Ventilator-associated pneumonia (VAP) is one of the most frequent ICU-acquired infections and a leading cause of death among patients in Intensive Care Unit (ICU). The South East Asian Region is a part of the world with limited health resources where infectious diseases are still underestimated. We aimed to review the literature in this part of the world to describe incidence, mortality and microbiological evidence of VAP and explore preventive and control strategies. We selected 24 peer-reviewed articles published from January 1, 2000 to September 1, 2020 from electronic databases and manual searching for observational studies among adult patients diagnosed with VAP expressed per thousand days admitted in ICU. The VAP rates ranged from 2.13 to 116 per thousand days, varying among different countries of this region. A significant rate of mortality was observed in 13 studies ranging from 16.2% to 74.1%. Gram negative organisms like Acinetobacter spp., Pseudomonas aeruginosa and Klebsiella pneumoniae and Gram-positive organisms like Staphylococcus aureus and Enterococcus species were frequently found. Our findings suggest an alarming situation of VAP among patients of most of the countries of this region with increasing incidence, mortality and antibiotic resistance. Thus, there is an urgent need for cost effective control and preventive measures like interventional studies and educational programs on staff training, hand hygiene, awareness on antibiotic resistance, implementation of antibiotic stewardship programs and appropriate use of ventilator bundle approach.
Introduction Lewy bodies are the pathological hallmarks of Parkinson's disease. There is a need for effective biomarker that is cost effective, less invasive, and easily reproducible with good sensitivity and specificity and can be used to diagnose the condition early and track its severity and progression. Alpha‐synuclein (α‐syn), an integral component of the Lewy body, is found in saliva and can be a potential answer to the above concerns. Methods PubMed, EMBASE, Google Scholar, and CNKI databases, along with additional sites, were searched from January 2010 to August 2021. Standard mean difference (Hedges' g) with 95% CI was used to show an association. Statistical analysis was done using STATA software version 16 (StataCorp). Results We found a significant reduction in the mean difference of total salivary α‐syn among PD patients compared to healthy controls. However, the mean difference of oligomeric α‐syn and oligo/total salivary α‐syn ratio was significantly increased among PD patients compared to healthy controls. Conclusion Our systematic review and meta‐analysis found that salivary α‐syn parameters (total, oligomeric, oligo/total) can be considered a simple, easy‐to‐use, cost‐effective, and reliable diagnostic biomarker for PD and its progression.
We aimed to estimate the pooled prevalence of Helicobacter pylori among asymptomatic South Asians based on available literature and highlight the importance of screening asymptomatic individuals and implementing preventive strategies for eradicating H. pylori . Electronic databases such as PubMed and Embase, a regional database of WHO South Asian Region, and gray literature sites were searched for relevant studies from 1983 to 5 May 2020. In addition, references of the included studies were thoroughly searched. The random‐effect model was used to calculate the pooled prevalence with a 95% confidence interval (CI) along with subgroup analysis. Analysis of 19 studies showed a pooled prevalence of 56.5%, ranging from 10.3 to 91.7%. In subgroup analysis by country, the highest prevalence rate was reported from Bangladesh (86.3%, 95% CI: 0.806–0.921), whereas the lowest prevalence was from Sri Lanka (10.3%, 95% CI: 0.072–0.135). No differences were found between males and females. Prevalence among children and adolescents was 65.3% (95% CI: 0.529–0.777), greater than adults, 56.9% (95% CI: 0.353–0.785). The prevalence rate showed a decreasing trend upon comparison of studies conducted before and after 2000. Our analysis reveals the high prevalence of H. pylori infection among asymptomatic healthy populations in South Asia, particularly in children and adolescents. Public health awareness and sanitation interventions, pure drinking water, and respective strategies on a policy level to eradicate H. pylori and additional extensive multicentric cohort studies are necessary.
Sickle cell anemia (SCA) is an inherited autosomal recessive disease. It is caused due to point mutation that substitutes glutamate with valine at the sixth amino acid position of the beta chain of hemoglobin molecules leading to the sickling of the red blood cells and decreased structural deformability. Silent cerebral infarcts are the most common neurological complication of SCA, while overt stroke comprises substantial burden in patients with SCA. This meta-analysis aimed to find the pooled prevalence of overt stroke in SCA patients and discuss the importance of screening them. PubMed, Embase, and Google Scholar were the electronic databases used to search the studies. A total of 765 articles were retrieved upon detailed searching in the abovementioned databases. After a series of removing duplicate articles, title and abstract screening, and full-text review, 20 articles were found eligible and included in the study. The total number of participants from all the included studies was 3,956, and pooled prevalence of stroke in patients with sickle cell anemia in Asia was found to be 5% (95% CI: 4%, 6%) with a range from 1 to 41%. Stroke occurrence in sickle cell anemia patients is an emergency complication that needs immediate intervention and management. Because of the high prevalence of stroke in patients with sickle cell anemia, clinicians should focus on its prevention and treatment strategies.
Ischemic heart disease, also known as coronary heart disease (CHD) refers to a heart condition that is characterized by narrowing of arteries, which supply blood to the heart muscles. This narrowing can cause irreversible damage or death of the cardiac muscles due to severe deprivation of blood flow to a specific area of the heart, thus called myocardial infarction. 1 Myocardial infarction is a pathological condition caused by disruption of the blood supply to a region of the heart to an extent that limits adequate oxygenation, even with an extended period of rest. 2 According to the Global Burden Disease, the burden of IHD-related deaths was 8.9 million in 2017, which is a 52.3% increase from 5.9 million in 1990, 3 and acute myocardial infarction (AMI) is the leading cause of death among ischemic heart
Introduction and importance Edward's syndrome (ES) occurs as a result of trisomy of chromosome 18 and is associated with multisystem congenital anomalies. The association of ES with various gastrointestinal malformations but Hirschsprung disease (HD) is well documented. Case presentation A female infant on her 5th day of life presented with episodes of bilious vomiting along with abdominal distension and no passage of stool. The child had a small head and prominent occiput, low set abnormal ears, small jaw, upturned nose, widely spaced eyes, small neck with widely spaced nipples, clenched hands with overlapping fingers, flexed big toe, and prominent heels. Clinical discussion Edward syndrome is associated with multisystem congenital abnormalities of which gastrointestinal abnormalities make up the most part. The condition can be identified by fetal ultrasound screening. Surgical correction of associated congenital anomalies at different times along with lifelong supportive management is important. Conclusions Edward syndrome can present as Hirschsprung disease as a part of associated gastrointestinal Malformation. Often, early identification and termination of the pregnancy in antenatal life can reduce the suffering. Surgical correction of associated anomalies along with supportive care forms the cornerstone of management. However, the prognosis remains poor.
Introduction and importance Adrenal Leiomyomas are infrequent tumors with only a few cases reported to date. They are difficult to differentiate from malignant adrenal tumors due to non-specific findings on clinical examination and imaging studies. Case presentation We discuss the case of a 49-year old male who had been experiencing generalized abdominal pain for 14 months and was found to have a mass on ultrasonography. Further evaluation with Contrast-enhanced Computerized Tomography (CECT) revealed an uneven soft tissue density mass in the retroperitoneal region of the left side. The histopathological examination of the excised mass was suggestive of a mesenchymal tumor, which was further confirmed as leiomyoma by immunohistochemistry. Clinical discussion Adrenal Leiomyomas are rare smooth muscle tumors that present with heterogeneously enhancing mass on radiologic imaging. On histopathological examination, spindle cells arranged in lobules and fascicles can be appreciated. Positive staining for desmin and smooth muscle actin in immunohistochemistry confirms the diagnosis. Conclusion Identification of the type of tumor in any adrenal mass is challenging pertaining to the non-specific findings on imaging studies. So, prompt surgical resection is the mainstay of the treatment.
The protocol entails our plan to conduct a systematic review with meta-analysis so as to inquire into patterns of variation in the surgical and oncological outcomes for primary pancreatic neuroendocrine tumours and whether the variation in the surgical techniques can explain such patterns, either completely or partially.
