Polycystic ovary syndrome (PCOS) is a common endocrine condition(1) associated with an increased risk of developing type 2 diabetes (T2D) and cardiovascular disease. Healthy lifestyle habits are critical in the management of PCOS(1), however, the public health system provides limited support for the lifestyle management of PCOS. Diabetes Victoria delivers a free program, ‘Life!’, to Victorian Residents at high risk of developing T2D, including those with PCOS. Life! is currently designed to meet general high-risk population needs, not specifically designed with PCOS in mind. This study aimed to evaluate the current Life! Program’s design, content and delivery against the needs of those with PCOS through co-design workshops with previous Life! participants who have PCOS (n = 14) and program facilitators (n = 5). A series of mixed-methods workshops were used to assess the current program, design an ideal program and prioritise unmet needs. Co-design was informed by the Linking and Amplifying User-Cantered Networks through Connected Health (LAUNCH) Roadmap(2) and the TiDiER checklist(3). Online worksheets, polls, open-ended questions and annotation of current material were used to aid participation and input. Four workshops (WS) were conducted online: two 3-hr (WS 1) and two 2-hr (WS 2). All were audio recorded and transcribed. Data was thematically synthesised using template analysis and findings from WS 1 were used to inform WS 2. Those with PCOS participated in the Life! program between 2018 and 2023, were aged between 24 and 52 years and the majority (93%) had a BMI greater than 25kg/m2. Program facilitators included dietitians, diabetes educators and a physiotherapist with 80% having more than 10 years’ experience. Overall participants wanted less generic and more PCOS-centric topics, less of an emphasis placed on weight loss with an equal focus on a range of health outcomes. Recommended topics included PCOS-centric lifestyle advice across diet, physical activity, sleep and mental health with an emphasis on how (practical strategies) and why (mechanistic understanding) healthy lifestyle behaviours should be applied. Participants desired the tone and sentiment used in the program’s language and imagery to be inclusive, gentle, non-stigmatising and positive. Participants desired a flexible approach to program delivery (a mix of in-person, online, one-on-one and group). One-on-one sessions were desired when receiving individualised advice and discussing sensitive topics, while group sessions were preferred for peer support, learning activities and reflections. People with PCOS desire a PCOS-centric lifestyle program with a focus on meaningful health outcomes, reducing the focus on weight loss, blended delivery, tailored and practical strategies with long-term support. Results will inform the development of a tailored lifestyle program that aims to better engage those with PCOS. Future community-based PCOS programs and clinicians are strongly recommended to incorporate these findings to improve engagement and consumer satisfaction.
Psychological and existential distress is prevalent among patients with life-threatening cancer, significantly impacting their quality of life. Psilocybin-assisted therapy has shown promise in alleviating these symptoms. This systematic review aims to synthesize the evidence on the efficacy and safety of psilocybin in reducing cancer-related distress.
Methods
We searched MEDLINE, APA PsycINFO, Cochrane database, Embase, and Scopus from inception to February 8, 2024, for randomized controlled trials (RCTs), open-label trials, qualitative studies, and single case reports that evaluated psilocybin for cancer-related distress. Data were extracted on study characteristics, participant demographics, psilocybin and psychotherapy intervention, outcome measures, and results. Two authors independently screened, selected, and extracted data from the studies. Cochrane Risk of Bias for RCTs and Methodological Index for Non-Randomized Studies criteria were used to evaluate study quality. This study was registered with PROSPERO (CRD42024511692).
Results
Fourteen studies met the inclusion criteria, comprising three RCTs, five open-label trials, five qualitative studies, and one single case report. Psilocybin therapy consistently showed significant reductions in depression, anxiety, and existential distress, with improvements sustained over several months. Adverse effects were generally mild and transient.
Significance of results
This systematic review highlights the potential of psilocybin-assisted therapy as an effective treatment for reducing psychological and existential distress in cancer patients. Despite promising findings, further large-scale, well-designed RCTs are needed to confirm these results and address existing research gaps.
Turbulent mixing in a supercritical CO$_2$ shear layer is examined using both experimental and numerical methods. Boundary conditions are selected to focus on the rarely studied near-critical regime, where thermophysical properties vary nonlinearly with respect to temperature and pressure. Experimental results are obtained via Raman spectroscopy and shadowgraphy, while numerical results are obtained via direct numerical simulation. The shear layer growth rate is found to be 0.2. Additionally, density profiles indicate a relaxation of density gradients between the mixed fluid and heavy fluid as the flow evolves downstream, which runs counter to existing supercritical shear layer data in the literature. The computational results identify significant anisotropy in the turbulence in the shear layer, which is discussed in terms of the development of regions of high density gradient magnitude. The Reynolds-averaged enstrophy budget at various streamwise locations indicates no significant dilatational or baroclinic contribution within the shear layer.
Harmful alcohol consumption has significant cost on health and is associated with lower quality of life (e.g., Lu et al. BMC Public Health 2022; 22:789). In Singapore, a significant proportion of the adult population exhibit alcohol misuse behaviours (e.g., Lim et al. BMC Public Health 2013; 13:992). Many patients admitted into general hospitals have excessive alcohol consumption and related problems. These admissions can be an opportunity for intervention due to accessibility to the individuals and their time (Saitz et al. Ann Intern Med 2007; 146 167-176). Some studies have suggested that brief alcohol interventions (BAI) delivered in general hospitals can be effective in reducing alcohol use. However, there has been less support for the benefits of BAI on wellbeing.
Objectives
This study investigated the effectiveness of BAI in improving perceived sense of wellbeing among male alcohol users admitted to a general hospital in Singapore.
Methods
108 male inpatients in various medical wards received BAI by the hospital’s addiction counsellors and completed the Personal Wellbeing Index (PWI) questionnaire. At a one-year follow-up via telephone, the PWI was again administered.
Results
Average PWI scores were higher at follow-up (M = 7.83, SD = 1.16) than during baseline admission (M = 7.60, SD = 1.12), p < 0.01. Further analyses found that scores improved significantly on PWI items related to standard of living (M = 7.36, SD = 1.41 vs M = 7.09, SD = 1.65; p < 0.05), health (M = 7.42, SD = 1.74 vs M = 6.62, SD = 1.87; p < 0.01) and achievement (M = 7.43, SD = 1.44 vs M = 6.98, SD = 1.64; p < 0.01). There were no significant differences in scores on the other PWI items between baseline and follow-up.
Conclusions
Conclusions: The results suggest that BAI can be beneficial in improving patients’ sense of wellbeing.
We aimed to study predictive factors for burnout (BO) among healthcare workers in a tertiary hospital in Singapore.
Objectives
We hypothesized that burnout would be assoiciated with singles, females, and foreign born staff recently moved into this country, unaccompanied by family members.
We further hypothesised that BO would be associated with those scoring less on resilience. Recognising that social support mitigated against stress and burnout, we hypothesized that those who perceived less support would be more prone to BO.
Methods
The study questionnaire was sent via corporate email to all staff with email access. We stressed that data would be fully anonymised. No financial rewards were given for participation which was carried out on a voluntary basis.
The following instruments were used, viz. F-SozU K-6, a brief form of the perceived social support questionnaire; Connor Davidson Resilience Scale; Oldenburg Burnout Inventory; Patient Health Questionnaire-4 item; Demand Control Support Questionnaire and Leisure Time Satisfaction Scale. Ethics approval for the study was sought from the SingHealth Centralised Institutional Review Board, which granted exemption of participant consent.
Analyses were performed using Stata version 17.0 (StataCorp. 2021), with statistical significance set as 2-sided 5% (p<0.05). The reliability and internal consistency of the scales used were assessed using Cronbach Alphas and Confirmatory Factor Analysis (CFA).
Results
Neither males nor females were more at risk for BO. And contrary to what we hypothesised those who recently moved to this nation were not at greater risk for BO (p>0.05). Multivariate analyses showed that younger workers displayed higher burnout scores (p < 0.001).The psychological demand sub-score was positively associated with burnout [ 0.61 (95% CI 0.45 to 0.77), p < 0.001)]. Conversely, decision latitude [-0.33 (95% CI -0.44 to -0.21), p < 0.001)] and support [-0.47 (95% CI -0.60 to -0.35), p < 0.001] were negatively associated with BO.
Those who experienced anxiety or depressive symptoms were respectively more likely to experience burnout [0.30 (95% CI 0.02 to 0.58), p = 0.035 and 0.72 (95% CI 0.41 to 1.02), p < 0.001], with a clear association between higher PHQ-4 scores and risk for burnout (r = 0.619).
Moreover, satisfaction with utilisation of leisure time was inversely related to BO [-0.55 (95% CI -0.68 to –0.41; p < 0.001)]. We could not find any association between number of years worked, profession, marital status and perceived social support and BO, on multivariate anbalysis (p>0.05).
Conclusions
Strress reduction interventions should be made available for all staff, especially addressing those at highest risk for burnout.
Seven kaolins from Georgia (southeastern U.S.A.), ranging from high to low commercial grade, were characterized by X-ray powder diffraction and chemical techniques to establish that the variation in quality was caused by impurities. The Ca and Cs cation-exchange capacities (CEC) varied from 2.67 to 8.17 and from 3.29 to 8.77 meq/100g, respectively. Selective dissolution and correlation analyses strongly indicated that expandable 2:1 minerals, particularly smectite (1.2-5.9%), were responsible for most of the observed variations in Ca CEC (r = 0.85*). The external surface CEC of kaolinite ranged from 0 to 1 meq/ 100 g. The positive significant correlation (r = 0.90**) between the Ca CEC and the K-mica content (03.9%) suggested that Ca CEC may be related to the degree of mica weathering through an expandable mineral stage.
The Cs-retention capacity (0.19–1.14 meq/100 g) was closely related to Cs-measured vermiculite content (r = 0.80*), and this content plus specific surface (R = 0.93**) or mica content (R = 0.86*). The Cs retention appeared to be primarily related to the presence of interlayer wedges at mica/vermiculite XY interfaces.
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.
A method using Li saturation and heating to 250°C to differentiate montmorillonite from beidellite and nontronite has been developed. The test utilizes three washings with 3 M LiCl and two washings with 0.01 M LiCl in 90% methanol to prevent dispersion. An 'infinitely thick’ sample (6–8 mg/cm2) on a glass slide is used to avoid the effects of the reaction of a thin clay film with sodium of the slide when it is heated at 250°C. Solvation with glycerol rather than ethylene glycol is used, because all of the Li smectites studied expanded to some extent in ethylene glycol after the heating. The smectites included several montmorillonites, a nontronite, and saponites. The presence of interstratified montmorillonite and beidellite layers was clearly shown by the test for several smectite samples, including the so-called beidellites from Beidell, Colorado, and Chen-yuan, Taiwan, and several soil clays. The test thereby provides more mineralogical information than the often-used arbitrary dividing point between montmorillonite and beidellite at 50% tetrahedral charge. Heating the Li-saturated clays at 250°C caused substitution of 35 to 125 meq/100 g of nonexchangeable Li. These amounts exceeded the changes in cation-exchange capacity plus Li by 4 to 21 meq/100 g, except for the end-member beidellite from the Black Jack mine, Idaho. Fusion with LiNO3 at 300°C could not be used to differentiate between smectites instead of washing with LiCl solution and heating to 250°C, because fused montmorillonite subsequently expanded to 18 Å with glycerol. Large increases in nonexchangeable Li were caused by the fusion of smectites, a vermiculite, and two partially expanded micas.
Collisionless charged particle motion and its transport in the two-wire model (TWM) with no axial magnetic fields is investigated numerically. The TWM configuration contains a magnetic X-point, and single particle motions in such a field have two conserved quantities: the total kinetic energy and the base field line value which is a quantity derived from the axial canonical momentum. As gyrating particles travel along the field lines, they may reach near the X-point region where the magnetic moment, the first adiabatic invariant, can be occasionally shifted due to a large gradient of the field. When the magnetic moment becomes large, resulting in a large Larmor radius, particles probabilistically cross the X-point to migrate to the opposite side of the TWM configuration. These phenomena are investigated with single particle simulations. We find that the statistical behaviour of the seemingly chaotic magnetic moment shifts are completely determined by the two aforementioned conserved quantities, and also that there exists a threshold energy, determined by the base field line value, allowing only particles with a higher energy to cross the separatrix and migrate. It is found that the crossing time is distributed exponentially, and that the migration confinement time, which is the average crossing time, is shorter for particles with a base field line closer to the separatrix and a higher energy. We provide an empirical expression, derived with the simulations, for estimating the collisionless migration confinement time.
Normothermic Regional Perfusion, or NRP, is a method of donated organ reperfusion using cardiopulmonary bypass or a modified extracorporeal membrane oxygenation (ECMO) circuit after circulatory death while leaving organs in the dead donor’s corpse. Despite its potential, several key ethical issues remain unaddressed by this technology.
Older age is associated with an increase in altruistic behaviors such as charitable giving. However, few studies have investigated the cognitive correlates of financial altruism in older adults. This study investigated the cognitive correlates of financial altruism measured using an altruistic choice paradigm in a community-based sample of older adults.
Participants and Methods:
In the present study, a sample of older adults (N = 67; M age = 69.21, SD = 11.23; M education years = 15.97, SD = 2.51; 58.2% female; 71.6% Non-Hispanic White) completed a comprehensive neuropsychological assessment and an altruistic choice paradigm in which they made decisions about allocating money between themselves and an anonymous person.
Results:
In multiple linear regression analyses that controlled for age, education, and sex, financial altruism was negatively associated with performance on cognitive measures typically sensitive to early Alzheimer’s Disease. These included CVLT-II Short Delay Free Recall (Beta=-0.26, p=0.03); CVLT-II Long Delay Cued Recall (Beta=-0.32, p=0.04), Craft Story 21 Delayed Recall (Beta=-0.32, p=0.01), and Animal Fluency (Beta=-0.27, p=0.02). Findings held when responses were grouped according to how much was given (Gave Equally, Gave More, Gave Less) for word list memory and story memory measures.
Conclusions:
Findings of this study point to a negative relationship between financial altruism and cognitive functioning in older adults on measures known to be sensitive to Alzheimer’s Disease (AD). Findings also point to a potential link between financial exploitation risk and AD in older age.
In recent years, rates of alcohol consumption and alcohol use disorder have steadily increased among adults age 60 and older. Large studies have demonstrated that moderate-to-heavy alcohol consumption (>7 drinks per week) is a risk factor for developing various types of dementias. The effects of alcohol-related problems on cognition are less clear, and are particularly understudied in older adults. Similarly, while there is an established link between worse cognition and financial exploitation vulnerability in older adults, no studies have examined relationships between alcohol-related problems and financial exploitation in this population. The current study therefore explores whether alcohol-related problems are associated with neuropsychological performance and financial exploitation vulnerability in a sample of older adults.
Participants and Methods:
Participants were a community sample of cognitively unimpaired adults over the age of 50 (N = 55, Age M(SD) = 69.1(6.2), 74.5% female, Years of education M(SD) = 16.8(2.3)). Interested individuals were excluded if they reported current or past substance use disorders. Participants completed a laboratory visit that included a neuropsychological assessment. Measures included the NIH Cognition toolbox, CVLT-II, Digit Span, Trails A/B, Benson Complex Figure Recall, and Verbal Fluency: Phonemic and Semantic, from the Alzheimer’s Disease Centers’ Uniform Data Set (UDS) version 3. Participants completed the CAGE Alcohol Abuse Screening Tool and the Short Michigan Alcohol Screener Test - Geriatric Version (SMAST) to assess alcohol-related problems. Both measures are used as clinical screening tools to measure likelihood of a substance use disorder and produce a summary score (0-4 for CAGE, 010 for SMAST) tabulating symptoms of alcohol-related problems. Participants also completed the Perceived Financial Vulnerability Scale (PFVS) to assess financial exploitation vulnerability. As a significant number of participants reported no drinking and therefore no alcohol-related problems, negative binomial regressions were used to test associations between neuropsychological measures, financial exploitation vulnerability, and alcohol-related problems.
Results:
After covarying for age and sex, SMAST was negatively associated with NIH toolbox total cognition (B(SE) = -.14(.07), p<.05) and marginally negatively associated with fluid cognition (B(SE) = -.07(.04), p=.06). Neither SMAST nor CAGE scores were significantly associated with performance on any other neuropsychological test (ps = .13-.99). SMAST was positively associated with financial exploitation vulnerability (B(SE) = .31(.16), p = .05); this effect remained significant after covarying for NIH total composite score in a secondary analysis.
Conclusions:
In a community sample of cognitively unimpaired, low-drinking adults over the age of 50, more alcohol-related problems were associated with worse NIH toolbox cognition scores. Similarly, more alcohol-related problems were associated with greater financial exploitation vulnerability, and this relationship was not driven by worse cognition. These results suggest that even low amounts of drinking and alcohol-related problems may be associated with cognition and financial exploitation vulnerability in cognitively unimpaired older adults. This study also corroborates the use of the SMAST over the CAGE in older adult populations that may be more sensitive to cognitive changes.
Prior work suggests financial exploitation vulnerability may be an early behavioral manifestation of Alzheimer’s disease (AD). Brain morphometric measures of the parahippocampal gyrus and entorhinal cortex have been shown to be sensitive to early AD progression. We hypothesized that perceived financial exploitation vulnerability may be associated with morphometric measures of the parahippocampal gyrus and entorhinal cortex in cognitively unimpaired older adults. We secondarily investigated the association of morphometric measures with neuropsychological measures.
Participants and Methods:
The sample consisted of 39 cognitively unimpaired older adults (mean age = 68.74 ± 6.43, mean education = 16.87 ± 2.35, 77% female). Cognitive impairment was screened using the telephone version of the Montreal Cognitive Assessment (MoCA) and the cut-off was 21 for study participation. Perceived financial exploitation vulnerability was characterized using a 6-item self-report measure derived from the contextual items of the Lichtenberg Financial Rating Scale. Neuropsychological measures included the CVLT-II Long Delay Free Recall (verbal memory), Benson Complex Figure Recall (visual memory), and Verbal Fluency: Phonemic Test from the Alzheimer’s Disease Centers’ Uniform Data Set (UDS) version 3. Brain images were collected on a 7 Tesla Siemens Magnetom with the following parameters: TE=2.95ms, TR=2200ms, 240 sagittal slices, acquired voxel size (avs)=0.7mm x 0.7mm x 0.7mm. Structural brain images were processed using FreeSurfer version 7.2.0. Cortical thickness and volume measures were generated using the Killiany/Desikian parcellation atlas. Regions were averaged across hemispheres to obtain a single value for each region. Volume measures were adjusted for intracranial volume. Bivariate analyses were conducted to assess relationships between each outcome variable and potential confounders (age, sex, and education). Linear regression models were adjusted for any covariates significantly associated with the outcome variable (none for perceived financial exploitation vulnerability; sex and age for verbal memory; education for visual memory; sex for verbal fluency).
Results:
Smaller entorhinal cortex volume (β = -1275.14, SE = 582.79, p < 0.05) and lower parahippocampal gyrus thickness (β = -3.37, SE = 1.57, p < 0.05) were significantly associated with greater perceived financial exploitation vulnerability. Lower entorhinal cortex thickness was marginally associated with greater perceived financial exploitation vulnerability (β = -2.03, SE = 1.11, p = 0.08). Higher parahippocampal gyrus thickness was associated with better verbal fluency (β = 17.66, SE = 7.01, p < 0.05). Higher entorhinal cortex thickness was associated with better visual memory (β = 4.71, SE = 1.73, p < 0.05). No significant associations were observed between structural brain measures and verbal memory.
Conclusions:
These results suggest smaller entorhinal cortex volume and lower parahippocampal gyrus thickness are associated with higher perceived financial exploitation vulnerability in cognitively normal older adults. Additionally, parahippocampal gyrus thickness appears to be associated with verbal fluency abilities while entorhinal cortex thickness appears to be associated with visual memory. Taken together, these findings lend support to the notion that financial exploitation vulnerability may serve as an early behavioral manifestation of preclinical AD. Longitudinal studies are needed to better understand the temporal nature of these relationships.
We explored the utility of the standardized infection ratio (SIR) for surgical site infection (SSI) reporting in an Australian jurisdiction.
Design:
Retrospective chart review.
Setting:
Statewide SSI surveillance data from 2013 to 2019.
Patients:
Individuals who had cardiac bypass surgery (CABG), colorectal surgery (COLO), cesarean section (CSEC), hip prosthesis (HPRO), or knee prosthesis (KPRO) procedures.
Methods:
The SIR was calculated by dividing the number of observed infections by the number of predicted infections as determined using the National Healthcare Safety Network procedure-specific risk models. In line with a minimum precision criterion, an SIR was not calculated if the number of predicted infections was <1.
Results:
A SIR >0 (≥1 observed SSI, predicted number of SSI ≥1, no missing covariates) could be calculated for a median of 89.3% of reporting quarters for CABG, 75.0% for COLO, 69.0% for CSEC, 0% for HPRO, and 7.1% for KPRO. In total, 80.6% of the reporting quarters, when the SIR was not calculated, were due to no observed infections or predicted infections <1, and 19.4% were due to missing covariates alone. Within hospitals, the median percentage of quarters during which zero infections were observed was 8.9% for CABG, 20.0% for COLO, 25.4% for CSEC, 67.3% for HPRO, and 71.4% for KPRO.
Conclusions:
Calculating an SIR for SSIs is challenging for hospitals in our regional network, primarily because of low event numbers and many facilities with predicted infections <1. Our SSI reporting will continue to use risk-indexed rates, in tandem with SIR values when predicted number of SSI ≥1.
Symmetrical Drug-Related Intertriginous and Flexural Exanthema (SDRIFE) is characterised by a distinctive pattern of erythematous and symmetrical rash over the gluteal and intertriginous regions after exposure to certain systemic medications. This is an uncommon condition which has been thought to be due to a Type IV delayed hypersensitivity reaction. Literature on clozapine-induced SDRIFE remains scarce, and reports of cross-reactivity among anti-psychotics are limited as well.
Objectives
To present a clinical case of Clozapine-induced SDRIFE with cross-reactivity between Clozapine and Quetiapine.
Methods
We describe a case of a lady with Treatment Resistant Schizophrenia who developed erythematous lesions with desquamation over her skin fold regions and buttocks within two months of Clozapine initiation.
Results
In our case, the lady was diagnosed with SDRIFE secondary to Clozapine. Clozapine was ceased, and the rashes resolved completely within a week. However, her psychiatric condition continued to worsened and she was trialed on Quetiapine. Unfortunately, she developed angioedema of the lips which necessitated a cessation of Quetiapine.
Conclusions
This case report illustrates the importance of recognising this rare condition, which can be readily treated by withdrawal of the culprit drug. Given that Clozapine and Quetiapine are structurally similar and fall under the class of Dibenzodiazepines, physicians should also be aware of the possibility of cross-reactivity among anti-psychotic medications leading to hypersensitive reactions.
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.
Consumption of probiotics and/or yogurt could be a solution for restoring the balance of the gut microbiota. This study examined associations of regular intake of probiotic supplements or yogurt with the gut microbiota among a diverse population of older adults (N=1,861; 60–72 years). Faecal microbial composition was obtained from 16S rRNA gene sequencing (V1–V3 region). General linear models were used to estimate the associations of probiotic supplement or yogurt intake with microbiome measures adjusting for covariates. Compared to non-yogurt consumers (N=1,023), regular yogurt consumers (≥once/week, N=818) had greater Streptococcus (β=0.29, P=0.0003) and lower Odoribacter (β=−0.33, P<0.0001) abundance. The directions of the above associations were consistent across the five ethnic groups but stronger among Japanese Americans (Streptococcus: β=0.56, P=0.0009; Odoribacter: β=−0.62, P=0.0005). Regular intake of probiotic supplements (N=175) was not associated with microbial characteristics (i.e., alpha diversity and the abundance of 152 bacteria genera). Streptococcus is one of the predominant bacteria genera in yogurt products, which may explain the positive association between yogurt consumption and Streptococcus abundance. Our analyses suggest that changes in Odoribacter were independent of changes in Streptococcus abundance. Future studies may investigate whether these microbial genera and their sub-level species mediate potential pathways between yogurt consumption and health.
Sinonasal inverted papilloma has a high tendency for recurrence, local bone destruction and risk of malignant transformation. Therefore, complete resection of the tumour is required, and close follow up is essential. This article describes the clinical outcomes, recurrence rate and malignant transformation rate of sinonasal inverted papilloma.
Methods
In this study, 139 patients diagnosed with sinonasal inverted papilloma in our hospital from December 2010 to May 2022 were retrospectively analysed. All patients underwent endoscopic surgery.
Results
Sinonasal inverted papilloma occurred more often in males than in females. The mean age of patients with sinonasal inverted papilloma was 67.3 ± 5.7 years at diagnosis. The most prevalent site of origin was the maxillary sinus (50.4 per cent). The recurrence rate was 5.75 per cent, and the malignant transformation rate was 6.5 per cent.
Conclusion
All patients in this study underwent endoscopic surgery. Meticulous resection and regular long-term follow ups are crucial to reducing sinonasal inverted papilloma recurrence after surgery.
