A Novel Cyclin-Dependent Kinase 13 Variant and Unusual Association of Situs Inversus Partialis in a Child From Bahrain: A Case Report and Literature Review.

Cyclin-dependent kinase 13 (CDK13)-related disorder is a rare autosomal dominant disease caused by pathogenic variants in the CDK13 gene. This disorder was found to be related to several clinical features, including structural cardiac anomalies, developmental delay, anomalies of the corpus callosum, and a variety of facial dysmorphisms. In addition, feeding difficulties and neonatal hypotonia might also present. The diagnosis of this disorder is based on molecular genetic testing to detect the causative pathogenic variants. Here, we report a case of a one-year-old girl from Yemen, residing in Bahrain, with a CDK13-related disorder who was found to have an unusual association of abdominal situs inversus along with multiple structural cardiac anomalies, including atrial septal defect, ventricular septal defect, patent ductus arteriosus, interrupted inferior vena cava, bilateral superior vena cava, mild coarctation of the aorta, dilated coronary sinuses, and mild regurgitation in the tricuspid valve. Moreover, facial dysmorphism including medial epicanthal folds, posteriorly rotated ears, and a depressed nasal bridge was also noted. Further assessment showed a delay in reaching developmental milestones, including speech and motor delay. The patient also presented with recurrent episodes of upper respiratory tract infections, acute bronchiolitis, and lobar pneumonia which required admission to the intensive care unit and ventilation. The last infection episode was at the age of one year. Thereafter, the patient underwent cardiac repair of the ventricular septal defect followed by no more infection episodes until the age of one year and two months. The diagnosis of CDK13 was confirmed by a whole exome sequencing test which demonstrated a novel missense variant in exon 14 of the CDK13 gene as a variant of uncertain significance in a heterozygous state.

Assessment of Patient Safety Culture Among Nurses Working at Tertiary Care Hospitals in Aljouf Region, Saudi Arabia.

INTRODUCTION: Patient safety is a fundamental element in healthcare quality and a major challenge in achieving universal health coverage, especially in low- and middle-income countries. The first step to improve patient safety is to evaluate the safety culture in hospitals. This study aimed to investigate the patient safety culture among nurses and determine the factors affecting it. METHODS: This cross-sectional study was conducted among 423 nurses working at tertiary care hospitals in the Al-Jouf region in Saudi Arabia. RESULTS: The highest score for patient safety among nurses was for teamwork within units (16.41 ± 2.44). The lowest score was for nonpunitive response to errors (5.87 ± 1.92). In addition, 83% of the participants did not report any events in the past 12 months. More perception of patient safety was significantly higher among females than males in dimensions of teamwork within units, frequency of events reported, and staffing. Furthermore, teamwork within units, management support for patient safety, staffing, non-punitive response to errors, and handoffs and transitions were significantly higher among participants in direct contact with patients. The Hospital Survey on Patient Safety Culture (HSOPSC) scale is significantly higher among non-Saudi nurses, nurses with bachelor's education, nurses with less working hours per week, and those who had training on patient safety. CONCLUSION: The current study showed that the majority of the participants did not report any events in the past 12 months. The highest score for patient safety culture dimensions among nurses was for teamwork within units while the lowest score was for nonpunitive response to errors.

Laser Ablation of Pilonidal Sinus in a Patient With Hemophilia Type A: A Case Report and Review of the Literature.

Pilonidal sinus (PNS) is a common occurrence in young men. It is often caused by blockage of the sebaceous glands in the hair follicles in the sacrococcygeal area. Hemophilia type A is a hemorrhagic disorder caused by a deficiency of factor VIII. It presents with excessive bleeding, either spontaneously or secondary to trauma. The mainstay of treatment for PNS is often excision of the sinus; however, recently, laser ablation has started to be commonly used. In this article, we present a case of a young man with hemophilia A presenting with recurrent PNS successfully managed with laser ablation with no complications.

Satisfaction and Quality of Life in Patients Who Underwent Post Massive Weight Loss Body Contouring Procedures: A Tertiary Center Experience in Bahrain.

Background: Incidence of body contouring surgeries (BCS) rose significantly to overcome problems resulted from post-Bariatric Surgery (BS). We aimed to evaluate satisfaction level and quality of life (QOL) in patients' post-BCS. Methods: In this retrospective prospective study, patients who underwent BCS in Plastic Surgery Department, Salmaniya Medical Complex, Bahrain, in 2017-2018, were enrolled. Demographic and anthropometric data were collected. BS-group's QOL and satisfaction level were assessed using a questionnaire. Results: Of 929 plastic surgery admissions, 316 (34%) were for BCS (249 patients). Fifty-eight (28%) patients underwent 82 BS were recruited, mostly females (n=42, 72.4%). The mean age was 37.4±9.6 years. Excess abdominal skin was the most area of concern (n=50, 86.2%). Median pre-BCS body mass index was 26.9 (interquartile range: 25.6-29.8) kg/m2. Most patients were overweight (n=26, 44.8%). Abdominoplasty was the commonest BCS (n=172, 50.6%). This was also the case in 82 BCS in post-BS group (n=38, 46.3%). In post-BS group, post-operative complications were noted in 25/82 (30.5%) patients with wound problems being the most frequent (n=14, 17.1%). Most patients rated their experience as better in all questionnaire domains and most (n=45, 54.9%) rated their satisfaction level as excellent. Older age gave better overall satisfaction (P<0.001) while employed patients had better overall QOL (P=0.012) and self-confidence (P=0.048). Females had better satisfaction with body appearance (P<0.001) while those underwent abdominoplasty or breast surgeries had lower physical activity (P=0.042). Conclusion: This study showed improvement in patient's QOL post-BCS with excellent overall satisfaction, findings that could be affected by age, sex, and occupation.

Safety of COVID-19 Vaccine in Patients with Rheumatic and Musculoskeletal Diseases.

Objectives: The main purpose of this study was to determine the frequency of COVID-19 vaccine side effects in patients with rheumatic diseases and to examine any potential associations with medications, disease type, or comorbidities. Methods: A multicentre cross-sectional study from rheumatology units in different hospitals in Iraq was carried out between 8th of August 2021 and 4th of August 2022. Patients were eligible for inclusion if they have a rheumatic disease and have taken one or more doses of any COVID-19 vaccine. Results: A total of 661 (57.8% female, mean age 46.51± 12.97 years) patients with rheumatic illnesses who received the "COVID-19" vaccination were included in this study. Rheumatoid arthritis was the most frequent diagnostic group. The Pfizer vaccine was given to the majority of patients (74.6%), followed by Sinopharm (16.2%), and AstraZeneca (9.2%). Side effects were detected in 661(100%) and 528 (100%) patients following the first and second vaccination doses, respectively; among which the most frequent were injection site pain in 57.8% following the first dose and 47.6% after the second dose, followed by fatigue and fever. According to multivariate logistic regression models, age (B=-0.204, p = 0.000), had a significantly inverse correlation coefficient with the experience of greater side effects. Rheumatic disease flares reported in 9.9%, 10.3%, and 8.2% of patients who received the Pfizer, Sinopharm, and AstraZeneca vaccines, respectively. Conclusion: The "COVID-19" vaccination has a reassuring safety profile with no greater risk of adverse events in any specific illness or pharmacological therapy.

Oral administration of proniosomal glibenclamide formulation protects testicular tissue from hyperglycemia fluctuations and ROS via Nrf2/HO-1 pathway.

Type 2 diabetes causes high blood sugar due to insulin malfunction and is linked to male infertility. Using proniosomes can enhance the effectiveness of Glibenclamide, a medication that stimulates insulin secretion. In our study, male rats with diabetes were treated with GLB with or without proniosomal for 14 days. Proniosomal formulations maintained glucose levels prevented weight loss and showed normal testicular tissue. GLB-proniosomal reduces ROS caused by T2DM through Nrf2, HO-1 pathway and increases CAT, SOD, and GSH production in response to insulin and glucose uptake. The reference and proniosomal treatments showed CAT and SOD significant enzymatic elevation compared to the positive and negative control. CAT significantly correlated with Gpx4 expression with P = 0.0169 and r = 0.98; similarly, the enzymatic activity of SOD also showed a positive correlation between the average glucose levels (r = 0.99 and P = 0.0037). Intestinally, GSH analysis revealed that only proniosomal-GLB samples are significantly elevated from the positive control, with a P value of 0.0210. The data showed proniosomal-GLB was more effective than pure GLB, confirmed by higher Nrf2 (2.050 folds), HO-1 (2.148 folds), and GPx4 (1.9 folds) transcript levels relative to the control with less sample diversity compared to the reference samples, indicating proniosomal stabilized GLB in the blood. Administering GLB and proniosomes formulation has effectively restored testicular function and sperm production in diabetic rats by regulating ROS levels and upregulating anti-ROS in response to glucose uptake. These findings may lead to better treatments for diabetic patients who have infertility issues.

Pediatric and adult liver transplantation in Bahrain: The experiences in a country with no available liver transplant facilities.

BACKGROUND: Liver transplantation (LT) is a life-saving procedure for patients with end-stage liver disease and has become the standard and most effective treatment method for these patients. There are many indications for LT that vary between countries and settings. The outcome of LT depends on the available facilities and surgical expertise, as well as the types of liver graft donors available. AIM: To assess the clinical characteristics of patients from Bahrain who underwent LT overseas, and analyze factors affecting their survival. METHODS: In this retrospective cohort study, we reviewed the medical records and overseas committee registry information of all pediatric and adult patients who were sent overseas to undergo LT by the Pediatric and Medical Departments of Salmaniya Medical Complex and Bahrain Defence Force Hospital via the Overseas Treatment Office, Ministry of Health, Kingdom of Bahrain, between 1997 and 2023. Demo graphic data, LT indication, donor-recipient relationship, overseas LT center, graft type, post-LT medications, and LT complications, were collected. Outcomes measured included the overall and 5-year LT survival rate. Fisher's exact, Pearson χ2, and Mann-Whitney U tests were used to compare the pediatric and the adults' group in terms of clinical characteristics, donor-recipient relationship, medication, complications, and outcome. Survival analysis was estimated via the Kaplan-Meier's method. Univariate and multivariate analyses were used to detect predictors of survival. RESULTS: Of the 208 eligible patients, 170 (81.7%) were sent overseas to undergo LT while 38 (18.3%) remained on the waiting list. Of the 170 patients, 167 (80.3%) underwent LT and were included in the study. The majority of the patients were Bahraini (91.0%), and most were males (57.5%). One-hundred-and-twenty (71.8%) were adults and 47 (28.3%) were children. The median age at transplant was 50.0 [interquartile range (IQR): 14.9-58.4] years. The main indication for pediatric LT was biliary atresia (31.9%), while that of adult LT was hepatitis C-related cirrhosis (35.0%). Six (3.6%) patients required re-transplantation. Most patients received a living-related liver graft (82%). Pediatric patients received more living and related grafts than adults (P = 0.038 and P = 0.041, respectively), while adult patients received more cadaveric and unrelated grafts. Most patients required long-term immunosuppressive therapy after LT (94.7%), of which tacrolimus was the most prescribed (84.0%), followed by prednisolone (50.7%), which was prescribed more frequently for pediatric patients (P = 0.001). Most patients developed complications (62.4%) with infectious episodes being the most common (38.9%), followed by biliary stricture (19.5%). Tonsilitis and sepsis (n = 12, 8.1% for each) were the most frequent infections. Pediatric patients experienced higher rates of infection, rejection, and early poor graft function than adult patients (P < 0.001, P = 0.003, and P = 0.025, respectively). The median follow-up time was 6.5 (IQR: 2.6-10.6) years. The overall survival rate was 84.4%, the 5-year survival rate, 86.2%, and the mortality rate, 15.6%. Younger patients had significantly better odds of survival (P = 0.019) and patients who survived had significantly longer follow-up periods (P < 0.001). CONCLUSION: Patients with end-stage liver disease in Bahrain shared characteristics with those from other countries. Since LT facilities are not available, an overseas LT has offered them great hope.

Distinct CD16a features on human NK cells observed by flow cytometry correlate with increased ADCC.

Natural killer (NK) cells destroy tissue that have been opsonized with antibodies. Strategies to generate or identify cells with increased potency are expected to enhance NK cell-based immunotherapies. We previously generated NK cells with increased antibody-dependent cell mediated cytotoxicity (ADCC) following treatment with kifunensine, an inhibitor targeting mannosidases early in the N-glycan processing pathway. Kifunensine treatment also increased the antibody-binding affinity of Fc γ receptor IIIa/CD16a. Here we demonstrate that inhibiting NK cell N-glycan processing increased ADCC. We reduced N-glycan processing with the CRIPSR-CAS9 knockdown of MGAT1, another early-stage N-glycan processing enzyme, and showed that these cells likewise increased antibody binding affinity and ADCC. These experiments led to the observation that NK cells with diminished N-glycan processing capability also revealed a clear phenotype in flow cytometry experiments using the B73.1 and 3G8 antibodies binding two distinct CD16a epitopes. We evaluated this "affinity profiling" approach using primary NK cells and identified a distinct shift and differentiated populations by flow cytometry that correlated with increased ADCC.

Evaluation of effect on stability of implants with and without platelet rich fibrin using a resonance frequency analyzer - An in-vivo study.

Background: Although the conventional replacement for lost teeth has been partial or full dentures, the need for a fixed, esthetic, and functional restoration makes dental implants a reliable alternative. Aim: To evaluate the initial and final stability of platelet rich fibrin coated implants using resonance frequency analyzer. Method: ology: Thirteen patients with two or more missing teeth were informed about the procedure, and a consent form was obtained after cone beam computer tomography evaluation. Blood was drawn from the anticubital area of the patient, which was centrifuged to obtain platelet-rich fibrin. In all, 26 implants were placed, among which 13 were platelet-rich fibrin-coated (test group) and 13 were without platelet-rich fibrin (control group), and implant stability quotient values were recorded. Results: The mean age of the patients was 34.4 (SD = 4.28). Majority of the patients were males (9; 69.2%) whereas there were only four (30.8%) female patients. When comparison between overall primary implant stability with and without PRF was done, the mean difference was 5.12 and this difference was not statistically significant (p = 0.221) whereas a statistically significant difference (p = 0.019) was found when comparison between overall secondary implant stability was done with and without PRF. The primary and secondary stability values for the control group were 69.18 ± 7.45 and 73.84 ± 8.21 respectively, and the primary and secondary stability values for the test group were 64.06 ± 12.66 and 81.49 ± 7.61 respectively, which showed statistically significant differences among the groups. The difference in these values signify that primary stability is more in control group whereas secondary stability is more in case group. This signifies that PRF enhances the stability of implant. Conclusion: Implants coated with platelet-rich fibrin exhibited better osseointegration than implants without platelet-rich fibrin.

Profile of paediatric occupational therapy practice in Eastern Mediterranean countries.

BACKGROUND: Paediatric occupational therapy (OT) is considered the largest practice area in OT in several regions, including the Eastern Mediterranean (EM) countries. AIMS/OBJECTIVES: This study aimed to establish a profile of paediatric occupational therapists in EM countries to identify theoretical models, assessments and interventions employed. It also investigated the therapists' usage of evidence-based practice in their practice. MATERIAL AND METHODS: We conducted a cross-sectional survey using a questionnaire which was distributed electronically to occupational therapists working with children. RESULTS: The participants included 118 therapists. Majority of the participants were working at rehabilitation centres. The primary client groups were pre- and school-age children with autism spectrum disorder and cerebral palsy. The most frequently used assessments were sensory-related tools. Activities of daily living and play were the most often targeted interventional area. Participants highlighted some of the challenges faced in implementing evidence in their practice. CONCLUSION: Paediatric occupational therapists are usually exposed to specific age groups and conditions. However, a lack of knowledge practice in some areas and challenges in others exist. SIGNIFICANCE: Within the EM region, knowledge regarding therapists' practices is lacking. Actions should be taken to improve current practice and meet the current needs of clients, and utilise evidence-based practices.

Johanson-Blizzard Syndrome: A Case Report From Bahrain With a Literature Review.

Johanson-Blizzard syndrome (JBS) is a rare hereditary autosomal recessive disorder caused by a mutation in the ubiquitin protein ligase E3 component n-recognin 1 (UBR1) gene. This syndrome is characterized by the following typical clinical features: hypoplasia or aplasia of the alae nasi, congenital scalp defects, sensorineural hearing loss, hypothyroidism, growth retardation, psychomotor retardation, imperforate anus, genitourinary anomalies, and atypical hair patterns. Here, we describe a case of a 12-year-old girl with JBS of consanguineous parents. During the last trimester of pregnancy, a congenital abnormality affecting the nose was detected. Immediately after birth, the clinical examination revealed dysmorphic features in the form of hypoplastic alae nasi, microcephaly, mild hypotelorism, and cutis aplasia on the scalp. The genetic testing of the patient showed a novel sequence change mutation of the UBR1 gene (1bp duplication causing a frameshift), while both parents were carriers for this mutation. Moreover, a diagnosis of pancreatic insufficiency and subclinical hypothyroidism was made based on clinical presentation and laboratory results. The patient was started on pancreatic enzyme replacement therapy and fat-soluble vitamins, minerals, and antioxidant syrup. Further assessment revealed hypotonia, growth impairment, delay in reaching developmental milestones, and bilateral profound sensorineural hearing loss, which was managed with bilateral cochlear implantation. In addition, the patient underwent multiple craniofacial reconstructive surgeries. This case report highlights the importance of early diagnosis and multidisciplinary care of patients with JBS.

A novel optimized eco-friendly simple spectrofluorimetric method for the determination of total catechins in green tea extract: Application to commercial tablet.

Green tea extract (GTE) contains antioxidants that are present in green tea. The active constituents of green tea extract are catechins. This study demonstrates a spectrofluorimetric method for measuring GTE's catechin concentration based on its native fluorescence. To design a quick, sensitive, and ecological spectrofluorimetric approach, all features were investigated and adjusted. This method relies on determining the GTE ethanolic solution's native fluorescence at 312 nm after excitation at 227 nm. The calibration graph displayed a linear regression for values between 0.05 and 1.0 µg mL-1. The detection and quantification limits of the proposed technique were 0.008 and 0.026 µg mL-1, respectively. Two pure catechins present in GTE, (-)-epicatechin and (-)-epigallocatechin gallate, were examined by the proposed method. The analytical estimation of GTE in the pharmaceutical tablet was achieved effectively using this approach. An adequate degree of agreement was found when the findings were compared to those obtained by the comparative technique. Therefore, the novel strategy may be used in the GTE quality control study with minimal risks to people or the environment. The quantum yields of catechins were estimated. The validated technique was accepted by the International Council of Harmonization criteria.

Determination of dose- and time-dependent hepatotoxicity and apoptosis of Lanthanum oxide nanoparticles in female Swiss albino mice.

Nanosized lanthanum oxide particles (La2O3) are commonly utilized in various industries. The potential health risks associated with La2O3 nanoparticles, cytotoxic effects at varying doses and time intervals, and the mechanisms behind their induction of behavioral changes remain uncertain and necessitate further investigation. Therefore, this study examined in vivo hepatotoxicity, considering the quantity (60, 150, and 300 mg/kg) and time-dependent induction of reactive oxygen species (ROS) over one week or 21 days. The mice received intraperitoneal injections of three different concentrations in Milli-Q water. Throughout the experiments, no physical changes or weight loss were observed among the groups. However, after 21 days, only the highest concentration showed signs of anxiety in the activity cage (p < 0.05). Subsequently, all animals treated with La2O3 NPs exhibited a significant loss of learning and memory recall using the Active Avoidances test, after 21 days (p < 0.001). Markers for anti-reactive oxygen species (ROS) such as superoxide dismutase (SOD) were significantly upregulated in response to all concentrations of NPs after seven days compared to the control group. This was confirmed by a significant increase in glutathione peroxidase (Gpx1) and pro-apoptotic Caspase-3 expression at the lowest and highest doses. Additionally, both transcription and protein levels of the anti-apoptotic BCL-2 surpassed P53 protein in a dosage-dependent manner, indicating activation of the primary anti-apoptosis pathway. After 21 days, P53 levels exceeded BCL-2 protein levels, confirming a significant loss of BCL-2 mRNA, particularly at the 300 mg/kg concentration. Furthermore, a higher transcription level of Caspase-3, SOD, and Gpx1 was observed, with the highest values detected at the 300 mg/kg concentration, indicating the activation of cell death. Histopathological analysis of the liver illustrated apoptotic bodies resulting from La2O3 NP concentration. The investigation revealed multiple inflammatory foci, cytoplasmic degeneration, steatosis, and DNA fragmentation consistent with increased damage over time due to higher concentrations. Blood samples were also analyzed to determine liver enzymatic changes, including alkaline phosphatase (ALP), alanine transaminase (ALT), aspartate aminotransferase (AST), and lipid profiles. The results showed significant differences among all La2O3 NP concentrations, with the most pronounced damage observed at the 300 mg/kg dose even after 21 days. Based on an animal model, this study suggests that La2O3 hepatotoxicity is likely caused by the size and shape of nanoparticles (NPs), following a dose and time-dependent mechanism that induces the production of reactive oxygen species and behavioral changes such as anxiety and memory loss.

Occipital Lobe Cavernoma Presenting With Headaches and Visual Hallucinations: A Case Report.

Cavernomas, also known as cavernous angiomas or cavernous malformations, are rare vascular lesions characterized by abnormal clusters of dilated capillaries without intervening brain tissue. While often asymptomatic, they can manifest with neurological symptoms such as headaches, seizures, and focal deficits. We present a case of a 45-year-old male who presented with persistent headaches and visual hallucinations. Thorough clinical assessment revealed intermittent throbbing headaches localized to the left occipital region, accompanied by brief episodes of vivid visual hallucinations. Extensive work-up, including laboratory tests and neuroimaging, identified a subependymal cavernoma in the left occipital lobe. A surgical excision was performed, resulting in sustained relief from headaches and the absence of visual hallucinations during follow-up examinations. This case contributes to the understanding of cavernomas by detailing the clinical presentation, diagnostic process, and successful surgical intervention for a subependymal cavernoma in the left occipital lobe. The resolution of symptoms postoperatively underscores the importance of individualized treatment approaches, considering factors such as lesion location, patient age, and associated risks. The case highlights the evolving knowledge in cavernoma management and emphasizes the need for tailored therapeutic decisions in addressing neurovascular disorders.

Gestational diabetes augments group B Streptococcus infection by disrupting maternal immunity and the vaginal microbiota.

Group B Streptococcus (GBS) is a pervasive perinatal pathogen, yet factors driving GBS dissemination in utero are poorly defined. Gestational diabetes mellitus (GDM), a complication marked by dysregulated immunity and maternal microbial dysbiosis, increases risk for GBS perinatal disease. Using a murine GDM model of GBS colonization and perinatal transmission, we find that GDM mice display greater GBS in utero dissemination and subsequently worse neonatal outcomes. Dual-RNA sequencing reveals differential GBS adaptation to the GDM reproductive tract, including a putative glycosyltransferase (yfhO), and altered host responses. GDM immune disruptions include reduced uterine natural killer cell activation, impaired recruitment to placentae, and altered maternofetal cytokines. Lastly, we observe distinct vaginal microbial taxa associated with GDM status and GBS invasive disease status. Here, we show a model of GBS dissemination in GDM hosts that recapitulates several clinical aspects and identifies multiple host and bacterial drivers of GBS perinatal disease.

Diagnostic Accuracy of Cerebrospinal Fluid Multiplex Polymerase Chain Reaction Panel Testing in Patients With Suspected Central Nervous System Infections: A Multi-Center Study in the United Arab Emirates.

Background Delays in diagnosis and treatment of central nervous system (CNS) infections can lead to significant morbidity and mortality among children and adults. Prior antibiotic treatment is a major hurdle to accurate diagnosis due to falsely negative cerebrospinal fluid (CSF) cultures in partially treated patients. Increasingly, molecular diagnostic methods using multiplex polymerase chain reaction (mPCR) testing on CSF samples are being utilized in clinical practice for timely and accurate diagnosis. However, there is no data regarding the diagnostic accuracy or clinical impact of CSF mPCR testing in the Middle East region. We sought to compare the diagnostic accuracy of an automated mPCR CSF panel with routine CSF culture, the current gold standard, in the United Arab Emirates (UAE).  Methods This single-gated, multi-center, diagnostic accuracy study included patients from birth onwards who were admitted to any of the three participating hospitals with an initial diagnosis of meningitis or encephalitis, between January 2017 and March 2021, and had CSF samples collected for mPCR and culture. Sociodemographic, clinical, and molecular data were collected for all. Results A total of 353 CSF samples were collected from patients from 0-90 years old hospitalized for suspected CNS infection. Children constituted 51% of the study population, and males were slightly over-represented (55.2%). Pathogens were detected by mPCR in 78 (22%) CSF samples, of which 19 (24%) were bacteria and 59 (76%) were viruses. No fungal pathogens were detected. Enteroviruses were the most prevalent CNS pathogen among our cohort (40%), followed by herpes simplex virus type 2 (HSV-2) (12.5%). Children constituted 69% of positive samples for enterovirus, while HSV-2 was exclusively detected among adults. Using CSF culture as the diagnostic gold standard, the mPCR panel demonstrated high specificity (100%) and sensitivity (96.3%) in diagnosing CNS infection among all age groups. mPCR testing demonstrated a high overall percentage of agreement (OPA) with CSF culture (98.9%). Patients with bacterial meningitis had a significantly longer hospitalization (p=0.004) and duration of antibiotic therapy (p=0.001) compared to those with viral meningitis. Three CSF samples were negative on mPCR testing but positive on culture. These pathogens included: methicillin-sensitive Staphylococcus aureus(MSSA), Bacillus cereus, and Mycobacterium Tuberculosis (MTB). In addition, 13 patients had negative CSF cultures but tested positive on CSF mPCR. These pathogens included Streptococcus pneumoniae (seven patients), Haemophilus influenzae (three patients), Streptococcus agalactiae (two patients), and Escherichia coli (one patient). All discordant results were confirmed by reviewing the patient's clinical presentation, CSF analysis, clinical course, and final diagnosis. Conclusion CSF mPCR panel is a highly sensitive and specific diagnostic tool for the diagnosis of CNS infections among all age groups in the UAE. Routine use of CSF mPCR panels can decrease healthcare costs by reducing the length of stay and can also aid antibiotic stewardship efforts by reducing antibiotic overuse in patients with viral CSF infections. CSF culture and mPCR complement each other by identifying CNS pathogens in patients with prior antibiotic exposure who would otherwise be missed if relying on CSF culture alone. However, concomitant CSF culture samples should be sent to avoid missing unusual CNS pathogens.

Pregnancy-Induced Thrombotic Microangiopathy in Systematic Lupus Erythematosus: A Case Report.

Thrombotic microangiopathy (TMA) is a severe systemic disorder with multiorgan manifestations due to thrombosis of the microvasculature. Pregnancy and post-partum are particularly high-risk periods for many forms of TMA. The disease progression is rapid and can lead to organ failure and even death; therefore, urgent recognition and treatment are paramount. The presence of other triggers such as infections or autoimmune diseases like systematic lupus erythematosus (SLE) can add further complexity, which emphasizes the need for definitive diagnostic investigations such as kidney biopsy to promptly direct further diagnosis and management. We describe a case of a 27-year-old female with post-partum severe acute kidney injury and nephrotic range proteinuria. She had a new diagnosis of active SLE and was found to have TMA on kidney biopsy without conclusive features of lupus nephritis. She was managed successfully with plasma exchange with rapid improvement of her kidney markers.
