Post-Hemorrhagic Hydrocephalus and Outcomes Amongst Neonates With Intraventricular Hemorrhage: A Systematic Review and Pooled Analysis.

Introduction Intraventricular hemorrhage (IVH) is a common cause of morbidity and mortality in preterm neonates. IVH leads to complications such as posthemorrhagic hydrocephalus (PHH), which commonly occurs in neonates with a more severe degree of IVH. Hence, we aimed to evaluate the characteristics and outcomes of PHH in neonates with IVH. Methods We performed a systematic review of cases reported from January 1978 to December 2020 through the PubMed database, using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and the keywords 'intraventricular hemorrhage,' 'cerebral intraventricular hemorrhage,' and 'newborn.' A total of 79 articles were considered for analysis, and data on neonatal and maternal characteristics and outcomes were collected. The analysis was performed by using the χ2 test, Wilcoxon rank-sum test, and multivariate logistic regression model. Results We analyzed a total of 101 IVH cases, 54.5% were male and 62.4% preterm. Thirteen point nine percent (13.9%) presented with grade I, 35.6% grade II, and grade III respectively, and 8% grade IV IVH. Among the 59 (58.4%) neonates with PHH, 33.6% had resolved PHH and 24.8% had unresolved. In adjusted regression analysis, we found that neonates with resolved PHH have lower odds of having neurodevelopmental delay (OR:0.15, 95%CI:0.03-0.74; p=0.02) and death (OR:0.9;95%CI:0.01-0.99; p=0.049) as compared to unresolved PHH. Conclusion Our study showed that neonates with resolved PHH have a statistically significant lower risk of neurodevelopmental delay (NDD) and mortality. Future studies should be planned to evaluate the role of treatment and its effect on outcomes in IVH neonates with PHH as a complication.

Forty Years Since the Epidemic: Modern Paradigms in HIV Diagnosis and Treatment.

Human immunodeficiency virus (HIV) is a viral infection that, when transmitted through the exchange of certain bodily fluids, destroys various immune cells and contributes to an overall weakened immune system. If left untreated, HIV progresses to acquired immunodeficiency syndrome (AIDS) - a chronic, life-threatening condition that puts patients at risk for opportunistic infections. Since the emergence of HIV nearly a century ago, the world has seen tremendous advances in elucidating its pathology and progression. These advances have been accompanied by an increased understanding of how subsequent effects and symptoms manifest in afflicted individuals. These discoveries, coupled with the ever-improving technologies and methodologies used for detection and treatment, provide the scientific and medical community with a solid grasp of HIV. Despite this significant headway, there is still much progress to be made; medical advances have allowed people with HIV to manage their disease and live a longer, healthier life, but a definite cure is yet to be found. Thus, the following literature review serves as both an extensive compendium of our current understanding of HIV - its pathology, testing/detection, repercussions, and treatment - and an acknowledgement of the areas that still require further research.

Recommended Strategies for Physician Burnout, a Well-Recognized Escalating Global Crisis Among Neurologists.

Several indexes are used to classify physician burnout, with the Maslach Burnout Inventory currently being the most widely accepted. This index measures physician burnout based on emotional exhaustion, detachment from work, and lack of personal achievement. The overall percentage of physicians with burnout is estimated to be around 40%, but the proportion varies between specialties. Neurology currently has the second-highest rate of burnout and is projected to eventually take the top position. The purpose of this review is to provide a comprehensive overview focusing on the causes and ramifications of burnout and possible strategies for addressing the crisis. Several factors contribute to burnout among neurologist, including psychological trauma associated with patient care and a lack of respect compared to other specialties. Various interventions have been proposed for reducing burnout, and this article explores the feasibility of some of them. Burnout not only impacts the physician but also has adverse effects on the overall quality of patient care and places a strain on the health-care system. Burnout has only recently been recognized and accepted as a health crisis globally, and hence most of the proposed action plans have not been validated. More studies are needed to evaluate the long-term effects of such interventions.

Biometals as Potential Predictors of the Neurodegenerative Decline in Alzheimer's Disease.

Alzheimer's Disease (AD) is a debilitating neurodegenerative disease that is diagnosed by gradual memory loss and certain cognitive impairments involving attention, reasoning, and language. Most of the research on Alzheimer's disease focuses on the correlation of its neuropathological changes in the neurofibrillary tangles caused by hyper-phosphorylated tau protein and ß-amyloid plaques with respect to cognitive impairment. Its pathology, however, remains incompletely understood. Currently, research has demonstrated that environmental factors such as biometals play a crucial role in exacerbating AD progression. The present review examines the role of metals in AD progression and how metal dyshomeostasis attributes to AD pathogenesis.  It was found that certain metals possess both beneficial and harmful properties in terms of AD progression. Depending upon the concentration of the metal of interest, copper, zinc, iron, and selenium have general beneficial properties. However, when present in excess, they can lead to oxidative stress and hyperphosphorylation of tau protein, amongst other harmful effects, while calcium and magnesium were seen to have beneficial effects by regulating biometal uptake.  In this review, we have provided evidential studies that focus on the involvement of certain metals in antioxidant pathways leading to the formation of reactive species indicative of neurodegeneration.

Hypocalcemia and Vitamin D Deficiency amongst Migraine Patients: A Nationwide Retrospective Study.

Background and Objectives: Inadequate vitamin D and calcium intake have been linked to many health issues including chronic headaches. Some studies suggested an association between low vitamin D levels and increase the risk of frequent headaches in middle-aged and older men; however, no single study reported the role of these deficiencies in migraine patients. We aimed to investigate the association of hypocalcemia and vitamin D deficiency with migraine hospitalizations. Materials and Methods: A population-based retrospective cross-sectional analysis of the Nationwide Inpatient Sample (NIS) (years 2003-2014) in migraine hospitalizations was performed. The prevalence, demographic characteristics and All Patient Refined Diagnosis Related Groups severity/disability association were compared in patients with hypocalcemia and vitamin D deficiency to those without deficiencies, using ICD-9-CM codes. Weighted analyses using Chi-Square, paired Student's t-test, and Cochran-Armitage trend test were performed. Survey logistic regression was performed to find an association between deficiencies and migraine hospitalizations and deficiency induced disability amongst migraineurs. Results: Between years 2003 and 2014, of the total 446,446 migraine hospitalizations, 1226 (0.27%) and 2582 (0.58%) presented with hypocalcemia and vitamin D deficiency, respectively. In multivariable analysis, hypocalcemia [Odds Ratio (OR): 6.19; Confidence Interval (CI): 4.40-8.70; p < 0.0001] and vitamin D deficiency (OR: 3.12; CI: 2.38-4.08; p < 0.0001) were associated with markedly elevated odds of major/extreme loss of function. There was higher prevalence (3.0% vs. 1.5% vs. 1.6%; p < 0.0001) and higher odds of migraine among vitamin D deficiency (OR: 1.97; CI: 1.89-2.05; p < 0.0001) patients in comparison to patients with hypocalcemia (OR: 1.11; CI: 1.03-1.20; p = 0.0061) and no-deficiency, respectively. Conclusions: In this study, we demonstrated a significant association between hypocalcemia and vitamin D deficiency with migraine attacks and deficiency induced loss of function among migraineurs. Early preventive measures may reduce the disability in migraineurs.
