Association between tissue loss type and amputation risk among Medicare patients with concomitant diabetes and peripheral arterial disease.

OBJECTIVE: Prior studies have described risk factors associated with amputation in patients with concomitant diabetes and peripheral arterial disease(DM/PAD). However, the association between the severity and extent of tissue loss type and amputation risk remains less well-described. We aimed to quantify the role of different tissue loss types in amputation risk among patients with DM/PAD, in the context of demographic, preventive, and socioeconomic factors. METHODS: Applying ICD-9 and ICD-10 codes to Medicare claims data(2007-2019), we identified all patients with continuous fee-for-service Medicare coverage diagnosed with DM/PAD. Eight tissue loss categories were established using ICD-9 and ICD-10 diagnosis codes, ranging from lymphadenitis(least severe) to gangrene(most severe). We created a Cox proportional hazards model to quantify associations between tissue loss type and one- and five-year amputation risk, adjusting for age, race/ethnicity, sex, rurality, income, comorbidities, and preventive factors. Regional variation in DM/PAD rates and risk-adjusted amputation rates was examined at the hospital referral region(HRR) level. RESULTS: We identified 12,257,174 patients with DM/PAD(48% male, 76% White, 10% prior myocardial infarction, 30% chronic kidney disease). While 2.2 million patients(18%) had some form of tissue loss, 10.0 million patients(82%) did not. The one-year crude amputation rate(major and minor) was 6.4% in patients with tissue loss, and 0.4% in patients without tissue loss. Among patients with tissue loss, one-year any amputation rate varied from 0.89% for patients with lymphadenitis to 26% for patients with gangrene. One-year amputation risk varied from two-fold for patients with lymphadenitis(aHR 1.96, 95%CI 1.43-2.69) to 29-fold for patients with gangrene(aHR 28.7, 95%CI 28.1-29.3), compared to patients without tissue loss. No other demographic variable including age, sex, race, or region incurred a hazard ratio for one- or five-year amputation risk higher than the least severe tissue loss category. Results were similar across minor and major amputation, and one- and five-year amputation outcomes. At a regional level, higher DM/PAD rates were inversely correlated with risk-adjusted five-year amputation rates(R2=0.43). CONCLUSION: Among 12 million patients with DM/PAD, the most significant predictor of amputation was presence and extent of tissue loss, with an association greater in effect size than any other factor studied. Tissue loss could be used in awareness campaigns as a simple marker of high-risk patients. Patients with any type of tissue loss require expedited wound care, revascularization as appropriate, and infection management to avoid amputation. Establishing systems of care to provide these interventions in regions with high amputation rates may prove beneficial for these populations.

Systematic Review Assessing Quality of the Survey Literature in Surgery.

INTRODUCTION: The use of survey methodology in surgical research has proliferated in recent years, but the quality of these surveys and of their reporting is understudied. METHODS: We conducted a comprehensive review of surgical survey literature (January 2022-July 2023) via PubMed in July 2023. Articles which (1) reported data gleaned from a survey, (2) were published in an English language journal, (3) targeted survey respondents in the United States or Canada, and (4) pertained to general surgery specialties were included. We assessed quality of survey reports using the Checklist for Reporting Of Survey Studies (CROSS) guidelines. Articles were evaluated for concordance with CROSS using a dichotomous (yes or no) scale. RESULTS: Initial literature search yielded 481 articles; 57 articles were included in analysis based on the inclusion criteria. The mean response rate was 37% (range 0.62%-98%). The majority of surveys were administered electronically (n = 50, 87.8%). No publications adhered to all 40 CROSS items; on average, publications met 61.2% of items applicable to that study. Articles were most likely to adhere to reporting criteria for title and abstract (mean adherence 99.1%), introduction (99.1%), and discussion (92.4%). Articles were least adherent to items related to methodology (42.6%) and moderately adherent to items related to results (76.6%). Only five articles cited CROSS guidelines or another standardized survey reporting tool (10.5%). CONCLUSIONS: Our analysis demonstrates that CROSS reporting guidelines for survey research have not been adopted widely. Surveys reported in surgical literature may be of variable quality. Increased adherence to guidelines could improve development and dissemination of surveys done by surgeons.

Limb girdle muscular dystrophy R12 (LGMD 2L, anoctaminopathy) mimicking idiopathic inflammatory myopathy: key points to prevent misdiagnosis.

OBJECTIVES: Diagnosing the idiopathic inflammatory myopathies (IIMs) can be challenging as several conditions, including genetic myopathies such as limb girdle muscular dystrophy type R12 (LGMD 2 l, anoctaminopathy) mimic the presentation. Here we describe learning points identified from review of four patients with LGMD 2 l who were initially incorrectly diagnosed with IIM. Our aim is to provide clinicians working in adult rheumatology services with a toolkit to help identify non-inflammatory presentations of myopathy. METHODS: We performed retrospective review of medical notes, laboratory results, muscle imaging and histological findings of four patients with LGMD 2 l who were previously misdiagnosed with IIM. We focussed on clinical presentation and progression, therapeutic agents used and events leading to revision of the diagnosis. RESULTS: Three male patients and one female patient with a mean age of 51 years at presentation were reviewed. In each case, treatment with immunosuppressants, in one case for >15 years, was observed without a clear therapeutic response. All patients were negative for anti-nuclear antibodies and available myositis-associated/specific autoantibodies and associated connective tissue disease features were absent. Prominent fatty infiltration and selective muscle involvement on thigh MRI was found in common. CONCLUSIONS: Adult-onset genetic myopathies, particularly LGMD R12, can mimic IIM. Accurate diagnosis is crucial to avoid the use of potentially harmful immunosuppressive therapies, to allow appropriate genetic counselling and to facilitate involvement in research studies.

The Relationship Between Neonatal Surgery, Postpartum Depression, and Infant Clinical Course.

OBJECTIVE: Postpartum depression (PPD) affects 10-15% of mothers in the general population, and studies show increased incidence for mothers of infants with serious health conditions. This study investigates incidence of PPD in mothers of surgical patients in the neonatal intensive care unit (NICU) and characterizes these patients' clinical and neurodevelopmental outcomes. METHODS: This retrospective cohort study analyzed Nebraska's Tracking Infant Progress Statewide (TIPS) database and referring hospital medical records from February 2013 to June 2018. Upon NICU discharge, children were referred to the TIPS program, with scheduled follow-up appointments at approximately 6 months corrected age. All patients seen in NICU follow-up clinic with recorded scores for maternal Edinburgh postnatal depression screen (EPDS) were eligible except infants with congenital heart disease as this cohort was previously studied. Patients were stratified into groups based on presence or absence of a general surgical procedure within the first 6 months of life and positive (≥ 10) or negative (< 10) EPDS score. Statistical analyses assessed for significant differences between groups regarding gestational age, birth weight, maternal age, length of NICU stay (LOS), number of days on a ventilator, payment method, ethnicity, developmental testing, and rate of referral for early intervention services. RESULTS: Of 436 patients, 83 were surgical patients (16 with positive EPDS; 19.3% incidence), and 353 were non-surgical patients (44 with positive EPDS; 12.5% incidence). Statistical analysis showed no significant relationship between neonatal surgery and positive EPDS (χ2 = 2.6, p = 0.1). While the surgical cohort had longer LOS and days on ventilator, maternal EPDS did not predict these factors. In the surgical cohort, mothers of children not independent on oral feeding at discharge were more likely to screen positive for depression (7/14, 50% vs. 7/61, 11%; p < 0.05). CONCLUSION: Mothers of surgical patients are not significantly more likely to screen positive for post-partum depression compared to other NICU mothers. This underscores the importance of routine screening for PPD in mothers of both surgical and non-surgical NICU patients in order to identify parents and children at risk.

Development of a peptide-based fluorescent probe for biological heme monitoring.

Heme plays a vital role in cell biology and dysregulation of heme levels is implicated in a wide range of diseases. However, monitoring heme levels in biological systems is currently not straightforward. A short synthetic peptide probe containing 7-azatryptophan is shown to bind hemin in vitro with quenching of the azatryptophan fluorescence. This chemical tool can be used to detect the change in free heme induced in human skin cells upon exposure to UVA irradiation.

Dynamic release and clearance of circulating microparticles during cardiac stress.

RATIONALE: Microparticles are cell-derived membrane vesicles, relevant to a range of biological responses and known to be elevated in cardiovascular disease. OBJECTIVE: To investigate microparticle release during cardiac stress and how this response differs in those with vascular disease. METHODS AND RESULTS: We measured a comprehensive panel of circulating cell-derived microparticles by a standardized flow cytometric protocol in 119 patients referred for stress echocardiography. Procoagulant, platelet, erythrocyte, and endothelial but not leukocyte, granulocyte, or monocyte-derived microparticles were elevated immediately after a standardized dobutamine stress echocardiogram and decreased after 1 hour. Twenty-five patients developed stress-induced wall motion abnormalities suggestive of myocardial ischemia. They had similar baseline microparticle levels to those who did not develop ischemia, but, interestingly, their microparticle levels did not change during stress. Furthermore, no stress-induced increase was observed in those without inducible ischemia but with a history of vascular disease. Fourteen patients subsequently underwent coronary angiography. A microparticle rise during stress echocardiography had occurred only in those with normal coronary arteries. CONCLUSIONS: Procoagulant, platelet, erythrocyte, and endothelial microparticles are released during cardiac stress and then clear from the circulation during the next hour. This stress-induced rise seems to be a normal physiological response that is diminished in those with vascular disease.

Pre-eclampsia and offspring cardiovascular health: mechanistic insights from experimental studies.

Pre-eclampsia is increasingly recognized as more than an isolated disease of pregnancy. Women who have had a pregnancy complicated by pre-eclampsia have a 4-fold increased risk of later cardiovascular disease. Intriguingly, the offspring of affected pregnancies also have an increased risk of higher blood pressure and almost double the risk of stroke in later life. Experimental approaches to identify the key features of pre-eclampsia responsible for this programming of offspring cardiovascular health, or the key biological pathways modified in the offspring, have the potential to highlight novel targets for early primary prevention strategies. As pre-eclampsia occurs in 2-5% of all pregnancies, the findings are relevant to the current healthcare of up to 3 million people in the U.K. and 15 million people in the U.S.A. In the present paper, we review the current literature that concerns potential mechanisms for adverse cardiovascular programming in offspring exposed to pre-eclampsia, considering two major areas of investigation: first, experimental models that mimic features of the in utero environment characteristic of pre-eclampsia, and secondly, how, in humans, offspring cardiovascular phenotype is altered after exposure to pre-eclampsia. We compare and contrast the findings from these two bodies of work to develop insights into the likely key pathways of relevance. The present review and analysis highlights the pivotal role of long-term changes in vascular function and identifies areas of growing interest, specifically, response to hypoxia, immune modification, epigenetics and the anti-angiogenic in utero milieu.

Non-destructive methods to assess health of wild tropical frogs (túngara frogs: Engystomops pustulosus) in Trinidad reveal negative impacts of agricultural land.

Amphibians are threatened globally with at least 43% of species declining and the most important stressor being habitat loss or degradation. Amphibians inhabiting highly biodiverse tropical regions are disproportionately threatened; however, the effects of landscape alterations on amphibian health are virtually unknown. In this study, we utilised non-destructive techniques to compare size (weight, snout-vent length [SVL]), body condition, male secondary sexual features (forelimb width, nuptial pad length) and breeding success (egg number, fertility [percentage fertilised eggs], hatching success) in túngara frogs (Engystomops pustulosus) collected from reference (n = 5), suburban (n = 6) and agricultural (n = 4) sites in Trinidad; characterised by presence/absence of crops/houses. All measured endpoints were negatively impacted in frogs collected from agricultural sites. The largest effect was observed for hatching success (2.77-fold lower) and egg number (2.5-fold lower). Less pronounced effects were observed on male frogs (weight: 1.77-fold lower; SVL: 1.18-fold lower; forelimb width: 1.33-fold lower; nuptial pad length: 1.15-fold lower). Our findings demonstrate negative impacts of agricultural sites on túngara frog health, with the number of viable offspring reduced by almost one third. The methods outlined here are technically simple and low-cost and thereby have potential for application to other species in order to investigate the potential impacts of habitat degradation on amphibian health. Furthermore, as these methods are non-destructive, they could be used to investigate the potential contribution of frog size and/or reproductive capability as a causative factor contributing to population declines in threatened species, which is particularly pressing in tropical regions.

Deep sleep and beeps II: Sleep quality improvement project in general surgery patients.

BACKGROUND: Poor sleep leads to poor health outcomes. Phase I of our sleep quality improvement project showed severe sleep disturbance in the ward setting. We implemented a novel PostOp Pack to improve sleep quality. METHODS: Patients underwent elective, general surgery procedures. Fitbit trackers measured total sleep time. Patients completed the inpatient Richards-Campbell Sleep Questionnaire, which combines 5 domains into a cumulative score (0-100). Patients completed the outpatient Pittsburgh Sleep Quality Index preoperatively and postoperatively. Patients received the PostOp Pack, which included physical items and a sleep-protective order set to reduce nighttime awakenings. Patients from phase I served as the historical control. The primary outcome was the percentage of patients with Richards-Campbell Sleep Questionnaire total sleep score ≥50. The secondary outcomes included the mean Richards-Campbell Sleep Questionnaire domain scores and Fitbit total sleep time. RESULTS: A total of 49 patients were compared with 64 historical controls. The percentage of patients with a total sleep score ≥50 was significantly higher in patients receiving a PostOp Pack versus historical control (69% vs. 44%, difference 26%, 95% confidence interval 6.1-45%, P = .01). The mean Richards-Campbell Sleep Questionnaire Total Sleep Score was significantly higher in patients with a PostOp Pack (62 vs 49, mean difference 13, 95% confidence interval 6-21, P ≤ .01). The PostOp Pack Richards-Campbell Sleep Questionnaire domain scores were significantly higher in various areas: Sleep Latency (68 vs 49, P ≤ .01), Awakenings (56 vs 40, P = .01), Sleep Quality (61 vs 49, P = .02), and Noise Disturbance (70 vs 59, P = .04). Of all patients, 92% would use PostOp Pack again in a future hospitalization. No patients had a failure to rescue event with PostOp Pack. The mean total sleep time was significantly improved with PostOp Pack on night 1 (6.4 vs 4.7 hours, P = .03). CONCLUSION: The PostOp Pack improves inpatient sleep quality and is safe.

Uptake and trafficking of liposomes to the endoplasmic reticulum.

Liposomes are vesicular structures consisting of an aqueous core surrounded by a lipid bilayer. Apart from the cytosol and lysosomes, no other intracellular compartment has been successfully targeted using liposomal delivery. Here, we report the development of liposomes capable of specific targeting to the endoplasmic reticulum (ER) and associated membranes. Using competition and inhibitor assays along with confocal microscopy, we have determined that ER liposomes utilize scavenger and low-density lipoprotein receptors for endocytosis and enter cells through a caveolin- and microtubule-dependent mechanism. They traffic intact to the ER, where fusion with the ER membrane occurs after 22-25 min, which was confirmed by fluorescence-dequenching assays. Once inside the ER, tagged lipids intercalate with the ER membrane and are subsequently incorporated into ER-assembling entities, such as the ER-budding viruses hepatitis C virus (HCV) and bovine viral diarrhea virus (BVDV), lipid droplets, and secreted lipoproteins. ER liposomes are superior to cytosolic liposome formulations for the intracellular delivery of aqueous cargo, such as HIV-1 antivirals, and are especially suited for the prolonged delivery of lipids and lipophilic drugs into human cells.

A disposable sensor for point of care wound pH monitoring.

The development of a disposable pH sensor for the point of care monitoring of wound pH is described. The system exploits the pH dependence of an endogenous biomarker (urate) to yield an unambiguous signal. The sensor responses have been characterised and the responses validated in whole blood.

Predictors of acquired lipodystrophy in juvenile-onset dermatomyositis and a gradient of severity.

We describe the clinical features of 28 patients with juvenile dermatomyositis (JDM) and 1 patient with adult-onset dermatomyositis (DM), all of whom developed lipodystrophy (LD) that could be categorized into 1 of 3 phenotypes, generalized, partial, or focal, based on the pattern of fat loss distribution. LD onset was often delayed, beginning a median of 4.6 years after diagnosis of DM. Calcinosis, muscle atrophy, joint contractures, and facial rash were DM disease features found to be associated with LD. Panniculitis was associated with focal lipoatrophy while the anti-p155 autoantibody, a newly described myositis-associated autoantibody, was more associated with generalized LD. Specific LD features such as acanthosis nigricans, hirsutism, fat redistribution, and steatosis/nonalcoholic steatohepatitis were frequent in patients with LD, in a gradient of frequency and severity among the 3 sub-phenotypes. Metabolic studies frequently revealed insulin resistance and hypertriglyceridemia in patients with generalized and partial LD. Regional fat loss from the thighs, with relative sparing of fat loss from the medial thighs, was more frequent in generalized than in partial LD and absent from DM patients without LD. Cytokine polymorphisms, the C3 nephritic factor, insulin receptor antibodies, and lamin mutations did not appear to play a pathogenic role in the development of LD in our patients. LD is an under-recognized sequela of JDM, and certain DM patients with a severe, prolonged clinical course and a high frequency of calcinosis appear to be at greater risk for the development of this complication. High-risk JDM patients should be screened for metabolic abnormalities, which are common in generalized and partial LD and result in much of the LD-associated morbidity. Further study is warranted to investigate the pathogenesis of acquired LD in patients with DM.

Validation of the Infant-Toddler Checklist as a broadband screener for autism spectrum disorders from 9 to 24 months of age.

There is an urgent requirement for the improvement of early detection of ASDs. This article provides a brief review of research on the accuracy of screeners for children with ASD that have been administered to general pediatric samples and then present results of a population-based study with a broadband screener to detect children with communication delays including children with ASD.

Neonatal Micro-RNA Profile Determines Endothelial Function in Offspring of Hypertensive Pregnancies.

Offspring of hypertensive pregnancies are at increased risk of developing hypertension in adulthood. In the neonatal period they display endothelial cell dysfunction and altered microvascular development. MicroRNAs, as important endothelial cellular regulators, may play a role in this early endothelial dysfunction. Therefore we identified differential microRNA patterns in endothelial cells from offspring of hypertensive pregnancies and determined their role in postnatal vascular cell function. Studies were performed on human umbilical vein endothelial cell (HUVECs) samples from 57 pregnancies. Unbiased RNA-sequencing identified 30 endothelial-related microRNAs differentially expressed in HUVECs from hypertensive compared to normotensive pregnancies. Quantitative reverse transcription PCR (RT-qPCR) confirmed a significant higher expression level of the top candidate, miR-146a. Combined miR-146a targeted gene expression and pathway analysis revealed significant alterations in genes involved in inflammation, angiogenesis and immune response in the same HUVECs. Elevated miR-146a expression level at birth identified cells with reduced ability for in vitro vascular tube formation, which was rescued by miR-146a inhibition. In contrast, miR-146a overexpression significantly reduced vascular tube formation in HUVECs from normotensive pregnancies. Finally, we confirmed that mir146a levels at birth predicted in vivo microvascular development during the first three postnatal months. Offspring of hypertensive pregnancy have a distinct endothelial regulatory microRNA profile at birth, which is related to altered endothelial cell behaviour, and predicts patterns of microvascular development during the first three months of life. Modification of this microRNA profile in vitro can restore impaired vascular cell function.

Neurodevelopmental outcomes of tracheoesophageal fistulas.

PURPOSE: The purpose of this study was to perform a retrospective review of tracheoesophageal fistula (TEF) patients who followed up in a state-sponsored program to assess neurodevelopmental outcomes. METHODS: Records were reviewed retrospectively of children who underwent TEF repair between August 2001 and June 2014. Children discharged from the neonatal intensive care unit were referred to the state-sponsored Developmental Tracking Infant Progress Statewide (TIPS) program. We reviewed TIPS assessments performed before age 24months and noted referral for early school intervention services. Poor outcomes were defined as scores of "failure" on the screening assessment or referral for enrollment in early intervention services by 24months. Children with TEF were compared with case-matched nonsyndromic children of similar gestational age and birth weight. RESULTS: Seventy-eight children underwent TEF repair. Thirty-eight followed up with TIPS. Survival was 93.6%. Predictors of hospital survival were Waterston classification (p=0.001), birth weight (p=0.027), and ventilator days (p=0.013). LOS was the only significant predictor of referral for early intervention services (p=0.0092) in multivariate analysis. There was a borderline significant difference in referral rate between children with TEF and controls. 52.6% of TEF patients were referred, while 34.2% of controls were referred (p=0.071). CONCLUSION: More than half of TEF patients experience neurodevelopmental delays requiring referral for early intervention (53%).

Association of Maternal Antiangiogenic Profile at Birth With Early Postnatal Loss of Microvascular Density in Offspring of Hypertensive Pregnancies.

Offspring of hypertensive pregnancies are more likely to have microvascular rarefaction and increased blood pressure in later life. We tested the hypothesis that maternal angiogenic profile during a hypertensive pregnancy is associated with fetal vasculogenic capacity and abnormal postnatal microvascular remodeling. Infants (n=255) born after either hypertensive or normotensive pregnancies were recruited for quantification of postnatal dermal microvascular structure at birth and 3 months of age. Vasculogenic cell potential was assessed in umbilical vein endothelial cells from 55 offspring based on in vitro microvessel tube formation and proliferation assays. Maternal angiogenic profile (soluble fms-like tyrosine kinase-1, soluble endoglin, vascular endothelial growth factor, and placental growth factor) was measured from postpartum plasma samples to characterize severity of pregnancy disorder. At birth, offspring born after hypertensive pregnancy had similar microvessel density to those born after a normotensive pregnancy, but during the first 3 postnatal months, they had an almost 2-fold greater reduction in total vessel density (-17.7±16.4% versus -9.9±18.7%; P=0.002). This postnatal loss varied according to the vasculogenic capacity of the endothelial cells of the infant at birth (r=0.49; P=0.02). The degree of reduction in both in vitro and postnatal in vivo vascular development was proportional to levels of antiangiogenic factors in the maternal circulation. In conclusion, our data indicate that offspring born to hypertensive pregnancies have reduced vasculogenic capacity at birth that predicts microvessel density loss over the first 3 postnatal months. Degree of postnatal microvessel reduction is proportional to levels of antiangiogenic factors in the maternal circulation at birth.

Multiple endocrine neoplasia type 1 variant with frequent prolactinoma and rare gastrinoma.

No variant of multiple endocrine neoplasia type 1 (MEN1) has been reproducible among families. We examined two large kindreds with MEN1 variants, and we compared these to past reports. The two kindreds were followed up for 20-30 yr with MEN1 tumors in 30 members. Results in cases from two kindreds were that 93% showed parathyroid adenoma, 40% pituitary tumor (always prolactinoma), and 27% enteropancreatic endocrine tumor. The latter included 10% insulinoma, 7% nonfunctioning islet tumor, but only 10% gastrinoma. Compared with prior large series, this lower prevalence of gastrinoma (10% vs. 42%, P < 0.01) and higher prevalence of prolactinoma (40% vs. 22%, P < 0.01) define this variant. Many possible biases of retrospective analyses were excluded as possible explanations. Previously sequenced DNA showed no characteristic MEN1 mutation in these two kindreds and in a third, reported previously; the lack of any shared MEN1 mutation also excluded common ancestry for MEN1 among the three kindreds. The causes for differences between this variant and typical MEN1 are unknown. In conclusion, this variant shows more frequent prolactinoma and less frequent gastrinoma than typical MEN1; the variant is reproducible among kindreds. MEN1 carriers in such families should have periodic monitoring adjusted for the expected penetrance of tumors.

A randomized controlled trial of a theoretically-based behavioral nutrition intervention for community elders: lessons learned from the Behavioral Nutrition Intervention for Community Elders Study.

Older adults with multiple comorbidities are often undernourished or at high risk for becoming so, especially after a recent hospitalization. Randomized controlled trials of effective, innovative interventions are needed to support evidence-based approaches for solving nutritional problems in this population. Self-management approaches where participants select their own behavioral goals can enhance success of interventions. The purpose of this study was to evaluate the feasibility and efficacy of a multilevel self-management intervention to improve nutritional status in a group of high-risk older adults. The Behavioral Nutrition Intervention for Community Elders (B-NICE) trial used a prospective randomized controlled design to determine whether the intervention, compared to standard care, maintained or increased caloric intake (depending on baseline body mass index) and, consequently, stabilized or increased body weight. Participants were 34 Medicare-eligible, age 65 years old or older, homebound adults who were consuming insufficient calories and/or had a history of weight loss ≥2.5% over 6 months. The intervention took place within participants' homes. Outcome measures, including energy intake (based on collection of three 24-hour dietary recalls) and body weights were assessed at baseline and at 60 days post randomization. The primary analyses included analyses of covariance and Pearson's χ(2). We hypothesized that the intervention would result in increased caloric intake and weight gain in underweight older adults and increased or stabilized caloric intake and weight for everyone else. The intervention was feasible; however, it did not result in differences between groups for desired outcomes of either caloric intake or body weight. Future interventions might either deliberately involve caregivers or reduce burden for both patients and caregivers.
