Body mass index and Mini Nutritional Assessment-Short Form as predictors of in-geriatric hospital mortality in older adults with COVID-19.

BACKGROUND & AIMS: Overweight and obesity have been consistently reported to carry an increased risk for poorer outcomes in coronavirus disease 2019 (COVID-19) in adults. Existing reports mainly focus on in-hospital and intensive care unit mortality in patient cohorts usually not representative of the population with the highest mortality, i.e. the very old and frail patients. Accordingly, little is known about the risk patterns related to body mass and nutrition in very old patients. Our aim was to assess the relationship between body mass index (BMI), nutritional status and in-geriatric hospital mortality among geriatric patients treated for COVID-19. As a reference, the analyses were performed also in patients treated for other diagnoses than COVID-19. METHODS: We analyzed up to 10,031 geriatric patients with a median age of 83 years of which 1409 (14%) were hospitalized for COVID-19 and 8622 (86%) for other diagnoses in seven geriatric hospitals in the Stockholm region, Sweden during March 2020-January 2021. Data were available in electronic hospital records. The associations between 1) BMI and 2) nutritional status, assessed using the Mini-Nutritional Assessment - Short Form (MNA-SF) scale, and short-term in-geriatric hospital mortality were analyzed using logistic regression. RESULTS: After adjusting for age, sex, comorbidity, polypharmacy, frailty and the wave of the pandemic (first vs. second), underweight defined as BMI<18.5 increased the risk of in-hospital mortality in COVID-19 patients (odds ratio [OR] = 2.30; confidence interval [CI] = 1.17-4.31). Overweight and obesity were not associated with in-hospital mortality. Malnutrition; i.e. MNA-SF 0-7 points, increased the risk of in-hospital mortality in patients treated for COVID-19 (OR = 2.03; CI = 1.16-3.68) and other causes (OR = 6.01; CI = 2.73-15.91). CONCLUSIONS: Our results indicate that obesity is not a risk factor for very old patients with COVID-19, but emphasize the role of underweight and malnutrition for in-hospital mortality in geriatric patients with COVID-19.

Health status and health care utilization after discharge from geriatric in-hospital stay - description of a register-based study.

BACKGROUND: This study is the first part of a register-based research program with the overall aim to increase the knowledge of the health status among geriatric patients and to identify risk factors for readmission in this population. The aim of this study was two-fold: 1) to evaluate the validity of the study cohorts in terms of health care utilization in relation to regional cohorts; 2) to describe the study cohorts in terms of health status and health care utilization after discharge. METHODS: The project consist of two cohorts with data from patient records of geriatric in-hospital stays, health care utilization data from Stockholm Regional Healthcare Data Warehouse 6 months after discharge, socioeconomic data from Statistics Sweden. The 2012 cohort include 6710 patients and the 2016 cohort, 8091 patients; 64% are women, mean age is 84 (SD 8). RESULTS: Mean days to first visit in primary care was 12 (23) and 10 (19) in the 2012 and 2016 cohort, respectively. Readmissions to hospital was 38% in 2012 and 39% in 2016. The validity of the study cohorts was evaluated by comparing them with regional cohorts. The study cohorts were comparable in most cases but there were some significant differences between the study cohorts and the regional cohorts, especially regarding amount and type of primary care. CONCLUSION: The study cohorts seem valid in terms of health care utilization compared to the regional cohorts regarding hospital care, but less so regarding primary care. This will be considered in the analyses and when interpreting data in future studies based on these study cohorts. Future studies will explore factors associated with health status and re-admissions in a population with multi-morbidity and disability.

Experiences of supporting older persons in completion of an exercise and nutrition intervention: an interview study with nursing home staff.

BACKGROUND: The interactions between nursing home (NH) staff and their residents are crucial not only for the atmosphere at the NH but also for achieving care goals. In order to test the potential effects of daily physical activities (sit-to-stand (STS) exercises) combined with oral nutritional supplementation (ONS), a randomized intervention trial (the Older Person's Exercise and Nutrition (OPEN) Study) was performed in NH residents. One aspect of the study was to interview and report the NH staff's experiences of supporting the residents in fulfilling the intervention. METHODS: In this qualitative study, individual and focus group interviews were performed in eight NH facilities with NH staff who had assisted residents in performing the 12-week ONS/STS intervention. An interview guide developed for this study was used to assess staff experiences of the intervention and its feasibility. The transcribed interviews were analyzed inductively following a constant comparative method and with input from experts in the area, described in Grounded Theory as a reliable technique for researchers to form theory and hypothesis in unexplored areas. RESULTS: Three main themes relating to the health-promoting intervention emerged. These included: 1) insights into attitudes towards health in general and NH care specifically; 2) intervention-related challenges, frustrations and needs, and 3) aspects of collaboration and opportunities. The overarching hypothesis derived from the analysis reads: A health-promoting intervention such as the OPEN-concept has great potential for integration into NH life if a combined empathic and encouraging attitude, and a structure to keep it sustainable, are in place. CONCLUSIONS: NH staff experienced the health-promoting intervention as a potentially positive concept, although it was suggested that it works best if introduced as a general routine in the unit and is integrated into the daily planning of care. TRIAL REGISTRATION: ClinicalTrials.govIdentifier: NCT02702037 . Date of trial registration February 26, 2016. The trial was registered prospectively.

Do Malnutrition, Sarcopenia and Frailty Overlap in Nursing-Home Residents?

OBJECTIVES: To study the prevalence and overlap between malnutrition, sarcopenia and frailty in a selected group of nursing home (NH) residents. DESIGN: Cross-sectional descriptive study. SETTING: Nursing homes (NH). PARTICIPANTS: 92 residents taking part in an exercise and oral nutritional supplementation study; >75 years old, able to rise from a seated position, body mass index ≤30 kg/m2 and not receiving protein-rich oral nutritional supplements. MEASUREMENTS: The MNA-SF and Global Leadership Initiative on Malnutrition (GLIM) criteria were used for screening and diagnosis of malnutrition (moderate or severe), respectively. Sarcopenia risk was assessed by the SARC-F Questionnaire (0-10p; ≥4=increased risk), and for diagnosis the European Working Group of Sarcopenia in Older People (EWGSOP2) criteria was used. To screen for frailty the FRAIL Questionnaire (0-5p; 1-2p indicating pre-frailty, and >3p indicating frailty), was employed. RESULTS: Average age was 86 years; 62% were women. MNA-SF showed that 30 (33%) people were at risk or malnourished. The GLIM criteria verified malnutrition in 16 (17%) subjects. One third (n=33) was at risk for sarcopenia by SARC-F. Twenty-seven (29%) subjects displayed confirmed sarcopenic according to EWGSOP2. Around 50% (n=47) was assessed as pre-frail or frail. Six people (7%) suffered from all three conditions. Another five (5%) of the residents were simultaneously malnourished and sarcopenic, but not frail, while frailty coexisted with sarcopenia in 10% (n=9) of non-malnourished residents. Twenty-nine (32%) residents were neither malnourished, sarcopenic nor frail. CONCLUSIONS: In a group of selected NH residents a majority was either (pre)frail (51%), sarcopenic (29%) or malnourished (17%). There were considerable overlaps between the three conditions.

Barriers and enablers in the implementation of a standardised process for nutrition care: findings from a multinational survey of dietetic professionals in 10 countries.

BACKGROUND: To explore the barriers and enablers experienced by nutrition and dietetic professionals in the implementation of the standardised Nutrition Care Process (NCP) across 10 different countries. NCP related beliefs, motivations and values were investigated and compared. METHODS: A validated online survey was disseminated to nutrition and dietetics professionals in 10 countries in the local language during 2017. Cross-sectional associations and differences between countries were explored for level of implementation, barriers/enablers and attitudes/motivation among the respondents. RESULTS: Higher NCP implementation was associated with greater occurrence of enabling aspects, as well as fewer occurrences of barriers. The most common enabler was 'recommendation by the national dietetic association' (69%) and the most common barrier was 'lack of time' (39%). A longer experience of NCP use was associated with a more positive attitude towards all NCP aspects. Differences between countries were identified, regarding both the occurrence of barriers/enablers and attitudes/motivations. CONCLUSIONS: Implementation efforts need to be tailored to country-specific contexts when implementing a new standard of care framework among nutrition and dietetic professionals. Additional research is needed to further assess the management and workplace strategies to support the development of nutrition and dietetics professionals in multidisciplinary healthcare organisations.

New parents' experience of information and sense of security related to postnatal care: A systematic review.

BACKGROUND: Becoming a parent is often a tumultuous experience and a great challenge. The transition when a child is born is described affecting the parents and their relationship psychically, physically, mentally and emotionally. Information within care should be relevant and supportive. Furthermore information within the context of care should be relevant, supportive and helpful to parents in handling their new situation and increasing their self-reliance. AIM: To provide a contextualised understanding of how parents experience postnatal care in relation to information and sense of security". METHOD: A systematic search was undertaken at PubMed and CINAHL database for literature published between January 2002 and August 2017. Inclusion criteria focused on postnatal care. Eight of the studies used qualitative methods and two of the studies used quantitative methods, as a result the findings could not be combined using meta-analysis or meta-synthesis, instead narrative synthesis of the findings were used. RESULTS: Ten studies were included. The analysis revealed three categories related to parent's experience of information and sense of security during the postnatal period. These categories were; Expectations on the care; Own resources; and Confirmation. Support from staff and family is described as significant for the parents' sense of security. During the first postnatal week, the emotions were characterized by anxiety and/or fear. Parents prefer a "non-judgmental" attitude from the staff and to be met as an individual. CONCLUSION: Family -centred care such as continuity, participation, individually adaptation, consistent, information and preparation for parenting appear to be important components for parents' sense of security in postnatal care.

Correction: Plasma 1-deoxysphingolipids are early predictors of incident type 2 diabetes mellitus.

[This corrects the article DOI: 10.1371/journal.pone.0175776.].

Plasma 1-deoxysphingolipids are early predictors of incident type 2 diabetes mellitus.

1-Deoxysphingolipids (1-deoxySLs) are atypical sphingolipids, which are formed in a side reaction during sphingolipid de-novo synthesis. Recently, we demonstrated that 1-deoxySLs are biomarkers for the prediction of T2DM in obese, non-diabetic patients. Here we investigated the relevance of 1-deoxySLs as long-term predictive biomarkers for the incidence of T2DM in an asymptomatic population. Here, we analyzed the plasma sphingoid base profile in a nested group of non-diabetic individuals (N = 605) selected from a population-based study including 5 year follow-up data (CoLaus study). 1-DeoxySLs at baseline were significantly elevated in individuals who developed T2DM during the follow-up (p<0.001), together with increased glucose (p<5.11E-14), triglycerides (p<0.001) and HOMA-IR indices (p<0.001). 1-Deoxy-sphinganine (1-deoxySA) and 1-deoxy-sphingosine (1-deoxySO) were predictive for T2DM, even after adjusting for fasting glucose levels in the binary regression analyses. The predictive value of the combined markers 1-deoxySA+glucose were superior to glucose alone in normal-weight subjects (p<0.001) but decreased substantially with increasing BMI. Instead, plasma adiponectin and waist-to-hip ratio appeared to be better risk predictors for obese individuals (BMI>30kg/m2). In conclusion, elevated plasma 1-deoxySL levels are strong and independent risk predictors of future T2DM, especially for non-obese individuals in the general population.

A methylome-wide mQTL analysis reveals associations of methylation sites with GAD1 and HDAC3 SNPs and a general psychiatric risk score.

Genome-wide association studies have identified a number of single-nucleotide polymorphisms (SNPs) that are associated with psychiatric diseases. Increasing body of evidence suggests a complex connection of SNPs and the transcriptional and epigenetic regulation of gene expression, which is poorly understood. In the current study, we investigated the interplay between genetic risk variants, shifts in methylation and mRNA levels in whole blood from 223 adolescents distinguished by a risk for developing psychiatric disorders. We analyzed 37 SNPs previously associated with psychiatric diseases in relation to genome-wide DNA methylation levels using linear models, with Bonferroni correction and adjusting for cell-type composition. Associations between DNA methylation, mRNA levels and psychiatric disease risk evaluated by the Development and Well-Being Assessment (DAWBA) score were identified by robust linear models, Pearson's correlations and binary regression models. We detected five SNPs (in HCRTR1, GAD1, HADC3 and FKBP5) that were associated with eight CpG sites, validating five of these SNP-CpG pairs. Three of these CpG sites, that is, cg01089319 (GAD1), cg01089249 (GAD1) and cg24137543 (DIAPH1), manifest in significant gene expression changes and overlap with active regulatory regions in chromatin states of brain tissues. Importantly, methylation levels at cg01089319 were associated with the DAWBA score in the discovery group. These results show how distinct SNPs linked with psychiatric diseases are associated with epigenetic shifts with relevance for gene expression. Our findings give a novel insight on how genetic variants may modulate risks for the development of psychiatric diseases.

Risk factors for acute and overuse sport injuries in Swedish children 11 to 15 years old: What about resistance training with weights?

To determine the 1-year self-reported incidence of overuse and traumatic sport injuries and risk factors for injuries in children participating in a summer sports camp representing seven different sports. 4363 children, 11 to 15 years old participating in a summer camp in seven different sports answered a questionnaire. Injury in this cross-sectional study was defined as a sport-related trauma or overload leading to pain and dysfunction preventing the person from participation in training or competition for at least 1 week. A number of risk factors for injury were investigated such as sex, age, number of hours spent on training in general, and on resistance training with weights. Nearly half [49%, 95% confidence interval (CI) 48-51%] of the participants had been injured as a result of participation in a sport during the preceding year, significantly more boys than girls (53%, 95% CI 50-55% vs 46%, 95% CI 43-48%; P < 0.001). Three factors contributed to increased incidence of sport injuries: age, sex, and resistance training with weights. Time spent on resistance training with weights was significantly associated with sport injuries in a logistic regression analysis. In children age 11 to 15 years, the risk of having a sport-related injury increased with age and occurred more often in boys than in girls. Weight training was the only modifiable risk factor that contributed to a significant increase in the incidence of sport injuries.

Treatment results in patients with intracranial ependymomas.

OBJECTIVE: To evaluate the treatment outcomes of patients with intracranial ependymomas. METHODS: Between 1988-2007, 27 consecutive patients, with 9 patients (33%) aged under 16 years, were treated at our institution for an intracranial ependymoma. Pertinent clinical data were retrieved from the patients' charts. The histopathological findings in 25 cases were reviewed using the 2007 World Health Organization (WHO) classification system. Median follow-up was 84 months. RESULTS: Infratentorial tumors were diagnosed in 22, and supratentorial tumors in 5 patients. Histopathological findings were ependymoma WHO grade II (E II) in 14 patients, and anaplastic ependymoma WHO grade III (AE III) in 13 patients. A complete tumor resection was achieved with the first operation in 20 cases (74%). Primary adjuvant therapy consisted of chemotherapy alone in a 17-month-old child with an incompletely resected posterior fossa AE III, radiation therapy alone in 4 cases, and combined radiation therapy and chemotherapy in 7 cases. Tumor recurrence was seen in 10 cases (37%), including 5 patients with an E II and 5 patients with an AE III. The 5-year progression-free survival (PFS) was 74% and 67% for E II and AE III, respectively. The 5-year PFS was 80% following a complete resection, and 56% in patients with a residual tumor. CONCLUSIONS: Surgery alone, as the primary treatment, achieves a good outcome in most patients with E II. Good results can be achieved with surgery and adjuvant local radiotherapy in patients with AE III.

Diabetes mellitus: a risk factor for delayed graft function after deceased donor kidney transplantation.

Early graft function is a major determinant of long-term outcomes after renal transplantation. Recently, recipient diabetes was identified as a risk factor for poor initial graft function in living donor renal transplantation. To further explore this association, we performed a paired analysis of deceased donor renal transplants from January 1994 to December 2005. A total of 25,523 transplant pairs were analyzed via conditional logistic regression. Diabetic recipients were older (53.16 vs. 46.75 years, p < 0.01), had a lower average panel reactive antibody (12% vs. 15%, p < 0.01) and fewer prior transplants (0.07 vs. 0.12, p < 0.01). Recipient diabetes, age, male gender, African American race, elevated peak panel reactive antibody and increased cold ischemia time were independent risk factors for delayed graft function. Specifically, diabetic recipients had increased risk of DGF on univariate analysis (odds ratio [OR] 1.32, 95% confidence interval [CI] 1.23-1.42, p < 0.01). Multivariable analysis confirmed this association but the risk differed by recipient gender; with diabetes having a greater effect in women (OR 1.66, 95% CI 1.45-1.91, p < 0.01) compared to men (OR 1.28, 95% CI 1.15-1.43, p < 0.01). It is unknown whether the deleterious impact of recipient diabetes on graft function after renal transplantation results from perioperative hyperglycemia or the chronic sequelae of diabetes.

Intramedullary hemangioblastomas: timing of surgery, microsurgical technique and follow-up in 23 patients.

Hemangioblastomas are highly vascularised tumors of the central nervous system and account for 1.5-2.5% of all spinal cord tumors. Because of the rarity of these tumors, surgical experience is often limited and, therefore, treatment and indications for timing of surgery are discussed controversial. The authors reviewed their data of 23 consecutive patients with respect to timing of surgery, microsurgical technique, and follow-up. Clinical records of 23 consecutive patients with intramedullary hemangioblastomas who underwent first surgery in our department between 1990 and 2005 were reviewed. In three cases the tumors were localised at the craniocervical junction; four patients had a single tumor in the cervical spine, six patients multiple tumors in the cervical and thoracic spine, eight patients in the thoracic spine only, one patient in the conus region, and one patient had multiple tumors located in the thoracic and lumbar spine. In eight patients, a von-Hippel-Lindau disease (VHL) was associated. The neurological follow-up was evaluated according to the classification of McCormick. Operation was recommended to every symptomatic patient as early as possible. In asymptomatic patients with a sporadic tumor surgery was discussed for diagnostic purposes at any time. In VHL patients, surgery was recommended if tumor growth was observed on MRI in the next practicable time. All tumors were diagnosed by magnetic resonance imaging and in all cases but one a DSA was performed. All patients were treated microsurgically through a posterior approach. The tumors in the spinal cord were removed microsurgically through a partial hemilaminectomy (n = 1), a hemilaminectomy (n = 15), or laminectomy (n = 4) and at the craniocervical junction (n = 3) through a suboccipital craniotomy. During follow-up after 6 months, 18 patients remained neurologically stable (17 in McCormick grade I and 1 in McCormick grade II) and 5 patients recovered to a better status (3 from grade III to II, 2 from grade II to I). There was one complication with a CSF fistula and one recurrence/incomplete removal. Following the above-mentioned principles of microsurgical removal of intramedullary hemangioblastomas, operation is possible with a low procedure-related morbidity and can be recommended especially in VHL patients with progressive symptoms or tumor growth during follow-up. Patients without VHL most frequently require hemangioblastoma resection for diagnostic purposes and/or because symptoms prompted an imaging work-up that lead to the discovery of the tumor.

A less invasive surgical concept for the resection of spinal meningiomas.

BACKGROUND: The surgical strategy for spinal meningiomas usually consists of laminectomy, initial tumour debulking, identification of the interface between tumour and spinal cord, resection of the dura including the matrix of the tumour, and duroplasty. The objective of this study was to investigate whether a less invasive surgical strategy consisting of hemilaminectomy or laminectomy, tumour removal and coagulation of the tumour matrix allows comparable surgical and clinical results to be obtained, especially without an increase of the recurrence rate as reported in the literature. PATIENTS AND METHODS: Between 1990 and 2005, 61 patients (11 men, 50 women) underwent surgery for spinal meningioma. All patients were treated microsurgically by a posterior approach. In 56 of the 61 patients, the above outlined - less invasive - surgical technique with tumour removal and coagulation of the tumour matrix was performed. In 5 patients, dura resection and duroplasty was additionally performed. Electrophysiological monitoring was routinely used since 1996. Recurrence was defined as new onset or worsening of symptoms and radiological confirmation of tumour growth. The pre-and post-operative clinical status was measured by the Frankel grading system. RESULTS: Pre-operatively, 40 patients were in Frankel grade D, 13 patients in grade C, 6 patients in grade E and 1 patient each in grade A and B. Following surgery no patient presented a permanent worsening of clinical symptoms. All patients who initially presented with a Frankel grades A-C (n = 15) recovered to a better grade at the time of follow-up. Patients who presented with Frankel grade D remained in stable condition (n = 27) or recovered to a better neurological status (n = 13). Two patients experienced a temporary worsening of their symptoms, but subsequently improved to a better state than pre-operatively. Two (3.3%) complications (pseudomeningocele, wound infection) requiring surgery, were encountered. The pseudomeningocele developed in a patient who underwent durotomy. During the follow-up period of 2 months to 10 years (mean 31.3 months), 3 patients (5%) required surgery for symptomatic recurrence: 1 patient had 2 recurrences that occurred 4 and 7 years after first tumour removal and matrix coagulation, 1 recurrence occurred 1 year after tumour removal that was accompanied by matrix coagulation in a patient with a diffuse anterocranial tumour extension and 1 occurred 3 years after tumour removal and durotomy. Two patients showed a small recurrence on MRI during follow-up after 2 and 5 years, respectively, without any symptoms requiring surgery. CONCLUSIONS: The high rate of favourable clinical results combined with the low rate of recurrences supports our less invasive surgical concept, which does not aim for resection of the dural matrix of the spinal meningioma.

Treatment strategies and outcome in patients with non-tuberculous spinal epidural abscess--a review of 46 cases.

OBJECTIVES: Spinal epidural abscess (SEA) is a rare disease and its early detection and appropriate treatment is essential to prevent high morbidity and mortality. There are only few single-institution series who report their experiences with the microsurgical management of SEA and treatment strategies are discussed controversially. Within the last 15 years the authors have treated 46 patients with SEA. This comparatively high number of cases encouraged us to review our experiences with SEA focussing on the clinical presentation, microsurgical management and outcome. METHODS: Clinical charts of 46 cases with a spinal epidural abscess treated between 1990 and 2004 were reviewed. There were 30 men and 16 women, the age ranged between 32 and 86 years (mean: 57 years). The clinical mean follow-up was 8.5 months (range: 2-84). The clinical presentation and severity of neurological deficits were measured by the Frankel grading system on admission and on follow-up visit. RESULTS: The abscess was located in the cervical spine in 8, the thoracic spine in 17 and the lumbar spine in 21 patients. On admission 8 patients were in Frankel grade A, 7 in B, 15 in C, 8 in D and 8 in E. During follow-up 1 patient was in Frankel grade A, 1 in B, 5 in C, 13 in D and 24 in E. 37 patients underwent primary microsurgery with abscess drainage or removal of chronic granulomatous tissue. The clinical symptoms in 4 patients worsened shortly after the operation due to a compression fracture of the vertebral body (n=2) or progress of the abscess (n=2) making re-operation necessary. 9 patients with severe critical illness or without neurological deficits had primarily a CT-guided puncture for assessment of the causative organism. 3 of them needed additional surgical therapy within the hospital stay because of a new neurological deficit. All patients were immobilised and treated with antibiotics for at least 6 weeks. The mortality was 6.5%. As for complications we noted septicaemia (n=5), meningitis (n=1) and a transient malresorptive hydrocephalus (n=1). CONCLUSION: Early diagnosis, microsurgical therapy with appropriate antibiotic therapy and careful observation of patients are the keys to successful management of SEA. The goal of surgical treatment is to isolate the causative organism and to perform a decompression at the site of maximal cord compression in cases of neurological deterioration or severe pain. Instrumentation with primary fixation does not seem to be imperative. In cases of post-operative worsening, a fracture of additionally infected bony elements has to be considered and a stabilisation should be discussed on an individual basis.

Ascites in hepatitis C liver transplant recipients frequently occurs in the absence of advanced fibrosis.

Ascites after liver transplantation is uncommon (3-7%) but causes morbidity and mortality. Although hepatitis C (HCV), pretransplant ascites, encephalopathy and cold ischemia time have been identified as predictors, neither posttransplant renal function nor the severity of recurrent HCV (inflammatory grade; fibrosis stage) has been systematically assessed. Among 173 HCV transplants (1 January 1998 to 31 December 2002), 18 patients (10%) developed posttransplant ascites. Cox proportional hazards models identified recipient female gender (hazard ratio [HR]= 12.18; p = 0.0001), cold ischemia time (HR = 1.17 per incremental hour; p = 0.021) and posttransplant creatinine (Cr) (HR = 1.56 per incremental 1.0 mg/dL; p = 0.0052) as independent predictors. Ludwig-Batts inflammation grade (HR = 1.32; p = 0.36) and fibrosis stage (HR = 1.63; p = 0.12) were not significant predictors. The 18 recipients had 19 ascites episodes; 12/19 had fibrosis stage 0, 1 or 2 (10/12 with stage 0 or 1). All 12 lacked diagnostic parenchymal or vascular histopathology. Renal function at ascites diagnosis were similar for transplants with fibrosis stage 0, 1 or 2 versus 3 or 4 (1.8 +/- 1.6 vs. 1.6 +/- 0.6 mg/dL; Cr clearance 39.6 +/- 15.6 vs. 39.3 +/- 13.4 mL/min/1.73 m(2)). In conclusion, recipient female gender, cold ischemia time and poor posttransplant renal function were independent predictors of ascites after HCV liver transplantation. Two thirds of ascites episodes, however, occurred without significant fibrosis or histopathology.

Role of central corneal thickness on baseline parameters and progression of visual fields in open angle glaucoma.

PURPOSE: To evaluate the relationship of central corneal thickness (CCT) to baseline visual field parameters and visual field progression in patients with primary open-angle glaucoma (POAG). METHODS: Charts of consecutive patients with POAG were reviewed to obtain visual field data. Visual field was measured by standard threshold static perimetry. Variables analyzed included mean deviation (MD) and pattern standard deviation (PSD). RESULTS: A total of 121 eyes examined over 4 years were evaluated. A significant negative relationship between CCT and PSD (correlation coefficient: -0.02, p<0.05) was found. Analyses comparing CCT to change in PSD and MD (visual field progression) were statistically not significant. CONCLUSIONS: Patients with thinner corneas initially present with a greater visual field defect, indicating that thin corneas may contribute to advanced glaucomatous damage at the time of diagnosis. However, CCT does not seem to be a significant risk factor for progression of the disease.

A randomized, placebo-controlled, double-blind clinical trial of curcuminoids in oral lichen planus.

We studied the efficacy of curcuminoids in the treatment of oral lichen planus (OLP), a chronic, mucocutaneous, immunological disease. Curcuminoids are components of turmeric (Curcuma longa) that have anti-inflammatory activity. Turmeric has been used in Ayurveda (Indian traditional medicine) for centuries. A randomized, double-blind, placebo-controlled trial was conducted. In all, 100 consecutive, eligible patients with OLP presenting to the oral medicine clinic at the University of California, San Francisco, were to be selected. Two interim analyses were to be conducted during the trial. The trial was conducted between February 2003 and September 2004. The first interim analysis was conducted in October 2004 using data from the first 33 subjects. Study subjects were randomized to receive either placebo or curcuminoids at 2000 mg/day for 7 weeks. In addition, all subjects received prednisone at 60 mg/day for the first 1 week. The primary outcome was a change in symptoms from baseline. Secondary outcomes were changes in clinical signs and occurrence of side effects. The first interim analysis did not show a significant difference between the placebo and curcuminoids groups. Conditional power calculations suggested a less than 2% chance that the curcuminoids group would have a significantly better outcome as compared with the placebo group if the trial were continued to completion. Therefore, the study was ended early for futility. Reaching a conclusion regarding the efficacy of curcuminoids based on the results of this study is not possible as it was ended early for futility. Curcuminoids at this dose were well tolerated and the results suggest that for future studies a larger sample size, a higher dose and/or longer duration of curcuminoids administration should be considered; however, for the next step, an RCT of a shorter duration, using a higher dose of curcuminoids, and without an initial course of prednisone, should be considered.

Are initial demyelinating event recovery and time to second event under differential control?

BACKGROUND: Relapsing-remitting multiple sclerosis (RRMS) begins with an initial demyelinating event (IDE) that can be monosymptomatic, polysymptomatic, or polyregional. Failure to recover from the IDE is a known predictor of later development of disability. Factors that predict IDE recovery (outside optic neuritis) and time to second event are relatively unknown. The authors speculate that IDE recovery and time to second event are under separate biologic or genetic control, and as such, their clinical predictors are different. METHODS: Data on all UCSF MS clinic patients are entered prospectively into an ACCESS database. The authors identified all patients seen at the UCSF clinic within 1 year of their IDE. Expanded Disability Status Scale scores, functional system scores, and visual acuity were used to define IDE severity and recovery. RESULTS: The cohort included 186 patients (127 women, 59 men) with an average onset age of 34 +/- 10 years with 150 whites (non-Hispanic), 15 African Americans, 11 Hispanics, eight Asians, and two unknown/unreported. Worse onset severity predicted worse IDE recovery (23.1% of the patients with severe onset vs 32.9% with moderate severity vs 56.4% with mild onset recovered completely, p < 0.001). Polyregional onset predicted poor recovery compared to monoregional onset (46.2% vs 14.4%, p < 0.001). Nonwhite patients were 2.48 times more likely than whites to experience a second episode within 1 year from onset (95% CI: 1.45 to 4.23, p < 0.001). Similarly, age younger than 30 years predicted higher risk of a second exacerbation (hazard ratio 1.92, 95% CI: 1.17 to 3.15, p = 0.010). CONCLUSION: Initial demyelinating event recovery and time to second event may have distinct predictors. These findings suggest that recovery and time to second event might be under separate biologic control.

Living donor kidney transplant recipients and clinical trials: participation profiles and impact on post-transplant care.

Many transplant physicians believe that transplant candidates who enroll in clinical trials may have better outcomes than those who do not enroll. We examined a 7-year cohort (1997-2003) of adult primary, non-HLA identical, living donor kidney transplant (LDKT) recipients to determine whether demographic characteristics predisposed to enrollment and whether participation affected posttransplant care intensity and/or allograft function. Overall, 146 of 512 (28.5%) LDKT recipients enrolled in clinical trials. LDKT recipients who were male and those who lived <100 miles from our transplant center were significantly more likely to participate. During the first post-transplant year, study patients (SPs) had more clinic visits (p < 0.0001) and more allograft biopsies (p = 0.024) compared to nonstudy patients (NSPs), but comparable numbers of hospital readmissions and allograft ultrasounds. SPs and NSPs did not differ in 1-year creatinine clearance, delta creatinine or rejection incidence. Overall graft and patient survival were comparable. We conclude that clinical trial participants were disproportionately male, had increased intensity of post-transplant care but comparable outcomes to nonparticipants.
