Using decapsulated local brine shrimp cysts on feeding common carp larvae in hatcheries.

The current study aims at using non-hatchable artemia eggs of local origin and making use of these eggs by decapsulating and presenting them as food for the larvae of the Cyprinus carpio as a source of animal protein with high nutritional value instead of throwing them away. The results showed that the second parameter (A2) was highly significant at the level (P≤0.05) in the growth rates of the larvae that were fed on decapsulated artemia eggs alone, and it was better than the two control parameters (A1), in which the larvae were fed with feed designated for Cyprinus carpio fish. It also outperformed the third parameter (A3), in which the feed was mixed with artemia eggs with 50% decapsulation, which also outperformed the control parameter with high significance at the same level (P≤0.05).

Analysis of attitudes and practices toward gastroesophageal reflux disease among the general population of Pakistan.

Aim: Gastro-esophageal reflux disease (GERD) is a growing health concern. Methods: In this cross-sectional study, participants' knowledge, attitude and practice toward GERD were assessed using a questionnaire. Results: In our study of 411 participants, 92.5% knew about GERD. Correctly identified risk factors were smoking (62.3%), fatty food (84.2%), spicy food (91.2%) and meal timing (80.8%). Identified symptoms were burning sensation (92.2%) and regurgitation (81.0%). 43.6% of participants were unaware of GERD's complications. Only 46.2% would seek medical advice for feeling full after eating, but 85% would for severe symptoms. 88.7 and 86.8% of participants showed willingness to amend diet and lifestyle. Conclusion: General population has knowledge regarding GERD and its risk factors but poor attitude and practices toward the condition.

What is this summary about?: This summary presents the findings of a survey conducted to gauge people's understanding, attitudes and behaviors concerning gastroesophageal reflux disease (GERD). GERD is a condition involving the movement of stomach contents back into the esophagus or mouth, which can lead to the development of symptoms or complications. Common risk factors associated with the emergence of GERD symptoms, such as heartburn and the regurgitation of stomach contents into the oropharynx, include smoking, consumption of fatty and spicy foods and meal timing. While people are aware of these risk factors and the signs of GERD, many do not take proactive steps to seek medical assistance or make lifestyle changes. The goal of this study is to assess people's knowledge, attitudes and practices regarding GERD. What were the results & what do they mean?: In Pakistan, most people have good knowledge of GERD, but there's still a knowledge gap with important public health implications. Greater awareness and education are needed to improve GERD management and health outcomes for those affected. Who is this article for?: The authors of the original article developed this summary to help patients, caregivers, patient advocates, healthcare professionals, policymakers and insurance providers to understand the results of their study.

Diffusion MRI Metrics Characterize Postoperative Clinical Outcomes After Surgery for Cervical Spondylotic Myelopathy.

BACKGROUND AND OBJECTIVES: Advanced diffusion-weighted MRI (DWI) modeling, such as diffusion tensor imaging (DTI) and diffusion basis spectrum imaging (DBSI), may help guide rehabilitation strategies after surgical decompression for cervical spondylotic myelopathy (CSM). Currently, however, postoperative DWI is difficult to interpret, owing to signal distortions from spinal instrumentation. Therefore, we examined the relationship between postoperative DTI/DBSI-extracted from the rostral C3 spinal level-and clinical outcome measures at 2-year follow-up after decompressive surgery for CSM. METHODS: Fifty patients with CSM underwent complete clinical and DWI evaluation-followed by DTI/DBSI analysis-at baseline and 2-year follow-up. Clinical outcomes included the modified Japanese Orthopedic Association score and comprehensive patient-reported outcomes. DTI metrics included apparent diffusion coefficient, fractional anisotropy, axial diffusivity, and radial diffusivity. DBSI metrics evaluated white matter tracts through fractional anisotropy, fiber fraction, axial diffusivity, and radial diffusivity as well as extra-axonal pathology through restricted and nonrestricted fraction. Cross-sectional Spearman's correlations were used to compare postoperative DTI/DBSI metrics with clinical outcomes. RESULTS: Twenty-seven patients with CSM, including 15, 7, and 5 with mild, moderate, and severe disease, respectively, possessed complete baseline and postoperative DWI scans. At 2-year follow-up, there were 10 significant correlations among postoperative DBSI metrics and postoperative clinical outcomes compared with 3 among postoperative DTI metrics. Of the 13 significant correlations, 7 involved the neck disability index (NDI). The strongest relationships were between DBSI axial diffusivity and NDI (r = 0.60, P < .001), DBSI fiber fraction and NDI (rs = -0.58, P < .001), and DBSI restricted fraction and NDI (rs = 0.56, P < .001). The weakest correlation was between DTI apparent diffusion coefficient and NDI (r = 0.35, P = .02). CONCLUSION: Quantitative measures of spinal cord microstructure after surgery correlate with postoperative neurofunctional status, quality of life, and pain/disability at 2 years after decompressive surgery for CSM. In particular, DBSI metrics may serve as meaningful biomarkers for postoperative disease severity for patients with CSM.

Disseminated Sarcocystis miescheriana infection in a finisher pig in Grenada.

Sarcocystis miescheriana infection is an important cause of carcass condemnation during meat inspection. The infection can cause morbidity and mortality in domestic pigs. In this study, an 8-month-old finisher pig was presented to a local abattoir for slaughter. Multiple white nodular lesions affecting the meat were observed, resulting in the condemnation of the carcass. Consequently, half of the carcass was submitted to the necropsy diagnostic laboratory in the School of Veterinary Medicine for further evaluation. Grossly, all superficial and deep muscle groups had severe multifocal macrocysts (3 mm × 2 mm × 1 mm) on the surface and extending deep into the skeletal musculature. Histopathology revealed moderate multifocal granulomatous and eosinophilic myositis with intralesional degenerated and intact parasites. Sample genomic DNA sequence analysis of the 18S RNA gene showed 100% identity to S. miescheriana in the GenBank. This is the first report of S. miescheriana in Grenada, West Indies.

Diagnostic Accuracy of Non-invasive Tests Versus Arthroscopy in Anterior Cruciate Ligament (ACL) Injuries.

BACKGROUND: The knee joint assessment to detect anterior cruciate ligament (ACL) injury after trauma involves clinical examination and radiography. The gold standard method is doing arthroscopy. We did this study seeking to evaluate the effectiveness of other non-invasive diagnostic methods, including the Anterior Drawer test, Lachman test and magnetic resonance imaging (MRI) in detecting ACL tears after trauma, compared to the reference standard method (the arthroscopy). METHODOLOGY: This descriptive cross-sectional study was conducted in the Orthopaedic Department of the Khyber Teaching Hospital, Peshawar, for six months. A total of 86 participants with knee injuries fulfilling the inclusion criteria were recruited for the study. Mechanism of injury, side of injury and body weight were recorded. The Anterior Drawer test and Lachman test for ACL injury were performed by orthopaedic surgeons with at least five years of post-fellowship experience in orthopaedic surgery. Sensitivities, specificities and accuracy of the clinical tests and MRI were calculated. RESULTS: The statistical analysis revealed that the mean age of participants was 35.73 (SD 12.7) years, with a range from 18 to 55 years. Among the participants, 67 (77.91%) were male and 19 (22.09%) were female. The side of injury was predominantly right in 50 (58.14%) and left in 36 (41.86%) participants. Road traffic accidents (RTAs) were the leading cause of knee injury, accounting for 63.95% (55) of cases, followed by sports injuries at 23.26% (20). Regarding diagnostic accuracy, MRI showed a sensitivity of 98.57%, specificity of 87.50% and diagnostic accuracy of 96.51% in detecting ACL tears. The Lachman test demonstrated a sensitivity of 90%, specificity of 87.5% and diagnostic accuracy of 89.53% compared to arthroscopy. Similarly, the anterior Drawer test exhibited a sensitivity of 88.57%, specificity of 87.50% and diagnostic accuracy of 88.37% against the gold standard of arthroscopy. These findings underscore the effectiveness of these diagnostic modalities in identifying ACL injuries. CONCLUSIONS: All three tests (MRI, Lachman test and anterior Drawer test) can be used for the diagnosis of anterior cruciate ligament injury with optimal results.

Initial Experience With Robotic Liver Resection in the United States.

BACKGROUND: This study's aim was to show the feasibility and safety of robotic liver resection (RLR) even without extensive experience in major laparoscopic liver resection (LLR). METHODS: A single center, retrospective analysis was performed for consecutive liver resections for solid liver tumors from 2014 to 2022. RESULTS: The analysis included 226 liver resections, comprising 127 (56.2%) open surgeries, 28 (12.4%) LLR, and 71 (31.4%) RLR. The rate of RLR increased and that of LLR decreased over time. In a comparison between propensity score matching-selected open liver resection and RLR (41:41), RLR had significantly less blood loss (384 ± 413 vs 649 ± 646 mL, P = .030) and shorter hospital stay (4.4 ± 3.0 vs 6.4 ± 3.7 days, P = .010), as well as comparable operative time (289 ± 123 vs 290 ± 132 mins, P = .954). A comparison between LLR and RLR showed comparable perioperative outcomes, even with more surgeries with higher difficulty score included in RLR (5.2 ± 2.7 vs 4.3 ± 2.5, P = .147). The analysis of the learning curve in RLR demonstrated that blood loss, conversion rate, and complication rate consistently improved over time, with the case number required to achieve the learning curve appearing to be 60 cases. CONCLUSIONS: The findings suggest that RLR is a feasible, safe, and acceptable platform for liver resection, and that the safe implementation and dissemination of RLR can be achieved without solid experience of LLR.

Comparative and Predictive Significance of Serum Leptin Levels in Non-alcoholic Fatty Liver Disease.

Background Non-alcoholic fatty liver disease (NAFLD) has emerged as the single most common chronic non-viral liver disease. The burden of the disease on healthcare-providing services has increased tremendously. Although a liver biopsy is the most authentic laboratory investigation for scoring the disease progression, it is an invasive technique. Researchers are vigorously working to find alternate markers for the scoring purpose. Despite the importance and association of leptin with metabolic syndrome and its related disorders, there have been relatively fewer studies on serum leptin and its association with NAFLD. Objective This study aimed to investigate variations in serum leptin levels between subjects with and without fibrosis in NAFLD and to assess the predictive value of serum leptin levels in NAFLD subjects. Materials and methods The study comprised 130 NAFLD subjects from two tertiary care hospitals in Lahore along with 86 healthy controls that were age, gender, and BMI matched with the subjects. Based on the NAFLD fibrosis score (NFS), the subjects were divided into two sub-groups, subjects with simple steatosis and those with fibrosis. Fasting serum leptin, glucose, and insulin levels were measured using enzyme-linked immunosorbent assay (ELISA). The Kruskal-Wallis test was applied to find differences between the three groups and Fisher's exact test for categorical comparison. To assess the predictive value of serum leptin for steatosis and fibrosis in NAFLD subjects, receiver operation characteristic (ROC) curve analysis was implemented. Results The difference in serum leptin level was statistically highly significant (p-value <0.001), with leptin levels of 10 (17.1) ng/mL among controls, 20.5 (21) ng/mL in simple steatosis, and 21 (28.6) ng/mL in fibrosis. The area under the ROC curve was 0.67 and 0.52 for steatosis and fibrosis, respectively. The cut-off value of 12.2 ng/mL showed 70% sensitivity and 50% specificity for steatosis, while at a threshold of 18 ng/mL, leptin demonstrated 40% sensitivity and specificity for fibrosis. Conclusion In conclusion, this study found that serum leptin levels are higher in NAFLD subjects compared to healthy controls, and it is a good independent predictor for the detection of liver steatosis.

"Empty Cyst Sign" Appearance of CSF-Venous Fistula on Digital Spinal Myelography.

Cerebrospinal fluid venous fistulas (CSF-VFs) are an uncommon, yet increasingly recognized, cause of spontaneous intracranial hypotension.1-5 The workup involves magnetic resonance imaging (MRI) of the brain with and without contrast and MRI of the neuroaxis without contrast before dynamic myelography, either computed tomography or digital subtraction.6 The present case of an older woman with symptomatic intracranial hypotension is notable for the specific appearance of CSF-VFs on digital spinal myelography (Video 1). Among her numerous perineural cysts, it was the "disappearing" or "empty" cyst from which the fistula originated. The diagnosis was made using a second lateral fluoroscopy view, not typically used in digital spinal myelography, which demonstrated emptying of contrast from the T6 perineural cyst into the segmental vein at this level, or the "empty cyst sign." The patient then underwent transvenous onyx embolization with resolution of her orthostatic headaches and improvement of contrast-enhanced MRI of the brain with the Bern score decreasing from 7 to 0 at 3 months of follow-up.7 Because transvenous embolization of CSF-VFs is a relatively new procedure, the long-term outcomes of the procedure are not yet known.

Variations in the genomic profiles and clinical behavior of meningioma by racial and ethnic group.

OBJECTIVE: The influence of socioeconomic factors on racial disparities among patients with sporadic meningiomas is well established, yet other potential causative factors warrant further exploration. The authors of this study aimed to determine whether there is significant variation in the genomic profile of meningiomas among patients of different races and ethnicities and its correlation with clinical outcomes. METHODS: The demographic, genomic, and clinical data of patients aged 18 years and older who had undergone surgery for sporadic meningioma between September 2008 and November 2021 were analyzed. Statistical analyses were performed to detect differences across all racial/ethnic groups, as were direct comparisons between Black and non-Black groups plus Hispanic and non-Hispanic groups. RESULTS: This study included 460 patients with intracranial meningioma. Hispanic patients were significantly younger at surgery (53.9 vs 60.2 years, p = 0.0006) and more likely to show symptoms. Black patients had a higher incidence of anterior skull base tumors (OR 3.2, 95% CI 1.7-6.3, p = 0.0008) and somatic hedgehog mutations (OR 5.3, 95% CI 1.6-16.6, p = 0.003). Hispanics were less likely to exhibit the aggressive genomic characteristic of chromosome 1p deletion (OR 0.28, 95% CI 0.07-1.2, p = 0.06) and displayed higher rates of TRAF7 somatic driver mutations (OR 2.96 95% CI 1.1-7.8, p = 0.036). Black patients had higher rates of recurrence (OR 2.6, 95% CI 1.3-5.2, p = 0.009) and shorter progression-free survival (PFS; HR 2.9, 95% CI 1.6-5.4, p = 0.002) despite extents of resection (EORs) similar to those of non-Black patients (p = 0.745). No significant differences in overall survival were observed among groups. CONCLUSIONS: Despite similar EORs, Black patients had worse clinical outcomes following meningioma resection, characterized by a higher prevalence of somatic hedgehog mutations, increased recurrence rates, and shorter PFS. Meanwhile, Hispanic patients had less aggressive meningiomas, a predisposition for TRAF7 mutations, and no difference in PFS. These findings could inform the care and treatment strategies for meningiomas, and they establish the foundation for future studies focusing on the genomic origins of these observed differences.

Seroprevalence of Hepatitis B virus and human immunodeficiency virus co-infection in pregnant women from Osun State, Nigeria.

INTRODUCTION: Hepatitis B virus and human immunodeficiency virus (HBV/HIV) co-infection is a global health concern due to its significant impact on morbidity and mortality. Reports of HBV/HIV co-infections are increasing in Nigeria, but information on the disease burden in pregnant women and its implications on the fetus is scarce. This study aimed to determine the prevalence of HBV/HIV co-infection in pregnant women. In addition, the study identified the risk factors for the disease in pregnant women attending antenatal clinics in Osun State, Nigeria. METHODOLOGY: We collected plasma samples from 303 consenting pregnant women and used enzyme-linked immunosorbent assay (ELISA) to test for HBV (HBsAg) and HIV I/II antigens. We obtained demographic and risk factor data on HBV and HIV transmission using a structured questionnaire. RESULTS: Our analysis revealed a prevalence of 3.96% for HBV/HIV co-infection in pregnant women. Bivariate analysis indicated a history of blood transfusion, oral or anal sex, and multiple sexual partners may be associated with an increased likelihood of HBV/HIV co-infection in pregnant women. After adjusting for other variables in multivariate analysis, none of these risk factors were significant at the 5% level. In contrast, formal education was a potential preventive factor in this population. CONCLUSIONS: Our study provides valuable information on the disease burden of HBV/HIV co-infection in pregnant women in Osun State, Nigeria, highlighting the importance of routine screening for HBV and HIV during antenatal care and emphasizing the importance of implementing preventive measures to reduce the morbidity and mortality associated with HBV/HIV co-infection.

Sigmoid colon pseudotumor of actinomycosis: a rare case.

Actinomycosis is a chronic suppurative infection caused by gram-positive bacteria, Actinomyces, which commonly colonize the oral cavity, urogenital tract and gastrointestinal tract. It causes opportunistic infection where the mucosal barrier is compromised and is often misdiagnosed as malignancy. We report a case of a 58-year-old female with severe abdominal pain and a palpable tender mass in the left lower quadrant. Computed tomography scan with contrast showed thickening of the transverse, descending to sigmoid colon wall and intense contrast enhancement resembling colitis with mesenteritis. At laparotomy, we found an adherent mass involving sigmoid colon with adjacent small bowel and peritoneum. We decided to perform adhesiolysis and Hartmann procedure. The culture result was negative, whereas the biopsy of sigmoid colon revealed characteristic sulfur granules of actinomycosis colony. Intravenous antibiotic combination of ceftazidime and metronidazole was administered for 14 days followed by complete resolution of symptoms. Histopathological and bacteriological examinations are keys to diagnose actinomycosis. Patients require long-term antibiotic therapy, but surgery is often required because preoperative diagnosis is difficult. Main novel aspects?: We presented the rare case of intra-abdominal actinomycosis in IndonesiaThe case was challenging to diagnose pre-operatively based on physical examination andExploratory laparotomy revealed pseudotumor mimicking advanced stage of colon neoplasm.

Pleural effusion due to lymphangiomatosis and the role of sirolimus: A case report.

Introduction: Lymphangiomatosis is a rare abnormal proliferation of lymphatic vessels involving multiple organs like the brain, lung, heart, spleen, liver, and bones. Lymphangiomas constitute 5.6% of all benign tumors in infancy and adulthood. Case presentation: We report a case of a young lady who presented with constitutional symptoms and progressive dyspnea. Her medical history is significant for muco-cutaneous albinism, diffuse hemangiomas of the bone and viscera, and consumptive coagulopathy status post-splenectomy. After initial investigations, she was found to have right-sided pleural effusion. Pleural fluid analysis indicated chylothorax. She had multiple drainages of the pleural fluid done, and afterward, ligation of the right thoracic duct was performed with a trial of sirolimus, which improved her chylothorax. Clinical discussion: Several case reports have reported positive outcomes with sirolimus in the treatment of lymphangiomatosis. However, larger controlled studies are needed to confirm these findings. Conclusion: Sirolimus is promising as a medical treatment for diffuse pulmonary lymphangiomatosis.

Comparison of Pedicle Coagulation Hemorrhoidectomy With LigaSure Versus Conventional Milligan Morgan Hemorrhoidectomy in Reducing Post-operative Pain: A Randomized Controlled Trial.

Background Hemorrhoids refer to the abnormal enlargement of the anal cushions. They are a common anorectal problem with a prevalence of 5% in the general population aged greater than 40 years. The objective of this study was to compare Milligan-Morgan open hemorrhoidectomy with pedicle ligation with LigaSure (Medtronic, Dublin, Ireland) in terms of postoperative pain on day 1 and day 7. It is important to assess the technique that is associated with lower postoperative pain because both of these techniques are still practiced in the developing world. Methods It was a randomized controlled trial conducted in the Department of Surgery, Rawalpindi, Pakistan. A total of 100 patients were selected and were allotted into the two groups by lottery method. Patients aged from 15 to 60 years who presented with symptomatic third and fourth-degree hemorrhoids were included after taking informed consent. Patients who had a previous or concomitant anorectal disease, patients who had undergone previous surgery for hemorrhoids, and those who were anesthetically unfit for surgery (American Society of Anesthesiologists (ASA) class 3 or above) were excluded from the study. Pain was assessed using the Visual Analogue scale (VAS). Data was entered and analyzed using SPSS v. 23.0 (IBM Corp., Armonk, USA). Chi-square tests were applied. P-value <0.05 was taken as statistically significant. Results Out of 100 patients, 68 (68%) were males while 32 (32%) were females. The mean age was 40.56±9.24 years. Postoperative pain at day 1 was 9.24±0.51 in the Milligan-Morgan group while that in the LigaSure group was 8.44±0.64 (p<0.0001). Postoperative pain at day 7 was 5.00±0.85 in the Milligan-Morgan group while it was 3.04±1.08 in the LigaSure group (p<0.0001). Conclusion LigaSure is a newer technique that helps to reduce complications as compared to other traditional hemorrhoidectomy procedures. Many patients avoid hemorrhoidectomy as it is associated with painful postoperative recovery. Pedicle coagulation with LigaSure was better than conventional Milligan-Morgan hemorrhoidectomy in terms of reducing the mean postoperative pain on 1st day and 7th day. Reducing the postoperative pain helps in greater patient satisfaction and lesser requirement of analgesia among patients of 3rd and 4th-degree hemorrhoids undergoing hemorrhoidectomy.

Type 1 Diabetes Impairs Endothelium-Dependent Relaxation Via Increasing Endothelial Cell Glycolysis Through Advanced Glycation End Products, PFKFB3, and Nox1-Mediated Mechanisms.

BACKGROUND: Type 1 diabetes (T1D) is a major cause of endothelial dysfunction. Although cellular bioenergetics has been identified as a new regulator of vascular function, whether glycolysis, the primary bioenergetic pathway in endothelial cells (EC), regulates vascular tone and contributes to impaired endothelium-dependent relaxation (EDR) in T1D remains unknown. METHODS: Experiments were conducted in Akita mice with intact or selective deficiency in EC PFKFB3 (6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase 3), the main regulator of glycolysis. Seahorse analyzer and myography were employed to measure glycolysis and mitochondrial respiration, and EDR, respectively, in aortic explants. EC PFKFB3 (Ad-PFKFB3) and glycolysis (Ad-GlycoHi) were increased in situ via adenoviral transduction. RESULTS: T1D increased EC glycolysis and elevated EC expression of PFKFB3 and NADPH oxidase Nox1 (NADPH oxidase homolog 1). Functionally, pharmacological and genetic inhibition of PFKFB3 restored EDR in T1D, while in situ aorta EC transduction with Ad-PFKFB3 or Ad-GlycoHi reproduced the impaired EDR associated with T1D. Nox1 inhibition restored EDR in aortic rings from Akita mice, as well as in Ad-PFKFB3-transduced aorta EC and lactate-treated wild-type aortas. T1D increased the expression of the advanced glycation end product precursor methylglyoxal in the aortas. Exposure of the aortas to methylglyoxal impaired EDR, which was prevented by PFKFB3 inhibition. T1D and exposure to methylglyoxal increased EC expression of HIF1α (hypoxia-inducible factor 1α), whose inhibition blunted methylglyoxal-mediated EC PFKFB3 upregulation. CONCLUSIONS: EC bioenergetics, namely glycolysis, is a new regulator of vasomotion and excess glycolysis, a novel mechanism of endothelial dysfunction in T1D. We introduce excess methylglyoxal, HIF1α, and PFKFB3 as major effectors in T1D-mediated increased EC glycolysis.

Frailty and postoperative outcomes in brain tumor patients: a systematic review subdivided by tumor etiology.

PURPOSE: Frailty has gained prominence in neurosurgical oncology, with more studies exploring its relationship to postoperative outcomes in brain tumor patients. As this body of literature continues to grow, concisely reviewing recent developments in the field is necessary. Here we provide a systematic review of frailty in brain tumor patients subdivided by tumor type, incorporating both modern frailty indices and traditional Karnofsky Performance Status (KPS) metrics. METHODS: Systematic literature review was performed using PRISMA guidelines. PubMed and Google Scholar were queried for articles related to frailty, KPS, and brain tumor outcomes. Only articles describing novel associations between frailty or KPS and primary intracranial tumors were included. RESULTS: After exclusion criteria, systematic review yielded 52 publications. Amongst malignant lesions, 16 studies focused on glioblastoma. Amongst benign tumors, 13 focused on meningiomas, and 6 focused on vestibular schwannomas. Seventeen studies grouped all brain tumor patients together. Seven studies incorporated both frailty indices and KPS into their analyses. Studies correlated frailty with various postoperative outcomes, including complications and mortality. CONCLUSION: Our review identified several patterns of overall postsurgical outcomes reporting for patients with brain tumors and frailty. To date, reviews of frailty in patients with brain tumors have been largely limited to certain frailty indices, analyzing all patients together regardless of lesion etiology. Although this technique is beneficial in providing a general overview of frailty's use for brain tumor patients, given each tumor pathology has its own unique etiology, this combined approach potentially neglects key nuances governing frailty's use and prognostic value.

Doctors' Perception Regarding Bariatric Surgery and Major Barriers in Referral of Morbidly Obese Patients for Surgery in Khyber Pakhtunkhwa.

INTRODUCTION: Obesity is on the rise worldwide and has emerged as a global health concern. It has presented itself as the leading cause of morbidity, disability, and healthcare utilization. Bariatric surgery is a viable treatment option that offers sustained weight loss and improvement in comorbidities. The aim of this study is to determine the perception of doctors regarding bariatric surgery and the major barriers to the referral of morbidly obese for surgery. METHOD: This study is a cross-sectional descriptive study conducted from November 1, 2022, to December 31, 2022. It involved prospective data collection through online questionnaires filled by doctors practicing in Peshawar. The sampling technique was non-probability convenience-based sampling. The sample size was 152. Doctors from all age groups and both genders were included in our study. Non-consenting doctors and those who were practicing bariatric surgery were excluded. Data were analyzed using a statistical package for social sciences (SPSS) version 25.0 (IBM Inc., Armonk, NY). Categorical variables have been presented as frequencies and percentages. Numerical variables have been presented as mean ± SD. RESULTS: A total of 152 doctors participated in our research study; 92 were physicians and 60 were surgeons. The majority of our study participants' patient load per week was >75. Around 47% believed bariatric surgery was a valuable tool in the treatment of morbid obesity. The most commonly reported barrier to referral was surgical complications or side effects (28.9%). CONCLUSION: The study concluded that the awareness regarding bariatric and metabolic surgery remains flimsy among the doctor community. Most of the physicians were unaware of the benefits of the surgical management of obesity. They also had doubts regarding the safety of the procedure. We need proper utilization of awareness strategies to overcome these barriers.

The clinical and genomic features of seizures in meningiomas.

Meningiomas are the most common central nervous system tumors. Although these tumors are extra-axial, a relatively high proportion (10%-50%) of meningioma patients have seizures that can substantially impact the quality of life. Meningiomas are believed to cause seizures by inducing cortical hyperexcitability that results from mass effect and cortical irritation, brain invasion, or peritumoral brain edema. In general, meningiomas that are associated with seizures have aggressive features, with risk factors including atypical histology, brain invasion, and higher tumor grade. Somatic NF2 mutated meningiomas are associated with preoperative seizures, but the effect of the driver mutation is mediated through atypical features. While surgical resection is effective in controlling seizures in most patients with meningioma-related epilepsy, a history of seizures and uncontrolled seizures prior to surgery is the most significant predisposing factor for persistent postoperative seizures. Subtotal resection (STR) and relatively larger residual tumor volume are positive predictors of postoperative seizures. Other factors, including higher WHO grade, peritumoral brain edema, and brain invasion, are inconsistently associated with postoperative seizures, suggesting they might be crucial in the development of an epileptogenic focus, but do not appear to play a substantial role after seizure activity has been established. Herein, we review and summarize the current literature surrounding meningioma-related epilepsy and underscore the interaction of multiple factors that relate to seizures in patients with meningioma.

Papillary Thyroid Cancer With Pituitary Gland Metastasis: A Unique Encounter.

The pituitary gland is a rare metastatic site, and thyroid cancer (TC) metastasis to the pituitary gland is immensely uncommon. We report the case of a 45-year-old male in whom pituitary metastasis (PM) discovery during the immediate postoperative period complicated the management of papillary thyroid cancer (PTC). His postoperative magnetic resonance imaging (MRI) of the pituitary lesion showed a progression in size with persistent optic nerve compression. The critical location of the pituitary lesion and the rapid progression dictated the treatment course. The pituitary lesion was non-iodine avid, and thus we opted for external beam radiation therapy (EBRT). He received 1,200 centigray (cGy) with Gamma knife radiosurgery with steroid cover. In our case, the aggressive histological and clinical variant of PTC consisted of multiple metastatic sites involving large volume pulmonary, skeletal, and chest wall lesions coupled with crucial macro metastatic pituitary mass. The patient was offered radioactive iodine to treat other iodine avid metastases in the lungs and bones and was also offered EBRT to target skeletal lesions. Systemic treatment with tyrosine kinase inhibitor was also discussed with the patient. Our case encourages clinicians to exercise vigilance and a high index of suspicion for PM when a patient with any pre-existing cancer presents with visual disturbance, cranial nerve deficit, or symptoms suggestive of hormonal deficiency. It also highlights the importance of involving endocrinologists before performing any surgery on the endocrine organs to ascertain the integrity of the endocrine function of the glands.

Clinical and genomic differences in supratentorial versus infratentorial NF2 mutant meningiomas.

OBJECTIVE: Mutations in NF2 are the most common somatic driver mutation in sporadic meningiomas. NF2 mutant meningiomas preferentially arise along the cerebral convexities-however, they can also be found in the posterior fossa. The authors investigated whether NF2 mutant meningiomas differ in clinical and genomic features based on their location relative to the tentorium. METHODS: Clinical and whole exome sequencing (WES) data for patients who underwent resection of sporadic NF2 mutant meningiomas were reviewed and analyzed. RESULTS: A total of 191 NF2 mutant meningiomas were included (165 supratentorial, 26 infratentorial). Supratentorial NF2 mutant meningiomas were significantly associated with edema (64.0% vs 28.0%, p < 0.001); higher grade-i.e., WHO grade II or III (41.8% vs 3.9%, p < 0.001); elevated Ki-67 (55.0% vs 13.6%, p < 0.001); and larger volume (mean 45.5 cm3 vs 14.9 cm3, p < 0.001). Furthermore, supratentorial tumors were more likely to harbor the higher-risk feature of chromosome 1p deletion (p = 0.038) and had a larger fraction of the genome altered with loss of heterozygosity (p < 0.001). Infratentorial meningiomas were more likely to undergo subtotal resection than supratentorial tumors (37.5% vs 15.8%, p = 0.021); however, there was no significant difference in overall (p = 0.2) or progression-free (p = 0.4) survival. CONCLUSIONS: Supratentorial NF2 mutant meningiomas are associated with more aggressive clinical and genomic features as compared with their infratentorial counterparts. Although infratentorial tumors have higher rates of subtotal resection, there is no associated difference in survival or recurrence. These findings help to better inform surgical decision-making in the management of NF2 mutant meningiomas based on location, and may guide postoperative management of these tumors.

Dermabrasion Versus Microneedling in Transplantation of Autologous Noncultured Melanocyte-Keratinocyte Cell Suspension in Patients With Vitiligo.

BACKGROUND: Autologous noncultured melanocyte-keratinocyte transplantation is one of the procedures used to treat stable vitiligo with varying reported results. Recipient site preparation is one of the variables that could affect repigmentation outcomes. OBJECTIVE: To assess the effectiveness of transplanting autologous melanocyte-keratinocyte suspension in patients with stable vitiligo and to compare recipient site preparation using dermabrasion versus microneedling. METHODS: From March 2020 to September 2022, this randomized comparative study included 40 patients with 40 stable vitiligo lesions managed by suspension transplants of melanocytes. Patients were divided into 2 groups: group A, where the recipient site was prepared using dermabrasion, and group B, which was done by microneedling. The assessment was performed 3 months after the treatment based on the degree of repigmentation (excellent, ≥90%; good, 50%-89%; fair, 20%-49%; and poor response, <20%). RESULTS: Both modalities resulted in effective repigmentation, but the dermabrasion group showed a statistically significant improvement and a satisfactory repigmentation rate. CONCLUSION: Autologous melanocyte transplantation is a safe and effective treatment method for stable vitiligo lesions that have not responded to other therapies. When compared with microneedling, dermabrasion produced better outcomes for recipient site preparation.
