Background: Renal replacement therapy (RRT) can be used to rewarm patients in deep hypothermia. However, there is still no clear evidence for the effectiveness of RRT in this group of patients. This systematic review aims to summarize the rewarming rates during RRT in patients in severe hypothermia, below or equal to 32 °C. Methods: This systematic review was registered in the PROSPERO International Prospective Register of Systematic Reviews (identifier CRD42021232821). We searched Embase, Medline, and Cochrane databases using the keywords hypothermia, renal replacement therapy, hemodialysis, hemofiltration, hemodiafiltration, and their abbreviations. The search included only articles in English with no time limit, up until 30 June 2021. Results: From the 795 revised articles, 18 studies including 21 patients, were selected for the final assessment and data extraction. The mean rate of rewarming calculated for all studies combined was 1.9 °C/h (95% CI 1.5–2.3) and did not differ between continuous (2.0 °C/h; 95% CI 0.9–3.0) and intermittent (1.9 °C/h; 95% CI 1.5–2.3) methods (p > 0.9). Conclusions: Based on the reviewed literature, it is currently not possible to provide high-quality recommendations for RRT use in specific groups of patients in accidental hypothermia. While RRT appears to be a viable rewarming strategy, the choice of rewarming method should always be determined by the specific clinical circumstances, the available resources, and the current resuscitation guidelines.

Background:Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAV) include granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA), and eosinophilic granulomatosis with polyangiitis (EPGA). Renal involvement is frequent in AAV and is an important factor for morbidity and mortality.Objectives:The main objective of this study was to analyze the demographic, clinical, histological and therapeutic characteristics of renal involvement in patients with AAV and the risk of renal replacement therapy (RRT) or death.Methods:Retrospective observational study of 56 patients with AAV fulfilling classificatory criteria and renal involvement diagnosed between 1995 and 2020 from a Spanish tertiary centre. We studied the histological involvement (according to the 2010 classification in focal, crescentic, mixed or sclerotic), immunofluorescence (IF) and the treatment received with the risk of RRT or death.Results:We included 56 patients diagnosed with AAV and renal involvement. The mean age was 61.08±4.05 years; 58.9% were women. The mean follow-up time of these patients was 16.14± 8.80 years. Only 57.1% of patients presented systemic involvement.Most frequent non-renal AAV manifestations were lung involvement (39.3%), central nervous system (30.4%), otorhinolaryngology (ORL) (14.3%), skin (8.9%) and cardiac involvement (8.9%). Main immunological findings were ANCA-MPO+ (69.6%), ANCA-PR3+ (23.2%), ANCA-negative (5.4%). Low C3 was found in 19.6% patients. Histologic classification (HC) and need of RRT is described in table 1. Main HC in renal AAV was crescentic, mixed, focal and sclerotic respectively. Eight patients had not biopsy performed. IF was positive for C3 deposits in 20 patients (35.7%). Half of the patients presented <50% normal glomeruli.The treatment of renal involvement in AAV in our cohort was as follows: 83.9% (47) corticosteroids (CS) and cyclophosphamide (of which 40 received intravenous and 7 oral cyclophosphamide; and 12 patients associated plasma exchange (PE) with this treatment), 5.36% CS alone, 2 patients received CS and mycophenolate; 1 CS and rituximab, 1 CS and PE, and 2 patients received no treatment. A total of 13 patients received PE and 18 RRT. The mean time to RRT was 65.44±32.72 months. Relapses were not uncommon, 33.93% of the patients presented ≥1 relapse and 10.71% presented ≥2.Infections were very frequent since they were present in 91.07% of the patients. Other frequent non-immunological complications observed in the follow-up of these patients were thrombosis in 31.14%, cardiovascular events in 28.57% and cancer in 19.64%.Patients with ANCA-PR3+ were younger at diagnosis (p<0.001), were more likely to present cardiac (p=0.045) and ORL involvement (p<0.001). However, neither ANCA-PR3+ nor ANCA-MPO+ were specifically associated with the need of RRT or higher risk of death in our cohort. Use of CS alone for the treatment of renal AAV was associated with higher mortality (p=0.006) but CS and cyclophosphamide with lower mortality (p=0.044). ANCA-negative patients were more likely to receive no treatment. Having <50% normal glomeruli and C3 deposits on IF were associated with an increased need for RRT. Presenting focal disease on HC was protective for the need of RRT. Older age at diagnosis, systemic involvement of AAV and need of RRT was associated with higher mortality.Conclusion:AAVs are complex vasculitides with frequent renal involvement. Increased C3 deposition, non-focal histological forms, and <50% normal glomeruli were related to the need for RRT. In turn, the need for RRT, a later age at diagnosis, and systemic involvement were associated with higher mortality. Holistic and multidisciplinary early management of AAVs in experience centers can help improve renal prognosis and decrease mortality.References:[1]Binda et al.

Background. The aim of this study was to perform a systematic review of the literature on the efficacy of antimicrobial photodynamic therapy (PDTa) on cariogenic dental biofilm.Types of Studies Reviewed. Studiesin vivo,in vitro, andin situwere included. Articles that did not address PDTa, those that did not involve cariogenic biofilm, those that used microorganisms in the plankton phase, and reviews were excluded. Data extraction and quality assessments were performed independently by two raters using a scale.Results. Two hundred forty articles were retrieved; only seventeen of them met the eligibility criteria and were analyzed in the present review. Considerable variability was found regarding the methodologies and application protocols for antimicrobial PDTa. Two articles reported unfavorable results.Practical Implications. The present systematic review does not allow drawing any concrete conclusions regarding the efficacy of antimicrobial PDTa, although this method seems to be a promising option.

Objectives: Determine if the peer-reviewed evidence supports single-patient ward bedrooms in low-acuity care settings within a hospital. Background: New evidence exists since the 2006 Facility Guideline Institute guideline recommended single-bedded rooms (SBRs) in low-acuity care settings. Additionally, prior studies evaluated high-acuity care settings (e.g., critical care) in their recommendations on SBRs. There is a need to reevaluate the evidence. Methods: A systematic review of the literature was completed including electronic and hand searches of references. A data extraction form was utilized. Two reviewers evaluated the studies independently. Studies that were included examined the effect of single-patient rooms on medical surgical ward beds only. Each study was graded using accepted clinical evidence grading instruments. Results: Over 1,400 records were identified. After excluding studies, a total of 49 records were graded. The highest quality evidence identified (Center for Evidence-Based Medicine [CEBM]: 2a, 2b, and Grading of Recommendations, Assessment, Development, and Evaluation [GRADE] C) did not support the use of single-patient rooms for reducing infections, for minimizing patient falls, for reducing medication errors, or for patient satisfaction. Operational efficiencies were improved with SBRs but only addressed the maternity ward. The lowest quality evidence (CEBM: 4/5 and GRADE D) supported the use of single-patient rooms. Conclusions: Based on CEBM and GRADE assessments, there is a lack of high-quality data supporting the use of low-acuity SBRs throughout the entire hospital. Furthermore, it is recommended that more research be conducted on the effect of SBRs, so higher quality evidence is developed.

Abstract Neurotoxicity due to cefepime has not been well characterized. We performed a systematic review of the literature and included 5 additional cases from our center. Of the 198 cases found, the mean age was 67 years and 87% of patients had renal dysfunction. The most common clinical features were diminished level of consciousness (80%), disorientation/agitation (47%), and myoclonus (40%). It is worth noting that nonconvulsive status epilepticus was relatively common with 31% of cases, whereas only 11% had convulsive seizures. Single-center estimate of incidence was 1 in 480 courses of cefepime. Cefepime neurotoxicity should be considered in older patients with renal dysfunction and new onset encephalopathy, especially if concurrent myoclonus is present. More work is needed to prospectively assess incidence and outcomes related to cefepime neurotoxicity.

Abstract Background Sepsis frequently leads to acute kidney injury. In severe cases, patients may require continuous renal replacement therapy (CRRT) which involves placement of a dialysis catheter and an extracorporeal blood filtration circuit. CRRT is commonly considered to “mask” fever, though this phenomenon has not been investigated. Methods We queried an institutional database of all patients on CRRT from 2007 to 2015 for inpatient temperature data and antibiotic administration records. Receipts of piperacillin–tazobactam, a carbapenem, or a third or fourth-generation cephalosporin, indicating a serious infection, were considered intervention arm. We analyzed temperatures recorded in the intensive care unit before, during, and after CRRT. Patients were divided into groups that did not receive antibiotics as well as those who did. Temperature data were Winsorized to correct for outliers. We also performed descriptive statistics for each group. Results There were 237,988 temperature readings for 1,568 ICU patients on CRRT. 1,153 patients received broad-spectrum antibiotics in ICU. In patients who received antibiotics in ICU and were presumed to have an infection, the mean temperature was 37.2°C prior to initiation of CRRT, 36.8°C while on CRRT, and 37.2°C following discontinuation of CRRT. In the 415 patients who did not receive IV antibiotics, the mean temperature was 36.9°C prior to initiation of CRRT, 36.6°C while on CRRT, and 37.0°C following discontinuation of CRRT. During each of the periods before, during, and after CRRT, patients who received antibiotics had significantly higher temperatures than those who did not (P < 0.001). Patients receiving antibiotics were generally younger (mean 60 years vs. 64 years, P < 0.001), had longer ICU stays (mean 29 days vs. 12 days, P < 0.001) and spent more time being ventilated (mean 23 days vs. 7 days, P < 0.001). The mean SOFA score on day one was similar (mean 11.1 in the antibiotic group and 10.5 in the other group). Conclusion This investigation suggests that patients have slightly lower temperatures while on CRRT, by on average less than half a degree. A similar effect is seen in both patients with infections as well as those without. Further work will be needed to determine what constitutes a true febrile response in this population.

INTRODUCTION: Acute kidney injury (AKI) is the sudden loss of renal function with accumulation of nitrogenous waste compounds. In developing countries, community acquired AKI is common than AKI in hospitalized septic patients. With conservative management many patients recover renal function however few require renal support with intermittent Hemodialysis (HD). We conducted a study to find out the etiology and outcome of the patients presenting with AKI who required dialysis.METHODS: This is a descriptive follow up study of the patients who needed renal replacement therapy in the form of HD presenting to our Nephrology unit of the hospital over a period of two years. Patients were followed up for three months post discharge. Data were tabulated and analyzed using SPSS software.RESULTS: Total 50 patients were included in study with 67% male. The commonest etiologies were urinary tract infection (30%) and  acute gastroenteritis (24%).The mean creatinine at the time of nephrology consultation, maximum level and at the time of discharge were 6.5(SD± 2.62), 7.3(SD ±2.13) and 2.2(SD ±1.75) respectively. Uremia with anuria was the most common reason for the initiation of HD in 54% cases. The mean number of intermittent HD used was 3.36. Complete recovery was seen in 68%, death in 26% and CKD in 6%.CONCLUSION: UTI followed by acute gastroenteritis are the leading cause of AKI in our tertiary level hospital. Timely initiated renal replacement therapy in the form of intermittent HD could lead to substantial renal recovery in almost three fourth of patients.
