Temporal Trends and Regional Variations in Mortality Related to Guillain-Barré Syndrome in the United States: A Retrospective Study From 1999 to 2020.

AimGuillain-Barré syndrome (GBS) is an autoimmune neurological disorder, with an estimated 6.4% increase in cases worldwide from 1990 to 2019. We aim to identify the GBS-related mortality trends in the US stratified by age, sex, race, and region.MethodsWe used data from the CDC-WONDER database to calculate crude (CMR) and age-adjusted mortality rates (AAMRs) per 1,000,000 people. We examined the temporal trends through annual percent change (APC) and the average annual percent change (AAPC) in rates using Joinpoint regression.ResultsFrom 1999 to 2020, a total of 10,097 GBS-related deaths occurred in the US. The AAMR decreased till 2014 (APC: -1.91) but increased back to initial levels by 2020 (APC: 3.77). AAMR was higher in males (1.7) than females (1.1), decreasing till 2015 for females and 2014 for males, but increasing thereafter only for females. Non-Hispanic (NH) American Indians or Alaska Natives displayed the highest AAMR (1.8) while NH Asians or Pacific Islanders displayed the lowest (0.6). AAMRs also varied by region (West: 1.5; South: 1.5; Midwest: 1.4; Northeast: 1.1). Rural regions exhibited a higher AAMR (1.7) than Urban regions (1.3). Most deaths occurred in medical facilities (60.99%). The adults aged ≥85 years exhibited an alarmingly high CMR (14.0).ConclusionsWhile the mortality rates for GBS initially declined till 2014, they climbed back up afterwards. Highest mortality was exhibited by males and NH American Indians or Alaska Natives, residents of rural regions, and adults ≥85 years. Equitable efforts are needed to reduce the burden on high-risk populations.

Magnetic Resonance-guided Laser Interstitial Thermal Therapy in the Management of Hypothalamic Hamartomas: A Systematic Review and Meta-analysis.

INTRODUCTION: Magnetic resonance-guided laser interstitial thermal therapy (MRg-LITT) is a promising new technique to ablate epileptic foci in patients with hypothalamic hamartoma (HH). We aim to systematically synthesize all available evidence and determine the effectiveness of MRg-LITT in reducing seizures in patients with HH. METHODS: We systematically searched MEDLINE (PubMed), Embase (Ovid), Scopus, and Google Scholar for all relevant articles. We used Open[Meta]Analyst to pool the number of seizure free patients after MRg-LITT treatment in a Random Effects model. Risk ratios (RRs) were calculated, and subgroups were analyzed. Comprehensive Meta Analysis was used to assess publication bias via funnel plots, Egger's regression test and Begg's correlation test. This review complies with the PRISMA guidelines. RESULTS: After screening the titles, abstracts, and full texts, we included seventeen articles in our meta-analysis, which revealed a 77.1% rate of seizure freedom (95% CI 0.696 to 0.837, p < 0.001), with moderate heterogeneity (I2 = 49.46%). Subgroup analysis by study design and sensitivity analyses excluding one study at a time did not impact the results substantially, and we found no evidence of publication bias. Adverse effects included electrolyte imbalances, weight gain, and transient neurologic disturbances. CONCLUSION: Magnetic resonance-guided laser interstitial thermal therapy might be a feasible and effective technique for ablation of epileptic foci, leading to seizure freedom in a large proportion of patients with hypothalamic hamartoma. However, there is a paucity of literature on the topic, and prospective clinical trials with larger number of participants, comparing MRg-LITT to open surgery, are needed.

Environmental Heavy Metal Exposure and Associated Cardiovascular Diseases in Light of the Triglyceride Glucose Index.

Cardiovascular diseases (CVD), primarily ischemic heart disease and stroke, remain leading global health burdens. Environmental risk factors have a major role in the development of CVD, particularly exposure to heavy metals. The Triglyceride Glucose Index (TyG), a measure of insulin resistance and CVD risk, is the primary focus of this study, which summarizes the most recent findings on the effects of lead (Pb), arsenic (As), and cadmium (Cd) on CVD risk. A higher risk of CVD is correlated with an elevated TyG index, which has been linked to insulin resistance. Exposure to Cd is associated with disturbance of lipid metabolism and oxidative stress, which increases the risk of CVD and TyG. Exposure reduces insulin secretion and signaling, which raises the TyG index and causes dyslipidemia. Pb exposure increases the risk of CVD and TyG index via causing oxidative stress and pancreatic ß-cell destruction. These results highlight the need of reducing heavy metal exposure by lifestyle and environmental modifications in order to lower the risk of CVD. To comprehend the mechanisms and create practical management plans for health hazards associated with heavy metals, more study is required.

Huntington's Disease-Related Mortality Patterns: A Two-Decade Analysis of Mortality Trends in the United States, from 1999-2019.

Background: Huntington's disease (HD) is an autosomal dominant, progressive neurodegenerative disorder debilitating mainly in adults. Objective: This study aimed to assess the trends in HD-related mortality regarding various demographic factors. Methods: Death certificates from the CDC WONDER were studied from 1999 to 2019, for HD-related mortality in adults aged 25 + years. Age-adjusted Mortality Rate (AAMR) per 100,000 persons and Annual Percentage Change (APC) were calculated and stratified by year, age groups, gender, race/ethnicity, state, census region, urbanization, and place of death. Results: Between 1999 to 2019, 22,595 deaths occurred in adults due to HD. The AAMR increased from 0.43 to 0.54 during this period (APC = 0.50; 95% CI: 0.18 to 0.84). Old adults (65-85 + years) had the highest overall AAMR, followed by middle-aged adults (45-64 years) and young adults (25-44 years) (AAMR old: 1.01 vs. AAMR middle-age: 0.68 vs. AAMR young: 0.16). Men had slightly greater overall AAMRs than women (AAMR men: 0.54 vs. AAMR women: 0.48). When stratified by race, non-Hispanic (NH) Whites had significantly higher mortality rates than NH African Americans (AAMR NH White: 0.61 vs. NH African American: 0.35), while the AAMR were lowest in Hispanic/Latino (0.28). The AAMRs also showed variation by region (overall AAMR: Midwest: 0.63, Northeast: 0.47, West: 0.48, South: 0.46), and non-metropolitan areas had higher HD-related AAMR (0.66) than metropolitan areas (0.47). Conclusions: HD-related mortality in US adults has increased since 1999. Reflecting on the variations in trends observed, new strategies are required to optimize the quality of care in long-term care facilities.

Trends in mortality due to multiple sclerosis in the United States: A retrospective analysis from 1999 to 2020.

BACKGROUND: Multiple sclerosis (MS) is a neuroinflammatory condition with a prevalence of about 309.2 per 100,000 people in the United States. We aim to identify MS-related mortality trends in the USA from 1999 to 2020, stratified by age, sex, race, and geography, and its correlation with sunlight. METHODS: Death certificates from the CDC-WONDER database were examined for adults aged ≥25 years. Crude rates (CR) and age-adjusted mortality rates (AAMRs) per 1,000,000 persons and annual percent change (APC) were calculated. We also retrieved data for daily sunlight from 1999 to 2011. RESULTS: From 1999 to 2020, a total of 121,694 deaths occurred due to MS. The AAMR rose from 23.6 in 1999 to 29.7 in 2020 (APC 0.65), with a stable trend till 2018 (APC -0.22) followed by an abrupt increase towards 2020 (APC 9.27). Women had higher AAMR than men. Non-Hispanic (NH) Whites exhibited the highest AAMR (28.5), followed by NH Blacks (25.9), NH American Indians/Alaska Natives (9.6), Hispanics or Latino (6.8), and NH Asian or Pacific Islanders (1.9). AAMRs also varied substantially by region (Midwest: 32.4; Northeast: 26.9; West: 26.2; South: 19.4). States with the highest AAMRs were Montana, Wyoming, Colorado, and Oregon. The states with lower daily sunlight had higher AAMRs (r = -0.559, p = 0.000). AAMRs were comparable in urban (25) and rural (26.3) areas. Most deaths occurred in medical facilities (33.92 %) and nursing homes / long-term care (30.80 %), followed by home (27.79 %), and hospice (4.06 %). Adults ≥ 65 years depicted the highest mortality rates (CR 64.4) while adults aged 25 to 44 years showed the lowest rates (CR 4.6). CONCLUSION: We found an overall stable trend in MS-related mortality rates in the US till 2018 with a sharp increase thereafter. We observed highest mortality among women and NH White adults, among residents of Midwest and Northeast regions, and among adults ≥ 65 years. Higher disease burden in recent years calls for devising timely policies focused on these high-risk populations.

Temporal and regional trends in adults with diabetics kidney disease in the US from 1999 to 2020.

AIMS: We aim to analyze trends in mortality rates among adults with diabetic kidney disease (DKD) in the US from 1999 to 2020. METHODS: We queried the Centers for Disease Control Wide-Ranging Online Data for Epidemiologic Research database for mortality statistics from 1999 to 2020 associated with DKD in adults aged ≥25 years. Age-adjusted mortality rates (AAMRs) were calculated and trends were analyzed using the Joinpoint Regression Program. RESULTS: From 1999 to 2020, a total of 528,430 deaths were reported among adults with DKD. The mortality rates increased over time with males consistently exhibiting higher AAMR than females. NH American Indian or Alaska Native individuals had the highest AAMR, followed by NH Blacks, Hispanics, NH Whites, and NH Asians. The West region had the highest AAMR, followed by the Midwest, South, and Northeast. Rural regions had higher AAMR than urban areas, and mortality rates increased with age. CONCLUSIONS: This study reveals notable disparities in DKD mortality rates across demographic groups and geographic regions. NH American Indians or Alaska Natives, males, elderly individuals, rural residents, and those in the West region were disproportionately affected. Understanding these trends is crucial for developing targeted interventions to reduce DKD-related mortality and address healthcare disparities.

Bevacizumab Combination Therapy Versus Standard Chemotherapy for Ovarian Cancer in Shorter and Longer Follow-Up Duration: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

OBJECTIVE: This systematic review and meta-analysis aims to evaluate the efficacy and safety of bevacizumab in patients with ovarian cancer over a shorter and longer follow-up period. METHODS: We searched Medline, Cochrane CENTRAL, Scopus, and Google Scholar for all phase 3 randomized controlled trials (RCTs) that administered bevacizumab to women with ovarian cancer. Review Manager 5.4 was used to calculate risk ratios (RR) and hazard ratios (HR) with 95% CIs. We assessed the quality of the included studies using version 2 of the Cochrane Risk of Bias tool (RoB 2). RESULTS: After screening the titles, abstracts, and full texts, we included nine RCTs in our systematic review and meta-analysis. Four RCTs had a low risk of bias, while 5 had some concerns. Bevacizumab was associated with a progression free survival benefit for <36 months (HR: 0.59, 95% CI: 0.45-0.76, P <0.0001, I2 =90%) and >36 months (HR: 0.66, 95% CI: 0.55-0.80, P <0.0001, I2 =80%), and an overall survival benefit for <36 months (HR: 0.87, 95% CI: 0.78-0.98, P =0.02, I2 =0%) but not for >36 months (HR: 0.98, 95% CI: 0.89-1.09, P =0.77, I2 =30%). There was no difference in deaths between intervention and control groups <36 months (RR: 0.95, 95% CI: 0.86-1.04, P =0.26, I2 =10%) or >36 months (RR: 1.02, 95% CI: 0.97-1.06, P =0.50, I2 =0%). Bevacizumab reduced disease progression <36 months (RR: 0.82, 95% CI: 0.72-0.92, P =0.0008, I2 =82%) but not at >36 months (RR: 0.83, 95% CI: 0.58-1.19, P =0.30, I2 =94%). The adverse events reported with Bevacizumab use included thrombocytopenia, neutropenia, leukocytopenia, anemia, hypertension, bleeding or hemorrhage, and gastrointestinal, cardiac, and dermatological adverse events. CONCLUSION: Bevacizumab may improve progression-free survival within and after 36 months, overall survival within 36 months, and reduce disease progression within 36 months.

Disparities in mortality trends of adults with HIV in the USA: A comprehensive examination across 2 decades.

Approximately 38 million people worldwide are affected by human immunodeficiency virus (HIV), with 4000 new infections daily. While literature explores HIV mortality among the elderly in the US, there is an underrepresentation of mortality data for adults. By scrutinizing mortality trends based on demographic factors such as gender, race or ethnicity, age groups, and geographic location, the study seeks to uncover patterns that may facilitate a longitudinal perspective for tailoring interventions and allocating resources effectively. Crude death rates and age-adjusted mortality rates (AAMR) per 100,000 individuals were calculated using HIV mortality data (ICD-10 Codes B20-24) from CDC WONDER database. Permutation test was used to calculate annual percentage changes in AAMR with 95% confidence interval. Average annual percentage changes were computed as weighted average of annual percentage changes. Between 1999 to 2020, US adult HIV deaths totaled 225,396 (AAMR: 5.03), with a significantly decreasing average annual percentage changes (-5.94). Males exhibited a 3-fold higher AAMR (7.50) than females (2.67). Non-Hispanic Blacks had the highest AAMR (21.82), while Non-Hispanic Asians had the lowest (0.67). The South and Northeast regions had the highest AAMRs (6.91 and 6.33, respectively). Notably, the District of Columbia had an alarmingly high mortality rate of 39.9, while North Dakota had the lowest (0.7). Urban regions (5.47) had double the mortality rates of rural regions (2.70). Mortality rate peaked in age groups 45 to 54 (8.65) and 35 to 44 (7.42). While overall HIV mortality is declining, disparities persist among demographics. Targeted interventions are crucial to improve preventive measures and healthcare access for disproportionately affected groups.

Mortality patterns in older adults with infective endocarditis in the US: A retrospective analysis.

BACKGROUND: Infective Endocarditis (IE) has become a significant cause of morbidity and mortality over the last two decades. Despite management advancements, mortality trends in the USA's geriatric population are unexplored. The aim of this study was to assess the trends and regional differences in IE related mortality among geriatric patients in the USA. METHODS: We analyzed death certificates sourced from the CDC WONDER database spanning 1999 to 2020. The research targeted individuals aged 65 and older. Age-adjusted mortality rates (AAMRs) per 100,000 and annual percent change (APC), along with 95% CI, were calculated through joinpoint regression analysis. RESULTS: From 1999 to 2020, infective endocarditis caused 222,573 deaths, showing a declining trend (APC: -0.8361). Males had higher AAMR (26.8) than females (22.2). NH White had the highest AAMR (25.8), followed by NH American Indians or Alaska Natives (19.6). Geographically, the Midwest had the highest AAMR (27.4), followed by the Northeast (25.8). Rural areas consistently had higher AAMRs (26.6) than urban areas (23.6), while 80.16% of deaths occurring in urban settings. North Dakota, Nebraska, and Montana had the highest state AAMRs, approximately double than the states with the lowest mortality rates: Mississippi, Hawaii, California, and Massachusetts. Those aged 85 and above accounted for 42.9% of deaths. CONCLUSION: IE mortality exhibited a clear pattern: rising till 2004, declining from 2004 to 2018, and increasing again till 2020. Key risk factors were male gender, Midwest residence, NH White ethnicity, and age ≥85.Targeted interventions are essential to reduce IE mortality, especially among vulnerable older populations.

Tirzepatide: A novel cardiovascular protective agent in type 2 diabetes mellitus and obesity.

Cardiovascular disease (CVD) remains a major global health concern, and obesity and diabetes mellitus have been found to be important risk factors. Tirzepatide a dual glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP1) receptor agonist has been shown to have cardioprotective effects. Noteworthy benefits of Tirzepatide include decreased cardiovascular risk factors in people with Type 2 diabetes mellitus (T2DM). In the SURPASS-4 trial, tirzepatide significant decreased blood pressure, body weight, and HbA1c. Furthermore, the SURMOUNT-1 trial demonstrated the effectiveness of tirzepatide in reducing cardiometabolic risk factors in people with obesity without T2DM. Together, the dual receptor agonism improves lipid profiles, increases insulin secretion, reduces inflammation, and promotes endothelial integrity. Tirzepatide shows promise as a comprehensive therapeutic option for managing cardiovascular risk factors in patients with T2DM and obesity. While further studies are needed to assess the long-term cardiovascular benefits, current evidence supports tirzepatide's potential impact on cardiovascular health beyond its antidiabetic properties.

Efficacy of Cisplatin-Containing Chemotherapy Regimens in Patients of Pancreatic Ductal Adenocarcinoma: A Systematic Review and Meta-analysis.

BACKGROUND: The relative success of cisplatin-based chemotherapy regimens for PDAC in clinical trials warrants a review of the literature to assess the cumulative results. This study aims to assess the efficacy of cisplatin-containing regimens for PDAC in terms of survival and response outcomes using a systematic review and proportional meta-analysis. METHODS: In this study, an electronic search was conducted on PubMed, Cochrane Library, Scopus, and Google Scholar to find relevant literature. The random effects model was used to assess pooled overall response rate, stable disease rate, progressive disease rate, 1-year overall survival rate, and their 95% CIs. Publication bias was assessed using funnel plot symmetry and the one-tailed Eggers' test. In all cases, p-value < 0.05 was indicative of significant results. The review is registered with PROSPERO: CRD42023459243. RESULTS: A total of 34 studies consisting of 1599 patients were included in this review. All the included studies were of good quality. In total, 906 patients were male, and the median age of the patients was 58-69 years. Overall, 599 patients had cancer of the pancreatic head, 139 had cancer of the pancreatic body, and 102 patients had cancer of the pancreatic tail. The pooled risk ratios (RRs) revealed an overall response rate of 19.2% (95% CI, 14.6-24.2%), a stable disease rate of 42.3% (95% CI, 36.6-48.8), a 1-year overall survival rate of 40% (95% CI, 34.3-45.8), and progressive disease rate of 24.7% (95% CI, 18.8-31.2). Commonly reported adverse events were anemia, thrombocytopenia, abdominal adverse events, neutropenia, fatigue, leukopenia, alopecia, anorexia, mucositis, stomatitis, and hepatobiliary adverse events. CONCLUSION: Cisplatin-containing regimens have shown moderate efficacy with significant improvement in overall survival at 1 year, stable disease rate, and progressive disease rate; however, only a small percentage of patients achieved an overall response rate.

The Efficacy of Ketoconazole Containing Regimens in Castration-Resistant Prostate Cancer: A Systematic Review and Meta-Analysis.

Castration resistant prostate cancer (CRPC) is a challenging subset of prostate cancer associated with an extensive metastatic profile and high mortality. Ketoconazole is a nonselective steroid 17α-hydroxylase/17,20 lyase (CYP17A1) inhibitor and is employed as a second line treatment option for CRPC with an established efficacy profile in patients. The aim of this study is to assess the efficacy of ketoconazole containing regimens for CRPC in terms of prostate specific antigen (PSA) decline rate using a systematic review and meta-analysis. In this review, an electronic search was carried out on PubMed, Cochrane CENTRAL, Scopus, and Google Scholar to find relevant literature. Random effects model was used to assess pooled PSA decline rate and 95% CIs. Publication bias was assessed using the funnel plot symmetry and one-tailed Egger's and Begg's test. In all cases, P-value <.05 was indicative of significant results. The review is registered with PROSPERO: CRD42023466536. A total of 483 articles were retrieved after database searching, out of which 23 studies (having a total of 1315 patients) were included in the review based on prespecified criteria. The PSA decline rate was reported in the 14 observational studies (having 964 patients) and 9 experimental studies (having 351 patients). Pooled results revealed that 48.6% (95% CI 43.1-54.2; P-value <.001; I2 = 73.24%) of participants achieved more than 50% decline in PSA (602/1315 participants). Sensitivity analysis using the leave-one-out method revealed no substantial change in pooled effect estimates; (Risk Ratio) RR 47.2% to RR 49.8% demonstrating the robustness of our results. There was no evidence of publication bias as assessed from the funnel plot symmetry. Ketoconazole containing regimens have shown moderate efficacy in high risk CRPC patients as demonstrated by the pooled results. Hence, a ketoconazole based chemotherapy can be added to patients' regimen if there is a persistent rise in PSA levels after androgen deprivation therapy.

Cardiac autonomic plexus neuromodulation for decompensated heart failure: An updated review on the positive inotropic technique based on the DRI2P2S classification.

Current pharmacological regimen is unable to improve adverse outcomes such as mortality post hospitalization for Acutely Decompensated Heart Failure (ADHF) patients. Ongoing research is directed towards managing ADHF patients with Cardiac Autonomic Nervous System (CANS) excitatory interventions having long-term prognosis benefits. Recently, a novel treatment coined as Cardiac Pulmonary Nerve Stimulation (CPNS) has reproducibly shown increased inotropy with no change in heart rate. However, there are some potential limitations associated with the neurostimulation of the parasympathetic component of the CANS plexus. The INOVATE-HF trial involved the vagus nerve only. The early termination of the INOVATE-HF trial gave valuable insights into the cardio-protective effect of simultaneously stimulating the sympathetic and parasympathetic components of the CANS plexus done in CPNS. It is essential to individualize the treatment protocol keeping in mind patient selection. Ongoing trials assessing the efficacy and safety of the CPNS technique in ADHF patients shall set the tone for such innovative techniques in times to come.
