Abstract
Hepatitis B virus (HBV), Hepatitis C virus (HCV), and Hepatitis E Virus (HEV) are highly endemic in several African countries including Nigeria with adverse effects on pregnancy outcomes resulting in fatality. This study aimed to determine the viral hepatitis in pregnant women attending antenatal clinic, AMTHI. Informed consent questionnaire was administered before blood collection via venipuncture. a total of 904 pregnant women plasma samples were tested for HBV, HCV, and HEV using ELISA kit. Data was analyzed using packages within SPSS software and P ≤ 0.05 was considered significant. Out of 904 samples analyzed, the overall prevalence of hepatitis infections among pregnant women attending antenatal clinic in AMTHI was 66(7.3%). High prevalence of the hepatitis infections was found among young women within the age group 21-30 which might be associated with active sex, intravenous drug use, sharing of sharp objects and alcoholism. Blood group O Positive had the highest prevalence of hepatitis. There was statistical significance between blood group and HBsAg infection (P < .05). Genotype AA women had highest prevalence of hepatitis. This study showed significant association between HBsAg, HCV, and HEV positive status with blood group O positive and Genotype AA pregnant women.

Postgrad Med J 2016; 92:510-3.

Abstract
OBJECTIVE To determine changes in hepatitis B virus (HBV) prevalence across three different time periods in pregnant women. METHODS This was a retrospective study of pregnant women attending four healthcare centres between January 1995 and May 2015. Data for serum hepatitis B surface antigen (HBsAg) and anti-HBs levels were collected from routine antenatal screening records. The 20-year study was divided into three periods: 1995-2001, 2002-2008 and 2009-2015. The results are presented by the women's age and gravidity as possible determinants of HBV infection. RESULTS 7605 pregnant women (56.0% primigravidae) (mean age 23.4±4.8 years) were tested for markers of HBV infection. 3010 pregnant women were screened between 1995 and 2001, 2995 between 2002 and 2008, and 1600 between 2009 and 2015. The overall prevalence of HBsAg and anti-HBs positivity in the 7605 pregnant women was 1.5% (n=114) and 11.5% (n=877), respectively. Regarding temporal change in the prevalence of HBV markers, HBsAg decreased significantly from 2.6% to 0.8% (p<0.01), while anti-HBs increased significantly from 9.5% to 17.5% (p<0.01), between the first and last study periods. Multigravidae and older women had higher HBsAg and anti-HBs positivity compared to primigravidae. CONCLUSIONS The data suggest that the prevalence of HBsAg positivity is gradually decreasing among pregnant women, while the level of HBsAg antibody seropositivity is lower than expected. HBV carrier rate increases with increasing age and gravidity. In addition to the national HBV immunisation programme, the prevention of perinatal transmission should also be prioritised to decrease the HBV pool of infection.

Abstract
This study investigates the difference in cancer mortality rates between migrant groups and the native Dutch population, and determines the extent of convergence of cancer mortality rates according to migrants' generation, age at migration and duration of residence. Data were obtained from the national cause of death and population registries in the period 1995-2000. We used Poisson regression to compare the cancer mortality rates of migrants originating from Turkey, Morocco, Surinam, Netherlands Antilles and Aruba to the rates for the native Dutch. All-cancer mortality among all migrant groups combined was significantly lower when compared to that of the native Dutch population (RR = 0.55, CI: 0.52-0.58). For a large number of cancers, migrants had more than 50% lower risk of death, while elevated risks were found for stomach and liver cancers. Mortality rates for all cancers combined were higher among second generation migrants, among those with younger age at migration, and those with longer duration of residence. This effect was particularly pronounced in lung cancer and colorectal cancer. For most cancers, mortality among second generation migrants remained lower compared to the native Dutch population. Surinamese migrants showed the most consistent pattern of convergence of cancer mortality. The generally low cancer mortality rates among migrants showed some degree of convergence but did not yet reach the levels of the native Dutch population. This convergence implies that current levels of cancer mortality among migrants will gradually increase in future years if no specific preventive measurements are taken.

Abstract
PURPOSE To detect seroconversion of hepatitis B vaccine and antibody waning 3 years after vaccination in children immunized according to the World Health Organization schedule and its relationship to the mother's serostatus during pregnancy. METHODS A serological study was carried out in São José dos Campos. Blood samples from pregnant women were taken for hepatitis B marker serology. To evaluate seroconversion in infants born to these women, serology was performed 1 month after they were vaccinated with recombinant vaccine. Another group of children was evaluated 3 years after being immunized. RESULTS Among 224 pregnant women, 0.9% were positive for hepatitis B surface antigen, 8.0% for antibodies to the surface antigen, and 4.5% for antibodies to the virus core. Seroconversion among 174 infants was as follows: absent in 18 children (10.35%), low level in 15 (8.62%), intermediate level in 26 (14.94%), and a high level (good response) in 115 (66.09%). Antibody positivity after 3 years was as follows: absent in 8 children (7.92%), low level in 51 (50.5%), intermediate level in 20 (19.8%), and high level in 22 (21.78%). Considering the age that the vaccine was administered, a significant proportion of non-seroconverters was found among children who had received the complete 3-dose schedule before 9 months (P = 0.023). Another factor that significantly contributed to the lack of seroconversion was the presence of any serological marker for hepatitis B during pregnancy (P = 0.044). CONCLUSIONS Data gathered in this work show that the immunization schedule for hepatitis B in low or moderate prevalence areas should be revised in order to optimize seroconversion.

Abstract
Cancer mortality among the 2.1 million Turks residing in Germany is assumed to change from a pattern typical for a developing country towards one of an industrialised country. To test this hypothesis, we compared age-standardised cancer mortality rates among Turkish residents and (West) Germans using death registration data. In addition, we assessed proportional cancer incidence ratios among Turkish cases (n=144) in a German population-based cancer registry. All-cancer mortality 1992-1997 (per 100000) was 34.8 (n=4192) among Turkish men (Germans: 72.3) and 21.5 (n=1862) among Turkish women (Germans: 52.4). Over time, gastric and lung cancer mortality increased among Turkish men, as did breast cancer mortality among Turkish women. The proportional cancer incidence (PCIR) for stomach cancer among men was 2.9 (95% Confidence Interval (CI): 1.7-4.8), and that for breast cancer among women was 0.7 (95% CI: 0.4-1.1). Turks had an increased proportional incidence ratio for non-Hodgkin's lymphoma. Our findings partly support a transition of cancer patterns among Turks in Germany.

Abstract
A population-based cancer registry, covering the province of Izmir (population 2.7 million, 1993-1994) in Western Turkey was established in 1992. Results for 1993-1994 are presented. Overall cancer incidence was higher in males than in females (age-standardised rates 157.5 and 94.0 per 100000, respectively), as in previous non-population-based series. The principal cancers in males were tobacco-related - lung (age-standardised incidence rate (ASR) 61.6), bladder (ASR 11.0) and larynx (ASR 10.6), consistent with the high prevalence of smoking, and use of traditional high-tar tobaccos. Skin cancers were also relatively common (ASR 11.5 for cancers excluding melanoma). Gastrointestinal cancers were relatively rare. In women, breast cancer was by far the most common malignancy (ASR 24.4); cervical cancer was relatively rare (ASR 5.4). There is probably an underestimate of incidence, due to an inability to use data from certain sources (e.g. death certificates), resulting in a rather high proportion of histologically verified cases (93.7% overall). Nevertheless, the overall profile is an accurate reflection of incidence in this region of Turkey and provides much of the information required for planning strategies to control cancer.
