RESUMO
BACKGROUND: A recent controversy in vitamin D research is a "U-shaped association", with elevated disease risks at both high and low 25-hydroxyvitamin D (25 (OH) D) levels. METHODS: This is a cross-sectional study of 238 male nursing home veterans in Hawaii. Classification and regression tree (CART) analysis identified groups based on 25 (OH) D and vitamin D supplementation for frailty risk. Characteristics were examined and compared across the groups using logistic regression and receiver operating characteristic (ROC) curve analyses. RESULTS: CART analysis identified three distinct groups: vitamin D supplement users (n = 86), non-users with low vitamin D (n = 55), and non-users with high vitamin D (n = 97). Supplement users were the most frail, but had high mean 25 (OH) D of 26.6 ng/mL, which was compatible with 27.1 ng/mL in non-users with high vitamin D, while mean 25 (OH) D of non-users with low vitamin D was 11.7 ng/mL. Supplement users and non-users with low vitamin D were significantly more likely to be frail (odds ratio (OR) = 9.90, 95% CI = 2.18-44.86, p = 0.003; OR = 4.28, 95% CI = 1.44-12.68, p = 0.009, respectively), compared with non-users with low vitamin D. ROC curve analysis showed the three groups significantly predicted frailty (area under the curve = 0.73), with sensitivity of 64.4% and specificity of 76.7%, while 25 (OH) D did not predict frailty. CONCLUSIONS: In these nursing home veterans, vitamin D supplement users were the most frail but with high 25 (OH) D. This can potentially be a cause of U-shaped associations between vitamin D levels and negative health outcomes.

Anisakiasis, a parasitic infection by larvae of the nematode Anisakis found in raw or undercooked saltwater fish, mostly involves stomach but rarely small intestine. We report a rare case of a 61-year-old man who presented with abdominal pain and developed small bowel obstruction caused by intestinal anisakiasis. Abdominal computed tomography revealed segmental edema of the intestinal wall with proximal dilatation. The patient underwent urgent laparotomy because strangulated small bowel obstruction was suspected. A localized portion of the intestine around jejunoileal junction was found to be erythematous, edematous, and hardened, which was resected. The resected specimen showed a linear whitish worm, Anisakis simplex, penetrating into the intestinal mucosa. It is often clinically challenging to consider intestinal anisakiasis in the differential diagnosis because of its nonspecific abdominal symptoms and findings. Although gastrointestinal anisakiasis is still rare in the United States, the incidence is expected to rise given the growing popularity of Japanese cuisine such as sushi or sashimi. Anisakiasis should be considered as one of the differential diagnoses in patients with nonspecific abdominal symptoms after consumption of raw or undercooked fish.

OBJECTIVES: Older adults may be at increased risk of loneliness. Frailty is also common in older adults, however, associations between loneliness and frailty have been understudied. This systematic review and meta-analysis aimed to explore evidence on how loneliness and frailty are correlated. METHODS: A systematic search of the literature was conducted using 4 electronic databases in February 2022 for any studies published in 2000 or later that provided cross-sectional or longitudinal associations between loneliness and physical frailty in community-dwelling older adults. A meta-analysis was attempted to combine data when possible. RESULTS: From 1386 studies identified by the initial search, 16 studies were included for this review. Standardized mean difference (SMD) meta-analysis based on mean loneliness score across 3 frailty groups provided by 6 cross-sectional studies showed that worse frailty status was significantly associated with a higher degree of loneliness (SMD between frail and robust, frail and prefrail, and prefrail and robust were 0.77 (95% confidence interval (CI)= 0.57-0.96), 0.37 (95%CI=0.25-0.50), and 0.30 (95%CI=0.20-0.40), respectively.) Meta-analyses combining cross-sectional data from 6 studies revealed that frailty was significantly associated with a higher risk of loneliness compared with robustness (3 studies: pooled OR=3.51, 95%CI=2.70-4.56 for frailty, pooled OR=1.88, 95%CI=1.57-2.25 for prefrailty) and compared with non-frailty (4 studies: pooled OR=2.05, 95%CI=1.76-2.39). A meta-analysis involving two longitudinal studies showed that baseline loneliness was associated with a significantly higher risk of worsening frailty (2 studies: pooled OR=1.41, 95%CI=1.16-1.72). CONCLUSIONS: This systematic review and meta-analysis was the first, to our knowledge, to quantitatively demonstrate significant cross-sectional and longitudinal associations between loneliness and frailty in community-dwelling older adults.

OBJECTIVES: To provide the first report on prevalence of vitamin D deficiency in newly admitted nursing home (NH) residents and associations with functional disabilities and chronic diseases. DESIGN: Retrospective chart review. SETTING: Nursing home (NH). PARTICIPANTS: Male veterans newly admitted to a NH for rehabilitation, skilled-nursing care, intermediate care, or respite care between January 2011 and June 2012. MEASUREMENTS: Total serum 25-hydroxyvitamin D (25(OH)D) levels were measured on admission. Vitamin D supplement users and those without 25(OH)D measurement within 7 days of admission were excluded, leaving an analytical sample of 104 residents. Vitamin D deficiency was defined as 25(OH)D less than 20 ng/mL. Data were collected on age, ethnicity, season, body mass index (BMI), functional disability in activities of daily living (ADLs) (mobility, bathing, dressing, toileting, continence, and feeding), and prevalent chronic diseases. RESULTS: Prevalence of vitamin D deficiency was 49.0%. In multivariate logistic regression models adjusted for age, ethnicity, and BMI, vitamin D deficiency was significantly associated with number of ADL disabilities (odds ratio (OR) = 1.4 for each 1-point increase in ADL disability score, P = .03) and prevalent diabetes mellitus (OR = 3.0, P = .03). In regression models using each ADL disability as a separate variable, only disability in feeding (OR = 4.7, P = .05) and diabetes mellitus (OR = 2.9, P = .04) remained significant. CONCLUSION: Almost half the individuals entering the NH and not taking vitamin D supplements had vitamin D deficiency. Greater number of ADL disabilities, disability in feeding, and prevalent diabetes mellitus were independently associated with vitamin D deficiency.

Place of death is an indicator of health service utilization at the end of life and differs according to cause of death. Asian Americans may have a higher percentage of hospital deaths than Caucasian Americans, yet reasons for this finding are unclear. This study examined distribution of place of death and the associations between place and cause of death in elderly Japanese-American men in a longitudinal cohort: the Honolulu Heart Program and Honolulu-Asia Aging Study. Data collected between 1991 and 1999 on 1,352 men aged 73 to 99 at death were analyzed for associations between cause-of-death characteristics and hospital, home, or nursing home location of death. Fifty-nine percent of men died in hospitals, 23% died at home, and 18% died in nursing homes. Of the dementia-related deaths, 43% occurred in hospitals (vs 16% in a national study), 37% occurred in nursing homes (vs 67% in a national study), and 20% occurred at home. Of the stroke deaths, 53% occurred in hospitals, 40% were in nursing homes, and 7% occurred at home. Of the cancer deaths, 53% occurred in hospitals, 34% occurred at home, and 13% were in nursing homes. Traditional family obligation to care for elderly people at home and inability to access care for dementia may account for the greater rate of hospital death and lower rate of nursing home deaths in this cohort. Attitudes of elderly Japanese Americans and their families regarding place of care at the end of life, particularly in the setting of dementia, merit future study.

We redesigned our medical school's Problem-Based Learning (PBL) curriculum to include a substantial increase in required geriatrics content. Innovations included new PBL health care problems and standardized patients (SPs) throughout the first three years and a new required four-week, fourth-year rotation. We used data from the AAMC Medical School Graduation Questionnaire, the UCLA Geriatrics Knowledge Test and Attitudes Survey and a Geriatrics SP Examination to measure self-efficacy, geriatrics specific knowledge, attitudes and clinical skills before and after these curricular changes. Positive effects on students' self-efficacy, knowledge and skills were demonstrated. Scores on the attitude scale were high before and after implementation. The demonstration of improved educational outcomes will help to validate our curricular changes and guide their future development.
