Loneliness, immunological recovery patterns, and health-related quality of life (HRQOL) outcomes in patients receiving hematopoietic stem cell transplantation.

PURPOSE: Loneliness may compromise health-related quality of life (HRQOL) outcomes and the immunological impacts of loneliness via neuroendocrinological mechanisms likely have consequences for patients who have undergone a hematopoietic stem cell transplantation (HSCT). RESEARCH APPROACH AND MEASURES: Loneliness (pre-transplant), immunological recovery (Day 30, Day 100, 1-year post-transplant), and HRQOL (Day 100, 1 year) were measured in a sample of 205 patients completing a HSCT (127 autologous, 78 allogenic). RESULTS: Greater levels of pre-transplant loneliness predicted poorer HRQOL at Day 100 and 1-year follow-up. Loneliness also was associated with higher absolute neutrophil to absolute lymphocyte (ANC/ALC) ratios in the entire sample at Day 30, which in turn was associated with Day 100 HRQOL. CONCLUSIONS: Findings demonstrate that pretransplant loneliness predicts HRQOL outcomes and associates with inflammatory immunological recovery patterns in HSCT patients. The balance of innate neutrophils to adaptive lymphocytes at Day 30 present a distinct profile in lonely individuals, with this immunity recovery profile predicting reduced HRQOL 100 days after the transplant. Addressing perceptions of loneliness before HSCT may be an important factor in improving immunological recovery and HRQOL outcomes.

A Parathyroid Hormone-Guided Calcium and Calcitriol Supplementation Protocol Reduces Hypocalcemia-Related Readmissions Following Total Thyroidectomy.

OBJECTIVE: To determine the effect of a 4-hour postoperative serum parathyroid hormone (PTH)-guided calcium (Ca) and calcitriol supplementation protocol on the incidence of hypocalcemia and hospital readmissions in patients undergoing total thyroidectomy. METHODS: This was a single-institution, retrospective chart review of patients who underwent total thyroidectomy; 148 and 389 of the patients underwent surgery prior to and after the protocol implementation, respectively. The risk of hypocalcemia was stratified as low (PTH level of >30 pg/mL), medium (15-30 pg/mL), and high (<15 pg/mL), using serum PTH values obtained 4 hours postoperatively. Hypocalcemia was defined as a total serum Ca level of <8 mg/dL. Baseline demographic and operative characteristics and postoperative outcome were recorded for both groups. The Fisher exact test and Wilcoxon rank sum test were used to compare the characteristics of the 2 groups. A multivariate logistic regression model was applied to account for potentially confounding variables. RESULTS: Postoperative hypocalcemia occurred significantly less frequently in the protocol group compared with that in the preprotocol group (10.3% vs 20.9%, P = .002). The reduction in hypocalcemia in the protocol group was observed in both patients with (16.3% vs 25.6%) and without (8.4% vs 19.3%) cervical lymph node dissection. The protocol group had a significantly lower incidence of hospital readmission events than the preprotocol group (1.0% vs 4.7%, P = .013). CONCLUSION: Compared with a historical cohort, a PTH-guided protocol for Ca and calcitriol supplementation significantly reduces the postoperative hypocalcemia and hospital readmission rates in patients undergoing total thyroidectomy.

Structural connectivity-based segmentation of the thalamus and prediction of tremor improvement following thalamic deep brain stimulation of the ventral intermediate nucleus.

OBJECTIVES: Traditional targeting methods for thalamic deep brain stimulation (DBS) performed to address tremor have predominantly relied on indirect atlas-based methods that focus on the ventral intermediate nucleus despite known variability in thalamic functional anatomy. Improvements in preoperative targeting may help maximize outcomes and reduce thalamic DBS-related complications. In this study, we evaluated the ability of thalamic parcellation with structural connectivity-based segmentation (SCBS) to predict tremor improvement following thalamic DBS. METHODS: In this retrospective analysis of 40 patients with essential tremor, hard segmentation of the thalamus was performed by using probabilistic tractography to assess structural connectivity to 7 cortical targets. The volume of tissue activated (VTA) was modeled in each patient on the basis of the DBS settings. The volume of overlap between the VTA and the 7 thalamic segments was determined and correlated with changes in preoperative and postoperative Fahn-Tolosa-Marin Tremor Rating Scale (TRS) scores by using multivariable linear regression models. RESULTS: A significant association was observed between greater VTA in the supplementary motor area (SMA) and premotor cortex (PMC) thalamic segment and greater improvement in TRS score when considering both the raw change (P = .001) and percentage change (P = .011). In contrast, no association was observed between change in TRS score and VTA in the primary motor cortex thalamic segment (P ≥ .19). CONCLUSIONS: Our data suggest that greater VTA in the thalamic SMA/PMC segment during thalamic DBS was associated with significant improvement in TRS score in patients with tremor. These findings support the potential role of thalamic SCBS as an independent predictor of tremor improvement in patients who receive thalamic DBS.

The Benefit of Supplemental Nutrition Education for Severely Malnourished Patients Awaiting Liver Transplant.

INTRODUCTION: Nutritional interventions improve patient outcomes and reduce mortality in patients with cirrhosis by reducing infection risk, ascites, length of stay in hospital and intensive care unit, and mortality. Follow-up phone calls have been found to be useful in improving patient adherence to therapy. PROBLEM: The purpose of this quality improvement project was to determine whether supplemental nutrition education would improve nutrition and outcomes among patients with cirrhosis who are undergoing a liver transplant evaluation. In addition, we sought to measure patient adherence with nutritional recommendations and whether patients perceived this additional education improved their nutrition status. METHODS: The Plan-Do-Study-Ask methodology was used. PROCESSES: Addressed 8 patients were enrolled to participate in the supplemental nutrition education, after which they received 3 follow-up phone calls. A retrospective review of data from 10 patients meeting project inclusion criteria were identified by the nutrition specialist and were used as a comparison group. Data were analyzed using descriptive statistics; comparing data from before and after implementation of the supplemental nutrition education was done. OUTCOMES: At the end of the 8-week project period, 4 (66.7%) patients reported weight loss since the time of enrollment (nutrition education class), and the median patient-generated subjective global assessment score increased by 4 points, rather than decreasing as expected. However, all patients reported they believed the phone calls improved their nutrition status. IMPLICATIONS: With a multidisciplinary approach, this additional patient education may improve patient care and outcomes.

Timing interval from peri-prostatic block to biopsy impacts procedural pain.

INTRODUCTION: To compare visual analog scale (VAS) pain scores between patients with a 2-minute versus 10-minute delay of peri-prostatic lidocaine injection prior to transrectal ultrasound-guided prostate biopsies (TRUS-bx). MATERIALS AND METHODS: Eighty patients who underwent standard 12-core TRUS-bx by a single surgeon were prospectively randomized into four different treatment arms: bibasilar injection with a 2-minute delay, bibasilar injection plus a single apical injection with a 2-minute delay, bibasilar injection with a 10-minute delay, and bibasilar injection plus a single apical injection with a 10-minute delay. Patients were asked to report their level of pain on the VAS (0-10, with 10 indicating unbearable pain) at the following intervals: probe insertion (baseline), after each core, and post-procedure. The primary outcome measure was mean VAS score across all 12 cores minus baseline VAS score, which we refer to baseline-adjusted mean VAS score. RESULTS: Baseline-adjusted mean VAS score was significantly higher for the 2-minute delay group compared to the 10-minute delay group (mean: -0.7 versus -1.6, p = 0.025). Subset analysis of biopsies 1-3, 4-6, 7-9 and 10-12 also demonstrated higher baseline-adjusted mean VAS scores in the 2-minute delay group (all p ≤ 0.043). CONCLUSIONS: Lower TRUS-bx VAS scores can be achieved by extending the time from lidocaine injection to onset of prostate biopsy from 2 to 10 minutes.

Impact of Minimally Invasive Benign Prostatic Hyperplasia Therapies on 30- and 90-Day Postoperative Office Encounters.

OBJECTIVE: To compare the frequency of postoperative encounters in the 30-day and 90-day postoperative periods for various bladder outlet obstruction surgical therapies. MATERIALS AND METHODS: All patients who underwent transurethral resection of the prostate (TURP), GreenLight laser photovaporization of the prostate (GL-PVP) (American Medical Systems Inc.), and holmium laser enucleation of the prostate (HoLEP) from January 1, 2012 to December 31, 2014 were followed for 6 months postoperatively. All postoperative encounters such as patient calls or questions, catheter exchanges or removals, and hospital-based readmissions or emergency department visits were recorded in the electronic medical record. RESULTS: Two hundred and ninety-one consecutive patients underwent outlet procedures during the study period: TURP (N = 199; mean age, 71 years; mean body mass index [BMI], 28.5), HoLEP (N = 60; mean age, 68 years; mean BMI, 28.1), or GL-PVP (N = 32; mean age, 72 years; mean BMI, 29.3). No statistically significant difference was observed for age, BMI, preoperative American Urological Association symptom score, or preoperative maximum flow velocity between the 3 groups. Thirty-day postoperative encounters differed significantly between the 3 surgery types (P < .001). Specifically, there were fewer encounters within 30 days of surgery for TURP compared to both HoLEP (≥1 encounter: TURP = 48.7%, HoLEP = 66.7%; P = .006) and GL-PVP (≥1 encounter: TURP = 48.7%, GL-PVP = 93.7%; P < .001). The number of encounters within 90 days postoperatively was also significantly lower for TURP patients (P < .001). CONCLUSION: TURP results in fewer postoperative encounters in both the 30-day and 90-day postoperative periods compared to HoLEP and GL-PVP. Laser prostate therapies may place increased burden on clinic staff during the 30-day and 90-day postoperative periods.

EFFECTIVENESS AND OUTCOMES OF CURRENT PRACTICE IN TREATING VITAMIN D DEFICIENCY IN PATIENTS LISTED FOR LIVER TRANSPLANTATION.

OBJECTIVE: Vitamin D deficiency is prevalent in cirrhotic patients awaiting liver transplantation (LT). Optimal vitamin D management for these patients remains undefined. We sought to determine the effectiveness of our practice in addressing vitamin D deficiency in LT patients. METHODS: This retrospective study included 127 patients who received a first LT between July 2010 and July 2011. Outcomes measured included readmission rates, fractures, and functional status post-LT. 25-Hydroxyvitamin D (25-OH D) deficiency was stratified as: mild (20-30 ng/mL), moderate (15-19.9 ng/mL), and severe (<15 ng/mL). We estimated the amount of vitamin D supplementation required for each patient. RESULTS: At LT evaluation, 107 patients (84%) had vitamin D deficiency, and 74% remained vitamin D deficient at LT. Only 62% received vitamin D supplementation pre-LT. Moderate and severe deficiencies were less common at LT and rare 4 months post-LT. There was an association between improvement in vitamin D deficiency category at LT and increased vitamin D (>400,000 IU total) supplementation (P = .004). We found no association between vitamin D deficiency at LT and functional status, fractures, or readmissions post-LT. Patients receiving induction immunosuppressant therapy with basiliximab had a significantly greater degree of worsening in bone mineral density (BMD) post-LT. CONCLUSION: Moderate-to-severe vitamin D deficiency was very prevalent in a cohort of patients undergoing evaluation for LT. Deficiency was improved with increased vitamin D replacement therapy. Vitamin D deficiency at LT was not associated with worse bone or functional outcomes post-LT. The influence of basiliximab on bone health post-LT requires further evaluation.

Optimizing screening for osteoporosis in patients with fragility hip fracture.

BACKGROUND: Osteoporosis, the underlying cause of most hip fractures, is underdiagnosed and undertreated. The 2008 Joint Commission report Improving and Measuring Osteoporosis Management showed only an average of 20% of patients with low-impact fracture are ever tested or treated for osteoporosis. We developed an integrated model utilizing hospitalists and orthopaedic surgeons to improve care of osteoporosis in patients with hip fracture. QUESTIONS/PURPOSES: Does our integrated model combining hospitalists and orthopaedic surgeons improve the frequency of evaluation for osteoporosis, screening for secondary causes, and patients' education on osteoporosis? PATIENTS AND METHODS: Our Hospitalist-Orthopaedic Surgeon Integrated Model of Care was implemented in September 2009. We compared the rate of evaluation and treatment of osteoporosis in 140 patients admitted with fragility hip fracture at our institution before (70 patients) and after (70 patients) implementation of the care plan. RESULTS: Evaluation of patients for osteoporosis was higher in the postimplementation group compared to the preimplementation group (89% versus 24%). Screening of patients for secondary causes of osteoporosis was also improved in the postimplementation group (89% versus 0%), as was the proportion of patients who received education for osteoporosis management (89% versus 0%). CONCLUSION: Our model of integrated care by hospitalists and orthopaedic surgeons resulted in improvement in the evaluation for osteoporosis, screening for secondary causes of osteoporosis, and education on osteoporosis management in patients with hip fracture at our institution. This may have important implications for treatment of these patients. LEVEL OF EVIDENCE: Level III, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.

Defining normal duration for afterdischarges with repetitive nerve stimulation: a pilot study.

The presence of afterdischarges on repetitive nerve stimulation may be useful to diagnose cramp fasciculation syndrome, however, the presence and normal duration of afterdischarges has not been well-defined in the normal population and individuals with other neuromuscular diseases. The aim of this pilot study was to describe the distribution of afterdischarge durations in normal controls and patients with peripheral neuropathy. The estimated seventy-fifth percentiles of the afterdischarge durations following tibial nerve repetitive nerve stimulation at 2, 5, 10, and 20 Hz were 315, 688, 745, and 928 milliseconds for 18 normal patients, and 143, 31, 323, and 542 milliseconds for 18 peripheral neuropathy patients respectively. Afterdischarge durations were similar in peripheral neuropathy patients and controls. These findings suggest that afterdischarge durations of more than 500 milliseconds are common in normal controls without subjective cramps and patients with peripheral neuropathy, with some durations beyond 1,000 milliseconds. Therefore, the presence of afterdischarges on repetitive nerve stimulation should be interpreted with caution when evaluating patients for hyperexcitable nerve syndromes.
