Cryoballoon ablation for atrial fibrillation in patients with heart failure and reduced left ventricular ejection fraction: A systematic review and meta-analysis.

The coexistence of atrial fibrillation (AF) with heart failure (HF) is prevalent, leading to severe complications. This review aimed to investigate the success rate and efficacy of cryoballoon ablation (CBA) by measuring the improvement in the New York Heart Association (NYHA) classification and the effect on the left ventricular systolic function in patients with AF accompanied by heart failure with reduced ejection fraction (HFrEF). Electronic databases search included PubMed, Web of Science, and Scopus in January 2023. Outcomes addressed the following: left ventricular ejection fraction (LVEF) improvement, AF recurrence, NYHA classification improvement, and mortality. STATA 17.0 software was used for data analysis. The effect size for the studies was a standard mean difference (SMD) with a 95% confidence interval (CI) for outcomes. Proportion analysis with 95% CI was used for freedom from early AF and AF after 2 years and all-cause death. We included six studies, including 1699 HF patients with 365 HFrEF patients. The SMD of postoperative LVEF compared to preoperative LVEF in HFrEF was 0.99 ([95% CI: 0.60, 1.39], p = .00), and for NYHA was -1.12 ([95% CI: -1.36, -0.87], p = .00). The analysis results in HFrEF patients for freedom from AF after 1 year was 65% ([95% CI: 0.55, 0.75], and after 2 years was 39% ([95% CI: 0.10, 0.67]). Proportional analysis was conducted for all-cause death, resulting in 3% mortality ([95% CI: -0.01, 0.07]). Cryoablation of AF accompanied by HFrEF appeared safe as it reduced AF recurrence and enhanced clinical outcomes.

Prevalence of latent tuberculosis infection in Asian nations: A systematic review and meta-analysis.

BACKGROUND: Tuberculosis (TB) is a serious public health concern around the world including Asia. TB burden is high in Asian countries and significant population harbor latent tuberculosis infection(LTBI). AIM: This systematic review and meta-analysis aims to evaluate the prevalence of LTBI in Asian countries. METHOD: We performed a systematic literature search on PubMed, Embase, and ScienceDirect to identify relevant articles published between January 1, 2005, and January 1, 2023 investigating the overall prevalence of latent TB among people of Asia. Subgroup analysis was done for Asian subregions during the study period of 2011 to 2016 and 2017 to 2023, for tuberculin skin test (TST) and interferon gamma release assay (IGRA), respectively, as well as for QuantiFERON-TB (QFT) and TSPOT TB tests. Der Simonian and Laird's random-effects model was used to pool the prevalence of LTBI found using TST and IGRA. RESULT: A total of 15 studies were included after a systematic search from standard electronic databases. The analysis showed that the prevalence of latent TB in Asia was 21% (95% confidence interval [CI]: 19%-23%) and 36% (95% CI: 12%-59%) according to IGRAs and TSTs (cut off 10 mm) results, respectively. Based on IGRA, the prevalence of latent TB was 20% (95% CI: 13%-25%) in 2011 to 2016 and 21% (95% CI: 18%-24%) in 2017 to 2023. Using QFT, the prevalence was 19% (95% CI: 17%-22%) and using TSPOT, the prevalence was 26% (95% CI: 21%-31%). According to the United Nations division of Asia, the prevalence was higher for the Southern region and least for the Western region using TST and higher in the South-Eastern region and least in the Western region using the IGRA test. CONCLUSION: Almost a quarter of the Asian population has LTBI. Its diagnosis often poses a diagnostic challenge due to the unavailability of standard test in certain areas. Given this prevalence, a mass screening program is suggested with the available standard test and public awareness along with anti-TB regimen should be considered for individuals who test positive. However, for it to be implemented effectively, we need to take the affordability, availability, and cost-effectiveness of such interventions into account.

Liver injury: the therapeutic dilemma of homeopathy - a case report from Bangladesh.

Despite the lack of scientific evidence supporting its effectiveness, homeopathic treatment is increasingly being used as a form of alternative medicine, with many people taking homeopathic remedies instead of drug therapies. It is based on the principle of 'like cures like', meaning that a remedy similar to the illness can be used to treat it. However, there have been several reports suggesting the risks of homeopathic remedies, among which homeopathy-induced liver injury is widely discussed. Here, we report a case of a 35-year-old well-oriented male patient with a typical clinical presentation of liver injury as presented by yellowish discoloration of sclera and skin along with generalized body itching following the use of homeopathic medicine for musculoskeletal pain. Laboratory reports of increased liver markers along with bilirubin were also suggestive. Excluding other differentials like viral hepatitis, alcoholic hepatitis, hemochromatosis, Wilson disease, and standard drug and toxin-induced hepatitis, the recent use of homeopathic remedies was a contributing factor in leading to the diagnosis of homeopathy-induced liver injury. He was then treated with the discontinuation of homeopathic medicine and supportive care. This case highlights the need for public awareness of the possible complications such as headache, tiredness, skin eruption, dizziness, bowel dysfunction, allergic reactions to acute pancreatitis, renal failure, neurological dysfunction, possible liver injury, and even mortality in those patients who pursue homeopathic treatments and health care professionals should take this into account when making a differential diagnosis in patients with liver injury.

Exploring the possible therapeutic role of influenza vaccine in chronic kidney disease patients.

Chronic kidney disease (CKD) is an irreversible change in kidney function and structure with a prevalence of about 9.1% worldwide. Toxins and heavy metal exposure, as well as hypertension and diabetes mellitus, are common causes of CKD. Despite extensive therapeutic options such as renal replacement therapy and renal transplants, most changes in kidney function remain irreversible, causing lifelong morbidity and affecting the quality of life of patients. Increased susceptibility to infections as well as serious complications from influenza, is a major cause of concern in nephrological care. Therefore, it is imperative to consider the protective role of influenza vaccination against seasonal influenza, which can worsen preexisting kidney dysfunction. This commentary explores a possible relationship between the influenza vaccine and patient outcomes in CKD in terms of complications, hospitalization, and possibly prognostic improvements in patient outcomes from CKD.

'Man-in-the-barrel' syndrome: a case report of bilateral arm paresis following cardiac arrest.

'Man-in-the-barrel syndrome' (MIBS) is a neurological phenotype with brachial diplegia, normal sensation, and preserved motor function of the lower limb. Severe hypotension leading to watershed infarctions leading to this phenotype has been reported. The pathogenesis of MIBS is believed to be cerebral hypoperfusion leading to border zone infarctions between the territories of the anterior and middle cerebral arteries. Case Report and Discussion: A 49-year-old chronic alcoholic hypertensive Indian male was evaluated for barrel syndrome after a cardiac arrest. MRI confirmed hyperintensities between the territories of the anterior and middle cerebral arteries bilaterally. Conclusion: Person in barrel syndrome is a rare neurological syndrome. MIB is common after cerebral hypoperfusion and carries a poor prognosis. Identification of the underlying cause is important because the management and prognosis vary based on the etiology.

Acute disseminated encephalomyelitis following the COVID-19 Vaccine Sinopharm in low- and middle-income country: a case report.

Introduction and importance: Coronavirus disease 2019 (COVID-19) is a disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and various vaccines against it have been developed. Acute disseminated encephalomyelitis (ADEM) is a disease of the central nervous system that cause inflammation and demyelination and manifests as a multi-symptom acute neurological condition. Although infections are usually the cause of ADEM, vaccines may cause 5-10% of cases. Case presentation: A 40-year-old woman had received a second dose of the Sinopharm COVID-19 vaccine 4 months before her visit and experienced sudden gait imbalance and vertigo a day after her vaccination, which lasted for more than a month. On examination, no signs of skin bruising or bleeding were observed, and her vital signs were within the normal range. On neurological assessment, the patient had a Glasgow Coma Scale score of 14/15 (E4V5M5), had normal pupil size and light reaction, normal fundus, normal deep tendon reflexes and bilateral extensor plantar response. Meningeal symptoms were absent, and SARS-CoV-2 RNA tests using NAAT (Nucleic Acid Amplification Test) were negative. Development of central nervous system (CNS) manifestations during the recovery phase of fever, along with typical MRI findings; the diagnosis of para-infectious ADEM with COVID-19 vaccination was made. After the treatment with methylprednisolone sodium succinate injection, the patient showed improvement. Clinical discussion: ADEM associated with post-vaccinations is a rare condition. There has been growing evidence that shared epitopes between neuronal proteins and SARS-CoV-2 antigens may trigger autoimmune reactions against the CNS through molecular mimicry as its pathogenesis. Conclusion: We suggest the need for a strict vaccine safety monitoring system and post-vaccine monitoring and surveillance.

Procedural safety of transcatheter aortic valve replacement with Portico valve: a systematic review.

BACKGROUND: The Portico transcatheter aortic heart valve is a self-expandable, fully resheathable bioprosthetic valve with a nitinol frame and porcine pericardial sealing cuff. It has been used among symptomatic severe aortic stenosis (AS) who are at high or extreme surgical risk. However, till date very few studies has been reported with inconclusive evidence for its postprocedure safety outcomes. OBJECTIVE: The authors aim to evaluate the safety of the Portico transcatheter aortic valve replacement system among patients with AS. METHODOLOGY: The authors conducted a systematic literature search on PubMed, Embase, and Scopus from inception till 10th April 2023 by using predefined MESH terms using 'AND' and 'OR'. The following search terms were used: 'Aortic Stenosis' AND 'Transcatheter aortic valve replacement' OR 'Portico valve'. Finally, descriptive statistics were used to summarize the data in this paper. The mean and SD were adopted to describe continuous variables, whereas frequencies and percentages were used for dichotomous data. RESULTS: A total of 7 studies with 2782 patients were included in the analysis. The mean age of patients was 82.3 years, and 54.63% were female. The most common comorbidity was hypertension (65.21%) and diabetes mellitus (26.45%). Among patients of AS with Portico valve implants, postprocedural outcomes including 30-day mortality (2.32%), cardiovascular mortality (2.37%), stroke (2.23%), myocardial infarction (0.94%), major bleeding (3.97%), major vascular complications (4.91%), acute kidney injury (1.37%), and permanent pacemaker implantations in 15.73% patients were reported. Overall, device success was observed in 95.82% of patients. CONCLUSION: Transcatheter aortic valve replacement with the repositionable Portico valve, a new bioprosthesis, appears to have a low postprocedural mortality rate and other clinical outcomes in high-risk patients with severe AS.
