Neutrophil gelatinase-associated lipocalin (NGAL) appears to be a promising biomarker but its levels measured from serum and urine have demonstrated varying predictive values. Our study aimed to explore the potential of NGAL as a biomarker in predicting graft dysfunction in kidney transplant patients, including live and deceased donor recipients. METHODS: A single-centered observational cohort study with live and deceased kidney recipients as participants was conducted between 2018 and 2022 at a tertiary care hospital in Southern India. Serum creatinine levels were monitored daily; creatinine reduction on day two and day seven were calculated. The recipients were categorized based on graft recovery into three groups: delayed graft function (DGF), slow graft function (SGF), or immediate graft function (IGF). Analysis of serum and urine NGAL was conducted two hours after the transplant and their predictive values were evaluated by the area under the curves (AUC) method. RESULTS: Of the 40 participants, 34 (85.0%) received their transplant from live-related donors, while six (15.0%) received kidneys from deceased donors. DGF occurred in four (10.0%) patients, SGF in 12 (30.0%), and 24 (60.0%) patients achieved IGF. Serum NGAL demonstrated higher sensitivity compared to urine NGAL. At a cut-off value of 678 ng/mL (AUC = 0.77), serum NGAL showed 90.0% sensitivity and 53.0% specificity. Urine NGAL had 70.0% sensitivity and 74.0% specificity at a cut-off value of 489 ng/mL (AUC = 0.72). CONCLUSIONS: Kidney recipients in SGF and DGF categories had elevated levels of serum and urine NGAL compared to those without IGF. Although serum NGAL showed higher sensitivity than urine NGAL in predicting graft dysfunction, both markers lacked the specificity needed for accurate predictions.

METHODS: We conducted a cross-sectional survey examining the self-reported attitudes of Omani parents about accidental injuries (poisoning, falls, burns, and drowning) at home among children younger than six and house safety measures. A total of 220 parents of children aged < 6 years, admitted to a tertiary healthcare teaching hospital, were invited to participate over a period of six months (May to November 2018). Analysis of 178 participant data was performed using SPSS, as 44 of the answered questionnaires had missing data, or were related to children over the age of six. RESULTS: Only 16.9% of the Omani families had a history of a child injury in the year before the study. Males were more injured (61.0%) and 66.0% were younger than three years at the time of injury. A door to control access to stairs was available for 53.8% of the families. In 42.5% and 16.0% of the houses, children could access electrical sockets and wires, respectively. Fire alarms and extinguishers were not available in 90.8% and 82.1% of houses, respectively. Those who did not store medications and chemicals in safe places out of reach of children accounted for 56.7% and 63.3% of families, respectively. CONCLUSIONS: Many of the studied families are not providing an adequate safe environment for children in their houses. Therefore, actions should be taken to increase awareness about accidental injuries prevention within homes and to implement actions so that a safe home environment can be enjoyed by children.

The primary objective was to examine and draw comparisons between Omani adults and children with neurological disorders who pursued medical treatment abroad after being evaluated by local specialists. The study also aimed to gain insights into these patients' motivations and experiences. A related objective was to explore the sociocultural factors and family dynamics that shape the attitudes towards illness and treatment seeking. METHODS: In this cross-sectional study, Omani patients treated at a major tertiary hospital in Muscat for neurological disorders and subsequently traveled overseas for treatment were identified and administered a structured questionnaire. RESULTS: The participants were 116 Omani nationals (62 children and 54 adults) with neurological disorders, diagnosed predominantly with epilepsy (71.6%) followed by developmental delay, muscular dystrophy, and encephalopathy. Only 19.8% of patients received government sponsorship. The majority (69.8%) followed the recommendations of family members. Most (63.8%) participants reported positive outcomes after treatment abroad, though 4.3% developed complications and 5.2% acquired nosocomial infections. Most (83.6%) participants opined that the treatment they received overseas was comparable to what they would have received in Oman. There were no significant differences between children and adults in most of these aspects. CONCLUSIONS: Public awareness should be increased regarding the pros and cons of medical tourism. Patients must be made aware of the advanced treatment facilities available locally. Efforts should be made to enhance patient outcomes and satisfaction by adopting more efficient and patient-friendly processes.

METHODS: The subjects were patients with chronic HF, who were hospitalized for ADHF. Using ultrasound methods-lung ultrasound, ultrasound assessment of hepatic venous congestion as per the venous excess ultrasound (VExUS) protocol, and indirect elastometry-we assessed the number of B-lines, hepatic venous congestion, and liver density of the patients. Clinical outcomes were assessed using a structured telephone survey method at 1, 3, 6, and 12 months after discharge. Combined overall mortality and readmission rates associated with HF were assessed. Threshold values for different methods for detecting congestion were set as follows: the number of B-lines in ultrasound data > 5; liver density > 6.2 kPa. RESULTS: The subjects were 207 patients (54.1% male; mean age = 70.7 ± 12.8 years). A total of 63 (30.4%) endpoints and 23 (11.1%) deaths were detected within 364 days (IQR = 197-365). Liver density > 6.2 kPa had a hazard ratio (HR) of 1.9 (95% CI: 1.0-3.3; = 0.029). Hepatic venous congestion (VExUS protocol) had HR of 2.8 (95% CI: 1.3-5.7; = 0.004). There was a significant increase in the risk of overall prognostic value in the presence of congestion, identified by liver fibroelastometry + lung ultrasound (HR = 10.5, 95% CI: 2.3-46.2; p = 0.002). The ultrasound assessment of hepatic venous congestion (VExUS + lung ultrasound protocol) yielded HR of 16.7 (95% CI: 3.9-70.7; < 0.001). For all three methods combined, the overall HR was 40.1 (95% CI: 6.6-243.1; < 0.001). CONCLUSIONS: A combination of ultrasound diagnostic methods that include the number of B-lines, presence of hepatic venous congestion according to the VExUS protocol, and liver density according to indirect elastometry at discharge may have an independent prognostic value for patients with ADHF.

While published reports confirm this trend, few studies explored the factors that determine which fellowship training surgical residents would pursue. This cross-sectional study aims to investigate the factors influencing fellowship choices made by surgical trainees in Oman. METHODS: An online questionnaire, developed based on previously validated instruments, included 14 factors considered crucial for choosing a future career. Statistical analysis was performed to determine item-level validity, scale-level validity, and reliability. The survey was distributed via email and closed after six weeks for data analysis. RESULTS: The survey achieved a response rate of 60.9%. The analysis revealed that the most influential factor among surveyed surgeons in selecting a subspecialty was prestige, with an average score of 2.7. The least reported influential factors were variety of cases (average score of 1.8) and personal interest (average score of 1.4). Only 57.7% of respondents received career choice guidance. CONCLUSIONS: Factors influencing the choice of surgical subspecialties vary among the different groups. This information can be valuable in designing programs and structuring professional career guidance and counseling.

We sought to survey the views of non-neurologist and non-psychiatrist physicians in Oman on the use of CAM for epilepsy. METHODS: We used convenience sampling to recruit physicians (except neurologists and psychiatrists) from all 11 governorates of Oman. The online questionnaire was open to physicians from 5 January 2022 to 15 February 2023. This study collected anonymous data on their demographics, discipline, work settings, geographical area, and years of practice. Additionally, participants were asked to answer questions about their perception of CAM use and its effectiveness in treating epilepsy. RESULTS: A total of 190 physicians participated, of whom 69.5% were men. Respondents were mostly 36 to 45 years old (51.1%). The majority (52.1%) were general practitioners, 21.1% were internists, 17.9% were pediatricians, and 8.9% were family physicians. Most participants (n = 144; 75.8%) believed that CAM may help treat patients with epilepsy (PWE). The most common therapies that participants considered helpful were meditation (46.0%), prayers (44.7%), yoga (32.6%), and exercise (31.1%). CONCLUSIONS: While the evidence supporting the use of CAM for the treatment of epilepsy is scarce, this survey showed that most physicians (non-neurologists and non-psychiatrists), who manage PWE in Oman, believed that some CAM modalities would help treat epilepsy. Well-designed controlled trials are needed to provide reliable evidence on the usefulness of CAM options in PWE.

Cases of non-valvular, left ventricular (LV) cavity PFE are extremely rare. We report the case of a 75-year-old man with a history of exertional chest pain. He was referred to our tertiary-care hospital for evaluation. On the echocardiogram, the patient was found to have a LV lesion related to the papillary muscle. Cardiac magnetic resonance imaging revealed an enhancing mobile lesion related to the LV anterolateral papillary muscle which suggested a myxoma. The patient underwent surgical resection of the lesion, later histopathologically confirmed to be PFE.

While these grades are simple, they do not always correlate with patient outcomes. This study aimed to evaluate the status of estrogen receptor (ER), progesterone receptor (PR), and proliferation marker Ki-67/molecular immunology borstel-1 (MIB-1) in the three grades of meningioma. METHODS: We evaluated the data of meningioma patients who were seen in our tertiary center over 10 years-8.5 years retrospectively and 1.5 years prospectively. Their archival hematoxylin and eosin stained slides were reviewed and re-graded according to the World Health Organization 2021 criteria. Immunohistochemical analysis for ER, PR, and Ki-67 was performed on all grade 2 and grade 3 meningiomas and 30 cases of grade 1 formalin-fixed, paraffin-embedded samples. RESULTS: Of the 276 cases included in the study, there were 231 (83.7%) cases of grade 1 meningioma, 34 (12.3%) cases of grade 2, and 11 (4.0%) cases of grade 3. ER was positive in 26.0% of grade 1 tumors, 5.8% of grade 2, and 0.0% of grade 3. PR was positive in 70.0% of grade 1 tumors, 20.0% of grade 2, and 18.0% of grade 3. The Ki-67/MIB-1 labeling index (LI) was 2.1 in grade 1, 6.3 in grade 2, and 13.4 in grade 3 tumors. For both PR and Ki-67, the differences between grades 1, 2, and 3 tumors were significant ( < 0.001). There was a significant inverse relationship between mean Ki-67 LI and PR status, with increasing grade of tumor. CONCLUSIONS: Ki-67/MIB-1 LI has significant positive correlations with meningioma grade and its recurrence, which makes it a useful auxiliary method for the routine assessment of meningiomas, especially in patients with borderline atypia. The expression of PR, on the other hand, is a positive prognostic indicator and has a substantial correlation with histological grade. In cases of subtotal resection, high proliferative/recurrence rates, and borderline histopathology, the PR status in combination with the MIB-1 LI can offer insights into the behavior and the recurrence probability of a meningioma.

METHODS: A single-center retrospective cohort study was conducted at Sultan Qaboos University Hospital (SQUH) from October 2009 to October 2019. We included all Omani patients (pediatric and adult) treated at SQUH with the standard therapy, for whom DNA extraction was performed at diagnosis. The target mutations in both IDH1 and IDH2 genes were screened using the direct polymerase chain reaction product sequencing method. Statistical analysis was conducted using SPSS software. Survival differences were estimated using the log-rank test. Continuous variables were presented as median (IQRs), while categorical variables were presented as frequency. RESULTS: A total of 61 patients treated, for whom DNA extraction was performed at diagnosis were evaluated. The median age was 40 (range = 25.5-65.5). The prevalence of IDH1 R132, IDH2 R140, and IDH2 R172 mutations among the study group was 6.6%, 3.3%, and 1.6%, respectively. Clinicopathologic characteristics associated with IDH mutations at diagnosis included older age, lower white blood cell count, higher median platelet counts, normal karyotype AML, and cytogenetics intermediate-risk group. The overall survival (OS) in patients harboring IDH mutations was poor, with a median OS of nine months. This analysis confirms that the response rate and OS for both IDH-mutated and IDH wild-type AML patients were comparable. This will provide contemporary data to be used for comparison with the results of novel investigational (e.g., selective IDH inhibitor) strategies. CONCLUSIONS: The current study results were consistent with the other international studies of IDH mutations in AML and demonstrate the poor prognosis associated with IDH mutations. Clinicopathologic features associated with IDH mutations included older age, lower white blood cell count, higher median platelet counts, normal karyotype AML, and cytogenetics intermediate-risk group.

We describe the case of a 35-year-old male with combined ADPKD and type 1 diabetes mellitus with a strong family history of both. At the age of 32, he developed end-stage kidney disease for which he underwent preemptive simultaneous pancreatic and kidney transplant, which in turn led to multiple perioperative complications. Evaluation of familial clustering of genetic disease is critical in genetic epidemiology and precision medicine as it enables estimation of lifetime disease risk and early assessment as well as detection of the disease among one's siblings.

It is predominantly seen among young females. The cardinal clinical features include fever and cervical lymphadenopathy. Skin eruptions have also been reported. In Oman, two cases have been reported to date, in 2005 and 2020, with only one case exhibiting skin manifestations. There is a paucity of disease in our country and worldwide. In this case report, we discuss the diagnosis of Kikuchi disease in a previously healthy 17-year-old Omani female who presented with fever, cervical lymphadenopathy, and malar rash. The clinical picture in this case resembled that of systemic lupus erythematosus. Due to the rarity of Kikuchi disease, particularly in our region, it is crucial to consider it as a differential diagnosis when a patient exhibits the aforementioned symptoms to prevent misdiagnosis and inappropriate treatment, as it can easily be misdiagnosed as systemic lupus erythematosus.

It is characterized by a state of hypovolemia with features of widespread fluid third spacing and poses diagnostic and therapeutic challenges. Here, we present a challenging case of a 36-year-old woman who experienced recurrent episodes of widespread edema and hypovolemic shock symptoms suggestive of capillary leak syndrome. The resuscitative and therapeutic measures employed in managing this disease are described in this case report.

The patient presented with complaints of abdominal distension, abdominal pain, decreased appetite, and non-bilious vomiting for 20 days with a history of mass protruding per rectum. Examination revealed a distended abdomen and prolapsing bowel loops during rectal examination, resembling intussusception. Radiological findings indicated intestinal obstruction. Surgical exploration revealed Meckel's diverticulum invading the rectum, accompanied by dense inter-bowel adhesions. The patient underwent resection of Meckel's diverticulum and repair of the rectal rent. This case highlights the rarity of Meckel's diverticulum fistulating into the rectum.

Dyshemoglobin disorders can be asymptomatic or symptomatic. We narrate the case of a 12-year-old girl who presented with a fever, cough, and oxygen saturation of 85%. She was diagnosed with COVID-19, along with a large atrial septal defect and pulmonary arterial hypertension. Arterial blood gas analysis revealed normal partial pressure of oxygen and on 100% exposure to oxygen, blood color turned chocolate brown. After the resolution of COVID-19 in 10 days, the patient was treated with oral ascorbic acid and successful atrial septal defect repair. It is important to suspect dyshemoglobin disorder in a patient who presents with hypoxia/hypoxemia.

METHODS: This retrospective cohort study included 60 patients diagnosed with PAH at a high-volume tertiary care center, treated with intravenous or subcutaneous prostanoids. Data were collected from 2015 to 2019, including echocardiographic assessments, right heart catheterization, World Health Organization functional class evaluations, six-minute walk distance tests, and biomarkers such as brain natriuretic peptide and N-terminal prohormone of brain natriuretic peptide. Follow-up was conducted at least 90 days post-treatment initiation. RESULTS: Pericardial effusion was observed in 31.7% of patients before therapy. Patients with moderate to large effusions had a significantly higher mortality risk (HR = 1.92; 95% CI 1.1-44.78; 0.0044), while small effusions appeared protective (HR = 0.27; 95% CI 0.15-0.48; 0.006). Survival rates declined from 89% at one year to 71% at three years post-therapy, with effusion presence correlating with more severe PAH manifestations. CONCLUSIONS: Initial pericardial effusion severity is a critical predictor of mortality in PAH patients. Early assessment and stratified management of pericardial effusion are essential for optimizing therapeutic outcomes in PAH management. Future research should explore targeted interventions for managing pericardial effusion to improve patient prognosis.

METHODS: The researchers approached patients who had been diagnosed with schizophrenia at Al-Amal Hospital for Psychiatric Diseases, Sana'a. Controls were drawn randomly from the general population. The HLA class II alleles of the participants were examined. The genotypes of the HLA-DQB1 and HLA-DRB1 alleles were determined by polymerase chain reaction using sequence-specific primers. RESULTS: The subjects comprised 110 patients with schizophrenia, matched by an equal number of controls. The prevalence of HLA-DRB1*04 was significantly higher among patients than among controls (7.3% vs. 0.0%; 0.003), as was HLA-DRB1*07 (62.7% vs. 17.3%, odds ratio (OR) = 8.1, 95% CI: 4.3-15.1; < 0.001). HLA-DRBI*14 was significantly less prevalent among patients (0.9% vs. 11.8%, OR = 0.06, 95% CI: 0.01-0.50, χ = 10.9; < 0.001). HLA-DQB1*07 was the most common allele discovered in schizophrenia patients and was found to have a much higher incidence in patients than the control group (22.7% vs. 4.5%, OR = 6.2, 95%CI: 2.3-16.8, χ = 15.4; < 0.001). CONCLUSIONS: The HLA-DQB1 and HLA-DRB1 gene loci are linked to schizophrenia in the Yemeni population, according to the current study's evidence.
