Postoperative complications and unanticipated healthcare encounters following mini-laparotomy vs. laparoscopic/robotic-assisted sacrocolpopexy: a comparative retrospective study.

BACKGROUND: Pelvic organ prolapse is a debilitating condition impacting lives of millions of women worldwide. Sacrocolpopexy (SCP) is considered an effective and durable surgical technique for treatment of apical prolapse. The aim of this study was to compare short-term outcomes including postoperative complications and unanticipated healthcare encounters between patients who underwent SCP with a mini-laparotomy approach compared to patients treated with laparoscopic and robotic-assisted laparoscopic SCP. METHODS: This was a retrospective cohort study including patients treated for apical prolapse at a university affiliated urogynecology practice. Patients over the age of 18 who underwent abdominal SCP between 2019 and 2023 were included. The cohort was formed into two groups: (1) Patients who underwent SCP through a mini-laparotomy incision (Mini-lap group); (2) Patients who underwent laparoscopic or robotic-assisted laparoscopic SCP (Lap/Robot group). RESULTS: A total of 116 patients were included in the final analysis. Ninety patients underwent either laparoscopic or robotic-assisted SCP, whereas 26 patients underwent SCP with a mini-laparotomy approach. Study participants exhibited a mean age of 63.1 ± 10.3 years, mean body mass index (BMI) of 25.8 ± 4.9 Kg/m2, and 77.6% of them identified as Caucasian. Upon comparison of demographic and past medical history between groups there were no statistically significant differences in age, BMI, menopausal status, race, parity or comorbid conditions. Patients in the Mini-lap group were less likely to have undergone previous abdominal surgery (11.5% vs. 50.6%, p < 0.001) and had more severe apical prolapse (stage 4 prolapse, 40% vs. 21.2%, p < 0.001) than their counterparts in the Lap/robot group. Regarding intraoperative parameters, length of surgery was significantly shorter in the Mini-lap group compared to the Lap/robot group (97.3 ± 35.0 min vs. 242.0 ± 52.6 min, p < 0.001). When focusing on the primary outcome, postoperative complications within the first 30 days after surgery, there were no differences noted between groups. Additionally, the number of unanticipated healthcare encounters, such as phone calls, clinic visits, emergency department visits, urgent care visits, readmissions and reoperations were similar between groups. CONCLUSIONS: Mini-laparotomy approach for SCP is safe with comparable intra- and postoperative complications, and unanticipated healthcare encounters compared to conventional minimally invasive methods.

Development of preeclampsia in pregnant women with white-coat hypertension: a systematic review and meta-analysis.

OBJECTIVE: Hypertensive disorders during pregnancy are a significant cause of maternal and perinatal mortality and morbidity worldwide. White coat hypertension (WCH) is a hypertensive disease characterized by an increased clinic blood pressure but normal home or workplace blood pressure. Due to variable prevalence, a subset of women with WCH may be incorrectly diagnosed with chronic hypertension, highlighting the need for accurate diagnosis. Little is known about the role of WCH in pregnancy, but a meta-analysis aims to determine whether WCH increases the likelihood of developing preeclampsia. METHODS: A systematic review and meta-analysis was conducted to determine whether there is an association between WCH and the incidence of preeclampsia in pregnant women. The search included PubMed, Embase, and Scopus databases until February 2023, using PRISMA guidelines. Pregnant women with apparent office hypertension throughout pregnancy who underwent 24-hour ambulatory blood pressure monitoring or home blood pressure monitoring were included. Meta-analysis was performed using RevMan. RESULTS: This study included 12 studies with a total of 4,672 pregnant women and found that women with WCH have a higher risk of developing preeclampsia compared to normotensive women (RR: 2.29, 95% CI [1.18,4.43], P = 0.01). However, when compared with pregnant women with gestational hypertension or chronic hypertension, women with WCH had a significantly lower risk of developing preeclampsia ((RR: 0.39, [0.20,0.80], p=0.009) and (RR: 0.41, [0.27,0.62], P<0.001), respectively). CONCLUSION: The study recommends incorporating 24-hour ABPM into clinical practice to differentiate between chronic hypertension and WCH in early pregnancy and focus on special management for those who need it. The findings may guide future research on ABPM's role in diagnosing WCH and its effects on pregnancy outcomes.

Safety and efficacy of injection of human placenta mesenchymal stem cells derived exosomes for treatment of complex perianal fistula in non-Crohn's cases: Clinical trial phase I.

BACKGROUND AND AIM: A perianal fistula is an abnormal tract that connects anal canal to skin. Current medical and surgical interventions have a high failure rate particularly in complex and refractory cases. MSC-derived exosomes have demonstrated immunomodulatory effects without the conventional complications; hence, in this study, we evaluated the safety of their application for complex perianal fistula. METHODS: Placenta-derived MSCs were cultured, and exosomes were isolated using ultracentrifugation. Exosome injections were administered in the operating room to 11 patients with complex perianal fistula (presence of fistulas for at least 1 year alongside medical and surgical treatment). The patients were followed for 6 months, and the patients were evaluated using physical examination, face-to-face interviews, and magnetic resonance imaging (MRI). RESULTS: Among 11 patients only one did not show any improvement upon physical examination. Five patients showed complete tract resolve. While the discharge was stopped in eight patients, two patients showed only reduction. None of the patients showed any acute or latent allergic reaction or injection related complications. CONCLUSION: Administration of exosomes isolated from MSCs demonstrates safety and a satisfactory therapeutic effect in treatment complex perianal fistulae; therefore, it can be a candidate for future studies and might play a significant role in treatment.

Paroxysmal hemicrania in children and adolescents: A systematic review.

OBJECTIVE: We aimed to report the accessible demographic, clinical, and radiological characteristics of reported pediatric paroxysmal hemicrania (PH). INTRODUCTION: It has been a while since PH in a child was first described. However, it is still unknown whether children's PH follows the same patterns as adults. METHODS: This study followed the latest version of PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). PubMed, Web of Science, and Scopus were searched systematically without time limitation. We included all English-language, peer-reviewed articles, including observational or interventional studies reporting PH cases in children or adolescents based on the International Classification of Headache Disorders (ICHD) criteria. Data extracted included PH class; sex; age; age of onset; frequency, duration, site, severity, and quality of pains; triggers; and autonomic and migrainous symptoms, as well as a sense of restlessness/agitation, response to treatment, laboratory investigations, imaging, comorbidity, and family history. For quality assessment, two independent reviewers (MB and VM) assessed the methodological quality of the included studies through the Joanna Briggs Institute's critical appraisal checklist. RESULTS: A total of 182 records were identified and reduced to 116 after removing duplicates. After screening, 22 articles met the inclusion criteria. Overall, the studies represented 35 children or adolescents with PH. We found a boy-to-girl ratio of 1.125:1. Onset occurred at a broad range of 1 to 14 years old. The mean age of onset among reported cases in children and adolescents was 6.5 years, while the mean age of diagnosis was 8.2 years. [Correction added on 22 August 2022, after first online publication: In the preceding sentence, 6.3 and 7.9 years were changed to 6.5 and 8.2 years, respectively.] The attacks' frequency and duration were greatly varied. Left-sided pain occurred twice as often as right-sided pain. The characteristics of the pain were usually severe in intensity. In nearly all of the cases, it was accompanied by ipsilateral cranial autonomic features. While most attacks were spontaneous, there were some common triggers. The physical examination, electroencephalogram, and brain magnetic resonance imaging had normal findings. Almost all patients benefited from indomethacin and showed complete responses to treatment, while some needed combination treatment of indomethacin with other medications. CONCLUSION: Although pediatric-onset PH has similar features to adult-onset PH, there are some challenges with ICHD criteria for younger children that limit the ability to confidently assign a diagnosis. Moreover, owing to concomitant migrainous features, PH may be confused with migraine in children and adolescents.

Cesarean Scar Pregnancy: Results of Treatment Using a Double-Balloon Cervical Ripening Catheter.

Background: Being considered a life-threatening condition, cesarean scar pregnancy (CSP) leads to loss of fertility, severe bleeding, and even maternal mortality. We intended to assess the effect of double-balloon cervical ripening catheter insertion on CSP termination before nine weeks of gestation. Method: All participants were diagnosed CSP by abdominal and transvaginal ultrasound. The cases were treated with a sterile, double-balloon cervical ripening catheter inserted with real-time transabdominal ultrasound guidance and removed three days later. The control group consisted of patients treated with systemic methotrexate with or without fetal reduction. Results: Thirty-five patients were eligible for double-balloon ripening and 32 for MTX therapy; the treatment in cases failed in five of the patients. Success rate difference between two methods was insignificant (Pearson Chi-square: 0.383, p-value: 0.536). There were significant differences regarding the time to normal menstruation (OR: 1.303) and the thickness of the myometrium after surgery (OR: 4.721), but there was no significant difference in the time resolve of either ß-HCG or residue of pregnancy. Conclusion: Double-balloon cervical ripening insertion yields acceptable results for terminating CSP. This strategy does not cause bleeding and even prevents it with its tamponade properties. Additionally, this treatment is minimally invasive simple with low morbidity.

Structured Workshop for Repair of High-Grade Perineal Lacerations Among Obstetrics and Gynecology Residents, The Need for Repetition and Retraining.

Objective: The objective of this study was to evaluate the effectiveness of structured workshops in improving the knowledge and skills of obstetrics and gynecology residents for repairing high-grade perineal lacerations. Materials and methods: This quasi-experimental multicenter study evaluated the baseline knowledge of obstetrics and gynecology residents using an online patient-management problem (PMP) tool. After the initial evaluation, a workshop was conducted using sponge models to teach the practical technique for repairing high-grade perineal lacerations, including external and internal anal sphincter repair. The residents' knowledge was reassessed by PMP exams at 3 and 6 months after the workshop, and the scores were compared to the baseline statistics. Result: Eighty residents participated in the study, including 26, 22, and 32 at the first, second, and third-year levels of residency, respectively. The total PMP scores significantly improved after three months of the workshop, with an increasing total score from 15.5 (baseline) to 31.3 (p = 0.027) (range of total score from - 63 to + 52). The senior residents performed better before and after three months of the intervention. However, in the six-month follow-up, the total PMP score of all residents decreased to 12.3 with no significant difference with pre-education scores at all levels. Similar significant results were also reported for each PMP question at all levels of residency. Conclusion: The study found that obstetrics and gynecology residents had substandard knowledge in repairing perineal lacerations. Although the training workshop significantly increased residents' knowledge, its effectiveness diminished over time, indicating a need for continuous or periodic training. Supplementary Information: The online version contains supplementary material available at 10.1007/s13224-023-01792-6.

Comparing the effectiveness of letrozole versus methotrexate for treatment of ectopic pregnancy: A randomized controlled trial.

OBJECTIVE: To evaluate the efficacy of two different regimens of Letrozole, an aromatase inhibitor, in the management of ectopic pregnancy compared to methotrexate. STUDY DESIGN: This randomized controlled trial was conducted on 88 women diagnosed with ectopic pregnancy with a baseline level of serum beta-human chorionic gonadotropin under 3000 mIU/mL between June 30, 2023, and December 30, 2023, at the Department of Obstetrics and Gynecology of the Vali-e-Asr Hospital affiliated with Tehran University of Medical Sciences. Participants were allocated into either methotrexate (n = 43), 5-day course Letrozole (n = 24), or 10-day course Letrozole (n = 21) treatments. The methotrexate group received a single dose of 50 mg/m2 dosage intramuscular methotrexate. The 5-day Letrozole group received a 2.5 mg Letrozole tablet three times daily for 5 days, whereas the 10-day Letrozole group received a 2.5 mg Letrozole tablet twice daily for 10 days. The primary outcome was the treatment response, defined as the achievement of a negative serum beta-human chorionic level without the need for additional methotrexate treatment or surgery. The secondary outcomes were the need for additional methotrexate dose or laparoscopic surgery intervention. The trial protocol was prospectively registered in ClinicalTrials.gov with code NCT05918718. RESULTS: The treatment response rates in methotrexate, 5-day Letrozole, and 10-day Letrozole groups were 76.7 %, 75.0 %, and 90.5 %, respectively, with no significant differences between the groups (P-value = 0.358). A total of 10 (23.3 %) patients from the methotrexate group, 3 (12.5 %) from the 5-day Letrozole group, and 2 (9.5 %) from the 10-day Letrozole group required an additional methotrexate dose, with no significant differences between the groups (P-value = 0.307). Furthermore, only 3 (12.5 %) patients, all from the 5-day Letrozole group, were suspected of tubal rupture and underwent surgery (P-value = 0.016). CONCLUSION: Our findings suggest Letrozole as a safe alternative to methotrexate in treating stable ectopic pregnancies, with a favorable treatment response rate. However, there is still a need for future larger studies to determine the applicability of Letrozole in the EP management. Also, the non-significant higher effectiveness of the 10-day Letrozole regimen than the 5-day Letrozole group underscores the need for future research to determine the optimal Letrozole regimen for the management of ectopic pregnancy.

Enhanced antibacterial activity of porous chitosan-based hydrogels crosslinked with gelatin and metal ions.

Addressing the increasing drug resistance in pathogenic microbes, a significant threat to public health, calls for the development of innovative antibacterial agents with versatile capabilities. To enhance the antimicrobial activity of non-toxic biomaterials in this regard, this study focuses on novel, cost-effective chitosan (CS)-based hydrogels, crosslinked using gelatin (GEL), formaldehyde, and metallic salts (Ag+, Cu2+, and Zn2+). These hydrogels are formed by mixing CS and GEL with formaldehyde, creating iminium ion crosslinks with metallic salts without hazardous crosslinkers. Characterization techniques like FTIR, XRD, FESEM, EDX, and rheological tests were employed. FTIR analysis showed metal ions binding to amino and hydroxyl groups on CS, enhancing hydrogelation. FESEM revealed that freeze-dried hydrogels possess a crosslinked, porous structure influenced by various metal ions. Antibacterial testing against gram-negative and gram-positive bacteria demonstrated significant bacterial growth inhibition. CS-based hydrogels containing metal ions showed reduced MIC and MBC values against Staphylococcus aureus (0.5, 8, 16 µg/mL) and Escherichia coli (1, 16, 8 µg/mL) for CS-g-GEL-Ag+, CS-g-GEL-Cu2+, and CS-g-GEL-Zn2+. MTT assay results confirmed high biocompatibility (84.27%, 85.24%, 84.96% viability at 10 µg/mL) for CS-based hydrogels towards HFF-1 cells over 48 h. Therefore, due to their non-toxic nature, these CS hydrogels are promising for antibacterial applications.

Methotrexate as the first-line treatment of unruptured tubular ectopic pregnancies with high initial human chorionic gonadotropin levels: A retrospective cohort.

Objectives: To evaluate the effectiveness of the first-line medical management with Methotrexate (MTX) in the treatment of patients with stable tubal Ectopic Pregnancies (EPs) and varying ranges of Beta-Human Chorionic Gonadotropin (ß-HCG) levels. Materials and methods: In this retrospective cohort study, we reviewed the medical records of a total of 184 patients with the diagnosis of tubal EP, who received MTX as their first-line treatment. Patients with a baseline ß-HCG< 4800 mIU/mL received single-dose MTX (n = 136) and those with an initial ß-HCG≥ 4800 mIU/mL underwent the double-dose MTX regimen (n = 48). The treatment success was determined by evaluating the reported weekly ß-HCG levels of the patients. Results: Baseline ß-HCG and mass size in the single-dose group were 1895.1 ± 1463.4 mIU/mL and 2.2 ± 1.1 cm, respectively, compared to 17,867.6 ± 31,870.5 mIU/mL and 2.3 ± 1.1 cm in the double-dose group. Treatment duration was 30.6 ± 16.9 days for single dose and 41.0 ± 27.0 days for double dose, with additional MTX in 27.2% and 12.5% in respective groups. Single dose achieved a 92.6% success rate, and double dose, 81.3%, without serious adverse effects. No significant effects were seen for either baseline ß-HCG and mass size on the treatment success rates of both groups (p-value>0.05). However, the presence of Fetal Heart Rate (FHR) was associated with poorer responses only in the single-dose group (p-value=0.034). Conclusions: Medical management with MTX shows promise as a first-line treatment for tubal EPs with ß-HCG> 2000, suggesting a potential reassessment of existing guidelines in light of this emerging evidence. However, further research seems crucial in this field.

Exploring the metabolomics profile of frailty- a systematic review.

Background: Frailty is a multifaceted geriatric syndrome characterized by an increased vulnerability to stressful events. metabolomics studies are valuable tool for better understanding the underlying mechanisms of pathologic conditions. This review aimed to elucidate the metabolomics profile of frailty. Method: This systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) 2020 statement. A comprehensive search was conducted across multiple databases. Initially, 5027 results were retrieved, and after removing duplicates, 1838 unique studies were subjected to screening. Subsequently, 248 studies underwent full-text screening, with 21 studies ultimately included in the analysis. Data extraction was performed meticulously by two authors, and the quality of the selected studies was assessed using the Critical Appraisal Skills Program (CASP) checklist. Results: The findings revealed that certain Branched-chain amino acids (BCAAs) levels were lower in frail subjects compared to robust subjects, while levels of glutamate and glutamine were higher in frail individuals. Moreover, sphingomyelins and phosphatidylcholines (PC) displayed a decreasing trend as frailty advanced. Additionally, other metabolic derivatives, such as carnitine, exhibited significant associations with frailty. These metabolites were primarily interconnected through biochemical pathways related to the tricarboxylic acid and urea cycles. Notably, frailty was associated with a decrease in metabolic derivatives, including carnitine. Conclusion: This study underscores the intricate relationship between essential metabolites, including amino acids and lipids, and their varying levels in frail individuals compared to their robust counterparts. It provides a comprehensive panel of metabolites, shedding light on their potential associations with frailty and expanding our understanding of this complex syndrome.

Association between pre-diabetes or diabetes and cognitive impairment in a community-dwelling older population: Bushehr Elderly Health (BEH) program.

Background: Persistent uncontrolled hyperglycemia is recognized as one of the risk factors for cognitive disorders. Accordingly, both type 1 and type 2 diabetes may predispose individuals to cognitive impairment, particularly in cases where glycemic control is insufficient. The objective of this comprehensive study is to separately assess cognitive dysfunctions in diabetic and non-diabetic older adults. Methods: This cross-sectional study is part of phase 2 of the Bushehr elderly health program (BEHP). Cognitive function was evaluated using the Mini-cog and categorical verbal fluency tests (CFTs). Patients were classified as non-diabetics, pre-diabetics, or diabetics based on the diagnostic criteria for diabetes mellitus (DM). To compare the means of the two groups, we utilized the t-test or the Mann-Whitney test. Additionally Multivariable logistic regression models were used to determine the association between pre-diabetes or DM and cognitive impairment. Results: Out of 1533 participants, 693 (45.2%) were identified as having cognitive impairment. The average hemoglobin A1C was higher in participants with cognitive impairment compared to those without cognitive impairment. (5.8 ± 1.6% vs. 5.5 ± 1.4%, P = 0.004). Furthermore, the mean blood glucose levels were found to be more elevated in cases of cognitive impairment (108.0 ± 47.4 mg/dL vs. 102.1 ± 0.35 mg/dL, P = 0.002). After adjusting for age, gender, body mass index (BMI), waist circumference, amount of physical activity, and smoking, the multivariable logistic regression model, declared an association between diabetes and cognitive impairment (OR = 1.48, P = 0.003). In addition, older patients, females, widows, and individuals with elevated LDL-Cs and those with high blood pressure were found to be more vulnerable to cognitive impairment. Conclusion: The Bushehr Elderly Health Program (BEHP) study revealed that individuals affected with cognitive impairment may exhibit higher levels of HbA1c. This suggests a positive correlation between elevated HbA1c and cognitive impairment.

Diagnostic Performance of Ultrasonography for Identification of Small Bowel Obstruction; a Systematic Review and Meta-analysis.

Introduction: Small bowel obstruction (SBO) is known as a common cause of acute abdominal complaints in the emergency department (ED). The modality of choice for the diagnosis of SBO has not yet been established. This systematic review and meta-analysis aimed to investigate the accuracy of ultrasonography for the diagnosis of SBO. Methods: Systematic search was performed on five electronic databases including Medline, Scopus, Web of Sciences, Embase, and Cochrane Library, and the retrieval period was from the inception of each database to November 2023. The quality of the included studies were investigated using the Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2). The pooled values of diagnostic characteristics for ultrasonography were estimated using meta-Disc and Stata statistical software. Results: Twenty-one studies with a total of 1977 patients were included in the meta-analysis. The pooled estimate for sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR), and area under the summary ROC curve of ultrasonography for diagnosing SBO were 0.93 (95% CI: 0.91-0.95), 0.8 (95% CI: 0.77-0.83), 5.69 (95% CI: 3.64-8.89), 0.1 (95% CI: 0.07-0.16), 83.51 (95% CI: 18.12-182.91) and 0.96, respectively. Conclusion: The findings of this meta-analysis showed that the utilization of ultrasonography holds promise as a diagnostic imaging for SBO with high accuracy. However, additional worldwide studies are essential to get more evidence on the value of ultrasonography for the diagnosis of SBO.

Incidence and Outcomes Associated with Menopausal Status in COVID-19 Patients: A Systematic Review and Meta-analysis.

OBJECTIVE: Menopause causes several changes in the body that may affect the response to COVID -19. We aimed to investigate the possible association between menopausal status and incidence and outcomes in COVID-19 patients. METHODS: Combinations of keywordsCOVID-19, menopause, and estrogen were used to search the PubMed, Embase, Web-of-Science, and Scopus databases for articles reporting the incidence and outcomes of COVID-19 (discharge, length-of-admission, intensive care, or mortality) in premenopausal women, available through December 29, 2022. Data from studies comparing the incidence of COVID-19 infection with the age-matched male population were pooled and meta-analyzed using a random-effects model. RESULTS: Overall, 1,564 studies were retrieved, of which 12 were finally included in the systematic review to compare disease outcomes, and 6 were meta-analyzed for the incidence of COVID-19 in premenopausal and postmenopausal women. All studies reported better COVID-19-associated outcomes in premenopausal women compared with postmenopausal women. After adjusting for confounding factors, three studies found better outcomes in postmenopausal women, and two found no association between menopausal status and COVID-19 outcomes. Our meta-analysis found a higher incidence of COVID-19 infection among premenopausal women than postmenopausal women, when compared with age-matched men (odds ratio = 1.270; 95% confidence interval: 1.086-1.486; p = 0.003). CONCLUSION: The incidence of COVID-19 was significantly higher in premenopausal women than in postmenopausal women when compared with age-matched men. Although premenopausal women may have more favorable COVID-19-associated outcomes, the presumed preventive effect of estrogens on the incidence and related outcomes of COVID-19 in premenopausal women cannot be proven at present. Further longitudinal studies comparing pre- and post-menopausal women are required to provide further insight into this matter.

OBJETIVO: A menopausa causa diversas alterações no corpo que podem afetar a resposta ao COVID-19. Nosso objetivo foi investigar a possível associação entre o status da menopausa e a incidência e os resultados em pacientes com COVID-19. MéTODOS: Combinações de palavras-chave COVID-19, menopausa e estrogênio foram usadas para pesquisar os bancos de dados PubMed, Embase, Web-of-Science e Scopus para artigos relatando a incidência e os resultados do COVID-19 (alta, tempo de internação, tratamento intensivo cuidados ou mortalidade) em mulheres na pré-menopausa, disponível até 29 de dezembro de 2022. Dados de estudos comparando a incidência de infecção por COVID-19 com a população masculina da mesma idade foram agrupados e meta-analisados usando um modelo de efeitos aleatórios. RESULTADOS: No geral, 1.564 estudos foram recuperados, dos quais 12 foram finalmente incluídos na revisão sistemática para comparar os resultados da doença e 6 foram meta-analisados para a incidência de COVID-19 em mulheres na pré e pós-menopausa. Todos os estudos relataram melhores resultados associados ao COVID-19 em mulheres na pré-menopausa em comparação com mulheres na pós-menopausa. Após o ajuste para fatores de confusão, três estudos encontraram melhores resultados em mulheres na pós-menopausa e dois não encontraram associação entre o status da menopausa e os resultados do COVID-19. Nossa meta-análise encontrou uma maior incidência de infecção por COVID-19 entre mulheres na pré-menopausa do que mulheres na pós-menopausa, quando comparadas com homens da mesma idade (odds ratio = 1,270; intervalo de confiança de 95%: 1,086­1,486; p = 0,003). CONCLUSãO: A incidência de COVID-19 foi significativamente maior em mulheres na pré-menopausa do que em mulheres na pós-menopausa quando comparadas com homens da mesma idade. Embora as mulheres na pré-menopausa possam ter resultados mais favoráveis associados ao COVID-19, o efeito preventivo presumido dos estrogênios na incidência e nos resultados relacionados ao COVID-19 em mulheres na pré-menopausa não pode ser comprovado no momento. Mas estudos longitudinais comparando mulheres pré e pós-menopausa são necessários para fornecer mais informações sobre este assunto.

A rare case of prostate cancer initially presented by disseminated intravascular coagulation-related subdural hemorrhage.

BACKGROUND: Disseminated intravascular coagulation (DIC) has been reported in various solid malignancies and is a common coagulation-related complication in prostate cancer. However, DIC has been rarely reported as the initial presentation of prostate cancer. Herein, we reported a patient referring with subdural hemorrhage (SDH) and DIC with an unexplained cause who was later diagnosed with prostate cancer. CASE PRESENTATION: We presented a 68-year-old man who was referred to the hospital with a gradual deterioration of consciousness, dyspnea, and edema in the genitalia and lower limbs. His primary laboratory tests showed elevated prothrombin time (PT) and partial thromboplastin time (PTT) and a decreased fibrinogen level of 47 mg/dL [200-400 mg/dL]. The DIC score was 7, which was suggestive of DIC. Moreover, cranial imaging showed SDH. Further work-up revealed elevated prostate-specific antigen and prostate enlargement with a mass effect on the bladder with a bone lesion, which was suggestive of metastatic prostate cancer. CONCLUSION: This report highlights DIC as a possible initial presentation of an underlying malignancy, as well as the importance of treatment of underlying disease in the management of DIC. A comprehensive and systematic work-up is essential for early diagnosis in patients with DIC to avoid further complications and mortality.

Spontaneous pregnancy in a case with concurrent uterine artery embolization induced transient premature ovarian failure and Asherman syndrome: a case report.

Premature ovarian insufficiency (POI) is an uncommon cause of infertility in females characterized by hypoestrogenism. Studies have shown that uterine artery embolization (UAE) is associated with POI. Meanwhile, Asherman syndrome (AS) is a rare condition because of intracervical or intrauterine adhesions, which can happen after dilation and curettage. Both these syndromes are causes of amenorrhea and infertility. This case is of a 40-year-old woman who, after cesarean scar pregnancy and subsequent UAE because of uncontrollable vaginal bleeding, developed premature ovarian failure and AS. She underwent hysteroscopic adhesiolysis. She became pregnant with low anti-Müllerian hormone levels. Initial adhesiolysis and intervention in AS can restore uterine endometrium's ability to host a fetus. Moreover, UAE can cause POI, which might regress to some degree.

Peripheral T-cell lymphoma of the oral cavity: A case report.

BACKGROUND: Peripheral T-Cell Lymphoma Not Otherwise Specified (PTCL-NOS) is a rare type of non-Hodgkin T-cell lymphoma which frequently seen in immunocompromised individuals. It is estimated that only 2% of lymphomas are located on the buccal mucosa. In this case report, we present a 34-year-old male with a PTCL diagnosis. CASE: A 34-year-old immune-competent male presented with a buccal progressive ulcerated lesion. Histopathologic and immunohistochemical findings were compatible with PTCL-NOS and classified as stage IIEA according to the Ann Arbor staging. The patient underwent chemotherapy followed by radiotherapy. He remained disease-free after 12 months of follow-up. CONCLUSION: Although lymphoma is uncommon in the oral cavity, physicians especially dentists in ordinary dental checkups should consider persistent progressive lesions as an important differential diagnosis of lymphoma.

COVID-19, G protein-coupled receptor, and renin-angiotensin system autoantibodies: Systematic review and meta-analysis.

INTRODUCTION: There are an increasing number of reports of autoantibodies (AAbs) against host proteins such as G-protein coupled receptors (GPCRs) and the renin-angiotensin system (RAS) in COVID-19 disease. Here we have undertaken a systematic review and meta-analysis of all reports of AAbs against GPCRs and RAS in COVID-19 patients including those with long-COVID or post-COVID symptoms. METHODS: PubMed, Embase, Web of Science, and Scopus databases were searched to find papers on the role of GPCR and RAS AAbs in the presence and severity of COVID-19 or post- COVID symptoms available through March 21, 2023. Data on the prevalence of AngII or ACE, comparing AngII or ACE between COVID-19 and non-COVID-19, or comparing AngII or ACE between COVID-19 patients with different disease stages were pooled and a meta-analysed using random- or fixed-effects models were undertaken. RESULTS: The search yielded a total of 1042 articles, of which 68 studies were included in this systematic review and nine in the meta-analysis. Among 18 studies that investigated GPCRs and COVID-19 severity, 18 distinct AAbs were detected. In addition, nine AAbs were found in case reports that assessed post- COVID, and 19 AAbs were found in other studies that assessed post- COVID or long- COVID symptoms. Meta-analysis revealed a significantly higher number of seropositive ACE2 AAbs in COVID-19 patients (odds ratio = 7.766 [2.056, 29.208], p = 0.002) and particularly in severe disease (odds ratio = 11.49 [1.04, 126.86], p = 0.046), whereas AngII-AAbs seropositivity was no different between COVID-19 and control subjects (odds ratio = 2.890 [0.546-15.283], p = 0.21). CONCLUSIONS: GPCR and RAS AAbs may play an important role in COVID-19 severity, the development of disease progression, long-term symptoms COVID and post- COVID symptoms.

Assessment of the clinical outcomes and complications of hysteroscopic and laparoscopic approaches in the treatment of symptomatic isthmocele: An observational study.

OBJECTIVES: To investigate the outcomes of patients undergoing laparoscopic or hysteroscopic approaches for isthmoplasty. METHODS: A total of 99 isthmocele patients with an average age of 38.45 ± 4.72 years were included in the 2 years of this retrospective cohort study. Forty-five underwent laparoscopic and 54 underwent hysteroscopic isthmocele excision and myometrial repair. RESULTS: Pain scores were significantly higher in the hysteroscopy group before the procedure, but there were no significant pain score differences after the surgery. In 1 year of follow up, dysmenorrhea and dyspareunia were higher among hysteroscopy patients. Furthermore, hysteroscopy significantly improved postmenstrual spotting after surgery better than laparoscopy, but in the follow up, there was no significant difference between the two groups in this regard (mean rank for hysteroscopy vs. laparoscopy: 32.30 vs. 37.48, U = 418, P = 0.29). CONCLUSION: In patients with a history of infertility, ectopic pregnancy, lower gravidity, lower parity, and a lower number of cesarean sections, laparoscopic isthmoplasty is preferred over the hysteroscopic approach. Both methods have similar effects on midcycle vaginal bleeding, duration of postmenstrual spotting, and pain. However, a higher rate of dyspareunia and dysmenorrhea could be associated with hysteroscopy.

Role of autoantibodies targeting interferon type 1 in COVID-19 severity: A systematic review and meta-analysis.

Introduction: Impairment of the type I interferon (IFN-I) signaling pathway is associated with increased severity of COVID-19 disease. Here we have undertaken a systematic review and meta = analysis on the association between the severity of COVID-19 and IFN-1 autoantibodies (AAbs; aIFN-1, aIFN-α, aIFN-ω, and aIFN-ß). Methods: Four databases, including Medline [PubMed], Embase, Web of Science, and Scopus, were systematically searched to find papers on the role of aIFN-1 and its subtype AAbs in the severity of COVID-19 infection. Data on the prevalence of aIFN-1, aIFN-α, aIFN-ω, and aIFN-ß were pooled using random- or fixed-effects models. Subgroup analysis was performed based on disease severity. Odds ratios (OR) for COVID-19 disease outcome, including length of hospital stay, ICU admission and death, were calculated in relation to positive or negative plasma IFN-1 AAbs. Results: A total of 33 studies with 13023 patients were included. The overall prevalence of circulating aIFN-1, aIFN-α, and aIFN-ω AAbs was 17.8 % [13.8, 22.8], 7.2 % [4.7, 10.9], and 4.4 % [2.1, 8.6], respectively, and the overall prevalence of neutralizing aIFN-1, aIFN-α, aIFN-ω, and aIFN-ß AAbs was 7.1 % [4.9, 10.1], 7.5 % [5.9, 9.5], 8.0 % [5.7, 11.1] and 1.2 % [0.4, 3.5], respectively. Circulating aIFN-α (OR = 4.537 [2.247, 9.158]), neutralizing aIFN-α (O = 17.482 [8.899, 34.342]), and neutralizing aIFN-ω (OR = 12.529 [7.397, 21.222]) were significantly more frequent in critical/severe patients than in moderate/mild patients (p < 0.001 for all). Anti-IFN-1 was more common in male subjects (OR = 2.248 [1.366, 3.699], p = 0.001) and two COVID-19 outcomes including ICU admission (OR = 2.485 [1.409, 4.385], p = 0.002) and death (OR = 2.593 [1.199, 5.604], p = 0.015) occurred more frequently in patients with positive anti-IFN-1.Conclusion: aIFN-1 and its subtypes AAbs are associated with severe and critical COVID-19 disease and may be a predictive marker for a poor prognosis, particularly in men.
