Risk Factors for SARS-CoV-2 Infection Among US Healthcare Personnel, May-December 2020.

To determine risk factors for coronavirus disease (COVID-19) among US healthcare personnel (HCP), we conducted a case-control analysis. We collected data about activities outside the workplace and COVID-19 patient care activities from HCP with positive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) test results (cases) and from HCP with negative test results (controls) in healthcare facilities in 5 US states. We used conditional logistic regression to calculate adjusted matched odds ratios and 95% CIs for exposures. Among 345 cases and 622 controls, factors associated with risk were having close contact with persons with COVID-19 outside the workplace, having close contact with COVID-19 patients in the workplace, and assisting COVID-19 patients with activities of daily living. Protecting HCP from COVID-19 may require interventions that reduce their exposures outside the workplace and improve their ability to more safely assist COVID-19 patients with activities of daily living.

Flavored alcoholic beverage use, risky drinking behaviors, and adverse outcomes among underage drinkers: results from the ABRAND Study.

OBJECTIVES: We examined associations between consumption of different types of flavored alcoholic beverages (FABs) and risky drinking and drinking-related harms among underage drinkers. METHODS: For the Alcohol Brand Research among Underage Youth study, we applied multivariable logistic regression analyses to data from underage drinkers (n = 1031, aged 13-20 years), recruited from a national Internet panel in 2011 to 2012, to estimate associations between consumption of malt-based drinks; spirits-based, premixed- or ready-to-drink cocktails; and supersized alcopops, alone or in combination, and alcohol-related outcomes. RESULTS: After adjustment for confounding variables, the exclusive consumption of alcopops was associated with episodic heavy drinking (odds ratio [OR] = 4.35; 95% confidence interval [CI] = 1.24, 15.31; P < .05) and alcohol-related injuries (OR = 6.25; 95% CI = 1.34, 29.10; P < .05). Exclusive consumption of cocktails was associated with episodic heavy drinking (odds ratio [OR] = 2.61; 95% CI = 1.26, 5.41; P < .05) and injuries requiring medical attention (OR = 6.50; 95% CI = 2.09, 20.17; P < .001. Exclusive consumption of 2 or more FABs was associated with episodic heavy drinking (OR = 2.78; 95% CI = 1.25, 6.16; P < .05), fighting (OR = 3.30; 95% CI = 1.46, 7.47; P < .001), and alcohol-related injuries (OR = 2.83; 95% CI = 1.43, 5.58; P < .001). CONCLUSIONS: FABs present an emerging public health problem among youths.

Effects of crushed ice and wetted ice on hamstring flexibility.

Flexibility, which is the ability to move freely through a full range of motion (ROM), is desired to enhance the performance and decrease the likelihood of muscle injury. There are different techniques used to increase ROM and cryotherapy techniques to facilitation flexibility gains. However, the combination of stretching and type of cryotherapy agents are still confounding. The purpose was to determine which type of cryotherapy, crushed or wetted ice, would produce the greatest gains in hamstring ROM when followed by proprioceptive neuromuscular facilitation (PNF) stretching. Fifteen healthy subjects underwent 3 treatment conditions: crushed ice bag (crushed ice), wetted ice bag (wetted ice), and no ice bag (no ice). Subject's hamstring ROM was measured at baseline, then again after a 20-minute cryotherapy treatment session. Subjects were then stretched using a slow-reversal-hold-relax PNF technique followed by a final ROM measurement. A repeated measures analysis of variance showed significant differences between cryotherapy and measurement conditions. Post hoc testing indicated that no ice (75.49 ± 12.19° C) was significantly different from wetted ice (81.73 ± 10.34° C) and crushed ice (81.62 ± 13.19° C) at the end of the treatment session, and that no ice (85.27 ± 13.83° C) was significantly different than wetted ice (89.44 ± 11.31° C) and crushed ice (89.16 ± 13.78° C) after the stretching session. However, there were no differences between wetted ice and crushed ice. Results indicate that strength and conditioning specialists can increase ROM with both forms of ice in combination with PNF stretching more so than when using no ice at all.

Brand-specific consumption of flavored alcoholic beverages among underage youth in the United States.

BACKGROUND: Although several studies have identified flavored alcoholic beverages (FABs) as being popular among underage drinkers, no previous study has ascertained the prevalence of brand-specific FAB consumption among a national sample of underage youth. OBJECTIVES: To ascertain the brand-specific consumption prevalence and consumption share of FABs among a national sample of underage drinkers in the United States. METHODS: In 2012, we conducted an online, self-administered survey of a national sample of 1031 underage drinkers, ages 13-20 years, to determine the prevalence of past 30-day consumption for each of 898 alcoholic beverage brands, including 62 FABs, and each brand's youth consumption share, based on the estimated total number of standard drinks consumed. There were three brand-specific outcome measures: prevalence of consumption, prevalence of consumption during heavy episodic drinking, and consumption share, defined as the percentage of the total drinks consumed by all respondents combined that was attributable to a particular brand. RESULTS: The FAB brands with the highest prevalence of past 30-day consumption were Smirnoff malt beverages, 17.7%; Mike's, 10.8%; Bacardi malt beverages, 8.0%; and Four Loko/Four MaXed, 6.1%. Just five brands accounted for almost half (49.1%) of the total consumption share by volume within the FAB category. CONCLUSION: Flavored alcoholic beverages are highly popular among underage drinkers, and the FAB brand preferences of this group are highly concentrated among a small number of brands. To decrease the consumption of FABs by underage youth, all states should reclassify these beverages as distilled spirits rather than beer.

Residential social vulnerability among healthcare personnel with and without severe acute respiratory coronavirus virus 2 (SARS-CoV-2) infection in Five US states, May-December 2020.

OBJECTIVE: To characterize residential social vulnerability among healthcare personnel (HCP) and evaluate its association with severe acute respiratory coronavirus virus 2 (SARS-CoV-2) infection. DESIGN: Case-control study. SETTING: This study analyzed data collected in May-December 2020 through sentinel and population-based surveillance in healthcare facilities in Colorado, Minnesota, New Mexico, New York, and Oregon. PARTICIPANTS: Data from 2,168 HCP (1,571 cases and 597 controls from the same facilities) were analyzed. METHODS: HCP residential addresses were linked to the social vulnerability index (SVI) at the census tract level, which represents a ranking of community vulnerability to emergencies based on 15 US Census variables. The primary outcome was SARS-CoV-2 infection, confirmed by positive antigen or real-time reverse-transcriptase- polymerase chain reaction (RT-PCR) test on nasopharyngeal swab. Significant differences by SVI in participant characteristics were assessed using the Fisher exact test. Adjusted odds ratios (aOR) with 95% confidence intervals (CIs) for associations between case status and SVI, controlling for HCP role and patient care activities, were estimated using logistic regression. RESULTS: Significantly higher proportions of certified nursing assistants (48.0%) and medical assistants (44.1%) resided in high SVI census tracts, compared to registered nurses (15.9%) and physicians (11.6%). HCP cases were more likely than controls to live in high SVI census tracts (aOR, 1.76; 95% CI, 1.37-2.26). CONCLUSIONS: These findings suggest that residing in more socially vulnerable census tracts may be associated with SARS-CoV-2 infection risk among HCP and that residential vulnerability differs by HCP role. Efforts to safeguard the US healthcare workforce and advance health equity should address the social determinants that drive racial, ethnic, and socioeconomic health disparities.

Characteristics of healthcare personnel with SARS-CoV-2 infection: 10 emerging infections program sites in the United States, April 2020-December 2021.

BACKGROUND: Understanding characteristics of healthcare personnel (HCP) with SARS-CoV-2 infection supports the development and prioritization of interventions to protect this important workforce. We report detailed characteristics of HCP who tested positive for SARS-CoV-2 from April 20, 2020 through December 31, 2021. METHODS: CDC collaborated with Emerging Infections Program sites in 10 states to interview HCP with SARS-CoV-2 infection (case-HCP) about their demographics, underlying medical conditions, healthcare roles, exposures, personal protective equipment (PPE) use, and COVID-19 vaccination status. We grouped case-HCP by healthcare role. To describe residential social vulnerability, we merged geocoded HCP residential addresses with CDC/ATSDR Social Vulnerability Index (SVI) values at the census tract level. We defined highest and lowest SVI quartiles as high and low social vulnerability, respectively. RESULTS: Our analysis included 7,531 case-HCP. Most case-HCP with roles as certified nursing assistant (CNA) (444, 61.3%), medical assistant (252, 65.3%), or home healthcare worker (HHW) (225, 59.5%) reported their race and ethnicity as either non-Hispanic Black or Hispanic. More than one third of HHWs (166, 45.2%), CNAs (283, 41.7%), and medical assistants (138, 37.9%) reported a residential address in the high social vulnerability category. The proportion of case-HCP who reported using recommended PPE at all times when caring for patients with COVID-19 was lowest among HHWs compared with other roles. CONCLUSIONS: To mitigate SARS-CoV-2 infection risk in healthcare settings, infection prevention, and control interventions should be specific to HCP roles and educational backgrounds. Additional interventions are needed to address high social vulnerability among HHWs, CNAs, and medical assistants.

Communicating With Unconscious Patients: An Overview.

BACKGROUND: Nurses are told to speak to their unconscious patients because hearing is said to be the last sense to depart. There was little reliable evidence before the 1990s that patients in an unconscious state could hear and understand what was being said. That led to reluctance on the part of health professionals to communicate with these unresponsive patients. OBJECTIVE: This historical overview aims to present researched evidence from the 1990s to the present detailing awareness that occurs in unconscious patients, when that awareness increases, and how to detect that awareness. It also includes research about the benefits of communicating with unconscious patients and descriptions of how registered nurses and other health care professionals, from a postsurvey after a continuing education course on experiences of unconscious patients, plan to communicate with unconscious patients. METHODS: A literature search was conducted, which included more than 150 articles and books about experiences of unconscious patients in several electronic databases, including PubMed, CINAHL, and the British Nursing Index. In addition, an analysis of 105 postcourse responses by registered nurses (89%) and other health professionals (11%), licensed practical nurses, emergency medical technicians, and cardiac technicians after taking a continuing education course on experiences of previously unconscious patients were analyzed. RESULTS: The Glasgow Coma Scale and the Full Outline of Unresponsiveness scale are helpful behavioral tools to identify levels of coma but miss detecting awareness in patients who can hear and understand but cannot move. The estimates are that 25% to 40% (J Trauma. 1975;15:94-98; J Neurosci Nurs. 1988;20:223-228; J Neurosci Nurs. 1990;22(1):52-53; Am J Crit Care. 1995;3:227-232) of patients diagnosed with a disorder of consciousness can hear and understand what is being said in their environment. Substantial evidence supports that isolation and loneliness, such as experienced by some patients perceived to be unaware, can be physically and psychologically harmful. CONCLUSIONS: Strong evidence shows that some patients diagnosed as being in a vegetative state can hear and understand what is being said in their environment. Interviews with previously unconscious patients and electrophysiological methods show that awareness can be detected in patients perceived to be unconscious. There is documented evidence that patients experience awareness when going into unconsciousness, even when they appear unaware and when moved. To our knowledge, these times have not been researched using electrophysiological devices but established from interviews.

Auditory comprehension outcomes in children who receive a cochlear implant before 12 months of age.

OBJECTIVE: The U.S. Food and Drug Administration guidelines for cochlear implantation (CI) include age greater than 12 months. Studies have suggested that implantation in children younger than 12 months with congenital deafness may be associated with better spoken language outcomes. Compare auditory comprehension (AC) outcomes for children with congenital deafness who received CI less than 12 months of age to those implanted at 12 to 24 months of age. METHODS: Retrospective review of prospectively collected data in consecutively implanted patients under 2 years of age who received CI and had post-CI Preschool Language Scale (PLS)-AC scores. Receptive language was assessed with the AC subtest of the PLS. Patients without pre-CI PLS-AC scores were excluded. The association between age at implantation and post-CI PLS-AC scores up to 2 years after CI surgery was modeled using a linear mixed-effects model. Time from CI surgery, number of implants, risk factors for language delay, pre-CI PLS-AC score, and sex were included in the model. Patients implanted less than 12 months of age were compared to those implanted between 12 and 24 months. RESULTS: Twenty-nine patients who had CI surgery by 12 months and 82 who had CI surgery between 12 and 24 months were included in the analysis. Younger age at implantation and better pre-CI PLS-AC scores were significantly associated with better post-CI PLS-AC scores. CONCLUSION: Cochlear implantation in children with congenital deafness less than 12 months of age was associated with better PLS-AC than in children implanted over 12 months of age up to 2 years after implantation. LEVEL OF EVIDENCE: 4 Laryngoscope, 130:776-781, 2020.

Increasing Alcohol Taxes: Analysis of Case Studies From Illinois, Maryland, and Massachusetts.

OBJECTIVE: The effectiveness of alcohol taxes in reducing excessive alcohol consumption and related problems is well established in research, yet increases in U.S. state alcohol taxes are uncommon. This study examined how alcohol tax increases occurred recently in three U.S. states, what public health's role was, and what can be learned from those experiences. METHOD: Review of available documentation and news media content analysis provided context and, along with snowball sampling, helped identify proponents, opponents, and neutral parties in each state. Thirty-five semi-structured key informant interviews (lasting approximately 1 hour) were conducted, transcribed, and analyzed for common themes. RESULTS: State routes to alcohol tax increases varied, as did the role of public health research. Use of polling data, leveraging existing political champions, coalition building, drawing on past experience with legislative initiatives, deciding revenue allocation strategically, and generating media coverage were universal elements of these initiatives. Tax changes occurred when key policy makers sought new revenue sources or when proponents were able to build coalitions broader than the substance abuse field. CONCLUSIONS: Translation of scientific evidence on the effectiveness of increasing alcohol taxes into public health interventions may occur if legislative leaders seek new revenue sources or if broad-based coalitions can generate support and sustained media coverage. Policy makers are generally unaware of the health impact of alcohol taxes, although public health research may play a valuable role in framing and informing discussions of state alcohol tax increases as a strategy for reducing excessive alcohol use and alcohol-related harms.

The gastroprotective effect of tannins extracted from duhat (Syzygium cumini Skeels) bark on HCl/ethanol induced gastric mucosal injury in Sprague-Dawley rats.

The gastroprotective effect of quantified tannins (13.4%) from Syzygium cumini was determined. Gastric mucosal damage was induced in sixty eight rats by oral gavage administration of HCl/ethanol solution. For macroscopic and microscopic studies, 30 rats were divided into three groups consisting of a negative control, an Omeprazole group and a Tannins group. There was no significant difference in the number, size and surface area of macroscopic lesions between the three groups. Microscopic examination using Best's Ulcer Staging Index showed that Tannins had a very significant decrease in gastric mucosal damage with p<0.01. Average lymphocyte populations in the three groups showed no significant difference, although both the Tannins and Omeprazole group had fewer lymphocytes. Thirty-eight rats were studied for the amount of free radicals present after induction of gastric damage. A dose which consisted of 20.0 g tannins/kg rat weight showed significantly lower stomach free radical concentrations. These findings suggest that tannins extracted from S. cumini have gastroprotective and anti-ulcerogenic effects.

Efficacy and the strength of evidence of U.S. alcohol control policies.

BACKGROUND: Public policy can limit alcohol consumption and its associated harm, but no direct comparison of the relative efficacy of alcohol control policies exists for the U.S. PURPOSE: To identify alcohol control policies and develop quantitative ratings of their efficacy and strength of evidence. METHODS: In 2010, a Delphi panel of ten U.S. alcohol policy experts identified and rated the efficacy of alcohol control policies for reducing binge drinking and alcohol-impaired driving among both the general population and youth, and the strength of evidence informing the efficacy of each policy. The policies were nominated on the basis of scientific evidence and potential for public health impact. Analysis was conducted in 2010-2012. RESULTS: Panelists identified and rated 47 policies. Policies limiting price received the highest ratings, with alcohol taxes receiving the highest ratings for all four outcomes. Highly rated policies for reducing binge drinking and alcohol-impaired driving in the general population also were rated highly among youth, although several policies were rated more highly for youth compared with the general population. Policy efficacy ratings for the general population and youth were positively correlated for reducing both binge drinking (r=0.50) and alcohol-impaired driving (r=0.45). The correlation between efficacy ratings for reducing binge drinking and alcohol-impaired driving was strong for the general population (r=0.88) and for youth (r=0.85). Efficacy ratings were positively correlated with strength-of-evidence ratings. CONCLUSIONS: Comparative policy ratings can help characterize the alcohol policy environment, inform policy discussions, and identify future research needs.

Comparison of indices of vitamin A status in children with chronic liver disease.

Malabsorption of fat-soluble vitamins is a major complication of chronic cholestatic liver disease. The most accurate way to assess vitamin A status in children who have cholestasis is unknown. The goal of this study was to assess the accuracy of noninvasive tests to detect vitamin A deficiency. Children with chronic cholestatic liver disease (n = 23) and noncholestatic liver disease (n = 10) were studied. Ten cholestatic patients were identified as vitamin A-deficient based on the relative dose response (RDR). Compared with the RDR, the sensitivity and specificity to detect vitamin A deficiency for each test was, respectively: serum retinol, 90% and 78%; retinol-binding protein (RBP), 40% and 91%; retinol/RBP molar ratio, 60% and 74%; conjunctival impression cytology, 44% and 48%; slit-lamp examination, 20% and 66%; tear film break-up time, 40% and 69%; and Schirmer's test, 20% and 78%. We developed a modified oral RDR via oral coadministration of d-alpha tocopheryl polyethylene glycol-1000 succinate and retinyl palmitate. This test had a sensitivity of 80% and a specificity of 100% to detect vitamin A deficiency. In conclusion, vitamin A deficiency is relatively common in children who have chronic cholestatic liver disease. Our data suggest that serum retinol level as an initial screen followed by confirmation with a modified oral RDR test is the most effective means of identifying vitamin A deficiency in these subjects.
