality. (Left) Patients who died within the follow-up period had a significantly higher baseline PLR (214.2 [124.2–296.7] vs 156.3 [110.2–212.1]; P = 0.007) and NLR (6.4 [4.2–12.5] vs 4.0 [2.9–6.2]; P < 0.001) than patients who survived. PLR, platelet-to-lymphocyte ratio; NLR, neutrophil-to-lymphocyte ratio (Right) A Kaplan-Meier analysis revealed that cancer patients had a significantly worse prognosis than non-cancer patients (estimated one-year mortality, 20.2 vs 9.2%; log-rank P = 0.009).

Objectives To evaluate the efficacy and safety of ultraslow full-power shock wave lithotripsy protocol in the management of high attenuation value upper ureteric stones compared with slow-rate, power-ramping shock wave lithotripsy. Methods This was a randomized trial enrolling patients with a single high attenuation value (≥1000 HU) upper ureteric stones between January 2019 and July 2019. Ultraslow full-power shock wave lithotripsy (54 patients) was applied at a rate of 30 shock waves/min with power ramping from 6 to 18 kV for 100 shock waves, then a safety pause for 2 min, followed by ramping 18-22 kV for 100 shock waves, then a safety pause for 2 min. Then, full power (22 kV) was maintained until the end of the session. Slow-rate, power-ramping shock wave lithotripsy (47 patients) was applied at a rate of 60 shock waves/min with power ramping from 6 to 10 kV during the first 500 shock waves, then from 11 to 22 kV during the next 1000 shock waves, then maintained on 22 kV in the last 1500 shock waves. Up to three sessions were carried out with a follow up 3 months after the last session. The primary outcome was the stone-free rate. Perioperative data of the two protocols were compared. Results There was no significant difference in preoperative data. The stone-free rate was significantly higher in ultraslow full-power shock wave lithotripsy after single (92.6% vs 23.4%) and multiple (96.3% vs 63.8%) sessions. Most complications were mild, with no significant difference between both groups (9.3% vs 12.8%; P = 0.573). Logistic regression analysis identified ultraslow full-power shock wave lithotripsy protocol as the only significant independent factor for the stone-free rate (odds ratio 12.589, P = 0.025). Conclusion Ultraslow full-power shock wave lithotripsy for high attenuation value upper ureteric stones is associated with a significantly higher stone-free rate, and with mild complications that are comparable to those of standard shock wave lithotripsy.

It remains unclear about the role of the EVI1 gene in AML patients with 11q23/MLL rearrangement (MLL-r AML) undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT). We analyzed the clinical value of EVI1 gene quantification in 96 MLL-r AML patients. High EVI1 expression was found in 73% (70/96) of MLL-r AML patients, and EVI1-high MLL-r AML patients were characterized by high WBC counts (P = 0.046) and low platelet counts (P

Purpose To compare outcomes of manual Descemet membrane endothelial keratoplasty (M-DMEK) and femtosecond laser–assisted Descemet membrane endothelial keratoplasty (F-DMEK) in treatment of penetrating keratoplasty (PK) graft failure. Methods S etting : Retrospective, interventional comparative case series. P atient P opulation : Included were all patients with a failed PK graft who underwent either F-DMEK (10 eyes of 10 patients) or M-DMEK (29 eyes of 29 patients) at Toronto Western Hospital and the Kensington Eye Institute between 2014 and 2019, and had 6 months of postoperative follow-up. O utcome M easures : Rates of graft detachment, rebubbling, rejection and failure, best spectacle-corrected visual acuity (BSCVA), and endothelial cell (EC) density. Results Rate of significant graft detachment (detachment requiring either rebubble or repeat keratoplasty) was 10.0% in F-DMEK and 65.5% in M-DMEK (P = .003). Rebubble rate was 10.0% in F-DMEK and 58.6% in M-DMEK (P = .011). Primary failure rate was 0% in F-DMEK and 27.6% in M-DMEK (P = .086). Rates of rejection and secondary failure did not differ between the groups (P = 1.000 for both). In a multivariable analysis, F-DMEK was found to be the only independent factor significantly associated with reduced postoperative detachment. Postoperative BSCVA at 6 months returned to prefailure levels in both groups, with no significant difference between the groups at any time point. EC loss rates were 43.8% in F-DMEK and 38.0% in M-DMEK at 6 months (P = .453). Conclusions F-DMEK is a safe and effective procedure in failed PK patients, with outcomes comparable to M-DMEK, and with reduced detachment and rebubble rates. A trend towards reduced primary failure should be further studied.

Aim: Gastric cancer (GC) is one of the most common malignant tumors in the world. It is important to find accurate and reliable biomarkers in order to decrease whole morbidity and mortality. Results: We examined the expression of COX-2 and mTOR on GC tissue microarrays by immunohistochemistry. Multivariate COX regression analysis showed that the expression of COX-2 or mTOR was an independent factor in the prognosis of GC patients. In addition, COX-2 and mTOR have a potentially synergistic effect on predicting the prognosis of GC. Conclusion: The combined expression of COX-2 and mTOR could serve as efficient prognostic indicators and COX-2 could suppress GC metastasis via regulating mTOR.

ObjectivesPrevious studies have reported that cases with clinical T1 renal cell cancer upstaging to pathological T3 are a risk factor to predicting postoperative recurrence after partial nephrectomy. The aim of our study was to investigate the impact of the radiological morphology of the enhanced CT scan of clinical T1 renal cell cancer on predicting upstaging to pathological T3.MethodsThree hundred sixty-seven cases with clinical T1 renal cell cancer diagnosed from enhanced CT scans were enrolled in this study. Based on the findings from the enhanced CT scan, the cases were classified into ‘round’, the margins of which were smooth and round; ‘lobular’, one or more findings of smooth dent and no spiky dent were identified on the margin of the tumor; and ‘irregular’, one or more spiky dent were identified on the margin of the tumor. The association of postoperative upstaging with these radiological morphology and other clinical characteristics of each case was analyzed.ResultsEighteen cases (4.9%) pathologically upstaged to T3a. Two round case (0.7%), 3 lobular cases (10.0%) and 13 irregular cases (22.0%) pathologically upstaged (P ConclusionsEvaluation of the radiological morphology of clinical T1 renal cell cancer based on enhanced CT scans is useful for predicting pathological upstaging.

Although fatigue is an expressive symptom of Parkinson’s disease (PD), few studies have investigated the association between fatigue, mobility and walking capacity of these patients. Objective: To investigate whether fatigue is an independent factor associated with mobility and the walking capacity in patients with PD. Methods: Forty-eight patients with PD (22 with fatigue) were tested for mobility and their walking capacity: Timed Up and Go (TUG), 10-Meter Walk Test (10MWT) at usual and fastest speed, and 6-Minute Walk Test (6MWT). Fatigue was measured with Parkinson’s Fatigue Scale (PFS-16). Linear regression analysis was used to investigate if fatigue is an independent factor contributing to variance in mobility and walking capacity. Results: There was a positive correlation between PFS-16 and TUG (rs=0.385; p=0.007). There was a negative correlation between PFS-16 and 10MWT at comfortable (r=-0.385; p=0.007) and fast speeds (r=-0.396; p=0.005), and 6MWT (r=-0.472; p=0.001). Linear regression analysis revealed that fatigue did not explain the variance of TUG and 10MWT. PFS-16, age and section III of UPDRS explained 49.6% (adjusted R2; p

Background/aim The efficacy and safety of early drain removal following distal pancreatectomy in elderly patients are unclear. We aimed to investigate the short-term surgical outcomes following early drain removal after distal pancreatectomy in elderly patients. Patients and methods Fifty-seven patients aged ≥70 years who underwent distal pancreatectomy at our Hospital were enrolled in the study. Data were retrospectively analyzed to evaluate the short-term surgical outcomes following early drain removal after distal pancreatectomy in elderly patients. Results The incidence of pancreatic fistula following distal pancreatectomy in the early-removal group was significantly lower vs. the conventional group (p=0.022). Multivariate analysis revealed that early drain removal was an independent factor for reducing the risk of pancreatic fistula after distal pancreatectomy in elderly patients (p=0.042). Conclusion Early drain removal following distal pancreatectomy is an effective and safe surgical perioperative management procedure to prevent pancreatic fistula in elderly patients.

Pancreatic fistula (PF) is a common and serious complications after pancreaticoduodenectomy (PD). However, few studies have discussed the time required for PF healing in patients with this complication. This study investigates the PF healing time (PF-HT) and its association with findings of postoperative fistulography performed via the drainage tubes. The subjects of this study were 35 patients with PF among a total of 144 patients who underwent PD for periampullary diseases in our hospital. PF-HT, which was defined as the duration from the first postoperative fistulography to removal of the drainage tubes, was assessed in the enrolled patients. Fistulography findings were classified into four types based on fluid collection and communication with the jejunal loop. We investigated the factors affecting the PF-HT, including the fistulography findings. The average PF-HT was 22 ± 20 days. Multivariate analysis revealed that the fistulography type was the only independent factor that affected PF-HT significantly. The PF-HT was significantly shorter in patients without fluid collection than in those with fluid collection. Moreover, those patients with fluid collection and a communication had a significantly shorter PF-HT than those without a communication. We found that fistulography findings were significantly associated with the PF-HT. This suggests that fistulography findings could help to predict the time needed for PF healing.

BACKGROUND AND OBJECTIVES: To examine the association between hospital surgical volume and perioperative mortality of pelvic exenteration performed for gynecologic malignancies. METHODS: A population-based retrospective study utilizing the Nationwide Inpatient Sample was conducted to examine pelvic exenteration for gynecologic malignancies from 2001 to 2011. Annualized hospital surgical volume was defined as the average number of procedures a hospital performed per year in which at least one case was performed, and this was correlated to perioperative mortality. RESULTS: A total 1912 exenterations performed at 181 centers were included. Nearly two thirds of exenteration-performing centers had a minimum surgical volume of one case per year (121 centers, 66.9%). Perioperative mortality rate was 1.8%. In multivariable analysis surgical volume remained an independent factor for perioperative mortality (adjusted-odds ratio 0.21; 95% confidence interval, 0.09–0.49; P < .001). Perioperative mortality rates were 3.7% for the centers with minimum surgical volume (1 exenteration a year), 1.4% for the centers performing more than one but two or less exenterations a year, and 0% for the top decile centers (>2 exenterations a year), respectively (P < .001). CONCLUSION: Pelvic exenteration for gynecologic malignancy is a rare surgical procedure with most hospitals performing few cases annually. A higher surgical volume of pelvic exenteration was associated with lower perioperative mortality.

Urbanization has caused an increase in favorable habitats for Aedes aegypti (Diptera: Culicidae), given their ability to reproduce in small and often non-degradable artificial water-containers. While much work has been done on Ae. aegypti biology and ecology in urban landscapes, the role of shading on immature stages as an independent factor from temperature, and any possible interactions between these factors, remains unexamined. We assessed how temperature and shading affected egg hatch-rate, larval/pupal mortality, and larval development to adult stage under different factorial temperature (28; 31; 34; 37; 40° C) and shade (0%, 3,100 lux; 40%, 1,860 lux; 75%, 775 lux; 100%, 0 lux) regimes. Hatch-rate was significantly lower at 37° C (57 %), and no eggs hatched at 40° C. There was no significant effect caused by shading on hatchability. Larval and pupal mortality at 37° C was significantly higher (35%) compared to lower temperature groups, while the effects of shading were emergent at low temperatures. Developmental times from hatching to adult emergence were significantly reduced with increasing temperatures and with greater light exposures. The eco-physiological response of Ae. aegypti larvae to temperature and light regimes suggest a photosensitivity previously unstudied in this species.

BACKGROUND External ear melanoma (EEM) is a rare condition with controversies in the literature. We analyzed patients with EEM in the United States compared to other head and neck melanomas (OHNMs). METHODS The National Cancer Database (NCDB) was used to select patients with head and neck melanoma from January 1, 2004 to December 31, 2015. Mann-Whitney and χ tests were used to estimate statistical significance, and multivariate logistic regression to identify independent associations adjusted for confounders. RESULTS A total of 137,233 patients met the study criteria. Among them, 16,991 (12.4%) had EEM and 120,242 (87.6%) had OHNM. For patients with EEM, the mean (standard deviation) age was 66.26 (15.798) years. Most of the patients with EEM were men (85.5%), insured by Medicare (52.4%), and treated in Academic/Research Programs (47.7%) or Comprehensive Community Cancer Programs (32.3%). Most of the EEM tumors had invasive behavior (68.0%) were Stages 0 (30.3%) or I (40.3%), and were without ulceration (76.9%). Mean time to receive any treatment was 14.1 days for EEM compared with 14.6 days for OHNM (P

Accumulated evidence have revealed profound associations between C1q/TNF-related proteins (CTRPs) and coronary artery disease (CAD); yet, the relationship of CTRP4 to CAD has not been investigated. We examined the role of CTRP4 in CAD, and especially in acute coronary syndrome (ACS). METHODS A total of 138 patients referred for coronary angiography were included in this study and were classified into 3 groups (ACS, CAD and control group). Comparisons regarding clinical data and CTRP4 concentration were performed among 3 groups. Weighted least-squares regression analysis was used to identify the independent predicting factors for CTRP4. RESULTS Compared with either CAD (median 7.19 vs. 9.43, P

espanolEl melanoma de piel cabelluda (MPC) es una neoplasia cutanea que se presenta con frecuencia en hombres mayores de 60 anos, acompanada de disminucion de la densidad capilar, ademas de la exposicion solar acumulada. La topografia se ha considerado un factor independiente de mal pronostico, en relacion con una mayor recurrencia local y menor sobrevida. El MPC posee un patron de crecimiento vertical y por tanto mayor probabilidad de metastasis regional y a distancia, debido al abundante drenaje linfatico y sanguineo propio de la piel cabelluda. En la variante amelanica se observa una tasa de diagnostico clinico erroneo cercana al 89%. EnglishScalp Melanoma is a cutaneous neoplasm that frequently occurs in men over 60 years-old, its associated with less hair density, plus accumulative sun exposure. This localization is an independent factor of poor prognosis, related to higher local recurrence and less survival. This variant shows a vertical growth pattern and an increased risk of regional and distant metastases due to the scalp’s own lymphatic and blood drainage pattern. When it presents as amelanotic melanoma, it represents a rate of clinical misdiagnosis close to 89%.

Several basic researches have indicated that there is a significant relationship between bile reflux and the pathogenesis of Barrett’s esophagus (BE). However, only few clinical studies have been reported regarding the endoscopic finding of bile reflux and Barrett’s esophagus. Our objective is to evaluate whether the endoscopic evidence of bile reflux is an independent factor associated with the presence of BE. Methods We conducted a retrospective analysis of a prospectively maintained database comprised of consecutive Japanese patients who underwent screening gastroscopy. Endoscopic findings of BE, reflux esophagitis, atrophic gastritis and sliding hernia were recorded. Evaluation of a BE was based on the Prague criteria. Endoscopic evidence of bile reflux was defined as the presence of yellow or green juice observed by white light image or red juice by narrow band image (NBI) in the gastric fundus. Univariate and multivariate analyses were performed to identify factors that differed significantly between patients with or without BE. Results A total of 454 patients were enrolled; 124 (27%) had BE and 126 (28%) had endoscopic evidence of bile reflux. Compared to patients without BE, patients with BE were more likely to be old, male and to have sliding hernia and endoscopic evidence of bile reflux on univariate analysis. On multivariate analysis, endoscopic evidence of bile reflux was a stronger independent factor associated with BE (odds ratio(OR) 11.3, 95% confidence interval(CI) 6.56–19.4) compared to the presence of sliding hernia (OR 3.58, 95%CI 2.14–6.0). Conclusion Endoscopic evidence of bile reflux identified by white light or NBI is a strong independent factor associated with the presence of BE, implying that this finding should be considered as an important parameter to determine the surveillance strategy for gastroesophageal reflux disease patients same as the presence of sliding hernia.

Introduction. It is of great significance to confirm reliable indicators for the guidance of pretransplant radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC). In this study, we aim to investigate whether circulating tumor cell (CTC) status is a clinical indicator for RFA before liver transplantation (LT) in HCC patients. Method. CTC analyses were measured in 79 HCC patients. Clinical outcomes including progression-free (PFS) and overall survival (OS) were compared and analyzed between patients with and without pretransplant RFA. Result. Forty-two patients were detected as CTC-positive and 18 patients received pretransplant RFA. Recurrence was correlated with CTC count ( P = 0.024 ), tumor number ( P = 0.035 ), liver cirrhosis ( P = 0.001 ), Milan criteria ( P = 0.003 ), and University of California San Francisco (UCSF) criteria ( P = 0.001 ). Kaplan–Meier analysis revealed that patients with CTC-positive had a lower PFS rate ( P = 0.0257 ). For CTC-positive patients, the PFS rate of the pretransplant RFA group was significantly higher than the non-pretransplant RFA group (100% vs. 46.7%, P = 0.0236 ). For CTC-negative patients, both PFS rate and OS rate were similar and without significant differences. In multivariate analysis, pretransplant RFA was the independent factor for PFS ( P = 0.025 ). Conclusion. Pretransplant CTC status can guide the administration of pretransplant RFA in HCC patients which can improve PFS in CTC-positive HCC patients.

Objective Obesity is a strong and independent factor for the development of atrial fibrillation (AF), and adversely impacts the success of catheter ablation procedures for AF. This study evaluated the impact of body mass index (BMI) on the outcomes following surgical ablation of AF. Methods Between 2003 and 2019, 236 patients underwent a stand-alone biatrial Cox maze IV procedure (CMP-IV) for refractory AF. Obesity was defined as BMI ≥30 kg/m2. Patients were divided into two groups: BMI 2 ( n = 100) and BMI ≥30 kg/m2 ( n = 136). Freedom from atrial tachyarrhythmia (ATA) was determined using electrocardiography, Holter, or pacemaker interrogation at 1 year and annually thereafter. Recurrence was defined as any documented ATA lasting ≥30 s. Predictors of recurrence were determined using multivariable logistic regression. Preoperative and procedural outcomes were compared between groups. Results Obese patients had a higher rate of diabetes (16% vs 7%, P = 0.044) and larger left atrial diameter (4.9 ± 1.1 cm vs 4.6 ± 1.0 cm, P = 0.021) when compared to non-obese patients. There was no difference in major complication rate between the groups (4% vs 7%, P = 0.389). There was no operative mortality in either group. During 4.1 ± 2.4 years of follow-up, there was no significant difference in freedom from ATA with or without antiarrhythmic drugs in obese patients when compared to the non-obese group ( P > 0.05). Absence of sinus rhythm at discharge predicted AF recurrence up to 7 years postoperatively. Conclusions As opposed to catheter ablation, obesity did not adversely impact the short and long-term outcomes of stand-alone surgical ablation with CMP-IV, and BMI was not a predictor of AF recurrence. Additionally, there was no significant increase in major complications in obese patients.

Purpose To evaluate the relationship between kinesiophobia and patient's return to sport after shoulder stabilization surgery. The hypothesis was that kinesiophobia represents an independent factor correlated to the difference between preinjury and postoperative level of sport. Methods This study retrospectively evaluated 66 patients (mean age: 35.5, standard deviation [SD] = 9.9 years) and at a mean follow-up of 61.1 (SD = 37.5) months after arthroscopic Bankart's repair or open Bristow–Latarjet procedure. Kinesiophobia was assessed with the Tampa Scale for Kinesiophobia (TSK); return to the preinjury sport was assessed by the difference between baseline and postoperative degree of shoulder involvement in sport (D-DOSIS) scale. The Western Ontario Shoulder Instability index (WOSI) was used to evaluate participants' perceptions of shoulder function. Results TSK showed correlation with D-DOSIS (ρ = 0.505, p Conclusion This study demonstrated that kinesiophobia is correlated to the return to sport after shoulder stabilization surgery. Level of Evidence Level IV, retrospective case series.
