This study aims to elucidate the recent advancements in our comprehension of the link between these conditions in the pediatric demographic, focusing on pathogenesis, incidence, diagnostic methods, and effective therapeutic strategies. MATERIAL AND METHODS A systematic review was conducted following the PRISMA 2020 guidelines, with a search of the PubMed database for eligible studies published in the ten years leading up to January 2023. RESULTS Out of 23 reports based on 16 original studies, we found a significantly higher prevalence of NAFLD in adolescents with PCOS compared to healthy controls. Factors such as increased de novo lipogenesis, alterations in gut microbiota, and a deficiency in growth differentiation factor-15 have been implicated in their pathogenesis. Additionally, novel biomarker S100A4, a clinical prediction score for hepatic steatosis in PCOS, and pharmacotherapy involving low-dose spironolactone, pioglitazone, and metformin have been proposed to enhance the management of these conditions. CONCLUSIONS A meticulous approach to the prevention, detection, and treatment of NAFLD in adolescents with PCOS is paramount to mitigate further complications. The study underlines the need for ongoing research to refine our understanding and management of these interconnected metabolic disorders.</p>","PeriodicalId":18276,"journal":{"name":"Medical Science Monitor : International Medical Journal of Experimental and Clinical Research","volume":"29 ","pages":"e940398"},"PeriodicalIF":0.0,"publicationDate":"2023-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/0c/03/medscimonit-29-e940398.PMC10360446.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9857215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, accurately determining the number of axillary lymph node (ALN) metastases remains challenging. The Z0011 trial changed the axillary management strategy, eliminating the need for axillary lymph node dissection (ALND) in patients with 1-2 sentinel lymph node (SLN) metastases. Therefore, further exploration is needed to identify patients who could benefit from abemaciclib therapy. MATERIAL AND METHODS This retrospective study included cT1-2N0M0 HR+/Her2- patients with 1-2 positive SLNs who underwent ALND. Clinicopathological data were collected, and logistic regression analyses identified independent predictors for ≥4 positive ALNs. A predictive nomogram was developed, and discrimination and calibration were evaluated using the C-index and calibration curve. Clinical efficacy was assessed using decision curve analysis (DCA). RESULTS We enrolled 444 patients, with 77 (17.3%) having ≥4 positive ALNs. Independent predictors for ≥4 positive ALNs included abnormal ALN on ultrasound, mammographic calcifications, T stage, and the number of positive SLNs. The nomogram demonstrated an AUC of 0.777 (95% CI: 0.735-0.815, P<0.001), and internal validation showed good calibration and discrimination (C-index, 0.802; 95% CI: 0.779-0.824).

Robotic-assisted gait training (RAGT) offers precise control and intensive, task-specific training. The EksoNR exoskeleton shows potential in facilitating gait recovery. This study assesses the efficacy and tolerability of RAGT using EksoNR in the rehabilitation of 19 stroke patients. MATERIAL AND METHODS A prospective nonrandomized, observational study design was employed with a single group convenience sample. The study included 19 individuals post-stroke, who underwent a 4-week rehabilitation program. Baseline and post-rehabilitation assessments were conducted using selected International Classification of Functioning, Disability and Health (ICF) codes, gait exoskeleton parameters (number of steps, walking time, time of verticalization) obtained during the exoskeleton sessions, and the Timed Up and Go Test (TUG). RESULTS The study revealed statistically significant improvements in all analyzed ICF categories, except for D530 Toileting, indicating enhanced functioning. The most notable improvements in activity and participation were observed in the categories of D410 Changing basic body position (-0.84±0.60) and D450 Walking (-0.84±0.60). Additionally, gait analysis demonstrated significant enhancements in the number of steps (difference of 506.79±252.49), walking time (13.02±7.91), and time of verticalization (11.82±9.21) (p>0.001). The TUG test also showed a statistically significant improvement in mobility (p=0.005).

Human anatomy studies have identified the costoclavicular space as the area between the midpoint of the clavicle and the first rib. This space accommodates the brachial plexus, axillary arteries, and veins. Its superficial and fixed position makes it a promising option for infraclavicular brachial plexus blockage, providing a safe and reliable analgesic effect. CCB combines the benefits of real-time ultrasound visualization of the nerve block needle, avoidance of peripheral blood vessels, and targeted delivery of local anesthetics to the nerve. Consequently, it significantly reduces the associated complications of other classical approaches such as interscalene brachial plexus block (ISB), supraclavicular brachial plexus block (SCB), lateral sagittal infraclavicular brachial plexus block (LS-ICB), and axillary brachial plexus block. These complications include phrenic paralysis, incomplete brachial plexus block, and pneumothorax. This narrative review examines the literature on brachial plexus block in the costoclavicular space, discussing the anatomical position, the procedure, clinical indications, choice of local anesthetic concentration and volume, and continuous nerve block of CCB.

Accordingly, our study aims to scrutinize the endodontic practices of pedodontists in Turkey and compare them with contemporary literature. MATERIAL AND METHODS We conducted an online survey with 15 questions that 217 Turkish pedodontists answered. The questionnaire sought information about their preferences in canal length measurement, canal sealer, irrigation solution, and other procedural decisions. Chi-square test was used to analyze the responses, with a significance level of p<0.05. RESULTS The majority of respondents were associated with universities (123 out of 217). 103 preferred rotary file sets, and 114 used apex locators for canal length measurement. Iodoform pastes (160) and sodium hypochlorite (180) were the most popular choices for canal sealers and irrigation solution, respectively. 152 participants did not prefer using rubber dam, and 186 did not favor sonic-ultrasonic activators.

MATERIAL AND METHODS We examined the expression of ATM, NFKB1, SOD2, INSR, and TIGAR, along with their related miRNAs using PCR, in two contexts:1 - During the three-stage visceral adipogenesis under normal glucose levels (5.5 millimoles), intermittent, and chronic hyperglycemia (30 millimoles).2 - In visceral adipose tissue from subjects (34 F, 18 M) with normal glucose metabolism, impaired fasting glucose, and type 2 diabetes mellitus. RESULTS Both chronic and intermittent hyperglycemia similarly influenced ATM, NFKB1, TIGAR, SOD2, INSR gene expression in visceral adipocytes, with corresponding changes in a few tested miRNAs (eg, let-7g-5p, miR-145-5p, miR-21-5p).
