RESUMO
OBJECTIVES: Binge spectrum disorders are prevalent worldwide. Psychiatric and medical comorbidities are common, and societal costs are significant. Evidence-based treatment remains underutilized. Cognitive behavioral therapy is the recommended first-line treatment, but pharmacotherapy may be easier to access. INTERVENTIONS: Meta-analytic evidence directly comparing cognitive behavioral therapy with pharmacotherapy is lacking. We aimed to compare the effects of cognitive behavioral therapy interventions with any pharmacological treatment for binge spectrum disorders. We searched PubMed, Embase, CENTRAL, ClinicalTrials.gov and reference lists for randomized controlled trials comparing cognitive behavioral therapy with any pharmacotherapy for bulimia nervosa/binge eating disorder and performed pairwise meta-analytic evaluations. PRIMARY OUTCOMES: Primary outcomes are remission and frequency of binges. Secondary outcomes are frequency of purges, response, eating disorder psychopathology, weight/body mass index, depression, anxiety, quality of life and dropouts. RESULTS: Eleven randomized controlled trials comparing cognitive behavioral therapy with fluoxetine/imipramine/desipramine/methylphenidate/sibutramine were identified (N = 531). Cognitive behavioral therapy was superior to antidepressants in terms of remission, frequency of binges and eating disorder psychopathology. There were no statistically significant differences for any of the individual cognitive behavioral therapy vs drug comparisons in terms of response/depression/anxiety/weight/quality of life/dropouts. Cognitive behavioral therapy was not superior to sibutramine/methylphenidate for the primary outcomes. CONCLUSIONS: Data are scarce, comparisons underpowered and, considering the inherent methodological limitations of psychotherapy trials, questions arise regarding the presumed superiority of cognitive behavioral therapy. Further research is needed.

Nonalcoholic fatty liver disease (NAFLD) has become the most common chronic liver disease in children and no medications or supplements are currently recommended. The role of omega-3 (n-3) fatty acids has been investigated in clinical trials with promising results. The aim of this study is to provide a detailed summary of the evidence about the efficacy of n-3 in the treatment of pediatric NAFLD. A systematic literature search was performed through major electronic databases up to September 20, 2021 for randomized placebo-controlled trials, investigating the efficacy of n-3 fatty acids in children with NAFLD. The primary outcomes were changes in serum transaminases concentration, Body Mass Index (BMI) and improvement of ultrasonographic liver steatosis. The secondary outcomes were changes in the patients' serum lipid profile, γ-glutamyl transferase (GGT), fasting blood glucose (FBG), homeostatic model assessment of insulin resistance (ΗΟΜΑ-ΙR) and waist circumference (WC). Results were expressed as mean differences for continuous outcomes and odds ratios for dichotomous outcomes with 95% confidence intervals. Six RCTs (n = 378 patients) were included. Treatment with n-3, compared to placebo, resulted in a statistically significant reduction in transaminases concentration. In addition, a significant improvement in liver steatosis assessed by ultrasonography and a decrease in BMI were observed. N-3 fatty acids supplementation seems to be an effective alternative treatment in pediatric NAFLD by improving liver biochemistry, ultrasonographic steatosis and BMI. Further research is required concerning the effect of n-3 fatty acids in liver histology.

OBJECTIVES: COVID-19 and the implementation of lockdowns have impacted daily lives worldwide. This systematic review and meta-analysis aimed to investigate the impact of lockdowns on the smoking and vaping behaviours of adults during the pandemic. STUDY DESIGN: This was a systematic review and meta-analysis. METHODS: A systematic literature search was conducted up to 28 April 2022 in the following databases: PubMed, Embase and Web of Science. RESULTS: In total, 77 studies met the inclusion criteria for this review. In 34 studies, an increase in smoking behaviour was reported for the majority of participants; however, in 21 and 18 studies, 'no change' and 'decrease' in smoking were the predominant responses, respectively. The results from the meta-analysis, which examined the change in the number of cigarettes smoked per day, showed no difference between the pre- and post-lockdown periods: 0.81 weighted mean difference (95% confidence interval, -0.59 to 2.21). Regarding vaping, three of seven studies reported an increase in smoking for the majority of participants, whereas 'no change' and 'decrease' were the predominant answers in the other four studies. CONCLUSIONS: The results show that lockdowns led most participants to increase smoking/vaping, whereas a decrease or cessation of smoking/vaping was only reported in the minority of participants. Attention should be given to the non-communicable diseases that could arise as a result of the increase in smoking/vaping during lockdowns, and further research in this area is needed.

OBJECTIVES: We conducted a systematic review and meta-analysis to provide a summary of the current literature about the efficacy of probiotics in pediatric nonalcoholic fatty liver disease (NAFLD). METHODS: A systematic literature search through major electronic databases was carried out for RCTs till September 9, 2021, investigating the efficacy of probiotics in the treatment of pediatric patients with NAFLD. Weighted mean differences (WMD) and Standard Deviations (SD) were used to calculate continuous outcomes and a Risk Ratio with 95% CI was used for dichotomous outcomes. RESULTS: In total, 4 RCTs with 238 pediatric patients with NAFLD were included in the study. Probiotic supplementation revealed a statistically significant difference in transaminases' levels (ALT: WMD = -7.51 IU/L, 95% CI, -11.28 to -3.73, I 2 = 0%, P < 0.0001; AST: WMD = -6.46 IU/L, 95% CI, -9.31 to -3.61, I 2 = 0%, P < 0.00001), anthropometric characteristics, total cholesterol, triglycerides and ultrasonographic steatosis improvement. CONCLUSIONS: According to the data of this meta-analysis, probiotic supplementation, and especially supplementation of Lactobacillus acidophilus in combination with other strains of Bifidobacterium or Lactobacillus may be beneficial in the improvement of transaminases', lipid parameters' levels, ultrasonographic, and anthropometric characteristics in children with NAFLD. Current evidence does not allow specifying the exact beneficial strain of probiotics mentioned above. The possible effect of probiotics on liver histology improvement in pediatric NAFLD should be examined in future studies.

BACKGROUND AND AIM: Νon-alcoholic fatty liver disease (NAFLD) is estimated to be the most common cause of end-stage liver disease in the next years. Vitamin E has shown beneficial effects as a possible "scavenger" of oxidative stress products, which play a major role in pathogenesis of the disease. The purpose of the present meta-analysis is to investigate the effects of vitamin E supplementation in biochemical and histological parameters in adult patients with NAFLD. METHODS: Literature search was performed in major electronic databases (MEDLINE, CENTRAL, and Embase) up to June 2020 for randomized clinical trials, which examined vitamin E versus placebo treatment in adults with NAFLD. Changes in liver enzymes were considered as primary outcomes while changes in histological, biochemical, and metabolic parameters as secondary. Quality of evidence was assessed through risk of bias according to the Cochrane risk of bias tool. RESULTS: Eight studies were included in qualitative analysis and seven in quantitative analysis. Vitamin E reduced the values of liver enzymes compared with placebo (-7.37 IU/L, 95% confidence interval: -10.11 to -4.64 for alanine aminotransferase, and -5.71 IU/L, 95% confidence interval: -9.49 to -1.93 for aspartate aminotransferase). Additionally, vitamin E improved statistically significantly liver pathology in every individual histological parameter as well as low-density lipoprotein cholesterol, fasting blood glucose, and serum leptin values. CONCLUSIONS: Vitamin E can improve biochemical and histological characteristics of NAFLD patients, especially of non-alcoholic steatohepatitis patients. The results indicate that vitamin E could be a promising choice and be considered as a treatment option in patients with NAFLD.

Chronic obstructive pulmonary disease (COPD) is characterized by high cardiovascular risk, which is further amplified during acute COPD exacerbations (AECOPD). Endothelial dysfunction has been previously suggested as one of the potential pathogenetic mechanisms. In order to study the effects of AECOPD on endothelial function assessed by available functional methods, we performed a literature search involving Pubmed and Scopus databases. Eligible studies were those that included adult patients with COPD and evaluated endothelial damage via semi-invasive or noninvasive functional methods, during AECOPD and after recovery or in stable condition. Newcastle-Ottawa Scale was applied to evaluate the quality of retrieved studies. Endothelial function was significantly impaired during AECOPD compared to recovery/stable condition (SMD: -0.87, 95%CI [-1.19, -0.55]). Patients during AECOPD presented a significantly worse response in endothelium-dependent (flow-mediated dilatation WMD: -2.59, 95%CI [-3.75, -1.42]) and independent vasodilation (nitroglycerine-mediated dilatation WMD: -3.13, 95%CI [-5.18, -1.09]) compared to recovery. Sensitivity analyses confirmed the above results. In conclusion, endothelium-dependent and independent vasodilation is worse during AECOPD compared to the stable condition. Endothelial dysfunction could play a role in the high cardiovascular risk during AECOPD.

Exercise during pregnancy may be beneficial provided that there are no contraindications. The aim of this study was to summarize and compare recommendations regarding exercise in pregnancy. Thus, a comparative descriptive review was conducted and included guidelines by the American College of Obstetricians and Gynecologists, the Society of Obstetricians and Gynaecologists of Canada and the Royal Australian and New Zealand College of Obstetricians and Gynaecologists. All compared guidelines recommend that pregnant women without contraindications should undertake physical activities regularly, however, the type of workout performed should be adjusted based on the previous exercise experience and the physical condition of each pregnant woman. A variation among the reviewed guidelines was identified on appropriate and inappropriate activities and on indications to interrupt exercise. To summarize, the adoption of an international up-to-date consensus regarding appropriate exercise during pregnancy may be beneficial in ensuring the safety of the pregnant women while promoting their physical and mental health.

BACKGROUND: Human epidermal growth factor-2 (HER2) overexpression is an oncogenic driver in many solid tumors, including urothelial bladder cancer (UBC). In addition, activating mutations in the ERBB2 gene have been shown to play an oncogenic role similar to ERBB2 amplification. OBJECTIVE: To describe and compare the frequency and nature of genomic alterations (GA) of ERBB2-altered (mutations, amplification) and ERBB2 wild-type UBC. PATIENTS AND METHODS: Using a hybrid capture-based comprehensive profiling assay, 9518 UBC cases were grouped by ERBB2 alteration and evaluated for all classes of genomic alterations (GA), tumor mutational burden (TMB), microsatellite instability (MSI), genome-wide loss of heterozygosity (gLOH), and genomic mutational signature. PD-L1 expression was measured by immunohistochemistry (Dako 22C3). Categorical statistical comparisons were performed using Fisher's exact tests. RESULTS: A total of 602 (6.3%) UBC cases featured ERBB2 extracellular domain short variant (SV) GA (ECDmut+), 253 (2.7%) cases featured ERBB2 kinase domain SV GA (KDmut+), 866 (9.1%) cases had ERBB2 amplification (amp+), and 7797 (81.9%) cases were ERBB2 wild-type (wt). European genetic ancestry of ECDmut+ was higher than ERBB2wt. Numerous significant associations were observed when comparing GA by group. Notably among these, CDKN2A/MTAP loss were more frequent in ERBB2wt versus ECDmut+ and amp+. ERBB3 GA were more frequent in ECDmut+ and KDmut+ than ERBB2wt. TERT GA were more frequent in ECDmut+, KDmut+, and amp+ versus ERBB2wt. TOP2A amplification was significantly more common in ECDmut+ and amp+ versus ERBB2wt, and TP53 SV GA were significantly higher in ERBB2 amp+ versus ERBB2wt. Mean TMB levels were significantly higher in ECDmut+, KDmut+, and amp+ than in ERBB2wt. Apolipoprotein B mRNA-editing enzyme, catalytic polypeptides (APOBEC) signature was more frequent in ECDmut+, KDmut+, and amp+ versus ERBB2wt. No significant differences were observed in PD-L1 status between groups, while gLOH-high status was more common in amp+ versus ERBB2wt. MSI-high status was more frequent in KDmut+ versus ERBB2wt, and in ERBB2wt than in amp+. CONCLUSIONS: We noted important differences in co-occurring GA in ERBB2-altered (ECDmut+, KDmut+, amp+) versus ERBB2wt UBC, as well as higher mean TMB and higher APOBEC mutational signature in the ERBB2-altered groups. Our results can help refine future clinical trial designs and elucidate possible response and resistance mechanisms for ERBB2-altered UBC.

BACKGROUND: Increasingly, chronic kidney disease (CKD) is becoming an inevitable consequence of obesity, metabolic syndrome, and diabetes. As the disease progresses, and through dialysis, the need for and loss of water-soluble vitamins both increase. This review article looks at the benefits and possible risks of supplementing these vitamins with the treatment of CKD. METHODS: Data in the PubMed and Embase databases were analyzed. The keywords "chronic kidney disease", in various combinations, are associated with thiamin, riboflavin, pyridoxine, pantothenic acid, folates, niacin, cobalamin, and vitamin C. This review focuses on the possible use of water-soluble vitamin supplementation to improve pharmacological responses and the overall clinical condition of patients. RESULTS: The mechanism of supportive supplementation is based on reducing oxidative stress, covering the increased demand and losses resulting from the treatment method. In the initial period of failure (G2-G3a), it does not require intervention, but later, especially in the case of inadequate nutrition, the inclusion of supplementation with folate and cobalamin may bring benefits. Such supplementation seems to be a necessity in patients with stage G4 or G5 (uremia). Conversely, the inclusion of additional B6 supplementation to reduce CV risk may be considered. At stage 3b and beyond (stages 4-5), the inclusion of niacin at a dose of 400-1000 mg, depending on the patient's tolerance, is required to lower the phosphate level. The inclusion of supplementation with thiamine and other water-soluble vitamins, especially in peritoneal dialysis and hemodialysis patients, is necessary for reducing dialysis losses. Allowing hemodialysis patients to take low doses of oral vitamin C effectively reduces erythropoietin dose requirements and improves anemia in functional iron-deficient patients. However, it should be considered that doses of B vitamins that are several times higher than the recommended dietary allowance of consumption may exacerbate left ventricular diastolic dysfunction in CKD patients. CONCLUSIONS: Taking into account the research conducted so far, it seems that the use of vitamin supplementation in CKD patients may have a positive impact on the treatment process and maintaining a disease-free condition.

BACKGROUND: The growing incidence of cancer globally, and the importance of nutrition support for these patients, emphasize the need for the development of nutritional clinical practice guidelines and consensus papers (CPGs) in the field. Numerous relevant CPGs have been published by several organizations worldwide. The aim of this systematic review was to compare the content of the existing CPGs and evaluate the quality of their development using the AGREE-II tool. METHODS: A systematic literature search in PubMed, Embase and Web of Science databases was conducted for the identification of relevant CPGs and consensus papers. Eligible CPGs was blindly evaluated by four appraisers according to the Appraisal of Guidelines for Research and Evaluation ΙΙ (AGREE-II) tool. RESULTS: In total 15 CPGs were identified and were evaluated. All but one set of CPGs underlined the importance of nutritional screening and assessment, whereas recommendations on nutritional interventions, supplements, management of complications and nutritional follow-up were also reported by several organizations. AGREE-II results showed that two CPGs were characterized as high, eight as moderate and five as low regarding their quality of development. CONCLUSIONS: Variety on recommendations could be observed between CPGs that should be considered when applied into clinical practice. Limitations of the existing CPGs could be the fact that they are non-specific and only a minority of them are focused to specific cancer types. Frequent updates for CPGs and inclusion of more nutritional topics should be considered for some CPGs. Improvement of the quality of the CPGs development should also be pursued in future.

Phase angle (PhA) and muscle strength are predictors of clinical outcomes in critically ill patients. Malnutrition may affect body composition measurements. The aim of this prospective study was to investigate the association between PhA and handgrip strength (HGS), and clinical outcomes in hospitalized COVID-19 patients. The study included a total of 102 patients. Both PhA and HGS were measured twice, within 48 h of hospital admission and on the 7th day of hospitalization. The primary outcome was the clinical status on the 28th day of hospitalization. Secondary outcomes included the hospital length of stay (LOS), the concentrations of ferritin, C-reactive protein and albumin, oxygen requirements and the severity of pneumonia. A one-way analysis of variance (ANOVA) test and Spearman rS correlation coefficient were used for statistical analysis. No differences were found for PhA [on day 1 (p = 0.769) and day 7 (p = 0.807)] and the primary outcome. A difference was found between HGS on day 1 and the primary outcome (p = 0.008), while no difference was found for HGS on day 7 (p = 0.476). Body mass index was found to be associated with the oxygen requirement on day 7 (p = 0.005). LOS was correlated neither with PhA (rs = -0.081, p = 0.422) nor with HGS (rs = 0.137, p = 0.177) on the first day. HGS could be a useful indicator of clinical outcomes in COVID-19 patients, while PhA does not seem to have a clinical impact. However, further research is needed to validate the results of our study.

Diabetes mellitus type 2 (DMT-2) presents with a growing incidence, and its complications contribute mainly to cardiovascular disease and overall mortality. DMT-2 prevention and early stage management include lifestyle modification by adopting healthy eating patterns and increasing physical activity levels. The Mediterranean diet (MD) is associated with beneficial effects on human health and has been found effective for preventing and managing DMT-2. The purpose of this meta-analysis is to investigate whether the level of MD adherence plays a role in DMT-2 prevention and to what extent. A systematic literature search in PubMed, EMBASE, Web of Science Core Collection, Scopus, and Google Scholar databases was conducted until November 2022, and related observational studies fulfilling the eligibility criteria were included. The literature search concluded with 24 studies in the qualitative analysis and 23 studies in the quantitative analysis. Of those, 18 cohort studies were eligible for meta-analysis with hazard ratio as effect size and five studies providing odds ratio as effect size. The cohort studies included 248,140 participants with a mean follow-up of 10.8 years (3 to 22 years). Individuals with high adherence to MD presented an 11% and 18% decrease in risk and odds, respectively, of developing DMT-2 compared to those with low MD adherence (HR 0.89, 95%CI 0.83 to 0.95) and (OR 0.82, 95%CI 0.72 to 0.93). In studies where the follow-up was longer than 10 years, the 12% decrease in the risk of developing DMT-2 remained (HR 0.88 95%CI 0.84 to 0.92), whereas in studies where follow-up was less than 10 years, no difference between groups with different levels of adherence was found. Long-term high MD adherence is associated with a reduced risk of developing DMT-2, but further studies are needed to confirm these results.
RESUMO
Background: Invasive infection with Streptococcus bovis/Streptococcus equinus complex (SBSEC) bacteria is associated with underlying colorectal neoplasia. However, the link between intestinal or fecal colonization with SBSEC isolates or antibody responses to SBSEC members and colorectal cancer is not thoroughly investigated in the literature. Methods: We searched the PubMed, EMBASE, and Web of Science databases for case-control studies as well as retrospective or prospective cohort studies reporting an association between SBSEC bacteria and colorectal neoplasia. Results: We identified 22 studies (15 case-control and 7 cohort) that met our inclusion criteria. Among the cohort studies, patients with SBSEC bacteremia were 3.73 times more likely to have underlying colorectal cancer compared with individuals with no bacteremia (relative risk [RR], 3.73; 95% CI, 2.79-5.01), whereas the risk of underlying colorectal adenoma in patients with SBSEC bacteremia was not significantly increased (RR, 5.00; 95% CI, 0.83-30.03). In case-control studies, patients with colorectal cancer were 2.27 times more likely to have evidence of intestinal or fecal colonization with SBSEC isolates (odds ratio [OR], 2.27; 95% CI, 1.11-4.62) and immunoglobulin G (IgG) antibody responses to SBSEC antigens (OR, 2.27; 95% CI, 1.06-4.86) compared with controls. Patients with colorectal adenoma were not more likely to be colonized with SBSEC isolates compared with controls (OR, 1.12; 95% CI, 0.55-2.25). Conclusions: Apart from the well-established association of SBSEC bacteremia and underlying colorectal cancer, intestinal or fecal colonization with SBSEC isolates and IgG antibody responses to SBSEC antigens were higher in patients with colorectal cancer compared with controls. Neither bacteremia from SBSEC isolates nor colonization with SBSEC bacteria was associated with underlying colorectal adenoma.
RESUMO
Bulimia Nervosa is a disorder with high rates of psychiatric and medical comorbidity and substantial societal costs. Cognitive Behavioural Therapy is considered the preferred treatment, but access can be problematic. Pharmacotherapy is more accessible but remains significantly underutilised. We aimed to assess the efficacy, tolerability, and safety of all available forms of pharmacotherapy for the treatment of bulimia nervosa. We conducted a comprehensive search of PubMed, EMBASE, CENTRAL, ClinicalTrials.gov, and reference lists of relevant articles up until April 2023. The primary outcomes were remission and binge frequency. 52 randomised controlled trials (RCTs) involving 3313 participants were included in the meta-analysis. Overall, no significant difference was observed between drugs and placebo in terms of remission; however, the available data were limited. Notably, drugs, particularly antidepressants, demonstrated a significant reduction in the frequency of binge episodes compared to placebo. Antidepressants were also found to be more effective than placebo in terms of treatment response and other clinically meaningful outcomes. An important limitation is that few RCTs were available for individual drugs. Our findings provide evidence supporting the increased utilisation of pharmacotherapy in clinical practice and underscore the need for further research involving larger populations and a broader range of outcomes.

OBJECTIVES: To examine patient and disease characteristics, toxicity, and clinical outcomes for patients with advanced urothelial carcinoma (aUC) who are rechallenged with immune checkpoint inhibitor (ICI)-based therapy. PATIENTS AND METHODS: In this retrospective cohort, we included patients treated with ICI for aUC after having prior ICI treatment. Endpoints included the evaluation of radiographic response and disease control rates with first and second ICI courses, outcomes based on whether there was a change in ICI class (anti-PD-1 vs. anti-PD-L1), and assessment of the reasons for ICI discontinuation. RESULTS: We identified 25 patients with aUC from 9 institutions who received 2 separate ICI courses. ORR with first ICI and second ICI were 39% and 13%, respectively. Most patients discontinued first ICI due to progression (n = 19) or treatment-related toxicity (n = 4). Thirteen patients received non-ICI treatment between the first and second ICI, and 12 patients changed ICI class (anti-PD-1 vs. anti-PD-L1) at rechallenge. Among 10 patients who changed ICI class, 8 (80%) had progressive disease as best response with second ICI, while among 12 patients re-treated with the same ICI class, only 3 (25%) had progressive disease as best response at the time of rechallenge. With second ICI, most patients discontinued treatment due to progression (n = 18) or patient preference (n = 2). CONCLUSIONS: A proportion of patients with aUC rechallenged with ICI-based regimens may achieve disease control, supporting clinical trials in that setting, especially with ICI-based combinations. Future studies are needed to validate our results and should also focus on identifying biomarkers predictive of benefit with ICI rechallenge.

BACKGROUND: Platinum-based chemotherapy (PBC) followed by avelumab switch maintenance in nonprogressors is standard first line (1L) treatment for advanced urothelial carcinoma (aUC). We describe clinical features and outcomes in a "real-world' cohort treated with avelumab maintenance for aUC. MATERIALS AND METHODS: This was a retrospective cohort study of patients (pts) who received 1L switch maintenance avelumab after no progression on PBC for aUC. We calculated progression-free survival (PFS) and overall survival (OS) from initiation of maintenance avelumab. We also described OS and PFS for specific subsets using Cox regression and observed response rate (ORR). RESULTS: A total of 108 pts with aUC from 14 sites treated with maintenance avelumab were included. There was a median of 6 weeks1-30 from end of PBC to avelumab initiation; median follow-up time from avelumab initiation was 8.8 months (1-42.7). Median [m]PFS was 9.6 months (95%CI 7.5-12.1) and estimated 1-year OS was 72.5%. CR/PR (vs. SD) to 1L PBC (HR = 0.33, 95% CI 0.13-0.87) and ECOG PS 0 (vs. ≥1), (HR = 0.15, 95% CI 0.05-0.47) were associated with longer OS. The presence of liver metastases was associated with shorter PFS (HR = 2.32, 95% CI 1.17-4.59). ORR with avelumab maintenance was 28.7% (complete response 17.6%, partial response 11.1%), 29.6% stable disease, 26.9% progressive disease as best response (14.8% best response unknown). CONCLUSIONS: Results seem relatively consistent with findings from JAVELIN Bladder100 trial and recent "real world" studies. Prior response to platinum-based chemotherapy, ECOG PS 0, and absence of liver metastases were favorable prognostic factors. Limitations include the retrospective design, lack of randomization and central scan review, and possible selection/confounding biases.

OBJECTIVES: Coronavirus disease 2019 (COVID-19) has emerged as a pandemic, affecting nearly 180 million people worldwide as of June 22, 2021. Previous studies have examined the association between the mean vitamin D (Vit D) concentration of each country and COVID-19 infection and mortality rate in European countries. The aim of the present study was to critically evaluate the relationship between prevalence of mild and severe Vit D deficiency in each country and COVID-19 infection, recovery, and mortality using updated data and a different methodological approach. METHODS: Information on Vit D concentration or deficiency for each country was retrieved through a literature search. COVID-19 infections and mortalities per million people and total recoveries, as of June 22, 2021, were obtained. The associations between Vit D deficiency and COVID-19 infection, recovery, and mortality were explored using correlation coefficients and scatterplots. RESULTS: Non-significant correlations were observed between both number of COVID-19 infections (r = 0.363, P = 0.116) and number of recoveries (r = 0.388, P = 0.091) and the prevalence of mild Vit D deficiency (<50 nmol/L). Similarly, non-significant correlations were observed between both infections (r = 0.215, P = 0.392) and recoveries (r = 0.242, P = 0.332) and the prevalence of severe Vit D deficiency (<30 nmol/L). Significant correlations were found between COVID-19 mortality and prevalence of both mild Vit D deficiency (r = 0.634, P = 0.003) and severe Vit D deficiency (r = 0.538, P = 0.021). CONCLUSIONS: The prevalence of neither mild nor severe Vit D deficiency was associated with the number of COVID-19 infections in European countries. Thus, it is an important parameter to consider when implementing preventive measures to face COVID-19.

The pandemic of coronavirus disease 2019 (COVID-19) and lockdown measures, that were implemented in many countries in order to control the virus transmission, had negatively influenced the lifestyle of millions of people worldwide. In this study we aimed to investigate the impact of the first COVID-19 lockdown period (March-May 2020) on snacking behavior, fast-food and alcohol consumption. A systematic search in PubMed®, Scopus® and Web of Science® databases was conducted and 32 studies were included. Changes in snacking, in fast-food and ordered food consumption and in alcohol intake were examined. Snacking was found to be increased for a significant portion of the population examined (18.9-45.1%), whereas fast food (15.0-41.3%) and ordered food (33.9%) showed a tendency towards decrease. As per alcohol consumption, an upward trend was observed in a significant part (10.4-51.0%) of the participants examined. The increased snacking and alcohol consumption observed for almost a third of the examined population could be alarming because long-term health problems could arise in cases of repeated lockdowns in the future. The observed downward trend in fast-food consumption and in frequency of ordered food could be an encouraging sign of turning to home-prepared foods, but further research is needed in this field.

BACKGROUND & AIMS: Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease in children and one of the leading indications for liver transplantation in adults. However, current screening methods are inadequate and are accompanied by several disadvantages. This meta-analysis aims to identify the anthropometrical and biochemical characteristics most commonly appearing in pediatric NAFLD that could contribute to the diagnosis of the disease in the every-day clinical setting. METHODS: A systematic search was conducted in major electronic databases (MEDLINE, Scopus and Embase) up to 15th of August 2021. Primary outcome was the comparison of the anthropometric characteristics, whereas secondary outcomes were the comparisons of biochemical profile, lipid profile, and metabolic parameters in children with NAFLD compared with age-matched healthy controls. Quality assessment was performed with Newcastle-Ottawa Scale (NOS) and results were expressed as mean differences with 95% confidence intervals. RESULTS: Sixty-four studies were included. Two different comparisons were designed regarding the body mass status. Statistically significant differences were demonstrated by comparing children with NAFLD vs lean/normal weighted controls in body weight (23.0 kg, 95% CI: 14.0-31.8, P < 0.00001), height (3.07 cm, 95% CI: 0.21-5.94, P = 0.04), ΒΜΙ (10 kg/m2, 95% CI: 8.36-11.7, P < 0.00001) and waist circumference 25.8 cm (95% CI: 20.6-30.9, P < 0.00001) and by comparing children with NAFLD vs overweight/obese controls in weight (6.81 kg, 95% CI: 3.81-9.81), height (3.18 cm, 95% CI: 1.24 to 5.13, P = 0.001), BMI (2.19 kg/m2, 95% CI: 1.76-2.62, P < 0.00001) and WC (7.35 cm, 95% CI: 6.20-8.49, P < 0.00001). CONCLUSIONS: Anthropometrical and biochemical characteristics of children and adolescents with NAFLD are statistically significantly different compared to age-matched controls; these characteristics could be used to identify individuals at risk of developing NAFLD and related comorbidities.
