Giardia duodenalisis a major cause of infectious gastroenteritis worldwide, and it is diversified into eight genetic assemblages (A to H), which are distinguishable only by molecular typing. There is some evidence that the assemblages infecting humans (assemblages A and B) may have different transmission routes, but systematically acquired data, combining epidemiological and molecular findings, are required. We undertook a case-control study withGiardiagenotyping in North West England, to determine general and parasite assemblage-specific risk factors. For people without a history of foreign travel, swimming in swimming pools and changing diapers were the most important risk factors for the disease. People infected with assemblage B reported a greater number of symptoms and higher frequencies of vomiting, abdominal pain, swollen stomach, and loss of appetite, compared with people infected with assemblage A. More importantly, keeping a dog was associated only with assemblage A infections, suggesting the presence of a potential zoonotic reservoir for this assemblage. This is the first case-control study to combine epidemiological data withGiardiagenotyping, and it shows the importance of integrating these two levels of information for better understanding of the epidemiology of this pathogen.

We report the findings of the first case-control study conducted in both the Republic of Ireland and Northern Ireland to determine risk factors for sporadic Campylobacter infections. A total of 197 cases and 296 case-nominated controls matched for age, were included. Based on Population Attributable Fraction (PAF), the most important risk factors were consuming chicken [adjusted matched (am) OR 6.8; 95%CI 2.1-21.9], consuming lettuce (amOR 3.3; 95%CI 1.5-7.1) and eating in takeaways (amOR=3.1; 95%CI 1.4-6.6). Contact with sheep (amOR=11; 95%CI 1.6-78), peptic ulcer (amOR=19; 95%CI 3.8-93.7), hiatus hernia (amOR=20.3; 95%CI 2.3-183.3), lower bowel problems (amOR=4.5; 95%CI 1.2-16.8) were also independently associated with infection. Mains water supply showed protective effect (amOR=0.2; 95 CI 0.1-0.9). The findings highlight the continued need for consumer food safety education and further control measures throughout the food chain on the island of Ireland.

Purpose This study aims at determining the risk of physical inactivity and sedentary behaviors on overweight and obesity among primary school children aged 10–13 years in Tanzania. Design/methodology/approach A case-control study was conducted from January to March 2020 involving 69 overweight/obese children as cases and 138 normal weight children as controls. Cases were identified as having body mass index-for-age ≥ +1 standard deviation (SD) and controls as those having BMI-for-age range between −2 SD to <+1 SD. A validated questionnaire was used for data collection on daily physical activities and sedentary behavior types, frequency duration and activity score. An independent sample t-test was used to compare means of activity score between cases and controls. Binary logistic regression was used to predict risk factors for overweight/obesity. Findings Risk factors for overweight/obesity were listening to music and/or radio for >2 h/week (OR 2.7, 95% CI 1.2–6.1) and walking for exercise <2 h/week (OR 2.1, 95% confidence interval [CI] 1.1–4.1). On the other hand, rope skipping for >2 h/week (OR 0.14, 95% CI 0.03–0.7) was a protective factor against overweight/obesity. Controls had a significantly higher mean score of being active during lunch breaks compared to cases (p = 0.012). Cases had higher weight, height and percentage body fat than controls (p < 0.001). The home environment provided more avenues for physical activity than the school environment. Originality/value To the best of the authors’ knowledge, this is original research work and the first case-control study to predict physical activity and sedentary behaviors as risk factors for overweight and obesity in Tanzanian school children.

PURPOSE Esophageal cancer (EC) is one of the most common cancers in East Africa; however, risk factors that underly the high incidence in this region are not well understood. We aimed to investigate the association between exposure to specific alcohol subtypes and EC in Tanzania. METHODS We performed a secondary analysis of data from a hospital-based, case-control study conducted at Muhimbili National Hospital and Ocean Road Cancer Institute in Dar es Salaam, Tanzania. Cases of EC were identified between 2014 and 2016. Hospital controls were identified from patients with nonmalignant conditions and matched 1:1 for gender and age (± 10 years). Interviews were conducted using a survey with culturally relevant and context-specific questions on alcohol and smoking exposure. Conditional logistic regression analyses were applied to evaluate specific associations of potential exposures and EC. RESULTS A total of 473 EC cases and 473 controls were enrolled. Alcohol consumption was reported in 61% and 64% of cases and controls, respectively. Neither ‘current use of alcohol (any type)’, nor ‘ever use’ were associated with EC; however, local brew consumption was associated with increased EC risk (odds ratio [OR], 2.01; 95% CI, 1.53 to 2.66; P < .01). Increased risk was observed with consumption of gongo (OR, 2.91), komoni (OR, 2.41), wanzuki (OR, 2.40), kindi (OR, 3.13), and kangara (OR, 2.86). Smoking increased EC risk; however, it did not significantly modify the association between EC and alcohol subtypes. CONCLUSION This is the first case-control study to report a detailed analysis of alcohol exposures as a potential risk factor for EC in Tanzania. Although combined measures of alcohol use were not found to be associated with EC, several types of locally brewed alcohols emerged as risk factors. Additional research is needed to investigate these findings and examine the carcinogenic role of ingredients and/or contaminants, as well as any interactions with other putative risk factors in this region.

Squamous cell carcinoma of the larynx is a multifactorial disease. It is firmly linked to several environmental risk factors. In the meanwhile, a considerable amount of epidemiologic evidence has been built up to implicate chronic consumption of alcohol and tobacco, occupation, diet, and social status in the etiology of the laryngeal cancer. Herein is a report from the first case-control study on the role of these risk factors conducted in a German population of patients with laryngeal cancer.

ABSTRACTThe objective of this study was to determine risk factors for the development of resistance to β-lactams/β-lactamase inhibitors (βL/βLIs) and ertapenem amongBacteroidesspecies bacteremia. We conducted a retrospective case-control study of 101 adult patients withBacteroidesspecies bacteremia at a 1,051-bed tertiary care medical center. The duration of exposure to βL/βLIs (odds ratio [OR], 1.25; 95% confidence interval [CI], 1.08 to 2.31) was the only independent risk factor for resistance.

In 1995, Salmonella Enteritidis (SE) cases in the state of Utah increased fivefold. Isolates were identified as phage type 4 (PT4). Risk factors and sources of infection were investigated in two case-control studies, a traceback of implicated foods, and environmental testing. Forty-three patients with sporadic infections and 86 controls were included in a case-control study of risk factors for infection. A follow-up case-control study of 25 case and 19 control restaurants patronized by case and control patients examined risks associated with restaurant practices. In the first case-control study, restaurant dining was associated with illness (P = 0·002). In the follow-up case-control study, case restaurants were likelier to use > 2000 eggs per week (P < 0·02), to pool eggs (P < 0·05), and to use eggs from cooperative ‘A’ (P < 0·009). Eggs implicated in separately investigated SE PT4 outbreaks were traced to cooperative ‘A’, and SE PT4 was cultured from one of the cooperative's five local farms. We conclude that SE PT4 transmitted by infected eggs from a single farm caused a fivefold increase in human infections in Utah.
