RESUMO
Background: Vitamin D is necessary to develop healthy lungs and other organs early in life. Most infants born before 28 weeks' gestation have low vitamin D levels at birth and a limited intake during the first month. Enteral vitamin D supplementation is inexpensive and widely used. The appropriate supplementation regimen for extremely preterm infants is controversial, and the effect of different regimens on their blood levels and outcomes is unclear. Methods: Randomized, blinded comparative effectiveness trial to compare two vitamin D supplementation regimens for inborn infants <28 weeks gestation or <1000 grams birth weight at a large academic center in the United States.Infants are stratified by birth weight and randomized within 96 hours after birth to either routine supplementation (400 IU/day with established feedings) or increased supplementation (800 IU/day with any feedings) during the first 28 days after birth.We hypothesize that the higher and early vitamin D dose (800 IU/d with early feeding) compared to placebo plus routine dose (400 IU/d with established feeding) will substantially increase total 25-hydroxyvitamin D3 levels measured as state-of-art at one month, reduce respiratory support at 36 weeks' postmenstrual age (on an ordinal scale predictive of later adverse outcomes) and improve or at least not worsen other important secondary outcomes. The infants in the study will follow up at 22-26 months' corrected age (~2 years) with blinded certified examiners to evaluate neurodevelopmental outcomes.The sample size of a minimum of 180 infants provides >90% power to detect a >95% posterior probability of a 33% increase in serum 25-hydroxy vitamin D3 and >80% power to detect a >80% posterior probability of a relative risk decrease of 20% of reducing respiratory support by intention-to-treat Bayesian analyses using a neutral prior probability. Discussion: Our study will help clarify the uncertain relationship of vitamin D supplementation and its associated serum metabolites to clinical outcomes of extremely preterminfants. Confirmation of our hypotheses would prompt reconsideration of the supplementation regimens used in extremely preterm infants and justify a large multicenter study to verify the generalizability of the results.

RESUMO
PURPOSE: There is a lack of evidence for treatment of some conditions including complication management, suboptimal initial weight loss, recurrent weight gain, or worsening of a significant obesity complication after one anastomosis gastric bypass (OAGB). This study was designed to respond to the existing lack of agreement and to provide a valuable resource for clinicians by employing an expert-modified Delphi consensus method. METHODS: Forty-eight recognized bariatric surgeons from 28 countries participated in the modified Delphi consensus to vote on 64 statements in two rounds. An agreement/disagreement among ≥ 70.0% of the experts was regarded to indicate a consensus. RESULTS: A consensus was achieved for 46 statements. For recurrent weight gain or worsening of a significant obesity complication after OAGB, more than 85% of experts reached a consensus that elongation of the biliopancreatic limb (BPL) is an acceptable option and the total bowel length measurement is mandatory during BPL elongation to preserve at least 300-400 cm of common channel limb length to avoid nutritional deficiencies. Also, more than 85% of experts reached a consensus on conversion to Roux-en-Y gastric bypass (RYGB) with or without pouch downsizing as an acceptable option for the treatment of persistent bile reflux after OAGB and recommend detecting and repairing any size of hiatal hernia during conversion to RYGB. CONCLUSION: While the experts reached a consensus on several aspects regarding revision/conversion surgeries after OAGB, there are still lingering areas of disagreement. This highlights the importance of conducting further studies in the future to address these unresolved issues.

Herein, we investigated the anti-amoebic activity of phosphonium-chloride-based deep eutectic solvents against pathogenic Acanthamoeba castellanii of the T4 genotype. Deep eutectic solvents are ionic fluids composed of two or three substances, capable of self-association to form a eutectic mixture with a melting point lower than each substance. In this study, three distinct hydrophobic deep eutectic solvents were formulated, employing trihexyltetradecylphosphonium chloride as the hydrogen bond acceptor and aspirin, dodecanoic acid, and 4-tert-butylbenzoic acid as the hydrogen bond donors. Subsequently, all three deep eutectic solvents, denoted as DES1, DES2, DES3 formulations, underwent investigations comprising amoebicidal, adhesion, excystation, cytotoxicity, and cytopathogenicity assays. The findings revealed that DES2 was the most potent anti-amoebic agent, with a 94% elimination rate against the amoebae within 24 h at 30 °C. Adhesion assays revealed that deep eutectic solvents hindered amoebae adhesion to human brain endothelial cells, with DES2 exhibiting 88% reduction of adhesion. Notably, DES3 exhibited remarkable anti-excystation properties, preventing 94% of cysts from reverting to trophozoites. In cytopathogenicity experiments, deep eutectic solvent formulations and dodecanoic acid alone reduced amoebae-induced human brain endothelial cell death, with DES2 showing the highest effects. Lactate dehydrogenase assays revealed the minimal cytotoxicity of the tested deep eutectic solvents, with the exception of trihexyltetradecylphosphonium chloride, which exhibited 35% endothelial cell damage. These findings underscore the potential of specific deep eutectic solvents in combating pathogenic Acanthamoeba, presenting promising avenues for further research and development against free-living amoebae.

Gastroesophageal reflux disease (GERD) is frequently seen in the Western population. Laparoscopic anti-reflux surgery (LARS) is effective in managing this condition. Obesity is strongly associated with GERD, and with the rising rate of obesity, there is, therefore, a concurrently increasing frequency of LARS performed. We aim to review the outcomes of LARS in patients with obesity, including the recurrence of GERD symptoms and peri-operative complications. A systematic review and meta-analysis were performed for articles from June 1992 to June 2022. The literature was reviewed for outcomes of LARS in patients with obesity (BMI≥30). Eligibility criteria included specific BMI, study design, type of surgery, and outcomes. The recurrence of symptoms and peri-operative complications were assessed. Thirty-one studies were thoroughly reviewed. Nine studies (five retrospective and four prospective) were selected for meta-analysis using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) flow, which included 1,499 patients with obesity and 5,521 without. Laparoscopic Nissen fundoplication was the most common procedure performed. The recurrence of symptoms was significantly lower in patients without obesity (p=0.0001). There was no statistically significant difference between patients with and without obesity in peri-operative complications, re-intervention, and early return to theatres. A higher recurrence rate of GERD symptoms post-LARS was reported in patients with obesity. Further research is required to decrease such risks and propose different methods, such as weight loss prior to surgery or Roux-en-Y (R&Y) gastric bypass. Risks and benefits should be considered by clinicians prior to offering LARS to patients with obesity.
RESUMO
It was a descriptive cross-sectional study to determine the frequency and risk factors of tracheomalacia in patients undergoing thyroidectomy. One hundred and forty-nine patients underwent thyroidectomy at MTI-Khyber Teaching Hospital Peshawar between 1st January 2021 and 1st March 2022. The frequency of post-thyroidectomy tracheomalacia and possible associated factors were determined. The inclusion criteria were patients of either gender, between 18 to 70 years fulfilling criteria of clinically diagnosed cases of thyroid disorders who underwent subtotal, hemi, near or total thyroidectomy for their respective thyroid diseases. Post-thyroidectomy tracheomalacia was recorded in 18 patients (12.1%): Seventeen patients were aged less than 30 (p-value 0.038) and 14 (77.8%) patients had a duration of surgery > three hours (p-value <0.001). Young female patients with multinodular goitre who had a longer duration of surgery developed post-thyroidectomy tracheomalacia more frequently. Hence, the incidence of post-thyroidectomy tracheomalacia can be markedly reduced with proper preoperative assessment and postoperative measures. Key Words: Thyroid gland, Thyroid disorders, Tracheomalacia, Thyroidectomy.

Metabolic and bariatric surgery (MBS) is widely considered the most effective option for treating obesity, a chronic, relapsing, and progressive disease. Recently, the American Society of Metabolic and Bariatric Surgery (ASMBS) and the International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO) issued new guidelines on the indications for MBS, which have superseded the previous 1991 National Institutes of Health guidelines. The aim of this study is to establish the first set of consensus guidelines for selecting procedures in Class I and II obesity, using an Expert Modified Delphi Method. In this study, 78 experienced bariatric surgeons from 32 countries participated in a two-round Modified Delphi consensus voting process. The threshold for consensus was set at an agreement or disagreement of ≥ 70.0% among the experts. The experts reached a consensus on 54 statements. The committee of experts reached a consensus that MBS is a cost-effective treatment option for Class II obesity and for patients with Class I obesity who have not achieved significant weight loss through non-surgical methods. MBS was also considered suitable for patients with Type 2 diabetes mellitus (T2DM) and a body mass index (BMI) of 30 kg/m2 or higher. The committee identified intra-gastric balloon (IGB) as a treatment option for patients with class I obesity and endoscopic sleeve gastroplasty (ESG) as an option for patients with class I and II obesity, as well as for patients with T2DM and a BMI of ≥ 30 kg/m2. Sleeve gastrectomy (1) and Roux-en-Y gastric bypass (RYGB) were also recognized as viable treatment options for these patient groups. The committee also agreed that one anastomosis gastric bypass (OAGB) is a suitable option for patients with Class II obesity and T2DM, regardless of the presence or severity of obesity-related medical problems. The recommendations for selecting procedures in Class I and II obesity, developed through an Expert Modified Delphi Consensus, suggest that the use of standard primary bariatric endoscopic (IGB, ESG) and surgical procedures (SG, RYGB, OAGB) are acceptable in these patient groups, as consensus was reached regarding these procedures. However, randomized controlled trials are still needed in Class I and II Obesity to identify the best treatment approach for these patients in the future.

OBJECTIVES: Intraoperative frozen-section evaluation is a valuable technique for detecting positive margins intraoperatively for oral squamous cell carcinoma. We conducted this study to determine the diagnostic accuracy of frozen section in detecting margin status and the effect of tumor grade and stage on diagnostic accuracy. RESULTS: A total of 251 biopsy-proven cases of oral squamous cell carcinoma were included in this study. The tissue specimen resected during surgery was sent to the laboratory for frozen section evaluation. The frozen section results were then compared with the permanent section results to determine the sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy. The mean age of the patients included in the study was 51.65 ± 10.03 years, with male predominance (55.4%). The overall sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy of frozen section were 88.81%, 94.84%, 95.20%, 88.10%, and 91.63%, respectively. We conclude that frozen section is a useful technique in determining the margin status intraoperatively in oral cancers, with high diagnostic accuracy. Moreover, certain clinical parameters such as age, gender, disease duration, and tumor stage and grade appear to affect the diagnostic accuracy of frozen section.

The development of different imaging modalities of the prostate has significantly improved tumor detection, patient risk stratification, and quality of care.Among these, multiparametric magnetic resonance imaging (mp-MRI) has emerged as the most sensitive tool.It is useful in the diagnosis, localization, risk stratification, and staging of clinically significant prostate cancer, PCa. As a result, mp-MRI of the prostate is recommended as the initial diagnostic test for men with suspected PCa. A multidisciplinary approach is crucial in the diagnosis and management of prostate cancer and mp-MRI plays a fundamental role in this scenario.While many aspects of image quality certainly fall within the purview of radiology, it is important to recognize that urologists must also be attentive to imaging quality when utilizing mp-MRI to facilitate PCa management. We present our viewpoint as urologists on how image quality impacts the management of men diagnosed with PCa andattempt to identify the factors that impact mp-MRI image quality, consequences of poor image quality, and finally suggestions for improvements.

Introduction: Right-sided infective endocarditis (IE) in non-intravenous drug users is a rare finding. IE of the tricuspid valve is considered an important but uncommon complication in patients with a recent history of obstetric and gynecological procedures. Case presentation: We report a case of a 28-year-old female with IE of the tricuspid valve with a prior history of dilatation and curettage. The echocardiography revealed two mobile vegetation in the septal leaflet of the tricuspid valve with severe eccentric tricuspid regurgitation. Blood culture was positive for Staphylococcus aureus. The patient was started on intravenous (i.v.) antibiotics with supportive treatments and improved over the days. Clinical discussion: Infection can get access to the venous system via pelvic veins after the septic obstetric and gynecological procedure and subsequently to the right side of the heart. Different studies have highlighted the role of prophylactic antibiotics in significantly reducing post-abortal infections. In our patient, the disease was diagnosed on the basis of clinical, echocardiographic, and blood culture findings, and the patient responded well to i.v. antibiotics and supportive care under close monitoring in the coronary care unit. Conclusion: It is important for healthcare providers to be aware of the risk factors and symptoms associated with right-sided IE for early diagnosis and treatment. Appropriate antibiotic prophylaxis and adherence to sterile techniques can help to prevent IE.
RESUMO
Abstract Medicinal plants play a vital role in the human health care system of tribal communities and in the treatment of various gynecological problems. This study is an effort to document important medicinal flora used for the treatment of gynecological problems by indigenous people living in a tribal region near the Pak-Afghan border. The main objective of the study was to establish a clear profile of indigenous knowledge and practices from the unexplored tribal territory. Data were collected through semi-structured interviews and group discussions. The data were analyzed through Use Value and Factor of Informant Consensus. A total of 52 medicinal plants were recorded from the area; the most widely accepted were Withania somnifera (L.) Dunal (94 Use Value), Foeniculum vulgare Mill. (93 Use Value), Prunus domestica L. (91 Use Value), Myrtus communis L. (91 Use Value), Cannabis sativa L. (91 Use Value) and Nigella sativa L. (90 Use Value). A high consensus factor was recorded for menses-related problems (0.95). The root was the main part used (23% plants), followed by the leaves (20% plants), whole plant (18% plants), fruit (18% plants), and seed (13% plants). A total of 21 plants were used to treat menses-related problems, followed by sexual problems (ten plants), leucorrhea (nine plants), gastric problems (seven plants) and amenorrhea (seven plants). Knowledge related to ethnogynecological treatments is restricted to midwives and traditional healers. In conclusion, the documented flora that is particularly important to medicinal plants may be researched in the future to discover new pharmaceutical, neutraceutical and other pharmacological agents against gynecological complaints.
