Background In the follow-up computed tomography (CT) examinations of patients who had undergone gastrectomy for gastric malignancy in our center, we noticed by chance that there was an isolated increase in the diameter of the main portal vein (MPV) without other radiological findings of portal hypertension.

Background: The panel infrastructure Health in Germany, which is currently being set up, is geared towards the needs of public health research in Germany. The panel will consist of extensive probability and non-probability samples. This infrastructure will be used to collect survey data, measurement data and laboratory data to describe the health situation on an ongoing basis and make them available promptly. Methods: For the initial drawing of the probability sample, the sampling frame of the residents’ registration offices (EMA) established in Germany is used. The study design follows a mixed-mode approach in which the invited persons can choose whether to participate in the survey online or in paper form. Four surveys per year are planned for the regular operation of the panel (regular annual wave). Ad-hoc studies on specific topics or acute issues are also possible. Conclusions: The panel provides a new infrastructure for continuous epidemiological studies to monitor the health of the population in Germany. This data basis strengthens the health monitoring and health reporting of the federal government, enabling a prompt and adaptable response to emerging data needs.

OBJECTIVE: The aim of this study was to identify the occupational risk for a SARS-CoV-2 infection in a nationwide sample of German workers during the first wave of the COVID-19 pandemic (1 February–31 August 2020). METHODS: We used the data of 108 960 workers who participated in a COVID follow-up survey of the German National Cohort (NAKO). Occupational characteristics were derived from the German Classification of Occupations 2010 (Klassifikation der Berufe 2010). PCR-confirmed SARS-CoV-2 infections were assessed from self-reports. Incidence rates (IR) and incidence rate ratios (IRR) were estimated using robust Poisson regression, adjusted for person-time at risk, age, sex, migration background, study center, working hours, and employment relationship. RESULTS: The IR was 3.7 infections per 1000 workers [95% confidence interval (CI) 3.3–4.1]. IR differed by occupational sector, with the highest rates observed in personal (IR 4.8, 95% CI 4.0–5.6) and business administration (IR 3.4, 95% CI 2.8–3.9) services and the lowest rates in occupations related to the production of goods (IR 2.0, 95% CI 1.5–2.6). Infections were more frequent among essential workers compared with workers in non-essential occupations (IRR 1.95, 95% CI 1.59–2.40) and among highly skilled compared with skilled professions (IRR 1.36, 95% CI 1.07–1.72). CONCLUSIONS: The results emphasize higher infection risks in essential occupations and personal-related services, especially in the healthcare sector. Additionally, we found evidence that infections were more common in higher occupational status positions at the beginning of the pandemic.

Sex/gender diversity is increasingly recognised by society and should be taken into account more in population-representative studies, as they are important data sources for targeting health promotion, prevention and care. In 2019, the Robert Koch Institute started a population-representative health survey with the study Health in Germany Update (GEDA 2019/2020-EHIS) with a modified, two-stage measures of sex/gender. The survey covered sex registered at birth and gender identity with an open response option. This article describes the aims, the procedure and the experiences with the operationalisation of sex/gender and the results. Out of 23,001 respondents, 22,826 persons are classified as cisgender, 113 persons as transgender and 29 persons as gender-diverse. 33 respondents were counted as having missing values. A survey of interviewers showed that the two-stage measures of sex/gender had a high level of acceptance overall and that there were only a few interview drop-outs. On the basis of previous experience, the modified query can be used for further surveys, but should also be adapted in perspective. For this purpose, participatory studies are desirable that focus on how the acceptance of measures of sex/gender can be further improved and how hurtful experiences in the context of the questions asked can be avoided.

We thank van Tongeren et al for responding to our study on occupational disparities in SARS-CoV-2 infection risks during the first pandemic wave in Germany (1). The authors address the potential for bias resulting from differential testing between occupational groups and propose an alternative analytical strategy for dealing with selective testing. In the following, we want to discuss two aspects of this issue, namely (i) the extent and reasons of differential testing in our cohort and (ii) the advantages and disadvantages of different analytical approaches to study risk factors for SARS-CoV-2 infection. Our study relied on nationwide prospective cohort data including more than 100 000 workers in order to compare the incidence of infections between different occupations and occupational status positions. We found elevated infection risks in personal services and business administration, in essential occupations (including health care) and among people in higher occupational status positions (ie, managers and highly skilled workers) during the first pandemic wave in Germany (2). Van Tongeren’s et al main concern is that the correlations found could be affected by a systematic bias because people in healthcare professions get tested more often than employees in other professions. A second argument is that better-off people could be more likely to use testing as they are less affected by direct costs (prices for testing) and the economic hardship associated with a positive test result (eg, loss of earnings in the event of sick leave). We share the authors’ view that differential testing must be considered when analysing and interpreting the data. Thus, in our study, we examined the proportion of tests conducted in each occupational group as part of the sensitivity analyses (see supplementary figure S1, accessible at www.sjweh.fi/article/4037). As expected, testing proportions were exceptionally high in medical occupations (due to employer requirements). However, we did not observe systematic differences among non-medical occupations or when categorising by skill-level or managerial responsibility. This might be explained by several reasons. First, SARS-CoV-2 testing was free of charge during the first pandemic wave in Germany, but reporting a risk contact or having symptoms was a necessary condition for testing ( https://www.bundesgesundheitsministerium.de/coronavirus/chronik-coronavirus.html (accessed 5 September 2022). The newspaper article cited by van Tongeren et al is misleading as it refers to a calendar date after our study period. Second, different motivation for testing due to economic hardship in case of a positive test result is an unlikely explanation, because Germany has a universal healthcare system, including paid sick leave and sickness benefits for all workers (3). Self-employed people carry greater financial risks in case of sickness. We therefore included self-employment in the multivariable analyses to address this potential source of bias. While the observed inverse social gradient may be surprising, it actually matches with findings of ecological studies from Germany (4, 5), the United States (6, 7) as well as Spain, Portugal, Sweden, The Netherlands, Israel, and Hong Kong (8), all of which observed higher infection rates in wealthier neighbourhoods during the initial outbreak phase of the pandemic. One possible explanation is the higher mobility of managers and better educated workers, who are more likely to participate in meetings and engage in business travel and holiday trips like skiing. Given the increasing number of studies providing evidence for this hypothesis, we conclude that the inverse social gradient in our study likely reflects different exposure probabilities and is not a result of systematic bias. This also holds true for the elevated infection risks in essential workers, which is actually corroborated by a large body of research (9–11). Regarding differential likelihood of testing, van Tongeren et al state that “[i]t is relatively simple to address this problem by using a test-negative design” (1). As van Tongeren et al describe, this is a case–control approach only including individuals who were tested (without considering those who were not tested). However, the proposed analytical strategy can lead to another (more serious) selection bias if testing proportions and/or testing criteria differ between groups (12). This can be easily illustrated when comparing the results based on a time-incidence design with those obtained by a test-negative design as shown in table 1 (see PDF). Both approaches show similar results in terms of vertical occupational differences. Infection was more common if individuals had a high skill level or had a managerial position, but associations were stronger in the time-incidence design and did not reach statistical significance in the test-negative design (as indicated by the confidence intervals overlapping “1”). Unfortunately, the test-negative approach relies on a strongly reduced sample size and thus results in greater statistical uncertainty and loss of statistical power (13). In contrast, the test-negative design yields a different picture when estimating the association between essential occupation and infection risk: In this analysis, essential workers did not differ from non-essential workers in their chance of being infected with SARS-CoV-2 (the test-negative design even exhibits a lower chance for essential workers). This is rather counter-intuitive and is not in accordance with what we know about the occupational hazards of healthcare workers during the pandemic (14). The main problem is that proportions of positive tests are highly unreliable when testing proportions and/or testing criteria differ between groups. As essential workers were tested more often without being symptomatic (due to employer requirements), a lower proportion of positive tests in this group does not necessarily correspond to a lower risk of infection. Consequently, we are not convinced that the test-negative design should be the ‘gold standard’ for studying risk factors for SARS-CoV-2 infections (15). Especially problematic is the loss of statistical power (increasing the probability of a type II error) and the low validity of the test-positivity when test criteria and/or test proportions differ between groups.

Gastric cancer is one of the most common causes of cancer-related death. It requires multimodal treatment and surgery is the most effective treatment modality. Radical surgery includes total or subtotal gastrectomy with lymph node dissection. The extent of lymphadenectomy still remains controversial. Eastern surgeons have performed D2 or more extended lymphadenectomy while their Western colleagues have performed more limited lymph node dissection. However, the trend has been changing in favour of D2 lymph node dissection in both hemispheres. Currently, D2 is the recommended type of lymphadenectomy in experienced centres in the west. In Japan, D2 lymph node dissection is the standard surgical approach. More extensive lymphadenectomy than D2 has not been found to be associated with improved survival and generally is not performed. Bursectomy and splenectomy are additional controversial issues in surgical performance, and trends regarding them will be discussed. The performance of bursectomy is controversial and there is no clear evidence of its clinical benefit. However, a trend toward better survival in patients with serosal invasion has been reported. Routine splenectomy as a part of lymph node dissection has largely been abandoned, although splenectomy is recommended in selected cases. Minimally invasive surgery has gained wide popularity and indications for minimally invasive procedures have been expanding due to increasing experience and improving technology. Neoadjuvant therapy has been shown to have beneficial effects and seems necessary to provide a survival benefit. Diagnostic laparoscopy should be kept in mind prior to treatment

IgG antiglobulins in human sera were measured by single radial diffusion in agar after elution from ethyl chloroformate insolubilized immunosorbents of rabbit or human IgG. With both immunosorbents seronegative and seropositive rheumatoid sera contained significantly higher levels of IgG antiglobulins than did sera from healthy adults. Attempts to measure antiglobulins interacting specifically with the pFc' half of the Fc region were not successful due to an unacceptably high degree of non-antibody binding. [ABSTRACT FROM AUTHOR]

Colonic solitary plasmacytoma is a rare disease, with few reports occurring in the literature. Solitary plasmacytoma is defined as a plasma cell tumour with no evidence of bone marrow infiltration. Plasmacytoma can present as a solitary tumour in bone or in other parts of the body. The gastrointestinal tract is rarely the site of the disease. We report on the case of a 51-year-old man presenting with a colonic symptomatic mass with unclear biopsy results. A resected specimen showed a solitary plasmacytoma. Surgical resection was an adequate treatment modality in this case. Endoscopic resection, radiotherapy, and chemotherapy are also preferred treatments in selected gastrointestinal plasmacytoma cases.

Background: Factors affecting liver regeneration are still relevant. The purpose of this study is to investigate the effect of nebivolol treatment on liver regeneration in rats in which 70% partial hepatectomy was performed., Methods: Three groups were created: the control group, the low dose group, and the high dose group, with 20 rats in each group and 70% hepatectomy was performed in all rats. Immediately after partial liver resection, 2 mL physiological saline solution was administered to the control group via oral gavage, 0.5 mg/kg nebivolol was administered via oral gavage to the low dose group and 2 mg/kg nebivolol was administered via oral gavage to the high dose group. On the 1 st and 5 th days after liver resection, 10 subjects were sacrificed from each group, and liver weights and the mitotic count and Ki-67 were measured., Results: Regenerating liver weight on the 1 st and 5 th days after partial hepatectomy was statistically different in the low dose and high dose nebivolol groups compared to the control group. Mitotic count on the 1 st day after partial hepatectomy was significantly higher in the low dose and high dose nebivolol groups than the control group. There was no statistically significant difference detected between the three groups for the 5 th day. On the 1 st day, Ki-67 rates were significantly higher in both groups given nebivolol than the control group. However, 5 th day results were not statistically significant., Conclusion: Nebivolol increases regeneration after partial hepatectomy in rats., (Copyright © 2016. Published by Elsevier Taiwan.)

Measles virus (MV) vectors are promising candidates for designing new recombinant vaccines since the parental live vaccines have a well-known safety and efficacy record. Like all viral vectors, the MV vector efficacy in inducing a protecting immune answer could be affected by the pre-existing immunity among the human population. In order to determine the optimal immunization route and regimen, we mimicked a MV pre-immunity by passively administrating MV neutralizing antibodies (MV-nAb) prior intramuscular (i.m.) and/or intranasal (i.n.) immunization with recombinant MV expressing the SIV-gag antigen (rMV-SIVgag). Our results revealed that 500 mIU of MV-nAb allowed the induction of a humoral and cellular immune response against the vector and the transgene, while higher titers of the MV-nAb were significantly inhibitory. In a prime-boost regimen, in the presence of MV-nAb, the intranasal-intramuscular (i.n.-i.m.) or intramuscular-intramuscular (i.m.-i.m.) routes induced higher humoral immune responses against the vector and the transgene (SIV-gag). In naive animals, cellular immune response was significantly higher by i.m. immunization; however, MV pre-immunity did not seem to affect the cellular immune response after an i.n. immunization.   In summary, we show that a pre-existing immunity of up to 500 mIU anti-MV neutralizing antibodies had little effect on the replication of rMV and did not inhibit the induction of significant humoral and cellular immune responses in immune-competent mice.

The measles virus vaccine (MVbv) is a clinically certified and well-tolerated vaccine strain that has been given both parenterally and mucosally. It has been extensively used in children and has proven to be safe and effective in eliciting protective immunity. This specific strain was therefore chosen to generate a measles viral vector. The genome of the commercial MVbv vaccine strain was isolated, sequenced and a plasmid, p(+)MVb, enabling transcription of the viral antigenome and rescue of MVb, was constructed. Phylogenic and phenotypic analysis revealed that MVbv and the rescued MVb constitute another evolutionary branch within the hitherto classified measles vaccines. Plasmid p(+)MVb was modified by insertion of artificial MV-type transcription units (ATUs) for the generation of recombinant viruses (rMVb) expressing additional proteins. Replication characteristics and immunogenicity of rMVb vectors were similar to the parental MVbv and to other vaccine strains. The expression of the additional proteins was stable over 10 serial virus transfers, which corresponds to an amplification greater than 10 ( 20) . The excellent safety record and its efficient application as aerosol may add to the usefulness of the derived vectors.

Recombinant measles viruses (rMV) based on the live attenuated measles vaccine strain (MVb) expressing antigens of HIV-1 clade B were generated by reverse genetics. Recombinants expressing single or double antigens of HIV-1 (rMV-HIV) were genetically highly stable on human diploid cells. The production process of these viruses was essentially similar to the parental MV strain, yielding comparative end titers. Immunization of tg-mice by different regimens and formulations showed potent humoral and cellular immune responses against MV and HIV antigens. Recombinant MV-HIV expressing Gag protein conferred protective immunity in tg-mice after a high-dose pseudochallenge with recombinant vaccinia virus. In addition, rMV-HIV boosted anti-HIV antibodies, in the presence of pre-existing anti-vector antibodies.

Background: We aimed to determine the status of and factors associated with adolescent health care delivery and training in Europe on behalf of the European Paediatric Association-UNEPSA., Materials and Methods: A questionnaire was mailed to the presidents of 48 national paediatric societies in Europe. For statistical analyses, non-parametric tests were used as appropriate., Results: Six of the countries had a paediatric (PSPCA), 14 had a combined and nine had a general practitioner/family doctor system for the primary care of adolescents (GP/FDSA). Paediatricians served children 17 years of age or older in 15 and 17, up to 16 years of age in three and six, and up to 14 years of age in six and six countries in outpatient and inpatient settings, respectively. Fifteen and 18 of the countries had some kind of special inpatient wards and outpatient clinics for adolescents, respectively. Twenty-eight of the countries had some kind of national/governmental screening or/and preventive health programmes for adolescents. In countries with a PSPCA, the gross national income (GNI) per capita was significantly lower than in those with a GP/FDSA, and the mean upper age limit of adolescents was significantly higher than in those with the other systems. In the eastern part of Europe, the mortality rate of 10-14 year olds was significantly higher than that in the western part (p=0.008). Training in adolescent medicine was offered in pre-graduate education in 14 countries in the paediatric curriculum and in the context of paediatric residency and GP/family physician residency programmes in 18 and nine countries, respectively. Adolescent medicine was reported as a recognised subspecialty in 15 countries and as a certified subspecialty of paediatrics in one country. In countries with a PSPCA, paediatric residents were more likely to be educated in adolescent medicine than paediatric residents in countries with a GP/FDSA., Conclusion: The results of the present study show that there is a need for the reconstruction and standardisation of adolescent health care delivery and training in European countries. The European Paediatric Association-UNEPSA could play a key role in the implementation of the proposals suggested in this paper.

Objective: The objective of the study was to determine the prevalence of sexual abuse in female adolescents in Istanbul, Turkey from data collected as part of a school-based population study on health and health behaviors., Method: A stratified cluster sampling procedure was used for this cross-sectional study. The study sample included 1,955 randomly selected 9th through 11th grade female students attending 26 randomly-selected high schools in Istanbul. A self-report questionnaire was administered anonymously in the classroom. Information on sexual abuse history was collected through the questions investigating "touching" and "intercourse.", Results: Of 1,955 female students, 1,871 (95.7%) provided answers to the questions addressing unwanted sexual experience. Of these, 250 (13.4%) reported sexually abusive experiences. Two hundred and thirteen (11.3%) students reported that someone touched their private parts in a way they did not like; 91 (4.9%) reported they were forced to have sexual intercourse; 54 (3.0%) reported both types of sexual abuse. Incest was reported by 1.8% of the subjects. Ninety-three percent of the perpetrators were reported to be male., Conclusions: This is the first reported school-based study to determine the prevalence of sexual abuse in Turkey. The results show that at least 13.4% of female high school students disclosed having experienced sexual abuse during childhood.

Unlabelled: The objective of this study was to investigate health status of Turkish adolescents and to determine the factors affecting their self perceptions of health. The subjects of the study were 4,153 grade 9-11 students from 26 randomly selected high schools in Istanbul. In total, 78% (n = 3231) and 62% (n = 2537) of the students reported that they were feeling healthy and happy, respectively. Prevalence of headache, abdominal pain and backache; feeling low, irritable, nervous and dizzy; medication use for headache, abdominal pain and nervousness were higher in females than in males (P < 0.05 for each comparison). Prevalence of difficulty in getting to sleep and medication use for it were quite similar in both genders. Perceived higher socio-economic status, feeling happy and exercising longer than 2-3 h a week were found as protective factors related to feeling healthy for both genders. In females, ease of talking to mother and perceived adequate parental support on school matters and in males, ease of talking to father and satisfaction with body size were protective factors related to feeling healthy, respectively. Cigarette smoking and having headaches put feeling healthy at risk in both genders. In females, feeling left out of things, having backache and dizziness and medication use for nervousness and in males, feeling pressured by school work, abdominal pain and difficulty in getting to sleep were risk factors related to feeling healthy, respectively., Conclusion: the findings of this study suggest that a significant number of Turkish adolescents perceive themselves as not very healthy and experience psychosomatic symptoms. Perception of health differed to some extent according to gender. Programmes promoting health-related activities and coping strategies with parental participation need to be developed for improving health in high school students., (Copyright 2004 Springer-Verlag)

The aim of this study was to evaluate the prevalence, behavioral patterns and correlates of regular alcohol drinking in high school students. This cross-sectional study involved the completion of a modified version of "Health Behavior in School Age Children" (HBSC 1997/1998) questionnaire by 4,153 grade 9-11 students from 26 randomly selected high schools in Istanbul. Chi-square test, Spearman correlation test and forward stepwise multiple logistic regression model were used for statistical analyses as appropriate. Overall, 61% of students were experimental drinkers, and 46% of the students were current drinkers. There was a significant difference between female and male students with respect to reporting current alcohol drinking at grade 9 and 11 (p > 0.05 for each comparison). Regular drinking was reported by 6% of students. Male students were more likely than female students to report regular drinking at each grade (p < 0.01 for each comparison). Nineteen percent of the students reported that they had been really drunk at least once during their lifetime. Malestudents were more likely than female students to report an occasion of drunkenness at each grade (p < 0.05 for each comparison). All types of drinking behavior rates tended to increase across grades for both genders (p < 0.05 for each comparison). In logistic regression analysis the following were all independently associated with regular drinking: being in grade 11, smoking cigarettes currently, lifetime drug use, bullying others, being sexually active, playing computer games > or = 4 h/week, exercising < or = 1 h/week, spending > or = four evenings with friends, at ease in talking to same gender friends, tiredness in the morning, perceived as good-looking/beautiful, higher educational level of the mother and perceived poor academic achievement. The results of this study showed that alcohol consumption is prevalent among high school students. There is therefore a need for school-based alcohol prevention programs which also deal with family and peer influences on drinking.

Objective: To determine values of bone density of Turkish infants under one year of age., Design: Cross sectional., Methods: This study included 1, 2, 4, 6, 9 and 12 months old 164 male and female healthy infants who were evaluated by dual energy X-ray absorbtiometry., Results: The values for each age were computed. There was no significant difference between boys and girls. A significant relationship was found between bone mineral density, bone mineral content, total body calcium and calcium/body surface, and age, height, body weight, head circumference and body surface area. Multiple regression analysis showed that body mineral density was affected by weight, height, head circumference and body mass index. Body mineral content and total calcium content were affected by weight and height., Conclusion: The results will serve as reference values for healthy 1-12 months old Turkish infants.

The aim of this study was to evaluate the presence of transferred measles antibodies and seronegativity rates during early infancy in premature newborns whose mothers had infection-induced immunity. The premature group was composed of 22 and 35 newborns of gestational ages < 32 wk and > 32 wk, respectively, and the control group consisted of 28 term newborns. Enzyme-linked immunosorbent assay (ELISA) was used for the qualitative detection of IgG antibodies to measles virus. Mean cord blood relative values were significantly lower in both premature groups, < or = 32 wk (p < 0.0001) and > 32 wk (p < 0.001), when compared with term infants. No seronegative infant was found in the premature group at 2 mo of age. At 4 mo, the seronegativity rate was 27% for premature infants < or = 32 wk and 35% for those > 32 wk. At 6 mo, seronegativity increased to 86% and 74% for premature infants born at gestational ages < or = 32 wk and > 32 wk, respectively. Forty-six percent of the term infants became seronegative at that age. The differences between term infants and those in the two premature groups were statistically significant (p < 0.05 and p < 0.005). Premature infants, regardless of their prematurity degree, were thought to be more susceptible to measles infection than term ones at the age of 6 mo. Policies for their protection from measles infection are still to be investigated.

Intraventricular hemorrhage (IVH) originating from germinal matrix is the major brain injury of the premature. We studied IVH incidence and risk factors which are implied in this pathology in newborns, hospitalized in the neonatal intensive care unit (NICU) of istanbul University Cerrahpaşa Faculty of Medicine. Ninety-seven premature newborns with a birth weight of less than 2500 g were examined systematically with cranial ultrasonography (CU). Mean birthweight was 1540 +/- 430 g (720-2450) and gestational age 31.6 +/- 2.4 weeks (26-37). IVH was diagnosed in 40 cases (41%). The significant risk factors are prematurity (gestational age < 33 weeks), artificial ventilation and infusion of fresh frozen plasma.

Autopsy was performed on 601 out of 654 (91.9%) fetus and newborn cases of death which occurred during a four-year period between 1988-1991 at Istanbul University Cerrahpaşa Faculty of Medicine, Gynecology Department and Neonatal Unit. According to autopsy findings, among the main causes of death in newborns were infection, hyaline membrane disease, congenital anomalies, perinatal hypoxia and immaturity, and in the fetal period, perinatal hypoxia, asphyxia and congenital anomalies. In these cases, when pathologic and clinical findings were examined, it was observed that in 204 out of 301 newborn cases (67.8%) the clinical findings were well correlated with the autopsy findings; in 97 (32.2%) of the remaining cases the main disease and primary causes of death could not be determined through clinical findings; in 69 (23%) cases, in addition to the clinical diagnosis on autopsy, minor defects were determined on autopsy which were not directly related to death. When clinical and autopsy findings were compared, diagnoses with the highest discordance were pulmonary hemorrhage infection and intracranial hemorrhage.
