Intestinal microbiome as a diagnostic marker of coronary artery disease: a systematic review and meta-analysis.

Background: The intestinal microbiome has been recently linked to several metabolic and chronic disorders, one of which is coronary artery disease (CAD). Our study aimed to analyze the intestinal microbiome of CAD patients and assess the eligibility of dysbiosis as a diagnostic marker of CAD. Methods: PubMed, Scopus, Embase, and Web of Science were searched using terms, such as 'CAD' and 'microbiome'. Only observational controlled studies were included. R version 4.2.2 was used for the analysis. Results: A significant association was found between the CAD group and increased Simpson and Shannon Indices compared with the control group (MD=0.04, 95% CI=0.03-0.05, and MD=0.11, 95% CI=0.01-0.22, respectively). Our analysis yielded a statistically significant association between the CAD group and increased Prevotella genus (MD=13.27, 95% CI=4.12-22.42, P-value=0.004), Catenibacterium genus (MD=0.09, 95% CI=0.09-0.10), Pseudomonas genus (MD=0.54, 95% CI=0.29-0.78, P-value), and Subdoligranulum (MD=-0.06, 95% CI=-0.06 to -0.06) compared with the control group. Another significant association was detected between the CAD group and decreased Bacteroides vulgatus and Bacteroides dorei (MD=-10.31, 95% CI=-14.78 to -5.84, P-value <0.00001). Conclusion: Dysbiosis is an acceptable diagnostic marker of CAD. Decreased B. dorei and B. vulgatus among CAD patients suggests a protective role of these bacteria. Future clinical trials are necessary to investigate the potential benefit of supplementation of these bacteria in treating or preventing CAD.

Beyond Glycemic Control: GLP-1 Receptor Agonists and Their Impact on Calcium Homeostasis in Real-World Patients.

Background/Objectives: The effect of glucagon-like peptide-1 receptor (GLP-1R) agonists on calcium homeostasis is poorly understood. This study aimed to investigate the association between GLP-1R agonist use and the risk of hypocalcemia and/or hypercalcemia, as well as other clinical outcomes. Methods: A retrospective cohort study used de-identified patient data from the TriNetX Global Collaborative Network, including 15,655 adult patients prescribed GLP-1R agonists and 15,655 propensity-matched controls. Outcomes included hypocalcemia, hypercalcemia, emergency visits, hospitalizations, cardiovascular events, and all-cause mortality. Results: GLP-1R agonist use was associated with a reduced risk of hypocalcemia (2.7% vs. 5.5%, RR 0.49, 95% CI: 0.44-0.55) but an increased risk of hypercalcemia (2.3% vs. 1.1%, RR 2.02, 95% CI: 1.69-2.42). The effect on hypocalcemia was most pronounced during the first six months of treatment. Among individual agents, tirzepatide showed the most pronounced effect, reducing hypocalcemia risk by 63% while increasing hypercalcemia risk by 85%. Semaglutide demonstrated similar effects, while dulaglutide and liraglutide showed modest effects. Furthermore, GLP-1R agonist use was associated with reduced risks of emergency visits (RR 0.57, 95% CI: 0.54-0.60), hospitalizations (RR 0.40, 95% CI: 0.36-0.44), cardiovascular events, and all-cause mortality (HR 0.27, 95% CI: 0.21-0.36). Conclusions: GLP-1R agonists exhibit a complex influence on calcium homeostasis, reducing hypocalcemia risk while increasing hypercalcemia risk. Beyond calcium regulation, these medications significantly reduce healthcare utilization, improve cardiovascular outcomes, and decrease mortality. Further research is needed to elucidate the mechanisms behind the differential effects of individual GLP-1R agonists, particularly tirzepatide, to optimize personalized treatment approaches and long-term safety.

Association Between Type 1 Diabetes Mellitus and Eating Disorders: A Systematic Review and Meta-Analysis.

BACKGROUND: Previous meta-analyses have shown mixed results regarding the association between eating disorders (EDs) and type 1 diabetes mellitus (T1DM). Our paper aimed to analyse different EDs and disordered eating behaviours that may be practiced by patients with T1DM. METHODS: A literature search of PubMed, Scopus and Web of Science was conducted on 17 January 2023, using the key terms "T1DM," "Eating Disorders" and "Bulimia." Only observational controlled studies were included. The Revman software (version 5.4) was used for the analysis. RESULTS: T1DM was associated with increased risk of ED compared with nondiabetic individuals (RR = 2.47, 95% CI = 1.84-3.32, p-value < 0.00001), especially bulimia nervosa (RR = 2.80, 95% CI = 1.18-6.65, p-value = 0.02) and binge eating (RR = 1.53, 95% CI = 1.18-1.98, p-value = 0.001). Our analysis has shown that increased risk of ED among T1DM persisted regardless of the questionnaire used to diagnose ED; DM-validated questionnaires (RR = 2.80, 95% CI = 1.91-4.12, p-value < 0.00001) and generic questionnaires (RR = 2.03, 95% CI = 1.27-3.23, p-value = 0.003). Prevalence of insulin omission/misuse was 10.3%; diabetic females demonstrated a significantly higher risk of insulin omission and insulin misuse than diabetic males. CONCLUSION: Our study establishes a significant and clear connection between EDs and T1DM, particularly bulimia and binge eating, with T1DM. Moreover, female diabetics are at higher risk of insulin misuse/omission. Early proactive screening is essential and tailored; comprehensive interventions combining diabetes and ED components are recommended for this population, with referral to a specialised psychiatrist.

Adherence to antihypertensives in the United States: A comparative meta-analysis of 23 million patients.

Adherence to antihypertensives is crucial for control of blood pressure. This study analyzed factors and interventions that could affect adherence to antihypertensives in the US. PubMed, Scopus, Web of Science, and Embase were searched on January 21, 2022 and December 25, 2023 for studies on the adherence to antihypertensives in the US. Nineteen studies and 23 545 747 patients were included in the analysis, which showed that adherence to antihypertensives was the highest among Whites (OR: 1.47, 95% CI 1.34-1.61 compared to African Americans). Employment status and sex were associated with insignificant differences in adherence rates. In contrast, marital status yielded a significant difference where unmarried patients demonstrated low adherence rates compared to married ones (OR: 0.8, 95% CI 0.67-0.95). On analysis of comorbidities, diabetic patients reported lower adherence to antihypertensives (OR: 0.95, 95% CI 0.92-0.97); furthermore, patients who did not have Alzheimer showed higher adherence rates. Different BMIs did not significantly affect the adherence rates. Patients without insurance reported significantly lower adherence rates than insured patients (OR: 3.93, 95% CI 3.43-4.51). Polypill users had higher adherence rates compared with the free-dose combination (OR: 1.21, 95% CI 1.2-1.21), while telepharmacy did not prove to be as effective. Lower adherence rates were seen among African Americans, uninsured, or younger patients. Accordingly, interventions such as fixed-dose combinations should be targeted at susceptible groups. Obesity and overweight did not affect the adherence to antihypertensives.

Early oral feeding and its impact on postoperative outcomes in head and neck cancer surgery: a meta-analysis.

BACKGROUND: Early oral feeding has been previously postulated to contribute to developing postoperative complications following head and neck reconstructive surgeries using free flaps. This study assessed the association between the timing of oral feeding (early vs. late) and postoperative complications and length of hospital stay among these patients. METHOD: PubMed, Scopus, Cochrane, and Web of Science were searched using terms such as "oral feeding" and "head or neck cancer." We utilized RevMan software version 5.4 for the analysis. The study defined early oral feeding as feeding within 5-day post-operation, while late oral feeding was defined as feeding after the fifth postoperative day. Five papers that met the inclusion criteria were included in the analysis, with 1097 patients. RESULTS: The results showed that early feeding was not significantly associated with postoperative fistulas (RR 0.49, 95% CI 0.23 to 1.05, p-value = 0.07), hematoma/seroma (RR 0.71, 95% CI 0.33 to 1.51, p-value = 0.38), or flap failure (RR 0.84, 95% CI = 0.38 to 1.87, p-value = 0.67). However, early oral feeding was significantly associated with shorter hospital stays than late oral feeding (MD -3.18, 95% CI -4.90 to -1.46, p-value = 0.0003). CONCLUSION: No significant difference exists between early and late oral feeding regarding the risk of postoperative complications in head and neck cancer (HNC) patients who underwent free flap reconstruction surgery. However, early oral feeding is significantly associated with a shorter hospital stay than late oral feeding. Thus, surgeons should consider implementing early oral feeding after free flap reconstruction in HNC patients.

Physical activity patterns among obese adults attending rural primary health care units, Ismailia Governorate, Egypt: A case-control study.

Obesity is an ignored health problem in all countries; there are a lot of health problems related directly or indirectly to overweight and obesity. The incidence of COVID-19 with social isolation and technological development in recent years strongly contributed to a progressive increase in obesity. . Assess the pattern of the 3 divisions of physical activity and sedentary behaviors in obese patients. Physical inactivity is a significant concern, especially among individuals with obesity and certain demographic characteristics. Addressing these factors and promoting physical activity interventions tailored to specific populations is essential in combating sedentary behavior and its associated health implications.This case-control study included 350 adult obese patients (BMI ≥ 30) and 75 people with normal BMI (18.5-24.9). Their sociodemographic data were analyzed and their pattern of physical activity related to work, movement to and from places for 10 minutes, and pattern of recreational activity were assessed, in addition to the assessment of the sedentary behaviors. The mean age of the study group was 34 years, the majority were females, educated, and working. Forty five percent of the total sample were physically inactive; the pattern of activity during travel to and from places (10 min) was lower in obese patients. Recreational activities were low in the studied population, in the present study the time spent sitting or reclining (except sleeping) was significantly higher among obese participants than controls (P ≤ .001). Obesity, urban residence, unemployment and illiteracy were independent risk factors for physical inactivity.

The use of protective mechanical ventilation during extracorporeal membrane oxygenation for the treatment of acute respiratory failure.

Acute respiratory failure (ARF) strikes an estimated two million people in the United States each year, with care exceeding US$50 billion. The hallmark of ARF is a heterogeneous injury, with normal tissue intermingled with a large volume of low compliance and collapsed tissue. Mechanical ventilation is necessary to oxygenate and ventilate patients with ARF, but if set inappropriately, it can cause an unintended ventilator-induced lung injury (VILI). The mechanism of VILI is believed to be overdistension of the remaining normal tissue known as the 'baby' lung, causing volutrauma, repetitive collapse and reopening of lung tissue with each breath, causing atelectrauma, and inflammation secondary to this mechanical damage, causing biotrauma. To avoid VILI, extracorporeal membrane oxygenation (ECMO) can temporally replace the pulmonary function of gas exchange without requiring high tidal volumes (VT) or airway pressures. In theory, the lower VT and airway pressure will minimize all three VILI mechanisms, allowing the lung to 'rest' and heal in the collapsed state. The optimal method of mechanical ventilation for the patient on ECMO is unknown. The ARDSNetwork Acute Respiratory Management Approach (ARMA) is a Rest Lung Approach (RLA) that attempts to reduce the excessive stress and strain on the remaining normal lung tissue and buys time for the lung to heal in the collapsed state. Theoretically, excessive tissue stress and strain can also be avoided if the lung is fully open, as long as the alveolar re-collapse is prevented during expiration, an approach known as the Open Lung Approach (OLA). A third lung-protective strategy is the Stabilize Lung Approach (SLA), in which the lung is initially stabilized and gradually reopened over time. This review will analyze the physiologic efficacy and pathophysiologic potential of the above lung-protective approaches.

Serum trimethylamine N-oxide levels among coronary artery disease and acute coronary syndrome patients: a systematic review and meta-analysis.

Background and Aim: Recent studies have linked trimethylamine N-oxide (TMAO) to cardiovascular diseases; our study aimed to analyze the association between coronary artery disease (CAD), acute coronary syndrome (ACS), and TMAO. Methods: PubMed, Scopus, Embase, and Web of Science were searched using terms such as 'CAD' and 'TMAO'. Only observational controlled studies were included. RevMan software version 5.4 was used for the analysis. Results: A significant association was found between the CAD group and increased serum TMAO levels compared with the control group (MD=1.16, 95% CI=0.54-1.78, P=0.0003). This association remained significant among acute coronary syndrome patients (MD=0.98, 95% CI=0.73-1.23, P<0.00001) and was also detected among young and old CAD patients (MD=0.35, 95% CI=0.06-0.64, P=0.02 and MD=1.36, 95% CI=0.71-2.01, P<0.0001, respectively). On further analysis of intestinal metabolites, the authors detected an insignificant association between choline, betaine, carnitine, and CAD. According to our sensitivity analysis, TMAO is an acceptable diagnostic marker for CAD (0.721, SE was 0.0816, 95% CI: 0.561-0.881). Conclusion: TMAO is an acceptable diagnostic marker for CAD, with significantly higher levels among these patients regardless of their age. Other metabolites did not show such an association. The role of serum level TMAO in the early diagnosis of CAD should be further explored.

Anthracyclines and the risk of arrhythmias: A systematic review and meta-analysis.

BACKGROUND: There have been controversial findings from recent studies regarding anthracyclines use and the subsequent risk of arrhythmias. This study aimed to evaluate the existing evidence of the risk of arrhythmias in patients treated with anthracyclines. METHODS: PubMed, Scopus, and Web of Science databases were searched up to April 2022 using keywords such as "anthracycline" and "arrhythmia." Dichotomous data were presented as relative risk (RR) and confidence interval (CI), while continuous data were presented as mean difference (MD) and CI. Revman software version 5.4 was used for the analysis. RESULTS: Thirteen studies were included with a total of 26891 subjects. Pooled analysis showed that anthracyclines therapy was significantly associated with a higher risk of arrhythmia (RR: 1.58; 95% CI: 1.41-1.76; P < .00001), ST segment and T wave abnormalities (RR: 1.73, 95% CI: 1.18-2.55, P = .005), conduction abnormalities and AV block (RR = 1.86, 95% CI = 1.06-3.25, P = .03), and tachycardia (RR: 1.736, 95% CI: 1.11-2.69, P = .02). Further analyses of the associations between anthracyclines and atrial flutter (RR = 1.30, 95% CI = 0.29-5.89, P = .74), atrial ectopic beats (RR: 1.27, 95% CI: 0.78-2.05, P = .34), and ventricular ectopic beats (RR: 0.93, 95% CI: 0.53-1.65, P = .81) showed no statistically significant results. Higher doses of anthracycline were associated with a higher risk of arrhythmias (RR: 1.49; 95% CI: 1.08-2.05; P = .02) compared to the lower doses (RR: 1.36; 95% CI: 1.00-1.85; P = .05). Newer generations of Anthracycline maintained the arrhythmogenic properties of previous generations, such as Doxorubicin. CONCLUSION: Anthracyclines therapy was significantly associated with an increased risk of arrhythmias. Accordingly, Patients treated with anthracyclines should be screened for ECG abnormalities and these drugs should be avoided in patients susceptible to arrhythmia. The potential benefit of the administration of prophylactic anti-fibrotic and anti-arrhythmic drugs should also be explored.

Assessment of post-traumatic stress disorder and health-related quality of life among patients recovered from mild-to-moderate COVID-19 and their close contacts: A cross-sectional study.

The pandemic of COVID-19 is a traumatic event with distressing implications for mental health and several aspects of life. This study aimed to assess Post-traumatic Stress Disorder (PTSD) and Health-Related Quality of Life (HRQoL) among patients who experienced mild-to-moderate COVID-19 and their household contacts. This cross-sectional descriptive study was conducted between May 2020 and November 2020, in Ismailia and Suez governorates. A convenient sampling method was used. The sample size was calculated according to the prevalence of PTSD in COVID-19 patients to be 200 adult participants from both sexes, 100 patients with history of recent COVID-19 infection (up to 2 months after recovery) and their close family. COVID-19 was confirmed by a nasal swab sample tested by PCR in addition to suggestive symptoms and/or positive computed tomography lung findings. Data was collected by using the Arabic version of the Post-Traumatic Stress disorder checklist 5 (PCL5-PTSD) and the Arabic version of Health-Related Quality of Life (HRQoL). The questionnaire was collected through interviews at the Endemic and Infectious diseases and Family medicine outpatient clinics. Of the 200 studied participants, evidence of PTSD was found in 112 (56%) participants; all COVID-19 cases and 12 of their close-contact relatives. Impaired HRQoL was evident in 107 (53.5%) participants; all the COVID-19 cases and 7 contacts. The mean values total scores of the PTSD and HRQoL and its domains were significantly higher among cases compared to their contacts. The most frequently impaired domain was social (55%), psychological (54.5%), impairment (53.5%) followed by physical (48.5%) and the least was health perception (33.5%). The mean values of PTSD, HRQoL and their domains were significantly higher among participants who recalled respiratory symptoms and who had comorbid illness. The odds ratio of PTSD and HRQoL was 0.27 (95% CI: 0.2-0.36) and 0.3 (95% CI: 0.23-0.39) in participants who had more than a case of COVID-19 within their families. All the studied COVID-19 participants showed PTSD and impaired HRQoL, compared to 12% and 7% of their contacts, respectively. Past COVID-19 was associated with impairment of all domains of HRQoL and the most affected were the physical, psychological and impairment domains.

Progression of diabetic nephropathy and vitamin D serum levels: A pooled analysis of 7722 patients.

BACKGROUND AND AIM: Low serum Vitamin D levels have been associated with diabetic nephropathy (DN). Our study aimed to analyse the serum levels of vitamin D in patients suffering from DN and the subsequent changes in serum vitamin D levels as the disease progresses. METHODS: PubMed, Embase, SCOPUS and Web of Science were searched using keywords such as '25 hydroxyvitamin D' and 'diabetic nephropathy'. We included observational studies that reported the association between the serum 25 hydroxy vitamin D levels and diabetic nephropathy without restriction to age, gender, and location. R Version 4.1.2 was used to perform the meta-analysis. The continuous outcomes were represented as mean difference (MD) and standard deviation (SD) and dichotomous outcomes as risk ratios (RR) with their 95% confidence interval (CI). RESULTS: Twenty-three studies were included in our analysis with 7722 patients. Our analysis revealed that vitamin D was significantly lower in diabetic patients with nephropathy than those without nephropathy (MD: -4.32, 95% CI: 7.91-0.74, p-value = .0228). On comparing diabetic patients suffering from normoalbuminuria, microalbuminuria, or macroalbuminuria, we found a significant difference in serum vitamin D levels across different groups. Normoalbuminuria versus microalbuminuria showed a MD of -1.69 (95% CI: -2.28 to -1.10, p-value = .0002), while microalbuminuria versus macroalbuminuria showed a MD of (3.75, 95% CI: 1.43-6.06, p-value = .0058), proving that serum vitamin D levels keep declining as the disease progresses. Notwithstanding, we detected an insignificant association between Grade 4 and Grade 5 DN (MD: 2.29, 95% CI: -2.69-7.28, p-value = .1862). CONCLUSION: Serum Vitamin D levels are lower among DN patients and keep declining as the disease progresses, suggesting its potential benefit as a prognostic marker. However, on reaching the macroalbuminuria stage (Grades 4 and 5), vitamin D is no longer a discriminating factor.

The relationship between anxiety and irritable bowel syndrome symptoms among females: A cross-sectional study in Egypt.

There is a scarcity of studies focusing on irritable bowel syndrome (IBS) and anxiety in Egypt. Accordingly, our study aimed to assess the association between anxiety and IBS symptomatology among Egyptian females. Three hundred eighty-three females (145 IBS and 238 controls) were included in the study, and data were obtained using structured predesigned questionnaires. IBS and anxiety symptoms were assessed according to the Rome IV criteria and the Arabic version of the beck anxiety inventory, respectively. Both IBS and non-IBS groups showed increased anxiety during the pandemic, without a significant difference between both groups (P value = .657). Higher levels of education were significantly associated with severe anxiety (P value = .031). Multivariate analysis of IBS patients showed that intermediate education was significantly associated with 75% lower odds for increased IBS symptoms compared with illiterate or read-and-write IBS patients [odds ratio (OR): 0.25, 95% confidence interval (CI) 0.06-0.95, P value = .042]. Urban residence was significantly associated with 13.5 times greater odds of increased IBS symptoms, compared with rural residence (OR: 13.48, 95% CI 3.55-51.25, P value < .001). Moreover, patients who lost their job during the pandemic were 12.9 times more likely to have increased symptoms (OR: 12.89, 95% CI 1.84-90.15, P value = 0.01). A unit increase in patients age and beck anxiety inventory score was associated with 68% and 75% greater odds for increased IBS symptoms, respectively (OR: 1.68, 95% CI 1.12-2.53, P value = .012; OR: 1.75, 95% CI 1.08-2.84, P value = .024). Increasing anxiety is associated with increased IBS symptoms. Therefore, IBS patients should be screened for anxiety, and the role of psychiatric management of anxiety in the amelioration of IBS symptoms must be explored.

Comparison of monocyte distribution width and Procalcitonin as diagnostic markers for sepsis: Meta-analysis of diagnostic test accuracy studies.

AIM: We aimed to perform a meta-analysis to find out whether PCT and MDW could be used as accurate diagnostic markers for sepsis. METHODS: We searched PUBMED, WOS, and SCOPUS databases. Inclusion criteria were any observational or clinical trials that compared monocyte Distribution Width [MDW] with Procalcitonin [PCT] as diagnostic markers in a patient with sepsis. Case reports, editorials, conference abstracts, and animal studies were excluded. RevMan software [5.4] was used to perform the meta-analysis. RESULTS: After the complete screening, 5 observational studies were included in the meta-analysis. The total number of patients included in the meta-analysis in the sepsis group is 565 and 781 in the control group. The pooled analysis between the sepsis group and controls showed a statistically significant association between sepsis and increased levels of MDW and PCT [MD = 3.94, 95% CI = 2.53 to 5.36, p-value < 0.00001] and [MD = 9.29, 95% CI = 0.67 to 17.91, p-value = 0.03] respectively. Moreover, the subgroup analysis showed that the p-value of MDW levels [< 0.00001] is more significant than the p-value of PCT levels = 0.03, the p-value between the two subgroups [< 0.00001]. Additionally, the overall ROC Area for MDW [0.790] > the overall ROC Area for PCT [0.760]. CONCLUSION: Our study revealed a statistically significant association between sepsis and increased MDW and PCT levels compared with controls and the overall ROC Area for MDW is higher than the overall ROC Area for PCT, indicating that the diagnostic accuracy of MDW is higher than PCT.MDW can be used as a diagnostic marker for sepsis patients in the emergency department. More multicenter studies are needed to support our findings.

Guillain-Barré syndrome following COVID-19 vaccination: An updated systematic review of cases.

Key Clinical Message: Guillain-Barré syndrome (GBS) is a rare but possible complication that may occur after COVID-19 vaccination. In this systematic review, we found that GBS presented in patients with an average age of 58. The average time for symptoms to appear was 14.4 days. Health care providers should be aware of this potential complication. Abstract: Most instances of Guillain-Barré syndrome (GBS) are caused by immunological stimulation and are discovered after vaccinations for tetanus toxoid, oral polio, and swine influenza. In this systematic study, we investigated at GBS cases that were reported after receiving the COVID-19 vaccination. Based on PRISMA guidelines, we searched five databases (PubMed, Google Scholar, Ovid, Web of Science, and Scopus databases) for studies on COVID-19 vaccination and GBS on August 7, 2021. To conduct our analysis, we divided the GBS variants into two groups, acute inflammatory demyelinating polyneuropathy and non-acute inflammatory demyelinating polyneuropathy (AIDP and non-AIDP), and compared the two groups with mEGOS and other clinical presentation In this systematic review, 29 cases were included in 14 studies. Ten cases belonged to the AIDP variant, 17 were non-AIDP (one case had the MFS variant, one AMAN variant, and 15 cases had the BFP variant), and the two remaining cases were not mentioned. Following COVID-19 vaccination, GBS cases were, on average, 58 years of age. The average time it took for GBS symptoms to appear was 14.4 days. About 56 percent of the cases (56%) were classified as Brighton Level 1 or 2, which defines the highest level of diagnostic certainty for patients with GBS. This systematic review reports 29 cases of GBS following COVID-19 vaccination, particularly those following the AstraZeneca/Oxford vaccine. Further research is needed to assess all COVID-19 vaccines' side effects, including GBS.

Association of Aortic Valve Calcification and High Levels of Lipoprotein (a): Systematic Review and Meta-Analysis.

This study aimed to assess the association between aortic valve calcification and lipoprotein (a). We searched PUBMED, WOS, and SCOPUS databases. Inclusion criteria were any controlled clinical trials or observational studies that reported the level of Lipoprotein A in patients with aortic valve calcifications, excluding case reports, editorials and animal studies. RevMan software (5.4) was used to perform the meta-analysis. After complete screening, 7 studies were included with a total number of 446,179 patients included in the analysis. The pooled analysis showed a statistically significant association between the incidence of aortic valve calcium and increased levels of lipoprotein (a) compared with controls (SMD = 1.71, 95% CI = 1.04- 2.38, P-value < 0.00001). This meta-analysis showed a statistically significant association between the incidence of aortic valve calcium and increased levels of lipoprotein (a) compared with controls. Patients with high levels of lipoprotein (a) are at increased risk of developing aortic valve calcification. Medications targeting lipoprotein (a) in future clinical trials may be useful in primary prevention of aortic valve calcification in high risk patients.

Association between insomnia and the incidence of myocardial infarction: A systematic review and meta-analysis.

BACKGROUND: Insomnia has been closely associated with cardiovascular disease (CVD) including myocardial infarction (MI). Our study aims to assess the eligibility of insomnia as a potential risk factor for MI. METHODS: PubMed, Scopus, and Web of Science were searched using terms; such as "Insomnia" and "MI." Only observational controlled studies with data on the incidence of MI among insomniacs were included. Revman software version 5.4 was used for the analysis. RESULTS: Our pooled analysis showed a significant association between insomnia and the incidence of MI compared with noninsomniacs (relative risk [RR] = 1.69, 95% confidence interval [CI] = 1.41-2.02, p < .00001). Per sleep duration, we detected the highest association between ≤5 h of sleep, and MI incidence compared to 7-8 h of sleep (RR = 1.56, 95% CI = 1.41-1.73). Disorders of initiating and maintaining sleep were associated with increased MI incidence (RR = 1.13, 95% CI = 1.04-1.23, p = .003). However, subgroup analysis of nonrestorative sleep and daytime dysfunction showed an insignificant association with MI among both groups (RR = 1.06, 95% CI = 0.91-1.23, p = .46). Analysis of age, follow-up duration, sex, and comorbidities showed a significant association in insomniacs. CONCLUSION: Insomnia and ≤5 h of sleep are highly associated with increased incidence of MI; an association comparable to that of other MI risk factors and as such, it should be considered as a risk factor for MI and to be incorporated into MI prevention guidelines.

Anteriolateral versus anterior-posterior electrodes in external cardioversion of atrial fibrillation: A systematic review and meta-analysis of clinical trials.

The efficacy of anteriolateral versus anterior-posterior electrode positions in the success of atrial fibrillation's (AF) electrical cardioversion is unclear. Our aim is to perform a meta-analysis to compare the success rate of both electrode positions. PUBMED, WOS, OVID, and SCOPUS were searched. Inclusion criteria were clinical trials that compared anterior-lateral with anterior-posterior electrodes in external cardioversion of AF. After the full-text screening, 11 trials were included in the analysis. The total number of patients included in the study is 1845. The pooled analysis showed a statistically significant association between anterior-lateral electrode and increased cardioversion rate of AF (odds ratio [OR] = 1.40, 95% confidence interval [CI] = 1.02-1.92, p = .04). Subgroup analysis revealed a statistically significant association between the anterior-lateral electrode and increased cardioversion rate of AF in subgroups of less than five shocks, patients with 60 years old or more and patients with left atrial (LA) diameter >45 mm (OR = 1.72, 95% CI = 1.17-2.54, p = .006), (OR = 1.73, 95% CI = 1.18-2.54, p = .005), and (OR = 1.86, 95% CI = 1.04-3.34, p = .04), respectively. Anteriolateral electrode is more effective than anterior-posterior electrode in external cardioversion of AF, particularly in patients who have received less than 5 shocks, are 60 years old or older and have a LA diameter greater than 45 mm.

Performance of Inaugural Student Cohorts in 1-Year Special Master's Program.

SUNY Upstate Medical University (Upstate) recently revised two 1-year special master's programs (SMPs), designed to enhance academics in preparation for medical school through rigorous graduate science coursework. Upstate SMP program success was measured by graduate performance during the first year of medical school. First-year performance measures included academic deficiencies, exam performance, and participation grades in a longitudinal case-based course on ethics and public health. Upstate SMP students with MCAT scores below the 50th percentile or who self-report classified as underrepresented in medicine outperformed controls on several metrics. Upstate SMP students consistently bested controls in the longitudinal course. Overall, Upstate SMP graduates performed commensurately with classmates.
