Mood Disorders in the Wake of Traumatic Brain Injury: A Systematic Review.

Traumatic brain injury (TBI) frequently leads to a myriad of long-term consequences, among which mood disorders present a significant challenge. This systematic review delves into the complex interplay between TBI and subsequent mood disorders, focusing on research studies conducted over the past decade. Encompassing an age range from 12 years old to older adults (60+ years), our review aims to elucidate the epidemiological patterns, neurobiological mechanisms, and psychosocial factors that contribute to the development of mood disorders following TBI. By synthesizing the current literature, we seek to uncover the prevalence and clinical implications of this often-under-recognized comorbidity. For the quality appraisal of the reviewed articles, the Newcastle-Ottawa risk-of-bias tool and Scale for the Assessment of Narrative Review Articles (SANRA) checklist were employed. Ultimately, this review endeavors to provide a comprehensive understanding of the intricate relationship between TBI and mood disorders, offering insights crucial for improved management and intervention strategies in affected individuals.

Incidence of Type 2 Diabetes Mellitus in Transgender Individuals Undergoing Gender Affirming Hormonal Therapy: A Systematic Review.

Gender-affirming hormonal therapy (GAHT), which includes estrogen, testosterone, androgen agonists, is commonly used in transgender individuals to change their secondary sexual characteristics to align with their gender identity. However, this treatment could result in metabolic side effects that could increase the chances of acquiring type 2 diabetes mellitus. Thus, this study aims to compare differences in body mass index (BMI), insulin resistance, and the incidence of type 2 diabetes mellitus between cisgender and transgender individuals undergoing GAHT. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards, we conducted a systematic review searching through PubMed, Google Scholar, Medline (Medical Literature Analysis and Retrieval System Online), and ResearchGate for articles published between 2014 and 2024. The final search was conducted in February 2024. Out of the 3,934 articles reviewed, 11 were selected, focusing on insulin sensitivity/resistance, diabetes incidence, and BMI changes with GAHT. Although our result findings did not show clear evidence of increased diabetes incidence among GAHT patients, it was observed that GAHT does increase BMI and insulin resistance in transgender individuals. Notably, compared to transgender men, transgender women on GAHT were found to be more prone to insulin resistance. We recommend regularly monitoring insulin sensitivity parameters and HbA1c during GAHT to monitor metabolic side effects. Further research and more clinical trials are needed to confirm the GAHT's impact on insulin resistance and to evaluate its role in the onset of type 2 diabetes mellitus.

The Role of Etanercept in Controlling Clinical and Radiological Progression in Rheumatoid Arthritis: A Systematic Review.

Etanercept (ETN) is a disease-modifying anti-rheumatic drug (DMARD) used in the treatment of rheumatoid arthritis (RA) that works as a tumor necrosis factor inhibitor (TNF inhibitor) by blocking the effects of naturally occurring TNF. This review will evaluate the effect of ETN as a monotherapy or combination therapy with methotrexate (MTX) in the treatment of RA. This systematic review was carried out in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) 2020 guidelines. A systematic search was done on PubMed and Google Scholar from 1999 to 2023. Predefined eligibility criteria were set for selected studies, which include: free full-text articles published; randomized control trials (RCTs); systematic reviews and meta-analyses; and observational studies in a patient with RA treated with ETN as initial therapy or as an add-on to conventional disease-modified therapy. Hence, the data had been extracted, and a quality assessment of each study was done by two individual authors. When comparing patients who received 15-25 mg of MTX with those who also received 25 mg of ETN in combination, 71% achieved American College of Rheumatology 20 (ACR20) by 24 weeks, compared to 27% in the MTX and placebo groups (p<0.001), and 39% achieved American College of Rheumatology 50 (ACR50), compared to 3% in the placebo + MTX group (p<0.001). Low disease activity (DAS 28) was more common in patients who had both MTX and ETN (64.5% with DAS <2.4 and 56.3% with DAS 28 <3.2) compared to patients who received only one medication (44.4% with DAS <2.4 and 33.2% with DAS 28 <3.2 for ETN and 38.6% with DAS <2.4 and 28.5% with DAS 28 <3.2 for MTX, with P<0.01). ETN demonstrated smaller changes from baseline in the modified Sharp score (TSS) and erosion scores (ES) at 12 months and two years, as well as a decreased change in the ES score at one year (with a trend of P value = 0.06 for the TSS score), in comparison to those receiving DMARD. Reactions at the injection site (42% vs. 7%, P<0.001) were the only events that occurred significantly more frequently in the ETN plus-MTX group. Combining ETN and MTX appears to help control RA symptoms by decreasing the American College of Rheumatology (ACR) response and DAS score, as well as halting the disease's progression on X-rays. The most common adverse effects were reactions to ETN administered alone at the injection site, likely because of patient awareness of the treatment received. There was also concern about tuberculosis and malignancy, but no recent data is available. Therefore, a larger clinical trial with longer follow-up is required to ascertain long-term safety and benefits.

Folic Acid in the Treatment of Sickle Cell Disease: A Systematic Review.

Sickle cell disease (SCD) is a group of inherited genetic disorders that is caused by a mutation in the gene that codes for hemoglobin subunit ß. This systematic review aimed to evaluate the effect of folic acid in the treatment of SCD patients. We retrieved 3730 articles from PubMed, PubMed Central, Google Scholar, and ScienceDirect databases. We employed a search technique that involved framing keywords, such as folic acid, folate, and sickle cell illness, and the Medical Subject Headings (MeSH) strategy in PubMed. We chose research articles that had been published during the last 10 years, as well as case reports, systematic reviews and meta-analyses, literature reviews, randomized controlled trials, and observational studies. Exclusion criteria included paid full-text articles, abstracts, non-English studies, and patients who do not have SCD. The 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria were used in the design of our systematic review. It was found that the majority of SCD patients were receiving regular folic acid supplements and that their plasma folate levels were either increased or within normal range, with no discernible impact on other clinical outcomes such as hemoglobin levels, infections, or pain crises. SCD patients produce more red blood cells than healthy individuals, and nearly all SCD patients receive daily folic acid supplements. On the other hand, not enough information is available on folic acid's potential benefits in the management of SCD; thus, there is a need for more large clinical trials.

Amplatzer Patent Foramen Ovale Occluder Device-Related Complications.

Patent foramen ovale (PFO) is a standard variant that is present in 25% of the whole adult population. In a certain population, PFO can lead to cerebrovascular accidents. Mechanism of cerebrovascular accidents can be by paradoxical embolization from the right circulation or in situ thrombosis. Diagnosis of a PFO-responsible cerebrovascular accident is based on a thorough work-up to exclude other possible etiologies and detect PFO on trans-thoracic or trans-esophageal echocardiography with bubble study and/or Doppler. Over the last few years, multiple studies have supported that percutaneous PFO closure is superior to medical therapy in the secondary prevention of cerebrovascular accidents. However, numerous adverse events have been linked to PFO closure devices in general compared to medical therapy as new-onset atrial fibrillation, residual shunt, device-related thrombus, bleeding, deep vein thrombosis, pulmonary embolism, and inter-atrial septal erosions. Amplatzer device is one of the PFO occluder devices approved by the FDA. Device-related adverse events have been addressed by comparing the Amplatzer device with other PFO occluder devices. Based on the new data, we expect to see more complications related to PFO closure in the coming few years. We reviewed different studies that looked at the PFO closure-related complications and the trials comparing adverse events in the Amplatzer PFO occluder device compared to other devices. Amplatzer PFO occluder device is either superior or non-statistically different from other PFO occluder devices related to new-onset atrial fibrillation and residual shunt. More studies are needed to address the other less common adverse events. Since many of the device-related complications appear many years after device placement, a long-term follow-up is recommended.

[This corrects the article DOI: 10.7759/cureus.21331.].

The Role of Chlamydia Trachomatis in the Pathogenesis of Cervical Cancer.

Chlamydia trachomatis (CT) is an obligate intracellular, Gram-negative bacterium that causes a variety of infections in both humans and animals. It is the causative agent of one of the most common sexually transmitted infections (STIs) with sequelae such as pelvic inflammatory disease, ectopic pregnancy, and infertility. Furthermore, Chlamydia infections have been epidemiologically linked to cervical cancer (CC) in patients with human papillomavirus (HPV) coinfection. However, a molecular mechanism linking Chlamydia to CC is yet to be established, and we still do not know if more aggressive diagnosis and treatment of Chlamydia could possibly lead to lower incidences of CC and associated mortality. Since CC is a leading cause of death among women worldwide, and HPV infection alone is insufficient to cause cancer, our goal was to determine the link between Chlamydia, HPV, and CC. This literature review aimed to understand the pathologic model of CC and how Chlamydia might induce or promote carcinogenesis alone or alongside HPV. In addition, we compared multiple studies attempting to associate Chlamydial infection with CC in different populations and aimed to determine whether there is an epidemiological correlation or not.

Arrhythmic mitral valve prolapse: Diagnostic parameters for high-risk patients: A systematic review and meta-analysis.

BACKGROUND: Although frequently considered a benign condition, new evidence has shown that mitral valve prolapse (MVP) is associated with complex ventricular arrhythmias (VAs) and sudden cardiac death (SCD). Therefore, we conducted a systematic review and meta-analysis of the relevant studies to investigate the parameters that could identify MVP patients at higher risk of experiencing complex VAs. METHOD: We performed a systematic literature search of PubMed for potential studies between January 2010 and January 2021. Our meta-analysis included studies comparing MVP patients with complex VAs (A-MVP) and those without (NA-MVP). We used the fixed-effects model to obtain the odds ratio (OR), risk ratio (RR), or mean difference (MD) and 95% confidence interval (CI) for each analyzed parameter. RESULTS: Six studies with 848 individuals were included in the meta-analysis. As compared to the NA-MVP patients, A-MVP patients had a higher prevalence of inverted T-wave (OR: 2.73; 95% CI: 1.85-4.02; p < .00001) and longer QTc interval on the resting ECG (MD: 14.73; 95% CI: 9.39-20.08; p < .00001), longer anterior mitral leaflet length (MD: 2.67; 95% CI: 2.02-3.31; p < .00001), bi-leaflet prolapse (OR: 1.65; 95% CI: 1.22-2.24; p = .001), and mitral annulus disjunction (MAD) on echocardiogram (RR: 1.90; 95% CI: 1.50-2.40; p < .00001), and late gadolinium enhancement (LGE) on cardiac magnetic resonance (RR: 4.38; 95% CI: 1.77-10.86; p = .001). CONCLUSION: Our comprehensive meta-analysis suggests that risk factors related to A-MVP are T-wave inversion, longer QTc interval, bi-leaflet prolapse, longer anterior mitral valve leaflet, MAD, and LGE.

Subclinical Hypothyroidism in Geriatric Population and Its Association With Heart Failure.

Heart failure (HF) is one of the most common causes of hospitalization in the geriatric age group, above 65 years. It is associated with high morbidity, mortality, and bad prognosis. Subclinical hypothyroidism (SCH) is a common condition present in this age group that significantly affects the cardiovascular system. Thus, this review attempts to elaborate on the association between subclinical hypothyroidism and heart failure in terms of their prevalence, pathogenesis, prognosis, and possible management in a geriatric age group. Among the various published literature on this topic on PubMed, PubMed Central, and Google Scholar, 36 relevant studies were selected to correlate this association. We found that both SCH and HF can be present concurrently in this age group. Especially in the geriatric population with thyroid-stimulating hormone (TSH) higher than ten mIu/L, there is an increased incidence of heart failure and a worse prognosis with preexisting heart failure. However, randomized controlled trials will be needed to explore further whether treatment is warranted or not in this age group.

Post-Traumatic Seizures: A Deep-Dive Into Pathogenesis.

Post-traumatic seizures (PTS) have become an emerging challenge for neurologists worldwide with the rise of brain injuries. Trauma can lead to various outcomes, ranging from naive spasms to debilitating post-traumatic epilepsy (PTE). In this article, we will explore the pathogenesis of convulsions following a concussion. We will look at multiple studies to explain the various structural, metabolic, and inflammatory changes leading to seizures. Additionally, we will explore the association between severity and location of injury and PTE. PTE's pathophysiology is not entirely implicit, and we are still in the dark as to which anti-epileptic drugs will be useful in circumventing these attacks. The purpose of this narrative review is to explain the post-traumatic brain changes in detail so that such attacks can be either thwarted or treated more resourcefully in the future.
