Review
Idiopathic nephrotic syndrome is the most frequent pediatric glomerular disease, affecting from 1.15 to 16.9 per 100,000 children per year globally. It is characterized by massive proteinuria, hypoalbuminemia, and/or concomitant edema. Approximately 85-90% of patients attain complete remission of proteinuria within 4-6 weeks of treatment with glucocorticoids, and therefore, have steroid-sensitive nephrotic syndrome (SSNS). Among those patients who are steroid sensitive, 70-80% will have at least one relapse during follow-up, and up to 50% of these patients will experience frequent relapses or become dependent on glucocorticoids to maintain remission. The dose and duration of steroid treatment to prolong time between relapses remains a subject of much debate, and patients continue to experience a high prevalence of steroid-related morbidity. Various steroid-sparing immunosuppressive drugs have been used in clinical practice; however, there is marked practice variation in the selection of these drugs and timing of their introduction during the course of the disease. Therefore, international evidence-based clinical practice recommendations (CPRs) are needed to guide clinical practice and reduce practice variation. The International Pediatric Nephrology Association (IPNA) convened a team of experts including pediatric nephrologists, an adult nephrologist, and a patient representative to develop comprehensive CPRs on the diagnosis and management of SSNS in children. After performing a systematic literature review on 12 clinically relevant PICO (Patient or Population covered, Intervention, Comparator, Outcome) questions, recommendations were formulated and formally graded at several virtual consensus meetings. New definitions for treatment outcomes to help guide change of therapy and recommendations for important research questions are given.

Meta-Analysis
BACKGROUND
In malnourished patients with colorectal cancer, hypoalbuminemia is common and was proposed to determine the postoperative outcome of colorectal surgery. Mounting articles published but have not been evaluated. We aim to assess the predictive value of preoperative hypoalbuminemia in patients undergoing colorectal surgery.
METHODS
We performed a literature search from PubMed, Euro PMC, and Cochrane with the terms serum albumin, hypoalbuminemia, prognosis, outcome, colorectal cancer, and neoplasm. We also hand-searched and included any relevant papers. Hypoalbuminemia is defined as plasma albumin level < 3.5 mg/dL. We restricted the included studies to English language and adults undergoing colectomy, laparotomy, laparoscopy, or abdominoperineal resection. Any types of articles were included, except an abstract-only publication and those that did not report the key exposure or outcome of interest. The key exposures were mortality, hospitalization time, and morbid conditions (thrombosis, surgical site infection, sepsis, and wound events). We pooled the odds ratio from each included literature as effect size. The Newcastle Ottawa scale and GRADE were used to determine the quality of each included study.
RESULTS
Hereof 7 observational studies (236,480 individuals) were included. Our meta-analysis found that preoperative hypoalbuminemia can predict the postoperative outcome in colorectal cancer patients. Individuals with hypoalbuminemia were not associated with 30-day mortality (risk ratio [RR] 2.05 [0.72, 5.86], P = .18, I2 = 99%) but were associated with morbidity (RR 2.28 [1.78, 2.93], P < .00001, I2 = 87.5%), surgical complication (RR 1.69 [1.34, 2.13], P < .00001, I2 = 98%), and hospitalization (RR 2.21 [1.93, 2.52], P < .00001, I2 = 0%). According to newcastle ottawa scale, the included studies are of moderate to sound quality.
CONCLUSIONS
The current systematic review and meta-analysis showed that preoperative hypoalbuminemia was significantly associated with morbidity, length of stay, and surgical complication but not mortality.

Review
OBJECTIVE
The current review was designed to explore if hypoalbuminemia is associated with increased complications in patients undergoing spinal degenerative and deformities surgeries.
METHODS
The search for eligible studies was conducted on the databases of PubMed, Embase, Web of Science, and CENTRAL up to 20th June 2022. Complication rates were pooled to obtain odds ratio (OR) and 95% confidence intervals.
RESULTS
Thirteen studies were included. We found that hypoalbuminemia was significantly associated with increased risk of all complications (OR: 2.72 95% CI: 2.04, 3.63 = 58% < 0.00001), mortality (OR: 7.73 95% CI: 3.81, 15.72 = 0% < 0.00001), revision surgery (OR: 3.15 95% CI: 1.53, 6.48 = 87% = 0.002), readmissions (OR: 1.96 95% CI: 1.29, 2.98 = 23% = 0.02), surgical site infections (OR: 2.97 95% CI: 1.90, 4.63 = 38% < 0.00001), wound complications (OR: 2.31 95% CI: 1.17, 4.56 = 48% = 0.02), pulmonary complications (OR: 3.74 95% CI: 2.66, 5.26 = 0% < 0.00001), renal complications (OR: 3.04 95% CI: 1.22, 7.54 = 0% = 0.02), cardiac complications (OR: 4.33 95% CI: 2.14, 8.77 = 0% < 0.0001), urinary tract infections (OR: 2.08 95% CI: 1.80, 2.41 = 0% < 0.00001), and sepsis (OR: 4.95 95% CI: 1.87, 13.08 = 64% = 0.01) as compared to those with normal albumin.
CONCLUSION
Hypoalbuminemia is a significant risk factor for complications after spinal degenerative and deformity surgeries. Research is also needed on the role of nutritional support in improving outcomes after spinal degenerative and deformity surgeries.

Review
INTRODUCTION
Postoperative pulmonary infections are associated with cough, phlegm, shortness of breath, chest pain, temperature above 38 degrees C, and pulse rate above 100 a minute. Up to half of people may have asymptomatic chest signs after surgery, and up to a quarter develop symptomatic disease. The main risk factor is the type of surgery, with higher risks associated with surgery to the chest, abdomen, and head and neck compared with other operations. Other risk factors include age over 50 years, chronic obstructive pulmonary disease (COPD), smoking, hypoalbuminemia, and being functionally dependent.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical question: What are the effects of interventions to prevent postoperative pulmonary infections? We searched: Medline, Embase, The Cochrane Library, and other important databases up to May 2007 (BMJ Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
RESULTS
We found 17 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
CONCLUSIONS
In this systematic review we present information relating to the effectiveness and safety of the following interventions: advice to stop smoking preoperatively, anaesthesia, lung expansion techniques, and postoperative nasogastric decompression.

Meta-Analysis
BACKGROUND
Coronavirus disease 2019 (COVID-19) elicits robust inflammatory reaction that may result in a declining albumin serum level. This meta-analysis aimed to evaluate the prognostic properties of hypoalbuminemia for poor prognosis and factors that may influence the relationship.
METHOD
A systematic literature search of PubMed was conducted from inception to April 22, 2021. The main exposure was albumin level below normal range-defined by the included studies. The outcome of interest was composite poor outcome that comprises of mortality, severity, and the requirement of mechanical ventilation or intensive care unit.
RESULTS
There were 6200 patients from 19 studies. Meta-analysis showed that hypoalbuminemia was associated with composite poor outcome (OR 6.97 (95% CI 4.20-11.55), p < 0.001; I = 91.3%, p < 0.001). Meta-regression analysis showed that age (p = 0.44), gender (p = 0.76), HT (p = 0.97), DM (p = 0.40), CKD (p = 0.65), liver disease (p = 0.72), and malignancy (p = 0.84) did not affect the association. Subgroup analysis showed that hypoalbuminemia increased mortality (OR 6.26 (95% CI 3.26-12.04), p < 0.001; I = 69.6%, p < 0.01) and severity of the disease (OR 7.32 (95%CI 3.94-13.59), p < 0.001; I = 92.5%, p < 0.01). Pooled diagnostic analysis of hypoalbuminemia yielded a sensitivity of 0.63 (95% CI 0.52-0.72), specificity of 0.81 (95% CI 0.73-0.87), and AUC of 0.77. The probability of poor outcome was 70% in patients with hypoalbuminemia and 24% in patients with normal albumin level.
CONCLUSION
Hypoalbuminemia was associated with poor prognosis in COVID-19 patients.

Review
The novel coronavirus SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) infection has been predominantly linked to respiratory distress syndrome, but gastrointestinal symptoms and hepatic injury have also been reported. The mechanism of liver injury is poorly understood and may result as a consequence of viral hepatitis, systemic inflammatory response, gut barrier and microbiome alterations, intensive care treatment or drug toxicity. The incidence of hepatopathy among patients with coronavirus disease 2019 (COVID-19) is unclear, but studies have reported liver injury in patients with SARS and Middle East respiratory syndrome (MERS). We aimed to systematically review data on the prevalence of hepatic impairments and their clinical course in SARS and MERS infections. A systematic literature search (PubMed/Embase/Cinahl/Web of Science) according to preferred reporting items for systematic review and meta-analysis protocols (PRISMA) was conducted from database inception until 17/03/2020 for studies that evaluated the incidence of hepatic abnormalities in SARS CoV-1, SARS CoV-2 and MERS infected patients with reported liver-related parameters. A total of forty-three studies were included. Liver anomalies were predominantly mild to moderately elevated transaminases, hypoalbuminemia and prolongation of prothrombin time. Histopathology varied between non-specific inflammation, mild steatosis, congestion and massive necrosis. More studies to elucidate the mechanism and importance of liver injury on the clinical course and prognosis in patients with novel SARS-CoV-2 infection are warranted.

Review
A systematic review and meta-analysis were carried out involving studies that compared the nutritional complications of Roux-en-Y gastric bypass (RYGB) and one-anastomosis gastric bypass (OAGB); these included the incidence of malnutrition as well as deficiencies of other nutritional elements, such as total protein, albumin, calcium and iron. A comprehensive search strategy was implemented in PubMed, Embase, and the Cochrane Library. Effect sizes included the pooled odds ratios (ORs) and 95% confidence intervals (95% CIs), as well as mean differences (MDs) and 95% CIs of the percentage total weight loss (%TWL) and excess weight loss percentage (%EWL). Thirteen studies were included (12,964 patients, 66.27% females, 53.82% underwent OAGB). At the longest follow-up period (≥3 years), OAGB was associated with significantly higher %TWL (MD=5.41%, 95%CI, 1.52 to 9.29) and %EWL (MD=13.81%, 95%CI, 9.60 to 18.02) compared to RYGB. However, OAGB procedures were associated with malnutrition (OR=3.00, 95%CI, 1.68 to 5.36, p<0.0001), hypoalbuminemia (OR=2.38, 95%CI, 1.65 to 3.43, p<0.0001), hypoproteinemia (OR=1.85, 95%CI, 1.09 to 3.14, p=0.022), anemia (OR=1.38, 95%CI, 1.08 to 1.77, p=0.011), and hypocalcemia (OR=1.78, 95%CI, 1.01 to 3.12, p=0.046). On subgroup analyses, the proportions of anemia and hypoalbuminemia remained significantly higher at longer follow-up periods and in studies published in Asia. Despite the favorable weight loss profile, the unfavorable nutritional consequences of OAGB merits further investigations to explore the malabsorptive element, ethnic variation, and the role of biliopancreatic limb length.

Review
Cognitive impairment is commonly observed in older adults with heart failure; nutrition is a possible contributing factor. The purpose of the current systematic review is to examine the relationship between nutrition and cognition in older adults with heart failure. A literature review was performed through August 2015 that examined published, peer-reviewed studies from PubMed, PsycINFO, CINAHL, and Web of Science. Four articles were selected for inclusion. Findings revealed that poorer nutritional habits were associated with poorer attention, executive functioning, and memory in older adults with heart failure. Nutritional biomarkers, including anemia, hyponatremia, hypokalemia, hyperglycemia, and hypoalbuminemia, were also associated with cognitive impairment. More research is needed to explore the relationship between nutrition and cognition in this population. Descriptive studies will inform scientists as they design and test nutritional interventions to optimize cognitive function in older adults with heart failure.

Hepatology International Sep 2020Liver function derangements have been reported in coronavirus disease (COVID-19), but reported rates are variable. (Meta-Analysis)
Meta-Analysis
BACKGROUND
Liver function derangements have been reported in coronavirus disease (COVID-19), but reported rates are variable.
METHODS
We searched PubMed and Embase with terms COVID and SARS-COV-2 from December 1, 2019 till April 5, 2020. We estimated overall prevalence, stratified prevalence based on severity, estimated risk ratio (RR), and estimated standardized mean difference (SMD) of liver function parameters in severe as compared to non-severe COVID. Random effect method utilizing inverse variance approach was used for pooling the data.
RESULTS
In all, 128 studies were included. The most frequent abnormalities were hypoalbuminemia [61.27% (48.24-72.87)], elevations of gamma-glutamyl transferase (GGT) [27.94% (18.22-40.27)], alanine aminotransferase (ALT) [23.28% (19.92-27.01)], and aspartate aminotransferase (AST) [23.41% (18.84-28.70)]. Furthermore, the relative risk of these abnormalities was higher in the patients with severe COVID-19 when compared to non-severe disease [Hypoalbuminemia-2.65 (1.38-5.07); GGT-2.31 (1.6-3.33); ALT-1.76 (1.44-2.15); AST-2.30 (1.82-2.90)]. The SMD of hypoalbuminemia, GGT, ALT, and AST elevation in severe as compared to non-severe were - 1.05 (- 1.27 to - 0.83), 0.76 (0.40-1.12), 0.42 (0.27-0.56), and 0.69 (0.52-0.86), respectively. The pooled prevalence and RR of chronic liver disease as a comorbidity was 2.64% (1.73-4) and 1.69 (1.05-2.73) respectively.
CONCLUSION
The most frequent abnormality in liver functions was hypoalbuminemia followed by derangements in gamma-glutamyl transferase and aminotransferases, and these abnormalities were more frequent in severe disease. The systematic review was, however, limited by heterogeneity in definitions of severity and liver function derangements. Graphical depiction of the summary of meta-analytic findings a) pooled prevalence of abnormalities b) Risk ratio of abnormality in severe versus non-severe COVID-19 c) standardized mean difference (SMD) between severe and non-severe group and d) pooled prevalence for parameters based on severity stratification for bilirubin, alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), albumin, globulin and acute hepatic injury (AHI) .

Meta-Analysis
BACKGROUND
Hypoalbuminemia is associated with fluid overload, the development of acute respiratory distress syndrome, and mortality. The co-administration of albumin and diuretics for the treatment of patients with hypoalbuminemia is expected to increase urine output, without hemodynamic instability, and improve pulmonary function; however, these effects have not been systematically investigated. Here, we aimed to clarify the benefits of the co-administration of albumin and diuretics in mechanically ventilated patients.
METHODS
We searched for randomized, placebo-controlled trials that investigated the effects of the co-administration of albumin and diuretics compared with placebo and diuretics, in mechanically ventilated patients with hypoalbuminemia. We searched these trials in the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE via PubMed, and EMBASE databases. Primary outcomes were hypotensive events after the intervention, all-cause mortality, and the length of mechanical ventilation. Secondary outcomes were improvement in the ratio of partial pressure arterial oxygen and fraction of inspired oxygen (P/F ratio) at 24 hours, total urine output (mL/d), and the clinical requirement of renal replacement therapy (RRT).
RESULTS
From the 1574 records identified, we selected 3 studies for quantitative analysis. The results of albumin administration were as follows: hypotensive events (risk ratio [RR] -1.05 [95% confidence interval {CI}: 0.15-0.81]), all-cause mortality (RR 1.0 [95% CI: 0.45-2.23]), the length of mechanical ventilation in days (mean difference -1.05 [95% CI: -3.35 to 1.26]), and improvement in P/F ratio (RR 2.83 [95% CI: 1.42-5.67]). None of the randomized controlled trials reported the total urine output, and one reported that no participants required RRT. Adverse events were not reported during the trials. The certainty of evidence was low (in the hypotensive events after the intervention and all-cause mortality) to moderate (in the length of mechanical ventilation in days, improvement of P/F ratio, clinical requirement of RRT, and adverse events).
CONCLUSIONS
Although this treatment combination reduced the number of days for which mechanical ventilation was required, it did not reduce the all-cause mortality at 30 days. In conclusion, the co-administration of albumin and diuretics may reduce hypotensive events and improve the P/F ratio at 24 hours.
