Background: Although numerous epidemiological studies have examined whether coffee consumption is associated with prostate cancer risk, the results remain controversial. Moreover, there are few studies in Asian populations. Therefore, we investigated the association between coffee consumption and the risk of prostate cancer in a large-scale prospective population-based cohort study in Japan. Methods: Study subjects were 48,222 men (40–69 years) who completed a questionnaire that included questions about their coffee consumption in 1990 for Cohort I and 1993 for Cohort II and were followed up until December 31, 2015. Newly diagnosed cases were classified into localized and advanced using information on local staging, the Gleason score, and degree of differentiation. Hazard ratios (HR) and 95% confidential intervals (95% CI) were estimated using Cox regression analysis. Results: A total of 1,617 participants were newly diagnosed with prostate cancer during a mean follow-up period of 18.8 years. Of these, 1,099 and 461 patients had localized and advanced cancer, respectively. There was no association between coffee intake and prostate cancer risk. Comparison between the highest and lowest category of coffee consumption produced HRs of 1.08 (95% CI, 0.90–1.30), 1.08 (95% CI, 0.84–1.38), and 1.00 (95% CI, 0.67–1.47) for risk of total, localized, and advanced cancer, respectively. The same results were obtained even when we limited the analysis to patients with subjective symptoms. Conclusions: Our findings suggest that coffee consumption has no impact on prostate cancer risk in Japanese men. Impact: Coffee has no protective effects against prostate cancer among Japanese men.

Hearing loss is the fifth leading cause of disability in the world. Coffee consumption might have a beneficial effect on hearing function because of the antioxidant and anti-inflammatory properties of some of its compounds. However, no previous longitudinal study has assessed the association between coffee consumption and the risk of hearing impairment.To assess the prospective association between coffee consumption and risk of disabling hearing impairment in middle and older men and women from the UK Biobank study.Analytical cohort with 36,923 participants (16,142 men and 20,781 women) [mean (SD): 56.6 (7.8) years, 1.6 (1.4) cups/d, and -7.6 (1.3) dB for age, total coffee consumption and speech reception threshold in noise at baseline, respectively]. At baseline, coffee consumption was measured with 3-5 multiple-pass 24-h food records. Hearing function was measured with a digit triplet test, and disabling hearing impairment was defined as a speech reception threshold in noise -3.5 dB in any physical exam during the follow-up. Analyses were stratified by sex and Cox regression models were used to assess the prospective association proposed.Over 10 years of follow-up, 343 men and 345 women developed disabling hearing impairment. Among men, compared with those who consumed1 cup/d of coffee, those who consumed 1, and ≥2 cups/d had a lower risk of hearing impairment (hazard ratio [95% confidence interval]: 0.72 [0.54-0.97] and 0.72 [0.56-0.92], respectively; P-trend: 0.01). This association was similar for caffeinated and decaffeinated coffee, and for filtered and non-filtered coffee, and was stronger in those with obesity (hazard ratio [95% confidence interval] for consumption of ≥2 vs.1 cups/d: 0.39 [0.21-0.74]). No association was found between coffee and hearing function among women.Coffee consumption was associated with lower risk of disabling hearing impairment in men but not in women. The association appeared to be independent of the coffee type and the preparation method.

Coffee drinking has been associated with decreased risk of some autoimmune diseases as well liver disease and outcomes. Environmental factors, such as coffee consumption, are yet to be assessed among patients with autoimmune hepatitis (AIH). We sought to investigate the relationship between coffee consumption and risk of AIH utilizing the Genetic Repository of Autoimmune Liver Disease and Contributing Exposures (GRACE) database. Lifetime coffee drinking was collected from 358 AIH patients (cases) and 564 volunteers (controls) from primary care visits. Groups were compared utilizing the Wilcoxon rank sum test for continuous variables and the Chi-square test for discrete variables. Logistic regression was used to analyze the effects of different coffee parameters (time, frequency, and cups) after adjusting for age, sex, education, smoking status, BMI, and daily activity. 24.6% of AIH patients never drank coffee compared to 15.7% of controls (p

Background Coffee consumption has been associated with a reduced risk of some cancers, but the evidence for renal cell carcinoma (RCC) is inconclusive. We investigated the relationship between coffee and RCC within a large cohort. Methods Coffee intake was assessed at baseline in the National Institutes of Health–American Association of Retired Persons Diet and Health Study. Among 420 118 participants eligible for analysis, 2674 incident cases were identified. We fitted Cox-regression models to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for coffee consumption vs non-drinkers. Results We observed HRs of 0.94 (95% CI 0.81, 1.09), 0.94 (0.81, 1.09), 0.80 (0.70, 0.92) and 0.77 (0.66, 0.90) for usual coffee intake of 10 years after baseline (HR 0.65, 95% CI 0.51, 0.82; Ptrend = 0.0005). Associations were similar between subgroups who drank predominately caffeinated or decaffeinated coffee (Pinteraction = 0.74). Conclusion In this investigation of coffee and RCC, to our knowledge the largest to date, we observed a 20% reduced risk for intake of ≥2 cups/day vs not drinking. Our findings add RCC to the growing list of cancers for which coffee consumption may be protective.

Most of the existing literature reports no association or a slight negative association between coffee consumption and the risk of developing breast cancer. However, the level of risk differs when considering various subgroups, such as menopausal status, hormonal status of the tumor or genetic mutations. The present review based on a literature search sets the point on the potential influence of a common daily drink, coffee, on the risk of developing breast cancer in the general population, in different subgroups of women and the consequences of drinking coffee after breast cancer has been diagnosed and treated. This review confirms that in the general population, there is no association between coffee intake and breast cancer risk or a slight protective effect, even at high dosages. Coffee is inversely associated with breast cancer risk in postmenopausal women and in women carrying a BRCA1 mutation. Possible risk differences exist between slow and fast caffeine metabolizers and with weight. Coffee consumption after breast cancer diagnosis and surgery, associated with tamoxifen and/or radiotherapy, reduced the occurrence of early events. The effects of coffee intake are less clear in other subgroups, mainly premenopausal women, women carrying a BRCA2 mutation and tumors with variable hormonal status (positive or negative for ER/PR) and would need additional studies.

Background: Coffee contains caffeine. Caffeine is the main component that influences the response of the cardiovascular system and blood pressure (BP). Acute response of coffee to increased BP is related to caffeine. Objectives: This study aims to analyze the acute response of coffee consumption on BP in healthy females therefore coffee is an alternative therapy for hypotension. Methods: The research design was a clinical trial. Treatment: black coffee, Gayo’s Arabica, 10 mg, coffee brewed with 150 ml of boiling water, without sugar. BP was examined using a mercury sphygmomanometer and stethoscope. BP each subject was examined twice and averaged. BP was checked 3 times: before, 30, and 60 minutes after coffee consumption. All subjects were non-coffee drinkers. A total of 20 healthy female, 18-20 years old were divided into two groups: the non-intervention (n=9) and intervention (n=11). Data was analyzed by independent and paired sample t-test. Results : Coffee increased systolic 10-20 mmHg (14.09%) and diastolic 3.64 mmHg. Coffee lowers 36.36% of subjects with hypotension. There was no difference between systolic pre-test (101.11±12.69 vs 100.00±10.00 mmHg; p=0.83) and 30 minutes post-intervention (102.22±13.01 vs 101.82±9.82 mmHg; p=0.94). There were a significant differences in systolic after 60 minutes post-intervention (103.33±11.18 vs 114.09±5.84 mmHg; p=0.01*) between non-intervention and intervention. There was no difference between diastolic pretest (70.00±5.59 vs. 68.18±6.03 mmHg; p=0.49), 30 minutes (70.59±5.27 vs. 70.00±6.33 mmHg; p=0.83), and 60 minutes post-intervention (70.00±5.59 vs. 71.82±4.04 mmHg; p=0.41) between non-intervention and intervention. Data showed that systolic was significantly different (p=0.00*) after 60 minutes of coffee consumption in the intervention group. Conclusion : The acute response of coffee consumption to systolic increases was after 60 minutes and not 30 minutes of coffee consumption. Coffee doesn’t affect diastolic in healthy women, but it needs further research.

Introdução: O consumo do café oferece várias ações benéficas no corpo humano, quando consumido em doses adequadas, dentre elas a ação anti-inflamatória, antioxidante e estimuladora do sistema nervoso central. Objetivo: O objetivo deste estudo foi avaliar o impacto do consumo de café na prevenção de melanoma. Material e Método: Foi realizada uma revisão bibliográfica nas bases de dados em saúde Medline, Lilacs e SciELO, utilizando os descritores em Ciências da Saúde (DeCS): nutrição; polifenóis; café; melanoma, nos idiomas português e inglês, considerando o período de junho de 2013 a junho 2020.

Palavras-chave: nutrição, polifenóis, café, melanoma.

Introduction and objectives: The prevalence of alcohol, tobacco, and coffee use and association with liver health among North Americans with Chronic Hepatitis B (CHB) infection has not been well described. Materials and methods: The Hepatitis B Research Network includes an observational study of untreated CHB adults enrolled at 21 sites in the United States and Canada. Alcohol use was categorized as none, moderate, and at-risk based on the definition from the National Institute on Alcohol Abuse and Alcoholism; tobacco use as never, current and former; coffee use as none, 1–2 cups/day, and ≥3 cups/day. Linear regression and linear mixed models were used to associate lifestyle behaviors with ALT and FIB-4 values. Results: 1330 participants met eligibility: 53% males, 71% Asian and the median age was 42 years (IQR: 34–52). Median ALT was 33 U/L (IQR: 22–50), 37% had HBV DNA

Green tea and coffee contain various bioactive compounds (e.g., polyphenols), and their consumption has been proposed to decrease the risk of cardiovascular diseases. Here, we investigated the associations between the consumption of green tea and that of coffee and the prevalence of coronary artery disease (CAD) in Japanese patients. The study group was 612 patients who underwent coronary angiography at Tokyo Medical Center between July 2008 and February 2017. CAD was confirmed in 388 of the patients: one-vessel disease (1-VD, n=166); two-vessel disease (2-VD, n=112); three-vessel disease (3-VD, n=110). Myocardial infarction (MI) was found in 138 patients. After adjustment for well-known atherosclerotic risk factors and other dietary habits, greater green tea consumption was significantly inversely associated with CAD prevalence (p for trend=0.044), and the patients who drank3 cups/d had a lower prevalence of CAD compared to those who drank1 cup/d (odds ratio [OR]: 0.54, 95% CI: 0.30-0.98). Greater green tea consumption (3 cups/d) was also associated with a decreased prevalence of 3-VD (OR: 0.49, 95% CI: 0.24-0.98, p-trend=0.047) and MI (OR: 0.51, 95% CI: 0.27-0.97, p-trend=0.037). In contrast, coffee consumption was not associated with CAD or MI. In subgroup analyses, the inverse association between green tea consumption and CAD or MI was found in the high intake groups of vegetables or fruits but not in the low intake groups of vegetables or fruits. These results suggest a beneficial effect of green tea consumption, especially with a diet rich in vegetables and fruits, against coronary atherosclerosis in Japanese.

Caffeine present in tea and coffee, the most commonly used beverages, has been implicated to have long term effects on cardiovascular system. The aim of this study was to document the acute and chronic effects of tea and coffee consumption on blood pressure, pulse wave velocity and aortic pressures in young, healthy individuals. This observational study was conducted on 86 healthy MBBS student volunteers of both genders between the age group of 18-27 years. Cardiovascular parameters (heart rate, peripheral blood pressure, central blood pressure, pulse wave velocity, augmentation pressure) were measured using PeriScope. Participants were divided into 3 groups based on their history of consuming tea/coffee/both/none. Data collected was analyzed using SPSS 17.0. ANOVA or Welsh test of equality of means was used for knowing the differences for scale variables. Paired sample t test was used to know the acute effect of coffee consumption among group 1 participants in a before-after design. In regular tea consumers, the bilateral brachial SBP, DBP and MAP were significantly higher than individuals who did not consume tea regularly; similar results in these parameters were also observed in regular coffee drinkers. However the lower limb arterial parameters were not markedly differently in tea/coffee group compared to non-drinkers. In both tea and coffee group, AoSP and AoDP were significantly higher than non-drinkers. Additionally, coffee drinking has acute stimulatory effects on CVS as evident by increase in peripheral and central vascular parameters.

Aim: Acute myocardial infarction (AMI) is the number one cause of death in 2000. Usually, coffee restriction was advised to patients with cardiovascular diseases. Recent studies indicate coffee might have a cardioprotective effect.Method: Systematic search was done on Pubmed and Cochrane. Title and abstract screening were initiated on 12 articles, followed by selection with inclusion and exclusion criteria, and selected one meta-analysis study to be critically appraised. Result: The meta-analysis study appraised resulted with a good score. Reduction in mortality rate was found, and an inverse relationship was concluded between heavy coffee consumption versus no consumption and mortality in acute myocardial infarction patients. RR = 0.54 95% CI [0.45 – 0.65].Conclusion: Coffee consumption and mortality in myocardial infarction patients have an inverse relationship, with the highest risk reduction found in heavy coffee drinkers.

Recent epidemiological studies have shown varying associations between coffee consumption and bladder cancer (BC). This research aims to elucidate the association between coffee consumption and BC risk by bringing together worldwide cohort studies on this topic. Coffee consumption in relation to BC risk was examined by pooling individual data from 12 cohort studies, comprising of 2601 cases out of 501,604 participants. Pooled multivariate hazard ratios (HRs), with corresponding 95% confidence intervals (CIs), were obtained using multilevel Weibull regression models. Furthermore, dose-response relationships were examined using generalized least squares regression models. The association between coffee consumption and BC risk showed interaction with sex (P-interaction 500 ml/day, equivalent to > 4 cups/day) coffee consumption compared to never consumers among male smokers (current smokers: HR = 1.75, 95% CI 1.27-2.42,P-trend = 0.002; former smokers: HR = 1.44, 95% CI 1.12-1.85,P-trend = 0.001). In addition, dose-response analyses, in male smokers also showed an increased BC risk for coffee consumption of more than 500 ml/day (4 cups/day), with the risk of one cup (125 ml) increment as 1.07 (95% CI 1.06-1.08). This research suggests that positive associations between coffee consumption and BC among male smokers but not never smokers and females. The inconsistent results between sexes and the absence of an association in never smokers indicate that the associations found among male smokers is unlikely to be causal and is possibly caused by residual confounding of smoking.

Introduction: Caffeine and its metabolites have antioxidant activity, scavenging reactive oxygen species. The aim of our study was to measure caffeine concentrations in vitreous samples after peroral caffeine intake. Methods: This prospective study included patients scheduled for 23-G pars plana vitrectomy with membrane peeling due to epiretinal membranes. The study was performed in two parts: in the first part, patients were recruited into three different groups: group A consisted of habitual coffee drinkers who agreed to drink coffee containing 180 mg caffeine 1 h before surgery (n = 10), group B consisted of habitual coffee drinkers who were not offered coffee before surgery (n = 5), and group C consisted of non-habitual coffee drinkers, forming the control group (n = 5). In the second part (group D) patients (habitual coffee drinkers) agreed to give additional blood serum samples for measurement of caffeine concentration. Harvested samples of vitreous (groups A–D), epiretinal membranes (groups A–C), and blood serum samples (group D) were examined for concentrations of caffeine with gas chromatography-mass spectrometry. Results: Samples of 40 eyes of 40 patients were harvested. The concentrations of caffeine in the vitreous samples were 1,998 ± 967 ng/mL in group A and 1,108 ± 874 ng/mL in group B. In group C, caffeine concentrations were below 176 ng/mL in all vitreous samples. Both groups A and B had significantly higher concentrations of caffeine in the vitreous samples than group C (p < 0.002, p < 0.01, Mann-Whitney U test). Caffeine concentrations in epiretinal membranes were below the limits of detection. Correlation of caffeine concentrations between blood serum samples and vitreous samples in group D was high, with significantly higher caffeine concentrations in the blood serum. Conclusion: Coffee consumption leads to significant caffeine levels in the vitreous compared to patients in the control group, and caffeine concentrations in the vitreous showed a high correlation to blood serum concentrations of caffeine after peroral coffee consumption.

BackgroundThe causal association between coffee consumption and the risk of OA is limited. This study was conducted to identify the potential causal effects of coffee consumption on total, knee, hip, and self-reported OA.MethodsGenome-wide association studies (GWAS) of OA were derived from the UK Biobank, comprising 50,508 participants of European ancestry (10,083 with cases and 40,425 controls), and genetic data for specific diagnosed knee OA (4462 cases and 17,885 controls), hip OA (12,625 cases and 50,898 controls), and self-reported OA (12,658 cases and 50,898 controls). Primary and secondary genetic instruments (11 SNPs and 8 SNPs) were selected as instrumental variants from GWAS among 375,833 and 91,462 participants. Two-sample Mendelian randomization (MR) analyses were performed to test the effects of the selected single nucleotide polymorphisms (SNPs) and the OA risk. The causal effects were primarily estimated using weighted median and inverse-variance weighted method with several sensitivity analyses.ResultsThe MR analyses suggested that genetically predicted 1% increase of coffee consumption was associated with an increased risk of overall OA (OR:1.009, 95% CI:1.003-1.016), knee OA (OR:1.023, 95% CI:1.009-1.038), self-reported OA (OR:1.007, 95% CI:1.003-1.011), but not hip OA (OR: 1.012, 95%CI:0.999-1.024) using primary genetic instruments. Similar results were found when using secondary genetic instruments that genetically predicted coffee consumption (cups/day). Additionally, the sensitivity analyses for leave-one-out methods supported a robust association between exposure traits and OA.ConclusionOur findings indicate that genetically predicted coffee consumption exerts a causal effect on total, knee, and self-reported OA risk, but not at the hip. Further research is required to unravel the role of coffee consumption in OA prevention.

One non-communicable disease that is still a major health problem in developing countries is hypertension; the prevalence of hypertension reaches 25.8%. Unhealthy lifestyle changes are one of the important factors that cause hypertension in the community. The study was conducted to obtain information about the relationship between physical activity, sleep quality, and coffee consumption habits with hypertension at the age of 45-65 years in the Belik Public Health Center, Pemalang Regency. The Case-Control approach was released in the study. The research target is people aged 45-65 years who seek treatment at Belik Public Health Center. The number of samples taken purposively was 100 respondents divided into 50 for the case group and 50 for the control group. The Chi-Square test was used to analyze the relationship between variables and the OR value to determine the contribution of the independent variables. The results showed that 75% had moderate physical activity, 74% had poor sleep quality, and 70% had low coffee consumption. Variables related to the incidence of hypertension were physical activity (P-value = 0.032, OR = 11) and sleep quality (P-value 0.006, OR = 3.765), while the coffee consumption variable was not related. Increasing exercise habits and regulating quality sleep patterns should be a priority for health promotion efforts in hypertension management programs. Keywords : Physical Activity, Hypertension, Coffee Consumption, Sleep Quality

Background There are conflicting reports on the association of coffee consumption with cardiovascular (CV) health. The UK Biobank is a prospective cohort study including data for half a million middle-aged individuals. Purpose We studied the association of daily coffee consumption with all-cause and CV mortality, and incidence of the major CV diseases in the UK Biobank. In a subgroup of participants who underwent cardiovascular magnetic resonance (CMR), we evaluated the association between regular coffee intake and cardiac structure and function parameters. Methods UK Biobank cohort of participants without clinically manifested heart disease at the time of recruitment were included. Regular coffee intake was categorized into 3 groups: zero, light-to-moderate (0.5–3 cups/day) and high (>3 cups/day) coffee drinkers. We estimated association of daily coffee consumption with incident outcomes using multivariable Cox-regression models (median follow-up of 11 years) and, in the subset with CMR data, with left and right ventricular (LV, RV) end-systolic and end-diastolic volumes, LV mass, and LV/RV stroke volume using multivariable linear regression. Models were adjusted for potential confounders and mediators, including: age, sex, non-European ethnicities, body mass index, smoking, physical activity, Townsend deprivation index, alcohol, meat, fruit and vegetable intake, hypertension, diabetes mellitus, and cholesterol level. Results We included 468,629 individuals (mean age 56.2±8.1 years, 44.2% male). Among them, 22.1% did not consume coffee on a regular basis, 58.4% had 0.5–3 cups per day and 19.5% had >3 cups per day. After adjustment for potential confounders and mediators, compared to non-coffee drinkers, light-to-moderate coffee drinking was associated with lower risk of all-cause mortality (HR=0.88, p Conclusion In this large study of the UK Biobank population, regular coffee consumption of up to 3 cups per day was associated with favorable cardiovascular outcomes, in particular, decreased all-cause and CV mortality and stroke incidence. Regular coffee consumption was also associated with a pattern of CMR metrics in keeping with the reverse of age-related cardiac alterations. Funding Acknowledgement Type of funding sources: None.

Introduction: Coffee, a popular and cheap beverage worldwide, may have an important effect on postoperative ileus (POI). However, previous systematic reviews have not clarified whether the effect is due to caffeine or coffee itself, or shortening hospital stay. We will aim to assess the effect of postoperative coffee consumption on POI. Methods: Studies evaluating the effect of postoperative coffee consumption will be searched using the electronic databases and the trial registries. Meta-analyses will be performed using random-effects models. The Grading of Recommendations, Assessment, Development, and Evaluation approach will be used to assess the certainty of evidence.

Background The aim of this study was to assess the associations of modifiable lifestyle factors (smoking, coffee consumption, sleep, and physical activity) and cardiometabolic factors (body mass index, glycemic traits, type 2 diabetes, systolic and diastolic blood pressure, lipids, and inflammation and kidney function markers) with risks of any (ruptured or unruptured) intracranial aneurysm and aneurysmal subarachnoid hemorrhage using Mendelian randomization. Methods and Results Summary statistical data for the genetic associations with the modifiable risk factors and the outcomes were obtained from meta‐analyses of genome‐wide association studies. The inverse‐variance weighted method was used as the main Mendelian randomization analysis, with additional sensitivity analyses conducted using methods more robust to horizontal pleiotropy. Genetic predisposition to smoking, insomnia, and higher blood pressure was associated with an increased risk of both intracranial aneurysm and aneurysmal subarachnoid hemorrhage. For intracranial aneurysm, the odds ratios were 3.20 (95% CI, 1.93–5.29) per SD increase in smoking index, 1.24 (95% CI, 1.10–1.40) per unit increase in log‐odds of insomnia, and 2.92 (95% CI, 2.49–3.43) per 10 mm Hg increase in diastolic blood pressure. In addition, there was weak evidence for associations of genetically predicted decreased physical activity, higher triglyceride levels, higher body mass index, and lower low‐density lipoprotein cholesterol levels with higher risk of intracranial aneurysm and aneurysmal subarachnoid hemorrhage, with 95% CI overlapping the null for at least 1 of the outcomes. All results were consistent in sensitivity analyses. Conclusions This Mendelian randomization study suggests that smoking, insomnia, and high blood pressure are major risk factors for intracranial aneurysm and aneurysmal subarachnoid hemorrhage.

Background: Observational studies have reported that coffee consumption was associated with Alzheimer’s disease (AD) and stroke risk. However, the results are inconclusive. Objective: We aimed to evaluate whether genetically predicted coffee consumption is associated with AD and stroke using Mendelian randomization (MR) design. Methods: Summary-level data for AD (n = 54,162), ischemic stroke (n = 440,328), and intracerebral hemorrhage (ICH, n = 3,026) were adopted from publicly available databases. Summary-level data for coffee consumption were obtained from two genome-wide association studies, comprising up to 375,833 subjects. Results: Genetically predicted coffee consumption (cups/day) was associated with an increased risk of AD (OR = 1.26, 95%CI = 1.05–1.51). Moreover, genetically predicted 50%increase of coffee consumption was associated with an increased risk of ICH (OR: 2.27, 95%CI: 1.08–4.78) but a decreased risk of small vessel stroke (OR: 0.71, 95%CI: 0.51–0.996). Estimate for AD and ICH in FinnGen consortium is directionally consistent. Combined analysis of different databases further confirmed that genetically predicted coffee consumption was associated with an increased risk of AD and ICH. In the multivariable MR analysis, genetically predicted coffee consumption retained a stable effect with AD and ICH when adjusting for smoking (p

Background: Recent studies have suggested a renal protective effect of coffee consumption against development of chronic kidney disease (CKD), although the results remain inconclusive. We performed a protocol for systematic review and meta-analysis to comprehensively investigate this association by summarizing all available data. Methods: An all-round retrieval will be performed in 5 electronic journal databases from their inception to June 2021, which comprise Medline, PubMed, Embase, ScienceDirect, and the Cochrane Library. The following key words were used on combination with Boolean operators AND or OR: “coffee,” “caffeine,” “renal insufficiency,” “chronic kidney diseases,” “chronic renal diseases.” Two authors completed the quality assessment using the Newcastle–Ottawa Scale for observational studies. The meta-analysis was conducted using Review Manager 5.3 software from the Cochrane Collaboration (London, UK). Results: The findings of this study will be submitted to peer-reviewed journals for publication. Conclusion: Coffee consumption may be associated with a lower risk of incident CKD.

Background/objectives: Amyotrophic lateral sclerosis (ALS) is a devastating and still untreatable motor neuron disease. The causes of ALS are unknown, but nutritional factors may impact the rate of disease progression. We aimed to ascertain the influence of coffee and tea consumption on ALS progression rate.Subjects/methods: In this multicenter cross-sectional study, we recruited 241 patients, 96 females, and 145 males; the mean age at onset was 59.9 ± 11.8 years. According to El Escorial criteria, 74 were definite ALS, 77 probable, 55 possible, and 35 suspected; 187 patients had spinal onset and 54 bulbar. Patients were categorized into three groups, according to their ΔFS (derived from ALS Functional Rating Scale-Revised score and disease duration from onset): slow (81), intermediate (80), and fast progressors (80).Results: Current coffee consumers were 179 (74.3%), 34 (14.1%) were non-consumers, and 22 (9.1%) were former consumers, whereas six (2.5%) consumed decaffeinated coffee only. The log-ΔFS was weakly correlated with the duration of coffee consumption (p = 0.034), but not with the number of cup-years, or the intensity of coffee consumption (cups/day). Current tea consumers were 101 (41.9%), 6 (2.5%) were former consumers, and 134 (55.6%) were non-consumers. Among current and former consumers, 27 (25.2%) consumed only green tea, 51 (47.7%) only black tea, and 29 (27.1%) both. The log-ΔFS was weakly correlated only with the consumption duration of black tea (p = 0.028) but not with the number of cup-years.Conclusions: Our study does not support the hypothesis that coffee or tea consumption is associated with the ALS progression rate.

The aim of this research was to determine the effect of coffee on creatinine and plasma malondialdehyde (MDA) level in rats fed on high purine diet. A total of 24 male Wistar rats divided into 4 groups of 6 rats each. Beef broth were given to 3 groups (K1, P1, P2) for thirty days. Beef broth administration were followed by giving coffee (caffeinated= P1 or by a decaffeinated= P2, 144 mg/200 g BW). Serum creatinine levels and plasma MDA were examined periodically on day 0, 15, and 30. Data were analyzed by multivariate analysis of variance or MANOVA test (CI= 95%, P0.05). Coffee administration (caffeinated and decaffeinated) may decrease the serum creatinine (day-30, K1= 3.17+ 0.69; P1= 1.63+0.11; P2= 1.14+0.08) and MDA levels (day-30, K1= 9.8+0.28; P1= 5.80+0.55, P2= 3.87+3.26) after 30 days of treatment (P= 0.000 for creatinine and MDA levels in K1, P1, P2 groups). A lower serum creatinine and MDA levels can be found in decaffeinated coffee grup. Coffee consumption for 30 days (especially decaffeinated) may decrease serum creatinine and plasma MDA in rat induced by a high purine diet.

Background: Coffee is a highly popular beverage worldwide, containing caffeine which is a central nervous system stimulant. Objectives: We examined whether habitual coffee consumption is associated with differences in brain volumes or the odds of dementia or stroke. Methods: We conducted prospective analyses of habitual coffee consumption on 398,646 UK Biobank participants (age 37–73 years), including 17,702 participants with MRI information. We examined the associations with brain volume using covariate adjusted linear regression, and with odds of dementia (4,333 incident cases) and stroke (6,181 incident cases) using logistic regression. Results: There were inverse linear associations between habitual coffee consumption and total brain (fully adjusted β per cup −1.42, 95% CI −1.89, −0.94), grey matter (β −0.91, 95% CI −1.20, −0.62), white matter (β −0.51, 95% CI −0.83, −0.19) and hippocampal volumes (β −0.01, 95% CI −0.02, −0.003), but no evidence to support an association with white matter hyperintensity (WMH) volume (β −0.01, 95% CI −0.07, 0.05). The association between coffee consumption and dementia was non-linear (P non-linearity= 0.0001), with evidence for higher odds for non-coffee and decaffeinated coffee drinkers and those drinking >6 cups/day, compared to light coffee drinkers. After full covariate adjustment, consumption of >6 cups/day was associated with 53% higher odds of dementia compared to consumption of 1–2 cups/day (fully adjusted OR 1.53, 95% CI 1.28, 1.83), with less evidence for an association with stroke (OR 1.17, 95% CI 1.00, 1.37, p = 0.055). Conclusion: High coffee consumption was associated with smaller total brain volumes and increased odds of dementia. Refereed/Peer-reviewed

OBJECTIVES: Given its popularity, there is an increasing interest in the study of coffee intake and its effect on health. Previous studies linked coffee consumption to lower type 2 diabetes (T2D) risk. However, potential underlying mechanisms remain unclear. We hypothesized that coffee's effects on systemic inflammation may play a role. We studied cross sectional and longitudinal associations of habitual coffee consumption with T2D risk and inflammation. METHODS: Participants from UK Biobank (UKB, n = 145,370) and Rotterdam Study (RS, n = 7172) cohorts were included. Coffee intake data were collected through self-administrated food frequency questionnaire or during home interviews. We studied associations of coffee intake with incident T2D using cox proportional hazard models; with longitudinally measured insulin resistance (HOMA IR) through linear mixed effect models; with serum baseline levels of inflammation markers using linear regressions; and the role of inflammation in coffee-T2D associations using mediation analysis. Models were adjusted for sociodemographic, lifestyle and health factors. Results were respectively expressed as hazard ratio (HR); β log transformed HOMA IR level; β log transformed ug/mL; and percentage mediated; and 95% confidence interval [95% CI]. RESULTS: UKB participants were 58% female and 55.2 years in average; RS were 59.7% female and 65.1 years. The median follow up was 7 (UKB) and 9 (RS) years. The modal coffee consumption was 0.5–2 cups/day (UKB) and 3–4 cups/day (RS). An increase of one coffee cup/day was associated with 4–6% lower T2D risk (RS HR 0.94 [95% CI 0.90; 0.98]; UKB HR 0.96 [0.94; 0.98]); lower HOMA IR (RS β −0.017 [−0.024; −0.010]); lower C reactive protein (CRP, RS β −0.014 [−0.022; −0.005]; UKBB β −0.011 [−0.012; −0.009] and higher adiponectin (RS β 0.025 [0.007; 0.042]. About coffee types, habitual consumers of filtered coffee had the lowest T2D risk (UKB HR 0.88 [0.83; 0.93]), compared to decaffeinated or instantaneous coffee. CRP levels mediated 9.6% (UKB) and 3.4% (RS) of the total effect of coffee on T2D. Adiponectin also showed evidence for mediation. CONCLUSIONS: Coffee's beneficial effects on lower T2D risk may be partially mediated by improvements in systemic inflammation. Among coffee drinkers, filtered coffee may be of preference.

Background Inconsistent associations between coffee consumption and bone mineral density (BMD) have been observed in epidemiological studies. Moreover, the relationship of bioactive components in coffee with BMD has not been studied. The aim of the current study is to identify coffee-associated metabolites and evaluate their association with BMD. Methods Two independent cohorts totaling 564 healthy community-dwelling adults from the Hong Kong Osteoporosis Study (HKOS) who visited in 2001–2010 (N = 329) and 2015–2016 (N = 235) were included. Coffee consumption was self-reported in an food frequency questionnaire. Untargeted metabolomic profiling on fasting serum samples was performed using liquid chromatography–mass spectrometry platforms. BMD at lumbar spine and femoral neck was measured by dual-energy X-ray absorptiometry. Multivariable linear regression and robust regression were used for the association analyses. Results 12 serum metabolites were positively correlated with coffee consumption after Bonferroni correction for multiple testing (P < 4.87 × 10–5), with quinate, 3-hydroxypyridine sulfate, and trigonelline (N’-methylnicotinate) showing the strongest association. Among these metabolites, 11 known metabolites were previously identified to be associated with coffee intake and 6 of them were related to caffeine metabolism. Habitual coffee intake was positively and significantly associated with BMD at the lumbar spine and femoral neck. The metabolite 5-acetylamino-6-formylamino-3-methyluracil (AFMU) (β = 0.012, SE = 0.005; P = 0.013) was significantly associated with BMD at the lumbar spine, whereas 3-hydroxyhippurate (β = 0.007, SE = 0.003, P = 0.027) and trigonelline (β = 0.007, SE = 0.004; P = 0.043) were significantly associated with BMD at the femoral neck. Conclusions 12 metabolites were significantly associated with coffee intake, including 6 caffeine metabolites. Three of them (AFMU, 3-hydroxyhippurate, and trigonelline) were further associated with BMD. These metabolites could be potential biomarkers of coffee consumption and affect bone health.

The present study was conducted to investigate whether the smell and sight of coffee (without tasting it) induced a conditioned response, and to compare the effect of the smell and sight of coffee in high- and low-consumption coffee drinkers. If classical conditioning caused the reduced reaction time effect, it was predicted that the degree of effect of caffeine-related stimuli would depend on the degree of experience of the pairing of conditioned stimulus (CS) and unconditioned stimulus (US). Sixty-six undergraduate students were randomly allocated to either a coffee or water presentation group and completed a simple reaction time task. Linear mixed modeling revealed that years of coffee consumption predicted reaction time when participants were presented coffee. The result coincided with the prediction that the greater the degree of experience of the pairing of CS and US, the greater the conditioned response would be. In conclusion, the present study showed that the smell and sight of coffee (without tasting it) induced a conditioned response and the direction was that of a caffeine-like effect. At least in behavioral effect, different types of caffeine CS uniformly induce a caffeine-like effect. Future studies should investigate the effect of the smell “or” sight of coffee to determine the relationship between CS type and direction of response.

Caffeine is the world's most popular 'drug', with tea and coffee a ubiquitous part of daily life. As a psychoactive stimulant, there are potential concerns regarding adverse cardiovascular squeal. Cardiovascular conditions, encompassing hypertension, coronary artery disease, rhythm disorders and heart failure affect billions of patients worldwide. We aim to provide a patient-centered comprehensive review of the cardiovascular effects of caffeinated beverages as they pertain to various common cardiovascular conditions. We conclude that intake of tea and coffee, particularly in moderate doses, does not appear to be harmful and may even be beneficial in a range of cardiovascular conditions, including coronary artery disease, heart failure and arrhythmias.

The relationship between coffee consumption and thyroid cancer (TC) occurrence has been evaluated in several observational studies with controversial results. The study aims to examine the associations between coffee consumption and TC occurrence. Systematic searches up to February 2019 were conducted. We estimated summary adjusted relative risks (RRs) and the corresponding 95% confidence intervals (CIs). The dose-response analysis was conducted by using generalised least square trend estimation. A total of ten studies involving 379,825 participants and 1,254 TC cases were included. The total summary RR showed that high coffee consumption was a protection factor of TC (RR = 0.75; 95% CI, 0.62-0.91). With the linear cubic spline model, the occurrence of TC was reduced by 5% with each one cup/day increment of coffee consumption (RR = 0.95; 95% CI, 0.91-0.99).This meta-analysis provides quantitative evidence that coffee consumption was inversely associated with the TC occurrence in a linear dose-response manner.

The association of habitual behaviors with the prevalence of synchronous colorectal cancer (sCRC) is unknown. Here, we investigated whether these behaviors, which are known risk factors for colorectal polyps, may be related to sCRC risk. We enrolled 17,093 patients who underwent cancer treatment between January 1995 and December 2016 and examined the association of age, sex, familial history of hereditary colorectal cancer (CRC), and status of three common habitual behaviors (smoking and alcohol and coffee consumption) with the prevalence of sCRC. Of the enrolled patients, 960 (5.6%) patients had sCRC. The independent risk factors for sCRC prevalence included advanced age, male sex, hereditary CRC, smoking, and daily alcohol consumption of more than one bottle (> 600 mL). Contrary to these factors, daily coffee consumption of more than one cup seemed to provide a protection from sCRC. In the Kaplan-Meier test, the significantly worse 5-year overall survival (OS) was noted in smokers with stage 0–III CRC. The effect of alcohol consumption on 5-year OS was significant in stages II and III. Compared with those without daily coffee consumption, patients with daily coffee consumption had significantly higher 5-year OS in stages I (93.0% vs. 86.4%), II (87.1% vs. 77.2%), III (71.5% vs. 61.9%), and IV (18.0% vs. 13.0%). sCRC prevalence was significantly associated with habitual behaviors. Patients with smoking or with daily alcohol consumption of one bottle had higher sCRC prevalence than did those without these habits. Coffee consumption could be a protective factor for lowering sCRC risk.

Background/Objective Dietary patterns may play an important role in the prognosis of heart failure. Methods Dietary habits, sleeping habits, physical activity and anxiety and depression status were recorded in 326 patients (90 females, mean age 73.45 ± 10.9 years) with ischemic heart failure prospectively followed for 30 months. Results Lower ΗADS-depression scores (p = 0.03), a low-fat meat diet (p = 0.035) and moderate coffee consumption (p = 0.005) were associated with better prognosis. Non-significant differences were recorded in outcomes with regard to consumption of other dietary categories. Conclusions A balanced diet as well as emphasis on the treatment of depression may improve outcomes in ischemic heart failure., Highlights • Coffee consumption is associated with better outcomes in ischemic heart failure. • A low fat meat diet is associated with better outcomes in ischemic heart failure. • High ΗADS depression score is related to worst prognosis in ischemic heart failure. • Sedentary lifestyle is related to worst outcomes in ischemic heart failure.

Diabetes mellitus (DM) is a chronic metabolic disease. It was caused by lack of insulin or cells cannot use insulin so that blood glucose becomes high (hyperglycemia). And it will cause other systemic diseases of the disease (metabolic syndrome) that can increase the factor of death. Coffee is one of the consumed plants that contain antioxidants and chlorogenic acid that have a role as antihyperglycemia. In other hand Jambi as one of the coffee producing regions (arabica, robust and liberica) in Sumatra and it has a potency as a coffee producer. In addition, people's habits in consuming coffee have the opportunity to be one solution in overcoming diabetes. This study aimed to determine the effect of hyperglycemia disease. The method was experimental with 5 treatments (metformin, arabica, robust, liberica and aquades) and 3 replications. Before threatments mice were injected with streptozotosin in order to be hyperglycemia, then mice with blood glucose ≥ 116 mg / dl were measured their blood glucose, weight and made the histology of the liver. Then the datas were analyzed using ANAVA. The results showed that Jambi coffee (arabica, robust and liberica) can lower blood glucose levels hyperglycemia mice until day 16. And the treatment with liberica coffee lowers hyperglycemia with the lowest glucose levels. While the histological features of mice liver showed lower cell degeneration especially in mice by coffee treatment, especially arabica coffee.

Background: Coffee intake has been linked to lower type 2 diabetes (T2D) risk. We hypothesized this may be mediated by coffee’s effects on inflammation. Methods: Using participants from the UK Biobank (UKB n=145370) and Rotterdam Study (RS n=7172) cohorts, we studied associations of coffee intake with incident T2D; longitudinally measured insulin resistance (HOMA IR); serum levels of inflammation markers; and the mediating role of inflammation. Statistical regression models were adjusted for sociodemographic, lifestyle and health factors. Results: The median follow up was 7 (UKB) and 9 (RS) years. An increase of one coffee cup/day was associated with 4-6% lower T2D risk (RS HR=0.94 [95% CI 0.90; 0.98]; UKB HR=0.96 [0.94; 0.98]); lower HOMA IR (RS β=-0.017 [-0.024; -0.010]); with lower C reactive protein (CRP) and higher adiponectin (Figure1). Consumers of filtered coffee had the lowest T2D risk (UKB HR=0.88 [0.83; 0.93]). CRP levels mediated 9.6% (UKB) and 3.4% (RS) of the total effect of coffee on T2D (Figure 1). Conclusions: We suggest that coffee’s beneficial effects on lower T2D risk are partially mediated by improvements in systemic inflammation.Figure 1. a CRP and a adiponectin refer to the effect of coffee intake on CRP and adiponectin levels. a CRP RS : β=-0.014 (-0.022; -0.005); UKBB a CRP UKB : β=-0.011 (-0.012; -0.009) and RS a adiponectin : β=0.025 (0.007; 0.042). b CRP and b adiponectin refer to the effect of coffee related levels in CRP and adiponectin on incident T2D, independent of coffee. RS b CRP : HR=1.17 (1.04; 1.31); UKB b CRP : HR=1.45 (1.37; 1.54); and b adiponectin : HR=0.58 (0.32; 0.83). c′ refers to coffee’ effect on T2D going directly or via others mediators. UKB c′ independent of CRP : HR=0.96 (0.94; 0.99); RS c′ independent of CRP : HR=0.94 (0.90; 0.99); and RS c′ independent of CRP+adiponectin : HR=0.90 (0.80; 1.01). Coffee related changes in CRP may partially explain the beneficial link between coffee and T2D, mediating a 3.4% (0.6; 4.8, RS) and 9.6% (5.7; 24.4, UKB). Evidence of mediation was also found for adiponectin.

Introducción: Caracterizar los pacientes con hipertensión arterial esencial y diabetes mellitus tipo 2 de la consulta externa. Métodos: Se realizó un estudio de único centro, transversal, en pacientes de la consulta externa de medicina interna del Hospital del Instituto Venezolano de los Seguros Sociales (IVSS) “Dr. Miguel Pérez Carreño”. Resultados: Se evaluaron 120 pacientes, donde el sexo femenino fue más frecuente con 65%, provenientes en su mayoría del Distrito Capital 83.33%. Un 39,1% eran jubilados y 55% estaban en normopeso. El promedio de PAS y PAD fue de 140 ±19,6 mmHg y 84 ±15,2 mmHg respectivamente. El 47,5% tenían prescripción con BRA. La duración de las enfermedades era >10 años, el consumo de café fue el hábito más destacado con 78,33%, y la mayoría eran sedentarios con 64,16% y los últimos seis mesas el evento medico más descrito fue el mareo con 27,56%. En un 85,84% de los casos con diabetes mellitus tipo 2 no estaban controlados. El 67% de los casos con diabetes mellitus tipo 2 encuestados consideran que su enfermedad no está bajo control, y los médicos conceptuaron que el 79,17% de los pacientes no tenían adecuado control. Conclusión: Se evidencia incumplimiento de las metas de control de los pacientes con HTA y DMT2, con un mayor predominio de esta última, y la presencia de factores de riesgo como el sedentarismo en un alto porcentaje

Metabolic syndrome (MetS) is prevalent not only among the overweight and obese but also normal weight individuals, and the phenotype is referred to as a metabolically unhealthy phenotype (MUHP). Besides normal weight individuals, overweight/obese individuals are also protected from MetS, and the phenotype is known as a metabolically healthy phenotype (MHP). Epidemiological studies indicate that coffee and micronutrients such as plasma folate or vitamin B12 (vit. B12) are inversely associated with MetS. However, correlations among coffee consumption metabolic phenotypes, plasma folate, and vit. B12 remain unknown. Our objective was to investigate the correlation between coffee consumption, metabolic phenotypes, plasma folate, and vit. B12 as well as to understand associations between plasma folate, vit. B12, and metabolic phenotypes. Associations among coffee consumption metabolic phenotypes, plasma folate, and vit. B12 were assessed in a cross-sectional study of 2201 participants, 18 years or older, from 2003–2004 and 2005–2006 National Health and Nutrition Examination Surveys (NHANES). MUHP was classified as having &gt, three metabolic abnormalities. Coffee consumption was not associated with metabolic phenotypes, but negatively correlated with several metabolic variables, including BMI (p &lt, 0.001). Plasma folate was positively associated with MUHP (p &lt, 0.004), while vit. B12 was inversely associated with MUHP (p &lt, 0.035). Our results suggest the potential protective impact of coffee on individual components of MetS and indicate a positive correlation between coffee consumption and MUHP among overweight individuals. Identifying possible dietary factors may provide practical and low-cost dietary intervention targets, specifically for early intervention. Larger and randomized intervention studies and prospective longitudinal studies are required to further evaluate these associations.

Coffee is widely consumed worldwide, and numerous studies indicate that coffee consumption may potentially affect the development of chronic diseases. Metabolic syndrome (MetS) may constitute a risk factor for chronic diseases. We aimed to prospectively evaluate the association between coffee consumption and MetS incidence. All participants were selected from the Health Examinees study. MetS was defined by the Adult Treatment Panel III criteria of the National Cholesterol Education Program. A multivariate Cox proportional hazards regression model was used to assess the relationship between coffee consumption and MetS incidence. In comparison with non-consumers, male moderate consumers (≤3 cups/day) showed a lower risk for low high-density lipoprotein cholesterol (HDL-C) (≤1 cup/day, hazard ratio (HR): 0.445, 95% confidence interval (CI): 0.254–0.780, 1–3 cups/day, HR: 0.507, 95% CI: 0.299–0.859) and high fasting blood glucose (FPG) (≤1 cup/day, HR: 0.694, 95% CI: 0.538–0.895, 1–3 cups/day, HR: 0.763, 95% CI: 0.598–0.972). Male 3-in-1 coffee (coffee with sugar and creamer) consumers also showed a lower risk for low HDL-C (HR: 0.423, 95% CI: 0.218–0.824) and high FPG (HR: 0.659, 95% CI: 0.497–0.874). These findings indicate a negative association between moderate coffee consumption and low HDL-C and high FPG among Korean male adults.

We conducted a Mendelian randomization study to assess whether alcohol and coffee consumption and smoking are causally associated with risk of developing migraine. Independent single-nucleotide polymorphisms associated with the potential risk factors at P5 × 10-8 in large-scale genome-wide association studies were selected as instrumental variables. Summary-level data for the associations of the selected single-nucleotide polymorphisms with migraine were obtained from the FinnGen consortium comprising 6687 cases and 144,780 noncases and the UK Biobank study comprising 1072 cases and 360,122 noncases. Estimates derived from the FinnGen and UK Biobank cohorts were combined using fixed-effects meta-analysis. We found evidence for associations of genetically predicted alcohol consumption (odds ratio [OR] 0.54 per SD increase in log-transformed alcoholic drinks per week, 95% confidence interval [CI], 0.35-0.82; P = 0.004), coffee consumption (OR 0.56 per 50% increase in coffee consumption, 95% CI, 0.45-0.70; P0.001), and smoking initiation (OR 1.15 for one SD increase in the prevalence of smoking initiation, 95% CI, 1.01-1.31; P = 0.038). These associations persisted in sensitivity analyses, including mutual adjustment in multivariable Mendelian randomization analyses. In reverse Mendelian randomization analyses, genetic liability to migraine was inversely associated with alcohol consumption but was not associated with coffee consumption or smoking initiation. This study provides genetic evidence in support of a protective role of moderate coffee consumption and a detrimental role of cigarette smoking in the etiology of migraine. The inverse association between alcohol consumption and migraine risk may be attributable to reverse causality.

To date, interest in the role of coffee intake in the occurrence and course of age-related neurological and neuropsychiatric disorders has provided an inconclusive effect. Moreover, no study has evaluated mocha coffee consumption in subjects with mild vascular cognitive impairment and late-onset depression. We assessed the association between different quantities of mocha coffee intake over the last year and cognitive and mood performance in a homogeneous sample of 300 non-demented elderly Italian subjects with subcortical ischemic vascular disease. Mini Mental State Examination (MMSE), Stroop Colour-Word Interference Test (Stroop T), 17-items Hamilton Depression Rating Scalfe (HDRS), Activities of Daily Living (ADL), and Instrumental ADL were the outcome measures. MMSE, HDRS, and Stroop T were independently and significantly associated with coffee consumption, i.e., better scores with increasing intake. At the post-hoc analyses, it was found that the group with a moderate intake (two cups/day) had similar values compared to the heavy drinkers (≥three cups/day), with the exception of MMSE. Daily mocha coffee intake was associated with higher cognitive and mood status, with a significant dose-response association even with moderate consumption. This might have translational implications for the identification of modifiable factors for vascular dementia and geriatric depression.

The aim of this study is to compare patients with and without mastalgia and to analyze the factors affecting mastalgia and its severity. The patient’s age, height, weight, educational status, marital status, and occupation were recorded in all subjects. In addition, the women were asked about the presence of any risk factors for mastalgia, such as tea and coffee consumption, smoking, alcohol consumption, and weight gain. The sternal notch to nipple distance (SNND) was measured to determine whether there was breast sagging. Mastalgia was significantly more common in women with BMIs of > 30 kg/m2 (OR: 2.94, CI 1.65–5.24), those who were primary school graduates or illiterate (OR: 2.96, CI 1.6–5.46), and those with SNND values of 22–25 cm (OR: 2.94, CI 1.79–4.82). In these women, drinking more than 6 cups of tea a day (OR: 2.15, CI 1.32–3.5), smoking at least 10 cigarettes a day (OR: 2.94, CI 1.78–4.83), and drinking alcohol at least once a week (OR: 2.1, CI 1.12–3.91) were found to be important factors that increased the risk of mastalgia. As a result, it has been found that severe mastalgia complaints cause by obesity, sagging breasts, never giving birth, unemployment anxiety, regular smoking, alcohol use, and excessive tea consumption.

Objective To determine the associations of smoking and alcohol and coffee consumption with pregnancy loss. Design Mendelian randomization study. Setting The UK Biobank study and FinnGen consortium. Patients A total of 60,565 cases with pregnancy loss and 130,687 noncases from UK Biobank and 3,312 cases with pregnancy loss and 64,578 noncases from FinnGen. Intervention(s) None. Mains Outcome Measure Pregnancy loss. Result(s) Genetic predisposition to smoking initiation was associated with an increased risk of pregnancy loss in both UK Biobank and FinnGen. The combined odds ratio (OR) was 1.31 (95% confidence interval [CI], 1.25–1.37) for one standard deviation increase in the prevalence of smoking initiation. There were no significant associations of genetically predicted consumption of alcohol (OR, 1.09; 95% CI, 0.93–1.27) or coffee (OR, 0.96; 95% CI, 0.87–1.06) with pregnancy loss. Conclusion(s) This study on the basis of genetic data suggests the causal potential of the association of smoking but not moderate alcohol and coffee consumption with pregnancy loss.

Objective This study aimed to evaluate and quantify the relationship between coffee and gastric cancer using a uniquely large dataset from an international consortium of observational studies on gastric cancer, including data from 18 studies, for a total of 8198 cases and 21 419 controls. Methods A two-stage approach was used to obtain the pooled odds ratios (ORs) and the corresponding 95% confidence intervals (CIs) for coffee drinkers versus never or rare drinkers. A one-stage logistic mixed-effects model with a random intercept for each study was used to estimate the dose-response relationship. Estimates were adjusted for sex, age and the main recognized risk factors for gastric cancer. Results Compared to never or rare coffee drinkers, the estimated pooled OR for coffee drinkers was 1.03 (95% CI, 0.94-1.13). When the amount of coffee intake was considered, the pooled ORs were 0.91 (95% CI, 0.81-1.03) for drinkers of 1-2 cups per day, 0.95 (95% CI, 0.82-1.10) for 3-4 cups, and 0.95 (95% CI, 0.79-1.15) for five or more cups. An OR of 1.20 (95% CI, 0.91-1.58) was found for heavy coffee drinkers (seven or more cups of caffeinated coffee per day). A positive association emerged for high coffee intake (five or more cups per day) for gastric cardia cancer only. Conclusions These findings better quantify the previously available evidence of the absence of a relevant association between coffee consumption and gastric cancer.

Ceramides are sphingolipids that play roles as structural lipids and as second messengers in biological processes. Circulating ceramides are influenced by diet/food and predict major cardiovascular (CV) events, such as atrial fibrillation (AF). In 1227 patients with symptomatic chronic heart failure (HF), an association between diet and ceramides was found for coffee consumption of ≥3 cups and Cer(d18:1/24:0). Increased Cer(d18:1/24:0) was associated with lower incident AF (24.3% vs 15.4% tertile 1 vs 3, P = 0.016) and lower CV mortality (28.4% vs 12.0% tertile 1 vs 3, P < 0.0001). For coffee consumption, only an association with incident AF was found (24.5% never, 5.2% ≥3 cups). These inverse associations with AF were confirmed in survival analyses corrected for biomarkers (Cer(d18:1/24:0) HR: 0.79, P = 0.018; coffee consumption HR: 0.22, P = 0.001). In conclusion, higher coffee intake was associated with a lower risk of incident AF and with higher concentrations of Cer(d18:1/24:0). Cer(d18:1/24:0) was inversely associated to risk of AF.

Introduction: Evidence on the associations of lifestyle factors with venous thromboembolism (VTE) is inconsistent. We aimed to investigate the associations of modifiable lifestyle factors with VTE in women and men. Methods: We used data from two cohorts comprising 30,137 women and 36,193 men aged over 45 years and free of cancer and VTE. Information on lifestyle factors was collected in 1997 via a self-administrated questionnaire. VTE cases were ascertained by linkage with the National Patient Register until the end of 2019. Results: During a mean of 16.9-years follow-up, 1784 women and 2043 men were diagnosed with VTE. Compared with individuals with 60 min/day, respectively. Compared with individuals with the lowest adherence to a modified Dietary Approaches to Stop Hypertension diet, the multivariable HRs of VTE were 0.87 (95% CI, 0.75, 0.99) and 0.88 (95% CI, 0.80, 1.00) for women and men with the highest adherence. In women, the multivariable HRs of VTE were 1.16 (95% CI, 1.03, 1.29) for past smoker and 1.28 (95% CI, 1.14, 1.45) for current smoker compared with never smoker. Alcohol and coffee consumption were not associated with VTE. Conclusions: This study suggests that being physically active and adhering to a healthy diet may lower the risk of VTE in women and men. Cigarette smoking was positively associated with VTE in women.
