ABSTRACT

A large portion of new patients with end stage kidney disease initiates dialysis in the acute setting and continue with outpatient dialysis at in-center facilities. To increase home dialysis adoption, programs have successfully operationalized Urgent Start peritoneal dialysis to have patients avoid in-center dialysis and move straight to home. However, Urgent Start home hemodialysis (HHD) has not been a realistic option for providers or patients due to complex machines and long training times (greater than four weeks). The landscape of dialysis treatment is evolving, and innovative approaches are being explored to improve patient outcomes and optimize health care resources. This article delves into the concept of directly transitioning incident patients from hospital admission to HHD, bypassing traditional in-center dialysis training. This forward-thinking approach aims to empower patients, enhance their treatment experience, maximize efficiency, and streamline health care operations. A large hospital organization in the Northeast was able to successfully transition three patients from hospital "crash" starts on hemodialysis directly to HHD.

ABSTRACT

Background: The use of risk stratification tools in identifying high-risk hip fracture patients plays an important role during treatment. The aim of this study was to compare our locally derived Combined Assessment of Risk Encountered in Surgery (CARES) score with the the American Society of Anesthesiologists physical status (ASA-PS) score and the Deyo-Charlson Comorbidity Index (D-CCI) in predicting 2-year mortality after hip fracture surgery. Methods and Material: A retrospective study was conducted on surgically treated hip fracture patients in a large tertiary hospital from Jan 2013 through Dec 2015. Age, gender, time to surgery, ASA-PS score, D-CCI, and CARES score were obtained. Univariate and multivariable logistic regression analyses were used to assess statistical significance of scores and risk factors, and area under the receiver operating characteristic (ROC) curve (AUC) was used to compare ASA-PS, D-CCI, and CARES as predictors of mortality at 2 years. Results: 763 surgically treated hip fracture patients were included in this study. The 2-year mortality rate was 13.1% (n = 100), and the mean ± SD CARES score of surviving and demised patients was 21.2 ± 5.98 and 25.9 ± 5.59, respectively. Using AUC, CARES was shown to be a better predictor of 2-year mortality than ASA-PS, but we found no statistical difference between CARES and D-CCI. A CARES score of 23, attributable primarily to pre-surgical morbidities and poor health of the patient, was identified as the statistical threshold for "high" risk of 2-year mortality. Conclusion: The CARES score is a viable risk predictor for 2-year mortality following hip fracture surgery and is comparable to the D-CCI in predictive capability. Our results support the use of a simpler yet clinically relevant CARES in prognosticating mortality following hip fracture surgery, particularly when information on the pre-existing comorbidities of the patient is not immediately available.

ABSTRACT

ABSTRACT: Chronic kidney disease (CKD) causes bone and mineral disorders and alterations in vitamin D metabolism that contribute to greater skeletal fragility. Hip fracture in elderly is associated with significant morbidity and mortality. The aim of this study was to investigate the outcome of elderly patients with non-dialysis dependent CKD and hip fracture undergoing surgery.Retrospective study with IRB approval of patients above 65 years of age, with hip fractures admitted between June 2014 to June 2016 in a Southeast Asian cohort. Data collected included demographic variables and the haematological and biochemical parameters HBA1c, estimated glomerular filtration rate (eGFR), serum calcium, phosphorous, and 25(OH) Vitamin D. Co-morbidities investigated were ischemic heart disease, congestive heart failure, peripheral vascular disease, malignancy, chronic obstructive pulmonary disease, cerebro vascular accident, hypertension and hyperlipidaemia. All patients were followed up from index date to either death or June 1, 2018.Of the 883 patients, 725 underwent surgery and 334 had CKD. Death rates for CKD patients with hip fractures and those with normal renal function did not differ significantly [8.08% vs 6.54%, (HR= 1.33, 95% CI: 0.95, 1.86; P = .102)], whilst median hospital length of stay was significantly higher in CKD patients [10.5 vs 9.03 days (P = .003)]. Significant risk factors associated with higher risk of mortality in the elderly with hip fracture were male gender, age ≥80 years and serum albumin < 30 g/L (all, P < .0001).In summary, in elderly, non-dialysis dependent CKD patient with hip fracture we found that male gender, age ≥80 years, low serum albumin and eGFR < 30 mL/min/1.73 m2 were associated with higher risk of death. The hospital stay in the CKD group was also longer. Additional studies are needed to validate our findings.

ABSTRACT

Microtubules (MTs) often form a polarized array with minus ends anchored at the centrosome and plus ends extended toward the cell margins. Plus ends display behavior known as dynamic instability-transitions between rapid shortening and slow growth. It is known that dynamic instability is regulated locally to ensure entry of MTs into nascent areas of the cytoplasm, but details of this regulation remain largely unknown. Here, we test an alternative hypothesis for the local regulation of MT behavior. We used microsurgery to isolate a portion of peripheral cytoplasm from MTs growing from the centrosome, creating cytoplasmic areas locally depleted of MTs. We found that in sparsely populated areas MT plus ends persistently grew or paused but never shortened. In contrast, plus ends that entered regions of cytoplasm densely populated with MTs frequently transitioned to shortening. Persistent growth of MTs in sparsely populated areas could not be explained by a local increase in concentration of free tubulin subunits or elevation of Rac1 activity proposed to enhance MT growth at the cell leading edge during locomotion. These observations suggest the existence of a MT density-dependent mechanism regulating MT dynamics that determines dynamic instability of MTs in densely populated areas of the cytoplasm and persistent growth in sparsely populated areas.

ABSTRACT

Background: Patients on maintenance hemodialysis are particularly vulnerable to infection and hospitalization from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Due to immunocompromised patients and the clustering that occurs in outpatient dialysis units, the seroprevalence of COVID-19 antibodies in this population is unknown and has significant implications for public health. Also, little is known about their risk factors for hospitalization. Methods: Three outpatient maintenance hemodialysis units affiliated with a major teaching hospital in the New York area were studied. We determined rates of SARS-CoV-2 positivity via nasopharyngeal, real-time, reverse-transcriptase PCR (RT-PCR); SARS-CoV-2 IgG seropositivity; hospitalization; and mortality. Results: Of 367 patients, 28% had either SARS-CoV-2 seropositivity or PCR positivity. Prevalence across the three respective units was 7%, 32%, and 70%. Those who were either antibody or PCR positive were significantly younger (65 versus 69 years, P=0.05), and had a higher prevalence of Black race (43% versus 30%, P=0.001) and Hispanic ethnicity (32% versus 12%, P<0.001) compared with those who tested negative. Higher positivity rates were also observed among those who took taxis and ambulettes to and from dialysis, compared with those who used personal transportation. Antibodies were detected in all of the patients with a positive PCR result who underwent serologic testing. Of those that were seropositive, 32% were asymptomatic. The hospitalization rate on the basis of either antibody or PCR positivity was 35%, with a hospital mortality rate of 33%. Aside from COPD, no other variables were more prevalent in patients who were hospitalized. Conclusions: We observed significant differences in rates of COVID-19 infection within three outpatient dialysis units, with universal seroconversion. Among patients with ESKD, rates of asymptomatic infection appear to be high, as do hospitalization and mortality rates.

ABSTRACT

Osteoporosis and cardiovascular disease are global health burdens, with postmenopausal women being at great risk. Dried plums/prunes (DPs) have been reported to provide bone health benefits in animal models, which is consistent with in vitro models. Data from human studies suggest that DP intake can enhance lipid metabolism, anti-inflammatory, and oxidant defense systems, which can impact cardiovascular health. We tested the hypothesis that short-term consumption of low and reasonable levels of DPs augments bone resorption and vascular function. Twenty-seven healthy, postmenopausal women were randomly assigned to consume six DPs (∼42 g) or two DPs (∼14 g) per day for 2 weeks, then a 2-week washout period and then crossed over. Serum C-telopeptide, beta-crosslinked (CTX) was used as a measure of bone resorption. Peripheral artery tonometry (PAT) was used to assess microvascular function. The pattern of changes in CTX in the second 2-week period (no change or decline) differed significantly from the pattern in the first 2 weeks (increases in both groups; F = 9.26, P = .006), suggesting a trend in CTX reduction (i.e., a decrease in bone resorption) in those consuming six DPs per day in the second phase. No effects on vascular function were noted. A significant interaction was observed for the augmentation index, a measure of arterial stiffness, between treatment and years after menopause (P = .045). The results suggest a potentially favorable impact of DPs on bone health when assessed with a short-term, crossover study design in postmenopausal women. Given the novel assessments used in this study, follow-up studies are warranted.

ABSTRACT

The most common renal disease associated with human immunodeficiency virus infection (HIV) is HIV-associated nephropathy (HIVAN), especially in the African American patient population. However, various patterns of glomerulonephritis (GN) are not uncommon, collectively accounting for nearly half of the renal biopsies performed in HIV patients. Most GNs that occur in HIV patients are immune complex mediated, often with concurrent infections such as hepatitis B or C. Fibrillary glomerulonephritis (FGN), a rare primary glomerular disease, has only been reported in 2 HIV patients, and both patients had concurrent hepatitis C (HCV) infection. Here we report a unique case of FGN with unusual ultrastructural morphology in an HIV-positive African American patient without concurrent HCV infection. The patient presented with nephrotic range proteinuria and renal insufficiency. A percutaneous kidney biopsy showed mesangial and segmental endocapillary proliferative GN with crescent formation. Immunofluorescence studies revealed IgG-, κ-, and C3-positive deposits in the mesangium and capillary loops. Electron microscopy demonstrated diagnostic features of FGN: randomly-arranged fibrillary deposits with a diameter of 15 - 30 nm. The deposits had an unusual distribution pattern of hump-like large deposits on the subepithelial aspect. Additionally, smaller deposits were also present in the mesangium. To our knowledge, this is the first reported case of FGN in an HIV patient without concurrent HCV infection.

ABSTRACT

T-cell acute lymphoblastic leukemia (T-ALL) and T-cell lymphoblastic lymphoma (T-LBL) are neoplasms that originate from T-cell precursors. Outcomes in adult patients with T-ALL/LBL remain unsatisfactory; early relapse following intensive induction chemotherapy is a concern, and patients with relapsed or refractory disease have a poor prognosis. Romidepsin is a potent, class 1 selective histone deacetylase inhibitor approved for the treatment of patients with peripheral T-cell lymphoma who have had ≥1 prior therapy and patients with cutaneous T-cell lymphoma who have had ≥1 prior systemic therapy. Here, we report the case of an adult patient with T-ALL refractory to induction hyperfractionated cyclophosphamide, vincristine, doxorubicin, and dexamethasone (hyper-CVAD). Treatment with romidepsin was initiated, and romidepsin in combination with hyper-CVAD resulted in complete remission, with mild tumor lysis syndrome as the only detectable additional toxicity. The patient eventually underwent allogeneic stem cell transplant while in first complete remission. Prior studies have shown that romidepsin is capable of inducing durable responses with manageable toxicities in patients with mature T-cell lymphomas. This case study describes the successful use of romidepsin in combination with hyper-CVAD in an adult patient with refractory T-ALL and highlights the activity of romidepsin in the T-cell lineage. The potential of romidepsin-containing regimens in patients with T-ALL/LBL deserves further study.

ABSTRACT

BACKGROUND: Diabetes mellitus is a worldwide pandemic that impacts more than 387 million people, with 29 million individuals affected in the United States alone. Diabetic patients have a 25% lifetime risk of developing a diabetic foot ulcer (DFU). Having a DFU is associated with a risk of recurrence approaching 70%. In addition, 1 in 6 patients with DFU will have a lower-limb amputation, with an associated increase in mortality ranging from 47% to 70%. Therefore, limb salvage is critical in patients with DFU. CASE STUDY: This article describes the case of a 70-year-old man with diabetes mellitus, end-stage renal disease, and peripheral arterial occlusive disease who presented with a 1.5% total-body-surface-area, third-degree burn to the left hallux with dry gangrene extending to the midfoot. Ankle brachial indexes were 0.66 on the left and 0.64 on the right. Toe pressures on the left were absent because of extensive dry gangrene. His right foot had a prior transmetatarsal amputation. Using a retrograde pedal approach, a chronic total occlusion of the left posterior tibial artery was recanalized with balloon angioplasty. He then underwent a transmetatarsal amputation with closure, except that the plantar medial side could not be closed without tension. Therefore, an autologous full-thickness skin graft, from the amputation specimen, was used to bridge the defect. DISCUSSION: At 32-week follow-up, the wound was healed, the graft had fully incorporated, and the patient was ambulating well using custom orthotic footwear. The creative use of amputated tissue to assist with wound coverage has not been well described in the literature.
