Role of antenatal care in reducing the risk of postpartum acute kidney injury.

Objective: Antenatal visits play a very important role to diagnose and manage pregnancy related health issues. This study was an attempt to identify the reasons that increase the risk of postpartum acute kidney Injury with special focus on antenatal care. Methods: We analyzed 110 patients in Nephrology and Gynaecology wards in Lahore General Hospital. Out of these 40 had Postpartum Acute Kidney Injury and 70 patients did not have it. Questionnaire regarding aspects of antenatal care (demographics, timing and number of antenatal visits) was filled by the patient or immediate family members. Results: Mean age of the 110 patients was 26.45 years. Mean Duration of pregnancy in the control group was 36.12 weeks and in cases it was 31.62 weeks. Out of 110 patients, 36(32.72%) patients did not have any antenatal visit while 62(56.3%) patients had more than five visits. Out of the 40 Postpartum Acute Kidney Injury patients, 23(57.5%) patients did not get any antenatal care. Out of 70 patients without Postpartum Acute Kidney Injury, 13 did not have any antenatal care. There were 19 patients who did not have booked visits because of financial Issues, followed by lack of awareness in 12 patients, distance issues for three patients and lack of family support for two patients. Conclusion: Patients who did not have antenatal care were at an increased risk of developing PPAKI. Financial issues and lack of awareness were the most common risk factors for compromised antenatal care.

Systematic Review of the Clinical Characteristics and Management of Isaac Syndrome.

OBJECTIVES: Isaac syndrome (IS) is a condition characterized by peripheral nerve hyperexcitability caused by voltage-gated potassium channel (VGKC)-complex antibodies. Muscle twitching, stiffness, hypertrophy, and dysautonomic characteristics, such as hyperhidrosis, are common manifestations. The syndrome can be autoimmune or paraneoplastic, with thymoma being a common cause of paraneoplastic IS. Furthermore, this condition could be handed down from one generation to another. However, there is limited information regarding outcomes, relapses, associated syndromes, associated malignancies (other than thymoma), and treatment options. Despite its rarity, there remains a need for effective management strategies for patients with IS. To address this gap, we conducted a systematic review to summarize the most common and effective treatments of IS in immunomodulatory agents and symptomatic medications, as well as to describe outcomes, relapses, and associated malignancies. Altogether, this review serves to guide clinical practice recommendations for IS and highlight areas for further research. METHODS: We used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol to conduct a systematic review of cases reposted through the PubMed and Google Scholar databases. The terms "Isaac Syndrome" and "Acquired Neuromyotonia" were used. The Joanna Briggs Institute's critical appraisal tool was used to evaluate the quality of the included studies. RESULTS: We identified 61 case reports and 4 case series, comprising a total of 70 patients with IS (mean age at onset: 42.5 ± 18 years, and 69% were males). Fourteen cases reported relapses. Thymoma was the most common malignancy associated with IS, followed by lymphoma. Among various serum antibodies, voltage-gated potassium channel-complex antibodies were the most reported antibodies elevated in IS (reported in 38 patients and elevated in 21 patients [55.2%]), followed by acetylcholine ganglionic receptor antibodies, which were reported in 30% of patients (n = 21) and were elevated in 5 cases. The most common electromyography findings were myokymic discharges (n = 22), followed by fasciculations (n = 21) and neuromyotonia (n = 19). For treatment, combining anticonvulsants such as carbamazepine with immunotherapy therapy showed the best results in controlling the symptoms. Among immunotherapy therapies, the combination of plasma exchange plus intravenous high-dose steroids achieved the best results in the acute treatment of IS ([n = 6], with improvement noted in 83.3% [n = 5] of cases). Among the symptomatic treatments with anticonvulsants, carbamazepine was the most efficacious anticonvulsant in treatment of IS, with an average effective dosing of 480 mg/day (carbamazepine was used in 32.3% of acute treatment strategies [n = 23], with improvement noted in 73.9% [n = 17] of cases). CONCLUSIONS: IS a rare neuromuscular syndrome that tends to affect middle-aged men. These patients should be screened for thymoma and other malignancies such as lymphomas. The management of IS symptoms can be challenging, but based on our review, the combination of multiple immunosuppressives such as IV steroids and plasmapheresis with anticonvulsants such as carbamazepine seems to achieve the best results.

Contemporary innovations in two-dimensional transition metal dichalcogenide-based P-N junctions for optoelectronics.

Two-dimensional transition metal dichalcogenides (2D-TMDCs) with various physical characteristics have attracted significant interest from the scientific and industrial worlds in the years following Moore's law. The p-n junction is one of the earliest electrical components to be utilized in electronics and optoelectronics, and modern research on 2D materials has renewed interest in it. In this regard, device preparation and application have evolved substantially in this decade. 2D TMDCs provide unprecedented flexibility in the construction of innovative p-n junction device designs, which is not achievable with traditional bulk semiconductors. It has been investigated using 2D TMDCs for various junctions, including homojunctions, heterojunctions, P-I-N junctions, and broken gap junctions. To achieve high-performance p-n junctions, several issues still need to be resolved, such as developing 2D TMDCs of superior quality, raising the rectification ratio and quantum efficiency, and successfully separating the photogenerated electron-hole pairs, among other things. This review comprehensively details the various 2D-based p-n junction geometries investigated with an emphasis on 2D junctions. We investigated the 2D p-n junctions utilized in current rectifiers and photodetectors. To make a comparison of various devices easier, important optoelectronic and electronic features are presented. We thoroughly assessed the review's prospects and challenges for this emerging field of study. This study will serve as a roadmap for more real-world photodetection technology applications.

Lance-Adams Syndrome: Case series and literature review.

Background: Lance-Adams Syndrome (LAS) is a rare complication of successful cardiopulmonary resuscitation (CPR). It is a form of posthypoxic myoclonus characterized by action or intention myoclonus developing days to months after an hypoxic insult to the brain. LAS, especially early in a patient's clinical course, can be challenging to diagnose. Electroencephalogram (EEG) pattern of midline spike-wave discharge associated with favorable prognosis. There is no consensus in treatment of LAS but use of various anti-epileptic medications has been documented in literature. Case Presentation: In this case series, all of the patients presented after achieving return of spontaneous circulation (ROSC) and subsequently developed myoclonus. EEG findings beyond the initial hospitalization continued to show later showed changes consistent with LAS in three of the four patients. Different combinations of AEDs were used in the management of LAS with variable success and adverse effects. Conclusion: Our cases highlight that the characteristic EEG pattern can be useful in the diagnosis of LAS and allow for better prognostication and management in patients with posthypoxic myoclonus. We reviewed the available literature to better understand the prevalence, mechanism, clinical presentation, diagnosis, and management of LAS.

Psychosocial Factors Affecting Drug Relapse among Youth in Punjab, Pakistan.

The present study was intended to examine the effect of psychosocial factors on the stigma of mental illness among people addicted to drugs who have relapsed in Punjab, Pakistan. A sample composed of 116 people addicted to drugs and who have relapsed was collected through the purposive sampling technique. Certain self-report measures were used to assess the pertinent study variables. The results elucidated that self-efficacy, social support, and conscientiousness were found to be negative predictors and neuroticism a positive predictor of stigma. The results also confirmed social support as being a significant moderator in the relationship between self-efficacy and stigma, and self-efficacy as being a significant moderator in the relationship between social support and stigma. It was safe to conclude that psychosocial factors such as self-efficacy, social support, personality traits and stigma have a significant role in causing addiction relapse. The conclusions made have been discussed thoroughly.

Risk factors associated with prolonged intensive care unit stay in post coronary artery bypass grafting patients with chronic kidney disease.

Objective: Prolonged intensive care unit stay not only increases hospital cost but it also prevents hospital equipment to be used by other patients who need them. The aim of this study was to identify factors that affect the duration of intensive care unit stay in post coronary artery bypass grafting patients with chronic kidney disease. Method: This is a single centered observational prospective study done on 191 post coronary artery bypass grafting patients from June 2018 to April 2019 at Cardiac Surgery Unit of Doctor's hospital and medical center, Lahore, Pakistan. Patients above 18 years with and without chronic kidney disease were included. Results: Mean age of the patients was 57.83 years (± 9.862 SD. Logistic regression analysis shows that patients with post op arrhythmias had the strongest positive association with prolonged intensive care unit stay (OR:11; p value :<0.01), followed by recent myocardial infarction less than 90 days pre coronary artery bypass grafting (OR:5.93; p value:<0.01), shock (OR:3.93;p value:0.04) and acute kidney injury (OR :2.08;p value:0.04). 37.5% chronic kidney disease patients with recent myocardial infarction less than 90 days pre coronary artery bypass grafting and 51.4% patients of chronic kidney disease found with acute kidney injury, showed significant association with p values less than 0.05. Conclusion: Post op arrhythmias, recent myocardial infarction, shock and acute kidney injury are independent risk factors causing prolonged intensive care unit stay in post coronary artery bypass grafting patients.

An approximation of one-dimensional nonlinear Kortweg de Vries equation of order nine.

This research presents the approximate solution of nonlinear Korteweg-de Vries equation of order nine by a hybrid staggered one-dimensional Haar wavelet collocation method. In literature, the underlying equation is derived by generalizing the bilinear form of the standard nonlinear KdV equation. The highest order derivative is approximated by Haar series, whereas the lower order derivatives are attained by integration formula introduced by Chen and Hsiao in 1997. The findings are shown in the form of tables and a figure, demonstrating the proposed technique's convergence, robustness, and ease of application in a small number of collocation points.

Lactobacillus species signature in association with term and preterm births from low-income group of Pakistan.

AIM/PURPOSE OF STUDY: It is estimated that around 15 million babies are born prematurely every year and approximately one million children die each year due to complications of preterm birth (PTB). Many survivors face a lifetime of disability, including learning disabilities and visual and hearing problems. The current study aimed to characterize Lactobacillus species isolated from vaginal swabs and determine their antibiotic susceptibility. MATERIAL AND METHODS: 40 term and 20 preterm samples were processed by culturing on MRS agar and initial identification was carried out using sugar fermentation reactions and 16S rRNA PCR. Moreover, Lactobacillus species from preterm and term cases using paired samples, i.e. vaginal swabs and placenta tissues from 8 preterm delivering mothers were further recruited for metagenomics study to possibly detect uncultured Lactobacillus species known to cause PTB. RESULTS: 40% samples from preterm delivering mothers lack any Lactobacillus species whereas in contrast vaginal microflora of all term delivering mothers carry one or more species of Lactobacillus. L. crispatus (46% in term group and 25% preterm group) was found to be the most abundant group followed by L. jensenii (25% in both groups) and L. gasseri (19% in term group and 10% in preterm group). The antimicrobial susceptibility profile suggests that preterm isolates were least resistant to linezolid (20% resistance rate) and trimethoprim/sulfamethoxazole (22% resistant rate) compared to term isolates (>60% for each drug group). Furthermore, the metagenomics data for paired samples (8 VS and 8 PT) from extreme PTB suggested that Lactobacillus Iners was the main difference between term and preterm deliveries. Moreover, overall lack of lactobacillus species or presence of rogue Lactobacillus species such as L. iners and L. vaginilis is associated with PTB. ERIC-PCR analysis using Lactobacillus crispatus revealed that all the pre-term samples are closely related and fall in same cluster while all the term samples fall in different cluster. CONCLUSION: The study not only provides a baseline data of distinct signatures of associated lactobacillus species with the PTB which may be further transmitted to new born infants but also developing further therapeutic interventions to better manage the PTB.

A reliable algorithm to compute the approximate solution of KdV-type partial differential equations of order seven.

The approximate solution of KdV-type partial differential equations of order seven is presented. The algorithm based on one-dimensional Haar wavelet collocation method is adapted for this purpose. One-dimensional Haar wavelet collocation method is verified on Lax equation, Sawada-Kotera-Ito equation and Kaup-Kuperschmidt equation of order seven. The approximated results are displayed by means of tables (consisting point wise errors and maximum absolute errors) to measure the accuracy and proficiency of the scheme in a few number of grid points. Moreover, the approximate solutions and exact solutions are compared graphically, that represent a close match between the two solutions and confirm the adequate behavior of the proposed method.

Racial and gender disparities in neurology.

INTRODUCTION: The USA is a diverse society with representation from different ethnic and racial backgrounds, resulting in under-represented minorities (URMs) in various specialties of medicine. Our objective was to find the statistical ratio of URMs in the academic faculty of neurology. METHODS: This was a retrospective analysis of the American Association of Medical College database. The database covered neurology faculty members from 2006 to 2017. RESULTS: This study shows a significant change in racial representation in faculty ranks over the last 12 years. At chairperson rank, white people decreased from 86.4% to 79.8% whereas Asian, Hispanic and multiple races (non-Hispanic) simultaneously increased from 6.4% to 9.3%, 0.9% to 3.1% and 1.8% to 4.7%, respectively. At the professor rank, white people decreased from 87.4% to 81.6%, while Asians and Hispanics increased from 7.1% to 10.5% and from 0.7% to 2.1%, respectively. At the rank of associate professor, white people decreased from 81.1% to 68.3% whereas Asians, Hispanics and unknown races increased from 10.3% to 19.0%, 1.6% to 3.1% and from 2.1% to 3.5%, respectively. For the rank of assistant professor, white people decreased from 64.7% to 56.9% and Asians increased from 20.5% to 25.9%. Gender differences (men vs women) for the ranks of chairperson, professor, associate professor, assistant professor and instructors were 90.3% and 9.7%, 83.1% and 16.9%, 67.1% and 32.9%, 56.8% and 43.2%, and 48.1% and 51.9%, respectively. CONCLUSION: Over a period of 12 years the racial proportion in academic neurology has changed, but it is not proportionate to their respective increase in the population of the USA. Moreover, the portion of female faculty increased, but they are still under-represented in leadership roles. This racial and gender disparity can be addressed by well-planned interventions.

Artificial intelligence as an emerging technology in the current care of neurological disorders.

BACKGROUND: Artificial intelligence (AI) has influenced all aspects of human life and neurology is no exception to this growing trend. The aim of this paper is to guide medical practitioners on the relevant aspects of artificial intelligence, i.e., machine learning, and deep learning, to review the development of technological advancement equipped with AI, and to elucidate how machine learning can revolutionize the management of neurological diseases. This review focuses on unsupervised aspects of machine learning, and how these aspects could be applied to precision neurology to improve patient outcomes. We have mentioned various forms of available AI, prior research, outcomes, benefits and limitations of AI, effective accessibility and future of AI, keeping the current burden of neurological disorders in mind. DISCUSSION: The smart device system to monitor tremors and to recognize its phenotypes for better outcomes of deep brain stimulation, applications evaluating fine motor functions, AI integrated electroencephalogram learning to diagnose epilepsy and psychological non-epileptic seizure, predict outcome of seizure surgeries, recognize patterns of autonomic instability to prevent sudden unexpected death in epilepsy (SUDEP), identify the pattern of complex algorithm in neuroimaging classifying cognitive impairment, differentiating and classifying concussion phenotypes, smartwatches monitoring atrial fibrillation to prevent strokes, and prediction of prognosis in dementia are unique examples of experimental utilizations of AI in the field of neurology. Though there are obvious limitations of AI, the general consensus among several nationwide studies is that this new technology has the ability to improve the prognosis of neurological disorders and as a result should become a staple in the medical community. CONCLUSION: AI not only helps to analyze medical data in disease prevention, diagnosis, patient monitoring, and development of new protocols, but can also assist clinicians in dealing with voluminous data in a more accurate and efficient manner.

South Asian countries report the highest prevalence of common mental disorders (CMDs) globally. This systematic review and meta-analysis report the pooled prevalence of CMDs among the South Asian countries. Database searches were conducted in eight electronic databases. Titles, abstracts, full-text screening, and extraction of data on the event rate of 17 indicators of CMDs were performed by two independent reviewers. A total of 160 studies were included and data analysis was done using the Comprehensive Meta-analysis Software (v.3). A prevalence of depressive symptoms was 26.4% among 173,449 participants, alcohol abuse was 12.9% (n = 107,893); anxiety 25.8% (n = 70,058); tobacco smoking 18.6% (n = 84,965); PTSD 17.2% (n = 42,298); mixed anxiety and depression 28.4% (n = 11,102); suicidal behaviors 6.4% (n = 25,043); misuse of opiates 0.8% (n = 37,304); tobacco chewing 21.0% (n = 10,586); use of cannabis 3% (n = 10,977); GAD 2.9% (n = 70,058); bipolar disorder 0.6% (n = 7,197); IV drug abuse 2.5% (n = 15,049); panic disorder 0.01% (n = 28,087); stimulant use 0.9% (n = 1,414); OCD 1.6% (n = 8,784) and phobic disorders 1.8% (n = 27,754). This study reported a high prevalence of CMDs in South Asian countries; necessitating further research on psychiatric epidemiology in those contexts. It informs the need for effective policymaking and implementation of culturally appropriate multilevel interventions.

Cytokine Registry In Stroke Patients (CRISP): Protocol of a prospective observational study.

Inflammation is an important pathophysiological process after an acute stroke (AS). Pro- and anti-inflammatory molecules (cytokines and interleukins) are the key players during this mechanism. Emerging evidence indicate that these molecules can serve as biomarkers of stroke progression and outcome and as novel therapeutics agents. The aim of this study is to explore the temporal changes in these molecules and validate them as biomarker of AS progression and neurological outcome.The "Cytokine Registry In Stroke Patients (CRISP)" is a prospective cohort study of 600 AS patients presenting to the tertiary hospital with-in 24 h of the onset of symptoms. Plasma cytokines and interleukins will be collected at admission and 24 h after and will be measured using enzyme-linked immunosorbent assay (ELISA) to evaluate the difference in their variation among different gender, race and ethnicity and their association with various neurological outcomes. The primary exposures are biological sex (male, female) and race/ethnicity. Confounding variables include age, vascular risk factors, infarct size, stroke onset to presentation time, and identified stroke etiologies. Matched controls will be used for the comparison and evaluation of the difference among gender and race/ethnicities.CRISP is a prospective observational study that investigates the role and relationship of molecular biomarkers identifying specific and relevant targets pertinent for monitoring the progression and outcome in AS patients.Trial Registration: The study is registered on ClinicalTrial.gov: https://clinicaltrials.gov/ (NCT03297827).

Mitral Annular Calcification In Stage 5 Chronic Kidney Disease On Dialysis Therapy.

BACKGROUND: Mitral Annular Calcification (MAC) is a degenerative process involving the mitral valve and is a marker of advanced cardiovascular disease. Prevalence in the general population is upto 10% and increases in advanced age, diabetes mellitus, chronic kidney disease (CKD), end stage renal disease (upto 40%) and mitral valve prolapse.The aims of this study were to assess the prevalence of MAC in CKD5D patients and correlate with patients' characteristics. METHODS: Echocardiograms were obtained in 84 hemodialysis patients. Association of MAC with various patient characteristics was studied. Data was analysed using SPSS-22. RESULTS: The mean age of the patients was 63.38±12.3 years and 48 (57%) were males. Sixty-eight patients (81%) had DM and 79 (94%) had hypertension. MAC was present in 37 out of 84 (44%) patients. Sixty-four (72%) had IHD. The presence of MAC correlated significantly with IHD (Odds Ratio 6.42, p=0.006). Mean follow up of the patients was 30.30±29.22 months and 37 (44%) suffered mortality during this period. Patients on dialysis for longer than 36 months had an elevated risk of developing MAC (OR=3.32, p=0.019). Patients with the following risk factors: serum PO4 greater than 5.5 (OR=2.03), DM (OR=1.95), HTN (OR=3.35), Age >60 (OR=1.83), AFIB (OR=1.28); had an observable increase in incidence of MAC with time but they weren't statistically significant. CONCLUSIONS: Mitral Annular Calcification is common in hemodialysis patients and correlates significantly with IHD. Our findings support the recommendation by KDIGO 2017 guidelines on Mineral and Bone Disease on the use of echocardiography for the detection of valvular calcification.

Reduce Disease Burden of Human Schistosomiasis in Asia Through Biological Control.

Schistosomiasis is a chronic parasitic disease caused by a trematode blood fluke of the genus Schistosoma that belongs to the Schistosomatidae family. It is a neglected disease in different regions of Asia. In this review, 218 articles (between 2000 and 2017) related to the topic were collected from PubMed and Google scholar and reviewed. After thoroughly reading collected articles, due to irrelevant topic requirements, 94 articles were excluded. Articles that have data associated with Asian regions are considered. In Asia, the disease is prevalent in China, Philippines, Indonesia, Yemen, Nepal and Laos, etc. While in Pakistan, India and Bangladesh, the disease is not endemic and very few cases were reported. The disease was eliminated from Japan and Iran. The current review highlights the geographical distribution among Asian countries, transmission patterns, diagnosis, control strategies based on the use of anthelmintic plants and management practices implemented in Asia for the control of schistosomiasis. However, new implementations to treat schistosomiasis in humans should be proved to eliminate the disease finally in the future. This review emphasizes the biological control of schistosomiasis for the eradication of the disease from Asia in the near future.

Organization of Stroke Care in Pakistan.

In Pakistan, stroke is one of the major contributors to the health problem. The increasing incidence of stroke and lack of infrastructure in both urban and rural areas requires immediate attention. Multiple societies and groups have been established to highlight the growing problem, but necessary steps must be taken at the government level to improve and design a better stroke care system in the country.

Resistance profile of genetically distinct clinical Pseudomonas aeruginosa isolates from public hospitals in central Pakistan.

INTRODUCTION: Pseudomonas aeruginosa (member of ESKAPE group) is predominantly responsible for emerging nosocomial infections and poses serious health concern due to ever-increasing drug resistance trends. The current study investigates the prevalence of such highly resistant P. aeruginosa in major hospital settings and further characterizes and compares them for genetic heterogeneity. MATERIALS AND METHODS: Samples of patients (n=108) with wound infections, bacteremia and burn injuries from major hospitals of Rawalpindi and Islamabad during 2017 to 2018 were collected for the present study. The samples were processed in the COMSATS Microbiology and Public Health lab and screened for the P. aeruginosa by routinely used biochemical tests, drug susceptibility tests and rapid molecular approaches. RESULTS: The results suggested that most of the isolates (88/108) are indeed P. aeruginosa (81.4%) underpinning the need of its active surveillance in hospital settings. Further analysis suggested that 32 of these 88 microbes are multi-drug resistance (36.3%), 16 (18.1%) are extensively drug resistance and 4 (4.5%) are pan-drug resistance. Moreover, double disc synergistic test suggested that 16 (18.1%) are positive for metallo-ß-lactamase production. Molecular screening confirmed that 2 (12.5%) and 3 (18.75%) of these 16 isolates are positive for VIM and NDM gene respectively while all the studied isolates were positive for AmpC ß-lactamase. PAP17 isolate harbors both VIM and NDM genes. ERIC PCR profiling showed that majority of MDR bacteria fall in cluster II and III similarly XDR bacteria also fall in cluster II and III while PDR bacteria fall in cluster IV. CONCLUSION: This study revealed that majority of the isolates are multi drug resistant MDR and extensively drug resistant (XDR). However, the presence of some pan drug resistant (PDR) isolates among such small sample size screened is of utmost concern. Molecular typing of extremely resistant P. aeruginosa revealed high genetic diversity. Therefore, we suggest that regular monitoring and surveillance of such highly resistant P. aeruginosa in hospital settings will help to control their transmission and hence reduce the disease burden.
