Plain language summary
Osteoporosis is characterised by reduced bone mineral density and changes in bone metabolism, which may increase the risk of bone fractures. Elderly people are more at risk of developing osteoporosis. A calcium carbonate D3 tablet combined with nutritional intervention is commonly recommended by health professionals for the treatment of osteoporosis in the elderly. In this meta-analysis, 10 Chinese literature, 7 high-quality literature and 3 low-quality research were examined to determine the effect of nutritional intervention with calcium carbonate D3 tablets on changes in bone mineral density and bone metabolism in osteoporosis patients. Nutritional intervention in combination with calcium carbonate tablet supplementation showed significant efficacy compared to the use of a single drug. In the combined intervention group, osteocalcin levels, serum alkaline phosphatase levels, serum calcium levels, blood phosphorus levels, and bone mineral density were significantly higher than those in the monotherapy group. This study provides healthcare professionals with an opportunity to gain a better understanding of the efficacy of nutritional intervention coupled with calcium carbonate D3 supplementation on osteocalcin levels, serum alkaline phosphatase levels, serum calcium levels, blood phosphorus levels, and bone mineral density in osteoporosis patients. The validity of the data and the clinical utility of different combinations of therapeutic strategies require further robust research.
Abstract
To investigate the changes in bone mineral density, bone metabolism, and efficacy of nutritional intervention combined with calcium carbonate D3 tablets in patients with osteoporosis, a RevMan 5.2 software meta-analysis was conducted in this study. According to the therapeutic direction of nutritional intervention combined with calcium carbonate D3 tablets for osteoporosis patients, relevant literature were searched in Wanfang Medical, CNKI, VIP, and PubMed literature databases at home and abroad. Keywords included bone mineral density, bone metabolism, blood calcium (Ca), blood phosphorus (P), osteocalcin (OC), bone mineral density (BMD), serum alkaline phosphatase (ALP), efficacy, osteoporosis, and nutritional intervention. Literature that met the criteria were deleted, and meta-analysis was performed using RevMan 5.2 software. The results indicate that a total of 10 Chinese literature were included. Compared with the monotherapy group, the clinical efficacy, osteocalcin, BMD, alkaline phosphatase, calcium, and phosphorus were significantly higher in the combination group (P < 0.05). Based on calcium carbonate D3, treatment combined with nutritional intervention can enhance the clinical efficacy, bone metabolism, and bone mineral density of patients with osteoporosis, and nutritional intervention combined with calcium carbonate D3 tablets is a feasible program to promote the recovery of patients with osteoporosis.

Plain language summary
Coffee is one of the most consumed beverages worldwide. Coffee is a good source of polyphenolic antioxidant and anti-inflammatory compounds such as caffeine, cafestol, kahweol, and chlorogenic acids. This review included one hundred and five cohort studies and meta-analyses to evaluate the relationship between coffee consumption and cancer of the breast, liver, oesophagus, stomach, pancreas, colorectum, kidney, bladder, prostate, and ovaries. The results of this review found an inverse association between coffee consumption and reduced risk of hepatocellular cancer. A slight risk reduction is observed against breast cancer in postmenopausal women. This review found no considerable association between coffee consumption and decreased cancer risk in other organs. Further robust studies are required to investigate the benefits of coffee consumption on cancer risk reduction due to the high heterogeneity of included studies. However, healthcare professionals can use the results of this study to understand the benefits of coffee consumption.
Abstract
A significant number of studies suggest that coffee consumption reduces cancer risk. This beneficial effect is usually ascribed to the presence of polyphenolic antioxidants and anti-inflammatory agents, including caffeine, cafestol, kahweol, and chlorogenic acids. To summarize recent literature on this subject, we performed a bibliographic search in PubMed and Embase over the period January 2005 to December 2020 to identify cohort studies and meta-analysis (with data collection ensuring quality of selected reports) that could provide quantitative data on the relationship between coffee consumption and common cancers. The totality of eligible scientific articles supports the evidence that coffee intake is inversely associated with risk of hepatocellular cancer and, to a slight extent, risk of breast cancer among postmenopausal women. As to the association with other organs, including the esophagus, pancreas, colorectum, kidneys, bladder, ovaries, and prostate, the results are less clear as reports reveal conflicting results or statistically nonsignificant data. Therefore, this overview does not provide broad-based conclusions. Important uncertainties include general study design, inhomogeneous patient sampling, different statistical analysis (deliberate), misreporting of socioeconomic status, education, coffee-brewing methods, consumption of caffeinated or decaffeinated coffee, smoking habits, and alcohol intake. Clearly, more epidemiologic research needs to be conducted before solid science-based recommendations can be made with regard to coffee consumption.

Plain language summary
Caffeine is a well-documented ergogenic aid. Among the existing studies that have explored this topic, women are largely underrepresented in the data. The aim of this meta-analysis was to evaluate whether the ergogenic effects of caffeine on strength and endurance known to be true for men could also be extended to women. The analysis included studies that used women as participants and found caffeine to have a significant ergogenic effect on both endurance and strength. When a sub-group analysis differentiated between upper- and lower-body exercises independently, only upper-body performance was improved by caffeine ingestion. Based on the current literature, the authors conclude the ergogenic effects that were previously observed in men are also applicable to women. They suggest further investigation as to why the ergogenic effect differs between upper- and lower-body performance.
Abstract
This meta-analysis aimed to explore the effects of caffeine ingestion on muscular endurance and muscular strength in women. Five databases were searched to find relevant studies. A random-effects meta-analysis of standardized mean differences (SMD) was performed for data analysis. Subgroup meta-analyses explored the effects of caffeine on upper-body and lower-body muscular endurance and muscular strength. Eight crossover placebo-controlled studies were included in the review. In the main meta-analysis that considered data from all included studies, there was a significant ergogenic effect of caffeine on muscular endurance (SMD = 0.25; p = 0.027) and muscular strength (SMD = 0.18; p < 0.001). In a subgroup analysis that considered only upper-body exercises, there was a significant ergogenic effect of caffeine on muscular endurance (SMD = 0.20; p = 0.007) and muscular strength (SMD = 0.17; p < 0.001). In a subgroup analysis that considered only lower-body exercises, there was no significant difference between caffeine and placebo for muscular endurance (SMD = 0.43; p = 0.092) or muscular strength (SMD = 0.16; p = 0.109). The main finding of this meta-analysis is that caffeine ingestion has a significant ergogenic effect on muscular endurance and muscular strength in women. The effects reported in this analysis are similar to those previously observed in men and suggest that women may use caffeine supplementation as an ergogenic aid for muscular performance. Future research is needed to explore the effects of caffeine on lower-body muscular endurance and muscular strength in this population.

Plain language summary
Athletes commonly consume caffeinated drinks or supplements containing caffeine due to its ergogenic effect on performance. However, very few studies have investigated the effect of acute intake of caffeine on muscular performance in strength-trained women. This randomised, double-blinded, crossover trial examines the effect of acute intake of caffeine on maximal strength and local strength-endurance during the bench press exercise in women habituated to acute intake of caffeine. In this study, twenty-one healthy and strength-trained women were randomised to take 3 and 6 mg/kg/body mass acute caffeine intake. While both doses showed positive effects, this study also observed a dose-dependent (6 mg/kg body mass) significant increase in the response of acute intake of caffeine on maximal strength in women habituated to caffeine. The acute intake of caffeine at 6 mg/kg/body mass also increased the number of repetitions and time under tension during the bench press. The results of the study must be interpreted with caution due to a wide variation in caffeine habituation, resistance training levels, and strength exercise practices across the general population. Future robust studies are required to investigate this further. This study may help healthcare practitioners better understand the ergogenic effects of caffeine consumption in strength-trained habituated women.
Abstract
PURPOSE The main goal of this study was to assess the acute effects of 3 and 6 mg of caffeine intake per kg of body mass (b.m.) on maximal strength and strength-endurance in women habituated to caffeine. METHODS Twenty-one healthy resistance-trained female students (23.0 ± 0.9 years, body mass: 59.0 ± 6.6 kg), with a daily caffeine intake of 5.8 ± 2.6 mg/kg/b.m. participated in a randomized, crossover, double-blind design. Each participant performed three experimental sessions after ingesting either a placebo (PLAC) or 3 mg/kg/b.m. (CAF-3) and 6 mg/kg/b.m. (CAF-6) of caffeine. In each experimental session, the participants underwent a 1RM test and a strength-endurance test at 50 %1RM in the bench press exercise. Maximal load was measured in the 1RM test and the time under tension, number of preformed repetitions, power output and bar velocity were registered in the strength-endurance test. RESULTS The one-way ANOVA showed a main effect of caffeine on 1RM bench press performance (F = 14.74; p < 0.01). In comparison to the PLAC (40.48 ± 9.21 kg), CAF-3 (41.68 ± 8.98 kg; p = 0.01) and CAF-6 (42.98 ± 8.79 kg; p < 0.01) increased 1RM bench press test results. There was also a significant increase in 1RM for CAF-6 when compared to CAF-3 (p < 0.01). There was a main effect of caffeine on time under tension during the strength-endurance test (F = 13.09; p < 0.01). In comparison to the PLAC (53.52 ± 11.44 s), CAF-6 (61.76 ± 15.39 s; p < 0.01) significantly increased the time under tension during the maximal strength-endurance test. CONCLUSION An acute dose of 3-to-6 mg/kg/b.m. of caffeine improves maximum strength. However, these doses of caffeine had minimal ergogenic effect on strength-endurance performance in women habituated to caffeine.
