Invasiveness of Treatment Is Gender Dependent in Intensive Care: Results From a Retrospective Analysis of 26,711 Cases.

Health care and outcome of critically ill patients are marked by gender-related differences. Several studies have shown that male patients in intensive care units (ICU) more often receive mechanical ventilation, dialysis, pulmonary arterial catheterization (PAC), and central venous catheterization (CVC). We investigated gender-related differences in ICU treatment and mortality. This retrospective, single-center study analyzed adult ICU patients admitted to the University Medical Center Regensburg between January 2010 and December 2017. Illness severity was measured with the Simplified Acute Physiology Score II (SAPS II) at ICU admission. We evaluated the intensity of ICU treatment according to the implementation of tracheostomy and extracorporeal membrane oxygenation (ECMO). We then assessed gender-related differences in the duration of mechanical ventilation and other invasive monitoring (PAC) and treatment methods (CVC, endotracheal intubation rate, and dialysis). ICU treatment and mortality data were obtained from an electronic data capture system. After adjusting for age, reason for hospitalization, and SAPS II score, we assessed the influence of gender on the intensity of ICU treatment using multivariable logistic regression. Odds ratios (OR) for the logistic regression models and incidence rate ratios (IRR) for the negative binomial regression models were calculated as effect estimates together with the corresponding 95% confidence intervals (95% CI). A P value of <.05 was considered significant. The study analyzed 26,711 ICU patients (64.8% men). The ICU mortality rate was 8.8%. Illness severity, ICU, and hospital mortality did not differ by gender. Women were older than men (62.6 vs 61.3 years; P < .001) at ICU admission. After multivariable adjustment, men were more likely to undergo tracheostomy (OR = 1.39 [1.26-1.54]), ECMO (OR = 1.37 [1.02-1.83]), dialysis (OR = 1.29 [1.18-1.41]), and PAC insertion (OR = 1.81 [1.40-2.33]) and had a longer duration of mechanical ventilation than women (IRR = 1.07 [1.02-1.12]). The frequency of endotracheal intubation (OR = 1.04 [0.98-1.11]) and placement of CVC (OR = 1.05 [0.98-1.11]) showed no gender-specific differences. Of ICU nonsurvivors, men were more likely to undergo tracheostomy (20.1% vs 15.3%; P = .004) and dialysis (54% vs 46.4%; P < .001) than women and had a longer duration of mechanical ventilation (6.3 vs 5.4 days; P = .015). After adjustment for severity of disease and outcome, ICU treatment differs between men and women. Men were more likely than women to undergo tracheostomy and ECMO.

Diarrhea and altered inflammatory cytokine pattern in severe coronavirus disease 2019: Impact on disease course and in-hospital mortality.

Dynamic changes of immunocyte subsets and inflammatory profiles in coronavirus disease 2019 (COVID-19) patients with gastrointestinal symptoms were undetermined. A single-center retrospective analysis of 409 severe, hospitalized COVID-19 patients from 20 January to 29 February 2020 was performed. The longitudinal characteristics of immune inflammatory cytokines in patients with/without diarrhea were analyzed. The relations of diarrhea and immuno-inflammatory factors with illness course and clinical outcomes were further explored. Diarrhea was more common and more serious with longer duration (4.9±1.5 vs 4.2±1.5days, P=0.039) and higher frequency (5.5±2.1 vs 4.0±2.0 times/day, P=0.001) in deceased patients than in the survivors. Also, diarrhea patients were more inclined to develop multi-organ damage: survivors have longer illness course (media 41.0 vs 36.0days, P=0.052) and hospital stays (media 27.0 vs 23.0days, P=0.041), and the deceased patients had higher mortality (33.0% vs 22.6%, P=0.045) and earlier death (media 20.0 vs 25.0days, P=0.038). Progressively, neutrophilia and lymphopenia, especially the declined CD8+ T cells, were demonstrated in diarrhea patients relative to the non-diarrhea cases. The inflammatory cytokines including IL-6, IL-10, and TNF-α were intensively increased in patients with diarrhea. The multivariable logistic analysis showed longer duration of diarrhea (P=0.036), higher neutrophil counts (P=0.011), and lower lymphocyte counts (P<0.001) were independent risk factors of in-hospital death. The proportional hazards model indicated that longer duration of diarrhea (P=0.002), higher frequency of diarrhea (P=0.058), higher neutrophil counts (P=0.001), lower lymphocyte counts (P=0.035), and decreased proportion of CD8+ T cells (P<0.001) were independently associated with longer illness course of the survivors. Diarrhea patients were more likely to present with neutrophilia, lymphopenia, and cytokine storm and to develop multi-organ damage. The inflammatory patterns were independent factors associated with illness course of the survivors and in-hospital death of severe COVID-19.

Seven-Year Case-Control Study in California of Risk Factors for Infant Botulism

To ascertain possible risk factors for infant botulism, the intestinal infectious form of human botulism, in the years immediately following its initial recognition in California in1976. Parents of 159 California laboratory-confirmed cases of infant botulism from 1976 to 1983 and 318 healthy controls were interviewed using a comprehensive (>300 factors) questionnaire. "Neighborhood controls" (n=184) were matched on date of birth, sex, race/ethnicity, and neighborhood of residence. "County controls" (n=134) were matched only on date of birth, sex, and county of residence. Age-stratified bivariate and multivariate conditional logistic regression analyses were performed using SAS. All cases required hospitalization. Bivariate analyses identified several risk factors that in multivariate analyses were not significant. In multivariate analyses, risk factors differed with stratification by age. For the ≤2 month-old neighborhood controls comparison, birth order >1, cesarean delivery, ≤1 bowel movements (BMs) per day, and windy residence area were associated with illness hospitalization, and for the county controls comparison, only pacifier use was associated. For the <2 month-old neighborhood controls comparison, <1 bowel movements (BMs) per day, cesarean delivery, birth order >1, and windy residence area were associated with illness hospitalization, and for the county controls comparison, pets in the home was an additional risk factor. With the exception of the ≤2-month-old county controls group, slower intestinal transit time (≤1 BM/d) was associated with illness. Otherwise, our case-control investigation identified few physiologic, environmental, and maternal factors associated with infant botulism hospitalization in California.

Airway Clearance Techniques in Bronchiectasis: Analysis From the United States Bronchiectasis and Non-TB Mycobacteria Research Registry

In patients with bronchiectasis, airway clearance techniques (ACTs) are important management strategies. What are the differences in patients with bronchiectasis and a productive cough who used ACTs and those who did not? What was the assessment of bronchiectasis exacerbation frequency and change in pulmonary function at 1-year follow up? Adult patients with bronchiectasis and a productive cough in the United States Bronchiectasis and NTM Research Registry were included in the analyses. ACTs included the use of instrumental devices and manual techniques. Stratified analyses of demographic and clinical characteristics were performed by use of ACTs at baseline and follow up. The association between ACT use and clinical outcomes was assessed with the use of unadjusted and adjusted multinomial logistic regression models. Of the overall study population (n= 905), 59%used ACTs at baseline. A greater proportion of patients who used ACTs at baseline and follow up continuously had Pseudomonas aeruginosa (47%vs36%; P= .021) and experienced an exacerbation (81%vs59%; P< .0001) or hospitalization for pulmonary illness (32%vs22%; P= .001) in the prior two years, compared with those patients who did not use ACTs. Fifty-eight percent of patients who used ACTs at baseline did not use ACTs at 1-year follow up. There was no significant change in pulmonary function for those who used ACTs at follow up, compared with baseline. Patients who used ACTs at baseline and follow up had greater odds for experiencing exacerbations at follow up compared with those patients who did not use ACTs. In patients with bronchiectasis and a productive cough, ACTs are used more often if the patients have experienced a prior exacerbation, hospitalization for pulmonary illness, or had P aeruginosa. There is a significant reduction in the use of ACTs at 1-year follow up. The odds of the development of a bronchiectasis exacerbation are higher in those patients who use ACTs continuously, which suggests more frequent use in an ill bronchiectasis population.

Inpatient prophylaxis in cancer patients: where is the evidence?

Venous thromboembolism (VTE) is a leading cause of preventable in-hospital mortality. Cancer is associated with an increased risk of VTE which is further compounded by acute hospitalization for medical illness. The absolute incidence of VTE of hospitalized cancer patients ranges between 2% and 17% but the rates vary considerably depending on the type of study, method of VTE surveillance and whether pharmacologic thromboprophylaxis is administered. Complicating the interpretation of thromboprophylaxis trials is the paucity of reported data on the relative benefit of thromboprophylaxis relative to an increased risk of hemorrhage inherent to cancer patients. Efforts over the last decade have improved the rates of adherence to in-hospital pharmacologic thromboprophylaxis regimens. Whether these efforts also improve outcomes continues to be debated. In this review, the prevalence of VTE and hemorrhage in hospitalized cancer patients is presented in the context of pharmacologic thromboprophylaxis data along with a discussion of emerging approaches towards VTE risk-adapted prescription of antithrombotics during hospitalization.

Respiratory Syncytial Virus-Associated Hospitalizations Among Adults With Chronic Medical Conditions.

In contrast with respiratory disease caused by influenza, information on the risk of respiratory syncytial virus (RSV) disease among adults with chronic medical conditions (CMCs) is limited. We linked population-based surveillance of acute respiratory illness hospitalizations to national administrative data to estimate seasonal RSV hospitalization rates among adults aged 18-80 years with the following preexisting CMCs: chronic obstructive pulmonary disease (COPD), asthma, congestive heart failure (CHF), coronary artery disease (CAD), cerebrovascular accidents (CVA), diabetes mellitus (DM), and end-stage renal disease (ESRD). Age- and ethnicity-adjusted rates stratified by age group were estimated. Among 883 999 adult residents aged 18-80 years, 281 RSV-positive hospitalizations were detected during 2012-2015 winter seasons. Across all ages, RSV hospitalization rates were significantly higher among adults with COPD, asthma, CHF, and CAD compared with those without each corresponding condition. RSV hospitalization rates were significantly higher among adults with ESRD aged 50-64 years and adults with DM aged 18-49 years and 65-80 years compared with adults in each age group without these conditions. No increased risk was seen for adults with CVA. The CMC with the highest risk of RSV hospitalization was CHF (incidence rate ratio [IRR] range, 4.6-36.5 across age strata) and COPD (IRR range, 9.6-9.7). Among RSV-positive adults, CHF and COPD were independently associated with increased length of hospital stay. Adults with specific CMCs are at increased risk of RSV hospitalizations. Age affects this relationship for some CMCs. Such populations maybe relevant for future RSV prevention strategies.

An Outbreak Preparedness and Mitigation Approach in Home Health and Personal Home Care During the COVID-19 Pandemic.

The acute respiratory disease COVID-19, caused by the novel Coronavirus SARS-CoV-2, is a worldwide pandemic affecting millions of people. The methodology that organizations who provide home health and personal home care services are using to respond to this pandemic has not yet been characterized. In this report, we describe our approach to comprehensive outbreak suppression and report an initial case series of COVID-19 positive patients receiving home-based services. We implemented enhanced infection control procedures across our affiliates, and we communicated these protocols to our offices using multi-faceted methods. Using custom built software applications enabling us to track patient and employee cases and exposures, we leveraged current public health recommendations to identify cases and to suppress transmission. In the 100-day period between January 20, 2020 and April 30, 2020, our affiliates provided services to 67 COVID-19 positive patients (<0.3% of census). Twenty patients were referred to home health post hospitalization for COVID-19 related illness, whereas 47 were found to have COVID-19 while living in community settings. Of those who were found to have COVID-19 in the community, 17 (39%) required subsequent hospitalization. Hospitalized patients had an average age of 74.5 ± 18, and 53% were male. There were 13 deaths (76%) among those hospitalized from the community with COVID-19 related illness. A highly coordinated and frequently communicated approach to infection control, case identification and employee screening can be performed by home health and personal home care organizations. Studies that further assess risks and predictors of illness severity in home-based COVID-19 patients are needed.

The effect of patient-managed stress dosing on electrolytes and blood pressure in acute illness in children with adrenal insufficiency.

Adrenal crises (AC) are acute episodes of adrenal insufficiency (AI). Manifestations include hypotension and electrolyte disturbances. Glucocorticoid stress dosing (SD) can prevent AC progression, but its effect on physiological parameters has not been assessed in a 'real world setting'. To assess the effect of prior self-managed glucocorticoid dose escalation on physiological markers in children with congenital adrenal hyperplasia (CAH) presenting to hospital for an acute illness. An audit of records of all children with CAH presenting to paediatric referral hospital between 2000 and 2015. Potassium, sodium and glucose levels, and hypotension were compared between children who had and had not used SD. There were 321 attendances by patients with CAH and an acute illness during the study period. Any form of SD was used by 64.2% (n=206); intramuscular (IM) hydrocortisone was used by 22.1% (n=71) and oral only by 41.7% (n=134). Use of SD (oral and/or IM) was associated with a significantly lower mean potassium level (4.02±0.71 vs. 4.27±0.79mmol/l, P<.05). Linear regression analysis showed that age (beta: -0.04years (95% CI -0.06, -0.02)), diarrhoea (beta: -0.41 (95% CI -0.06, -0.02)) and any form of stress dosing (oral, IM or both) (beta: -0.29 (95% CI -0.55, -0.04)) were each independently and significantly associated with potassium levels. SD was not significantly associated with sodium or glucose concentrations or with estimates of hypotension. Patient-initiated SD resulted in a significant reduction in hyperkalaemia and lowered mean potassium levels in paediatric patients with CAH but did not alter significantly sodium and glucose concentrations or incidences of hypotension.

74Subclinical atrial fibrillation before and after acute medical illness or noncardiac surgery: insights from ASSERT

Abstract OnBehalf ASSERT Investigators Background Atrial fibrillation (AF) is frequently detected perioperatively or during acute medical illness. It is unclear if such AF is reversible and unlikely to recur, or is a manifestation of paroxysmal AF. Objective To compare the prevalence of pacemaker-detected, subclinical AF (atrial rate &amp;gt;190 bpm) before and after hospitalization for noncardiac surgery or medical illness in patients without a history of clinical AF. Methods ASSERT enrolled patients who were &amp;gt;65 years old and had hypertension but no known AF. Pacemakers and defibrillators recorded episodes of subclinical AF. We identified participants who were hospitalized for noncardiac surgery or medical illness, and created heart rhythm profiles, centred on the day of hospitalization. We compared the prevalence of subclinical AF before and after hospitalization. We blanked the 30 days before hospitalization, because of uncertainty in defining the precise onset of illness. Results Among 2580 patients, 436 had a documented surgical or medical hospitalization. In the 30 days following a first hospitalization, 43 patients (9.9%) had &amp;gt;1 episode of &amp;gt;6 minutes of subclinical AF; 20 (4.6%) had &amp;gt;6 hours and 13 (3%) had &amp;gt;24 hours. A higher proportion of patients had &amp;gt;1 episode of subclinical AF &amp;gt;6 minutes in the 30 days following a first surgical or medical hospitalization, as compared to the period between 30 and 60 days before hospitalization (9.9% versus 4.4%, P &amp;lt; 0.001). There was no significant difference when comparing 0-90 days after hospitalization to 30-120 days before (13.7% versus 10.6%, P = 0.1). Similar results were observed for the same comparisons with episodes &amp;gt;6 hours (4.6% versus 2.3%, P = 0.03 and 5.9% versus 5.6%, P = 0.8, respectively). The majority of patients with subclinical AF in the 30 days following hospitalization had at least one episode of subclinical AF of the same duration in the 6 months prior (50% for episodes &amp;gt;6 minutes; 69% for &amp;gt;6 hours and 60% for &amp;gt;24 hours). Those who did have subclinical AF in the 30 days following hospitalization were more likely to have had subclinical AF in the past 6 months than those who did not (OR 7.2 95%CI 3.2-15.8 for episodes &amp;gt;6 minutes; OR 32.6, 95%CI 10.3-103.4 for &amp;gt;6 hours and OR 36.3 95%CI 9.0-146.0 for &amp;gt;24 hours). Conclusions The prevalence of subclinical AF increased following hospitalization for noncardiac surgery or medical illness. However, most patients with subclinical AF following hospitalization had previously experienced similar episodes, particularly those with longer episodes of subclinical AF.

Respiratory Syncytial Virus Prophylaxis in Immunocompromised Children

Immunocompromised children are at increased risk for respiratory syncytial virus (RSV) infection with associated morbidity and mortality. Prophylaxis is usually provided to these children on a case-by-case basis. Immunocompromised children who received ≥1 injection of palivizumab were prospectively enrolled across 32 Canadian sites, between 2005 and 2017, during the RSV season. We assessed respiratory illness hospitalization (RIH) and RSV-related hospitalization (RSVH) hazard ratios (HRs) in immunocompromised children versus infants' prophylaxed for standard indications (SI: prematurity ≤35 weeks' gestation, bronchopulmonary dysplasia, and congenital heart disease) and complex medical disorders (CMD). Data were analyzed using t-tests, χ and Cox proportional hazards adjusted for confounders. A total of 25,003 infants were recruited; 214 immunocompromised, 4283 CMD, 20,506 SI. On average, children received 4.4 ± 1.3 injections. A total of 16,231 children were perfectly adherent (58.4% immunodeficiency, 68.9% CMD, 64.2% SI; P < 0.0005). A higher proportion of immunocompromised children were aboriginal and exposed to smoking compared with CMD and SI. Immunocompromised children also had a higher median; gestational and enrollment age and birth weight compared with CMD and SI. Immunodeficient children had a higher RIH risk compared with SI (HR = 2.4, 95% confidence interval, 1.3-4.7, P = 0.009) but were similar to CMD (HR = 1.7, 95% confidence interval, 0.9-3.4, P = 0.118). RSVH in prophylaxed, immunocompromised children was similar to CMD (HR < 0.005, P = 0.955) and SI (HR < 0.005, P = 0.953). Immunocompromised children who received palivizumab had an increased RIH hazard compared with the SI group. Similar RSVH hazard between the 3 groups suggests that immunocompromised children may benefit from palivizumab during the RSV season.

Are Play Items and Interaction Activities at Home Associated with Developmental Outcomes in Children with Moderate Acute Malnutrition?

Abstract Objectives To assess the association between play and interaction, and developmental outcomes in children with moderate acute malnutrition (MAM) in a prospective cohort of hospitalized children in Malawi and Uganda (http://www.chainnetwork.org). Methods Children (age 2– 23 months) requiring hospitalization for acute illness were enrolled from January 2017 till December 2018. Children meeting WHO criteria for MAM by mean upper arm circumference (MUAC) were included in this sub-analysis. Child development was assessed using the Malawi Developmental Assessment Tool at discharge and 180-day follow-up. The Family Care Indicator (FCI) evaluated the number of play items and interactions in the home. Developmental outcomes at discharge and follow-up were assessed using paired t-test. Linear regression analysis examined associations between FCI score and developmental outcomes at follow-up, with adjustment for sex, prematurity, height-for-age z-score and HIV status, parental education, household assets, and maternal mental health. Results 128 children with MAM (52.3% male, mean age 11.3 months (±4.5) were included (mean MUAC 120 mm ± 3.2). Children were excluded for: pre-existing neurodisability (n = 5), death during follow-up (n = 4), and loss to follow-up (n = 22). At discharge 24.4% of the children had delays in the gross motor domain, 18.7% in the fine motor domain, 4.1% in the language domain and 7.3% in the social domain. Over the 6-month study period, significant improvements (P &amp;lt; 0.001) in the mean difference of gross motor (1.3), fine motor (0.83) and social domain (0.59) Z-scores were observed. No significant change was identified in the language domain Z-score. Adjusted linear regression revealed that a one-point increase in the number of play items was associated with an increase in gross motor z-score of 0.16 (95% CI 0.01–0.32, P = 0.04) and a one point increase in interaction activities was associated with an increase in language z-score of 0.27 (95% CI 0.03–0.51, P = 0.03) at follow-up. Conclusions Children with MAM admitted for an acute illness showed significant improvements in developmental outcomes at 180-day follow-up. The role of play and interaction activities at home should be further investigated for their potential to promote developmental outcomes in children with MAM.

Recommendations for older adults\u2019 physical activity and sedentary behaviour during hospitalisation for an acute medical illness: an international Delphi study

BackgroundImmobility is major contributor to poor outcomes for older people during hospitalisation with an acute medical illness. Yet currently there is no specific mobility guidance for this population, to facilitate sustainable changes in practice. This study aimed to generate draft physical activity (PA) and sedentary behaviour (SB) recommendations for older adults’ during hospitalisation for an acute medical illness.MethodsA 4-Round online Delphi consensus survey was conducted. International researchers, medical/nursing/physiotherapy clinicians, academics from national PA/SB guideline development teams, and patients were invited to participate. Round 1 sought responses to open-ended questions. In Rounds 2–3, participants rated the importance of items using a Likert scale (1–9); consensus was defined a priori as: ≥70% of respondents rating an item as “critical” (score ≥ 7) and ≤ 15% of respondents rating an item as “not important” (score ≤ 3). Round 4 invited participants to comment on draft statements derived from responses to Rounds 1–3; Round 4 responses subsequently informed final drafting of recommendations.ResultsForty-nine people from nine countries were invited to each Round; response rates were 94, 90, 85 and 81% from Rounds 1–4 respectively. 43 concepts (items) from Rounds 2 and 3 were incorporated into 29 statements under themes of PA, SB, people and organisational factors in Round 4. Examples of the final draft recommendations (being the revised version of statements with highest participant endorsement under each theme) were: “some PA is better than none”, “older adults should aim to minimise long periods of uninterrupted SB during waking hours while hospitalised”, “when encouraging PA and minimising SB, people should be culturally responsive and mindful of older adults’ physical and mental capabilities” and “opportunities for PA and minimising SB should be incorporated into the daily care of older adults with a focus on function, independence and activities of daily living”.ConclusionsThese world-first consensus-based statements from expert and stakeholder consultation provide the starting point for recommendations to address PA and SB for older adults hospitalised with an acute medical illness. Further consultation and evidence review will enable validation of these draft recommendations with examples to improve their specificity and translation to clinical practice.

Melatonin Use in Hospitalized Children for Non-Anesthetic Indications: A Systematic Review.

Melatonin, a potent free radical scavenger, plays an important role in homeostasis of cell and organ physiology. The increased demand and synthesis from the pineal gland during times of oxidative stress suggests a potential benefit of melatonin supplementation during hospitalization for acute illness. Yet, the paucity of clinical studies for non-anesthetic-associated indications in pediatric populations hampers the safe, effective, and consistent use of melatonin. The objective of this study was to systematically review published studies of melatonin use for non-sedative and non-analgesic indications in hospitalized pediatric patients. We conducted a search of PubMed, EMBASE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Web of Science, and Scopus databases for articles on the use of melatonin for pediatric patients in a hospital setting. Thirteen eligible studies, all in neonates, were identified. Data elements extracted included study design, number of study subjects, indication for melatonin therapy, and melatonin regimen (formulation, dosage, and duration). Because study methodologies were very heterogeneous, a quantitative synthesis of the published findings was not possible. The identified studies were therefore categorized by the indication of melatonin (adjuvant-antioxidant or anti-inflammatory therapy) in the following specific disease states: (i) acute infections, (ii) respiratory distress syndrome, (iii) neurologic injury, and (iv) jaundice. The current data suggest that melatonin is safe for use in hospitalized neonates. Melatonin may be beneficial for reducing inflammatory markers in neonatal patients with disease states and clinical sequelae that are associated with increased inflammation and oxidative stress. Melatonin, in conjunction with phototherapy, is not superior to use of vitamin D with phototherapy for treatment of neonatal jaundice. However, studies in other pediatric populations are needed given widespread use across clinical inpatient settings.

AYUSH 64, a polyherbal Ayurvedic formulation in Influenza-like illness - Results of a pilot study

BackgroundInfluenza-like Illness (ILI) refers to a wide range of viral infections with an important cause of morbidity and mortality worldwide. The global incidence of ILI is estimated at 5–10% in adults and 20–30% in children. In India influenza accounts for 20–42% of monthly acute medical illness hospitalizations during the peak rainy season. AYUSH-64, a poly-herbal drug, is in practice for 40 years for various clinical conditions like fevers, microfilaremia, and inflammatory conditions. ObjectiveA pilot study was conducted to evaluate the safety and efficacy of Ayurvedic formulation, AYUSH-64 in clinically diagnosed ILI for accelerating the recovery. Material and MethodsA prospective, open-label, nonrandomized, single group, single-center pilot clinical study with pre-test and post-test design was conducted at Raja Ramdeo Anandilal Podar Central Ayurveda Research Institute for Cancer, Mumbai, an institute of Central Council for Research in Ayurvedic Sciences (CCRAS) between June 2018 and July 2019. A total of 38 participants of clinically diagnosed ILI (18–65 years) were studied with an one-week intervention of ‘AYUSH 64’ in a dose of 3 gm/day and three weeks post-treatment observation period. Assessment of parameters viz. improvement in the symptoms of ILI, frequency of usage of acetaminophen, antihistaminic and cough syrup, hematology, liver function and kidney function tests along with incidence of secondary complications, and time to return to a normal routine was done. ResultsOne-week intervention of AYUSH 64 helped to recover from ILI symptoms with reduced frequency of usage of acetaminophen and antihistaminic. The intervention was safe on hematology and biochemical parameters. No serious adverse effects were observed during the study. ConclusionAYUSH 64 along-with standard care in ILI is safe and efficacious and this may be used in other viral infections with pyrexia as add-on to standard care for early recovery and better outcome.

Analysis of MarketScan Data for Immunosuppressive Conditions and Hospitalizations for Acute Respiratory Illness, United States.

Increasing use of immunosuppressive biologic therapies poses a challenge for infectious diseases. Immunosuppressed patients have a high risk for influenza complications and an impaired immune response to vaccines. The total burden of immunosuppressive conditions in the United States, including those receiving emerging biologic therapies, remains unknown. We used the national claims database MarketScan to estimate the prevalence of immunosuppressive conditions and risk for acute respiratory illnesses (ARIs). We studied 47.2 million unique enrollees, representing 115 million person-years of observation during 2012–2017, and identified immunosuppressive conditions in 6.2% adults 18–64 years of age and 2.6% of children <18 years of age. Among 542,105 ARI hospitalizations, 32% of patients had immunosuppressive conditions. The risk for ARI hospitalizations was higher among enrollees with immunosuppression than among nonimmunosuppressed enrollees. Future efforts should focus on developing improved strategies, including vaccines, for preventing influenza in immunosuppressed patients, who are an increasing population in the United States.

RSV and non-RSV illness hospitalization in RSV immunoprophylaxis recipients: A systematic literature review.

Respiratory syncytial virus (RSV) immunoprophylaxis (IP) has been shown to reduce RSV hospitalization rates in high-risk infants; however, it is unclear whether RSV IP is associated with increased risk of non-RSV disease, particularly non-RSV hospitalizations. We conducted a systematic literature review to understand the occurrences of non-RSV disease and/or non-RSV hospitalizations in published studies of RSV IP. Cochrane, Embase, and PubMed databases were searched and reviewed to summarize data regarding the incidence of RSV and non-RSV respiratory disease among RSV IP recipients and controls in randomized and non-randomized studies. Independent investigators screened and selected studies for inclusion. Risk-of-bias assessment was conducted to assess strength/validity of the data using the Jadad scoring system and Downs and Black quality assessment tool, where appropriate. Twenty studies were included for review (5 randomized controlled trials [RCTs]; 15 non-randomized studies). RCTs of RSV IP demonstrated reductions in RSV hospitalizations and all-cause hospitalizations, with no increase in hospitalizations for non-RSV disease. Non-randomized studies also demonstrated reduced RSV hospitalizations in RSV IP recipients but had mixed results in assessments of hospitalizations for non-RSV disease. When RSV IP recipients and controls were more similar in disease severity risk, results of non-randomized studies aligned more closely with RCTs. Observations of increased non-RSV hospitalization rates among RSV IP recipients in some non-randomized studies could be primarily explained by differences in the clinical characteristics between RSV IP recipients and controls.

An international cohort study of birth outcomes associated with hospitalized acute respiratory infection during pregnancy

ObjectivesFindings during the 2009 pandemic suggest severe maternal infection with pandemic influenza had adverse perinatal health consequences. Limited data exist evaluating the perinatal health effects of severe seasonal influenza and non-influenza infections during pregnancy. MethodsA retrospective cohort of pregnant women from Australia, Canada, Israel, and the United States was established using birth records to identify pregnancies and birth outcomes and hospital and laboratory testing records to identify influenza and non-influenza associated acute respiratory or febrile illness (ARFI) hospitalizations. ARFI hospitalized women were matched to non-hospitalized women (1:4) by country and season of conception. Log-binomial regression was used to estimate the relative risk (aRR) of preterm birth (PTB), small-for-gestational-age (SGA), and low birthweight (LBW) birth, adjusting for pre-existing medical conditions, maternal age, and parity. Results950 pregnant women hospitalized with an ARFI were matched with 3,800 non-hospitalized pregnant women. Compared to non-hospitalized women, risk of PTB was greater among women hospitalized with influenza-associated ARFI (aRR: 1.57; 95% CI: 1.15–2.15) and non-influenza ARFI (aRR: 2.78; 95% CI: 2.12–3.65). Similar results were observed for LBW; there were no associations with SGA birth. ConclusionsARFI hospitalization during pregnancy was associated with increased risk of PTB and LBW.

Defining heat waves and extreme heat events using sub-regional meteorological data to maximize benefits of early warning systems to population health

BackgroundExtreme heat events have been consistently associated with an increased risk of hospitalization for various hospital diagnoses. Classifying heat events is particularly relevant for identifying the criteria to activate early warning systems. Heat event classifications may also differ due to heterogeneity in climates among different geographic regions, which may occur at a small scale. Using local meteorological data, we identified heat waves and extreme heat events that were associated with the highest burden of excess hospitalizations within the County of San Diego and quantified discrepancies using county-level meteorological criteria. MethodsEighteen event classifications were created using various combinations of temperature metric, percentile, and duration for both county-level and climate zone level meteorological data within San Diego County. Propensity score matching and Poisson regressions were utilized to ascertain the association between heat wave exposure and risk of hospitalization for heat-related illness and dehydration for the 1999–2013 period. We estimated both relative and absolute risks for each heat event classification in order to identify optimal definitions of heat waves and extreme heat events for the whole city and in each climate zone to target health impacts. ResultsHeat-related illness differs vastly by level (county or zone-specific), definition, and risk measure. We found the county-level definitions to be systematically biased when compared to climate zone definitions with the largest discrepancy of 56 attributable hospitalizations. The relative and attributable risks were often minimally correlated, which exemplified that relative risks alone are not adequate to optimize heat waves definitions. ConclusionsDefinitions based on county-level defined thresholds do not provide an accurate picture of the observed health effects and will fail to maximize the potential effectiveness of heat warning systems. Absolute rather than relative risks are a more appropriate measure to define the set of criteria to activate early warnings systems and thus maximize public health benefits.
