This study is a qualitative analysis of fathers' experiences of preterm birth. Preterm birth affects about ten per cent of the families globally. It is a traumatic event, especially when the infant is very preterm. Often, parents are struggling with the experience without any psychological support. Though fathers' role in the child's healthy psychological development has been confirmed by recent studies, the impact of preterm birth on their paternal identity and their needs for support in this emotionally burdening situation has not been studied extensively. We analysed ten interviews using Interpretative Phenomenological Analysis, a method to study sensitive themes to determine the key themes as potential areas of intervention. We could find that these fathers live their lives in extended liminality, characterized by chaos and unpredictability, and are struggling with new, often unusual roles and responsibilities that may completely upset their private life – work balance. The first contact with the child is usually ambivalent and is burdened with grave concerns about the potential harms. Communication at Perinatal Intensive Care Units (PICUs), though seen as supportive, is not tailored to fathers' competencies. Targeted intervention by trained counsellors at PICU could help the fathers overcome these traumatizing experiences. [ABSTRACT FROM AUTHOR]

Introduction: chondrosarcoma is the second most common primary malignant tumor, constitutes approximately one quarter of all primary bone sarcomas. Surgical margins in pelvic chondrosarcoma have a direct impact as a prognostic factor, both on overall survival and on recurrence-free survival of this disease. Objectives: to analyze the impact of surgical margins as a prognostic factor in pelvic chondrosarcoma. Material and methods: a retrospective database cohort with prospective follow-up of sarcomas in patients diagnosed with primary pelvic chondrosarcoma who underwent surgical treatment. Clinical-demographic variables were obtained, a descriptive analysis of each variable was performed, and these were contrasted with the outcome variables. Results: seventeen patients were included, of which nine were female. The median age was 41 years, ranging from 23 to 65 years. The average tumor size was 20.9 cm (range 5 to 46 cm). The average surgical margin was 5.3 mm, ranging from 1 to 30 mm, with 58% positive margins. The average overall survival was 64 months (range 7 to 108 months). The distribution of pelvic involvement was as follows: zone I in nine patients (52.9%), zone II in two (11.8%), a combination of zones I-III in two (11.8%), I+II in one (5.9%), II+III in one (5.9%), I-III plus sacrum in one (5.9%) and I plus sacrum in one (5.9%). Tumor grades were classified as low in seven patients (41.2%), intermediate in sven (41.2%), high in two (11.8%), and dedifferentiated in one (5.9%). Regarding the type of resection, 12 patients (70.6%) underwent internal hemipelvectomy and five (29.4%) external hemipelvectomy. Recurrence was recorded in five cases (29.4%), metastasis in three (17.6%), and mortality in four (23.5%). Conclusions: this series represents the largest cohort reported in Latin America of primary pelvic chondrosarcomas. A more favorable prognosis was observed in patients with surgical margins greater than 1 mm. The presence of chondrosarcoma in multiple pelvic zones was associated with a worse oncological prognosis. Additionally, a higher incidence of positive surgical margins and local recurrence rates were identified in pelvic chondrosarcomas compared to those located in the extremities.

Objective. Circumcision is one of the most common surgical procedures in pediatric surgery. Even though manual suture (MANS) is regarded as the gold standard technique, easy-to-use mechanical suture (MECS) devices have been recently developed, with better postoperative results in the adult population. The objective of our study was to compare the operating time and incidence of postoperative complications between both techniques in our environment. Materials and methods. A retrospective study of patients undergoing circumcision in our institution from October 2021 to December 2022 was carried out. Operating time and complications observed in the first 14 postoperative days (edema, hematoma, dehiscence) were analyzed according to the technique used (MANS vs. MECS) and patient age (< 12 and ≥ 12 years old). Results. 173 patients (147 MANS, 26 MECS) were included. Mean operating time was significantly lower in MECS patients, both in patients < 12 years old (16 min vs. 10 min, p= 0.002) and in patients ≥ 12 years old (23 min vs. 12 min, p< 0.001). Regarding complications, MECS patients ≥ 12 years old had a lower rate of suture dehiscence (23.5% vs. 0%, p< 0.001), with no significant differences in the younger group. Conclusions. MECS circumcision is a simple and effective technique involving shorter operating times than MANS circumcision, regardless of age. It has a lower rate of complications in older children (≥ 12 years), which means it stands as a valid alternative to the conventional technique. [ABSTRACT FROM AUTHOR]

Drug use and gambling are major problems in today's society. Many studies have found that school variables are related to drug use and gambling, but the persistence of such relationships in adulthood is still little-known. Therefore, the aim of this study was to discover if these school variables are related to substance use and gambling in both adolescence and adulthood through a retrospective study. A sample of 416 people resident in Spain between 18 and 50 years old was used. Results showed that having a good academic performance and a positive school environment act as protective factors for substance use. A high rate of truancy and disruptive classroom behaviors are risk factors for drug use and gambling. This relationship not only appears in adolescence, it also continues into adulthood. Results can be used for better prevention and intervention against drug use and gambling. [ABSTRACT FROM AUTHOR]

Purpose: Determine the frequency of histopathological diagnoses of 1978 biopsies of oral lesions in a period of 20 years in the city of Cali, Colombia. Methods: A retrospective descriptive observational study was conducted on 1978 histopathological diagnoses of biopsies of lesions in the oral cavity carried out during the period 2000-2022. The research is carried out in compliance with ethical requirements. The information was obtained from the records of biopsy reports of two oral pathologists from the city of Cali, the data collection was conducted by the seedbeds of 3 universities in Cali previously trained and calibrated. The information was unified in a single Excel database, the inclusion criteria were any age, any sex and complete reports. Descriptive statistical analysis was performed with the IBM SPSS Statics program. Results: Of the 1978 reports, 39 % corresponded to the male gender and 61% to the female gender. The average age was 45.33 ± 17.5 (Range 2-93). The most frequent histopathological diagnosis was hyperplasia (23.8 %), followed by granulomas (15.07 %). The gum (17.09 %), the periapical area (16.03 %) and the lips (13.30 %) were the sites that reported the most lesions. Histologically, connective tissue (51.82 %) and epithelial tissue (25.63 %) were the most reported, and the excisional biopsy technique was the most used (79.22 %). Conclusion: Hyperplastic oral lesions were the most frequent, they occurred more in women, in any site of the oral cavity and at any age. Proper diagnosis, performing biopsies and increasing evidence at the local and national level are especially important. [ABSTRACT FROM AUTHOR]

A didactic sequence designed to facilitate the understanding of the tides phenomenon and involve participants in modeling processes is presented. This involves the construction, revision and reconstruction of models, as well as reflection on their nature and their role in the teaching of science. The objective of this article is to describe and characterize said sequence, as well as its implementation in the classroom. This one follows the guidelines set by design based research: preparatory stage, two-cycle implantation stage, and retrospective study. The results of the preparatory study reaffirmed the difficulties in teaching and learning this topic: the teachers in the interviews showed its complexity in different areas, the analysis of the textbooks detected possible written and visual improvements, and the previous questionnaires identified in the students' initial ideas were far removed from the school science model. Regarding implementation, the proposed progression trajectory turned out to be appropriate, as was the organization of activities within the framework of modeling. In addition, improvements were obtained in the results of the second implementation cycle. Finally, the retrospective analysis involved the realization of two main types of changes in the initial sequence and detected a progression in the models of most of the students.

Abstract Objectives The course and long-term outcome of pure membranous lupus nephritis (MLN) are little understood. The aims of this study are to evaluate the clinical features, course, outcome and prognostic indicators in pure MLN and to determine the impact of ethnicity and the type of health insurance on the course and prognosis of pure MLN. Methods We conducted a retrospective review of medical records of 150 patients with pure MLN from Spain and the USA. Results Mean age was 34.2 ± 12.5 and 80% were women. Sixty-eight percent of patients had nephrotic syndrome at diagnosis. The average serum creatinine was 0.98 ± 0.78 mg/dl. Six percent of patients died and 5.3% developed end-stage renal disease (ESRD). ESRD was predicted by male sex, hypertension, dyslipidemia, high basal 24 h-proteinuria, high basal serum creatinine and a low basal creatinine clearance. Age, cardiac insufficiency, peripheral artheriopathy, hemodialysis and not having received mycophenolate mofetil or antimalarials for MLN predicted death. Conclusions Pure MLN frequently presents with nephrotic syndrome, high proteinuria and normal serum creatinine. Its prognosis is favourable in maintaining renal function although proteinuria usually persists over time. Baseline cardiovascular disease and not having a health insurance are related with poor prognosis. [ABSTRACT FROM AUTHOR]

The intestinal helminth infections that affect man are intimately linked to ecological, human and / or social conditions that may or not allow their persistence. The objective of the present study was to present the casuistry of the intestinal helminth infections that were diagnosed in the Clinical Laboratory of the Ambulatory Urban III Los Curos between the years 2012 to 2015. For that purpose, a retrospective investigation was carried out where they were studied for the period laboratory records were evaluated. The results evidenced 61.7% of parasitized individuals, 1.9% with some helminth (Ascaris lumbricoides, Trichuris trichiura, Strongyloides stercoralis, Enterobius vermicularis, Hymenolepis nana or Ancylostomideos). There was no difference between the presence of helminths and the demographic parameters age or sex. It is concluded that the ecoepidemiological conditions of Los Curos are not sufficiently adequate for the maintenance of intestinal helminth infections. [ABSTRACT FROM AUTHOR]

Fattening lambs in raised slatted floor cages systems has the advantage of clean and dryer facilities than allows a healthy environment, good ventilation, less parasite burden, protection from predation, reduced energy expenditure and best microclime for the animals; however, there is a lack on information about productive performance of lambs in such systems. Identifying factors affecting productive performance of the fattening lambs in raised slatted floor cages systems are crucial to improve their productivity. The aim of this study was to evaluate the effects of farm, year and year-season on some productive variables of lambs fattening in raised slatted floor cages in the subhumid tropic of Mexico. From a total of 882 male lambs of four farm (farm A, n = 166; farm B, n = 122; farm C, n = 350; farm D, n = 244) post-weaning daily weight gain (ADG), final body weight (FBW) and days of feedlot (DF) were analyzed. The statistical model included the fixed effects of farm (A, B, C and D), year-season (rainy and dry) and years (2010, 2011, 2012 and 2013) on ADG, FBW and DF. The model included the initial body weight as covariate. The overall means for GDP, PCF and DF were 263 g, 35 kg and 77 days, respectively. The farm affected (P < 0.001) all evaluated variables. The year-season affected (P < 0.001) PCF and DF, but not ADG. The year affected (P < 0.001) all evaluated variables. The interaction farm x year-season affected (P < 0.001) FBW and DF, but not ADG. In conclusion, the productive performance of lambs fattened in raised slatted floor cages in the subhumid tropic of Mexico, is affected for farm, year and partiality for year-season and interaction farm x year-season.

The present study was conducted to explore the relationship between victimisation during secondary school and aspects of current psychosocial functioning in university students. One hundred and sixty-one university students from Talavera de la Reina answered a self report questionnaire on retrospective bullying experiences and psychosocial functioning (self-concept, social support and perceived stress) during their school time. Results show that their recall of bullying experiences is consistent with other epidemiological data gathered in Spain. In addition, those who suffered more frequently from bullying scored lower on self-concept and social support, but not higher on perceived stress. [ABSTRACT FROM AUTHOR]

Objectives To describe the pattern of incident illness in children after initiation of antiretroviral therapy (ART) in a large public health sector programme in Lusaka, Zambia. Methods Systematic chart review to retrospectively extract data from medical records of children (i.e. <15 years) initiating ART in the Lusaka, Zambia public sector. Incident conditions were listed separately and then grouped according to broad categories. Predictors for incident diagnoses were determined using univariate and multivariable analysis. Results Between May 2004 and June 2006, 1705 HIV-infected children initiated ART. Of these, 1235 (72%) had their medical records reviewed. Median age at ART initiation was 77 months and 554 (45%) were females. Eight hundred and forty-one (68%) children had an incident condition during this period, with a median time of occurrence of 64 days from ART initiation. Twenty-eight incident conditions were documented. When categorized, the most common were mucocutaneous conditions [incidence rate (IR): 70.6 per 100 child-years, 95% CI: 64.5–77.2] and upper respiratory tract infection (IR: 70.1 per 100 child-years; 95% CI: 64.0–76.7). Children with severe immunosuppression (i.e. CD4 < 10%) were more likely to develop lower respiratory tract infection (16.3% vs. 10.2%; P = 0.003) and mucocutaneous conditions (43.9% vs. 35.3%; P = 0.005) than those with CD4 ≥ 10%. Conclusion There is a high incidence of new illness after ART initiation, emphasizing the importance of close monitoring during this period. Early initiation of ART and use of antimicrobial prophylaxis may also help to reduce the occurrence of such co-morbidities. [ABSTRACT FROM AUTHOR]

This article reveals the results of a descriptive investigation, which aim to describe by mean of retrospective method experiences of bullying and other forms of abuse within 648, freshmen students of a private university. The conclusions show that around 41.8% of the students were witnesses of this situation, 12% confessed that they were bullied o bullied someone else, 4.8% remembers to be a victim and other 13% claims to be both a victim and an aggressor. It can be said that bullying increases as students reach high school, yet many of the victims decide to remain silent, due to the fear of exclusion and retaliation. [ABSTRACT FROM AUTHOR]

The primary target of this study was to determine the level of individual elements protection use, in the diverse areas of work of the polled veterinarian in Argentine, as well as the ambient state of maintenance of work, related it to the frequency of pathologies displayed. The retrospective studies of the surveys made to veterinarians in professional exercise, during years 2003 to the 2006 inclusively, revealed events where injuries were taken place and labor diseases that affect workers quality of life. Activities like rectal tact, produced labor injuries in 11,5 % of the polled veterinarians, mainly due to traumas caused by animals. The acute Brucellosis was notified in 4,3 % of the total of received surveys, whereas 12,2 % were notified like chronic brucellosis. In this profession of risk, the development of strategies for diminishing labor dangers, sensitizing businessmen, professionals, students and workers from diverse sectors, is necessary to establish priorities in the use of elements of personal protection, the correct use of the material and work installations.
