An algorithm for the National Institute of Health Stroke Scale assessment: A multicenter, two-arm and cluster randomized study.

BACKGROUND: The NIH Stroke Scale (NIHSS) is a validated tool for assessing stroke severity, increasingly used by general practitioners in telemedicine services. Mobile apps may enhance its reliability. We aim to validate a digital platform (SPOKES) for NIHSS assessment in telemedicine and healthcare settings. METHODS: Hospitals using a telemedicine service were randomly allocated to control or SPOKES-user groups. The discrepancy between the NIHSS scores reported and those confirmed by experts was evaluated. Healthcare providers from comprehensive stroke centers were invited for interrater validation. Participants were randomized to assess the NIHSS using videos of real patients. Weighted Kappa (wk) statistics analyzed the agreement, and logistic regression determined the correlation with the congruency. RESULTS: A total of 299 telemedicine consultations from 12 hospitals were included. The difference between the NIHSS scores reported and double-checked was lower in the SPOKES group (p = 0.03), with a significantly higher level of complete agreement (72.5 % vs. 50.4 %, p = 0.005). Adoption of SPOKES was associated with complete congruency (OR 4.01, 95 %CI 1.42-11.35, p = 0.009). For interrater validation, 20 participants were considered. In the SPOKES group, almost-perfect and strong agreement occurred in 13.3 %(n = 6/45) and 84.4 %(n = 38/45) of ratings, respectively; in the control group, 6.7 %(n = 3/45) were almost-perfect, 28.9 %(n = 13/45) strong and 51 %(n = 23/45) were minimal. CONCLUSION: A free and reliable mobile application for NIHSS assessment can significantly improve interrater agreement between healthcare professionals, and between NIHSS-certified neurologists and general practitioners. Our results underscore the importance of ongoing training and education in enhancing the consistency and reliability of NIHSS scores.

On methods for radiometric surveying in radiotherapy bunkers.

Radiometric surveys in radiotherapy bunkers have been carried out in Brazil for many years, both by the same radiotherapy facility for verification of shielding as by the regulatory agency for licensing and control purposes. In recent years, the Intensity Modulated Radiation Therapy (IMRT) technique has been gradually incorporated into many facilities. Therefore, it has been necessary to consider the increased leakage component that has an important impact on the secondary walls. For that, a radiometric survey method has been used that considers an increased 'time of beam-on' for the secondary walls. In this work we discuss two methods of doing this: the first considers that this 'time of beam-on' affects the sum of the two components, leakage and scattered. In another method it is considered that only the leakage component is affected by this extended 'time of beam-on'. We compare the methods and show that for secondary walls withU= 1 the first method overestimates dose rates by important percentages and for secondary walls withU< 1 it can both overestimate or underestimate the dose rates, depending on the parameters of the project. An optimized procedure is proposed, according to the use factor (U) of the secondary wall to be measured.

Risk of ovarian hyperstimulation syndrome in women with malignancies undergoing treatment with long-acting gonadotropin-releasing hormone agonist after controlled ovarian hyperstimulation for fertility preservation: a systematic review.

Background: Fertility preservation is an important quality of life issue for women of reproductive age undergoing gonadotoxic treatment. The possibility of administering an adjuvant long-acting gonadotropin-releasing hormone agonist (GnRHa) with the aim of reducing the number of follicles susceptible to the effects of chemotherapy and thus reducing the risk of ovarian damage is considered in some international society guidelines, particularly in certain cancers such as breast cancer. Nowadays, the administration of long-acting GnRHa after controlled ovarian hyperstimulation (COH) for fertility preservation by cryopreservation of oocytes or embryos is increasingly used. However, cases of ovarian hyperstimulation syndrome (OHSS) have been reported following the use of long-acting GnRHa after COH for fertility preservation, indicating that the potential adverse effects of this treatment need to be further investigated. Objectives: The aim of this systematic review was to comprehensively characterize patients who developed OHSS after treatment with long-acting GnRHa following COH for fertility preservation. Methods: A comprehensive search of major electronic databases through January 2023 was performed. Studies reporting the use of long-acting GnRHa after COH for fertility preservation and the development of OHSS were included. Risk of bias was assessed using a modified version of the Newcastle-Ottawa scale. Results were synthesized qualitatively. Results: Three studies with five patients met the eligibility criteria. The majority of patients were diagnosed with breast cancer and all patients underwent COH for oocyte cryopreservation. OHSS occurred in all patients after administration of long-acting GnRHa. The interval between ovulation induction and administration of long-acting GnRHa thereafter ranged from 3 to 5 days. All patients were treated conservatively and recovered without complications. Conclusion: Current evidence suggests that the use of long-acting GnRHa after COH for fertility preservation may be associated with OHSS. Healthcare providers should thoroughly discuss the benefits and risks of this intervention with their patients before making a decision. Further studies are needed to fully elucidate the causal relationship between long-acting GnRHa and OHSS in this population.

Population health impact and economic evaluation of the CARDIO4Cities approach to improve urban hypertension management.

Cardiovascular disease (CVD) is the leading cause of mortality worldwide, with 80% of that mortality occurring in low- and middle-income countries. Hypertension, its primary risk factor, can be effectively addressed through multisectoral, multi-intervention initiatives. However, evidence for the population-level impact on cardiovascular (CV) event rates and mortality, and the cost-effectiveness of such initiatives is scarce as long-term longitudinal data is often lacking. Here, we model the long-term population health impact and cost-effectiveness of a multisectoral urban population health initiative designed to reduce hypertension, conducted in Ulaanbaatar (Mongolia), Dakar (Senegal), and in the district of Itaquera in São Paulo (Brazil) in collaboration with the local governments. We based our analysis on cohort-level data among hypertensive patients on treatment and control rates from a real-world effectiveness study of the CARDIO4Cities approach (built on quality of care, early access, policy reform, data and digital, Intersectoral collaboration, and local ownership). We built a decision tree model to estimate the CV event rates during implementation (1-2 years) and a Markov model to project health outcomes over 10 years. We estimated the number of CV events averted and quality-adjusted life-years gained (QALYs through the initiative and assessed its cost-effectiveness based on the costs reported by the funder using the incremental cost effectiveness ratio (ICER) and published thresholds. A one-way sensitivity analysis was performed to assess the robustness of the results. The modelled patient cohorts included 10,075 patients treated for hypertension in Ulaanbaatar, 5,236 in Dakar, and 5,844 in São Paulo. We estimated that 3.3-12.8% of strokes and 3.0-12.0% of coronary heart disease (CHD) events were averted during 1-2 years of implementation in the three cities. We estimated that over the subsequent 10 years, 3.6-9.9% of strokes, 2.8-7.8% of CHD events, and 2.7-7.9% of premature deaths would be averted. The estimated ICER was USD 748 QALY gained in Ulaanbaatar, USD 3091 in Dakar, and USD 784 in São Paulo. With that, the intervention was estimated to be cost-effective in Ulaanbaatar and São Paulo. For Dakar, cost-effectiveness was met under WHO-CHOICE standards, but not under more conservative standards adjusted for purchasing power parity (PPP) and opportunity costs. The findings were robust to the sensitivity analysis. Our results provide evidence that the favorable impact of multisector systemic interventions designed to reduce the hypertension burden extend to long-term population-level CV health outcomes and are likely cost-effective. The CARDIO4Cities approach is predicted to be a cost-effective solution to alleviate the growing CVD burden in cities across the world.

Feasibility and safety of combined laparoscopic and transvaginal oocyte retrieval in a woman with vaginal recurrence of cervical adenocarcinoma: a case report.

Introduction: Oocyte cryopreservation is an established technique for fertility preservation in women diagnosed with cancer. However, some clinical scenarios may preclude the commonly used transvaginal approach to oocyte retrieval. In such cases, a laparoscopic approach may be required. Here, we report the feasibility and safety of a combined laparoscopic and transvaginal approach for oocyte retrieval in a woman with vaginal recurrence of cervical adenocarcinoma. This approach allowed for oocyte cryopreservation prior to cancer treatment, representing a novel application in this clinical context. Methods: A 31-year-old woman with endocervical adenocarcinoma underwent laparoscopic radical hysterectomy and pelvic lymph node dissection. She presented with vaginal recurrence and was referred for fertility preservation by oocyte cryopreservation before chemotherapy and radiotherapy/brachytherapy. Ovarian stimulation was initiated with a gonadotropin antagonist protocol combined with aromatase inhibitors, and oocyte retrieval was performed with a combined laparoscopic and transvaginal approach. Results: A total of 18 oocytes were retrieved and 10 mature oocytes were cryopreserved. Peritoneal fluid cytology was negative for malignancy. The patient underwent chemotherapy and radiotherapy/brachytherapy and was disease-free after oocyte retrieval. Conclusion: The combined laparoscopic and transvaginal approach for oocyte retrieval emerges as a practical and efficacious method for fertility preservation in cases of cervical adenocarcinoma with vaginal recurrence. Further comprehensive studies are warranted to establish the reproducibility, safety, and long-term outcomes associated with this innovative approach.

Implementing a multisector public-private partnership to improve urban hypertension management in low-and middle- income countries.

BACKGROUND: Cardiovascular disease presents an increasing health burden to low- and middle-income countries. Although ample therapeutic options and care improvement frameworks exist to address its prime risk factor, hypertension, blood pressure control rates remain poor. We describe the results of an effectiveness study of a multisector urban population health initiative that targets hypertension in a real-world implementation setting in cities across three continents. The initiative followed the "CARDIO4Cities" approach (quality of Care, early Access, policy Reform, Data and digital technology, Intersectoral collaboration, and local Ownership). METHOD: The approach was applied in Ulaanbaatar in Mongolia, Dakar in Senegal, and São Paulo in Brazil. In each city, a portfolio of evidence-based practices was implemented, tailored to local priorities and available data. Outcomes were measured by extracting hypertension diagnosis, treatment and control rates from primary health records. Data from 18,997 patients with hypertension in primary health facilities were analyzed. RESULTS: Over one to two years of implementation, blood pressure control rates among enrolled patients receiving medication tripled in São Paulo (from 12·3% to 31·2%) and Dakar (from 6·7% to 19·4%) and increased six-fold in Ulaanbaatar (from 3·1% to 19·7%). CONCLUSIONS: This study provides first evidence that a multisectoral population health approach to implement known best-practices, supported by data and digital technologies, and relying on local buy-in and ownership, can improve hypertension control in high-burden urban primary care settings in low-and middle-income countries.

Effect of thyroid function on assisted reproduction outcomes in euthyroid infertile women: A single center retrospective data analysis and a systematic review and meta-analysis.

Background: The influence of thyroid-stimulating hormone (TSH) on gestational outcomes have been studied and checked whether differing TSH levels are relevant on human reproduction outcomes. International guidelines recommend TSH values <2.5 mIU/L in women trying to conceive, since values above this level are related to a higher frequency of adverse reproductive outcomes. This study aimed to evaluate whether TSH values correlate with different gestational outcomes in euthyroid infertile women without autoimmune thyroid disease. Methods: A retrospective cohort study was conducted involving 256 women who underwent in vitro fertilization (IVF) treatment. The participants were divided into two groups: TSH 0.5-2.49 mIU/L (n=211) and TSH 2.5-4.5 mIU/L (n=45). The clinical data, hormonal profiles and reproductive outcomes were compared between groups. Additionally, a systematic review with meta-analysis following the PRISMA protocol was carried out in PubMed/MEDLINE, EMBASE, and SciELO, with no time or language restrictions, for articles comparing TSH groups named "low TSH" (<2,5 mIU/L) and "high TSH" (≥2.5 mIU/L). A meta-analysis of proportions was performed with pooled estimates expressed as relative risk (RR) of events and a random effects model. Results: Age, BMI, free thyroxine levels (FT4) hormonal profile and IVF outcomes were not different between groups, neither gestational outcomes (p=0.982). Also, no difference was observed when the TSH and FT4 levels were compared between patients with positive or negative gestational outcomes (p=0.27 and p=0.376). Regarding the systematic review with meta-analysis, 17 studies from 2006 to 2022 were included, and added by this original retrospective research comprising 13.247 women undergoing IVF. When comparing the proportions of clinical pregnancy between the TSH groups, no significant difference was found (RR 0.93, 95% CI 0.80-1.08), with high between studies heterogeneity (I²: 87%; τ2: 0.0544; p<0.01). The number of deliveries was not significantly different between groups, despite a trend towards higher frequency in the high-TSH group (RR 0.96, 95% CI 0.90-1.02). Conclusion: Variation in TSH levels within the normal range was not associated with pregnancy and delivery rates in women, without autoimmune thyroid disease, who underwent IVF treatment.

Impact of blood levels of progesterone on the day of ovulation onset on clinical, laboratory and reproductive parameters of young patients undergoing assisted reproduction: a cross-sectional study.

OBJECTIVE: To assess whether there is an association between the level of progesterone on the day of administration of human chorionic gonadotropin and clinical and laboratory characteristics, in addition to the results of in vitro fertilization of patients with a good prognosis. METHODS: A cross-sectional study comprising 103 women who underwent intracytoplasmic sperm injection treatment, between November 2009 and May 2015, aged ≤35 years, with no comorbidities, with fresh embryo transfer. Data were collected from patient medical records. RESULTS: There was a weak positive correlation between the level of progesterone on the day of human chorionic gonadotropin and the number of follicles larger than 14mm (ß=0.02, p=0.001), retrieved oocytes (ß=0.01, p=0.01) and oocytes in metaphase II (MII) (ß=0.02, p=0.02); that is, the increase in progesterone level has a slight association with increased values of these variables. Body mass index was inversely correlated with progesterone level on the day of human chorionic gonadotropin (ß=-0.01, p=0.02). No association was found between the level of progesterone on the day of human chorionic gonadotropin and the protocols used for controlled ovarian stimulation, quality of transferred embryos and the pregnancy rate. CONCLUSION: There is an association between the value of progesterone on the day of human chorionic gonadotropin administration with body mass index, number of follicles larger than 14mm, number of retrieved oocytes and oocytes in metaphase II. Unlike embryo quality and pregnancy rate, which do not have a statistically significant relation with this value in the population studied.

Predictors of hemorrhagic transformation differences between patients treated or not with reperfusion therapy.

BACKGROUND: Hemorrhagic transformation (HT) is a dreaded complication in stroke patients who were treated or not with recombinant tissue plasminogen activator (tPA). There are many predictive scores of HT, but all of them included patients treated with tPA. Molecular effects of tPA and clinical aspects of eligible patients for tPA therapy may imply specific HT's risk factors. We aimed to describe HT's characteristics and risk factors in patients treated or not with tPA. METHODS: We included 1565 consecutive stroke patients admitted to a Comprehensive Stroke Center, from 2015 to 2017. All included patients underwent a follow-up neuroimaging within seven days after admission. From a logistic regression model, we derived a score based on the beta-coefficients. The accuracy of the models was attested by Receiver Operating Characteristic analysis. RESULTS: Low ASPECTS, blood glucose ≥ 180 mg/dL, tPA treatment, and cardio-aortic embolism were predictors of HT. Male sex, leukoaraiosis, and hyperdense MCA sign were associated with HT in non-treated patients. Diastolic blood pressure ≥ 105 mmHg was a risk factor only in non-treated patients. The cutoff of our predictive score of HT was higher in patients not treated with tPA (5 vs 2 points). CONCLUSIONS: High arterial blood pressure was associated with HT only in patients treated with tPA. Different cutoffs and accuracy measurements suggest that scoring systems derived from patients treated with tPA may not be efficient to predict HT in non-treated patients. Further directions indicate considering the use of reperfusion therapies to select the most accurate predictive variables of HT.

Epidemiology of Urological Cancers in Brazil: Trends in Mortality Rates Over More Than Two Decades.

BACKGROUND: Considering the socioeconomic disparities and inequalities observed in the healthcare resources among the Brazilian regions, we aimed to analyze the mortality trends of urological cancers in Brazil to identify areas with differential risks. METHODS: Deaths related to prostate (PCa), bladder (BCa), kidney (KC), penile (PeC), and testis (TCa) cancers from 1996 to 2019 were retrieved from the Mortality Information System database (Brazil). Geographic and temporal patterns were analyzed using age-standardized mortality rates (ASMRs). A joinpoint regression model was used to identify changes in the trends and calculate the average annual percentage change (AAPC) for each region. RESULTS: In Brazil, the ASMRs (per 100,000 persons/year) were 11.76 for PCa; 1.37, BCa; 1.13, KC; 0.33, and PeC; 0.26, TCa over the period. Increasing mortality trends were registered for BCa (AAPC = 0.45 in men; 0.57 in women), KC (AAPC = 2.03 in men), PeC (AAPC = 1.01), and TCa (AAPC = 2.06). The PCa mortality presented a significant reduction after 2006. The Northeast and North regions showed the highest increases in the PCa mortality. The South registered the highest ASMRs for BCa and KC, but the highest increasing trends occurred in the men from the Northeast. The North presented the highest ASMR for PeC, while the South registered the highest ASMR for TCa. CONCLUSION: Differences among regions may be partly explained by disparities in the healthcare systems. Over the study period, the North and Northeast regions presented more discrepant mortality rates. Efforts should be made to ensure access to the healthcare resources for people at risk, particularly in these regions.

Should obesity be associated with worse urinary continence outcomes after robotic-assisted radical prostatectomy? a propensity score matching analysis.

PURPOSE: To analyze the association between obesity and urinary incontinence rate in men submitted to robot-assisted radical prostatectomy (RARP) in a high-volume cancer center. MATERIALS AND METHODS: We reported 1.077 men who underwent RARP as the primary treatment for localized prostate cancer from 2013 to 2017. Patients were classified as non-obese (normal BMI or overweight) or obese men (BMI ≥30kg/m2). They were grouped according to the age, PSA level, D'Amico risk group, Gleason score, ASA classification, pathological stage, prostate volume, salvage/adjuvant radiotherapy, perioperative complications, and follow-up time. Urinary continence was defined as the use of no pads. For the analysis of long-term urinary continence recovery, we conducted a 1:1 propensity-score matching to control confounders. RESULTS: Among the obese patients, mean BMI was 32.8kg/m2, ranging 30 - 45.7kg/m2. Only 2% was morbidly obese. Obese presented more comorbidities and larger prostates. Median follow-up time was 15 months for the obese. Complications classified as Clavien ≥3 were reported in 5.6% of the obese and in 4.4% of the non-obese men (p=0.423). Median time for continence recovery was 4 months in both groups. In this analysis, HR was 0.989 for urinary continence recovery in obese (95%CI=0.789 - 1.240; p=0.927). CONCLUSIONS: Obese can safely undergo RARP with similar continence outcomes comparing to the non-obese men when performed by surgeons with a standardized operative technique. Future studies should perform a subgroup analysis regarding the association of obesity with other comorbidities, intending to optimize patient counseling.

Impact of blood levels of progesterone on the day of ovulation onset on clinical, laboratory and reproductive parameters of young patients undergoing assisted reproduction: a cross-sectional study

ABSTRACT Objective: To assess whether there is an association between the level of progesterone on the day of administration of human chorionic gonadotropin and clinical and laboratory characteristics, in addition to the results of in vitro fertilization of patients with a good prognosis. Methods: A cross-sectional study comprising 103 women who underwent intracytoplasmic sperm injection treatment, between November 2009 and May 2015, aged ≤35 years, with no comorbidities, with fresh embryo transfer.

No association was found between the level of progesterone on the day of human chorionic gonadotropin and the protocols used for controlled ovarian stimulation, quality of transferred embryos and the pregnancy rate. Conclusion: There is an association between the value of progesterone on the day of human chorionic gonadotropin administration with body mass index, number of follicles larger than 14mm, number of retrieved oocytes and oocytes in metaphase II. Unlike embryo quality and pregnancy rate, which do not have a statistically significant relation with this value in the population studied.

Evaluation of anaesthetic depth and cardiopulmonary effects of propofol infusion rate in Sapajus apella previously chemically contained with dextroketamine-midazolam.

BACKGROUND: This study evaluated the cardiopulmonary effects and anaesthetic depth induced by a propofol infusion rate of 0.8 mg/kg/min in monkeys (Sapajus apella). MATERIALS AND METHODS: Five capuchin monkeys received dextroketamine-midazolam intramuscularly. After a maximum duration of 5 min, the values of the physiological parameters were recorded, and a venous catheter was placed. After recovery from chemical restraint, the animals were anaesthetized with propofol intravenously, which was maintained for 1 h. Physiological parameters, anaesthetic depth, the time and quality of anaesthetic recovery were evaluated. RESULTS: Heart and respiratory rates, systolic blood pressure and rectal temperature during propofol infusion were lower than those during anaesthesia induction with dextroketamine-midazolam. Unconsciousness, muscle relaxation and lack of response to tail clamping were observed during propofol infusion. No animals showed excitement or vocalization during anaesthetic recovery. CONCLUSION: Propofol infusion rate of 0.8 mg/kg/min promoted surgical general anaesthesia, with transient hypotension, which showed excellent anaesthetic recovery.

Prostate Cancer Screening in Brazil: a single center experience in the public health system.

PURPOSE: Incidence and mortality of prostate cancer (PCa) are still increasing in developing countries. Limited access to the health system or more aggressive disease are potential reasons for this. Ethnic and social differences in developed countries seem to make inappropriate to extrapolate data from other centers. We aim to report the epidemiological profile of a PSA-screened population from a cancer center in Brazil. MATERIALS AND METHODS: We retrospectively selected 9.692 men enrolled in a PCa prevention program, comprising total PSA level and digital rectal examination at the first appointment, associated with complementary tests when necessary. Men aged over 40 years-old were included after shared decision-making process. Prostate biopsy (TRUS) was performed when clinically suspected for PCa. After the diagnosis, patients underwent appropriate treatment. RESULTS: TRUS was performed in 5.5% of men and PCa incidence was 2.6%. Overall ratio between number of patients who needed to be screened in order to diagnose one cancer was 38.9 patients, with 2.1 biopsies performed to diagnose a cancer. Positive predictive value (PPV) of TRUS biopsy in this strategy was 47.2%, varying from 38.5% (<50 years-old) to 60% (>80 years-old). We evidenced 70 patients (27.9%) classified as low risk tumors, 74 (29.5%) as intermediate risk, and 107 (42.6%) as high-risk disease. CONCLUSIONS: PSA-screening remains controversial in literature. In front of a huge miscegenated people and considering the big proportion of high-risk PCa, even in young men diagnosed with the disease, it is imperative to inform patients and health providers about these data particularities in Brazil.

Cost-effectiveness analysis of robotic-assisted versus retropubic radical prostatectomy: a single cancer center experience.

Prostate cancer (PCa) treatment has been greatly impacted by the robotic surgery. The economics literature about PCa is scarce. We aim to carry-out cost-effectiveness and cost-utility analyses of the robotic-assisted radical prostatectomy (RALP) using the "time-driven activity-based cost" methodology. Patients who underwent radical prostatectomy in 2013 were retrospectively analyzed in a cancer center over a 5-year period. Fifty-six patients underwent RALP and 149 patients underwent retropubic radical prostatectomy (RRP). The amounts were subject to a 5% discount as correction of monetary value considering time elapsed. Calculation of the Incremental Cost-Effectiveness Ratios (ICER) related to events avoided and the Incremental Cost-Utility Ratio (ICUR) related to "QALY saved" were performed. QALY was performed using values of utility and "disutility" weights from the "Cost-Effectiveness Analysis Registry". Hypothetical cohorts were simulated with 1000 patients in each group, based on the treatment outcomes. Total and average costs were R$1,903,671.93, and R$12,776.32 for the RRP group, and R$1,373,987.26, and R$24,535.49 for the RALP group, respectively. The costs to treat the hypothetical cohorts were R$10,010,582.35 for RRP, and R$19,224,195.90 for RALP. ICER calculation evidenced R$9,213,613.55 of difference between groups. ICUR was R$ 22,690.83 per QALY saved. Limitations were the lack of cost-effectiveness analyses related to re-hospitalization rates and complications, single center perspective, and currency-translation differences. Medical fees were not included. RALP showed advantages in cost-effectiveness and cost-utility over RRP in the long term. Despite the increased costs to the introduction of robotic technology, its adoption should be encouraged due to the gains.

Prevalence of preeclampsia and eclampsia in adolescent pregnancy: A systematic review and meta-analysis of 291,247 adolescents worldwide since 1969.

OBJECTIVE: Hypertensive disorders are among the main causes of maternal and perinatal morbidity and mortality, and the findings regarding the occurrence of preeclampsia (PE) and eclampsia (E) in adolescent pregnancy are conflicting. We performed a systematic review and meta-analysis aimed to determining the prevalence of PE and E in adolescent pregnancy considering socioeconomic and temporal characteristics. STUDY DESIGN: MEDLINE, EMBASE and SciELO databases, with no time span restrictions. Studies that reported the occurrence of PE and E in adolescent pregnancy. Study selection, data extraction and bias assessment were performed by three independent investigators. Meta-analysis techniques comprised random-effects model and double-arcsine transformation; χ1 and I2 tests were used to assess heterogeneity. Meta-regression used Hunter-Schmidt model; publication bias were assessed by funnel and Baujat plots. RESULTS: Seventy studies were included, ranging from 1969 to 2019 and comprising 30 countries and 291,247 adolescents. The overall prevalence rate of PE/E was 6.7 % (95 % CI = 5.8-7.6). Subgroup analysis revealed association of PE/E (P = 0.050) and E (P = 0.0113) with country income, and the highest prevalences were found in low-and medium-income country groups (11.5 %, 95 % CI=7.8-15.8 and 10.6 %, 95 % CI=6.05-16.2). Association of PE with publication year (P = 0.0022) was also found with an observable reduction in prevalence rate across the years. CONCLUSIONS: The findings seem to confirm that socioeconomic and demographic characteristics play a role for the risk of PE/E in adolescent pregnancy. Although the occurrence of PE has declined worldwide, the problem has broader dimensions beyond health issues.

The role of Kisspeptin levels in polycystic ovary syndrome: a systematic review and meta-analysis.

PURPOSE: Polycystic ovarian syndrome (PCOS) is a complex and not fully elucidated pathology. This prevalent endocrinopathy affects patients in reproductive age, impacts on estrogen-dependent diseases, as well as in infertility. In this context, Kisspeptin (KP) may be considered a potential biomarker for PCOS diagnosis and follow-up. Here, we aimed to verify the levels of KP in obese and non-obese patients with PCOS, their relationship with other hormones, in comparison to healthy controls. METHODS: A systematic review and meta-analysis were performed according to the PRISMA guidelines. We searched MEDLINE, EMBASE, PsycINFO, Global Health, The Cochrane Library, Health Technology Assessment Database, and Web of Science for eligible studies. A random effects model meta-analysis of standardized mean difference (SMD) was conducted and the I2 was used to assess heterogeneity. Meta-regression was conducted through mixed-effects model. RESULTS: A total of 12 studies were included, comprising 660 PCOS patients and 600 controls. The KP levels were lower in the control group (0.76: 0.17-1.35; 95% CI). In the subgroup analyses, patients were divided in non-overweight/obese (BMI < 25) and overweight/obese (BMI ≥ 25) groups. The meta-regression revealed a difference between the obese and non-obese groups (z = 2.81; p = 0.0050). CONCLUSIONS: PCOS patients showed higher KP levels than control, and obese non-PCOS patients also showed altered KP levels. All studies had poor descriptions of sample collection, pre-analytical and analytical procedures, which is critical considering structural characteristics of the KP molecule.

The Development of Cognitive and Affective Skills Through a Sexual and Reproductive Health Medical Education Unit.

INTRODUCTION: Although better medical training on sexual and reproductive health (SRH) is an unquestionable global need, and recent research has emphasized the importance of SRH education, few studies have presented alternative teaching models to conventional approaches. AIM: To examine the structure and evaluation of a curricular unit that uses an active teaching and learning strategy, and to evaluate both the cognitive and affective student learning outcomes. METHODS: This study used retrospective and cross-sectional analyses of a curricular unit with 8 weekly lessons structured into individual activities before the class, group activities monitored in class, feedback, and the development of medical empathy. MAIN OUTCOME MEASURE: Student performance was evaluated through summative and formative activities. The process was evaluated quantitatively by a questionnaire containing Likert-type and open-ended questions with speech analysis and with categorical evaluation. RESULTS: The final average of the analyzed group was 7.95 ± 0.5 on a scale of 10. Likert-type assessment (Cronbach's α = 0.86) revealed strong student adherence and, through responses to open-ended questions, positive evaluations of the proposed SRH teaching model. The Jefferson Scale of Physician Empathy showed a high index of self-reported general empathy (117.3 ± 11), with a significantly higher index for female students (P = .019) than male students; however, this gender difference disappeared after the intervention (P = .086). CONCLUSIONS: The curriculum model was developed and continuously adjusted based on grounded theory for teaching SRH and included both cognitive and affective stimuli; the results showed favorable student evaluation of the unit, and it proved feasible to implement in the time available. de Oliveira R, Montagna E, Zaia V, et al.

Real-world Adherence and Persistence with Bisphosphonate Therapy in Postmenopausal Women: A Systematic Review.

PURPOSE: Bisphosphonate therapy is a well-established and effective treatment for postmenopausal osteoporosis and the prevention of osteoporotic fracture. However, poor adherence to and poor persistence with bisphosphonate therapy may reduce its benefits. Previous studies have documented the poor rates of adherence and persistence among postmenopausal women with osteoporosis. The objective of this systematic literature review was to evaluate adherence, persistence, and the impact of adherence and persistence on fracture risk in postmenopausal women with diagnosed osteoporosis. METHODS: Articles eligible for review included observational studies of the real-world use of bisphosphonates in 23 countries and were identified by using MEDLINE, EMBASE, IMSEAR (Index Medicus for South-East Asia Region), and LILACS (Latin American and Caribbean Health Sciences Database). FINDINGS: We identified and evaluated 10 studies that assessed bisphosphonate adherence by measuring medication possession ratio (MPR), persistence, and/or the impact of adherence and persistence on fracture risk. Mean MPR at 1 year ranged from 54% to 71% in the 3 studies that reported this assessment of adherence, and 40%-85% of patients at 1 year were adherent, defined as an MPR ≥80%, in the 8 studies that reported this end point. At 1 year, rates of persistence ranged from 28% to 74%. Rates of adherence and persistence were highest with agents requiring less frequent administration and typically declined over time. Fracture rates were significantly lower among adherent women with MPRs ≥80% compared with women with MPRs <80%. IMPLICATIONS: Our results show that suboptimal adherence to and persistence with bisphosphonate therapy in postmenopausal women are common and increase the risk of fracture. Additional research is needed to identify and incorporate effective strategies for improving adherence to bisphosphonates in postmenopausal women.

Histological evaluation of sheep ovarian tissue after laparoscopic partial ovariectomy.

In the present study, there was assessment of the damage to tissue caused by partial laparoscopic ovariectomy using bipolar forceps in sheep. Fragments of ovaries of six sheep were removed using bipolar forceps by making a transverse section in the middle third of the organ via three-portals that were made using laparoscopy. The fragments were subjected to standard histological examinations and the lesions attributed to the procedure were investigated using an optical microscope and Image J software. The results were assessed using an analysis of variance and the Tukey test. All the laminae had minimal tissue damage. The mean amount of highly damaged tissue was 1.8%, and of partially damaged tissue was 5.6%. The mean total area of healthy tissue in the fragments was 94.4%. The results of the study indicate this procedure can be conducted withvery little tissue damage occurring. The use of this procedure, therefore, can be incorporated in future reproductive studies without altering the functions of the in situ ovarian tissues.
