BACKGROUND
Each hospital day of delirium incurs greater healthcare costs, higher levels of care, greater staff burden, and higher complication rates. Accordingly, administrators are incentivized to ...identify models of care that reduce delirium rates and associated costs.
PURPOSE
We present a systematic review and meta‐analysis of delirium prevention models of care.
DATA SOURCES
Ovid MEDLINE, CINAHL, Cochrane Database of Systematic Reviews, EMBASE, and PsycINFO.
STUDY SELECTION
Eligible models of care were defined as provider‐oriented interventions involving revision of professional roles, multidisciplinary teams, and service integration. Included studies implemented multidomain, multicomponent interventions, used a validated delirium instrument, and enrolled a control group to evaluate efficacy or effectiveness.
DATA EXTRACTION
We extracted data on study design; Population, model of care, outcomes, and results.
DATA SYNTHESIS
A total of 15 studies were included. All but two studies reported reduction in delirium or its duration, and 11 studies reported statistically significant improvements. Using random effects models, the pooled odds ratios of delirium incidence were 0.56 (95% CI: 0.37‐0.85) from three randomized controlled trials, 0.63 (95% CI 0.37‐1.07) from four pre–post intervention studies, and 0.79 (95% CI: 0.46‐1.37) from three additional nonrandomized studies.
CONCLUSIONS
Several models of care can prevent delirium. In general, higher quality studies were more likely to demonstrate statistical significance of an effect. The diverse models of care included here explored interventions adapted to specific care settings, especially by addressing setting‐specific delirium risk factors. These care models illustrate a range of promising strategies that deserve growing recognition, refinement, and implementation.
Background Contemporary EUS-guided FNA techniques involve the use of a needle, with an air column within the lumen, with or without suction. We describe a novel technique with an aim to improve the ...quality of the aspirate. Objective To compare a novel “wet suction” technique (WEST) with the conventional FNA technique (CFNAT) of EUS-guided FNA using a 22-gauge FNA needle. Design Prospective, single-blind, and randomized trial. Setting Two large tertiary-care hospitals. Patients All consecutive adult patients presenting for EUS with possible FNA of solid lesions were offered the chance to participate in the study. Methods All lesions were sampled with the same needle by using alternating techniques. Patients were randomized to the WEST versus the CFNAT for the first pass. If the first pass was made with the WEST, the second pass was made with the CFNAT, and subsequent passes were made in an alternating manner by using the same sequence. All FNAs were performed using 22-gauge needles. Main Outcome Measurements Specimen adequacy, cellularity, and blood contamination of EUS-guided FNA aspirates graded on a predefined scale. Results The WEST yielded significantly higher cellularity in a cell block compared with the CFNAT, with a mean cellularity score of 1.82 ± 0.76 versus 1.45 ± 0.768 ( P < .0003). The WEST cell block resulted in a significantly better specimen adequacy of 85.5% versus 75.2% ( P < .035). There was no difference in the amount of blood contamination between the 2 techniques. Limitations Lack of cross check and grading by a second cytopathologist. Conclusion The novel WEST resulted in significantly better cellularity and specimen adequacy in cell blocks of EUS-guided FNA aspirate of solid lesions than the CFNAT.
Summary Background The increase in the worldwide incidence of endometrial cancer relates to rising obesity, falling fertility, and the ageing of the population. Transvaginal ultrasound (TVS) is a ...possible screening test, but there have been no large-scale studies. We report the performance of TVS screening in a large cohort. Methods We did a nested case-control study of postmenopausal women who underwent TVS in the United Kingdom Collaborative Trial of Ovarian Cancer Screening ( UKCTOCS ) following recruitment between April 17, 2001, and Sept 29, 2005. Endometrial thickness and endometrial abnormalities were recorded, and follow-up, through national registries and a postal questionnaire, documented the diagnosis of endometrial cancer. Our primary outcome measure was endometrial cancer and atypical endometrial hyperplasia (AEH). Performance characteristics of endometrial thickness and abnormalities for detection of endometrial cancer within 1 year of TVS were calculated. Epidemiological variables were used to develop a logistic regression model and assess a screening strategy for women at higher risk. Our study is registered with ClinicalTrials.gov , number NCT00058032 , and with the International Standard Randomised Controlled Trial register , number ISRCTN22488978. Findings 48 230 women underwent TVS in the UKCTOCS prevalence screen. 9078 women were ineligible because they had undergone a hysterectomy and 2271 because their endometrial thickness had not been recorded; however, 157 of these women had an endometrial abnormality on TVS and were included in the analysis. Median follow-up was 5·11 years (IQR 4·05–5·95). 136 women with endometrial cancer or AEH within 1 year of TVS were included in our primary analysis. The optimum endometrial thickness cutoff for endometrial cancer or AEH was 5·15 mm, with sensitivity of 80·5% (95% CI 72·7–86·8) and specificity of 86·2% (85·8–86·6). Sensitivity and specificity at a 5 mm or greater cutoff were 80·5% (72·7–86·8) and 85·7% (85·4–86·2); for women with a 5 mm or greater cutoff plus endometrial abnormalities, the sensitivity and specificity were 85·3% (78·2–90·8) and 80·4% (80·0–80·8), respectively. For a cutoff of 10 mm or greater, sensitivity and specificity were 54·1% (45·3–62·8) and 97·2% (97·0–97·4). When our analysis was restricted to the 96 women with endometrial cancer or AEH who reported no symptoms of postmenopausal bleeding at the UKCTOCS scan before diagnosis and had an endometrial thickness measurement available, a cutoff of 5 mm achieved a sensitivity of 77·1% (67·8–84·3) and specificity of 85·8% (85·7–85·9). The logistic regression model identified 25% of the population as at high risk and 39·5% of endometrial cancer or AEH cases were identified within this high risk group. In this high-risk population, a cutoff at 6·75 mm achieved sensitivity of 84·3% (71·4–93·0) and specificity of 89·9% (89·3–90·5). Interpretation Our findings show that TVS screening for endometrial cancer has good sensitivity in postmenopausal women. The burden of diagnostic procedures and false-positive results can be reduced by limiting screening to a higher-risk group. The role of population screening for endometrial cancer remains uncertain, but our findings are of immediate value in the management of increased endometrial thickness in postmenopausal women undergoing pelvic scans for reasons other than vaginal bleeding.

Among a sample of women who sell sex (WSS), we examined unmet health needs, resources for telehealth, utilization interest, and attributes associated with interest in using telehealth.
Explanatory ...sequential mixed methods.
WSS (N = 52) completed a fixed choice survey and focus group (N = 6, 26 individuals) from drop-in centers serving WSS. Chi-square/t-tests and results from the survey data informed the semi-structured focus group interview guide. Thematic analysis of focus group data was conducted to identify themes.
Over half (58 %) of participants expressed interest in using telehealth; however, some lack the necessary resources for use. While 60 % of participants own mobile phones and 46 % have access to a computer, only 35 % have a secure, private space for telehealth appointments. Interest in telehealth was higher among participants who self-identified as having high risk for HIV compared to low risk for HIV (79 % versus 46 %, p = 0.024), and among those considering PrEP for HIV prevention versus not considering PrEP (68 % versus 32 %, p = 0.046). Focus group participants preferred face-to-face encounters for complex medical concerns but expressed interest in telehealth for improved access to healthcare providers for routine care and mental health.
Incorporating telehealth into community organizations could be one strategy to address health inequities experienced by WSS. Access to resources, including technology and safe spaces may be well-accepted if offered at trusted community organizations. Such accessibility addresses a gap in care for WSS and paves the way for new avenues for HIV prevention, mental health support, and research related to unmet health needs among WSS.
The COVID-19 pandemic has placed an enormous and growing burden on the population and health infrastructure, warranting innovative ways to mitigate risk of contracting and developing severe forms of ...this disease. A growing body of literature raises the issue of vitamin C and vitamin D as a risk-assessment tool, and therapeutic option, in COVID-19.
The objective of this pilot study was to measure serum vitamin C and vitamin D levels in a cohort of patients with critical COVID-19 illness in our community hospital ICU, correlate with other illness risk factors (age, BMI, HgbA1c, smoking status), generate hypotheses, and suggest further therapeutic intervention studies.
This pilot study included all 21 critically ill COVID-19 patients hospitalized in May 2020 in the ICU of North Suburban Medical Center, Thornton, Colorado, in whose care the principal investigator (C.A.) was involved. We measured patients’ serum vitamin C and vitamin D levels, and standard risk factors like age, BMI, HbA1c, and smoking status. Variables in this study were gauged using descriptive statistics.
Of 21 critically ill COVID-19 patients (15 males and 6 females, 17 Hispanic and 4 Caucasian, of median age 61 years, range 20–94), there were 11 survivors.
Serum levels of vitamin C and vitamin D were low in most of our critically ill COVID-19 ICU patients.
Older age and low vitamin C level appeared co-dependent risk factors for mortality from COVID-19 in our sample.
Insulin resistance and obesity were prevalent in our small cohort, but smoking was not.
Our pilot study found low serum levels of vitamin C and vitamin D in most of our critically ill COVID-19 ICU patients. Older age and low vitamin C level appeared co-dependent risk factors for mortality. Many were also insulin-resistant or diabetic, overweight or obese, known as independent risk factors for low vitamin C and vitamin D levels, and for COVID-19.
These findings suggest the need to further explore whether caring for COVID-19 patients ought to routinely include measuring and correcting serum vitamin C and vitamin D levels, and whether treating critically ill COVID-19 warrants acute parenteral vitamin C and vitamin D replacement.

Background
Obesity management in young women necessitates interventions that include dietary modification and physical exercise. High-intensity lifestyle modification is effective in managing obesity ...in young women.
Objectives
The study determined the effectiveness of a nurse-led lifestyle modification intervention (NLLMI) on obesity among young women in India.
Methods
The study adopted a quasi-experimental pre- and post-interventional control group research design. The study was conducted among obese young women in the communities of Jabalpur, Madhya Pradesh, India. The participants were selected using convenient sampling technique. The sample included 150 women in the study group and 150 in the control group. The NLLMI comprising of exercises and dietary modifications were taught to the participants for 30 min three times a week for 24 weeks. Thereafter, they were encouraged to follow the diet and perform the exercises on their own for the next 12 weeks. Practice diary was maintained by the participants and they were encouraged to continue the intervention through the phone. The participants in the control group did not engage in the NLLMI until the post-test. However, they did receive the same NLLMI after the trial was over.
Results
There was a high statistically significant difference (p = 0.001) between the study group and the control group the after 12th and 24th weeks of NLLMI. The study group had a significant reduction in BMI after the intervention.
Conclusions
Young obese women may benefit from a NLLMI if they regularly follow the healthy eating habits and physical exercise.
Summary Background Rotavirus is the most common cause of severe dehydrating gastroenteritis in developing countries. Safe, effective, and affordable rotavirus vaccines are needed in these countries. ...We aimed to assess the efficacy and tolerability of a monovalent human-bovine rotavirus vaccine for severe rotavirus gastroenteritis in low-resource urban and rural settings in India. Methods We did a randomised double-blind, placebo-controlled, multicentre trial at three sites in Delhi (urban), Pune (rural), and Vellore (urban and rural) between March 11, 2011, and Nov 5, 2012. Infants aged 6–7 weeks were randomly assigned (2:1), via a central interactive voice or web response system with a block size of 12, to receive either three doses of oral human-bovine natural reassortant vaccine (116E) or placebo at ages 6–7 weeks, 10 weeks, and 14 weeks. Infants' families, study investigators, paediatricians in referral hospitals, laboratory staff, and committee members were all masked to treatment allocation. The primary outcome was incidence of severe rotavirus gastroenteritis (≥11 on the Vesikari scale). Efficacy outcomes and adverse events were ascertained through active surveillance. Analysis was by intention to treat and per protocol. The trial is registered with Clinical Trial Registry–India (CTRI/2010/091/000102) and ClinicalTrials.gov ( NCT01305109 ). Findings 4532 infants were assigned to receive the 116E vaccine and 2267 to receive placebo, of whom 4354 (96%) and 2187 (96%) infants, respectively, were included in the primary per-protocol efficacy analysis. 71 events of severe rotavirus gastroenteritis were reported in 4752 person-years in infants in the vaccine group compared with 76 events in 2360 person-years in those in the placebo group; vaccine efficacy against severe rotavirus gastroenteritis was 53·6% (95% CI 35·0–66·9; p=0·0013) and 56·4% (36·6–70·1; p<0·0001) in the first year of life. The number of infants needed to be immunised to prevent one severe rotavirus gastroenteritis episode was 55 (95% CI 37–97). The incidence of severe rotavirus gastroenteritis per 100 person-years was 1·5 in the vaccine group and 3·2 in the placebo group, with an incidence rate ratio of 0·46 (95% CI 0·33–0·65). Prevalence of immediate, solicited, and serious adverse events was similar in both groups. One case of urticaria in the vaccine group and one each of acute gastroenteritis and suspected sepsis in the placebo group were regarded as related to the study product. We recorded six cases of intussusception in the vaccine group and two in the placebo group, all of which happened after the third dose. 25 (<1%) infants in the vaccine group and 17 (<1%) in the placebo group died; no death was regarded as related to the study product. Interpretation Monovalent human-bovine (116E) rotavirus vaccine is effective and well tolerated in Indian infants.

Summary Background Ovarian cancer has a high case–fatality ratio, with most women not diagnosed until the disease is in its advanced stages. The United Kingdom Collaborative Trial of Ovarian Cancer ...Screening (UKCTOCS) is a randomised controlled trial designed to assess the effect of screening on mortality. This report summarises the outcome of the prevalence (initial) screen in UKCTOCS. Methods Between 2001 and 2005, a total of 202 638 post-menopausal women aged 50–74 years were randomly assigned to no treatment (control; n=101 359); annual CA125 screening (interpreted using a risk of ovarian cancer algorithm) with transvaginal ultrasound scan as a second-line test (multimodal screening MMS; n=50 640); or annual screening with transvaginal ultrasound (USS; n=50 639) alone in a 2:1:1 ratio using a computer-generated random number algorithm. All women provided a blood sample at recruitment. Women randomised to the MMS group had their blood tested for CA125 and those randomised to the USS group were sent an appointment to attend for a transvaginal scan. Women with abnormal screens had repeat tests. Women with persistent abnormality on repeat screens underwent clinical evaluation and, where appropriate, surgery. This trial is registered as ISRCTN22488978 and with ClinicalTrials.gov , number NCT00058032. Findings In the prevalence screen, 50 078 (98·9%) women underwent MMS, and 48 230 (95·2%) underwent USS. The main reasons for withdrawal were death (two MMS, 28 USS), non-ovarian cancer or other disease (none MMS, 66 USS), removal of ovaries (five MMS, 29 USS), relocation (none MMS, 39 USS), failure to attend three appointments for the screen (72 MMS, 757 USS), and participant changing their mind (483 MMS, 1490 USS). Overall, 4355 of 50 078 (8.7%) women in the MMS group and 5779 of 48 230 (12·0%) women in the USS group required a repeat test, and 167 (0·3%) women in the MMS group and 1894 (3·9%) women in the USS group required clinical evaluation. 97 of 50 078 (0·2%) women from the MMS group and 845 of 48 230 (1·8%) from the USS group underwent surgery. 42 (MMS) and 45 (USS) primary ovarian and tubal cancers were detected, including 28 borderline tumours (eight MMS, 20 USS). 28 (16 MMS, 12 USS) of 58 (48·3%; 95% CI 35·0–61·8) of the invasive cancers were stage I/II, with no difference (p=0·396) in stage distribution between the groups. A further 13 (five MMS, eight USS) women developed primary ovarian cancer during the year after the screen. The sensitivity, specificity, and positive-predictive values for all primary ovarian and tubal cancers were 89·4%, 99·8%, and 43·3% for MMS, and 84·9%, 98·2%, and 5·3% for USS, respectively. For primary invasive epithelial ovarian and tubal cancers, the sensitivity, specificity, and positive-predictive values were 89·5%, 99·8%, and 35·1% for MMS, and 75·0%, 98·2%, and 2·8% for USS, respectively. There was a significant difference in specificity (p<0·0001) but not sensitivity between the two screening groups for both primary ovarian and tubal cancers as well as primary epithelial invasive ovarian and tubal cancers. Interpretation The sensitivity of the MMS and USS screening strategies is encouraging. Specificity was higher in the MMS than in the USS group, resulting in lower rates of repeat testing and surgery. This in part reflects the high prevalence of benign adnexal abnormalities and the more frequent detection of borderline tumours in the USS group. The prevalence screen has established that the screening strategies are feasible. The results of ongoing screening are awaited so that the effect of screening on mortality can be determined.
