Complex neuropsychiatric presentation of 17q12 duplication syndrome: A case report.

The chromosomal band 17q12 is characterized by a high density of genes and is bordered by segmental duplications, the structural arrangement of which increases the susceptibility of the region to deletions and duplications. Duplication of 17q12 is a rare genetic condition associated with variable characteristics from clinically asymptomatic to intellectual disabilities, seizures, and behavioral problems. The variability in phenotype is primarily due to variable expressivity and incomplete penetrance. Diagnosis is mostly established by chromosomal microarray. Treatment involves a multidisciplinary approach. We present a case of a 43-year-old female who initially presented with hyperphagia and was eventually diagnosed with bulimia nervosa, anxiety, mood disorder, and personality disorder. Additional research is required to better understand the impact of 17q12 duplication syndrome on the development of bulimia nervosa since its pathogenesis has not been adequately described in the current literature.

Diagnosing Cellulitis of the Penis with Point-of-Care Ultrasonography in a Resource-Limited Setting.

Cellulitis is a potentially serious bacterial skin infection. Penile cellulitis refers to the inflammation of the penile shaft and commonly occurs in uncircumcised, sexually active young adults. We reported the case of a 25-year-old heterosexual circumcised male patient with a two-day history of swelling and pain over the penile shaft. Local examination revealed a diffusely swollen penile shaft, erythematous, warm to the touch, and tender. The penile discharge culture was suggestive of a Streptococcus species infection. Ultrasonography of the penis showed increased echogenicity of the left side of the penile shaft soft tissue with a markedly increased Doppler signal, indicating cellulitis. Based on these findings, the patient was diagnosed with cellulitis of the penis and managed with broad-spectrum antibiotics. Though history and clinical examination are sufficient to diagnose penile cellulitis, our case highlighted that ultrasound could also support the diagnosis of penile cellulitis and help rule out differentials.

Liver injury at admission and outcomes in patients with COVID-19 disease: a prospective cohort study.

The liver is one of the common extrapulmonary organs involved in the coronavirus disease 2019 (COVID-19) infection. We aimed to find the prevalence of liver injury at hospital admission and its effects on outcomes. Methods: This is a single-center prospective observational study. All consecutive patients with COVID-19 admitted during the months of May to August 2021 were included in the study. Liver injury was defined as at least 2 times elevation of aspartate transaminase, alanine transaminase, alkaline phosphatase, and bilirubin above the upper limits on normal. The predictive efficacy of liver injury was measured as its effects on outcome variables, that is duration of hospital stay, requirement of ICU admission, mechanical ventilation, and mortality. Presence of liver injury compared with existing biomarkers markers of severe disease, that is lactate dehydrogenase, D-dimer, and C-reactive protein. Results: A total of 245 consecutive adult patients with COVID-19 infection were included in the study. Liver injury was present in 102 (41.63%) of patients. There was a significant association between the presence of liver injury and duration of hospital stay (10.74 vs. 8.9 days; P=0.013), the requirement of ICU admission (12.7 vs. 10.2%; P=0.018), mechanical ventilation (10.6% vs. 6.5%; P=0.003), and mortality (13.1% vs. 6.1%; P<0.001). Liver injury was significantly associated (P<0.001) with the corresponding elevation of serum biomarkers of severity. Conclusion: The presence of liver injury in patients with COVID-19 infection at the time of hospital admission is the independent predictor of poor outcomes and can also be used as the marker of disease severity.

Chronic Liver Disease among Patients Admitted in the Department of Internal Medicine of a Tertiary Care Centre: A Descriptive Cross-sectional Study.

Introduction: Chronic liver disease with cirrhosis is a significant cause of morbidity and mortality not only in developed but also in developing countries. Many patients already develop complications before hospital admission and require intensive medical care during hospital treatment. The main objective of the study was to find out the prevalence of the chronic liver disease among patients admitted in the Department of Internal Medicine of a tertiary care centre. Methods: A descriptive cross-sectional study was conducted among patients admitted to the Department of Internal Medicine of a tertiary care centre from 1 January 2022 to 31 March 2022. Ethical approval was obtained from the Ethical Review Board (Reference number: 2211202105). The patient admitted in the Department during the study period was included and those who do not gave consent were excluded. Convenience sampling method was used. Point estimate and 95% Confidence Interval were calculated. Results: Out of 447 patients, the prevalence of chronic liver disease was 93 (20.8%) (17.04-24.56, 95% Confidence Interval). The mean age of the patients was 49.69±10.94 years and among them, males were 64 (68.82%). Conclusions: The prevalence of the chronic liver disease among patients admitted to the Department of Internal Medicine of a tertiary care centre was lower than in other studies conducted in similar settings. Keywords: alcoholic liver diseases; liver diseases; prevalence.

Social and mental health impact of COVID-19 pandemic among health professionals of Gandaki Province, Nepal: A mixed method study.

BACKGROUND: The frontline health workers are the key players in the fight against the COVID-19 pandemic, however, several incidences of attacks, stigmatization, and discrimination towards them have been reported throughout the world during the peak of infection. The social impact experienced by health professionals can alter their efficiency and also lead to mental distress. This study aimed to examine the extent of social impact experienced by health professionals currently working in Gandaki Province, Nepal along with the factors associated with their depression status. METHODS: This was a mixed-method study where a cross-sectional online survey was executed among 418 health professionals followed by in-depth interviews with 14 health professionals of Gandaki Province. The bivariate analysis and multivariate logistic regression were performed to identify the factors associated with depression at 5% level of significance. The information collected from the in-depth interviews was clustered into themes by the researchers. RESULTS: Out of 418 health professionals, 304 (72.7%) expressed that COVID-19 has impacted their family relationships, whereas 293 (70.1%) expressed that it impacted their relationships with friends and relatives, and 282 (68.1%) expressed it impacted their relationships with community people. The prevalence of depression among health professionals was noted at 39.0%. Being a female (aOR:1.425,95% CI:1.220-2.410), job dissatisfaction (aOR:1.826, 95% CI:1.105-3.016), COVID-19 impact on family relation (aOR:2.080, 95% CI:1.081-4.002), COVID-19 impact on relationship with friends and relatives (aOR:3.765, 95% CI:1.989-7.177), being badly treated (aOR:2.169, 95% CI:1.303-3.610) and experiencing moderate (aOR:1.655, 95% CI:1.036-2.645) and severe fear (aOR:2.395, 95% CI:1.116-5.137) of COVID-19 were found to the independent predictors of depression. It was noted that the pandemic has an effect on the social relations of health professionals in multiple ways. CONCLUSION: This study noted that there is a significant impact of COVID-19 on health professionals in terms of their social and mental health aspects. The social impact experienced by health professionals is an important predictor of their mental health. The mental health and well-being of these vital workforces can be enhanced by focusing on the social aspect during the pandemic.

Progressive Cerebral Venous Thrombosis with Cranial Nerve Palsies in an Adolescent African Girl & Associated Diagnostic Pitfalls: A Rare Case Report.

Cerebral venous thrombosis (CVT) is a cerebrovascular disorder caused by complete or partial occlusion of the cerebral venous and sinus system. The etiology has been attributed to hypercoagulability and pro-thrombotic states, leading to raised intracranial pressures that often manifest as headaches and focal neurological deficits. However, the multifactorial nature of CVT can create a diagnostic conundrum for clinicians. We describe a unique case of a 16-year-old female who presented with convulsions, postictal confusion, and drowsiness followed by residual weakness of her extremities. She initially presented to the primary care center with headache, high-grade fever, and altered mental status and was empirically treated for pyogenic meningitis. The patient failed to improve with a week of antibiotics and was referred to the tertiary care center for urgent attention. On presentation, the patient developed VI and VII cranial nerve palsy. Subsequently, MRI images showed filling defects in the superior sagittal, right transverse, and sigmoid sinuses with right parietal gyral T1 hyperintensity and T2 hypo-intensity. She was diagnosed with septic CVT based on sinus venous thrombosis and venous infarction, probably secondary to meningococcal pneumonia. It can be challenging to distinguish between both conditions as their presentations overlap. Moreover, cranial nerve palsy is an infrequent manifestation of CVT, with unclear pathogenesis. We highlight the role of neuro-imaging in the early detection of CVT and bring to light the unfamiliar symptoms and a more varied clinical spectrum that may hinder the diagnosis in a limited-resource setting. Future research should be explicitly modeled to improve the diagnostic efficiency of CVT and improve outcomes in younger patient populations.

Immunomodulatory effect of different statin regimens on regulatory T-cells in patients with acute coronary syndrome: a systematic review and network meta-analysis of randomized clinical trials.

AIMS: We conducted a network meta-analysis (NMA) to determine the effects of low-dose (20 mg/day or less) conventional statin therapy (CST) and high-dose (40 mg/day or more) intensive statin therapy (IST) on the frequency of Tregs and their associated cytokines (IFN-γ, IL-10, TGF-ß) compared with control. METHODS AND RESULTS: PubMed, Cochrane Library, and EMBASE databases were searched for randomized clinical trials (RCTs) to identify relevant articles published until June 2021. We pooled data extracted from the included studies using the standardized mean difference (SMD). A random-effects model was used to conduct this NMA. Heterogeneity was evaluated using Cochran's Q test and the I2 test. The Grading of Recommendations, Assessment, Development and Evaluations (GRADE) was used to assess the quality of the study. Data analysis was conducted using R software.A total of 505 patients were enrolled in the five RCTs. NMA indicated a significant increase in Treg frequency in the CST group compared with the control group (SMD 1.77; 95% CI: 0.77-2.76; P = 0.0005) and a larger increase in the Treg frequency associated with the IST group compared with the control group (SMD 2.12; 95% CI: 1.15-3.10; P-value < 0.0001). However, there was significant heterogeneity and inconsistency among the included studies [τ2 = 0.6096; τ = 0.7808; I2 = 91.2% (80.5%; 96.0%)]. When compared with control, both CST and IST increased the levels of secreted IL-10 (SMD 2.69; 95% CI: 2.07-3.31; P-value < 0.0001 and SMD 2.14; 95% CI: 1.76-2.52; P-value < 0.0001). Compared with the control group, CST was associated with increased levels of TGF-ß (SMD 3.83; 95% CI: 0.63-7.0; P-value = 0.0189); this association was not seen in the IST group. IFN-γ levels decreased significantly in both the IST and CST groups (SMD -1.52; 95% CI: -1.94-1.10; P-value < 0.0001 and SMD -2.34; 95% CI: -2.73-1.95; P-value < 0.0001, respectively). CONCLUSION: The findings of our study indicated that both high- and low-dose statin groups increased Treg frequency compared with the control group. IST demonstrated greater benefits than CST. Furthermore, statin therapy increased IL-10 and TGF-ß levels and decreased IFN-γ levels. Overall, these results have significant implications for patients with ACS who would benefit from Treg-induced immunomodulatory balance.

Role of Inhalational Aztreonam Lysine in Lower Airway Infections in Cystic Fibrosis: An Updated Literature Review.

Cystic fibrosis (CF) is an inherited disorder most prevalent in the Caucasian population, characterized by a functional abnormality of the transmembrane conductance regulator protein that leads to a wide array of complications, including chronic lung infections. Pseudomonas aeruginosa (PA) is a frequently acquired microbe in CF patients and is associated with deterioration in pulmonary function and increased mortality. Inhaled anti-infective agents are an established curative therapy for CF airway infections, especially with chronic PA lung disease. Amongst them, aztreonam lysine for inhalation (AZLI) is an aerosolized monobactam antibiotic aztreonam, approved for use in CF patients nearly a decade ago. This literature review aims to explore studies based on the efficacy, safety, and tolerability of AZLI use in CF patients with pulmonary infections. We searched for all the relevant articles present in PubMed, Google Scholar, Cochrane Library, EMBASE, ClinicalTrials.gov, and Journal of Cystic Fibrosis for our data collection from 2000 to 2020. The use of AZLI has substantially improved lung function, respiratory symptoms, and remarkably reduced sputum PA density in CF patients, thereby improving the patient's overall quality of life. The adverse effects reported were compatible with CF lung disease. Hence, inhalational therapy with AZLI is highly efficacious and safe in the management of chronic airway infections. More clinical trials need to be conducted in the future to assess its long-term clinical benefits and adverse events as well as to explore the role of AZLI in the setting of acute lung infections.

Management of scleroderma renal crisis with left ventricular diastolic dysfunction in a resource-limited setting: A rare case report.

Scleroderma renal crisis with left ventricular diastolic dysfunction can lead to significant mortality. We presented the case of a 32-year-old female with anuria for 2 days. On further inquiry, she had joint pain, difficulty turning her head sidewise, and associated difficulty in finger movement. Also, hyperpigmentation with superimposed hypopigmentation was reported, which reduced during her pregnancy and worsened post-partum. Her family history suggested similar complaints in her mother. In addition, she had a blurring of vision. She had hypertension, microangiopathic hemolytic anemia, deranged renal function, and retinopathy on ophthalmologic examination. Radiological investigations revealed pulmonary edema, pleural effusion, and left ventricular diastolic dysfunction. Hence, a diagnosis of scleroderma renal crisis complicated by left ventricular diastolic dysfunction was made. She was managed conservatively using anti-hypertensive medications and hemodialysis, which resulted in gradual improvement. Our case highlighted the management approach to this rare presentation with anti-hypertensives and hemodialysis in a resource-limited setting.

Managing Chronic Neuropathic Pain: Recent Advances and New Challenges.

Aim: Neuropathic pain affects 7-10% of the population, with most of the patients receiving inadequate and incomplete treatment. Owing to the high financial burden and the poor quality of life of the patients and their caretakers, there is a dire need to address the challenges in diagnosing and treating chronic neuropathic pain. Methods: This literature review was conducted to review novel treatments and related challenges through a systematic search from sources such as PubMed, Google Scholar with the combination of MESH words such as neuropathic pain, management of neuropathic pain. Articles from non-English literature, reports without human subjects, animal studies, and abstracts/posters were excluded. However, human studies and studies published in English were included. Result: This review article discusses novel treatment modalities while acknowledging the challenges medical workers face while encountering neuropathic pain. Despite the recent advances in diagnosis and treatment modalities, several challenges still exist. Hence, there is still a need to explore the various treatment modalities, emphasizing the cause and underlying pathophysiology of neuropathic pain. Conclusion: We recommend integrated multimodal treatment with the current treatment facility, including various medical disciplines. However, a personalized approach would work the best depending on the 'patient's medical history. Therefore, this article recommends an integrated, cause-specific, cost-effective approach to address this problem of chronic neuropathic pain.

CT-IGFBP-4 as a Predictive Novel Biomarker of Ischemic Cardiovascular Events and Mortality: A Systematic Review.

Methods: The electronic databases PubMed, medRxiv, ScienceDirect, and Google Scholar were searched for relevant literature from inception to the 10th of December, 2021. Thus, retrieved literature was screened by title and abstract, followed by full-text screening based on the eligibility criteria. The risk of bias was accessed using the quality in prognostic studies (QUIPSs) tool. The data on cardiovascular outcomes about CT-IGFBP-4 levels were studied and the results were synthesized. Results: Five studies with a total of 1,417 participants were included in our study. The studies reported a low risk of bias. The mean age of the participants was 66.14 and more than 65% were males. Elevated CT-IGFBP-4 levels were associated with poor cardiovascular outcomes and increased mortality in severely ill patients. In contrast, there were no significant findings in the case of stable patients. Sandwich ELISA using lithium-heparin plasma provided a better detection limit of 0.15 ng/ml, low cross-reactivity (<2%), and generated linear results between 12 and 500 ng/ml. Conclusion: CT-IGFBP-4 is an efficient biomarker for the prediction of MACE and mortality in patients with severe ischemic cardiovascular events.

Post-COVID syndrome: A prospective study in a tertiary hospital of Nepal.

INTRODUCTION: The post-coronavirus disease 2019 (COVID-19) syndrome is defined as the persistence of symptoms after viral clearance and the emergence of new symptoms after a few months following recovery from COVID-19. This study aimed to assess the prevalence of post-COVID-19 syndrome and the risk factors that contribute to its development. METHODS: This study was conducted prospectively in Tribhuvan University Teaching Hospital (TUTH), located in Maharajgunj, Kathmandu. The patients were followed up for three months. RESULTS: The post-COVID status of 300 patients admitted to the COVID emergency of TUTH was studied. The mean age of the patients was 46.6±15.7 years, and the proportion of male (56%) was slightly higher than female (44%). Most of the patients (81.7%) had fever on their presentation to the emergency which was followed by fatigue (81.3%) and cough (78.3%). During the post-COVID phase, fatigue was the most common persistent symptom, with 34% experiencing fatigue after 60 days and 28.3% even after 90 days from the onset of symptoms. Univariate logistic regression showed sore throat (OR 4.6; 95% CI (2.8-7.6)), rhinitis (OR 3.6; 95% CI (2.1-5.9)), fatigue (OR 3.7; 95% CI (1.8-7.6)), diarrhea (OR 4.1; 95% CI (2.4-6.9)), anosmia (OR 6.7; 95% CI (3.9-11.3)), ageusia (OR 7.8; 95% CI (4.5-13.4)) and shortness of breath (OR 14.9; 95% CI (1.8-119.6)) at admission were all predictors of post-COVID syndrome after three months. CONCLUSION: Even after recovering from COVID-19, people with COVID-19 may develop symptoms. As a result, COVID-19's long-term consequences should not be neglected, as they may lead to increased morbidity among patients, consumption of financial resources, and added burden on the health system.

Esophageal Actinomycosis in an Immunocompetent Patient Mimicking Carcinoma: A Case Report.

Esophageal actinomycosis is a rare occurrence that presents a diagnostic challenge due to its vague clinical picture. The common symptoms include dysphagia, odynophagia and epigastric pain. These symptoms, although alarming, are usually non-specific. In this report, we describe an immunocompetent 38-year-old woman who presented with dysphagia and burning chest pain. Her initial examination and investigations suggested carcinoma of the oesophagus. On further evaluation and histopathology examination, she was diagnosed with esophageal actinomycosis and managed with antibiotics and symptomatic relief. She had significant improvement on follow up examination. The diagnosis of this condition in an immunocompetent patient can be confusing and requires a high degree of suspicion. Keywords: actinomycosis; carcinoma; case reports; esophagus.

Bell's palsy as a possible complication of mRNA-1273 (Moderna) vaccine against COVID-19.

Introduction: Vero Cell, AstraZeneca, Janssen, mRNA-1273 (Moderna), and Pfizer COVID-19 vaccines have been authorized for emergency use in Nepal. These vacines have been linked to some adverse effects, including fever, myalgia, and headache. Furthermore Bell's Palsy a rare adverse effect was also reported to be associated with the use of mRNA-1273 (Moderna) vaccine in some patients. Case presentation: In this case report we present a 17-year-old female who acquired Bell's Palsy following the administration of mRNA-1273 (Moderna) COVID-19 vaccination. Discussion: The possible etiology of BP that has been suggested is infection by reactivated viruses, such as the varicella-zoster virus (VZV), herpes simplex virus type 1 (HSV-1), human herpesvirus 6, and the Usutu virus, [1] the most accepted hypothesis is the one with reactivation of latent Herpes Simplex Virus type 1 in the geniculate ganglia of the facial nerves, an autoimmune mechanism through the mimicry of host molecules by the antigens of the vaccines. Conclusion: Though the extent of association between the mRNA vaccination and the development of Bell's Palsy has yet to be confirmed, this example highlights the need to closely monitor side effects and repercussions after receiving a new vaccine.

Cardiac Implications of COVID-19 in Deceased and Recovered Patients: A Systematic Review.

Background: Patients infected with coronavirus disease 2019 (COVID-19) present with various clinical presentations with majority of them developing pulmonary complications. This study focuses on cardiac implications of COVID-19 which are less discussed and thus will help to address cardiac implications of COVID-19. Methods: PubMed, PubMed Central, and Google Scholar were screened for articles which mentioned cardiac implications of COVID-19. NHLBI Study Quality Assessment Tools for the observational cohort and cross-sectional studies was used for assessing the risk of bias of our studies. Results: All 14 studies selected were good and had score of ≥9 by NHLBI Study Quality Assessment Tools. Cardiac complications of COVID-19 are common. They are associated with significant mortality. Also, people infected with COVID-19 with premorbid conditions such as cardiovascular diseases and diabetes mellitus have poor prognosis as compared to those without premorbid conditions. Cardiac biomarkers such as highly sensitive troponin I, creatinine, and creatinine kinase-MB on admission are good prognostic markers. Conclusions: Cardiac complications such as heart failure, myocardial injury, and arrhythmias are common among patients infected with COVID-19. Elevated cardiac markers and patients with cardiac complications require utmost care and continuous cardiac monitoring.

Characteristics of COVID-19 Breakthrough Infections among Vaccinated Individuals and Associated Risk Factors: A Systematic Review.

We sought to assess breakthrough SARS-CoV-2 infections in vaccinated individuals by variant distribution and to identify the common risk associations. The PubMed, Web of Science, ProQuest, and Embase databases were searched from 2019 to 30 January 2022. The outcome of interest was breakthrough infections (BTIs) in individuals who had completed a primary COVID-19 vaccination series. Thirty-three papers were included in the review. BTIs were more common among variants of concern (VOC) of which Delta accounted for the largest number of BTIs (96%), followed by Alpha (0.94%). In addition, 90% of patients with BTIs recovered, 11.6% were hospitalized with mechanical ventilation, and 0.6% resulted in mortality. BTIs were more common in healthcare workers (HCWs) and immunodeficient individuals with a small percentage found in fully vaccinated healthy individuals. VOC mutations were the primary cause of BTIs. Continued mitigation approaches (e.g., wearing masks and social distancing) are warranted even in fully vaccinated individuals to prevent transmission. Further studies utilizing genomic surveillance and heterologous vaccine regimens to boost the immune response are needed to better understand and control BTIs.

The Past, Present and Future of COVID-19 Associated Mucormycosis: A Rapid Review.

Coronavirus disease 2019 (COVID-19) is caused by SARS-CoV-2, which is known for the multiple mutations and forms that have rapidly spread across the world. With the imminent challenges faced by low- and middle-income countries in curbing the public health fallbacks due to limited resources, mucormycosis emerged as a fungal infection associated with high mortality. In this rapid review, we explored MEDLINE, Cochrane, Web of Science, WHO Global Database, and the search engine-Google Scholar for articles listed until July 2021 and presented a narrative synthesis of findings from 39 articles. The epidemiology, causative factors, incidence parameters, pharmacological treatment, and recommendations for low- and middle-income countries are enlisted. This study concludes that a majority of the globally reported COVID-19 associated mucormycosis cases stemmed from India. Individuals receiving systemic corticosteroids or who have a history of diabetes mellitus are more prone to contracting the disease. Public health authorities in LMIC are recommended to strengthen antifungal therapies for COVID-19 associated mucormycosis and to strategize reduction in diabetes mellitus prevalence.

Adsorption and removal of crystal violet dye from aqueous solution by modified rice husk.

An approach to removing crystal violet (CV) dye from aqueous solutions was investigated by introducing a xanthate group on charred rice husk. The newly prepared charred rice husk (CRH) and xanthated rice husk (XRH) were characterized by XRD, SEM, FTIR, and elemental analysis. A batch technique was used to adsorb CV dye in aqueous suspensions. Different adsorbent quantities, concentrations, pH, and contact times were investigated to find the effect of these parameters. The optimum pH for both CRH and XRH was found to be 10. The adsorption capacity of CV dye onto CRH and XRH was found to be 62.85 mg/g and 90.02 mg/g at pH10, respectively. Langmuir isotherms could be reasonably explained by the experimental data. Within 60 min, equilibrium was achieved. Similarly, the kinetic data are best suited to the pseudo-second-order model. In comparison to XRH with CRH, XRH was found more efficient and can be used as a feasible alternative for removing CV dye from aqueous solutions.

Cardioprotective Role of Estrogen in Takotsubo Cardiomyopathy.

Takotsubo cardiomyopathy (TC) is a rare, reversible cause of left ventricular wall motion abnormality (LVWMA) that mimics the presentation of acute myocardial infarction (AMI). TC is usually preceded by an emotional or physical stressor and appears to be more common in postmenopausal women. Various pathophysiological hypotheses of TC have been proposed, but the exact mechanism of action remains elusive. Elevated levels of catecholamines leading to cardiac dysfunction are the most prevalent hypothesis. The protective role of estrogen in the development of cardiomyopathies has been studied extensively. International Takotsubo Diagnostic Criteria (InterTAK) and Mayo clinic diagnostic criteria both have the stipulation stating prevalence of TC is higher in postmenopausal women which hints towards the protective role of estrogen in the development of TC. To review the protective role of estrogen in the mechanism of this novel pathology, we searched Pubmed and Google scholar for the relevant articles by using keywords such as: "takotsubo cardiomyopathy", "apical ballooning", "broken heart syndrome", "stress cardiomyopathy", "left ventricle wall motion abnormality", "estrogen", "estradiol" and "sex hormones". Our research revealed that although the prevalence of TC is greater in postmenopausal women as compared to men, the prognosis is worse in men. It also revealed the involvement of multiple cellular pathways under the influence of estrogen that could explain the cardioprotective effect of estrogen. Most of the articles found were based on animal studies, thus, there is an emphasis on future human studies. However, we strongly suggest evaluating estrogen levels as part of the initial workup for any patient presenting with signs and symptoms of cardiac pathology.

Usefulness of Electoral Models for COVID-19 Vaccine Distribution.

Purpose of Review: In response to the COVID-19 pandemic, there has been a remarkably accelerated development of vaccines worldwide. However, an effective distribution system is crucial for vaccination at a national level. Ecuador was one of the first Latin American countries to be most severely affected by the pandemic. It has been struggling to expand its vaccination drive and requires a strategy that provides an achievable vaccination rate and maintains its primary care services. This study aims to provide an efficient vaccination model to achieve herd immunity by utilizing the country's existing infrastructure (the centralized electoral system) for mass vaccination. Recent Findings: The national electoral data from 2017 and 2021 were used to create estimates for the proposed vaccination model. Two model variations, total personnel, needed, and the number of days needed to vaccinate 50%, 75%, and 100% of the population were considered. The numbers of vaccines needed, and vaccination sites were estimated based on the current number of registered voters and polling stations. The results from the proposed model show that 17,892,353 people can be vaccinated, at 40,093 polling stations, by 90,209 personnel if one vaccinator was available per polling station. Summary: Based on this model, even a conservative estimate shows that 12.56 days are needed to achieve herd immunity, and 16.74 days are needed to vaccinate the entire population of Ecuador. Additionally, we propose that this vaccination model can be used as a blueprint for any country to address similar catastrophes in the future.
