Abstract
BACKGROUND HIV disparities continue to be a significant challenge affecting Black sexual minority men in the United States. Inadequate engagement and retention of patients in HIV care has been associated with poor health outcomes. Interventions to improve sustained commitment to HIV care are needed. Mobile health interventions can help facilitate access to and use of HIV health services, particularly among individuals at risk for disengaging with care. OBJECTIVE We designed the LetSync app wireframes for a mobile health intervention using a couple-centered design approach to improve HIV engagement and treatment among Black sexual minority men and their partners. The objective of this study was to gauge future app user interest and elicit feedback to improve the design, development, and usability of the LetSync app. METHODS We conducted in-depth interviews with 24 Black sexual minority men to assess the acceptability of the LetSync app wireframes between May 2020 and January 2021. Participants reviewed the LetSync app wireframes and provided feedback regarding perceived usefulness and interest in future app use and suggestions for improvement. RESULTS Participants indicated interest in the future LetSync app and noted that the wireframes' features were acceptable and usable. In our study, the future LetSync app was frequently referred to as a potential resource that could help facilitate users' engagement in HIV care through the following mechanisms: enable scheduling of appointments and timely reminders for clinic visits; help improve HIV medication adherence; encourage and motivate participants to ask questions to their health care provider and stay engaged in conversations during clinic visits; facilitate effective communication by assisting couples with planning, coordination, and management of daily routines; help participants understand their partner's health needs, including access to and use of health care services; and facilitate participants' ability to improve their relationship skills, partner support, and self-efficacy in managing conflict. In addition to near-universal interest in potential daily app use, study participants indicted that they would recommend the LetSync app to other family members, friends, and people in their social networks who are living with HIV. CONCLUSIONS Our findings revealed considerable interest in future app use for HIV care management, which could possibly increase the chance of the LetSync app being successfully adopted by Black sexual minority men in couples. Owing to its interactive and couple-centered approach, the LetSync app could help improve communication between Black sexual minority men and their partners and health providers. In addition, the LetSync app could provide an acceptable modality for these men to receive support in accessing HIV care services.

Abstract
BACKGROUND Eswatini is currently afflicted by an extremely high prevalence of HIV (27%) and malnutrition (both under-and over-nutrition). While rates of overweight/obesity in the general adult population have been documented, data on overweight/obesity and associated risk factors among women living with HIV (WLHIV) in Eswatini is limited. This study examines the prevalence of overweight/obesity and associated risk factors, with an emphasis on clarifying the association between household food insecurity and overweight/obesity for WLHIV in rural Eswatini. METHODS This cross-sectional study was conducted among WLHIV (n = 166) in rural communities of Eswatini. Data were collected using an interviewer-administered survey questionnaire between October and November, 2017. Body Mass Index (BMI) was calculated to determine overweight and obesity among study participants. Women with BMI values of 25 kg/m2 or greater were classified as being overweight/obese. Multivariable log-binomial regression models were used to examine associations between household food insecurity and overweight/obesity in our study. RESULTS Nearly a third (32.5%) of the women in our study were overweight and almost a quarter were obese (22.9%). We found significant associations between household food insecurity and overweight/obesity, with women who experienced household food insecurity the most being 0.38 times less likely to be overweight/obese compared to those who experienced household food insecurity the least (ARR: 0.38, 95% CI: 0.2-0.71). In our study sample, women who perceived themselves as being in poor health were less likely to be overweight/obese compared to those who perceived themselves as being in good health (ARR: 0.58, 95% CI: 0.39-0.86). We found significant associations between overweight/obesity and alcohol use, with the risk of overweight/obesity nearly 1.5 times higher among women who consumed alcohol compared to those who did not (ARR: 1.49, 95% CI: 1.07-2.05). CONCLUSIONS The high prevalence of overweight/obesity among food insecure women in poverty stricken communities may pose significant challenges for nutritional health and HIV management. With an increasing prevalence of overweight/obesity in food insecure households, there is a need to re-evaluate current strategies and develop multi-level targeted interventions that include prevention of excessive weight gain among women, particularly those living with HIV in rural Eswatini. HIV programs could include screening to identify individuals at risk for overweight/obesity in this population, and provide nutrition education for weight management for those individuals.

Abstract
Background Eswatini has the highest global prevalence of HIV despite decades of universal access to free antiretroviral therapy (ART). We conducted a mixed methods study to investigate barriers to ART adherence among women living with HIV (WLHIV) in rural communities of Eswatini. Qualitative findings were reported in our previous publication. This subsequent paper expands on our qualitative analysis to examine the magnitude to which identified barriers impacted ART adherence among WLHIV in the same communities. Methods We used an exploratory sequential design to collect data from WLHIV (n = 166) in rural Eswatini. Quantitative data were collected using interviewer-administered survey questionnaires between October and November 2017. ART adherence was measured using the CASE Adherence Index, with scores less than 10 indicating nonadherence. Log-binomial regression models were used to examine the extent to which critical barriers affected ART adherence among study participants. Results A majority of the women in our study (56%) were nonadherent to ART. Of the barriers identified in our prior qualitative analysis, only eight were found to be significantly associated with ART nonadherence in our quantitative analysis. These include, with adjusted risk ratios (ARR) and 95% confidence intervals (95% CI): household food insecurity (ARR: 3.16, 95% CI: 1.33–7.52), maltreatment by clinic staff (ARR: 2.67, 95% CI: 1.94–3.66), forgetfulness (ARR: 1.80, 95% CI: 1.41–2.31), stress (ARR: 1.47, 95% CI: 1.14–1.88), gossip (ARR: 1.57, 95% CI: 1.21–2.04), mode of transport (ARR: 0.59, 95% CI: 0.44–0.79), age (ARR: 0.98, 95% CI: 0.97–0.99), and lack of community support (ARR: 0.55, 95% CI: 0.35–0.85). Conclusions Among numerous barriers identified in our study, food insecurity was found to be a significant contributor toward ART nonadherence among women living with HIV in rural Eswatini. Future strategies aimed at improving ART adherence in Eswatini should include programs which provide food and nutrition support for people living with HIV, particularly rural women living in poverty.

Abstract
Background Despite access to free antiretroviral therapy (ART) for all people living with human immunodeficiency virus (HIV), noncompliance to treatment continues to be a significant challenge in Eswatini. Yet studies investigating barriers to ART adherence in Eswatini are scarce. Most notably, there is a lack of research regarding rural women in Eswatini, who are currently the country’s most vulnerable to HIV infection. Therefore, the objective of the study is to investigate individual, household, and community level barriers to ART adherence among rural women living with HIV. Methods We conducted a qualitative study to investigate individual, household, and community level barriers to ART adherence. We conducted focus group discussions with HIV-infected women (n = 4) from rural villages in Eswatini, and in-depth interviews with healthcare workers (n = 8) serving the area clinics. Open and axial coding techniques were used for data analysis and interpreted within a social ecological framework. Results Our findings revealed several individual level barriers including hunger, side effects of ART, personal stress, lack of disclosure of HIV status, alcohol use, and forgetting to take ART. Lack of food, unemployment and scarcity of financial resources were identified as critical barriers at the household level. Community and institutional barriers encompassed factors related to health delivery such as lack of privacy, travel time, transportation costs, excessive alcohol use by healthcare workers, maltreatment, public and self-stigma, gossip, and long waits at clinics. Conclusions Rural women living with HIV face multilevel barriers to ART adherence. Support programs aimed at increasing ART adherence among this vulnerable population need to develop targeted polices to alleviate challenges rural women face, beginning with expanding qualifications for food assistance programs.

Abstract
Background: Antonovsky's concept of sense of coherence (SOC) - as a global orientation reflecting an individual's feeling of confidence in both the predictability of their internal and external environment and their ability to cope with stressful and challenging situations in life - shows a negative association with symptoms of post-traumatic stress. However, single studies varying in study characteristics provide heterogeneous effect size estimations. Objective: The purpose of the current study is to investigate the relationship between SOC and post-traumatic stress disorder (PTSD) symptom severity for the first time on a meta-analytical level. Method: The random-effects meta-analysis is based on zero-order correlations (r) and consists of 47 independent samples out of 45 studies (N = 10,883). Results: After correcting for sampling error, the mean correlation between SOC and PTSD symptoms was M(r) = -.41 (excluding four outliers: -.39). However, this effect could not be generalized to all types of PTSD samples owing to substantial remaining heterogeneity. Subsequent moderator analyses investigating the influence of different SOC and PTSD measures, trauma type and duration, mean age and gender imbalances per sample did not reveal significant moderating effects. Conclusions: The meta-analysis reveals a substantial correlation between SOC and PTSD symptom severity: higher SOC levels are associated with lower symptom severity. Thus, future research should progress to the question of whether the relationship between SOC and post-traumatic stress is causal, and by which factors it is moderated.

Abstract
Zusammenfassung
Gegenstand und Ziel: Gewinn epidemiologischer Daten zur Fütterung von Hunden und Katzen in Deutschland.
Material und Methoden: 865 Hundeund 243 Katzenbesitzer wurden anhand standardisierter Fragebögen zu ihrem Tier (Alter, Geschlecht, Gewicht, Ernährungszustand, Gesundheit), dessen Fütterung inklusive Belohnungen und Zusätzen, den Gründen für eine Futterumstellung und zur eigenen Person (Alter, Geschlecht, Schulbildung, Beruf) befragt. Die Befragungen fanden in Tierarztpraxen, Hundeschulen, Tierheimen, Parkanlagen und via Internet statt. Zudem wurde der Body Condition Score (BCS) der Tiere durch ihre Besitzer sowie die Interviewerin beurteilt.
Ergebnisse: Das Durchschnittsalter der Hunde lag bei 4,8 Jahren, das der Katzen bei 6,8 Jahren. Das Gewicht reichte beim Hund von 2,2 bis 95 kg, bei der Katze von 2 bis 11 kg. Rund 52% der Hunde und Katzen waren übergewichtig (BCS 6–9). Zwischen der Beurteilung der Besitzer bzw. der Interviewerin gab es Differenzen. Viele Besitzer unterschätzten den BCS und erkannten vor allem beginnendes Übergewicht (BCS 6–7) nicht. 58% der Hundeund 90% der Katzenbesitzer verwendeten ausschließlich handelsübliche Fertigfutter, 35% bzw. knapp 10% kombinierten diese mit zusätzlichen Futtermitteln. Knapp 8% der Hundeund < 1% der Katzenbesitzer verfütterten selbst zubereitete Rationen. Ältere (> 7 Jahre) und kranke Hunde erhielten häufiger selbst hergestellte Rationen. Ältere Besitzer (≥ 46 Jahre) tendierten vermehrt dazu, das Futter selbst zuzubereiten, während die Schulbildung und die Berufstätigkeit keinen Einfluss auf die Fütterung hatten. Ein Zusammenhang zwischen Art der Fütterung und BCS bestand nicht. Besitzer mit geringerer Schulbildung sowie Hausfrauen und Rentner hatten häufiger übergewichtige Tiere. Futterbelohnungen erhielten 95% der Hunde und 65% der Katzen. Ältere und berufstätige Besitzer gaben prozentual seltener Belohnungen.
Schlussfolgerungen: Übergewicht ist das größte ernährungsbedingte Problem. Im Vergleich zu früheren Studien hat sich die Zahl übergewichtiger Tiere erhöht.
Klinische Relevanz: Tierbesitzer sollten frühzeitig auf Übergewicht hingewiesen werden, da sie den Beginn der Adipositas häufig nicht wahrnehmen. Die meisten Tierbesitzer verabreichen Belohnungen, was bei Diäten berücksichtigt werden muss.

Abstract
There is increasing evidence that endothelial dysfunction is involved in refractoriness of acute GvHD (aGvHD). Here we investigated the hypothesis that another endothelial complication, transplant-associated thrombotic microangiopathy (TMA), contributes to the pathogenesis of aGvHD refractoriness. TMA was retrospectively assessed in 771 patients after allogeneic stem cell transplantation (alloSCT). Incidences of TMA and refractory aGvHD were correlated with biomarkers of endothelial damage obtained before alloSCT for patients receiving or not receiving statin-based endothelial prophylaxis (SEP). Diagnostic criteria for TMA and refractory aGvHD were met by 41 (5.3%) and 76 (10%) patients, respectively. TMA was overrepresented in patients with refractory aGvHD (45.0 vs 2.3% in all other patients, P<0.001). TMA independently increased mortality. Elevated pretransplant suppressor of tumorigenicity-2 and nitrates along with high-risk variants of the thrombomodulin gene were associated with increased risk of TMA. In contrast, SEP abolished the unfavorable outcome predicted by pretransplant biomarkers on TMA risk. Patients on SEP had a significantly lower risk of TMA (P=0.001) and refractory aGvHD (P=0.055) in a multivariate multistate model. Our data provide evidence that TMA contributes to the pathogenesis of aGvHD refractoriness. Patients with an increased TMA risk can be identified pretransplant and may benefit from pharmacological endothelium protection.

Abstract
Owing to their role as vectors of malaria parasites, species of the Anopheles maculipennis complex (Diptera: Culicidae) Meigen were intensively studied in the past, but with the disappearance of malaria in Germany in the middle of the last century, the interest in this field of research declined. A comprehensive ecological analysis of the current species distribution for Germany is lacking. Between 2010 and 2013, a total of 1445 mosquitoes of the An. maculipennis complex were collected at 72 different sites in Germany. The samples comprise 722 single individuals as well as 723 individuals in 90 pools of up to 25 mosquitoes. All samples were analysed with newly developed species-specific qPCR assays for the identification of the four German species using nucleotide differences within the internal transcribed spacer 2 (ITS2) ribosomal DNA. All gathered data were used for species distribution modelling. The overall prevalence of An. messeae s.l. was highest with 98.89% of all pools; An. daciae with 6.93% of all individuals and An. messeae s.s. with 69.53%. The prevalence of the other two species was relatively low: An. maculipennis s.s. with 13.30% of all individuals (6.67% of all pools) and An. atroparvus with 1.80% of all individuals (1.11% of all pools).

Abstract
As a result of intensified globalization of international trade and of substantial travel activities, mosquito-borne exotic pathogens are becoming an increasing threat for Europe. In Germany some 50 different mosquito species are known, several of which have vector competence for pathogens. During the last few years a number of zoonotic arboviruses that are pathogenic for humans have been isolated from mosquitoes in Germany including Usutu, Sindbis and Batai viruses. In addition, filarial worms, such as Dirofilaria repens have been repeatedly detected in mosquitoes from the federal state of Brandenburg. Other pathogens, in particular West Nile virus, are expected to emerge sooner or later in Germany as the virus is already circulating in neighboring countries, e.g. France, Austria and the Czech Republic. In upcoming years the risk for arbovirus transmission might increase in Germany due to increased occurrence of new so-called "invasive" mosquito species, such as the Asian bush mosquito Ochlerotatus japonicus or the Asian tiger mosquito Aedes albopictus. These invasive species are characterized by high vector competence for a broad range of pathogens and a preference for human blood meals. For risk assessment, a number of mosquito and pathogen surveillance projects have been initiated in Germany during the last few years; however, mosquito control strategies and plans of action have to be developed and put into place to allow early and efficient action against possible vector-borne epidemics.

Abstract
BACKGROUND Incidence rates of lymphoma are usually higher in men than in women, and oestrogens may protect against lymphoma. METHODS We evaluated occupational exposure to endocrine disrupting chemicals (EDCs) among 2457 controls and 2178 incident lymphoma cases and subtypes from the European Epilymph study. RESULTS Over 30 years of exposure to EDCs compared to no exposure was associated with a 24% increased risk of mature B-cell neoplasms (P-trend=0.02). Associations were observed among men, but not women. CONCLUSIONS Prolonged occupational exposure to endocrine disruptors seems to be moderately associated with some lymphoma subtypes.

Abstract
BACKGROUND Each year in Germany, about 65,000 people are diagnosed with colorectal cancer (CRC) and more than 25,000 people die of the disease. The majority of these cases could be avoided by a more effective screening programme. Recently, a law came into force that offers a great opportunity in this regard. It calls for introducing an organised CRC screening programme in Germany, which includes an invitation system as well as further measures for quality assurance and programme evaluation. To realise this opportunity, challenges of implementation need to be considered. The aim of this review article is to elaborate the challenges of an organised CRC screening in Germany in order to derive the need for action regarding successful implementation. METHODS This review article is based on a selective literature search, including current guidelines and recommendations. RESULTS AND CONCLUSION In the context of CRC screening, but also by colonoscopies performed for other indications (e.g., due to symptoms), precancerous lesions (adenomas) are detected and removed in a relevant proportion of the target population, which requires a surveillance examination after 3 or 5 years according to current recommendations. Therefore, an efficient invitation system for CRC screening should be designed to allow for a flexible interval depending on previous findings, which differs from mammography screening with its fixed interval. A prerequisite would be the standardised documentation of all colonoscopies irrespective of the indication, given that a substantial proportion of colonoscopies in Germany are performed outside of the screening program. Still, the work load regarding documentation could be less than for mammography screening. Another challenge in terms of organisation results from the parallel offer of 2 different screening tools (colonoscopy and faecal occult blood test). To realise the potential of an organised CRC screening, it seems important to devote sufficient time and resources for developing an efficient and feasible concept, while there might be interim options to avoid further delay regarding the initial invitation of the target population. Given that expertise from, amongst others, gastroenterology, epidemiology, clinical chemistry and health communication is required, an interdisciplinary approach appears essential.

Abstract
Recent genome-wide association studies (GWAS) of Hodgkin lymphoma (HL) have identified associations with genetic variation at both HLA and non-HLA loci; however, much of heritable HL susceptibility remains unexplained. Here we perform a meta-analysis of three HL GWAS totaling 1,816 cases and 7,877 controls followed by replication in an independent set of 1,281 cases and 3,218 controls to find novel risk loci. We identify a novel variant at 19p13.3 associated with HL (rs1860661; odds ratio (OR)=0.81, 95% confidence interval (95% CI) = 0.76-0.86, P(combined) = 3.5 × 10(-10)), located in intron 2 of TCF3 (also known as E2A), a regulator of B- and T-cell lineage commitment known to be involved in HL pathogenesis. This meta-analysis also notes associations between previously published loci at 2p16, 5q31, 6p31, 8q24 and 10p14 and HL subtypes. We conclude that our data suggest a link between the 19p13.3 locus, including TCF3, and HL risk.

Abstract
BACKGROUND AND OBJECTIVE Considering the prolonged life-expectancies and the resulting demands that are placed on cancer patients and their relatives, the importance of specific counseling and support services including psycho-oncology, social services, nutritional, and exercise counseling has profoundly increased. The main focus of the current study was to evaluate the multidisciplinary health care needs of emotionally distressed cancer patients whoe were treated in a Comprehensive Cancer Center. METHODS AND STUDYGROUP: 831 out-patients were evaluated with regard to their psychological distress level and their multidisciplinary health care needs for specialist services of psycho-oncology, social services, nutritional, and exercise counseling using a tablet-PC assisted screening questionnaire. Separate analyses were completed for patients with and without psychological distress. RESULTS One third of the screened patients showed clinically relevant psychological distress. Health care needs for all specialist services were significantly greater among these patients compared to patients without psychological distress (all p-values < 0.005). The higher needs were foremost presented by the number of needed specialist services (p < 0.001): two thirds of the psychologically distressed patients demonstrated, besides the need for a psycho-oncological service, a need for two or three further specialist services, whereas among patients without psychological distress more than 70% showed a need for at most one specialist service. CONCLUSION Multidisciplinary health care needs of psychologically distressed cancer patients should be systematically addressed in a Comprehensive Cancer Center, and patients should be offered a coordinated and integrated health care program.

Abstract
The aim of this study was to distinguish the impacts of two different anthropogenic conditions using the honeybee Apis mellifera as a bioindicator associated with a battery of biomarkers previously validated in the laboratory. Both the urban (RAV, Ravine des Cabris) and semi-natural (CIL, Cilaos) sites in La Reunion Island were compared in order to assess the impacts of two types of local pollution using the discriminating potential of biomarkers. Hives were placed at the CIL and RAV sites and honeybees were collected from each hive every three months over one year. Honeybee responses were evaluated with respect to several biochemical biomarkers: glutathione-S-transferase (GST), acetylcholinesterase (AChE), alkaline phosphatase (ALP) and metallothioneins (MT). The results showed a significant difference between the localities in terms of GST, AChE and ALP activities, as regarding midgut MT tissue levels. Compared to the CIL site, ALP and MT tissue levels were higher at the RAV site, although AChE activity was lower. GST displayed more contrasted effects. These results strongly suggest that the honeybees based in the more anthropized area were subjected to sublethal stress involving both oxidative stress and detoxification processes with the occurrence of neurotoxic pollutants, amongst which metals were good candidates. A classification tree enabled defining a decision procedure to distinguish the sampling locations and enabled excellent classification accuracy (89%) for the data set. This field study constitutes a strong support in favour of the in situ assessment of environmental quality using honeybee biomarkers and validates the possibility of performing further ecotoxicological studies using honeybee biomarkers.

Abstract
OBJECTIVES We evaluated the association between occupational exposure to trichloroethylene (TCE) and risk of non-Hodgkin lymphoma (NHL) in a pooled analysis of four international case-control studies. METHODS Overall, the pooled study population included 3788 NHL cases and 4279 controls. Risk of NHL and its major subtypes associated with TCE exposure was calculated with unconditional logistic regression and polytomous regression analysis, adjusting by age, gender and study. RESULTS Risk of follicular lymphoma (FL), but not NHL overall or other subtypes, increased by probability (p=0.02) and intensity level (p=0.04), and with the combined analysis of four exposure metrics assumed as independent (p=0.004). After restricting the analysis to the most likely exposed study subjects, risk of NHL overall, FL and chronic lymphocytic leukaemia (CLL) were elevated and increased by duration of exposure (p=0.009, p=0.04 and p=0.01, respectively) and with the combined analysis of duration, frequency and intensity of exposure (p=0.004, p=0.015 and p=0.005, respectively). Although based on small numbers of exposed, risk of all the major NHL subtypes, namely diffuse large B-cell lymphoma, FL and CLL, showed increases in risk ranging 2-3.2-fold in the highest category of exposure intensity. No significant heterogeneity in risk was detected by major NHL subtypes or by study. CONCLUSIONS Our pooled analysis apparently supports the hypothesis of an increase in risk of specific NHL subtypes associated with occupational exposure to TCE.

Abstract
BACKGROUND The etiology of Hodgkin lymphoma (HL) remains incompletely characterized. Studies of the association between smoking and HL have yielded ambiguous results, possibly due to differences between HL subtypes. PATIENTS AND METHODS Through the InterLymph Consortium, 12 case-control studies regarding cigarette smoking and HL were identified. Pooled analyses on the association between smoking and HL stratified by tumor histology and Epstein-Barr virus (EBV) status were conducted using random effects models adjusted for confounders. Analyses included 3335 HL cases and 14 278 controls. RESULTS Overall, 54.5% of cases and 57.4% of controls were ever cigarette smokers. Compared with never smokers, ever smokers had an odds ratio (OR) of HL of 1.10 [95% confidence interval (CI) 1.01-1.21]. This increased risk reflected associations with mixed cellularity cHL (OR = 1.60, 95% CI 1.29-1.99) and EBV-positive cHL (OR = 1.81, 95% CI 1.27-2.56) among current smokers, whereas risk of nodular sclerosis (OR = 1.09, 95% CI 0.90-1.32) and EBV-negative HL (OR = 1.02, 95% CI 0.72-1.44) was not increased. CONCLUSION These results support the notion of etiologic heterogeneity between HL subtypes, highlighting the need for HL stratification in future studies. Even if not relevant to all subtypes, our study emphasizes that cigarette smoking should be added to the few modifiable HL risk factors identified.

Abstract
OBJECTIVE Horse meat is often used in the context of an elimination diet. For reasons of practicability some pet owners feed canned horse meat, which is commercially available. Based on a report of a cat with food allergy that displayed cervical spondylosis, the vitamin A content was analyzed in various horse meat products. MATERIAL AND METHODS The vitamin A (retinol) content was analyzed in 14 commercially available horse meat products. The content of metabolizable energy was calculated on the basis of the declaration by using estimation equations. RESULTS High amounts of vitamin A were found in some products for which liver, offal or animal by-products were labelled as contents. When feeding exclusively with one of these products, the vitamin A supply was just below the safe upper limit for cats while above the safe upper limit for dogs. CONCLUSION Labelling and content of all-meat-products should be thoroughly checked to identify products with high liver percentages. CLINICAL RELEVANCE An excessive vitamin A intake can occur when feeding with horse-meat products with a high liver content over a long period.

Abstract
BACKGROUND The two most common forms of non-Hodgkin lymphoma (NHL) exhibit different sex ratios: diffuse large B-cell lymphoma (DLBCL) occurs more frequently in men and follicular lymphoma (FL) more frequently in women. Looking among women alone, this pooled analysis explores the relationship between reproductive histories and these cancers. MATERIALS AND METHODS Self-reported reproductive histories from 4263 women with NHL and 5971 women without NHL were pooled across 18 case-control studies (1983-2005) from North America, Europe and Japan. Study-specific odd ratios (ORs) and confidence intervals (CIs) were estimated using logistic regression and pooled using random-effects meta-analyses. RESULTS Associations with reproductive factors were found for FL rather than NHL overall and DLBCL. In particular, the risk of FL decreased with increasing number of pregnancies (pooled OR(trend) = 0.88, 95% CI 0.81-0.96). FL was associated with hormonal contraception (pooled OR = 1.30, 95% CI 1.04-1.63), and risks were increased when use started after the age of 21, was used for <5 years or stopped for >20 years before diagnosis. DLBCL, on the other hand, was not associated with hormonal contraception (pooled OR = 0.87, 95% CI 0.65-1.16). CONCLUSIONS Hormonal contraception is associated with an increased risk of FL but not of DLBCL or NHL overall.

Abstract
Respiratory motion complicates radiotherapy treatment of thoracic and abdominal tumours. Simplified respiratory motions such as sinusoidal and single patient traces are often used to determine the impact of motion on respiratory management techniques in radiotherapy. Such simplifications only accurately model a small portion of patients, as most patients exhibit variability and irregularity beyond these models. We have preformed a comprehensive analysis of respiratory motion and developed a software tool that allows for explicit inclusion of variability. We utilize our realistic respiratory generator to customize respiratory traces to test the robustness of the estimate of internal gross target volumes (IGTV) by 4DCT and CBCT. We confirmed that good agreement is found between 4DCT and CBCT for regular breathing motion. When amplitude variability was introduced the accuracy of the estimate slightly, but the absolute differences were still < 3 mm for both modalities. Poor agreement was shown with the addition of baseline drifts. Both modalities were found to underestimate the IGTV by as much as 30% for 4DCT and 25% for CBCT. Both large and small drifts deteriorated the estimate accuracy. The respiratory trace generator was advantageous for examining the difference between 4DCT and CBCT IGTV estimation under variable motions. It provided useful implementation abilities to test specific attributes of respiratory motion and detected issues that were not seen with the regular motion studies. This is just one example of how the respiratory trace generator can be utilized to test applications of respiratory management techniques.

Abstract
The availability of respiratory synchronized PET (4DPET) imaging has enabled more accurate analysis of metabolic response since motion blur is minimized. We present our preliminary analysis of serial FDG 4DPET images acquired at weeks 0, 2, 4, and 7 during radiotherapy of seven stage II-III NSCLC patients. The tumor and nodal PTV of the week 0 images restrained a 4DPET image thresholding algorithm to automatically contour SUV levels ranging from 20 to 80% of the maximum SUV, creating an intensity volume histogram (IVH) for each week. These contours allowed analysis of PET volumes and standard PET metrics such as SUVmax and SUVmean . We found a trend for decreasing SUVmax and SUVmean over a treatment course in both the tumor and nodal regions. On average, the SUVmax within the tumor decreased by 17±13% (1 SD) after 2 weeks, 30±13% after 4 weeks, and 39±19% after 7 weeks of radiotherapy. Decreasing volume trends were also observed in the 20 to 80% max SUV autocontours, ranging from 26±29% to 50±40% respectively, over 7 weeks of treatment. Only one patient demonstrated an increase in FDG uptake within the tumor volume between week 0 and week 2 of treatment, and was also the only patient to recur locally at 3 months following treatment. Changes in tumor metabolism over the course of advanced NSCLC radiotherapy are quantifiable with serial FDG 4DPET imaging. Preliminary analysis suggests that variations in these trends could be useful in identifying non-responding patients that may require an alternative radiotherapeutic approach.

Abstract
Two case reports demonstrate the consequences of a deficient calcium supply in dogs. The first case describes an adult dog with a history of food allergy. The dog had been fed with an unbalanced elimination diet (no minerals and vitamins supplemented) over many years and was referred with the diagnosis of osteomalacia (rubber jaw) for optimization of his ration. The second case refers to a puppy which was fed a homemade diet without supplementing the missing minerals and vitamins and suffered a femur fracture after moderate physical impact. In both cases, the computer-aided ration calculation showed a suboptimal to severely deficient supply for several minerals and vitamins, in particular calcium whereas serum calcium levels were normal. Both dogs recovered after being fed a complete and balanced diet. In conclusion, a survey of the feeding using ration calculation is essential especially in the case of potential nutrition-related skeletal disorders. Serum calcium levels cannot be used as a tool to diagnose nutritional calcium deficiency.

Abstract
OBJECTIVE The aim of this study was to determine epidemiological data on the feeding of dogs and cats in Germany. MATERIAL AND METHODS A total of 865 dog owners and 243 cat owners were interviewed using standardised questionnaires about their animals (age, sex, weight, body condition, health) and feeding, including treats, additional supplements and reasons for food changes, together with data on the pet owners (age, sex, education, profession). The interviews took place in the waiting rooms of veterinarians, in dog schools, animal shelters and public parks as well as via the internet. Body condition scoring (BCS, scale 1-9) was performed separately by the pet owners and the interviewer. RESULTS The mean age of dogs was 4.8 years and of cats 6.8 years. The dogs' body weight ranged from 2.2kg (Pomeranian dog) to 95kg (Saint Bernard). The cats had a body weight from 2 to 11kg. Approximately 52% of dogs and cats were overweight (BCS6-9). Differences existed between the assessment by the owner and the interviewer. Many owners underestimated the body condition, in particular, moderate overweight was not recognised (BCS6-7). Commercial food was exclusively used by 58% of dog and 90% of cat owners, while 35% and 10%, respectively, combined these with additional feed. Nearly 8% of dog and <1% of cat owners fed their pets with home-made diets. Elderly (>7 years) and sick dogs received home-made diets more often. Older pet owners (≥ 46 years) fed their pets home-made diets more frequently. The education and profession of owners did not affect the percentage of home-made diets. There was no effect of the type of diet on BCS. Owners with a lower education as well as housewives and pensioners more often had overweight pets. Older owners and working owners gave treats less frequently. However, 95% of dogs and 65% of cats received treats. CONCLUSION Being overweight is the biggest dietary problem. In comparison to previous studies, the number of overweight pets has increased. CLINICAL RELEVANCE Pet owners should be advised early on excess weight, because the onset of being overweight is often not recognised. The majority of pet owners gives treats. Diets for the treatment of disease need to take this into account and offer solutions for treats.

Abstract
Deletions of chromosomal arms 1p and 19q are frequent in oligodendroglial tumours and linked to radio- and chemotherapy response as well as longer survival. The molecular mechanisms underlying this clinically important association are as yet unknown. Here, we studied the peroxiredoxin 1 (PRDX1) gene at 1p34.1 for promoter methylation and expression in primary gliomas and investigated its role in radio- and chemosensitivity of glioma cells in vitro. In total, we screened primary glioma tissues from 93 patients for methylation of the 5'-CpG island of PRDX1 by sodium bisulfite sequencing. PRDX1 mRNA and protein expression levels were determined in subsets of the tumours by quantitative PCR and western blot analysis, respectively. PRDX1 hypermethylation and reduced expression were frequently detected in oligodendroglial tumours and secondary glioblastomas, but not in primary glioblastomas. In oligodendroglial tumours, both PRDX1 hypermethylation and reduced mRNA expression were significantly associated with 1p/19q-deletion. Stable knockdown of PRDX1 by lentiviral transduction of short-hairpin (sh)RNA constructs significantly increased apoptosis and reduced cell viability of Hs683 glioma cells exposed to ionizing irradiation or temozolomide in vitro. Taken together, our findings indicate that epigenetic silencing of PRDX1 is frequent in 1p/19q-deleted oligodendroglial tumours and likely contributes to radio- and chemosensitivity of these tumours.

Abstract
AIM Faecal incontinence (FI) is a common disorder involving both the enteric (ENS) and central nervous systems (CNS). The aim of the study is to analyze neurophysiologically the central processing of emotions in children with FI, healthy controls and children with Attention-deficit hyperactivity disorder (ADHD). METHODS Fourteen children with FI and constipation, nine with non-retentive FI, 15 controls and 13 children with ADHD were examined. The methods included a physical exam, sonography, Child Behavior Checklist, a psychiatric interview and intelligence test. Acoustic evoked potentials were recorded according to standardized methodology. For the event-related potentials, 80 neutral, 40 positive and 40 negative pictures from the International Affective Picture System (IAPS), and 40 pictures depicting faeces were presented. RESULTS Children with FI had significantly more intense responses for most stimuli over the frontal, central and parietal regions compared to controls. Stool pictures did not evoke stronger responses than other stimuli. Children with constipation elicited stronger responses. Children with ADHD did not differ from controls. Acoustic evoked potentials were comparable in all groups. CONCLUSIONS Children with FI have increased responses in the processing of emotions. These can be interpreted as a neurobiological vulnerability, possibly due to the association of the ENS and CNS.

Abstract
From June 2006 to May 2007, mosquito surveys were conducted in Thanlyin Township, Yangon City, Myanmar, to determine factors influencing the abundance of Aedes aegypti (Stegomyia aegypti) during the rainy season. Both the biological and environmental factors were included in this study. Increase in the hatchability of egg, larval survival rate, the shortened larval life-span and increased pupation rates supplemented by rainfall (i.e. continuous flooding of the containers, stimulate the continuous hatching of eggs) were observed for correlation with the increase in population density of Ae. aegypti during the rainy season in the study area. Control strategy of Ae. aegypti to analyze the infestation in the community (study area) with larval Ae. aegypti, integrated management measures including health education, attitudes and practices regarding dengue and dengue haemorrhagic fever, transmission of the disease and possible preventive measures, reduction of breeding sites and testing the efficacy of Bacillus thuringiensis israelensis (B.t.i.) with respect to the reduction level of Ae. aegypti larvae in breeding sources, were taken into consideration.

Abstract
The whitefly Bemisia tabaci is a pest vector of begomoviruses on crops worldwide. Bemisia tabaci is composed of a complex of cryptic species which barely interbreed. An exception is the Ms from the South West Indian Ocean (SWIO), which crosses in low proportions with the exotic B. The Ms, together with B and Q is part of the same phylogenetic clad. To infer the genetic structure, the geographical range and putative origin of this putative species, microsatellite data and mitochondrial DNA (cytochrome oxydase I) sequences were analysed on an extensive sample set, including all the islands of the region and samples from mainland Africa. Only B and Ms populations were detected across these islands. The exotic B was found only on the islands of Réunion and Mauritius, whereas the Ms is found on all the SWIO islands. Very high isolation by distance was found for the Ms populations between islands of the SWIO, suggesting a long period of presence in this region. Ms populations from mainland Africa had a higher COI diversity than the Ms of the SWIO islands. This diversity is correlated with size and geological ages of the SWIO islands. The population genetic data obtained are in accordance with an origin of Ms in Africa, followed by its expansion and evolution across the SWIO islands prior to human arrival, confirming the status of Ms as indigenous in the SWIO islands.
