Q fever (caused by Coxiella burnetii) is thought to have an almost world-wide distribution, but few countries have conducted national serosurveys. We measured Q fever seroprevalence using residual sera from diagnostic laboratories across Australia. Individuals aged 1–79 years in 2012–2013 were sampled to be proportional to the population distribution by region, distance from metropolitan areas and gender. A 1/50 serum dilution was tested for the Phase II IgG antibody against C. burnetii by indirect immunofluorescence. We calculated crude seroprevalence estimates by age group and gender, as well as age standardised national and metropolitan/non-metropolitan seroprevalence estimates. Of 2785 sera, 99 tested positive. Age standardised seroprevalence was 5.6% (95% confidence interval (CI 4.5%–6.8%), and similar in metropolitan (5.5%; 95% CI 4.1%–6.9%) and non-metropolitan regions (6.0%; 95%CI 4.0%–8.0%). More males were seropositive (6.9%; 95% CI 5.2%–8.6%) than females (4.2%; 95% CI 2.9%–5.5%) with peak seroprevalence at 50–59 years (9.2%; 95% CI 5.2%–13.3%). Q fever seroprevalence for Australia was higher than expected (especially in metropolitan regions) and higher than estimates from the Netherlands (2.4%; pre-outbreak) and US (3.1%), but lower than for Northern Ireland (12.8%). Robust country-specific seroprevalence estimates, with detailed exposure data, are required to better understand who is at risk and the need for preventive measures.

Mumps is an acute and common childhood disease caused by paramyxovirus. It has been reported that the occurrence of mumps is influenced by seasonality. However, the role of meteorological variables in the incidence of mumps remains unclear. The purpose of this study was to explore the relationship between meteorological factors and the incidence of mumps infection. Poisson regression analysis was used to study the relationship between weather variability and the incidence of mumps in Taiwan. Between 2012 and 2018, 5459 cases of mumps cases were reported to the Centers for Disease Control, Taiwan (Taiwan CDC). The occurrence of mumps virus infections revealed significant seasonality in the spring and summer seasons in Taiwan. The incidence of mumps virus infections began to increase at temperatures of 15°C and started to decline if the temperature was higher than 29°C ( r 2 = 0.387, P = .008). Similarly, the number of mumps cases began to increase at a relative humidity of 65% to 69% ( r 2 = 0.838, P < .029). The number of mumps cases was positively associated with temperature and relative humidity during the period preceding the infection. This study showed that the occurrence of mumps is significantly associated with increasing temperature and relative humidity in Taiwan. Therefore, these factors could be regarded as early warning signals and indicate the need to strengthen the intervention and prevention of mumps.

A dietary pattern transition is a risk factor for the double burden of malnutrition (DBM), but related information is limited. This study aimed to identify sex differences in dietary patterns of adults in a low–middle income country and to examine their association with DBM. A total of 8957 adults (4465 men and 4492 non-pregnant and non-lactating women) who participated in the 2013 Philippine National Nutrition Survey were included in the analysis. Logistic regression models were formulated to investigate the relationship between dietary patterns and DBM. The factor analysis derived seven dietary patterns for males and six patterns for females. Results showed that approximately 30% of Filipino adults suffered from DBM. The rice pattern was associated with lower odds of DBM for males only. The meat and sugar pattern in males and the protein-rich foods, cereal, and sugar pattern in females decreased DBM likelihood. An inverse relationship was observed for the vegetables and corn patterns, wherein females had an increased risk for DBM. Our findings suggest that rice-based and meat-containing patterns could play protective roles in DBM development among adults in the Philippines. Understanding sex-specific dietary patterns can be utilized to guide public health nutrition interventions in the prevention of malnutrition in all its forms.

Aim The effects of diabetes mellitus (DM) on the outcomes of colorectal cancer (CRC) are controversial. This retrospective study evaluated the effects of DM on American Joint Committee on Cancer (AJCC, 7th) Stages II and III CRC patients who received curative surgery. Methods We reviewed the records of CRC patients who were treated from January 2008 to December 2014 and identified the presence of DM and hypertension prior to CRC diagnosis. Cox proportional hazards analyses were used for prognostic factor determination, and survival was analyzed using the Kaplan–Meier method with the log‐rank test. Results Total of 1066 consecutive eligible patients with stage II/III CRC were enrolled. There were 326 (30.6%) patients diagnosed with DM, and 311 (29.2%) CRC patients had recurrence. Patients with DM did not have a higher recurrence risk (p = 0.183) but had higher mortality (adjusted hazard ratio [aHR] = 1.381; 95% conference interval [CI], 1.069–1.782). In addition, HbA1c (≥7 vs. <7) was not associated with recurrence (p = 0.365). Patients with DM had more hypertension than patients without DM (69.1% vs. 37.6%, p < 0.001). A lower recurrence risk was noted in patients with hypertension (p = 0.002), but the overall survival (OS) did not reach statistical significance (aHR = 0.910; 95% CI, 0.707–1.169). Conclusion In our study, DM was a poor prognostic factor for survival in curative CRC patients. More studies are required to elucidate the effects that DM and other metabolic disorders, such as hypertension, have on the prognosis of patients with CRC.

ObjectiveTo compare quality, quantity, and trends of food supply from 1984 to 2009 and degree of food westernization in Taiwan with Asian countries and world continents by using food balance data(FBS).MethodsWe compiled data from FBS of Taiwan and FAO, including five continents and three most populated countries each in Eastern, Southern, and South Eastern Asia over the period 1984‐2009. Quantity of food supply per capita was referenced to Taiwan food guides. The population‐weighted means of food supply from Europe, North America, South America, and Australia & New Zealand Continents in terms of energy and nutrient distributions, animal/plant sources, and sugar/alcohol contribution were used asindicators of westernization.FindingsTaiwan's food supply, although currently provides sufficient food per capita, showed decreasing trends through recent years. The cereals/roots supply and rice to wheat ratio kept as the lowest, while the meat and oil supplies per capita were the highest among the 10 studied Asian countries. Judging by the indices of food energy from animal food (kcal, %), total food protein(g), protein to total energy(%), total food fat(g), fat to total energy(%), protein/fat from animal sources(%),Taiwan had the most westernized food patterns.imageConclusionFood supply of Taiwan, although currently sufficient, indicated some security problems and high tendency of diet westernization.
