Is the association of birth weight with premenopausal breast cancer risk mediated through childhood growth?
No full textSeveral studies have found positive associations between birth weight and breast cancer risk at premenopausal ages. The mechanisms underlying this association are not known, but it is possible that it may be mediated through childhood growth. We examined data from a British cohort of 2176 women born in 1946 and for whom there were prospective measurements of birth weight and of body size throughout life. In all, 59 breast cancer cases occurred during follow-up, 21 of whom were known to be premenopausal. Women who weighed at least 4 kg at birth were five times (relative risk (RR)=5.03; 95% confidence interval=1.13, 22.5) more likely to develop premenopausal breast cancer than those who weighed less than 3 kg (P-value for linear trend=0.03). This corresponded to an RR of 2.31 (0.95, 5.64) per 1 kg increase in birth weight. Birth weight was also a predictor of postnatal growth, that is, women who were heavy at birth remained taller and heavier throughout their childhood and young adulthood. However, the effect of birth weight on premenopausal breast cancer risk was only reduced slightly after simultaneous adjustment for height and body mass index (BMI) at age 2 years and height and BMI velocities throughout childhood and adolescence (adjusted RR=1.94 (0.74, 5.14) per 1 kg increase in birth weight). The pathways through which birth weight is associated with premenopausal breast cancer risk seem to be largely independent of those underlying the relation of postnatal growth to risk

Growth and Pubertal Development Among HIV Infected Children Aged 8-18 years in Dar es Salaam
No full textAdvances in management of HIV-infected infants and children have been remarkable, majority of infected children are now surviving into adolescence. Several studies have shown that growth and pubertal development is often impaired among children with HIV and AIDS. Abnormalities include early deficits in height and weight, and delay in skeletal maturation. Onset of menarche and pubertal development are also delayed. The magnitudes of delayed puberty among HIV infected children in Tanzania have not been studied; however there is one unpublished study, which evaluated the growth and pubertal development parameters in the general population. Assessment of the onset and progression of sexual maturation is important in patients with HIV because this information has immediate clinical application in the interpretation of endocrine and growth status. To assess growth and pubertal development among HIV infected children aged 8-18 in Dar es Salaam. This was a cross section hospital based study at Care and treatment clinics (CTC) municipal Hospitals in Dar es Salaam. After obtaining informed consent data was collected using a structured questionnaire. Anthropometric measurements of growth and Tanner stages of sexual development of children with HIV and AIDS aged between 8 and 18 years were assessed. Blood was taken to assess CD4 count. Both female and male were classified as having puberty when they are at Tanner stage 2 or greater for breast and genital respectively and pubic hair development in both sexes. Data was analyzed using STATA version 10 statistical packages. During the study period, 330 HIV infected children were recruited out of whom 183 (55.4 %) were female. The median age of the study populations was 12.0 years. Median weight was 32.0 (IQR 25-45) kg and girls were significantly heavier and had higher BMI than boys. All participants enrolled had HIV which was confirmed and were on ART. Median duration of ART was 48 (IQR 30-62) month. Majority of the participants were in WHO stage III and had CD4 count above 500cells/ul. HIV infected children were found in Tanner stage 2 at an advanced age compared to the reference population. The median age at menarche was 15 (IQR 14-16) years compared to the reference population, which was 13.0 (IQR 12-15) years. Among HIV infected females there was no significant difference in weight, height and BMI compared to the reference population when they entered Tanner stage 2. Males in the reference population were in Tanner stage 2 with higher weight and BMI and they were taller compared with the reference population. In univariable and multivariable analysis advanced age was associated with onset of Tanner stage 2 or more. Children infected with HIV and AIDS have significant delay in growth and sexual maturation. Considering these findings monitoring of growth and pubertal development should be highly emphasized in this population, it should be part of the comprehensive package. Matched case control studies of HIV-infected and uninfected children are needed to better quantify the delay in pubertal onset and to compare the pace of pubertal maturation
Full-field digital versus screen-film mammography: comparison within the UK breast screening program and systematic review of published data.
No full textPURPOSE: To (a) compare the performance of full-field digital mammography (FFDM), using hard-copy image reading, with that of screen-film mammography (SFM) within a UK screening program (screening once every 3 years) for women aged 50 years or older and (b) conduct a meta-analysis of published findings along with the UK data. MATERIALS AND METHODS: The study complied with the UK National Health Service Central Office for Research Ethics Committee guidelines; informed patient consent was not required, since analysis was carried out retrospectively after data anonymization. Between January 2006 and June 2007, a London population-based screening center performed 8478 FFDM and 31 720 SFM screening examinations, with modality determined by the type of machine available at the screening site. Logistic regression was used to assess whether breast cancer detection rates and recall rates differed between screening modalities. For the meta-analysis, random-effects models were used to combine study-specific estimates, if appropriate. RESULTS: A total of 263 breast cancers were detected. After adjustment for age, ethnicity, area of residence, and type of referral, there was no evidence of differences between FFDM and SFM in terms of detection rates (0.68 [95% confidence interval {CI}: 0.47, 0.89] vs 0.72 [95% CI: 0.58, 0.85], respectively, per 100 screening mammograms; P = .74), recall rates (3.2% [95% CI: 2.8, 3.6] vs 3.4% [95% CI: 3.1, 3.6]; P = .44), positive predictive value (PPV) of an abnormal mammogram, or characteristics of detected tumors. Meta-analysis of data from eight studies showed a slightly higher detection rate for FFDM, particularly at 60 years of age or younger (pooled FFDM-SFM difference: 0.11 [95% CI: 0.04, 0.18] per 100 screening mammograms), but no clear modality differences in recall rates or PPVs. CONCLUSION: Within a routine screening program, FFDM with hard-copy image reading performed as well as SFM in terms of process indicators; the meta-analysis was consistent with FFDM yielding detection rates at least as high as those for SFM
JM-20, a Benzodiazepine-Dihydropyridine Hybrid Molecule, Inhibits the Formation of Alpha-Synuclein-Aggregated Species
No full text\ua9 2022, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.Studies showed that JM-20, a benzodiazepine-dihydropyridine hybrid molecule, protects against rotenone and 6-hydroxydopamine neurotoxicity. However, its protective effects against cytotoxicity induced by endogenous neurotoxins involved in Parkinson’s disease (PD) pathogenesis have never been investigated. In this study, we evaluated the ability of JM-20 to inhibit alpha-synuclein (aSyn) aggregation. We also evaluated the interactions of JM-20 with aSyn by molecular docking and molecular dynamics and assessed the protective effect of JM-20 against aminochrome cytotoxicity. We demonstrated that JM-20 induced the formation of heterogeneous amyloid fibrils, which were innocuous to primary cultures of mesencephalic cells. Moreover, JM-20 reduced the average size of aSyn positive inclusions in H4 cells transfected with SynT wild-type and synphilin-1-V5, but not in HEK cells transfected with synphilin-1-GFP. In silico studies showed the interaction between JM-20 and the aSyn-binding site. Additionally, we showed that JM-20 protects SH-SY5Y cells against aminochrome cytotoxicity. These results reinforce the potential of JM-20 as a neuroprotective compound for PD and suggest aSyn as a molecular target for JM-20

Abstract
Infertility due to the inability of the uterus to carry a pregnancy ranks among the most unresolved issues in reproductive medicine. It affects millions of women worldwide who have congenital or acquired uterine affections, often requiring hysterectomy, and potentially represents a considerable fraction of the general infertile population. Patients suffering from severe uterine infertility are currently compelled to go through gestational surrogacy or adoption; both approaches, unfortunately, deprive them of the maternal experience of pregnancy and birth. Uterine transplantation represents an outstanding, yet complex, perspective to alleviating definitive uterine infertility. In the past decades, a number of scientific experiments conducted both in animals and women, focusing on uterine transplantation, have led to promising results. Collectively, these findings undoubtedly constitute a sound basis to clinically apply uterine transplantation in the near future. This paper is, however, an overview not only of the extent and limitations of accumulated scientific knowledge on uterine transplantation, but also its ethical implications, in an effort to define the actual place of such an approach among the therapeutic arsenal for alleviating infertility.

Translation and interpretation: Translation redundancy reconsidered
No full textInterpretation is an integral part of the process of translating. This article raises the question of whether interpretation fo a literary work by a translator should be guided by extratextual factors or not. The discussion is illustrated with examples taken from David Hawkes' translation of a Chinese classic, A Dream of Red Mansions. As the work of a scholar-translator, Hawkes' version is richly supplemented with disclosures concerning the characters and explanations of the cultural environment embodied in the novel. In many cases, however, this translation procedure is redundant and explanatory, enlightening the readers but at the same time robbing them of the pleasure of literary interpretation and cultural exploration. By means of this illustration of translation redundancy, the author points out that there is difference between a scholar who helps the interpretation fo a work and a translator who presents a work close to its original version. It is particularly important to pay attention tot his difference in literary translations in a cross-cultural situation involving two enormously different cultures.Language & LinguisticsA&HCI0ARTICLE1,SI115-12
