Background An important focus of rehabilitation is thereturn to the meningful occupations which may include work and school activities. Purpose The aim of this study is to investigate predictive factors for return to work/study in traumatic brachial plexus injury patients undergoing rehabilitation and to investigate the level of satisfaction with treatment. Study Design Retrospective observational study with at least 1 year of follow-up. Methods One hundred and one individuals with traumatic brachial plexus injury enrolled in this study. Primary outcomes were return to work/study and satisfaction with treatment. A secondary outcome was the self-perception of what influenced return to work. Sociodemographic and related to injury data, rehabilitation interventions, muscle strength, and disability were analyzed as predictors. Associations were investigated using univariable and discriminant analysis and considered a level of significance of P Results Return to work/study occurred in 55% of the patients who participated in this study. Muscle strength discerned those who returned to work. Time interval between trauma and surgery and age were lower in those who returned to work. Thirty-one patients answered the question regarding self-perception of what influenced return to work. They indicated “necessity”, “rehabilitation”, “my desire” and “not become depressed”. Satisfaction was graded between 8.9 and 9.5 in 95% of the cases. Conclusions Return to work/study was related to muscle strength improvement and those who returned were younger and had less time elapsed from trauma. Individual factors and rehabilitation were pointed out as helpful in aiding return to work. Satisfaction with treatment was high. These findings can help to optimize goals in the rehabilitation environment.

Rationale and Objectives To date, no clinically useful classification system has been developed for reliably differentiating mucinous cystic neoplasm (MCN) from a benign hepatic cyst (BHC) in the liver. The objective was to use machine learning and a multi-center study design to develop and assess the performance of a novel classification system for predicting whether a hepatic cystic lesion represents MCN or BHC. Materials and Methods A multi-center cohort study identified 154 surgically resected hepatic cystic lesions in 154 subjects which were pathologic confirmed as MCN (43) or BHC (111). Readers at each institution recorded seven pre-determined imaging features previously identified as potential differentiating features from prior publications. The contribution of each of these features to differentiating MCN from BHC was assessed by machine learning to develop an optimal classification system. Results Although several of the assessed imaging features demonstrated statistical significance, only 3 imaging features were found by machine learning to significantly contribute to a potential classification system: (1) solid enhancing nodule (2) all septations arising from an external macro-lobulation (3) whether the lesion was solitary or one of multiple cystic liver lesions. The optimal classification system had only four categories and correctly identified 144/154 lesion (93.5%). Conclusion This multi-center follow-up study was able to use machine learning to develop a highly accurate classification system for differentiation of hepatic MCN from BHC, which could be readily applied to clinical practice.

Background: Definitive closure of fistula-in-ano poses an ongoing surgical challenge. The OVESCO OTSC® Proctology Clip (proctology clip) purports to offer improved preservation of the anal sphincter whilst at the same time curing the fistula by closure. Methods: A retrospective record review was conducted for patients who received the proctology clip as part of the management of fistula-in-ano in the Colorectal Unit at Wits Donald Gordon Medical Centre (WDGMC). Results: There were 19 cases of fistula-in-ano treated with the proctology clip. All were cryptoglandular in origin. The median age was 50 years (IQR 44–56 years) and post-procedure, the median follow-up duration was 145 days (IQR 63–298 days). Overall, 9 procedures were successful (47%). Success rates were higher for simple (66.7%) as opposed to complex (38.5%) fistula-in-ano. For patients who underwent placement of the proctology clip as a primary procedure, the success rate (50%) was slightly better than those who received the clip as a secondary procedure (44.4%). Conclusion: This preliminary data presents our initial experience using the proctology clip. While these data may serve as a “proof of concept”, a multi- centre controlled trial comparing this method to the rectal mucosal advancement flap (RMAF) is needed to determine the role of the proctology clip in the management of fistula-in-ano.

Background: Accumulating evidence highlights the existence of distinct morphological subtypes of intracranial carotid arteriosclerosis. So far, little is known on the prevalence of these subtypes and subsequent stroke risk in the general population. We determined the prevalence of morphological subtypes of intracranial arteriosclerosis and assessed the risk of stroke associated with these subtypes. Methods: Between 2003 and 2006, 2391 stroke-free participants (mean age 69.6, 51.7% women) from the population-based Rotterdam Study underwent noncontrast computed tomography to visualize calcification in the intracranial carotid arteries as a proxy for intracranial arteriosclerosis. Calcification morphology was evaluated according to a validated grading scale and categorized into intimal, internal elastic lamina (IEL), or mixed subtype. Follow-up for stroke was complete until January 1, 2016. We used multivariable Cox regression to assess associations of each subtype with incident stroke. Results: The prevalence of calcification was 82% of which 39% had the intimal subtype, 48% IEL subtype, and 13% a mixed subtype. During a median follow-up of 10.4 years, 155 participants had a stroke. All 3 subtypes were associated with a higher risk of stroke (adjusted hazard ratio [95% CI] for intimal: 2.11 [1.07–4.13], IEL: 2.66 [1.39–5.11], and mixed subtype 2.57 [1.18–5.61]). The association of the IEL subtype with stroke was strongest among older participants. The association of the intimal subtype with stroke was noticeably stronger in women than in men. Conclusions: Calcification of the IEL was the most prevalent subtype of intracranial arteriosclerosis. All 3 subtypes were associated with an increased risk of stroke, with noticeable age and sex-specific differences.

Background Nasogastric (NG) feeding tubes are used to deliver nutrition, hydration, and medications to hospitalized infants and children but the ongoing use of non-evidence-based practice (EBP) methods to confirm NG tube (NGT) placement has been associated with adverse patient events. Methods A study was undertaken to ascertain if practice changes have occurred since findings from a previous study were published by the New Opportunities for Verification of Enteral tube Location (NOVEL) project. The NOVEL project was an initiative of the American Society of Parenteral and Enteral Nutrition (ASPEN). A survey was distributed to member organizations participating in the NOVEL project. Respondents were also asked if and when a change in practice occurred in the policy for NGT placement verification, if there was variation within the institutional units and if there were barriers to practice change. Findings Respondents were primarily nurses (205/245) from 166 institutions that provided care to combined adult/pediatric/neonatal (122/166) patients. Respondents indicated a radiograph (64%) or pH measurement (24%) were best practice but in actual practice 42% use pH measurement and 23% use a radiograph to verify NGT placement. There was variability within institutions, with the Neonatal Intensive Care Unit (NICU) most often using aspiration and direct eye visualization to verify placement and the other units within the institutions using EBP method(s). Discussion Comparing these results to previous work by the NOVEL project shows an increase toward the use of EBP method(s) to verify NGT placement verification. Application to practice This study demonstrates variation within units at the same facility using methods unsupported by the literature, demonstrating that many centers still rely on non-EBP methods of NG placement confirmation, despite cautions issued by many major healthcare organizations.

Although there is increased uptake of active learning approaches in especially developed countries, this is still lagging within the African context. The current study therefore focused on the implementation of group learning at Stellenbosch University, with several modifications versus our earlier, pilot study. Students freely formed small groups at the start of a 5-wk cardiovascular physiology lecture series and were apportioned three separate assignments to complete over this period. This included three in-class group-learning sessions, while students also completed group work outside class times. The active learning element was embedded within a constructive alignment framework. Our data revealed that 75% of the students felt that the in-class sessions was a good use of their time and that they progressively improved their assignment scores, i.e., 67.5 ± 9.3%, 72.4 ± 9.8%, and 76.1 ± 9.5% for the first, second, and final ones, respectively ( P < 0.0001). Moreover, the average class score for their final test (68 ± 15.1%) was higher when compared with the average class score (57.5 ± 19.4%) calculated for the previous 3 yr ( P < 0.0001). This study revealed two major findings: i.e., 1) students displayed a strong positive response regarding the adoption of in-class collaborative group work, and 2) the introduction of such active learning elements correlated with improved student assignment and test scores. Based on these findings, we propose additional modifications (including a shift to more formative assessments) to ensure even greater success with the roll-out of such active learning elements within the African context.

This study explored the course of health state utility value over 3 years in patients with a recent fracture attending a Fracture Liaison Service and suggested that the overall change in health-related quality of life was not significant, although significant improvements were observed at 6 and 12 months compared to baseline. Introduction To estimate the 3-year health-related quality of life (HRQoL) of patients with a recent fracture presenting at a Fracture Liaison Service (FLS) and to explore factors associated with health state utility value (HSUV). Methods Patients' HSUVs were derived from the EQ-5D-5L and SF-6D and calculated at six time points. Multiple imputation was applied for missing data. Linear mixed-effects regression analysis with random intercept and slope was applied to explore the course of HSUV over 3 years. The impact of subsequent fracture and the length of time between FLS visit and patients' index fracture on HSUV were also investigated. A backward stepwise elimination was applied to identify factors associated with HSUV. Results A total of 499 patients were included. The change of EQ-5D HSUV was not significant over 3-year follow-up (P = 0.52), although slightly but significantly higher HSUV was captured at 6 months (mean difference (MD): 0.015, P = 0.02) and 12 months (MD: 0.018, P = 0.01). There was no significant difference in the course of EQ-5D HSUV between fracture locations (P = 0.86). A significant increase in HSUV was only captured for patients had shorter time period (< 107 days) between FLS visit and their index fracture. Suffering a subsequent fracture was associated with significant QoL loss (MD: - 0.078, P < 0.001). Subsequent fracture, previous treatment with anti-osteoporosis medication, a prevalent vertebral fracture (grade 2 or 3), use of a walking aid, previous falls, and higher BMI were negatively associated with mean EQ-5D HSUV over 3 years. Comparable results were found using SF-6D HSUV. The lack of HRQoL data immediately after fracture and selection bias were two main limitations. Conclusion The 3-year change in HSUV was not statistically significant, although significant improvements were observed at 6 and 12 months in comparison with baseline. Six factors were negatively associated with EQ-5D HSUV. China Scholarship CouncilChina Scholarship Council [201909110080]

Objective To describe adult outcome of people with attention-deficit/hyperactivity disorder (ADHD) diagnosed in childhood and its several key predictors via a review of 7 North American controlled prospective follow-up studies: Montreal, New York, Milwaukee, Pittsburgh, Massachusetts General Hospital (MGH), Berkeley, and 7-site Multimodal Treatment Study of Children With ADHD (MTA). Method All studies were prospective and followed children with a diagnosis of ADHD and an age- and gender-matched control group at regular intervals from childhood (6–12 years of age) through adolescence into adulthood (20–40 years of age), evaluating symptom and syndrome persistence, functional outcomes, and predictors of these outcomes. Results The rates of ADHD syndrome persistence ranged from 5.7% to 77%, likely owing to varying diagnostic criteria and the source of information (self-report vs informant report) across the studies. However, all studies observed high rates of symptomatic persistence ranging from 60% to 86%. The 7 studies were largely consistent in finding that relative to control groups, research participants with childhood-diagnosed ADHD had significant impairments in the areas of educational functioning, occupational functioning, mental health, and physical health as well as higher rates of substance misuse, antisocial behavior, and unsafe driving. The most consistently observed predictors of functional outcomes included ADHD persistence and comorbidity, especially with disruptive behavior disorders. Conclusion Childhood ADHD has high rates of symptomatic persistence, which is associated with negative functional outcomes. Characteristics that predict these negative outcomes, such as comorbid disruptive behavior disorders, may be important targets for intervention.

Cel pracyW literaturze przedmiotu rzadko spotyka się badania nad predyktorami przebiegu schizofrenii młodzieńczej, zwłaszcza oparte na danych pochodzących z długoterminowych katamnez.

AIM This prospective cohort study aimed to investigate whether orthodontic appliances removal (OAR) combined with caries-preventive strategies and fluoride varnishes alters salivary physicochemical properties, changes the activity of carbonic anhydrase VI (CA VIACT ) and α-amylase (α-AMLACT ), and favors the regression of active carious lesions (ACL). DESIGN Twenty-two individuals aged between 13 and 24 years old were assessed for the presence of visible biofilm, daily sugar exposure, caries activity, salivary flow rate (SFR), pH, buffering capacity (BC), and CA VIACT and α-AMLACT activity at baseline, and 1, 5 and 13 weeks after OAR. Variables were assessed using repeated-measures analysis of variance, Cochran's Q and McNemar's test, and Pearson's correlation. RESULTS We verified a significant decrease in the number of ACL at the 5-week (29% reduction) and at the 13-week follow-up (58% reduction). At the 5 and 13-week follow-up, the percentage of visible biofilm and sugar exposure decreased, whereas the salivary pH and α-AMLACT activity significantly increased. BC and CA VIACT remained unchanged throughout the follow-up. CONCLUSION OAR combined with caries-preventive strategies and fluoride varnishes favored the regression of active carious lesions and increased salivary pH and α-AMLACT activity, whereas buffering capacity and CA VIACT remained stable.

Mitochondrial DNA copy number (mtDNA-CN) is a surrogate biomarker of mitochondrial dysfunction and is associated with type 2 diabetes (T2D) and cardiovascular disease (CVD). However, despite being associated with both CVD and T2D, it is not known what role mtDNA-CN has in the association between T2D and CVD. Our aims were to investigate whether, (1) baseline mtDNA-CN is associated with CVD incidence and (2) mtDNA-CN has a role as a mediator between T2D and CVD.We quantified absolute mtDNA-CN by droplet digital PCR method in a population-based follow-up study of middle aged (52-65 years) women (n = 3062). The median follow-up period was 17 years.Our results show that low baseline levels of mtDNA-CN (111 copies/μL) were associated with an increased risk of CVD (HR = 1.32, 95% CI = 1.08; 1.63) as well as with specific CVDs: coronary heart disease (HR = 1.28, 95% CI = 0.99; 1.66), stroke (HR = 1.26, 95% CI = 0.87; 1.84) and abdominal aortic aneurysm (HR = 2.61, 95% CI = 1.03; 6.62). The associations decreased but persisted even after adjustment for potential confounders. Furthermore, our results show that the total effect of T2D on future risk of CVD was reduced after controlling for mtDNA-CN and the proportion mediated by mtDNA-CN was estimated to be 4.9%.Lower baseline mtDNA-CN is associated with incident CVD and may have a mediating effect on the association between T2D and CVD; however, this novel observation needs to be confirmed in future studies.

Objectives: To evaluate the experienced barriers of care for treatment-seeking trans individuals (TSTG) in three large European clinics. Methods: An online follow-up questionnaire was filled out by 307 TSTG individuals as part of the research protocol of the European Network for the Investigation of Gender Incongruence (ENIGI). Data was collected during follow-up in 2017/2018, around 5 years after participants had their initial clinical appointments in Ghent (Belgium), Amsterdam (the Netherlands), or Hamburg (Germany). Background characteristics, country, treatment characteristics and mental health were analyzed in relation to experienced barriers of care (EBOC, measured though agreement with statements). Results: The majority of participants reported various EBOC, oftentimes more than one. The most-frequently reported EBOCs pertained to the lack of family and friends’ support (28.7%, n = 88) and travel time and costs (27.7%, n = 85), whereas around one-fifth felt hindered by treatment protocols. Also, a significant share expressed the feeling that they had to convince their provider they needed care and/or express their wish in such way to increase their likelihood of receiving care. A higher number of EBOCs reported was associated with more mental health problems, lower income and female gender. Conclusions: A substantial number of TSTG individuals within three European health care systems experiences EBOCs. EBOCs relate to both personal and systemic characteristics. These findings can help health care providers and centers to improve care. More research must be done to better understand the diversity among TSTG individuals and the corresponding barriers experienced.

OBJECTIVE EnPlace™ (formerly named NeuGuide™) is a minimally invasive meshless anchoring system for pelvic organ prolapse (POP) repair designed to provide centro-apical pelvic floor support. We present a 4-year prospective follow up evaluation of this repair system. METHODS This was a single-center longitudinal prospective study of women with advanced POP who underwent pelvic floor apical repair using EnPlace™ with at least four years of follow-up. The primary outcome was surgical success defined as anatomical success, no symptoms of vaginal bulging and no need for re-treatment. A standardized validated questionnaire to assess symptom burden was used. RESULTS Fifteen women were enrolled to the study. Two patients were lost to follow-up. The median follow-up was 51 months (range 42-57) with a surgical success rate of 92.3%. %. 1 patient (7.7%) reported symptoms of vaginal vault prolapse, and underwent a repeated prolapse surgery. Using the UDI-6 questionnaire, an improvement in all domains was seen. CONCLUSIONS The 4-year prospective follow up suggests that apical repair using the EnPlace ™ device may be considered safe and effective for sacrospinous ligament fixation with a sustainable long-term success. This procedure is a minimally invasive meshless addition to pelvic surgeon's armamentarium.

The aim of this study was to assess the changes in vital salivary parameters such as calcium, phosphorous, alkaline phosphatase, buffering capacity, pH, flow-rate and Oral Hygiene Index (OHI) in fixed orthodontic treatment patients during the retention period. In this study, saliva samples were collected from 35 patients before de-bonding (T0) and after 4 to 5 weeks of de-bonding or on retention period (T1). The biochemical parameters such as calcium, phosphorous and alkaline phosphatase levels were measured with saliva samples. Additionally, flow-rate, buffering capacity, pH and OHI levels was also measured. The current study results showed reduction in calcium, alkaline phosphatase, pH, flow-rate and OHI levels during T1 (p

Purpose To observe the long-term postoperative bone formation and eruption of adjacent teeth after octacalcium phosphate granule and atelocollagen complex (OCP/Col) grafting in the treatment of alveolar cleft of patients with unilateral cleft lip with or without cleft palate (UCL ± P). Methods Four patients with UCL ± P who underwent OCP/Col grafting (OCP group), and 55 patients with UCL ± P who underwent autologous bone grafting (AB group) were enrolled in this study. OCP/Col or autologous bone grafting was performed before the eruption of canines or lateral incisors in mixed dentition, followed by orthodontic management. Patients in the OCP group underwent radiography before and after surgery at 1, 2, 3, 6, and over 30 months postoperatively. The volume and area of the bony defect in the alveolar cleft area were compared between the OCP and AB groups before and after 6 months of surgery. Results The bone bridge in all patients in the OCP/Col group was successfully formed, and by 6 months postoperatively, the permanent teeth adjacent to the alveolar cleft had erupted at the site of the OCP/Col complex graft. Comparison of the pre- and postoperative bone defects between the 2 groups revealed almost the same extent of bone bridge formation. Conclusions OCP/Col grafting could be considered as an alternative to autologous bone grafting as it yielded successful bone bridge formation and facilitated permanent tooth eruption.

Background: Rickets is a disorder of defective mineralization due to deficiency of calcium and vitamin D and is more prevalent amongst the developing nations. Rickets has been ranked amongst the five most prevalent diseases in children of developing countries. The diagnosis of rickets is based on clinical features, biochemical studies and radiological signs and confirmed by response to treatment. Aims and Objectives: The purpose of this study is to evaluate the clinical, radiological and biochemical markers of the rickets by measuring the markers at the time of presentation, at 6 weekly intervals and after completion of treatment with standard regimen for rickets. Materials and Methods: 101 cases of nutritional rickets in age group 6 month to 18 years were allocated to receive combination therapy of calcium and vitamin-D according to their age and weight during a study period of 24 weeks. Radiographs (wrist and knee) and biochemical parameters (serum calcium, inorganic phosphate, alkaline phosphatase [ALP], and Vitamin-D), as well as clinical features, were evaluated at presentation, 6, 12, 18, and 24 weeks and response of treatment and markers were assessed at subsequent interval. clinical, radiological, biochemical parameters were evaluated statistically with Chi-square test for qualitative and 2 or more different variables by ANOVAs respectively. A P

Unintended pregnancy, as a pregnancy that is mistimed, unplanned or unwanted at the time of conception, is a common experience worldwide that puts mothers at risk for mental stress and its pregnancy complications. The aim of this study was to compare three common pregnancy complications, including preeclampsia, preterm labor, and low birth weight, between unintended and intended pregnancies in Sabzevar, northeast Iran in 2019.This prospective follow-up study was conducted on 200 pregnant women (100 intended and 100 unintended pregnancies) who were between 18 and 35 years old and were referred for delivery to Shahidan Mobini Hospital, Sabzevar, Iran. Data were collected using a questionnaire and the subjects were recruited based on inclusion and exclusion criteria. Preeclampsia, preterm labor, and low birth weight were recorded after delivery and were statistically analyzed using the statistical package for social sciences (SPSS software) version 22 at the statistical significance of0.05.The mean age and gravidity was significantly higher in the unintended pregnancy group compared to intended pregnancy group. The most common complication overall was low birth weight (25% of unintended and 16% of the intended pregnancies) followed by preterm labor (12% of unintended and 11% of intended pregnancies) and preeclampsia (5% of unintended and 1% of intended pregnancies). No significant relationship was found between the time of delivery and type of pregnancy (P = 0.50).The findings of this study indicated that unintended pregnancy can be a risk factor for pregnancy complications including preeclampsia and low birth weight and that sophisticated monitoring should be performed for better management of these complications.

Aim: The aim of this study was to explore the narratives of former substance use disorder (SUD) inpatients about substance use after their discharge from long-term SUD treatment in 2017. Method: We conducted semi-structured in-depth interviews with 11 former inpatients of SUD treatment. The data were analysed using a qualitative, thematic analysis model. Findings: During the analysis, two main themes emerged pertaining to participant reflections on substance use – their experience of non-problematic substance use (that is, substance use without declining into pre-treatment levels of misuse behaviours) and problematic substance use (that is, substance use associated with destructive patterns). All participants except one had engaged in substance use after their discharge three to four years ago. The commonly used substance was alcohol, which also appeared to be the most common substance for which there was consensus among the informants regarding non-problematic use. Conclusions: Most of the participants continued to use substances in some way, and some reported that such use did not affect them negatively. Healthcare providers and therapists in SUD treatment should avoid defining a relapse or failed treatment outcome in concrete terms. What is perceived as an actual relapse or a failed treatment outcome is highly subjective. Furthermore, complete sobriety might not necessarily be the best or the only way to measure the SUD treatment stay. An improvement in the quality of life and well-being, even when core symptoms are still present, may be considered a successful treatment outcome.

PURPOSE To update the incidence of uveitis in a Midwestern U.S. county population. METHODS Retrospective population-based cohort study. All Olmsted County, Minnesota residents diagnosed with uveitis from January 1, 2006 to December 31, 2015 were identified via the Rochester Epidemiology Project. Diagnoses were confirmed by a uveitis specialist. RESULTS There were 371 incident uveitis cases, yielding an overall age- and sex-adjusted incidence rate of 26.9 per 100,000 per year (95% CI: 24.1-29.7). Females accounted for 202 (54.4%) cases, 306 (82.5%) were White, and 299 (80.6%) were anterior uveitis. Highest incidence was observed in patients ≥65 years old. No difference in incidence existed between sexes (p = .17). Incidence rates increased with age for uveitis overall (all anatomic subtypes) (p

Cells exposed to ionizing radiation have a wide spectrum of DNA lesions that include DNA single-strand breaks, DNA double-strand breaks (DSBs), oxidative base damage and DNA-protein crosslinks. Among them, DSB is the most critical lesion, which when mis-repaired leads to unstable and stable chromosome aberrations. Currently, chromosome aberration analysis is the preferred method for biological monitoring of radiation-exposed humans. Stable chromosome aberrations, such as inversions and balanced translocations, persist in the peripheral blood lymphocytes of radiation-exposed humans for several years and, therefore, are potentially useful tools to prognosticate the health risks of radiation exposure, particularly in the hematopoietic system. In this review, we summarize the cytogenetic follow-up studies performed by REAC/TS (Radiation Emergency Assistance Center/Training site, Oak Ridge, USA) on humans exposed to internal and external radiation. In the light of our observations as well as the data existing in the literature, this review attempts to highlight the importance of follow-up studies for predicting the extent of genomic instability and its impact on delayed health risks in radiation-exposed victims.

Objective To study the impact of cardiovascular diseases (CVDs) on hearing deterioration among ageing adults in a longitudinal setting. Furthermore, to describe the pure tone threshold changes at the 0.125-8 kHz frequency range over 13 years. Design A population-based follow-up study. Study sample A random sample of 850 adults, of whom 559 participated in the follow-up study. Otological examination, a structured interview, and pure tone audiometry were conducted. Multivariate regression models were used to estimate the effect of CVD (participants had at least one cardiovascular condition) on hearing deterioration of the better ear hearing level (BEHL), defined as a change in the pure-tone average (PTA) of the frequencies 0.5, 1, 2, and 4 kHz and separately at the lower (0.125, 0.25, and 0.5 kHz) and higher (4, 6, and 8 kHz) frequencies. Results In the multivariable-adjusted analysis, the BEHL change at 13 years was 0.7 dB greater among participants with CVD (p = 0.3). The mean BEHL change during the 13-year follow-up was 12.0 dB (95% CI 11.4-12.6) among all participants. Conclusions No significant association between CVD and hearing threshold changes was found.

BACKGROUND: More than 7000 patients developed poliomyelitis during the main epidemic in the fifties in Israel. In recent years, there is a further deterioration in their condition due to accelerated aging process and post-polio syndrome. OBJECTIVE: To evaluate the risk factors for the progression of functional status in a cohort of patients with late effect of poliomyelitis over a period of ten years. METHODS: A cross-sectional cohort study including 82 individuals with late effect of poliomyelitis evaluated over ten years. Mean age was 67±8.5 years, 52.4%were men and 79.3%were Jewish. Functional status was evaluated by activities of daily living (ADL) questionnaire. Risk factors, including general comorbidities, history of poliomyelitis infection, use of assistive devices, employment, and physical activity statuses were evaluated using specific questionnaires. RESULTS: Independence in ADL functions deteriorated significantly over ten years. Older age, ethnicity, use of a wheelchair, and use of orthotic devices in childhood were risk factors for deterioration in ADL function. No correlation was found between the presence of other comorbidities or poliomyelitis parameters and worsening of ADL functions. CONCLUSIONS: Late effect of poliomyelitis was associated with deterioration in ADL functions probably due to the combined effect of the initial severity of the paralytic poliomyelitis symptoms and accelerated aging.

Introduction. The comparative effect of new-onset diabetes mellitus (DM) and hypertension (HT) on long-term mortality is a matter of debate. Materials and Methods. From 2007 to 2017, a 10-year longitudinal retrospective cohort study was conducted in Thailand’s tertiary care setting. As baseline data, health check-up data from apparently healthy participants without underlying disease from 2007 were extracted. The vital status of all participants was determined in 2017, ten years after an initial examination. The impact of new-onset DM and HT at baseline on 10-year all-cause mortality was investigated using multivariable logistic regression analysis. Results. The prevalence of new-onset DM and HT was 6.4% and 28.8%, respectively, at baseline. Newly diagnosed diabetes increased the risk of all-cause mortality over 10 years (adjusted OR 4.77 and 95% CI 2.23-9.99). HT, on the other hand, did not increase the risk of death (adjusted OR 1.24 and 95% CI 0.65-2.35). Different HT and DM status combinations were compared to a nondiabetic, nonhypertensive reference. Individuals who were diabetic and hypertensive had a greater risk of death (adjusted OR 6.22 and 95% CI 2.22-17.00). Having DM without HT also increased the risk of death (adjusted OR 4.36 and 95% CI 1.35-12.87). However, having HT without DM did not result in a significant increase in 10-year mortality risk (adjusted OR 1.21 and 95% CI 0.57-2.56). Conclusion. In an apparently healthy population, new-onset DM is more strongly associated with 10-year all-cause mortality than new-onset HT. Having both DM and HT was associated with a greater risk of death when compared to having DM or HT alone.

Background Multiple sclerosis (MS) is an autoimmune disease that attacks the central nervous system, with optic neuritis (ON) being a common early manifestation. Retinal nerve fiber layer (RNFL) thickness may be a biomarker of neuroaxonal damage in MS patients. We sought to evaluate changes in RNFL thickness over 4 years in Omani MS patients with or without ON in comparison to a healthy control group. Methods This retrospective case-control study involved 27 MS patients and 25 healthy controls. Optical coherence tomography was performed upon first diagnosis and at a four-year follow-up. Differences in mean RNFL thickness were calculated. Results A total of 51 eyes from the MS group and 50 eyes from the control group were evaluated. There was a significant reduction in mean RNFL thickness among MS patients with ON at follow-up (81.21 versus 72.14 μm; P = .003), whereas no significant RNFL thinning was observed among MS patients without ON. However, there was a significant reduction in RNFL thickness among MS patients compared to healthy controls (76.79 versus 93.72 μm; P = .009), regardless of ON presence/absence. Conclusions Axonal damage was seen in the optic nerves of Omani MS patients. Moreover, there was a significant reduction in RNFL thickness among MS patients with ON as the disease progressed; however, while there was evidence of RNFL thinning in MS patients without ON, this difference lacked statistical significance. Evaluation of RNFL thickness may represent a useful biomarker for monitoring disease progression in MS and its association with ON.

This study aimed to compare the changes in the salivary cariogenic bacteria levels using qPCR and oral hygiene status after orthodontic treatment with fixed appliances during the retention phase concerning the patient and treatment variables. In this study, saliva samples were collected from 35 patients before debonding (T0) and after five weeks of debonding on retention (T1). The saliva samples were collected to extract the genomic DNA, and using specific probes and primers using real-time polymerase chain reaction was performed to analyze the changes in S. mutants, S. sobrinus, L. Casei after orthodontic treatment with fixed appliances. Additionally, OHI levels were also measured. The current study confirms the statistical association between T0 and T1 groups of S. mutants (p = 0.028) and S. sobrinus (p = 0.049). However, a lack of association was observed with L. Casei (p > 0.05). The number of bacteria was decreased from the T0 group and increased in the T1 group in Streptococcus mutants (S. mutants) and Streptococcus Sobrinus (S. sobrinus) while in Lactobacillus Casei (L. Casei) it was vice versa between T0 and T1 groups. The Oral Hygiene Levels (OHI) levels were also found to be statistically associated (p = 0.003). This study concludes that comparing the salivary cariogenic bacterial levels at T0 (before debonding of fixed orthodontic appliances), with T1 (Five weeks after the debonding), and despite better oral hygiene, there was increase in salivary S mutants and S sobrinus levels. The current study suggested that orthodontic patients need careful hygienic procedures during the retention period. Future studies are recommended with additional follow-up and a large sample size.

In recent years, transition-metal-catalyzed C–H functionalization has emerged as a potentially greener alternative to classic cross-couplings and as a powerful tool to access complex functional molecules with improved step-economy. This short account relates our experience of industrial collaborations in C(sp3)–H bond activation, which were key to the development of this topic in our group. The synthesis of the antianginal drug Ivabradine led us to develop a general approach to benzocyclobutenes, which were further employed in pericyclic reactions. A follow-up study led us to discover a new method to construct arylcyclopropanes via double C–H activation and the coupling of two alkyl groups. Finally, targeting the herbicide Indaziflam contributed to develop C(sp3)–H activation as a powerful tool to access a variety of relevant indane motifs. We hope that these successful stories will help to stimulate further fruitful Industry-Academia collaborations in the field of synthetic chemistry.

Context Nationwide data on children diagnosed with craniopharyngioma (CP) are not available in Italy. Objective This work aimed to identify patients’ characteristics, type of surgical approach, complications and recurrences, number of pituitary deficits, and number of patients starting growth hormone (GH) treatment. Methods A retrospective multicenter collection took place of 145 patients aged 0 to 18 years who underwent surgery for CP between 2000 and 2018, and followed up in 17 Italian centers of pediatric endocrinology. Results Age at diagnosis was 8.4 ± 4.1 years. Duration of symptoms was 10.8 ± 12.5 months and headache was most frequent (54%), followed by impaired growth (48%) and visual disturbances (44%). Most lesions were suprasellar (85%), and histology was adamantinomatous in all cases but two. Surgical approach was transcranial (TC) in 67.5% of cases and transsphenoidal (TS) in 31.%. The TC approach was prevalent in all age groups. Postsurgery complications occurred in 53% of cases, with water-electrolyte disturbances most frequent. Radiotherapy was used in 39% of cases. All patients but one presented with at least one hormone pituitary deficiency, with thyrotropin deficiency most frequent (98.3%), followed by adrenocorticotropin (96.8%), arginine vasopressin (91.1%), and GH (77.4%). Body mass index (BMI) significantly increased over time. A hypothalamic disturbance was present in 55% of cases. GH therapy was started during follow-up in 112 patients at a mean age of 10.6 years, and 54 developed a recurrence or regrowth of the residual lesion. Conclusion CP is often diagnosed late in Italy, with TC more frequent than the TS surgical approach. Postsurgery complications were not rare, and hypopituitarism developed almost in all cases. BMI shows a tendency to increase overtime.

This research was conducted to determine the relationship of Science teachers’ teaching styles and the students’ learning styles and academic performance. The study was conducted among the public secondary school in Subic, Zambales during the academic year 2018 – 2019. The descriptive survey research design was used where the teaching styles of eighty-five teachers and six hundred high school students. Data were analyzed using the percentage, mean and chi square test. The findings of the study revealed that the science teachers are adults with the most of them are female. The students are teenagers mostly male in Grade 8. The teaching styles of the science teachers is of a formal authority and the learning styles of the students is generally visual. The academic performance in science is satisfactory. The teaching styles of the teachers was dependent on education, field of specialization, length of service. The learning styles of the students were not dependent significantly on their age and year level. The learning styles of the students were significantly dependent on teaching styles of their science teachers and the academic performance of the students significantly dependent on the teaching styles of the science teachers. The academic performance of students are significantly dependent on their learning styles. With these findings and conclusions follow up studies exploring other factors affecting the performance level of the students in Science is recommended as well as the effectiveness of the various teaching styles and learning styles to promote learning and better understanding in the subject must be conducted.

Although paraphilic interests represent significant risk factors for recidivism among sexual offenders, little is known about the magnitude of concordance between paraphilic interests and behaviors in the general population. The goal of this follow-up study was to conduct secondary analyses based on a sample of 1040 adults (475 men; 565 women) recruited in the general population. Levels of associations and active concordance (having both interest and experience), passive concordance (having neither interest nor experience), active discordance (having experience without interest) and passive discordance (having interest without experience) between paraphilic interest and corresponding behavior were assessed. Concordance and discordance indexes were also computed, as well as regressions and moderation analyses. As expected, paraphilic interests predicted corresponding behaviors, although the mean active concordance rate was only approximately 50%. Concordance rates varied with gender and the criminal nature (legal vs. illegal) of paraphilia. Paraphilic interests in adults from the general population may not have the same predictive value as that observed in medico-legal contexts. The possible role of other moderators in the concordance between paraphilic interest and behavior in non-clinical populations should be assessed. These findings have implications for sexual abuse prevention programs aiming at individuals in the community.

IntroductionSeclusion still occurs on mental health wards, despite absence of therapeutic efficacy and high risks of adverse patient effects. Literature on the effect of nursing teams, and the role of psychological characteristics in particular, on frequency of seclusion is scarce.AimTo explore the influence of demographic, professional or psychological, nursing team-level, and shift characteristics on the frequency of use of seclusion.MethodsProspective two-year follow-up study.ResultsWe found that the probability of seclusion was lower when nursing teams with at least 75% males were on duty, compared to female only teams, odds ratio (OR = 0.283; 95% CrI 0.046–0.811). We observed a trend indicating that teams scoring higher on the openness personality dimension secluded less, (OR = 0.636; 95% CrI 0.292–1.156).DiscussionHigher proportions of male nurses in teams on duty were associated with lower likelihood of seclusion. We found an indication that teams with a higher mean openness personality trait tended to seclude less. These findings, if causal, could serve as an incentive to reflect on staff mix if circumstances demand better prevention of seclusion.
