A Literature Review on Cochlear Implant Activation: From Weeks to Hours.

Objectives: The present literature review discusses the chronological evolution of Cochlear Implant (CI) activation and its definition among the relevant studies in the literature. In addition, the benefits of standardizing the early activation process in implantation centers worldwide are discussed. Methods: A comprehensive literature search was conducted in the major databases such as PubMed, Scopus, and Embase to retrieve all the relevant articles that reported early activation approaches following CI. Results: The evolution of the timing of early activation after CI has been remarkable in the past few years. Some studies reported the feasibility of early activation 1 day after the CI surgery in their users. Conclusions: Within the last decade, some studies have been published to report the feasibility and outcomes of its early activation. However, the process of early activation was not adequately defined, and no apparent guidelines could be found in the literature.

Colorectal cancer in patients with SARS-CoV-2: a systematic review and meta-analysis.

BACKGROUND: Patients with colorectal cancer (CRC) are more likely to develop severe course of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and experience increased risk of mortality compared to SARS-CoV-2 patients without CRC. OBJECTIVES: To estimate the prevalence of SARS-CoV-2 infection in CRC patients and analyse the demographic parameters, clinical characteristics and treatment outcomes in CRC patients with COVID-19 illness. METHODS: For this systematic review and meta-analysis, we searched Proquest, Medline, Embase, Pubmed, CINAHL, Wiley online library, Scopus and Nature for studies on the incidence of SARS-CoV-2 infection in CRC patients, published from December 1, 2019 to December 31, 2021, with English language restriction. Effect sizes of prevalence were pooled with 95% confidence intervals (CIs). Sub-group analyses were performed to minimize heterogeneity. Binary logistic regression model was used to explore the effect of various demographic and clinical characteristics on patient's final treatment outcome (survival or death). RESULTS: Of the 472 papers that were identified, 69 articles were included in the systematic review and meta-analysis (41 cohort, 16 case-report, 9 case-series, 2 cross-sectional, and 1 case-control studies). Studies involving 3362 CRC patients with confirmed SARS-CoV-2 (all patients were adults) were analyzed. The overall pooled proportions of CRC patients who had laboratory-confirmed community-acquired and hospital-acquired SARS-CoV-2 infections were 8.1% (95% CI 6.1 to 10.1, n = 1308, 24 studies, I2 98%, p = 0.66), and 1.5% (95% CI 1.1 to 1.9, n = 472, 27 studies, I2 94%, p < 0.01). The median patient age ranged from 51.6 years to 80 years across studies. The majority of the patients were male (n = 2243, 66.7%) and belonged to White (Caucasian) (n = 262, 7.8%), Hispanic (n = 156, 4.6%) and Asian (n = 153, 4.4%) ethnicity. The main source of SARS-CoV-2 infection in CRC patients was community-acquired (n = 2882, 85.7%; p = 0.014). Most of those SARS-CoV-2 patients had stage III CRC (n = 725, 21.6%; p = 0.036) and were treated mainly with surgical resections (n = 304, 9%) and chemotherapies (n = 187, 5.6%), p = 0.008. The odd ratios of death were significantly high in patients with old age (≥ 60 years) (OR 1.96, 95% CI 0.94-0.96; p < 0.001), male gender (OR 1.44, 95% CI 0.41-0.47; p < 0.001) CRC stage III (OR 1.54, 95% CI 0.02-1.05; p = 0.041), CRC stage IV (OR 1.69, 95% CI 0.17-1.2; p = 0.009), recent active treatment with chemotherapies (OR 1.35, 95% CI 0.5-0.66; p = 0.023) or surgical resections (OR 1.4, 95% CI 0.8-0.73; p = 0.016) and admission to ICU (OR 1.88, 95% CI 0.85-1.12; p < 0.001) compared to those who survived. CONCLUSION: SARS-CoV-2 infection in CRC patient is not uncommon and results in a mortality rate of 26.2%. Key determinants that lead to increased mortality in CRC patients infected with COVID-19 include older age (≥ 60 years old); male gender; Asian and Hispanic ethnicity; if SARS-CoV-2 was acquired from hospital source; advanced CRC (stage III and IV); if patient received chemotherapies or surgical treatment; and if patient was admitted to ICU, ventilated or experienced ARDS.

Performance of Children With Johanson-Blizzard Syndrome After Cochlear Implantation.

Johanson-Blizzard syndrome (JBS) is a rare autosomal recessive hereditary disorder characterized by multi-system involvement and facial dysmorphic features. One of the most common symptoms in JBS patients is bilateral severe to profound sensorineural hearing loss. The objective of this report is to highlight the performance of those patients after receiving cochlear implants (CI) as a management for their hearing loss. In this study, we reviewed the medical records of one female child diagnosed with JBS before and after cochlear implantation, with a particular focus on their auditory and language performance. After receiving the cochlear implant, our patient showed substantial improvement in her hearing threshold and communication abilities when compared to the preoperative condition. In conclusion, although cochlear implantation is considered a good approach for the management of JBS patients, the development of spoken language is not always achieved.

Clinical features and prognostic factors of intensive and non-intensive 1014 COVID-19 patients: an experience cohort from Alahsa, Saudi Arabia.

BACKGROUND: COVID-19 is a worldwide pandemic and has placed significant demand for acute and critical care services on hospitals in many countries. OBJECTIVES: To determine the predictors of severe COVID-19 disease requiring admission to an ICU by comparing patients who were ICU admitted to non-ICU groups. METHODS: A cohort study was conducted for the laboratory-confirmed COVID-19 patients who were admitted to six Saudi Ministry of Health's hospitals in Alahsa, between March 1, 2020, and July 30, 2020, by reviewing patient's medical records retrospectively. RESULTS: This cohort included 1014 patients with an overall mean age of 47.2 ± 19.3 years and 582 (57%) were males. A total of 205 (20%) of the hospitalized patients were admitted to the ICU. Hypertension, diabetes and obesity were the most common comorbidities in all study patients (27.2, 19.9, and 9%, respectively). The most prevalent symptoms were cough (47.7%), shortness of breath (35.7%) and fever (34.3%). Compared with non-ICU group, ICU patients had older age (p ≤ 0.0005) and comprised a higher proportion of the current smokers and had higher respiratory rates (p ≤ 0.0005), and more percentage of body temperatures in the range of 37.3-38.0 °C (p ≥ 0.0005); and had more comorbidities including diabetes (p ≤ 0.0005), hypertension (p ≥ 0.0005), obesity (p = 0.048), and sickle cell disease (p = 0.039). There were significant differences between the non-ICU and ICU groups for fever, shortness of breath, cough, fatigue, vomiting, dizziness; elevated white blood cells, neutrophils, alanine aminotransferase and alkaline aminotransferase, lactate dehydrogenase, and ferritin, and decreased hemoglobin; and proportion of abnormal bilateral chest CT images (p < 0.05). Significant differences were also found for multiple treatments (p < 0.05). ICU patients group had a much higher mortality rate than those with non-ICU admission (p ≤ 0.0005). CONCLUSION: Identifying key clinical characteristics of COVID-19 that predict ICU admission and high mortality can be useful for frontline healthcare providers in making the right clinical decision under time-sensitive and resource-constricted environment.

Brunner's glands hamartoma with pylorus obstruction: a case report and review of literature.

Proliferative lesions of the Brunner's glands are uncommonly encountered lesions of the small intestine, originating from the deeply seated mucosal and submucosal Brunner's glands, mainly in the duodenum. The vast majorities of these lesions are benign and include Brunner's glands hyperplasia (adenomas/nodules) and hamartomas. The etiology and pathogenesis of these lesions are not fully understood, and the diagnosis can sometimes be challenging. We report a case of Brunner's gland hamartoma in a 57-year-old man who presented with chronic dyspepsia, hematemesis and weight loss. Endoscopic and radiological investigations show a submucosal polypoid lesion at the first part of the duodenum. Routine endoscopic biopsies demonstrated normal duodenal mucosa. The lesion considered endoscopically unresectable and was surgically resected. Frozen section examination and intraoperative consultation showed unremarkable duodenal mucosa and histologically bland Brunner's glands.
