Stress fractures, including both fatigue and insufficiency types, are frequently encountered in clinical practice as a source of pain in a variety of patients (athletes, older patients, and patients with predisposing conditions). Radiography is the imaging modality of choice for baseline diagnosis. MRI has greatly improved our ability to diagnose radiographically occult stress fractures. Nuclear medicine scintigraphy and CT may also be useful as diagnostic tools. Although fatigue and insufficiency fractures can be self-limited and go on to healing even without diagnosis, there is usually value in initiating prompt therapeutic measures as incomplete stress fractures have the potential to progress to completion, necessitating surgery. This is particularly important in the setting of stress fractures of the femoral neck. Accuracy in the identification of these injuries is also relevant because the differential diagnosis includes entities that would otherwise be treated differently (ie, metastatic disease). The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision process support the systematic analysis of the medical literature from peer reviewed journals. Established methodology principles such as Grading of Recommendations Assessment, Development, and Evaluation or GRADE are adapted to evaluate the evidence. The RAND/UCLA Appropriateness Method User Manual provides the methodology to determine the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where peer reviewed literature is lacking or equivocal, experts may be the primary evidentiary source available to formulate a recommendation. [ABSTRACT FROM AUTHOR]

Aim Methods Results Conclusion This study aimed to evaluate papers analysing dietary intake, 25‐hydroxyvitamin D (25(OH)D) concentrations and anthropometry in children on vegetarian, vegan and omnivorous diets, as research indicates all diets generally fall below recommended vitamin D intake.This mini review examined the vitamin D status of children aged 1–18 years by systematically searching PubMed, Google Scholar and Scopus databases from January 1, 2000, to December 31, 2023.The review included nine studies published between 2000 and 2023. Four studies reported lower vitamin D intake in children on vegetarian and vegan diets compared to omnivores. Three studies reported lower 25(OH)D concentrations in children on vegetarian and vegan diets. Specifically, one study found lower concentrations in vegans compared to omnivores, another found lower concentrations in vegetarians and vegans not taking supplements and a third reported lower 25(OH)D concentrations in Asian children aged 3–4.5 years compared to Caucasian children. Three studies found no significant differences in 25(OH)D between diet groups. Three studies assessing anthropometry showed that vegetarians have similar body weight and height as omnivores.Children across all dietary groups may have low vitamin D intakes; supplementation should be considered for those with inadequate sun exposure, especially those avoiding animal products.

Abstract Background Vitamin D insufficiency (25OHD, 50–75 nmolˑl− 1) is a common issue within healthy adults and elite athletes and is associated with decreased musculoskeletal health and performance. However, few studies have identified the prevalence and risk factors associated with vitamin D insufficiency within elite Para-Athletes. Methods An electronic search was completed on the 5th January 2023 and updated on the 21st June 2024, searching Web of Science, PubMed, Scopus, Cochrane Library and EASY (originally OpenGrey). To meet the eligibility criteria, retrieved studies were required to include at least one baseline measure of a vitamin D biomarker from elite Para-Athletes performing at national or international levels and therefore all quantitative study designs could be included. Risk of bias was assessed using the Joanna Briggs Institute Critical Appraisal Checklist (8-item) for analytical cross-sectional studies. Data from the eligible studies was extracted and charted, with a supporting narrative synthesis. Results The search strategy retrieved 3083 articles, of which ten studies met the inclusion criteria. In total there were n = 355 Para-Athletes, 69.6% of which comprised of males in the included studies. Across the ten included studies, n = 546 samples were taken from n = 355 Para-Athletes across different seasons and based upon the 25(OH)D insufficiency and deficiency thresholds set by each individual study 43.2% of the samples were considered insufficient and 28.1% deficient. During the winter months vitamin D insufficiency was at its most prevalent at 74.1%, compared to 57.1% in summer of the 25(OH)D samples measured in Para-Athletes. Wheelchair athletes who competed in indoor sports were also more susceptible to low vitamin D. Conclusion This review has highlighted that vitamin D insufficiency and deficiency is highly prevalent in elite level Para-Athletes, all year, across both summer and winter months. Therefore, this review highlights the need for education, treatment, and preventative measures in elite Para-Athletes throughout the year. Registration The following systematic review was prospectively registered through PROSPERO International prospective register of systematic reviews (PROSPERO registration ID number: CRD42022362149).

Abstract Background Vitamin D deficiency (VDD) is conventionally associated with inadequate sunlight exposure. Ironically, recent evidence suggests a rising prevalence in urban areas of tropical regions like Sri Lanka, where comprehensive data are unavailable. This study aimed to estimate the prevalence of low vitamin D status in urban adults and its impact on serum calcium. Methods A population-based cross-sectional study was conducted among 1260 adults aged 35–74 years, living in Colombo, the most urban district in Sri Lanka. They were recruited from 63 administrative divisions, using multi-stage, probability-proportionate-to-size, cluster sampling. Non-fasting venous blood was collected without tourniquet. Low vitamin D (

On March 20, 2024, an interdisciplinary meeting of the Expert Council on the current problem of B12 insufficiency/deficiency and the prevalence of this condition among endocrine patients was held at the Endocrinology Research Centre (Moscow). The purpose of the meeting was to assess the role of B12 deficiency in reducing the quality of life of patients of different groups and to outline a strategy for the management of patients with vitamin B12 insufficiency/deficiency by endocrinologists.The resolution of the expert council was developed by leading specialists in various specialties.

Objective: The relationship between spontaneous osteonecrosis of the knee (SONK) and ipsilateral meniscus tear remains to be established, and the possible causes are clarified and summarized. Methods: We conducted a search in Pubmed, Web of Science, Embase, and the Cochrane Library to include all English articles published from the establishment of the database until April 2023. The odds ratio (OR) and 95% confidence interval (CI) were calculated to evaluate the relationship between SONK and ipsilateral meniscus lesions. Results: A total of 405 patients were included in eight articles, including 157 males and 248 females, with an average age of 63.94 years and an average BMI of 26.36 kg/m2. In patients with medial SONK, the prevalence of ipsilateral meniscus tear was 0.8982, 95% CI (0.7389, 0.9648), and the prevalence of ipsilateral posterior root tear was 0.6198, 95% CI (0.5169, 0.7118). The prevalence of ipsilateral meniscus tears in patients with lateral SONK was 0.2188, 95% CI (0.1150, 0.3711), and the prevalence of ipsilateral posterior root tears was 0.1667, 95% CI (0.1071, 0.2424). Conclusions: SONK is significantly associated with meniscus or root tears, which limit meniscus function and lead to changes in the stress environment between the knee and the tibiofemur, increasing the chance of incomplete fracture. We suggest that the expression of SONK can be replaced with subchondral insufficiency fracture of the knee. [ABSTRACT FROM AUTHOR]

Background: Vitamin D deficiency (VDD) is conventionally associated with inadequate sunlight exposure. Ironically, recent evidence suggests a rising prevalence in urban areas of tropical regions like Sri Lanka, where comprehensive data are unavailable. This study aimed to estimate the prevalence of low vitamin D status in urban adults and its impact on serum calcium. Methods: A population-based cross-sectional study was conducted among 1260 adults aged 35–74 years, living in Colombo, the most urban district in Sri Lanka. They were recruited from 63 administrative divisions, using multi-stage, probability-proportionate-to-size, cluster sampling. Non-fasting venous blood was collected without tourniquet. Low vitamin D (< 30.0 ng/mL), VDD (< 20 ng/mL) and vitamin D insufficiency (20.0–29.9 ng/mL) were determined using chemiluminescence assay method, and serum calcium using Calcium Gen2 reagent. Results: Among the population (53.3% females; mean age = 51.8 years), the prevalence of low vitamin D was 93.9% (95% CI: 92.5–95.2). This was primarily due to VDD (67.5%; 95% CI: 64.9.0–70.1%), with some insufficiency (26.4%; 95% CI: 24.0–28.9%). Most VDD cases (53.9.0%) were 'mild' (10.0- < 20.0 ng/mL) in severity, with fewer 'moderate' (12.8%) and 'severe' (0.8%) cases. Prevalence of VDD was highest in females, aged 35–44-years, living in 'highly urban' areas and of Tamil ethnicity. Further, VDD showed a decreasing trend with older age groups, while it was significantly more prevalent in females than males (72.6% vs. 61.7%; p < 0.01), across all age groups. Low serum calcium levels were observed in 9.8% of adults with low vitamin D, compared to 22.4% with normal vitamin D, implying that there could be factors other than vitamin D in maintaining serum calcium levels. Conclusions: Colombo District, representing urban settings in Sri Lanka faces a high prevalence of low vitamin D, primarily VDD, with higher rates in females, younger individuals and highly urban areas. These findings challenge assumptions about tropical regions being guaranteed of optimal vitamin D levels; and underscore the need for national vitamin D supplementation and food fortification programs, especially in high-risk urban settings in South Asian countries like Sri Lanka.

Sacral fractures can cause lower urinary tract symptoms (LUTS) due to damage to the cauda equina. While several studies have reported on sacral fractures due to high-energy trauma, those due to fragility fractures have only been reported in case reports and their clinical differences are not well known. This study aimed to investigate the clinical characteristics of LUTS caused by fragility sacral fractures and propose a novel treatment strategy. This study is retrospective, uncontrolled, clinical case series. The inclusion criteria were sole sacral fractures due to low-energy trauma and appearance of LUTS after injury. Patients with additional spinal fractures or combined abdominal or pelvic organ injuries that could cause LUTS were excluded. Improvement in LUTS, period from onset to improvement, and imaging findings were recorded. Eight patients met the inclusion criteria (4 surgical and 4 conservative treatment cases). Six patients showed improvement in LUTS. In surgical cases, the mean period from onset of LUTS to surgery and from onset of LUTS to improvement was 14.5 and 21.5 days, respectively. Intraoperative rupture or laceration of the dural sac was not observed. In 2 conservatively improved cases, the period from onset to improvement of LUTS was 14 and 17 days. LUTS can improve even with conservative treatment and should be utilized as the primary choice. LUTS caused by severe sacral canal deformity and stenosis can be reversible, and the decision to perform surgical treatment is still timely if LUTS do not improve with conservative treatment for several weeks.

An adequate vitamin D level is essential for optimal bone mass formation during growth. The present study aimed to assess (i) the sex-specific, age-specific, and potential seasonal (spring, summer, winter) influences on the pediatric circulating levels of 25-hydroxyvitamin D (25(OH)D); (ii) determine the frequency of pediatric patients with vitamin D deficiency (VDD) or insufficiency (VDI); and (iii) quantify the association between age category, sex, and season types and susceptibility to VDD and VDI, respectively. Laboratory data were collected on serum 25(OH)D levels in children aged between 2 and 18 years (n = 1674) who underwent blood sampling following admission to a university pediatric hospital in Cluj-Napoca (Romania) between January and June 2023. VDD (<20 ng/mL) was observed in 27% of pediatric patients. Among toddlers and preschoolers (2–5 years), VDD was 11%, while it was 33% among school-aged children (6–11 years) and 39% among adolescents (12–18 years). We found a significant difference in the frequencies of vitamin D status between females and males (p = 0.006). Also, we found significant associations of vitamin D status with age categories (p < 0.0001) and seasonal variations (p = 0.03). After adjusting for season of blood collection, the multinomial logistic regression model showed that children aged 6–11 years old (adjusted OR = 7, 95% CI: (4.9, 9.4)), children aged 12–18 years old (adjusted OR = 14, 95% CI: (9.3, 19.6)), and females (adjusted OR = 1.43, 95% CI: (1.10, 1.86)) were significantly associated with higher odds of VDD. In conclusion, the study revealed a significant difference in the frequency of VDD and VDI among pediatric patients older than six years, with a significant difference according to sex and season, being more pronounced among girls and during the winter and spring seasons.

Abstract Vitamin D deficiency and insufficiency pose global public health challenges, yet research on serum vitamin D levels in the 0–17-year-old age group in southeastern China remains limited. This study aimed to fill this gap by investigating serum 25(OH)D levels in children in the region aged 0–17 years, contributing crucial data for understanding vitamin D nutritional status. Liquid chromatography‒mass spectrometry/mass spectrometry (LC‒MS/MS) technology was used. Vitamin D testing was integrated into routine diagnostic procedures for 11,116 children in Wujiang District, Suzhou City. Among the 0–17-year age group, comprising 6348 boys and 4768 girls, the prevalence of serum 25(OH)D deficiency and insufficiency was 21.4% and 31.0%, respectively. The median serum 25(OH)D concentration was 29.72 ng/mL (21.84–39.84 ng/mL) in boys compared to 28.48 ng/mL (20.65–39.23 ng/mL) in girls. Seasonal variations were observed, with median serum 25(OH)D concentrations of 29.02 ng/mL (20.73–39.72 ng/mL) in spring, 28.79 ng/mL (21.53–39.37 ng/mL) in summer, 30.12 ng/mL (22.00–39.70 ng/mL) in autumn, and 28.58 ng/mL (19.97–39.46 ng/mL) in winter. Statistically significant differences were noted in the serum 25(OH)D levels during autumn and winter. In conclusion, the rate of adequate vitamin D levels in local children was 47.5%, revealing a relatively high prevalence of vitamin D deficiency (21.4%) and insufficiency (31.0%), especially during the post-preschool period. Advocating for vitamin D supplementation in children is crucial for ensuring adequate vitamin D support.

Background: An optimal cobalamin status is necessary for normal neurodevelopment. Objective: To give a description of the epidemiology, pathophysiology and diagnostic challenges related to cobalamin insufficiency in neonates and infants in order to prevent its occurence. Results: Inadequate cobalamin status is prevalent among neonates and young infants, due to a high prevalence of maternal cobalamin deficiency, exclusive breastfeeding for extended periods and late introduction of animal food. Cobalamin insufficiency is associated with delayed neurodevelopment and subtle clinical symptoms like feeding difficulties, regurgitations and constipation in young infants. Early diagnosis and treatment of impaired cobalamin status is important to prevent neurologic damage. Conclusion: Clinical suspicion of cobalamin insufficiency in infants should infer immediate biochemical testing and a plasma total homocysteine > 5.0 µmol/L indicate cobalamin insufficiency in need of intramuscular treatment with hydroxycobalamin, followed by introduction of animal food after 4 months of age. Plain language title: Vitamin B12 Is Important for Normal Development in Young Children Plain language summary: Vitamin B12, also called cobalamin, is found only in animal-sourced food. As low-meat, vegetarian, and vegan diets are increasingly popular in Western countries, vitamin B12 deficiency has become common, also in pregnant women and babies. Vitamin B12 status is essential for normal development and adequate levels of this vitamin is particularly important during pregnancy and the first years of life. In pregnancy, vitamin B12 is transferred from the mother to the fetus, so the baby has a store of this vitamin at birth. However, if the mother has vitamin B12 deficiency or the baby is born premature or with a low birth weight, the vitamin store may be insufficient and the baby may develop vitamin B12 deficiency. Maternal vitamin B12 status is important as long as the baby is exclusively breastfed. Breast milk contains vitamin B12, but the concentration decreases after 4 to 6 weeks and may be too low to support the baby until animal-sourced foods are introduced. The vitamin B12 content in formula milk is higher than in breast milk, and vitamin B12 deficiency is more common in exclusively breastfed babies. Vitamin B12 deficiency is associated with diffuse symptoms in small babies and may be difficult to detect, and the diagnosis have a mean delay of 4 months in this age-group. Typical symptoms are regurgitations or spitting up, constipation, problems with feeding and swallowing, and delayed psychomotor development. Suspicion of vitamin B12 insufficiency in babies should prompt immediate biochemical testing. Plasma total homocysteine is a metabolic marker of vitamin B12 status and can be measured in a blood sample from the baby. A level >5.0 µmol/L indicates probable vitamin B12 insufficiency and the baby should receive vitamin B12 supplementation, followed by introduction of animal-sourced foods at 3 to 4 months of age.

Adequate vitamin D (VD) intake during pregnancy is needed for fetal development and maternal health maintenance. However, while there is no doubt regarding its importance, there is not a unified recommendation regarding adequate intake. The main aim of our study was to measure the VD serum level of studied women, together with its potential influencing factors: demographic (i.e., age, level of education, relationship status and type of residence), conception and pregnancy related factors. Results are based on secondary data analyses of a retrospective case–control study of 100 preterm and 200 term pregnancies, where case and control groups were analyzed together. Data collection was based on a self-administered questionnaire, health documentation, and maternal serum VD laboratory tests. VD intake was evaluated by diet and dietary supplement consumption. According to our results, 68.1% of women took some kind of prenatal vitamin, and only 25.9% of them knew about its VD content. Only 12.1% of included women reached the optimal, 75 nmol/L serum VD level. Higher maternal serum levels were associated with early pregnancy care visits (p = 0.001), assisted reproductive therapy (p = 0.028) and advice from gynecologists (p = 0.049). A correlation was found between VD intake and serum levels (p < 0.001). Despite the compulsory pregnancy counselling in Hungary, health consciousness, VD intake and serum levels remain below the recommendations. The role of healthcare professionals is crucial during pregnancy regarding micronutrients intake and the appropriate supplementation dose. [ABSTRACT FROM AUTHOR]

Introduction: As a result of the physiological decline in renal function that comes with age and the common failure to recognise renal insufficiency, older adults aged 65 and above are at increased risk of receiving medications that are inappropriate for their level of renal function which in turn lead to increased risk of adverse effects. Little is known about how many older adults receive medications that are inappropriate for their level of renal function. This study aimed to determine the prevalence of renally inappropriate medications in elderly adults by reviewing patient files and evaluating the appropriateness of medication doses relative to renal function in patients aged ≥ 65 years at inpatient healthcare departments. Methods: A retrospective cross-sectional study of patients aged ≥ 65 years was conducted, covering cases from 2015 to 2021. Patient's medical records were reviewed, their renal function and medications lists were evaluated, determined whether they had been prescribed at least one renally inappropriate medication based on drug-dosing recommendations for different degrees of renal function. Results: A total of 317 elderly inpatients were included, 10% of whom had received inappropriate doses relative to their renal function. Glomerular filtration rate was associated with inappropriate dosing in this study. Of the patients CKD stage 5, 36.8% had at least one drug administered at an inappropriate dose, while this figure was 6.5% among the patients at CKD stage 1; this difference was statistically significant (p = 0.001). Conclusion: A notable portion of older adults may be at risk of adverse effects due to inappropriate medication dosing related to their renal function. Further studies with large samples, drug use analyses based on comprehensive geriatric references and a prioritisation of actual outcomes over potential outcomes are needed to further determine elderly adults' exposure to inappropriate drugs.

Shame and the fear of shame can play highly significant roles for each participant in treatment. For example, the analyst may feel afraid that doing treatment will expose their insufficiencies as a clinician, and, even more broadly, as a human being. This paper discusses a number of varieties of the experience of shame, including those tinged with anger, guilt, and anxiety. It also examines the shame about feeling shame, which can be particularly troubling in training. Aspects of the candidate's position that may elicit shame are explored, with some suggestions about ways they could be ameliorated. [ABSTRACT FROM AUTHOR]

BackgroundHypovitaminosis D may be common in tropical countries and is linked to disorders of phospho-calcium metabolism, rickets, muscle pain, immune system deficiencies, and increased susceptibility to microbial infections.ObjectiveTo assess the prevalence of hypovitaminosis D in apparently healthy university workers in Loja, Ecuador.MethodsA cross-sectional study was completed in a private Ecuadorian university from May 2023 to September 2023, involving 440 participants. Data were gathered using a structured questionnaire created to assess risk factors influencing vitamin D levels. Serum 25-hydroxyvitamin D (25-OH)D concentrations were measured utilizing immunoenzymatic methods. Altered states (insufficiency or deficiency) of vitamin D were defined with serum values

Vitamin D plays an essential role in maintaining bone density, building the immune system, and regulating cell growth alongside other key biological functions. Limited data are available about the seasonal variation in vitamin D levels in the pediatric population in Saudi Arabia. This study aimed to investigate the seasonal influence on the pediatric circulating levels of 25(OH)D. A total of 1790 pediatric outpatients who visited the University healthcare centre were included in this study. Overall, there was a noticeably high prevalence (69%) of both combined 25(OH)D deficiency and insufficiency. The highest mean serum concentration of 25(OH)D was recorded in summer (29 ng/mL) and autumn (27 ng/mL). The deficient and insufficient categories were predominant, accounting for 33% and 36%, respectively. Comparable patterns were recorded during autumn, winter, and spring. Interestingly, the 25(OH)D level was significantly associated with the four seasons (p = 0.001), with females having a higher prevalence of 25(OH)D deficiency in the spring and summer than males. Furthermore, only in autumn and winter, we found a significant association between gender and 25(OH)D status (p < 0.001 for both). Another association between nationality and the circulating levels 25(OH)D was found during autumn and winter (p < 0.001 and p = 0.01), respectively. In all seasons, age had a negative impact on serum (OH)D levels. However, this relationship was statistically significant (p < 0.05) only in summer, autumn, and winter. Gender was a significant predictor, with 25(OH)D levels in autumn and winter and an odds ratio of 1.67 in autumn and 2 in winter, indicating that being men had a positive influence on circulating 25(OH)D levels. There were highly significant differences in 25(OH)D concentrations among different age categories. The Saudi population experiences low levels of vitamin D, particularly in autumn and winter periods. This study showed that seasonality, age category, nationality, and gender influence vitamin D status, suggesting the need for tailored intervention and monitoring of 25(OH)D status to reach adequate levels of vitamin D. Healthcare practitioners and policymakers may consider the interplay between age, nationality, gender, and seasonal variations when addressing vitamin D status and a targeted supplementation approach for high-risk groups that may develop health issues.

Background: Pre-presbyopes may suffer from ocular symptoms such as asthenopia of near work. Aim: This study aimed to evaluate near points of convergence, amplitudes of accommodation, and fusional vergence among pre-presbyopes with asthenopia symptoms. Setting: The study was conducted at El-Walidain Eye Hospital, Khartoum, Sudan in 2022. Methods: The study was a hospital-based prospective, including 107 pre-presbyopes aged 35–40 years who complained of asthenopia symptoms. Clinical examinations included an assessment of amplitude of accommodation, near point of convergence and fusional vergence. Results: The findings showed receded in near points of convergence and a decrease in the accommodation was highly significantly associated with increased age among emerging presbyopes with asthenopia symptoms (p = 0.0001). Conversely, positive and negative fusional vergence amplitudes were not significantly correlated with age with p = 0.109 and p = 0.355, respectively. Positive and negative fusional amplitudes were not significantly different between males and females (p ˃ 0.05). Esophoria was more common in pre-presbyopia 62 (57.4%) and exophoria 45 (43.6) with p = 0.503. Conclusion: The pre-presbyopes presented with low accommodation amplitude and receded near point of convergence, but without significant changes in positive and negative fusional vergence amplitudes. Contribution: This study added by demonstrating how early presbyopia altered accommodation amplitude and near point of convergence significantly while having no significant impact on amplitudes of positive and negative fusional vergence.

Abstract Background Vitamin D deficiency (VDD) is a public health problem. The variation in vitamin D status across regions and populations remains unclear, and there is a lack of consensus regarding the screening for VDD in individuals. Methods Children who visited the hospital from January 2019 to December 2020 were included in this study. Serum 25-hydroxyvitamin D (25(OH)D) concentrations were measured using an enzyme-linked immunosorbent assay. The cutoffs for serum 25(OH)D concentrations to define deficiency, insufficiency, and sufficiency were

Simple Summary: The early detection of pancreatic cancer is critical as it is usually too late for potentially curative surgical resection when obvious symptoms such as jaundice have developed. The pancreas has two main functions in the body, namely, an endocrine role, where it produces insulin to control blood glucose levels; and an exocrine role, where it produces enzymes that aid digestion. Impairment of this latter role is known as pancreatic exocrine insufficiency (PEI). It is an established feature of advanced pancreatic cancer, but it is unclear whether it is present in the early stages when surgery may still be an option. This study used two validated methods of testing pancreatic exocrine function, a breath test and a stool test, to demonstrate that exocrine insufficiency is associated with resectable pancreatic cancer. Pancreatic ductal adenocarcinoma (PDAC) is usually diagnosed late, leading to a high mortality rate. Early detection facilitates better treatment options. The aim of this UK-based case–control study was to determine whether two validated tests for pancreatic exocrine insufficiency (PEI), namely, the 13C-mixed triglyceride breath test (13C-MTGBT) and a faecal elastase (FE-1) test, can discriminate between patients with resectable PDAC versus healthy volunteers (HVs) along with a comparison group with chronic pancreatitis (CP). Discrimination between disease states and HVs was tested with receiver operator characteristic (ROC) curves. In total, 59 participants (23 PDAC (16 men), 24 HVs (13 men) and 12 CP (10 men)) were recruited, with a similar age in each population, and a combined median (IQR) age of 66 (57–71). The areas under the ROC curve for discriminating between PDAC and HVs were 0.83 (95% CI: 0.70–0.96) for the 13C-MTGBT, and 0.85 (95% CI: 0.75–0.95) for the FE-1 test. These were similar to CP vs. HV. In conclusion, PEI occurs in resectable PDAC to a similar extent as in CP; further large-scale, prospective studies using these tests in the primary care setting on high-risk groups are warranted.

Background: Sudden sensorineural hearing loss (SSNHL) is an autoimmune diseases of the inner ear which is usually defined by acute onset of hearing loss in one or both ears, of 30 dB or more on at least three contiguous audiometric frequencies within 3 days or less. This study aimed to compare the serum levels of 25-hydroxyvitamin D (VitD) between patients with SSNHL and healthy controls. Methods: A total of 50 patients with SSNHL and 50 healthy individuals without hearing loss as control group were enrolled in this study. Serum levels of VitD and other related laboratory tests such as calcium (Ca), phosphorus (P), and parathyroid hormone (PTH) were measured and compared between two study groups. Results: Serum level of VitD was significantly lower in patients suffering from SSNHL compared to the healthy controls (26.55 ± 14.44 vs. 33.51 ± 14.21, P = 0.017, respectively). VitD insufficiency was observed in 70% (n = 35) of the patients with SSNHL as compared to 44% (n = 22) of healthy individuals, demonstrating a significant difference between two study groups. However, no statistically difference was observed for serum levels of Ca, P, and PTH. Conclusion: This study indicated an increased prevalence of VitD insufficiency in subjects with SSNHL, suggesting a possible association between serum VitD levels and the development of SSNHL. VitD may protect the hearing loss through its antioxidant role. [ABSTRACT FROM AUTHOR]

Background: Vitamin D deficiency (VDD) is a public health problem. The variation in vitamin D status across regions and populations remains unclear, and there is a lack of consensus regarding the screening for VDD in individuals. Methods: Children who visited the hospital from January 2019 to December 2020 were included in this study. Serum 25-hydroxyvitamin D (25(OH)D) concentrations were measured using an enzyme-linked immunosorbent assay. The cutoffs for serum 25(OH)D concentrations to define deficiency, insufficiency, and sufficiency were < 20 ng/mL, 20–30 ng/mL, and ≥ 30 ng/mL, respectively. Results: A total of 7285 children aged 0–11 years were assessed; the mean 25(OH)D level was 31.4 ng/mL, and the median 25(OH)D level was 30.7 (interquartile range 24.4, 37.5) ng/mL. The 25(OH)D level declined with age in clinical visiting children aged 0–11 years, but maintained a consistently high level in health examination children aged 4–11 years. The percentages of 25(OH)D < 20 ng/mL and 25(OH)D < 30 ng/mL were 10.0% and 43.8%, respectively. Higher percentages of VDD were found in clinical visiting children than in health examination children within the 6–11-year group (53.3% vs. 14.7%) and winter (44.3% vs. 15.4%). Conclusion: Low vitamin D status (deficiency and insufficiency) was more common in clinic-visiting children than in health examinations, especially in schoolchildren and in the winter. The study implies the positive effects of vitamin D assessments included in child health checkups to optimize vitamin D status. [ABSTRACT FROM AUTHOR]

Relevance. Irrational nutrition of a pregnant woman, unjustified drug load, inactivity, insufficient insolation, constitute a high risk of vitamin D deficiency. Vitamin D deficiency conditions correlate with the frequency of the pathological course of pregnancy and childbirth, dictating the need for timely correction from the standpoint of optimizing care for the child population. The aim of the study - evaluation of the possibility of predicting vitamin D deficiency conditions in children in the antenatal period using a complex of medical and statistical analysis methods. Materials and Methods. A prospective cohort study of 248 mother-child pairs was conducted. Pregnant women: the main group (148) - receiving vitamin D prophylactically at a dose of 1000 MG (Aquadetrim) when registering. The comparison group was those who did not receive vitamin D (100). Inclusion criteria: absence of exacerbation of chronic pathology, allergic reactions, malabsorption syndrome, obesity, diabetes, taking HA, antiepileptic drugs, hyperparathyroidism, severe infections. All women were examined at the end of the 3rd trimester and the postpartum period. Children were observed of 248 children born to pregnant women of two groups. All children were observed with the informed consent of their parents. The duration of observation is up to 3 years. An assessment of the somatic status and general clinical examinations were carried out. Risk factors were assessed using mathematical and statistical methods to compile a prognostic scenario for the development of vitamin D deficient conditions. Results and discussion. Based on the data obtained using the statistical analysis method, it was found that the pathological course of pregnancy and childbirth in women who received vitamin D during pregnancy according to the RR data, AtR were significantly less frequent. Newborns of the main group had higher mass-growth indicators, significantly less often insufficiency, vitamin D deficiency, neurological symptoms; subsequently, a lower incidence of allergic diseases, acute respiratory viral infections, changes in the bone system. Conclusions. Evaluation of the possibility of predicting vitamin D deficiency conditions in children in the antenatal period using a complex of medical and statistical analysis methods reduces the risk of: pathological course of pregnancy, childbirth, the frequency of vitamin D deficiency and deficiency in newborns, affecting mass-growth indicators at birth, neurological symptoms, allergic diseases, respiratory infections in infancy, changes in the bone system in young children. Prevention of the development of vitamin D deficiency conditions in the antenatal period makes it possible to optimize the care of the child population.

Background: Multiple myeloma (MM) is a hematological malignancy characterized by the exponential growth of malignant plasma cells. Individuals diagnosed with MM exhibit a deficiency in vitamin D and may suffer fatigue, a loss of muscular strength, persistent musculoskeletal aches, and pain. The objective of this systematic review and meta-analysis is to determine the prevalence of vitamin D insufficiency and deficiency in individuals diagnosed with MM. Methods: We searched five electronic databases using relevant keywords. The quality of the included studies was evaluated using the critical appraisal tool developed by the Joanna Briggs Institute. We employed a random-effects model and presented the findings in the form of percentages accompanied by 95% confidence intervals (CI). This protocol has been officially registered in PROSPERO under the registration number CRD42021248710. Results: The meta-analysis comprised a total of eighteen studies and found that, among patients with MM, the occurrence of serum vitamin D deficiency and insufficiency was 39.4% (95% CI: 25.8 to 52.9, n = 3746) and 34.1% (95% CI: 20.9 to 47.2, n = 3559), respectively. The findings indicate that a greater proportion of newly diagnosed patients exhibited vitamin D deficiency and insufficiency, with rates of 43.0% and 41.6%, respectively, compared to those receiving treatment (rates of 41.6% and 32.3%, respectively). The findings of the sensitivity analyses were consistent, and most of the studies (72.2%) were deemed to be of high quality. The results of Egger's test indicated the absence of publication bias. Conclusions: Patients diagnosed with MM have been found to exhibit significantly elevated levels of both vitamin D deficiency and insufficiency. Therefore, it is recommended to consider vitamin D testing as an additional parameter in the current criteria for the clinical evaluation of MM. [ABSTRACT FROM AUTHOR]

Despite being close to equator and receiving sufficient sun rays, evidences revealed that Indians have severe deficiency of vitamin D (vit D) ranging from 41 to 100% in different geographical locations. Therefore, in this study levels of 25(OH)D (physiologically measurable form) along with other bone metabolism associated biochemical markers were determined in serum sample of 300 apparently healthy study subjects (rural) from Doiwala block of Dehradun district in the state of Uttarakhand. Demographic data was also obtained based on a structured questionnaire to establish an association between 25(OH)D levels and various dietary and socio-cultural factors. Results demonstrated that of all study subjects, 197 (65%) had 25(OH)D levels below < 12 ng/mL (deficient) and 65 (21%) had 25(OH)D levels between 12 and 20 ng/mL (insufficient) with all other markers falling within respectively established reference ranges. Further, in univariate analysis, gender, occupation (indoor and outdoor), education were independently associated with vitamin D status. Additionally, parathyroid hormone associated significantly with gender and occupation, while calcium associated significantly with gender, occupation and education. Lastly, regression analysis revealed that gender and occupation independently associated with vitamin D status of subjects. In conclusion, apparently healthy subjects showed considerable vitamin D deficiency thereby generating an urgent need for formulating and implementing better government policies for enrichment of vitamin D levels among rural adults of Uttarakhand in future.

Introduction/Objective. Vitamin D not only plays a role in calcium and phosphorus metabolism, but also has antiproliferative, prodifferentiation, anti-inflammatory and immunomodulatory effects. The aim of this study was to investigate the association between vitamin D deficiency in individuals with autoimmune Hashimoto’s thyroiditis. Methods. A total of 156 patients were enrolled and divided into two groups. First group included 108 patients with 25 (OH) D insufficiency, and second included 48 individuals with normal 25 (OH) D levels. All participants underwent a detailed clinical examination, laboratory tests for thyroid function [T3, fT4, TSH, thyroid antibodies (TPO-Ab, and TG-Ab)], as well as ultrasound scanning (thyroid volume and Doppler characteristics). Results. The patients with vitamin D insufficiency (n = 108 (69.2%)) were predominantly female and had a higher body mass index than the patients with normal vitamin D levels. The group with vitamin D insufficiency had statistically significantly higher TSH levels. The prevalence of positive thyroid antibodies was higher in the vitamin D insufficiency group, while thyroid volume, superior thyroid artery, and inferior thyroid arteries resistance index, as well as the prevalence of positive circular dichroism signals, were significantly higher in the vitamin D insufficiency group. Out of the 156 subjects, 44 were diagnosed with thyroiditis (28.2%). The mean serum level of 25 (OH) D was statistically notably lower in patients with thyroiditis (20.23 ± 8.10 ng/mL) than in the group without thyroiditis (25.44 ± 8.38 ng/mL), p < 0.001. Conclusion. There was an association between vitamin D insufficiency and hypothyroidism in subjects with Hashimoto’s thyroiditis.

Abstract Background Fortification of foodstuffs with iodine, mainly through iodization of salt, which commenced in several African countries after 1995 is the main method for mitigating iodine deficiency in Africa. We assessed the degree of iodine nutrition in pregnancy across Africa before and after the implementation of national iodine fortification programs (CRD42018099434). Methods Electronic databases and gray literature were searched for baseline data before implementation of population-based iodine supplementation and for follow-up data up to September 2020. R-metamedian and metamean packages were used to pool country-specific median urinary iodine concentration (UIC) estimates and derived mean UIC from studies with similar features. Results Of 54 African countries, 23 had data on iodine nutrition in pregnancy mostly from subnational samples. Data before 1995 showed that severe iodine deficiency was prevalent in pregnancy with a pooled pregnancy median UIC of 28.6 μg/L (95% CI 7.6–49.5). By 2005, five studies revealed a trend towards improvement in iodine nutrition state in pregnancy with a pooled pregnancy median UIC of 174.1 μg/L (95% CI 90.4–257.7). Between 2005 and 2020 increased numbers of national and subnational studies revealed that few African countries had sufficient, while most had mildly inadequate, and some severely inadequate iodine nutrition in pregnancy. The pooled pregnancy median UIC was 145 μg/L (95% CI 126–172). Conclusion Improvement in iodine nutrition status in pregnancy following the introduction of fortification of foodstuffs with iodine in Africa is sub-optimal, exposing a large proportion of pregnant women to the risk of iodine deficiency and associated disorders.

The variation in vitamin D status is still unclear. We aim to describe the vitamin D status among healthy infants and children in Shanghai (31° N latitude), one of the largest cities in China. We conducted a hospital‐based, 2‐year retrospective observational study and recruited children for health examination at the Tongren Hospital affiliated with Shanghai Jiao Tong University School of Medicine from January 2019 to December 2020. Serum 25‐hydroxyvitamin D (25(OH)D) levels were measured using an enzyme‐linked immunosorbent assay. A total of 6164 children aged 0–11 years were included. Of these, 94.4% of the serum 25(OH)D measurements at first assessment were within the range of 12–50 ng/mL. The median 25(OH)D level was 31.3 (IQR 25.6, 38.1) ng/mL, the percentages of 25(OH)D < 20 ng/mL and 25(OH)D < 30 ng/mL were 10.0% and 43.8%, respectively. Low vitamin D status (deficiency and insufficiency) differed significantly by age group (infants, toddlers, preschoolers, and schoolers) and seasonality (all p <.001), but not by gender. For the sub‐group (n = 855) of children with repeated assessments, their low 25(OH)D levels increased significantly whether after about a 7‐month (n = 351) or 12‐month (n = 504) interval, and the increments of median 25(OH)D levels were 8.1 ng/mL and 2.1 ng/mL respectively (p <.001). This study documents the vitamin D status in Shanghai, showing that low vitamin D status is common in infants and children and suggesting that the assessment of 25(OH)D level is necessary for individuals who are at risk for deficiency or excess.

COVID-19-pandemic-related home confinement aids in limiting the spread of the virus but restricts exposure to sunlight, thereby possibly affecting 25(OH)D concentrations. This study aimed to investigate the effect of lockdown measures on 25(OH)D levels in outpatients visiting the healthcare centre over a period of two years. In this retrospective chart review, outpatients who visited a university healthcare centre for a health check-up over a period of two years were included. The patients' 25(OH)D serum levels and status were compared before, during, and after the lockdown periods. A total of 7234 patients were included in this study, with a mean age of 34.66 ± 16.78. The overall prevalence of 25(OH)D insufficiency, deficiency and sufficiency was 33.8%, 30.7% and 35.4%, respectively. The proportion of individuals with 25-(OH) D deficiency prior to lockdown was 29% and this proportion increased in the lockdown and post-lockdown periods to 31.1% and 32%, respectively. Although gender was less likely to have an impact on the 25 (OH) D level during the lockdown period (p = 0.630), we found an association between gender and 25 (OH) D status in the pre-lockdown and post-lockdown periods (p < 0.001 and p < 0.001, respectively). Another association between nationality and 25 (OH)D levels was found before, during and after the lockdown periods (p < 0.001). In addition, the youngest population, aged between 1 and 14, was strongly affected by the home confinement. Age had a positive and significant (p < 0.05) effect on 25 (OH) D status regardless of the different periods. Moreover, in the pre-lockdown period, male outpatients had 1.56 chance of having a sufficient level of 25 (OH)D. However, during the lockdown period, this chance decreased to 0.85 and then increased to 0.99 after the lockdown period. We found no statistically significant difference in the mean serum concentrations or in the prevalence of vitamin D insufficiency when we compared values from before, during and immediately after the COVID-19 lockdown period. However, there was a generally increased prevalence of vitamin D insufficiency in our study population. Another association between gender, nationality and age groups with 25(OH) D was found. Regular exposure to UVR is recommended for maintaining adequate vitamin D levels and to prevent vitamin D deficiency. Further research is needed to determine the best indications for vitamin D supplementation if confinement periods are extended and to consider the potential health consequences of prolonged confinement periods not only on vitamin D status but also on overall public health. The findings of this study may be considered by stakeholders for a targeted supplementation approach for risk groups. [ABSTRACT FROM AUTHOR]

Abstract Purpose: To evaluate the therapeutic response of retinal vein occlusion (RVO) to intravitreal bevacizumab (IVB) with and without concomitant vitamin D supplementation. Method: Seventy eyes of 68 patients with macular edema associated with branch retinal vein occlusion (BRVO) and central retinal vein occlusion (CRVO) received three monthly IVB injections. Patients with serum 25-hydroxyvitamin D (25(OH) D) higher than 30 ng/ml were considered as the sufficient group. Cases with serum 25(OH) D levels below 30 ng/ml were randomized into the treatment and control groups. The control group received 50,000 IU of oral vitamin D, weekly for two months. One month after the last IVB injection, best-corrected visual acuity (BCVA) and central macular thickness (CMT) were measured and compared with the preinjection values. Results: While 43 eyes (61.4%) of 42 patients had BRVO, 27 eyes (38.6%) of 26 patients had CRVO. In BRVO patients, changes of CMT and BCVA were not significantly different between the sufficient, control, and treatment groups (P = 0.58 and 0.64, respectively). In the CRVO group, CMT reduction in the control group was significantly less than the sufficient and treatment groups (P = 0.048). In addition, improvement of BCVA in the control group was significantly less (P = 0.036) than the sufficient and treatment groups. Conclusion: Oral vitamin D supplement therapy may improve anatomical and functional outcomes in patients with CRVO and vitamin D deficiency.

The paper studies the impact of regional climate changes that occurred in the past and are expected to occur in the near future on the components of the annual fresh water balance of quasi-closed lagoons in the North-Western Black Sea coast. Currently these lagoons have no permanent connection with the sea. However, there are some episodic connections via artificially created channels, ducts and other waterworks. The value of insufficiency of the studied lagoons' annual fresh water balance is used as an indicator of their ecosystems' sensitivity to climate change. Action plans must be created and implemented for the lagoons that are the most sensitive to changes in regional climatic conditions in order to achieve and maintain their "good" environmental quality status. The climate-induced changes of meteorological parameters in the North-Western Black Sea coast that determine the components of the lagoons' water balance are estimated for two periods: the current one from 2000 to 2018 (based on the observations made at coastal meteorological stations) and the near-future one of 2021-2050 which is compared to the 1961-1990 period (based on the data of the Climate Cadastre of Ukraine). The expected climatic conditions in the near future (2021-2050) were determined by the RCM simulations of the Euro-CORDEX project for the RCP4.5 climate change scenario. The research evaluates the components of the lagoons' fresh water balance (precipitation reaching the lagoons' water surface, fresh water inflow from the catchments, evaporation from the lagoons' water surface) and identifies the residuals (shortages) of annual balance. It uses the "climate-runoff" hydrological model for the above climatic periods to determine the fresh water inflow into the lagoons through the watercourses of their catchment areas. The annual evaporation layer from the lagoons' water surface was evaluated using the long-term average monthly values of temperature and relative humidity for each of the periods. It was established that the climatic changes that occurred earlier and those expected in the current century caused and will cause the increasing insufficiency of the annual fresh water balance of quasi-closed lagoons in the North-Western Black Sea coast. This can threaten salinization, shallowing or even disappearance of some lagoons. Thus new strategies for water and environmental management of such lagoons must be developed. In terms of vulnerability to climate changes leading to significant annual insufficiency of fresh water balance (if there are no other water sources, e.g. water from the sea), lagoons are ranked in the following order: Kuialnytskyi Lagoon, Dofinivskyi Lagoon, Budatskyi Lagoon (if there is no water inflow from the Dnistrovskyi Lagoon), the Tuzla group of lagoons, Sasyk Lagoon, Tyligulskyi Lagoon, Hadzhybeisky Lagoon (if there is no anthropogenic runoff).

Background: Periprosthetic femur fracture following total knee arthroplasty (TKA) is a devastating complication. Although trauma-related periprosthetic femur fractures have been well studied, early atraumatic insufficiency periprosthetic fractures (IPFs) are gaining attention. We present the largest IPF series to date to better understand and prevent this complication. Methods: A retrospective study of all patients who underwent a revision surgery for periprosthetic fracture within 6 months of primary TKA between 2007 and 2020 was performed. Patient demographics, preoperative radiographs, implant details, and fracture radiographs were reviewed. Alignment measurements and fracture characteristics were assessed. Results: Sixteen patients met criteria (rate 0.05%), and 11 had posterior-stabilized TKAs. The mean age was 79 years, mean body mass index was 31 kg/m2, and 94% (15/16) were female. Seven (47%) patients had a confirmed history of osteoporosis. IPF occurred on average 4 weeks (range, 4 days-13 weeks) after the index TKA. Overall, 12 of 16 (73%) had preoperative valgus deformities, and 11 patients (10 valgus, 1 varus) had preoperative deformities >10 degrees. A characteristic radiographic appearance of femoral condylar impaction and collapse was noted in 12 of 16 cases (75%); 11 of these 12 fractures (92%) involved the unloaded compartment based on preoperative varus/valgus deformity. Conclusions: Patients who developed IPFs were most commonly elderly, obese women with osteoporosis and severe preoperative valgus deformities. The apparent mechanism of failure was overloading of previously unloaded osteopenic femoral condyle. In high-risk patients, the use of a cruciate-retaining femoral component or a femoral stem for a posterior-stabilized femur may be considered to help avoid this catastrophic complication.

Vitamin D (VitD) is essential for health and preventing diseases. This study aimed to investigate the possible association between VitD status and health status in 306 Libyan male and female young adults (18–25 Y) and adults (26–65 Y). There were 89.54% of subjects that had VitD levels below normal (<30 ng/mL), of which 45.42% were VitD deficient (<10 ng/mL) and 44.12% were VitD insufficient (10–29.9 ng/mL). VitD deficiency was associated with higher fasting blood sugar (FBS), low-density lipoprotein (LDL), and triacylglycerol (TAG) levels. Young adults had lower VitD levels than adults, which was associated with some health conditions. VitD insufficiency was associated with higher body mass index (BMI) values in adults, especially females, with higher FBS levels in adult males and higher hemoglobin A1c (HbA1c) levels in adult females. VitD deficiency in young adults was associated with higher TAG levels (more likely in adults) and lower high-density lipoprotein (HDL) values. Furthermore, VitD deficient adult females appeared to have a higher risk of sleeping problems, psychological disorders, headache, and osteoporosis, whereas their male counterparts appeared to be at a higher risk of developing obesity and diabetes mellitus (DM). Findings showed a serious prevalence of VitD inadequacy in the Libyan population, which appears to negatively affect health status and be associated with some disease conditions.

Lumbar disc degeneration (LDD) is one of the fundamental causes of low back pain. The aims of this study were to determine serum 25-hydroxyvitamin D (25(OH)D) levels and physical performance and to investigate the relationship between serum vitamin D levels, muscle strength and physical activity in elderly patients with LDD. The participants were 200 LDD patients, including 155 females and 45 males aged 60 years and over. Data on body mass index and body composition were collected. Serum 25(OH)D and parathyroid hormone levels were measured. Serum 25(OH)D was classified into the insufficiency group: <30 ng/mL and the sufficiency group: ≥30 ng/mL. Muscle strength was assessed by grip strength, and physical performance (short physical performance battery) was evaluated by the balance test, chair stand test, gait speed, and Timed Up and Go (TUG) test. Serum 25(OH)D levels in LDD patients with vitamin D insufficiency were significantly lower than in those with vitamin D sufficiency (p < 0.0001). LDD patients with vitamin D insufficiency had a prolonged time in physical performance on gait speed (p = 0.008), chair stand test (p = 0.013), and TUG test (p = 0.014) compared to those with vitamin D sufficiency. Additionally, we found that serum 25(OH)D levels were significantly correlated with gait speed (r = −0.153, p = 0.03) and TUG test (r = −0.168, p = 0.017) in LDD patients. No significant associations with serum 25(OH)D status were observed for grip strength and balance tests among patients. These findings demonstrate that higher serum 25(OH)D levels are associated with better physical performance in LDD patients. [ABSTRACT FROM AUTHOR]

Although there are innumerable studies on vitamin D deficiency in India, there is limited data in Mizoram. Keeping this in view the aim of our study is to find out the deficiency of Vitamin D in our region, Mizoram (NE India). Our study population included patients attending Genesis Laboratory, Aizawl, Mizoram (November 2021 - November 2022) for various ailments who were advised serum Vitamin D level estimation. The study population was grouped according to gender and age in decades. Blood was collected in plain vials and serum obtained was used for vitamin D estimation. Out of 480 patients, 180 were male and 300 were female. Age of the study population ranged from 11 - 79 years. 17% of the total study population had normal values, 62.7% was vitamin D Deficient and 20.3 % showed Vitamin D insufficiency. The prevalence of Vitamin D Deficiency was high in all age groups, there were a higher percentage of females in the vitamin D insufficient and deficient groups. Maximum numbers of patients with vitamin D deficiency were in the age group of 60-69 years with a female predominance. Prevalence of Vitamin D deficiency is very high in our region that is in Mizoram, as is reflected from our study. This pattern is seen in other parts of our country too. Also, the deficiency is high in the age groups N - N years and females outnumbered male. [ABSTRACT FROM AUTHOR]

Ichthyosis vulgaris (IV) is a non-syndromic form of congenital ichthyoses and mainly affects the skin, moreover in severe case followed by joints involvement and vitamin D imbalance as chronic complication due to skin barrier impairment. A 16-years-old female presented with scaly skin all over her body. Changes on her hands appeared when she was 8-years-old and several years later gradually she could not use her hands. Dermatological examination obtained thick scales, xerotic skin, and palmo-plantar hyperkeratosis. The dermoscopic finding was a fine white scale with a criss-cross pattern. Her skin biopsy showed hyperkeratosis and thinning of granular layer, meanwhile laboratory results indicated vitamin D insufficiency. Hand x-ray revealed flexion contractures. She received oral vitamin D3 400 IU once daily, calcitriol 0.5 mcg twice daily, and topical emolients. Surgical contracture release was conducted to repair the joints deformity. Manifestation of IV is limited to the skin and rarely accompanied by other systemic disorders. Joint anomaly might be seen in some syndromes accompined with ichthyoses, however IV does not lead to joint contractures. Skin thickness and impaired barrier could lead to reduced ultraviolet B penetration, so that it disturbed and diminished vitamin D synthesis. Those conditions are more likely to cause muscle weakness and atrophy which finally lead to joints contractures. [ABSTRACT FROM AUTHOR]

Abstract Background Endoscopic vacuum therapy (EVT) has become a standard treatment method for esophageal perforations in adults. However, experience with EVT in infants is scarce. In this retrospective case series, we report on four very young infants who were successfully treated with EVT for esophageal perforations of different etiology. Methods Four infants were diagnosed with esophageal perforations on day 7, 32, 35 and 159 of life, respectively. The youngest one was prematurely born in the 31st week of pregnancy weighing 980 g only. Three infants had perforations due to foreign body insertion (nasogastric tube or pulling through of percutaneous endoscopic gastrostomy (PEG) tube through the esophagus). One child had an anastomotic dehiscence after Foker’s surgery for atresia. In three children EVT was applied as first-line therapy for perforation, in one child EVT was a rescue therapy due to persisting leakage after surgical closure involving thoracotomy. Depending on the esophageal diameter, either an open-pore drainage film or polyurethane sponge was attached to a single-lumen 8 Fr suction catheter, endoscopically (or fluoroscopically by wire-guidance) placed into the esophagus (intraluminal EVT) and supplied with continuous negative pressure (ranging between 75 and 150 mmHg). The EVT system was exchanged twice per week. Results Complete closure of the perforation/leakage could be achieved in all four infants (100%) after 22 days of continuous EVT (median value; range 7–39) and 4.5 EVT exchanges (median value; range 1–12). No serious adverse events occurred. Conclusions EVT is an effective and safe addition to our therapeutic armamentarium in the management of esophageal perforations irrespective of its etiology. Here we prove the feasibility of EVT even in very young infants. The use of an extra thin vacuum open-pore drainage film is helpful to cope with the small esophageal diameter. EVT settings and exchange rates similar to those known from adult treatment were used.

Abstract Background Vitamin D is vital for the growth and development of children. While deficiency and/or insufficiency of vitamin D among South Asian children are frequently reported in the literature, the lack of a meta-analysis has left its true extent poorly characterized. In this study, we aimed to conduct a systematic review and perform meta-analyses of the prevalence of hypovitaminosis D among the children of the South Asian countries. Methods Two major electronic search engines (PubMed and Scopus) and one database (Google scholar) were used; original studies, conducted among South Asian children and adolescents and published between 1 January 2001 and 31 December 2019. A random-effect meta-analysis was also performed to calculate the pooled prevalence of hypovitaminosis D followed by subgroup analyses for countries and age groups. Results After applying inclusion and exclusion criteria, a total of 41 studies with a total population size of 18,233 were finally selected. The overall prevalence of hypovitaminosis D was 61% [95% CI: 46% to 71%] with highly significant heterogeneity (I 2 = 99.72%; p

Vitamin D (VitD) insufficiency is a worldwide health problem and affects billions of people. Spinal cord injury (SCI) patients seem more susceptible to developing suboptimal levels of VitD. However, the literature regarding its impact on the prognosis of SCI is limited. Thus, in this review, we systematically investigated the published studies via a combination of keywords associated with SCI and VitD in four medical databases (Medline, Embase, Scopus, and Web of Science). All included studies were analyzed, and selected clinical data on the prevalence of VitD insufficiency (serum 25-hydroxyvitamin D < 30 ng/ml) and deficiency (serum 25-hydroxyvitamin D < 20 ng/ml) were collected for further meta-analysis via random effects. Through literature review, a total of 35 studies were eligible and included. The meta-analysis of VitD status (13 studies, 1,962 patients) indicated high prevalence of insufficiency (81.6% [75.7, 87.5]) and deficiency (52.5% [38.1, 66.9]) after SCI. Besides, low levels of VitD were reported to be associated with a higher risk of skeletal diseases, venous thromboembolism, psychoneurological syndromes, and chest illness after injury. Existing literature suggested that supplemental therapy might act as an adjuvant treatment to facilitate post-injury rehabilitation. Non-human experimental studies highlighted the neuroprotective effect of VitD, which was associated with enhancing axonal and neuronal survival, suppressing neuroinflammation, and modulating autophagy. Therefore, the current evidence suggests that the prevalence of VitD insufficiency is high in the SCI population, and low-level VitD may impair functional restoration after SCI. VitD supplemental treatment may have potential benefits to accelerate rehabilitation in mechanistically related processes after SCI. However, due to the limitation of the available evidence, more well-designed randomized controlled trials and mechanism experimental research are still needed to validate its therapeutic effect, elucidate its neuroprotective mechanism, and develop novel treatments.

Objective: Vitamin D (VitD) has been shown to influence several cellular processes in the brain. The extent to which VitD plays a role in the pathomechanism of neuronal loss and dysfunction in basal ganglia diseases (BGDs) is still debated. There is yet to be a comprehensive study that provides an overview of all of the most relevant BGDs. Methods: PubMed, and Google Scholar were systematically searched for observational studies that investigated the association between serum VitD levels and BGDs up to March 2022. Results: We extracted 60 studies, but with a great variety of design and quality. VitD deficiency appears to be common in most BGDs, but only in Parkinson's disease (PD) has a causal association been fully examined. There is some evidence that low VitD serum levels influence symptom severity, most notably in restless legs syndrome (RLS), PD, and tic disorders. The effects of vitamin D supplementation were studied in three BGDs, with results mostly favorable for RLS, ambiguous for tics, and mostly unfavorable for PD. Conclusions: There are still various elements of BGDs with insufficient, ambiguous, or altogether absent evidence, and further high-quality research is required. However, there appears to be sufficient scientific justification already to recommend that practitioners treating BGDs check serum VitD levels and supplement as appropriate. [ABSTRACT FROM AUTHOR]

Introduction: Despite similar fracture rates, the incidence of intraoperative and post-operative fractures between standard (ST) length and short (SH) femoral stems remains unclear. Therefore, this study compared the incidence of intraoperative and early postoperative fractures between three ST and a single tapered-wedge SH femoral stem. Materials and methods: Data were retrospectively collected on 1113 patients (1306 hips) having undergone total hip arthroplasty, via the anterior approach on a fracture table, between 2014 and 2019. One surgeon completed all ST procedures (314 hips), using one of three implants without discretion. One surgeon completed all SH procedures (992 hips), using one implant design. Differences between ST and SH groups were evaluated by independent t tests (continuous variables) and Chi-square tests (categorical variables). Results: Patients in the SH group were significantly older (p < 0.001) and had a lower body mass index (p = 0.001) compared to the ST group. The total number of fractures was 12 (3.8%) and 14 (1.4%) in the ST and SH groups, respectively. The 12 ST fractures occurred intraoperatively, compared to two (0.2%) in the SH group. The remaining seven (0.7%) SH fractures occurred post-operatively. There was no difference in fracture rate between the three ST designs (p = 0.882). Interestingly, five (0.5%) insufficiency fractures were diagnosed in the SH group. Conclusion: The risk of intraoperative and post-operative fractures following anterior total hip arthroplasty may be biased toward ST and SH implants, respectively. These results, along with the presence of five insufficient fractures, identify potential fracture risks and mechanisms for specific implant designs. [ABSTRACT FROM AUTHOR]

Sacral insufficiency fractures after lumbosacral fusion continue to establish themselves as a rare complication after surgery. The diagnosis can often be missed due to inconclusive imaging and non-specific symptoms. In the literature, the treatment of sacral insufficiency fractures varies from non-operative and conservative management to surgical intervention with lumbopelvic fixation. We performed a systematic review searching the PubMed database using sacral insufficiency fracture treatment after lumbosacral fusion and sacral insufficiency fracture after posterior spinal instrumentation as keywords. This search strategy identified 32 publications from the PubMed database for literature review. After evaluating the inclusion and exclusion criteria, a total of 17 articles were included in the review. 65% of sacral insufficiency fractures were managed surgically with 35% of patients proceeding with non-operative, conservative management only. Revision surgery always involved sacropelvic fixation which typically led to immediate resolution or reduction of symptoms, with the exception of 2 cases that did not receive adequate reduction of symptoms. Five cases reported failed non-operative management that subsequently responded to revision surgery. Outcomes after non-operative management usually leads to symptom resolution; however has a slower symptom relief time as well as a higher chance of failed treatment. Operative outcomes, generally with a variation of sacropelvic fixation lead to immediate symptom resolution and very rarely failed treatment. Clinicians must always maintain a high index of suspicion of new onset lower back or sacral pain after lumbosacral surgery and order a CT scan to rule out a potential insufficiency fracture. The objective of this study was to review the literature to examine treatment options for sacral insufficiency fractures after lumbosacral fusion in order to improve clinical practice and management. This systematic review of the literature regarding treatment of sacral insufficiency fractures will assist clinicians in making the accurate diagnosis and devise a strategic treatment plan for patients with sacral insufficiency fractures after spinal instrumentation.

Non-invasive screening tools to identify children at high risk of vitamin D (VitD) deficiency are proactive measures in preventive care. Recently, a validated questionnaire (Evaluation dEficieNCy Questionnaire, EVIDENCe-Q) for identifying newly diagnosed VitD-insufficient adults has been developed. We tested the EVIDENCe-Q modified for children with obesity and evaluated the correlation between VitD and questionnaire scores to adapt this tool to the pediatric population. We enrolled 120 children with obesity (BMI ≥ 2). Clinical evaluation and VitD levels were considered. The modified EVIDENCe-Q included information regarding factors affecting control of VitD, with scores ranging between 0 (best) and 36 (worst). VitD and adiposity indices were inversely correlated. The threshold values for identifying severe deficiency (<10 mg/dL), deficiency (<20 mg/dL) and insufficiency (<30 mg/dL) were scores of 21, 19 and 23, respectively. According to those thresholds, the prevalence of severe deficiency, deficiency and insufficiency was 47.5%, 69.2% and 23.3%, respectively; the best accuracy was obtained with a questionnaire score cut-off of 19 for the VitD deficiency level. A novel simple screening tool such as the modified EVIDENCe-Q would be useful in clinical practice to identify potential cases of hypovitaminosis D and select at-risk patients. Considering the limited accuracy and specificity of our results, for the pediatric population a dedicated tool should be created. Phases of childhood and the role of adipose tissue could be considered in the definition of a questionnaire intended for pediatric patients with obesity. [ABSTRACT FROM AUTHOR]
