RESUMO
BACKGROUND: Reverse shoulder arthroplasty (RSA) is a well-recognized treatment for many shoulder conditions, including rotator cuff arthropathy, primary glenohumeral joint arthritis, and rheumatoid arthritis, and can be used in both trauma and revision settings. Over the past 10 years, its popularity in New Zealand has been increasing, with a 6%-7% annual growth rate during this period. Stemless RSA designs have the following proposed advantages: They can preserve humeral bone stock, they can limit periprosthetic fractures, and they can be indicated in patients with abnormal diaphyseal humeral anatomy. To date, only 1 study has evaluated the outcomes of the Lima SMR Stemless implant. We present our data with an aim to report how the stemless reverse arthroplasty compares to a conventional stemmed implant. METHODS: We performed a retrospective review of a consecutive series of patients treated at a single institution between 2015 and 2020. The endpoint was defined as final follow-up at a minimum of 2 years. Patients were excluded from the final analysis if they underwent revision. Thirty-three patients were identified as having undergone stemless RSA. Thirty patients had patient-reported outcome measures and radiographs at a minimum of 2 years' follow-up. Three patients had undergone revision within 2 years. The same sample size of stemmed RSAs (n = 33) was selected for comparison. RESULTS: A total of 60 patients were included in the final analysis, of whom 30 underwent stemless RSA and 30 underwent stemmed RSA. The demographic characteristics of the 2 groups were comparable except age at operation, which showed a statistically significant difference (P = .001): 77 years (stemmed) vs. 65 years (stemless). The mean Oxford Shoulder Score was 40.1 in the stemless group vs. 40 in the stemmed group. The mean American Shoulder and Elbow Surgeons score was 72.9 in the stemless group vs. 79 in the stemmed group. Patient-reported outcome measures, pain scores, and satisfaction ratings were not statistically significantly different between the 2 groups. In terms of radiographic data, subsidence was observed in 2 patients in the stemless RSA group but the patients had no clinical symptoms. Also in the stemless RSA group, 1 patient had an acromial stress fracture and 1 patient had a superficial wound infection successfully treated with oral antibiotics. In terms of revisions in the stemless RSA group, 1 patient underwent revision owing to chronic infection, 1 underwent revision as a result of a periprosthetic fracture after a fall, and 1 underwent revision for gross instability. CONCLUSIONS: The early results of sRSA are promising, and the stemless implant shows similar outcomes to a conventional stemmed implant.

The aim of this qualitative inquiry was to explore older New Zealanders perspectives and experiences of food and nutrition intake, to gain insights to factors that influence vulnerability to malnutrition risk at older age. Participants represented an ethnically diverse group of nutritionally vulnerable older adults (five malnourished and nine at risk), with most participants identifying as having an illness severity of moderate or severe. Thematic content analysis was performed using an integrated approach and took into account participants' nutritional status as determined using the Mini Nutritional Assessment-Short Form. Six key themes emerged. Almost all participants reported they had reduced their food intake and felt that eating less, was the 'logical' thing to do as they were now undertaking less physical activity. They described eating as a chore; they ate because they 'had to keep going', but hardly ever felt hungry (low appetite); they had lost interest in eating, and no longer found food fanciful. Being in the company of others encouraged eating except in stressful situations such as caring for an ill spouse. They had a preference for foods they had grown up with but could no longer readily access or needed to avoid some foods because of coexisting conditions or illnesses, food intolerance and chewing difficulties. Finally, participants tried to eat foods best for their health. The notion of healthy eating as consuming "more vegetables" was widely held, with some participants explaining this meant "less fat and less sugar". Overall, the low food intake reported by these participants appears shaped by a myriad of sociocultural and health related factors. The findings can be used as a foundation to develop strategies for preventing vulnerability to malnutrition with advancing age.

BACKGROUND: Although high protein diets have been tested in controlled environments for applications to weight management, it is not understood if adding high protein foods to the diet would impact ad libitum energy balance in the absence of other lifestyle changes. METHODS: This double-blinded randomized crossover trial compared the effects of a protein shake (PS) to a carbohydrate shake (CS), consumed prior to each major meal to equate to 20% of total energy needs over the course of the day, on energy balance over two 5-day treatment periods in healthy adults with BMI 20-30 kg/m2. Tri-axial accelerometers estimated physical activity energy expenditure. Ad libitum energy intake was measured in a laboratory kitchen. RESULTS: Energy balance was positive during both treatment periods but was not different between periods. There were no interactions between treatment and preload caloric dose or treatment and BMI status on energy balance. Satiety ratings did not differ for any pairwise comparisons between treatment and caloric dose. Controlling for gender and basal metabolic rate, thermic effect of food was greater for PS than CS. CONCLUSIONS: Preload periods significantly altered the macronutrient composition of the overall diet. This study found limited evidence that carbohydrate or protein preloads have differential effects on energy balance in short-term ad libitum settings. TRIAL REGISTRATION: This trial was pre-registered on clinicaltrials.gov as NCT02613065 on 11/30/2015.

BACKGROUND: Malnutrition in patients admitted to hospital may have detrimental effects on recovery and healing. Malnutrition is preceded by a state of malnutrition risk, yet malnutrition risk is often not detected during admission. The aim of the current study was to investigate the magnitude and potential predictors of malnutrition risk in older adults, at hospital admission. METHODS: A cross-sectional was study conducted in 234 older adults (age ≥ 65 or ≥ 55 for Maori or Pacific ethnicity) at admission to hospital in Auckland, New Zealand. Assessment of malnutrition risk status was performed using the Mini Nutritional Assessment Short-Form (MNA®-SF), dysphagia risk by the Eating Assessment Tool (EAT-10), muscle strength by hand grip strength and cognitive status by the Montreal Cognitive Assessment (MoCA) tool. RESULTS: Among 234 participants, mean age 83.6 ± 7.6 years, 46.6% were identified as at malnutrition risk and 26.9% malnourished. After adjusting for age, gender and ethnicity, the study identified [prevalence ratio (95% confidence interval)] high dysphagia risk [EAT-10 score: 0.98 (0.97-0.99)], low body mass index [kg/m2: 1.02 (1.02-1.03)], low muscle strength [hand grip strength, kg: 1.01 (1.00-1.02)] and decline in cognition [MoCA score: 1.01 (1.00-1.02)] as significant predictors of malnutrition risk in older adults at hospital admission. CONCLUSION: Among older adults recently admitted to the hospital, almost three-quarters were malnourished or at malnutrition risk. As the majority (88%) of participants were admitted from the community, this illustrates the need for routine nutrition screening both at hospital admission and in community-dwelling older adults. Factors such as dysphagia, unintentional weight loss, decline in muscle strength, and poor cognition may indicate increased risk of malnutrition.

BACKGROUND: Reverse shoulder arthroplasty is gaining popularity owing to its proven longevity and good outcome scores. Scapular notching remains a concern. This study aimed to assess the safety of larger polyethylene glenospheres with increased eccentricity in comparison with the more conventional metal bearings. The secondary effects on scapular notching, clinical outcomes, range of movement, and complications were also analyzed. METHODS: We conducted a 10-year retrospective review of 145 SMR reverse shoulder arthroplasties (LimaCorporate, Udine, Italy) in 132 patients with radiographs at a minimum of 2 years postoperatively. The primary outcome measure was the survivorship of the larger polyethylene glenospheres. Secondary outcomes were the presence and size of notching, subjective satisfaction score, American Shoulder and Elbow Surgeons score, Oxford Shoulder Score, range of motion, and shoulder-related complications. RESULTS: No failures of the polyethylene glenospheres were noted in the 10-year period. At a minimum of 2 years' follow-up, notching was noted in 16 (25%) of the metal glenospheres vs. 9 (11.1%) of the polyethylene glenospheres (P = .028). The mean Oxford Shoulder Score was lower for the metal glenospheres (P = .005). Range of motion, complications, and overall satisfaction were similar in both groups. CONCLUSION: The inverted bearing configuration demonstrated no failures at a minimum of 2 years' follow-up. A larger study is required to determine whether the decreased incidence and size of early notching are related to the bearing size or material.
RESUMO
INTRODUCTION Malnutrition is an under-recognised and under-treated problem often affecting older adults. AIM The aim of this study was to evaluate the prevalence of and factors associated with malnutrition and frailty among older adults at early admission to residential aged care. METHODS A cross-sectional study was undertaken among eligible older adults within the first week of admission to residential aged care. Participants were assessed for malnutrition risk using the Mini Nutritional Assessment Short Form, frailty using the Fried phenotype criterion, muscle strength using a grip strength dynamometer and gait speed using a 2.4-m walk test. A Cox regression analysis was conducted to identify factors associated with malnutrition risk and frailty status. RESULTS Of 174 participants (mean age 85.5 years, 61% women), two-thirds (66%) were admitted to residential aged care from the community. Most (93%) were either malnourished (48%) or at risk of malnutrition (45%). A total of 76% of participants were frail and 24% were pre-frail. Forty-three percent were both malnourished and frail. Low risk of malnutrition was associated with increases in muscle strength [0.96 (0.93-0.99)], gait speed [0.27 (0.10-0.73)] and pre-frailty status [0.32 (0.12-0.83)]. DISCUSSION This study provides preliminary evidence for high prevalence of malnutrition and frailty at admission to residential aged care. Almost all participants were malnourished or at nutrition risk. Findings highlight the need for strategies to prevent, detect and treat malnutrition in community health care and support nutrition screening at admission to residential aged care.

OBJECTIVE: To investigate the associations between nutrition risk status, body composition and physical performance among community-dwelling older New Zealanders. METHODS: This cross-sectional study enrolled 257 community-dwelling older adults (median age 79 years). Assessments included the Mini Nutritional Assessment-Short Form (MNA®-SF) for nutrition risk; the Eating Assessment Tool-10 for dysphagia risk; bioimpedance analysis for body composition (free fat mass (FFM) and percentage body fat) and gait speed for physical performance. A multiple logistics regression analysis was conducted, to determine factors associated with lower odds [OR (95% CI)] for nutrition risk. RESULTS: Every yearly increase in age was associated with higher odds 1.09 (1.01-1.17) for nutrition risk. Additionally, nutrition risk was less likely to occur among participants of age <85 years 0.30 (0.11-0.79), with no dysphagia 0.29 (0.09-0.97) and those with a healthy gait speed 0.29 (0.09-0.97). Lower odds for nutrition risk were also found with increasing values of FFM index 0.51 (0.34-0.77), and percentage body fat 0.81 (0.72-0.90). Gait speed was positively correlated with FFM index (r=0.19 p<0.022), percentage body fat (r=0.23, p=0.006) and BMI (r=0.29, p<0.001). CONCLUSION: Among these participants, associations between nutrition risk, body composition and physical performance were found. Implications for public health: Routine screening of nutrition risk and/or physical performance among vulnerable older adults is key towards identifying those in need of assessment and dietary intervention. Alongside strategies to encourage physical activity, this may help to slow losses of FFM and protect physical performance.
