Canned Fish Consumption and Upper Digestive Tract Cancers.

Canned fish is a widely consumed and affordable food whose effect on cancer risk has been little investigated. We studied its effect on risk of upper digestive tract cancers using data from a network of hospital-based case-control studies from Northern Italy providing information about canned fish consumption as a separate item and including a total of 946 patients with oral cavity and pharynx cancer, 304 patients with esophageal cancer, 230 patients with gastric cancer and 3273 controls. Twenty-three percent of patients with cancer of the oral cavity or pharynx and 26% of those with cancer of the stomach consumed ≥1 serving per week of canned fish, compared to 40% and 49% of the respective control group. Among cases of esophageal cancer and controls 22% consumed ≥1 serving per week of canned fish. Odds ratios for ≥1 vs <1 portion per week were 0.79 (95% Confidence Interval, CI: 0.64-0.97) for cancer of the oral cavity and pharynx, and 0.59 (95% CI: 0.41-0.86) for stomach cancer, whereas there was no inverse association with esophageal cancer. These findings suggest a favorable role of canned fish for selected upper digestive tract cancers.

High Filamin a Expression in Adrenocortical Carcinomas Is Associated with a Favourable Tumour Behaviour: A European Multicentric Study.

The insulin-like growth factor 2 (IGF2) promotes cell growth by overactivating the IGF system in an autocrine loop in adrenocortical carcinomas (ACCs). The cytoskeleton protein filamin A (FLNA) acts as a repressor of IGF2 mitogenic signalling in ACC cells. The aims of this study were to test FLNA expression by immunohistochemistry in 119 ACCs and 26 adrenocortical adenomas (ACAs) and to evaluate its relationship with clinicopathological features and outcome in ACCs. We found that 71.4% of ACCs did not express FLNA, whereas FLNA absence was a rare event in ACAs (15.4%, p < 0.001 vs. ACCs). In addition, the expression of FLNA was associated with a less aggressive tumour behaviour in ACCs. Indeed, the subgroup of ACCs with high FLNA showed a lower ENSAT stage, Weiss score, and S-GRAS score compared to ACCs with low FLNA expression (p < 0.05). Moreover, patients with high FLNA had a longer overall survival than those with low FLNA (p < 0.05). In conclusion, our data suggest that FLNA may represent a "protective" factor in ACCs, and the integration of FLNA immunohistochemical expression in ACC tissues along with other clinical and molecular markers could be helpful to improve diagnostic accuracy and prognosis prediction in ACCs.

Diabetes risk reduction diet and the risk of pancreatic cancer.

PURPOSE: To evaluate the role of a diabetes risk reduction diet (DRRD) on pancreatic cancer risk. METHODS: We used data from a hospital-based case-control study conducted in Italy between 1991 and 2008; the study included 326 incident pancreatic cancer cases and 652 controls matched by age, gender and study center. Subjects' usual diet was collected through a valid and reproducible food frequency questionnaire. A DRRD score was derived from 8 dietary components: cereal fiber, total fruit, coffee, polyunsaturated to saturated fats ratio and nuts (higher score for higher intake), and dietary glycemic index, red/processed meat and sugar-sweetened beverages/fruit juices (higher score for lower intake). The score ranged 8-37, with higher values indicating greater DRRD adherence. Odds ratios (ORs) of pancreatic cancer according to the DRRD score were estimated using multiple conditional logistic regression models. RESULTS: After allowance for confounding factors, the DRRD score was inversely related to pancreatic cancer risk, with ORs of 0.55 (95% confidence interval, CI 0.38-0.80) for the highest versus the lowest score tertile (p for trend across tertiles = 0.002) and 0.84 (95% CI 0.75-0.95) for a 3-point score increment. The exclusion of diabetic subjects and additional adjustment for vegetable intake did not change the results. Inverse associations were observed in subgroups defined by age, gender, education, body mass index, smoking and total energy intake. CONCLUSION: Study findings suggest a protective role of high adherence to a DRRD on pancreatic cancer risk.

Dietary Intake of Breastfeeding Mothers in Developed Countries: A Systematic Review and Results of the MEDIDIET Study.

BACKGROUND: Lactation is a demanding period for women, and a good nutrition is crucial for optimal health of mothers and infants. OBJECTIVES: To provide new data and summarize the overall evidence on maternal nutrient intakes during lactation in developed countries, we present a systematic review (SR) of the literature and concurrently original results of the Italian MEDIDIET study. We compared nutrient intakes with dietary reference values (DRVs) proposed by the European Food Safety Authority. METHODS: Studies were identified searching PubMed/Embase databases up to February 2020. Observational studies reporting at least energy and macronutrient intakes of healthy breastfeeding mothers who followed non-restricted and non-specific diets were included. Studies on populations with severe nutritional deficiencies were excluded. The MEDIDIET study enrolled 300 healthy breastfeeding mothers at 6 ± 1 wk postpartum. Usual diet was concomitantly evaluated through a validated and reproducible FFQ. Nutrient intakes were estimated using a food composition database. RESULTS: Twenty-eight articles regarding 32 distinct study populations were included. Maternal nutrient intakes were generally in agreement across studies included in the SR and conforming to DRVs. Within micronutrients, vitamin D intake was below the recommendation. In the MEDIDIET study, mean intakes of energy (1950 ± 445 kcal/d), carbohydrates (270 ± 20.1 g/d), proteins (87.8 ± 20.1 g/d), and fats (65.6 ± 18.9 g/d) were similar to those observed in the SR. Moreover, observed intakes seemed to reflect the typical Mediterranean diet, with low intakes of carbohydrates, SFAs, and PUFAs and high intakes of MUFAs and vitamins. Conversely, protein intake was mainly derived from animal sources. CONCLUSIONS: This SR showed that nutrient intakes of breastfeeding mothers in developed countries are generally in line with DRVs despite different dietary patterns worldwide. Some nutritional deficiencies emerged, highlighting the need for additional nutritional advice. Mothers participating in the MEDIDIET study showed a nutritional profile in agreement with the Mediterranean diet.

Lessons learned from the INHANCE consortium: An overview of recent results on head and neck cancer.

OBJECTIVE: To summarize the latest evidence on head and neck cancer epidemiology from the International Head and Neck Cancer Epidemiology (INHANCE) consortium. SUBJECTS AND METHODS: INHANCE was established in 2004 to elucidate the etiology of head and neck cancer through pooled analyses of individual-level data on a large scale. We summarize results from recent INHANCE-based publications updating our 2015 overview. RESULTS: Seventeen papers were published between 2015 and May 2020. These studies further define the nature of risks associated with tobacco and alcohol, and occupational exposures on head and neck cancer. The beneficial effects on incidence of head and neck cancer were identified for good oral health, endogenous and exogenous hormonal factors, and selected aspects of diet related to fruit and vegetables. INHANCE has begun to develop risk prediction models and to pool follow-up data on their studies, finding that ~30% of cases had cancer recurrence and 9% second primary cancers, with overall- and disease-specific 5-year-survival of 51% and 57%, respectively. CONCLUSIONS: The number and importance of INHANCE scientific findings provides further evidence of the advantages of large-scale internationally collaborative projects and will support the development of prevention strategies.

Dietary patterns and oral and pharyngeal cancer using latent class analysis.

The methods traditionally used to identify a posteriori dietary patterns are principal components, factor and cluster analysis. The aim of our study is to assess the relationship between dietary patterns derived with latent class analysis (LCA) and oral/pharyngeal cancer risk (OPC), highlighting the strengths of this method compared to traditional ones. We analyzed data from an Italian multicentric case-control study on OPC including 946 cases and 2,492 hospital controls. Dietary patterns were derived using LCA on 25 food groups. A multiple logistic regression model was used to derive odds ratios (ORs) and corresponding 95% confidence intervals (CIs) for OPC according to the dietary patterns identified. We identified four dietary patterns. The first one was characterized by a high intake of leafy and fruiting vegetable and fruits (Prudent pattern), the second one showed a high intake of red meat and low intake of selected fruits and vegetables (Western pattern). The last two patterns showed a combination-type of diet. We labeled "Lower consumers-combination pattern" the cluster that showed a low intake of the majority of foods, and "Higher consumers-combination pattern" the one characterized by a high intake of various foods. Compared to the "Prudent pattern", the "Western" and the "Lower consumers-combination" ones were positively related to the risk of OPC (OR = 2.56, 95% CI: 1.90-3.45 and OR = 2.23, 95% CI: 1.64-3.02). No difference in risk emerged for the "Higher consumers-combination pattern" (OR = 1.28, 95% CI: 0.92-1.77).

A 2-year point-prevalence surveillance of healthcare-associated infections and antimicrobial use in Ferrara University Hospital, Italy.

BACKGROUND: Healthcare-Associated Infections (HAIs) represent one of the leading issues to patient safety as well as a significant economic burden. Similarly, Antimicrobial Use (AMU) and Resistance (AMR) represent a growing threat to global public health and the sustainability of healthcare services. METHODS: A Point Prevalence Survey (PPS) following the 2016 ECDC protocol for HAI prevalence and AMU was conducted at Ferrara University Hospital (FUH). Data were collected by a team of trained independent surveyors in 2016 and 2018. Risk factors independently associated with HAI were assessed by a multivariate logistic regression model. RESULTS: Of the 1102 patients surveyed, 115 (10.4%) had an active HAI and 487 (44.2%) were on at least 1 systemic antimicrobial agent. Factors independently associated with increased HAI risk were a "Rapidly Fatal" McCabe score (expected fatal outcome within 1 year), presence of medical devices (PVC, CVC, indwelling urinary catheter or mechanically assisted ventilation) and a length of hospital stay of at least 1 week. The most frequent types of HAI were pneumonia, bloodstream infections, and urinary tract infections. Antimicrobial resistance to third-generation cephalosporins was observed in about 60% of Enterobacteriaceae. CONCLUSIONS: The survey reports a high prevalence of HAI and AMU in FUH. Repeated PPSs are useful to control HAIs and AMU in large acute-care hospitals, highlighting the main problematic factors and allowing planning for improvement actions.

Health effects of living near an incinerator: A systematic review of epidemiological studies, with focus on last generation plants.

Huge reductions in incinerators' emissions occurred over time, and results of older studies cannot be directly generalized to modern plants. We conducted a systematic review of the epidemiologic evidence of the health effects of incinerators, classifying plants in three generations, according to emission limits. A systematic search identified 63 epidemiologic studies, published in English, investigating health effects of incinerators on humans. We focused on cancer, cardio-cerebrovascular diseases (CVD) and respiratory diseases, pregnancy outcomes and congenital anomalies. Only six studies in the general population were on third generation incinerators providing data on pregnancy outcomes and congenital anomalies. Given the heterogeneity of methods, the abundance of ecological/semi-ecological studies and the lack of reliable quantitative measures of exposure in several studies we did not perform any meta-analysis. No excesses emerged concerning all cancers and lung cancer. An excess of non-Hodgkin lymphoma was reported in some earlier studies, but not for second generation plants. Possible excesses of soft tissue sarcomas were confined to earlier incinerators and the areas closer to the plants. No clear association emerged for CVD and diseases of the respiratory system. Several different pregnancy outcomes were considered, and no consistent association emerged, in spite of a few positive results. Studies were negative for congenital anomalies as a whole. Sporadic excesses were reported in a few studies for specific types of anomalies, but no consistent pattern emerged. Evaluation of the evidence was hindered by heterogeneity in reporting and classification of outcomes across studies. Direct evidence from third generation plants is scarce. Methodological issues in study design (mainly related to exposure assessment, confounding and ecological design) and analysis make interpretation of results complex. In spite of this, the overall evidence suggests that, if there were any excesses at all for older incinerators, they were modest at most. Additional monitoring of third generation plants needs to overcome methodological weaknesses.

Diagnostic anticipation to reduce emergency department length of stay: a retrospective cohort study in Ferrara University hospital, Italy.

BACKGROUND: Emergency Department (ED) crowding reduces staff satisfaction and healthcare quality and safety, which in turn increase costs. Despite a number of proposed solutions, ED length of stay (LOS) - a main cause of overcrowding - remains a major issue worldwide. This retrospective cohort study was aimed at evaluating the effectiveness on ED LOS of a procedure called "Diagnostic Anticipation" (DA), which consisted in anticipating the ordering of blood tests by nurses, at triage, following a diagnostic algorithm approved by physicians. METHODS: In the second half of 2019, the ED of the University Hospital of Ferrara, Italy, adopted the DA protocol on alternate weeks for all patients with chest pain, abdominal pain, and non-traumatic bleeding. A retrospective cohort study on DA impact was conducted. Using ED electronic data, LOS independent predictors (age, sex, NEDOCS and Priority Color Code, imaging tests, specialistic consultations, hospital admission) were evaluated through multiple regression. RESULTS: During the weeks when DA was adopted, as compared to control weeks, the mean LOS was shorter by 18.2 min for chest pain, but longer by 15.7 min for abdominal pain, and 33.3 for non-traumatic bleeding. At multivariate analysis, adjusting for age, gender, triage priority, specialist consultations, imaging test, hospitalization and ED crowding, the difference in visit time was significant for chest pain only (p < 0.001). CONCLUSIONS: The impact of DA varied by patients' condition, being significant for chest pain only. Further research is needed before the implementation, estimating the potential proportion of inappropriate blood tests and ED crowding status.

Citrus fruit intake and gastric cancer: The stomach cancer pooling (StoP) project consortium.

Diets rich in vegetables and fruit have been associated with reduced risk of gastric cancer, and there is suggestive evidence that citrus fruits have a protective role. Our study aimed at evaluating and quantifying the association between citrus fruit intake and gastric cancer risk. We conducted a one-stage pooled analysis including 6,340 cases and 14,490 controls from 15 case-control studies from the stomach cancer pooling (StoP) project consortium. Odds ratios (ORs) and the corresponding 95% confidence intervals (CIs) of gastric cancer across study-specific tertiles of citrus fruit intake (grams/week) were estimated by generalized linear mixed effect models, with logistic link function and random intercept for each study. The models were adjusted for sex, age, and the main recognized risk factors for gastric cancer. Compared to the first third of the distribution, the adjusted pooled OR (95% CI) for the highest third was 0.80 (0.73-0.87). The favourable effect of citrus fruits increased progressively until three servings/week and leveled off thereafter. The magnitude of the association was similar between cancer sub-sites and histotypes. The analysis by geographic area showed no association in studies from the Americas. Our data confirm an inverse association between citrus fruits and gastric cancer and provide precise estimates of the magnitude of the association. However, the null association found in studies from America and in some previous cohort studies prevent to draw definite conclusions on a protective effect of citrus fruit consumption.

Mediterranean diet and outcomes of assisted reproduction: an Italian cohort study.

BACKGROUND: Detrimental lifestyle habits have been indicated as potential causes of reduced fertility. Recently studies have suggested an association between healthy diets and increased live birth rates after assisted reproduction techniques. However, the issue remains under debate, and evidence is still accumulating. OBJECTIVE: The objective of the study was to study the relationship between a Mediterranean diet and outcomes of assisted reproduction techniques in subfertile couples in an Italian population. STUDY DESIGN: This was a prospective cohort study, conducted in an Italian fertility clinic. Couples undergoing in vitro fertilization were interviewed on the day of oocyte retrieval to obtain information on personal and health history, lifestyle habits, and diet. Adherence to a Mediterranean diet was evaluated using a Mediterranean diet score. Relative risks and 95% confidence intervals for embryo transfer, clinical pregnancy, and live birth were calculated. Potential confounders were included in the equation model. RESULTS: Among 474 women (mean age, 36.6 years, range, 27-45), 414 (87.3%) performed embryo transfer, 150 (31.6%) had clinical pregnancies, and 117 (24.7%) had live births. In a model including the potential confounders (age, leisure physical activity, body mass index, smoking, daily calorie intake, and previous failed in vitro fertilization cycles), findings showed that the Mediterranean diet score was not significantly associated with in vitro fertilization outcomes. Adjusted analyses were performed in strata of age, previous assisted reproduction technique cycles, and reasons for infertility, with consistent findings. The only exception was observed in women >35 years old with an intermediate Mediterranean diet score, who showed a lower risk of not achieving clinical pregnancy (adjusted relative risk, 0.84, 95% confidence interval, 0.71-1.00, P = .049). CONCLUSION: No clear association was observed between adherence to a Mediterranean diet and successful in vitro fertilization.

Do health care professionals' perceptions help to measure the degree of overcrowding in the emergency department? A pilot study in an Italian University hospital.

BACKGROUND: Overcrowding in emergency departments (EDs) is internationally recognized as one of the greatest challenges to healthcare provision. Numerous studies have highlighted the ill-effects of overcrowding, including increased length of stay, mortality and cost per admission. This study measures overcrowding in EDs through health care professionals' perceptions of it, comparing the results with the NEDOCS score, an objectively validated measurement tool and describing meaningful tools and strategies used to manage ED overcrowding. METHODS: This single-centre prospective, observational, pilot study was conducted from February 19th to March 7th, 2018 at the ED in the University Hospital of Ferrara, Italy to measure the agreement of the NEDOCS, comparing objective scores with healthcare professionals' perception of overcrowding, using the kappa statistic assessing linear weights according to Cohen's method. The tools and strategies used to manage ED overcrowding are described. RESULTS: Seventy-two healthcare professionals (66.1% of 109 eligible subjects) were included in the analyses. The study obtained a total of 262 surveys from 23 ED physicians (31.9%), 31 nurses (43.1%) and 18 nursing assistants (25.0%) and a total of 262 NEDOCS scores. The agreement between the NEDOCS and the subjective scales was poor (k = 0.381, 95% CI 0.313-0.450). CONCLUSIONS: The subjective health care professionals' perceptions did not provide an adequate real-time measure of the current demands and capacity of the ED. A more objective measure is needed to make quality decisions about health care professional needs and the ability to manage patients to ensure the provision of proper care.

Validation of the OPportunity for Treatment In ONcology (OPTION) questionnaire measuring continuity of care.

Increasing efforts are ongoing to deliver effective cancer care through integrated networks of services. Measuring patients' experience of care is essential to identify problematic areas that require organisational adjustments. The aim of the present study was to examine the validity of OPTION questionnaire, designed to measure patient's perceived continuity of care across different phases of their care pathway. The study was carried at the Institute for Cancer Treatment and Research, Meldola and the oncology departments of the Local Health Authority of Romagna, Italy. Principal component analysis (PCA) was performed to identify factors underlying patients' perception of continuity of care. Factor scores were compared between patients with or without a care coordinator using Mann-Whitney test. The study sample consisted of 214 patients with breast or colorectal cancer, with a mean age of 62.3 years. Most patients identified the oncologist as their care coordinator. Five factors were extracted using PCA: (1) "trustful relationship with health care staff," (2) "information on care pathway," (3) "information on changes related to the illness," (4) "feelings of abandonment" and (5) "collaboration among health care professionals." The scores of factors 2 and 3 were significantly higher among those with a care coordinator. The OPTION questionnaire is a reliable instrument that can help clinicians and administrative stakeholder target efforts and resources in the pursuit of quality of care.

Adherence to the Mediterranean diet and nasopharyngeal cancer risk in Italy.

PURPOSE: Few studies investigated the role of diet on nasopharyngeal cancer (NPC) risk in non-endemic areas. The aim of this study was to assess the association between adherence to the traditional Mediterranean diet and NPC risk in a southern European low-risk population. METHODS: We conducted a hospital-based case-control study in Italy, including 198 histologically confirmed NPC cases and 594 matched controls. Dietary habits were collected by means of a validated food-frequency questionnaire, including 83 foods, food groups, or beverages. Adherence to the traditional Mediterranean diet was assessed through a Mediterranean Diet Score (MDS), based on nine dietary components characterizing this dietary profile, i.e., high intake of vegetables, fruits and nuts, cereals, legumes, and fish; low intake of dairy products and meat; high monounsaturated to saturated fatty acid ratio; and moderate alcohol intake. We estimated odds ratios (ORs) of NPC, and the corresponding 95% confidence intervals (CIs), for increasing MDS (i.e., increasing adherence) using multiple logistic regression models, adjusted for major confounding factors. RESULTS: As compared to MDS ≤ 4, the ORs of NPC were 0.83 (95% CI: 0.54-1.25) for MDS of 5 and 0.66 (95% CI: 0.44-0.99) for MDS ≥ 6, with a significant trend of decreasing risk (p 0.043). The corresponding population attributable fraction was 22%, indicating that 22% of NPC cases in this population would be avoided by shifting all subjects to a score ≥6. CONCLUSIONS: Our study supports a favorable role of the Mediterranean diet on NPC risk.

[Patient engagement in health care. New perspectives in oncology]. / La partecipazione della persona al percorso di cura.Nuove prospettive in oncologia.

During the last decade, an increasing number of studies has been focused on patient engagement programs through which patients can be effective and informed managers of their health and health care. Based on our recent review, studies examining the nature of patient participation in service planning have found that most activities are limited to various forms of consultation, rather than the interactive partnerships advocated for treatment decision-making. Despite this clear evidence, many people want to play an active role in their own healthcare. They want to know how to protect and improve their health when they are well; and when they are ill, they want information about treatment options and likely outcomes. Consistent with these considerations, this paper intends to underline the importance to engage patients, to describe some different interventions to make patient effective informed; and, finally, to show some pilot projects from around the world, with a special focus on cancer care service of Ontario.

Mediterranean diet and hepatocellular carcinoma.

BACKGROUND & AIMS: Hepatocellular carcinoma (HCC) has a very poor prognosis and any effort to identify additional risk factors, besides those already established, would be important for the prevention of the disease. Data on the role of diet on HCC risk are still controversial. METHODS: We have evaluated the association of adherence to the Mediterranean diet with HCC risk, as well as the interaction of this dietary pattern with chronic hepatitis infection, by combining two case-control studies undertaken in Italy and Greece, including overall 518 cases of HCC and 772 controls. Adherence to the traditional Mediterranean diet was assessed through the Mediterranean diet score (MDS), which ranges between 0 (lowest adherence) and 9 (highest adherence). Odds ratios (OR) for HCC were obtained through multiple logistic regression models, controlling for potentially confounding factors, including chronic infection with hepatitis B/C viruses. RESULTS: Compared to MDS of 0-3, the ORs for HCC were 0.66 (95% confidence interval (CI), 0.41-1.04) for MDS equal to 4 and 0.51 (95% CI, 0.34-0.75) for MDS ⩾ 5, with a significant trend (p<0.001). The detrimental effect of poor adherence to Mediterranean diet on HCC risk was disproportionally high among those chronically infected with hepatitis B and/or C viruses, with a suggestion of super-additive interaction, albeit statistically non-significant. CONCLUSIONS: Closer adherence to the Mediterranean diet appears to be protective against HCC. Our results also point to potential benefits from adhering to a Mediterranean dietary pattern for patients chronically infected with hepatitis viruses.

Nutrient-based dietary patterns and prostate cancer risk: a case-control study from Italy.

PURPOSE: The role of various foods and nutrients, and their combinations, on prostate cancer risk remains largely undefined. We addressed therefore the issue of complex dietary patterns. METHODS: We analyzed data from an Italian case-control study, including 1,294 men with prostate cancer and 1,451 hospital controls. We carried out an exploratory principal component factor analysis on 28 selected nutrients in order to identify dietary patterns. We estimated odds ratios (ORs) and corresponding confidence intervals (CIs) using logistic regression models on quintiles of factor scores, adjusting for major confounding variables. RESULTS: We identified five dietary patterns, labeled "Animal Products," "Vitamins and Fiber," "Starch-rich," "Vegetable Unsaturated Fatty Acids (VUFA)," and "Animal Unsaturated Fatty Acids (AUFA)." We found positive associations between prostate cancer and "Animal Products" (OR for the highest vs. the lowest score quintile: 1.51, 95 % CI 1.16-1.96), "Starch-rich" (OR 1.50, 95 % CI 1.16 1.93), and "AUFA" (OR 1.32, 95 % CI 1.02-1.70) patterns. No significant associations emerged with "Vitamins and Fiber" (OR 0.93) and "VUFA" (OR 1.16) patterns. CONCLUSIONS: Our findings suggest that a diet rich in animal products, including several types of meat and dairy products, as well as of (refined) cereals and sugars has an unfavorable role on prostate cancer.

Coffee and caffeine intake and risk of endometriosis: a meta-analysis.

PURPOSE: The potential association between endometriosis and coffee/caffeine consumption has been analysed in several epidemiological studies. In order to establish whether caffeine influences the risk of endometriosis, we provide to summarize the evidence from published studies on this issue. METHODS: We performed a meta-analysis of epidemiological studies published up to January 2013. We computed summary relative risks (RR) of endometriosis for any, high and low versus no coffee/caffeine consumption. RESULTS: We identified a total eight studies, six case-control and two cohort studies, including a total of 1,407 women with endometriosis. The summary RR for any versus non-consumption were 1.26 [95% confidence interval (CI) 0.95-1.66] for caffeine and 1.13 (95% CI 0.46-2.76) for coffee consumption; the overall estimate was 1.18 (95% CI 0.92-1.49). The summary RR were 1.09 (95% CI 0.84-1.42) and 1.09 (95% CI 0.89-1.33) for high and low caffeine consumption as compared to no consumption, respectively. CONCLUSION: The present meta-analysis provided no evidence for an association between coffee/caffeine consumption and the risk of endometriosis. Coffee/caffeine consumption, as currently used in diet, does not carry a health risk.

Source Control and Antibiotics in Intra-Abdominal Infections.

Intra-abdominal infections (IAIs) account for a major cause of morbidity and mortality, representing the second most common sepsis-related death with a hospital mortality of 23-38%. Prompt identification of sepsis source, appropriate resuscitation, and early treatment with the shortest delay possible are the cornerstones of management of IAIs and are associated with a more favorable clinical outcome. The aim of source control is to reduce microbial load by removing the infection source and it is achievable by using a wide range of procedures, such as definitive surgical removal of anatomic infectious foci, percutaneous drainage and toilette of infected collections, decompression, and debridement of infected and necrotic tissue or device removal, providing for the restoration of anatomy and function. Damage control surgery may be an option in selected septic patients. Intra-abdominal infections can be classified as uncomplicated or complicated causing localized or diffuse peritonitis. Early clinical evaluation is mandatory in order to optimize diagnostic testing and establish a therapeutic plan. Prognostic scores could serve as helpful tools in medical settings for evaluating both the seriousness and future outlook of a condition. The patient's conditions and the potential progression of the disease determine when to initiate source control. Patients can be classified into three groups based on disease severity, the origin of infection, and the patient's overall physical health, as well as any existing comorbidities. In recent decades, antibiotic resistance has become a global health threat caused by inappropriate antibiotic regimens, inadequate control measures, and infection prevention. The sepsis prevention and infection control protocols combined with optimizing antibiotic administration are crucial to improve outcome and should be encouraged in surgical departments. Antibiotic and antifungal regimens in patients with IAIs should be based on the resistance epidemiology, clinical conditions, and risk for multidrug resistance (MDR) and Candida spp. infections. Several challenges still exist regarding the effectiveness, timing, and patient stratification, as well as the procedures for source control. Antibiotic choice, optimal dosing, and duration of therapy are essential to achieve the best treatment. Promoting standard of care in the management of IAIs improves clinical outcomes worldwide. Further trials and stronger evidence are required to achieve optimal management with the least morbidity in the clinical care of critically ill patients with intra-abdominal sepsis.

Coffee reduces risk for hepatocellular carcinoma: an updated meta-analysis.

BACKGROUND & AIMS: Coffee consumption has been suggested to reduce the risk for hepatocellular carcinoma (HCC). We performed a meta-analysis of epidemiological studies to provide updated information on how coffee drinking affects HCC risk. METHODS: We performed a PubMed/MEDLINE search of the original articles published in English from 1966 through September 2012, on case-control or cohort studies that associated coffee consumption with liver cancer or HCC. We calculated the summary relative risk (RR) for any, low, and high consumption of coffee vs no consumption. The cut-off point for low vs high consumption was set to 3 cups per day in 9 studies and 1 cup per day in 5 studies. RESULTS: The summary RR for any coffee consumption vs no consumption was 0.60 from 16 studies, comprising a total of 3153 HCC cases (95% confidence interval [CI], 0.50-0.71); the RRs were 0.56 from 8 case-control studies (95% CI, 0.42-0.75) and 0.64 from 8 cohort studies (95% CI, 0.52-0.78). Compared with no coffee consumption, the summary RR was 0.72 (95% CI, 0.61-0.84) for low consumption and 0.44 (95% CI, 0.39-0.50) for high consumption. The summary RR was 0.80 (95% CI, 0.77-0.84) for an increment of 1 cup of coffee per day. The inverse relationship between coffee and HCC risk was consistent regardless of the subjects' sex, alcohol drinking, or history of hepatitis or liver disease. CONCLUSIONS: From this meta-analysis, the risk of HCC is reduced by 40% for any coffee consumption vs no consumption. The inverse association might partly or largely exist because patients with liver and digestive diseases reduce their coffee intake. However, coffee has been shown to affect liver enzymes and development of cirrhosis, and therefore could protect against liver carcinogenesis.
