ABSTRACT

Although hypothalamo-pituitary-gonadal axis is active during mini-puberty, its relationship with somatic growth and the role on the development of external genitalia has not been fully elucidated. We aimed to evaluate the effects of somatic growth and reproductive hormones on the development of external genitalia during mini-puberty. Anthropometric data, pubertal assesment, serum follicle-stimulating hormone (FSH), luteinizing hormone (LH), dehydroepiandrosterone sulfate (DHEAS), androstenedione (A4), sex-hormone binding globulin (SHBG), estradiol (E2) and inhibin-B, testosterone (T), and anti-Mullerian Hormone (AMH) of healthy infants aged 1-4 months were evaluated. Free sex hormone index was calculated as T/SHBG for boys and E2/SHBG for girls. The mean age of 148 (74 female) infants included in the study was 2.31 ± 0.76 months. Tanner stage 2-3 sex steroid and gonadotropin levels were observed. A statistically significant difference was found between the weight, height, BMI, weight gain and serum FSH, LH, and A4 measurements of girls and boys (p < 0.05). Penile length was associated with weight (r = 0.24, p = 0.03), height (r = 0.25, p = 0.02), and AMH (r = 0.3, p = 0.01), but not with testosterone (p = 0.56 respectively). A negative correlation was found between weight and serum LH (r = – 0.26, p = 0.2) and T/SHBG levels in males (r = – 0.38, p = 0.015 respectively). Weight-SDS was negatively correlated with testosterone in males (r = – 0.25, p = 0.02). Testicular size and breast stage did not correlate with any of the hormonal and anthropometric parameters. Conclusions: External genitalia in males during mini-puberty is related more to somatic growth rather than reproductive hormones. Similar to pubertal developmental stages, both total and free testosterone are negatively associated with higher weight during mini-puberty. What is Known: • Mini-puberty allows early assessment of HPG axis function in infancy. • There is an inverse relationship between the amount of adipose tissue and circulating testosterone levels in males during puberty and adulthood. • The potential effect of somatic growth and reproductive hormones on external genital development during mini-puberty remains unclear. What is New: • During mini-puberty, males’ external genitalia is more related to somatic growth than to reproductive hormones, but this relationship is not observed in girls. • Both total and free testosterone are negatively associated with higher weight during mini-puberty, similar to the pubertal developmental stages.

ABSTRACT

PURPOSE: Prader-Willi syndrome is a serious genetic condition, capable of causing endocrinological imbalance, which has as one of its main treatments the growth hormone therapy. However, this therapy still causes some uncertainty concerning its effects on the respiratory parameters of those patients, especially in cases of obstructive sleep apnea, therefore, presenting a need for the analysis of the relationship between the therapy and the otolaryngologic condition.

METHODS: A systematic review following the PRISMA model was developed, with searches for keywords made in the databases PubMed (MEDLINE), Scopus, and Web of Science and registration in the PROSPERO platform (CRD42023404250).

RESULTS: Three randomized controlled trials were considered eligible for inclusion in the review. None of the studies demonstrated statistically significant modifications in the obstructive sleep apnea parameters of Prader-Willi patients related to the growth hormone administration.

CONCLUSIONS: Growth hormone therapy is safe for Prader-Willi syndrome patients when analyzing their obstructive sleep apnea parameters.

ABSTRACT

INTRODUCTION: While the efficacy of closed suction drains has been extensively studied in hip, knee, and shoulder surgery, it lacks scientific evidence in the foot and ankle domain, especially after total ankle arthroplasty (TAA). Thus, this study aims to compare the incidence of postoperative complications with and without the application of a closed suction drain following TAA.

MATERIALS AND METHODS: A retrospective monocentric chart review of all patients who had undergone TAA with an anterior approach from January 2020 to March 2023 was performed. Data were analyzed to assess the effect of drain usage on postoperative complications.

RESULTS: A total of 110 patients were enrolled, 59 in the drain group and 51 without a drain. The mean age at surgery was 58.4 (range 28-81) years. No statistical differences were found between the two groups in the total complication rate (19.6% in no-drain group versus 20.3% in drain group, p = 0.227).

CONCLUSION: This study showed no effect of applying a closed suction drain after TAA in the incidence of postoperative complications. Since the use of a drain did not negatively affect the outcome, nor did it provide a significant benefit, it can be asserted that there is no evidence to support the routine use of closed suction drains in TAA.

ABSTRACT

OBJECTIVES: The purpose of this study was to determine sex differences in recovery trajectories of assessments for sport-related concussion using Concussion Assessment, Research and Education (CARE) Consortium data.

METHODS: National Collegiate Athletic Association athletes (N = 906; 61% female) from sex-comparable sports completed a pre-season baseline assessment and post-sport-related concussion assessments within 6 h of injury, 24-48 h, when they initiated their return to play progression, when they were cleared for unrestricted return to play, and 6 months post-injury. Assessments included the Standardized Assessment of Concussion, Balance Error Scoring System, Brief Symptom Inventory-18, Immediate Post-concussion Assessment and Cognitive Testing (ImPACT), Sport Concussion Assessment Tool-3 symptom evaluation, Clinical Reaction Time, King-Devick test, Vestibular Ocular Motor Screen, 12-item Short-Form Health Survey, Hospital Anxiety and Depression Scale, and Satisfaction with Life Scale.

RESULTS: Only the Vestibular Ocular Motor Screen Total Symptom Score at the 24-48 h timepoint (p = 0.005) was statistically significantly different between sexes. Specifically, female athletes (mean = 60.2, 95% confidence interval [CI] 51.5-70.4) had higher Vestibular Ocular Motor Screen Total Symptom Scores than male athletes (mean = 36.9, 95% CI 27.6-49.3), but this difference resolved by the time of return-to-play initiation (female athletes, mean = 1.8, 95% CI 1.1-2.9; male athletes, mean = 4.1, 95% CI 1.5-10.9).

CONCLUSIONS: Sport-related concussion recovery trajectories for most assessments were similar for female and male National Collegiate Athletic Association athletes except for Vestibular Ocular Motor Screen symptoms within 48 h of sport-related concussion, which was greater in female athletes. Female athletes had a greater symptom burden across all timepoints, suggesting that cross-sectional observations may indicate sex differences despite similar recovery trajectories.

ABSTRACT

BACKGROUND: Arteriovenous fistula represents the preferred vascular access for patients with kidney failure requiring hemodialysis. Surgeons have traditionally used physical examination to identify the most suitable vessels. This meta-analysis aims to evaluate whether ultrasound mapping should be routinely performed before arteriovenous fistula creation.

METHODS: Medline, Scopus, Web of Science and CENTRAL were systematically searched from inception to November 1, 2022. Randomized controlled trials and cohort studies comparing routine ultrasound mapping to physical examination in terms of arteriovenous fistula patency were included. Meta-analysis was performed by fitting random-effects models. The study protocol has been prospectively registered in PROSPERO (CRD42023402390).

RESULTS: Overall, 18 studies were included, comprising 3655 participants. Routine pre-operative ultrasound mapping was associated with significantly lower rates of primary arteriovenous fistula failure (Risk Ratio-RR: 0.56, 95% confidence intervals-CI: 0.37-0.84, low certainty). A significant outcome was observed by separately pooling randomized controlled trials (RR: 0.37, 95% CI: 0.25-0.54). Routine ultrasound mapping was also associated with significantly higher rates of 1-year primary arteriovenous fistula patency (RR: 1.33, 95% CI: 1.19-1.47, moderate certainty). This effect remained significant in the analysis of randomized controlled trials (RR: 1.26, 95% CI: 1.02-1.56).

CONCLUSIONS: Implementing routine pre-operative ultrasound mapping of vessels is associated with significantly better outcomes in terms of early arteriovenous fistula failure and primary patency rates at 12 months. Further research should confirm the long-term benefits of routine ultrasound examination and evaluate its cost-effectiveness in different populations.

ABSTRACT

BACKGROUND AND OBJECTIVE: Adverse drug events (ADEs) are becoming a significant public health issue. However, reports on ADE-related mortality are limited to national-level evaluations. Therefore, we aimed to reveal overall trends in ADE-related mortality across the 21st century on an international level.

METHODS: This observational study analysed long-term trends in ADE-related mortality rates from 2001 to 2019 using the World Health Organization Mortality Database. The rates were analysed according to sex, age and region. North America, Latin America and the Caribbean, Western Europe, Eastern Europe and Western Pacific regions were assessed. Fifty-four countries were included with four-character International Statistical Classification of Disease and Related Health Problems, Tenth Revision codes in the database, population data in the World Population Prospects 2019 report, mortality data in more than half of the study period, and high-quality or medium-quality death registration data. A locally weighted regression curve was used to show international trends in age-standardised rates.

RESULTS: The global ADE-related mortality rate per 100,000 population increased from 2.05 (95% confidence interval 0.92-3.18) in 2001 to 6.86 (95% confidence interval 5.76-7.95) in 2019. Mortality rates were higher among men than among women, especially in those aged 20-50 years. The population aged ≥ 75 years had higher ADE-related mortality rates than the younger population. North America had the highest mortality rate among the five regions. The global ADE-related mortality rate increased by approximately 3.3-fold from 2001 to 2019.

CONCLUSIONS: The burden of ADEs has increased internationally with rising mortality rates. Establishing pharmacovigilance systems can facilitate efforts to reduce ADE-related mortality rates globally.

ABSTRACT

Baby foods contain these toxic heavy metals which occur naturally or from pollution in the environment. The purpose of this research is to investigate the concentration of heavy metals in the biscuit samples that are commonly used in Iraq as food babies. The concentrations of three metals viz zinc (Zn), lead (Pb), and cadmium (Cd) are measured using atomic absorption spectroscopy (Buck Scientific/USA, 210 VGA). Health risk parameters such as Estimated Daily Intake (EDI), Target Hazard Quotients (THQ), Hazard Index (HI), and Carcinogenic Risk (CR), are determined. The average values of the concentrations of Zn, Pb, and Cd in these samples of biscuits are 0.584 ± 0.099 mg/kg, 0.066 ± 0.008 mg/kg, and 0.205 ± 0.011 mg/kg, respectively, while the average values of HI and CR × 10^-6 for all samples are 0.768 ± 0.040 and 1.94 ± 0.25, respectively. On the basis of comparing these elements, the study finds that the average value of Zn is dominating with the highest concentration, followed by Cd, and Pb. This is relied on the statistical examination that revealed a weak correlation and no significance (p > 0.05) in the amounts of these heavy metals in all samples. The concentrations of Cd, in seven samples, are relatively higher than their permissible limits according to FAO/WHO (0.2 mg/kg). Conversely, the concentrations of Zn and Pb are lower than their permissible limits which was 9.4 mg/kg and 0.3 mg/kg, respectively. The values of health risk parameters for Zn, Pb, and Cd for all samples do not surpass their permissible intake limits according to FAO/WHO, Therefore, it is concluded that the overall estimated healthy risk, due to the heavy metals, is safe since it is within the permissible limits; thus, there are no concerns for a baby who consume biscuit consistently daily.

ABSTRACT

PURPOSE: In breast cancer, neoadjuvant chemotherapy (NAC) can downstage the nodal status, and can even result in a pathological complete response, which is associated with improved prognosis. This study aimed to determine the prognostic effect of nodal status before and after NAC.

METHODS: Women with breast cancer treated with NAC were selected from the Netherlands Cancer Registry if diagnosed between 2005 and 2019, and classified based on nodal status before NAC: node-negative (cN0), or node-positive based on fine needle aspiration cytology or core needle biopsy (cN+). Subgroups were based on nodal status after NAC: absence (ypN0) or presence (ypN+) of nodal disease. Five-year overall survival (OS) was assessed with Kaplan-Meier survival analyses, also per breast cancer molecular subtype. To adjust for potential confounders, multivariable analyses were performed.

RESULTS: A total of 6,580 patients were included in the cN0 group, and 11,878 in the cN+ group. The 5-year OS of the cN0ypN0-subgroup was statistically significant better than that of the cN+ypN0-subgroup (94.4% versus 90.1%, p < 0.0001). In cN0 as well as cN+ disease, ypN+ had a statistically significant worse 5-year OS compared to ypN0. For hormone receptor (HR)+ human epidermal growth factor receptor 2 (HER2)-, HR+ HER2+, HR-HER2+, and triple negative disease, respectively, 5-year OS in the cN0ypN+-subgroup was 89.7%, 90.4%, 73.7%, and 53.6%, and in the cN+ypN+-subgroup 84.7%, 83.2%, 61.4%, and 48.8%. In multivariable analyses, cN+ and ypN+ disease were both associated with worse OS.

CONCLUSION: This study suggests that both cN-status and ypN-status, and molecular subtype should be considered to further improve prognostication.

ABSTRACT

Leprosy is a chronic infectious disease characterized by acute inflammatory episodes that affect the skin and peripheral nerves and can develop progressive and irreversible disabilities and deformities. In addition, drug therapy and physiotherapy offer resources and techniques capable of mitigating the consequences of neural lesions, but neural lesions can occur before, during, and even after drug treatment. Thus, new treatments are needed. Photobiomodulation (PBM) might be a promissor therapy since it aims to reduce the inflammatory process and restore motor and sensory functions in the affected area. This study aims to compare the evolution of neural status, pain, and functionality in patients with leprosy and neuritis after a physiotherapeutic protocol and PBM treatment. This was a randomized controlled clinical trial that analyzed a group of patients receiving a physiotherapeutic protocol (PPG) and another receiving physiotherapeutic protocol associated with PBM (PLG) (wavelength 904 nm, potency 70 mW, time per point 9 s). Our results showed when evaluating functional capacity limitations with the SALSA scale, the PLG patients improved from moderate to mild limitations. On the other hand, the PPG remained as moderate limitations. Also, the PLG showed a significant reduction in pain on the VAS scale. The neurological assessment showed that PLG improved palpation of the median, radial, and peroneal nerves. In the strength test, PLG patients improved in the 5th finger abduction and ankle dorsiflexion. Assessing sensitivity, it was identified an improvement in PLG for the ulnar nerve and tibial nerve. All those changes were statistically significant when compared to the PPG patients. Finally, the PLG patients improved disabilities, identified by the neurological assessment of the eyes, hands, and feet. In conclusion, this study demonstrated that combining a physiotherapeutic protocol with PBM treatment effectively improved functional status and reduced pain in leprosy patients.

ABSTRACT

BACKGROUND: While recognized as a key HIV prevention strategy, preexposure prophylaxis (PrEP) availability and accessibility are not well documented globally. We aimed to describe PrEP drug registration status and the availability of PrEP services across HIV care sites participating in the International epidemiology Databases to Evaluate AIDS (IeDEA) research consortium.

METHODS: We used country-level PrEP drug registration status from the AIDS Vaccine Advocacy Coalition and data from IeDEA surveys conducted in 2014, 2017 and 2020 among participating HIV clinics in seven global regions. We used descriptive statistics to assess PrEP availability across IeDEA sites serving adult patients in 2020 and examined trends in PrEP availability among sites that responded to all three surveys.

RESULTS: Of 199 sites that completed the 2020 survey, PrEP was available in 161 (81%). PrEP availability was highest at sites in North America (29/30; 97%) and East Africa (70/74; 95%) and lowest at sites in Central (10/20; 50%) and West Africa (1/6; 17%). PrEP availability was higher among sites in countries where PrEP was officially registered (146/161; 91%) than where it was not (14/32; 44%). Availability was higher at health centers (109/120; 90%) and district hospitals (14/16; 88%) compared to regional/teaching hospitals (36/63). Among the 94 sites that responded to all three surveys, PrEP availability increased from 47% in 2014 to 60% in 2017 and 76% in 2020.

CONCLUSION: PrEP availability has substantially increased since 2014 and is now available at most IeDEA sites. However, PrEP service provision varies markedly across global regions.
