The aim of this study was to assess the available evidence regarding the effect of a variety of fasting-like regimens on preventing chemotherapy-related side effects. PubMed, Scopus and Embase were used to select the studies for this review, which concluded on 24 November 2022. All types of clinical trials and case series reporting chemotherapy toxicity associated with fasting regimens and any comparison were considered. A total of 283 records were identified, of which 274 were excluded, leaving only nine studies that met the inclusion criteria. Five of these trials were randomized. Overall, moderate to high-quality evidence showed that several fasting regimens did not provide benefits compared to a conventional diet or other comparators in reducing the risk of adverse events. The overall pooled estimate for a variety of fasting regime when compared to non-fasting, indicated no significant difference in the side effects (RR = 1.10; 95% CI: 0.77–1.59; I² = 10%, p = 0.60), including neutropenia alone (RR = 1.33; 95% CI: 0.90–1.97; I² = 0%, p = 0.15). A sensitivity analysis confirmed these results. Based on our systematic review and meta-analysis, there is currently no evidence supporting the superiority of therapeutic fasting over non-fasting in preventing chemotherapy toxicity. The development of cancer treatment that do not entail toxicities remains imperative.

Purpose: Previous studies have reported on the outcomes of autologous chondrocyte implantation (ACI) versus matrix‐induced ACI (MACI) and microfracture. Specific clinical outcomes of ACI, MACI, osteochondral autograft transplantation (OAT) and osteochondral allograft (OCA) have not been well studied. The purpose of this systematic review and meta‐analysis was to analyze the outcomes of these regenerative surgical techniques with an emphasis on comparing their effectiveness using the International Knee Documentation Committee (IKDC) subjective score, the Lysholm Knee Scoring Scale, the Tegner Activity Scale and the Visual Analogue Scale (VAS) score for the surgical treatment of tibiofemoral joint cartilage defects.Methods: An electronic search of MEDLINE, Embase and Cochrane Library was performed to identify studies that reported clinical outcomes for ACI, MACI, OAT and OCA procedures. The literature review was conducted following Preferred Reporting Items for Systematic Reviews and Meta‐Analyses guidelines and only studies involving cartilage defects in the tibiofemoral joint were included. Outcomes were measured with the IKDC evaluation, Lysholm Knee Scoring Scale, Tegner Activity Scale and the VAS. Outcomes were compared to the minimal clinically important difference (MCID) and patient acceptable symptom state (PASS). The methodological quality of the included studies was analyzed by the Methodological Index for Nonrandomized Studies and the Jadad scale.Results: Forty‐seven studies were included representing a total of 1993 patients with a mean follow‐up time of 57.2 ± 40.3 months (range: 4.0–160.0 months). The location of cartilage defects was reported in 46 studies, with a total of 1922 cartilage defects. There were 1277 medial femoral condyle cartilage defects, 488 lateral femoral condyle cartilage defects, 139 unspecified femoral condyle cartilage defects and 18 tibial plateau cartilage defects. All four procedures reported significant improvements in the Lysholm, IKDC, Tegner and VAS scores with no significant differences between them. The OAT technique surpassed the PASS threshold for the IKDC score while all four techniques surpassed the PASS threshold for Tegner and Lysholm scores. Additionally, all procedures met the MCID for each clinical outcome.Conclusion: This systematic review and meta‐analysis indicate that ACI, MACI, OAT and OCA all result in significant improvements in knee function and pain for cartilage defects of the tibiofemoral joint. When selecting a procedure, patient and cartilage defect characteristics should be assessed to determine the best technique for each individual patient.Study Design: Systematic review and meta‐analysis.Level of Evidence: Level III.

Growing evidence has revealed the pivotal role of inflammatory biomarkers in the pathogenesis of osteoarthritis. There is significant interest in the prognostic value of select biomarkers, given the potential for early identification and treatment of patients at risk of osteoarthritis prior to the development of irreversible clinical disease. Clinical trials of novel therapeutics that disrupt the inflammatory pathways of osteoarthritis are also ongoing. The purpose of this review is to summarize the current literature on key biomarkers within the context of osteoarthritis pathogenesis, clinical symptom development, and treatment capabilities. Multiple recent studies have established biomarkers that signal the existence of osteoarthritis pathology and the development of clinical symptomology. However, prior to implementation in clinical practice, additional research is required to precisely define the prognostic value for numerous biomarkers and standardize their measurement. Biomarker-driven investigations represent a promising avenue for the early diagnosis and treatment of osteoarthritis.

Background: The condition of vitamin D (25OHD) deficiency represents an important public health problem. In Europe, hypovitaminosis is common not only in the elderly population but also between 50 and 70 years, both in males and females. Data regarding vitamin D intake in the Italian population are very limited. In a recent paper, reporting data collected by a specific Frequency Food Questionnaire (FFQ), we observed in a small group of healthy subjects that the dietary consumption of vitamin D, both in females and males, was far below the average. Methods: With the aim of expanding our preliminary data, we conducted a survey on a large cohort of subjects from different areas of Northern, Central, and Southern Italy. The FFQ contained 11 different questions regarding the amount and type of intake of foods containing ergocalciferol and cholecalciferol. It was submitted to 870 subjects, 627 females and 243 males, with an age range from 40 to 80 years; 31.6% of the studied population was apparently in good health, while 68.4% were affected by different pathologies. Results: The present data confirm previous observations: the global quantity of vitamin D intake in 14 days was 70.8 μg (±1.8 SE, ±54.4 SD) in females and 87.5 μg (±1.9 SE, ±57.1 SD) in males; the mean daily intake of vitamin D in females and males was 5.05 μg (±0.5 SE, ±3.8 SD) and 6.25 μg (±0.21 SE, ±4.1 SD), respectively. In healthy subjects, a gradual decrease was observed in the overall intake of vitamin D in both females and males according to an increase in age bracket, ranging from 74.5 μg and 103.8 μg in the 40–50 age group to 54.5 μg and 87.8 μg in the 71–80 age group, respectively. Conclusions: In conclusion, the present data, collected in a large Italian cohort, underscore that the daily intake of vitamin D is far below the recommended daily average, thereby contributing to the development of potential hypovitaminosis.
