RESUMO
Aims: This study entails an association between bronchial asthma and common single nucleotide polymorphisms (SNPs) in thymic stromal lymphopoietin (TSLP) gene; rs2289278, rs3806933, rs2289276, and rs1837253. Methods: The databases of PubMed, Embase, Web of Science, and Google Scholar were searched for studies reporting TSLP polymorphisms and asthma from inception to January 2022. Hardy-Weinberg equilibriums (HWE) for each polymorphism of the control group were checked using the χ 2 test. The association was estimated by means of odds ratio (OR) with 95% CI in both dominant and recessive modes of inheritance, respectively. Results: Altogether, 11 studies with 3121 asthma cases and 3041 healthy controls were added. Results from six studies showed that the SNP rs2289278 had a protective role in asthma development (OR=0.65, 95% CI: 0.44-0.97, P=0.04). Pooling of four studies showed that the SNP rs3806933 had higher odds of developing asthma (OR=1.32, 95% CI:1.14-1.54, P<0.01). However, the SNP rs2289276 and rs1837253 showed no significant association. From the subgroup analysis, SNPs rs2289278 and rs1837253 were protective against the development of asthma in Asia. However, SNP rs2289276 showed a risk association in Asia and in adults. Conclusion: This meta-analysis shows that the SNP rs2289278 has a protective effect on the development of asthma; whereas rs3806933 has a risk of asthma. Additionally, this study adds genomic-based support to the recent FDA approval of tezepelumab, an anti-TSLP agent.
RESUMO
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.
RESUMO
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.

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.

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.
RESUMO
'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.
