Workplace problems that are likely to increase the risk to our health are referred to as occupational hazards. These problems can be classified as either biological or non‑biological. A wide range of these risks, including physical, chemical, and psychological ones, provide challenges for healthcare practitioners. Such risks therefore negatively affect employees, their families, friends, and the country. The purpose of the study is to assess the level of adherence to preventive practices towards occupational hazards in the hospitals of Thi‑Qar Governorate and its relationship to the demographic and occupational information of the healthcare workers. A descriptive cross‑sectional study was carried out in hospitals Thi‑Qar Governorate, During the period from September 5th, 2022 ending on February 10th,2023, 355 of healthcare workers individuals participated in the study, and the data was collected using self‑reported questionnaires and information about practices was collected through a systematic questionnaire developed by the researcher. Regarding the preventive practice of the staff, the results observed that all responses regarding the present results reveal the highest percentage 41.7% of HCWs have a poor practices score, while the lowest percentage 20.8% of them have a moderate practices score. The mean ± SD of the overall practices score was (53.81±17.807) which rested within a moderate level (48‑46 score). The results of this study indicate that there is a significant association between the overall practices score and socio‑demographic variables (P‑value 0.05). This explained that the participants who age ≤25 years, Education level (Ph.D.), and have no chronic diseases, had higher good practices than other categories. Also, the results of this study indicate that there is a significant association between the overall practices score and occupation characteristics (P‑value 0.05), This explained that the years of work (≥15 years), and,hours of work (≤5 h), had higher good practices than other categories. Most of the employees of the hospitals selected for the sample in Thi‑Qar Governorate have ‘Moderate’ commitments to safety measures with regard to occupational hazards in their surrounding workplaces, The study showed that years of experience, time of work and educational level have a significant impact on practices towards occupational hazards in hospitals.

Background: Erectile dysfunction (ED) and sex hormone profile disturbances are common in ESRD patients., Objective: To assess the effect of kidney transplant (KT) and Hemodialysis/peritoneal dialysis (HD/PD) on the serum sex hormone profile and sexual functions in ESRD patients with ED., Patients and Methods: A single-center, nonconcurrent cohort study included a hundred ESRD patients with ED, on regular HD/PD (group A, n = 50) and after KT (group B, n = 50) at Armed Forces Hospitals Southern Region, KSA., Results: the mean age of patients was 47.3 ± 7.01 and 56.8 ± 9.6 years in groups A and B, respectively. The cohorts were comparable regarding patient demographics, apart from a higher incidence of comorbidities in group B. After KT the mean testosterone level was higher in Group B (13.64 ± 3.21 nmol/L vs 10.26 ± 3.26 nmol/L, p < 0.001). Similarly, LH and prolactin levels were lower in group B than in group A (p < 0.05). As regards sexual function, ED was reported in 92% of patients in group A compared to 42% in group B (p < 0.001). In groups A and B, mild ED was found in 48% and 14% of patients, while moderate ED was found in 16% and 8%, respectively. The mean total IIEF-15 score was 36.42 ± 9.33 and 43.87 ± 9.146 in groups A and B, respectively (p = 0.0001). Sexual desire and orgasm were significantly better in Group B., Conclusions: Our study showed that kidney transplantation could improve erectile function and restore normal sex hormone levels in ESRD male patients with ED, with better outcomes compared to HD/PD.

Objective: To assess the efficacy and safety of Sildenafil citrate in the treatment of ED in (HD) compared to post-RT patients., Patients and Methods: A concurrent cohort prospective study to evaluate the efficacy of Sildenafil in the treatment of ED in 24 HD patients (Group A) and 13 patients with persistent ED one-year post-RT (Group B). The initial dose of Sildenafil was 25 mg, increased to 50 mg if there is an adequate response. An Arabic-translated International Index of Erectile Function (IIEF) questionnaire was completed one week before and after Sildenafil treatment. An IIEF erectile function score of 26 or an improvement of at least 10 points for the total IIEF score was considered a favorable response to Sildenafil., Results: Group A included 22 patients with a mean age of 47.32 ± 7.013 years, whereas Group B included 13 patients with a mean age of 56.87 ± 9.612 years. The overall efficacy rate of Sildenafil was 40.9% and 76.9% in groups A and B, respectively. The post-treatment IIEF5-15 score increased from 11.1 ± 5.99 to 12.5 ± 6.41 (p = .458) and from 11.82 ± 7.534 to 21.91 ± 5.700 (p = .002) in groups A and B, respectively. In both groups, the duration of HD had no impact on ED improvement except in the post-RT non-responder subgroup. Hypertension, gastrointestinal symptoms, and flushing were both groups' most common side effects., Conclusion: RT could enhance the response to sildenafil in treating patients with ED. The outcome is better in younger post-RT patients with moderate and severe erectile dysfunction and shorter dialysis duration., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

Microgravity-induced bone loss increases urinary calcium excretion which increases kidney stone formation risk. Not all individuals show the same degree of increase in urinary calcium and some pre-flight characteristics may help identify individuals who may benefit from in-flight monitoring. In weightlessness the bone is unloaded, and the effect of this unloading may be greater for those who weigh more. We studied whether pre-flight body weight was associated with increased in-flight urinary calcium excretion using data from Skylab and the International Space Station (ISS). The study was reviewed and approved by the National Aeronautics and Space Administration (NASA) electronic Institutional Review Board (eIRB) and data were sourced from the Longitudinal Study of Astronaut Health (LSAH) database. The combined Skylab and ISS data included 45 participants (9 Skylab, 36 ISS). Both weight and day in flight were positively related to urinary calcium excretion. There was also an interaction between weight and day in flight with higher weight associated with higher calcium excretion earlier in the mission. This study shows that pre-flight weight is also a factor and could be included in the risk assessments for bone loss and kidney stone formation in space., (© 2023. The Author(s).)

Purpose of Review: Weightlessness increases both bone loss and kidney stone formation risk. The large interior volume of the International Space Station (ISS) has allowed for a mix of exercise devices to help maintain the skeleton. But space exploration is changing. Long stays on the ISS will be replaced by journeys in smaller spacecraft both to and around the Moon. Small private space stations are under development. This will limit the ability to do exercise countermeasures, which can increase both bone loss and kidney stone risk. This review examines this risk and how it can be minimized in this new era of spaceflight., Recent Findings: Simple, low-mass, low-power ways to track bone loss and kidney stone risk in space are being researched. Tracking urinary calcium concentration in the first morning void and targeting additional countermeasures (e.g. bisphosphonates) to those who run consistently high levels is one promising approach., Summary: New exploration spacecraft would not have the room and capability to replicate the current 2 h, daily exercise countermeasure programme on the ISS. A monitoring approach, perhaps using urinary calcium as a marker, is needed to find those at greatest risk. This would allow countermeasures to be targeted individually and used efficiently., (Copyright © 2022 Wolters Kluwer Health, Inc. All rights reserved.)

Background: Obstetrical brachial plexus palsy (OBPP) is a relatively common stretch injury of the brachial plexus sustained during delivery. Tendon transfers are commonly performed to improve shoulder function among patients with OBPP. Although several techniques for the surgical management of OBPP exist, it is unclear whether tendon transfers to the rotator cuff vs. posterior humerus yield different outcomes., Methods: A systematic search in PubMed, Web of Science, the Cumulative Index to Nursing and Allied Health Literature, the Cochrane Library, and Google Scholar up to January 1, 2021, was performed. Relevant publications were classified by surgical technique of tendon transfers to the rotator cuff or posterior humerus. The standard mean difference (SMD) and 95% confidence intervals were calculated to compare preoperative and postoperative aggregate Mallet scores as well as abduction and external rotation scores using the Mallet scale. A p value of <0.01 was considered significant., Results: Data from 26 studies and 951 patients (46.2% male patients) with a mean age of 68.9 ± 29.3 months were included. Eight hundred three patients underwent tendon transfer to the rotator cuff and 148 to the posterior humerus. The average postoperative follow-up period was 45.2 ± 21.7 months. The pooled cohort had an overall improvement in postoperative aggregate Mallet scores (SMD = 5.53, p < 0.001), abduction scores (SMD = 1.79, p < 0.001), and external rotation scores (SMD = 1.99, p < 0.001). Tendon transfer to the rotator cuff had a greater postoperative improvement in abduction (SMD = 1.90, p < 0.001) than transfer to the posterior humerus (SMD = 1.32, p < 0.001) while both techniques yielded similar improvements in external rotation (rotator cuff SMD = 2.01, p < 0.001, posterior humerus SMD = 1.98, p < 0.001)., Conclusion: This is the first systematic review comparing outcomes for tendon transfers to the rotator cuff vs. the posterior humerus for improving shoulder function in patients with OBPP. Overall, tendon transfers are an effective treatment for improving shoulder function. Transfer of the latissimus dorsi and teres major to the rotator cuff compared with transfer to the posterior humerus results in greater improvement in abduction while both techniques have similar results in improving external rotation., Level of Evidence: Level I Systematic review of Level I and Level II studies., Competing Interests: Disclosure: The Disclosure of Potential Conflicts of Interest forms are provided with the online version of the article (http://links.lww.com/JBJSREV/A889)., (Copyright © 2023 by The Journal of Bone and Joint Surgery, Incorporated.)

INTRODUCTION: Microgravity exposure unloads the skeleton. This increases urinary calcium excretion, which reflects both increased bone loss and kidney stone formation risk. We studied the probability that first morning void (FMV) urinary calcium (Uca) measurements would capture the highest Uca concentration in a day. METHODS: For 8 wk, three men and three women collected void-by-void 24-h urine samples weekly. Uca concentration was analyzed using a calcein-based system. Uca concentrations were ranked among all samples from each person. FMV and non-FMV (nFMV) Uca concentrations were compared with a Mann Whitney U -test. The probability that an FMV would capture the highest Uca concentration in a day was assessed. RESULTS: Among 377 voids collected, 46 were FMV and 331 were nFMV. Among all samples, the Uca concentration for FMV was significantly higher than nFMV ( P < 0.0001). Out of the 46 FMVs, 24 were highest in Uca concentration for the corresponding 24-h period, giving a 52.2% probability that any given FMV would capture the highest Uca concentration in a day. The probability of measuring the highest Uca concentration from at least 1 d increased to 77.1%, and 89.1% when two or three FMVs were collected respectively. DISCUSSION: Acquiring 2-3 repeated FMVs provides a high likelihood of capturing the highest Uca from a day. This suggests repeated first morning void Uca concentrations could assess the risk of bone loss and kidney stone formation, which may provide ability for real-time implementation of countermeasure programs to prevent bone and renal complications in prolonged spaceflight.

Aim: To assess incidence and characteristics of post-laparoendoscopic single-site donor nephrectomy (LESS DN) testicular pain., Materials and Methods: A prospective comparative study of all male donors post-left LESS DN (group A) vs. postopen nephrectomies (group B) was performed at our center. Patients' demographics, perioperative data, and postoperative consultation reports were reviewed. Testicular pain, swelling, numbness, urinary symptoms, and sexual dysfunction were evaluated. Patients with a history of scrotal pathology or surgical procedure were excluded. Pain and tenderness were scored on a standard 10-point scale., Results: From September 2017 to December 2020, 85 and 35 male patients of groups A and B met the evaluation criteria. Ipsilateral testicular pain developed in 11 patients (15.3%) and 2 patients (9.5%) in groups A and B, respectively. In most instances, the pain was mild to moderate in severity, started after 6 ± 2.1 and 4 ± 1.1 days postoperatively in groups A and B, respectively. Six patients in group A were evaluated with transscrotal ultrasonography that showed no abnormalities. All patients in both groups responded well to medical treatment., Conclusions: Post-LESS DN ipsilateral testicular pain is usually mild and self-limited. Preoperative patient education and discussion of the possibility of development of testicular pain and its management should be an integral component of laparoscopic donor nephrectomy informed consent., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2022 Hany M.
