Association between pre-existing conditions and hospitalization, intensive care services and mortality from COVID-19 - a cross sectional analysis of an international global health data repository

Objective: To investigate the association between pre-existing conditions and hospitalization, need for intensive care services (ICU) and mortality due to COVID-19. Methods: We used data on all cases recorded in the Global Health Data repository up to the 10th of March 2021 to carry out a cross-sectional analysis of associations between cardiovascular diseases (CVD), hypertension, diabetes, obesity, lung diseases and kidney disease and hospitalization, ICU and mortality due to COVID-19. We included data from Brazil, Mexico and Cuba only as they were the only countries where preexisting conditions were reported. We used multivariable logistic regression to compute adjusted and unadjusted odds ratios (OR) of the three outcomes for each pre-existing condition in ten-year age groups from 0-9 years and up to 110-120 years. Results: As of the 10th of March 2021, the Global Health repository held 25 900 000 records of confirmed cases of COVID-19, of which 2 900 000 cases from Brazil, Mexico and Cuba had data on preexisting conditions. The overall adjusted odds of hospitalization for each pre-existing condition were; CVD (OR 1.7, 95%CI 1.7-1.7), hypertension (OR 1.5, 95%CI 1.4-1.5), diabetes (OR 2.2, 95%CI 2.1-2.2), obesity (OR 1.7, 95%CI 1.6-1.7), kidney disease (OR 5.5, 95%CI 5.2-5.7) and lung disease (OR 1.9, 95%CI 1.8-1.9). The overall adjusted odds of ICU for each pre-existing condition were; CVD (OR 2.1, 95%CI 1.8-2.4), hypertension (OR 1.3, 95%CI 1.2-1.4), diabetes (OR 1.7, 95%CI 1.5-1.8), obesity (OR 2.2, 95%%CI 2.1-2.4), kidney disease (OR 1.4, 95%CI 1.2-1.7) and lung disease (OR 1.1, 95%CI 0.9-1.3). The overall adjusted odds of mortality for each pre-existing condition were; CVD (OR 1.7, 95%CI 1.6-1.7), hypertension (OR 1.3, 95%CI 1.3-1.4), diabetes (OR 2.0, 95%CI 1.9-2.0), obesity (OR 1.9, 95%CI 1.8-2.0), kidney disease (OR 2.7, 95%CI 2.6-2.9) and lung disease (OR 1.6, 95%CI 1.5-1.7). The odds of each outcome were considerably larger in children and young adults with these preexisting conditions than for adults, especially for kidney disease, CVD and diabetes. Conclusion: Individuals with CVD, hypertension, diabetes, obesity, lung diseases and kidney diseases have high odds of hospitalization, ICU and mortality from COVID-19. The odds of these outcomes are especially elevated in children and young adults with these preexisting condition

Oral Healthcare Services Delivered During COVID-19 Lockdown: A Report from Eastern Mediterranean Region

Objective: To describe oral healthcare services administered during the lockdown in the Eastern Mediterranean region and to investigate the role of socio-professional characteristics of dental practitioners or their self-reported COVID-19 infection. Material and Methods: A questionnaire was distributed to dental practitioners in all healthcare sectors in Jordan, Egypt, and Saudi Arabia. Results: There was a total of 335 participants, with the majority being females (N=225, 67.2%) and general practitioners (N=202, 60.3%). Cellulitis was the most common emergency encountered (N=108). The most common urgent procedures were for pulpitis, abscesses, and pericoronitis (N=191, 130, and 95, respectively). Country-specific significant associations were pulpitis in Egypt and Jordan, broken symptomatic teeth in Jordan, and biopsy in Egypt (p<0.05). The Ministry of Health was significantly associated with the management of dental infections, avulsion, and orthodontic emergencies, while university hospitals were significantly associated with advanced restorative procedures (p<0.05). Male practitioners performed significantly more procedures, particularly surgical emergencies (p<0.05). Conclusion: Dental infections were the most common complaints among dental patients during lockdown. Country- and sector-specific dental procedures are detected. Male gender seems to play a determinant role in performing a higher number of procedures, particularly for surgical emergencies

Association between Multimorbidity and COVID-19 Mortality in Qatar: A Cross-Sectional Study

This study assessed the association between multimorbidity and mortality from COVID-19 in the Middle East and North Africa region, where such data are scarce. We conducted a cross-sectional study using data of all cases with COVID-19 reported to the Ministry of Public Health of Qatar from March to September 2020. Data on pre-existing comorbidities were collected using a questionnaire and multimorbidity was defined as having at least two comorbidities. Proportions of deaths were compared by comorbidity and multimorbidity status and multivariable logistic regression analyses were carried out. A total of 92,426 participants with a mean age of 37.0 years (SD 11.0) were included. Mortality due to COVID-19 was associated with gastrointestinal diseases (aOR 3.1, 95% CI 1.16–8.30), respiratory diseases (aOR 2.9, 95% CI 1.57–5.26), neurological diseases (aOR 2.6, 95% CI 1.19–5.54), diabetes (aOR 1.8, 95% CI 1.24–2.61), and CVD (aOR 1.5, 95% CI 1.03–2.22). COVID-19 mortality was strongly associated with increasing multimorbidity; one comorbidity (aOR 2.0, 95% CI 1.28–3.12), two comorbidities (aOR 2.8, 95% CI 1.79–4.38), three comorbidities (aOR 6.0, 95% 3.34–10.86) and four or more comorbidities (aOR 4.15, 95% 1.3–12.88). This study demonstrates a strong association between COVID-19 mortality and multimorbidity in Qatar

Antimicrobial resistance among migrants in Europe: a systematic review and meta-analysis

BACKGROUND: Rates of antimicrobial resistance (AMR) are rising globally and there is concern that increased migration is contributing to the burden of antibiotic resistance in Europe. However, the effect of migration on the burden of AMR in Europe has not yet been comprehensively examined. Therefore, we did a systematic review and meta-analysis to identify and synthesise data for AMR carriage or infection in migrants to Europe to examine differences in patterns of AMR across migrant groups and in different settings. METHODS: For this systematic review and meta-analysis, we searched MEDLINE, Embase, PubMed, and Scopus with no language restrictions from Jan 1, 2000, to Jan 18, 2017, for primary data from observational studies reporting antibacterial resistance in common bacterial pathogens among migrants to 21 European Union-15 and European Economic Area countries. To be eligible for inclusion, studies had to report data on carriage or infection with laboratory-confirmed antibiotic-resistant organisms in migrant populations. We extracted data from eligible studies and assessed quality using piloted, standardised forms. We did not examine drug resistance in tuberculosis and excluded articles solely reporting on this parameter. We also excluded articles in which migrant status was determined by ethnicity, country of birth of participants' parents, or was not defined, and articles in which data were not disaggregated by migrant status. Outcomes were carriage of or infection with antibiotic-resistant organisms. We used random-effects models to calculate the pooled prevalence of each outcome. The study protocol is registered with PROSPERO, number CRD42016043681. FINDINGS: We identified 2274 articles, of which 23 observational studies reporting on antibiotic resistance in 2319 migrants were included. The pooled prevalence of any AMR carriage or AMR infection in migrants was 25·4% (95% CI 19·1-31·8; I2 =98%), including meticillin-resistant Staphylococcus aureus (7·8%, 4·8-10·7; I2 =92%) and antibiotic-resistant Gram-negative bacteria (27·2%, 17·6-36·8; I2 =94%). The pooled prevalence of any AMR carriage or infection was higher in refugees and asylum seekers (33·0%, 18·3-47·6; I2 =98%) than in other migrant groups (6·6%, 1·8-11·3; I2 =92%). The pooled prevalence of antibiotic-resistant organisms was slightly higher in high-migrant community settings (33·1%, 11·1-55·1; I2 =96%) than in migrants in hospitals (24·3%, 16·1-32·6; I2 =98%). We did not find evidence of high rates of transmission of AMR from migrant to host populations. INTERPRETATION: Migrants are exposed to conditions favouring the emergence of drug resistance during transit and in host countries in Europe. Increased antibiotic resistance among refugees and asylum seekers and in high-migrant community settings (such as refugee camps and detention facilities) highlights the need for improved living conditions, access to health care, and initiatives to facilitate detection of and appropriate high-quality treatment for antibiotic-resistant infections during transit and in host countries. Protocols for the prevention and control of infection and for antibiotic surveillance need to be integrated in all aspects of health care, which should be accessible for all migrant groups, and should target determinants of AMR before, during, and after migration.

Surgical site infection after gastrointestinal surgery in high-income, middle-income, and low-income countries: a prospective, international, multicentre cohort study

Background: Surgical site infection (SSI) is one of the most common infections associated with health care, but its importance as a global health priority is not fully understood. We quantified the burden of SSI after gastrointestinal surgery in countries in all parts of the world. Methods: This international, prospective, multicentre cohort study included consecutive patients undergoing elective or emergency gastrointestinal resection within 2-week time periods at any health-care facility in any country. Countries with participating centres were stratified into high-income, middle-income, and low-income groups according to the UN's Human Development Index (HDI). Data variables from the GlobalSurg 1 study and other studies that have been found to affect the likelihood of SSI were entered into risk adjustment models. The primary outcome measure was the 30-day SSI incidence (defined by US Centers for Disease Control and Prevention criteria for superficial and deep incisional SSI). Relationships with explanatory variables were examined using Bayesian multilevel logistic regression models. This trial is registered with ClinicalTrials.gov, number NCT02662231. Findings: Between Jan 4, 2016, and July 31, 2016, 13 265 records were submitted for analysis. 12 539 patients from 343 hospitals in 66 countries were included. 7339 (58·5%) patient were from high-HDI countries (193 hospitals in 30 countries), 3918 (31·2%) patients were from middle-HDI countries (82 hospitals in 18 countries), and 1282 (10·2%) patients were from low-HDI countries (68 hospitals in 18 countries). In total, 1538 (12·3%) patients had SSI within 30 days of surgery. The incidence of SSI varied between countries with high (691 [9·4%] of 7339 patients), middle (549 [14·0%] of 3918 patients), and low (298 [23·2%] of 1282) HDI (p < 0·001). The highest SSI incidence in each HDI group was after dirty surgery (102 [17·8%] of 574 patients in high-HDI countries; 74 [31·4%] of 236 patients in middle-HDI countries; 72 [39·8%] of 181 patients in low-HDI countries). Following risk factor adjustment, patients in low-HDI countries were at greatest risk of SSI (adjusted odds ratio 1·60, 95% credible interval 1·05–2·37; p=0·030). 132 (21·6%) of 610 patients with an SSI and a microbiology culture result had an infection that was resistant to the prophylactic antibiotic used. Resistant infections were detected in 49 (16·6%) of 295 patients in high-HDI countries, in 37 (19·8%) of 187 patients in middle-HDI countries, and in 46 (35·9%) of 128 patients in low-HDI countries (p < 0·001). Interpretation: Countries with a low HDI carry a disproportionately greater burden of SSI than countries with a middle or high HDI and might have higher rates of antibiotic resistance. In view of WHO recommendations on SSI prevention that highlight the absence of high-quality interventional research, urgent, pragmatic, randomised trials based in LMICs are needed to assess measures aiming to reduce this preventable complication

Validity of Doppler subclinical synovitis as an activity marker associated with bone erosions in rheumatoid arthritis patients during clinical remission

Introduction: Clinical remission is a realistic goal in rheumatoid arthritis (RA) patients. Doppler signals-synovitis may also be considered predictive of clinical flare-ups in RA. Objective: The aim of this study was to detect subclinical synovitis and erosions by musculoskeletal ultrasound (MSUS) in RA patients with clinical remission and free from physical synovitis. Materials and methods: 41 RA patients were studied who achieved clinical remission for at least 6 months proved by clinical disease activity index (CDAI) and DAS28 without tender neither swollen joints. MSUS of 22 joint done for each patient, the data of gray scale (GSUS) and color Doppler ultrasound (CDUS) graded on a semi-quantitative scale from 0 to 3. Results: The percentage of RA patients with subclinical synovitis present in at least one joint with CDUS ⩾ 1, and CDUS ⩾ 2 were 70.7% and 29.2% respectively. The results of CDUS were significantly lower with biologic agents compared to patients on conventional disease modifying anti-rheumatic drugs (DMARDs) alone (p = 0.01). There was a strong association between CDUS synovitis and MSUS bone erosions (p < 0.00001). Conclusion: Doppler detected subclinical synovitis could be considered a reliable marker to appraise disease activity in RA patients compared to DAS28 and CDAI, in associated joint destruction secondary to erosions

Colchicine and mortality outcomes in patients with coronavirus disease (COVID-19)

One of the therapeutic hallmarks of the ongoing (COVID-19) pandemic has been the different iterations of successful and sometimes unsuccessful attempts at re-purposing of drugs with pre-existing market authorization for use in COVID-19 patients. We therefore read with interest Perricone et al’s., recent report on the clinical outcomes of hospitalized COVID-19 patients exposed to colchicine [1]. This randomized controlled clinical trial (RCT) evaluating efficacy and safety of generic colchicine found no significant difference in the primary composite endpoints of intensive care admissions (ICU) and the need for mechanical ventilation between patients exposed to colchicine added to standard of care (N = 77) vs. controls (N = 75) stabilized on usual standard of care (mechanical ventilation 5.2% vs 4%, ICU 1.3% vs 5.3%, death 9.1% vs. 6.7%, overall 11 (14.3%) vs. 10 (13.3%) patients, P=not significant). Perricone et al’s., report has “arrived” at critical time against a backdrop of ongoing uncertainty regarding the exact relationship between colchicine exposure and hard clinical endpoints in COVID-19 patients. Discordant studies from both observational as well as clinical trials have reported both mortality-reducing propensity of colchicine in these cohorts of patients, as well null effect by others [2]

The Contemporary Role of Hematopoietic Stem Cell Transplantation in the Management of Chronic Myeloid Leukemia: Is It the Same in All Settings?

Hematopoietic stem cell transplantation (HSCT) for chronic myeloid leukemia (CML) patients has transitioned from the standard of care to a treatment option limited to those with unsatisfactory tyrosine kinase inhibitor (TKI) responses and advanced disease stages. In recent years, the threshold for undergoing HSCT has increased. Most CML patients now have life expectancies comparable to the general population, and therefore, the goal of therapy is shifting toward achieving treatment-free remission (TFR). While TKI discontinuation trials in CML show potential for achieving TFR, relapse risk is high, affirming allogeneic HSCT as the sole curative treatment. HSCT should be incorporated into treatment algorithms from the time of diagnosis and, in some patients, evaluated as soon as possible. In this review, we will look at some of the recent advances in HSCT, as well as its indication in the era of aiming for TFR in the presence of TKIs in CML
