More couples worldwide, delay their childbearing years. The increase in age causes a gradual decrease in female ovarian function and fertility, leading to an exponential decrease in women over 35 years of age having children. Although promising for some, assisted reproductive technology (ART) is not promising for older women. Decreased fertility in advanced age has become a growing concern in the field of reproduction. In this study, high-throughput transcriptome sequencing was used to identify the differentially expressed genes (DEGs) in the ovarian granulosa cells (GCs) of older women (aged 35-44) with infertility and younger women (aged 25-34). ATN161 The enriched functions and signaling pathways of DEGs were analyzed using Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG). The function of DEGs were analyzed and predicted combined with clinical ART data. Sequencing results were verified by quantitative reverse transcription-polymerase chain reaction. Retrospective clinical data and bioinformatics analyses revealed marked reductions in the retrieved oocyte, metaphase II oocyte, 2PN fertilization, and effective embryo numbers in older women. Although the clinical pregnancy and live birth rates did not differ notably between the groups, the miscarriage rate increased significantly in older women. In total, 620 DEGs were identified, of which 246 were upregulated, and 374 were downregulated in the older group. GO, and KEGG analyses indicated that the mechanism of fertility decline in older women was probably related to chronic inflammation, cytokine receptor interaction, and oxidative stress. In conclusion, combined with basic clinical ART data and pregnancy outcomes, we tried to provide a more intuitive and in-depth understanding of age-related reduction in ovarian function and pathogenesis of infertility with regard to chronic inflammation and oxidative stress.
Intestinal volvulus can cause morbidity and mortality. Surgical reduction, on the other hand, could result in ischemia-reperfusion (I/R) injury. Hydrogen rich saline solution (HRSS neutralizes free radicals in the body. This study aimed to investigate the effects of HRSS in I/R injury in experimental intestinal volvulus in rats.

Thirty rats were randomly allocated into 5 groups. All procedures were done under general anesthesia and sterile conditions in each animal. Five ml/kg of saline and HRSS were administered intraperitoneally (ip) in Sham (Group 1) and HRSS (Group 2) groups, respectively. Groups 3, 4, and 5 constituted the study groups in which volvulus was created in a 5-cm- long ileal segment 2 cm proximal to the ileocecal valve. After 2 hours the volvuli were reduced and following 2 hours of reperfusion, these segments were removed. In volvulus-I/R group (Group 3) no additional procedure was done. HRSS was administered shortly before reperfusion (reduction of the volvulus) in Treatment I (Group 4) and 1 h before experimental volvulus in Treatment II (Group 5) groups. Blood and intestinal tissue samples were obtained from all rats at the 4th hour. Both tissue and blood total oxidant (TOS) and antioxidant status (TAS) levels were determined and tissue histomorphologies were studied. Oxidative stress indices (TOS ÷ TAS) (OSI) were calculated.

Tissue TOS and OSI levels and histomorphological injury scores were statistically lower in treatment groups than I/R group, whereas blood TOS and OSI levels were similar between the groups.

This study provides biochemical and histomorphological evidence that HRSS prevents intestinal damage in I/R injury caused by volvulus.

It is rarely seen in cytological smears, exfoliative scrapings or in effusions. We present the case of a 29-year old female with filaria found on cytological examination of both breast and ovary.In the introduction to the special issue, Greco and Graber discuss the concept of chronicity and the ways it is used in the contributions to the special issue. Historians have shown that the concept of chronic disease has its origins in policy and has always been fluid and vague; however, the classic literature in sociology and nursing has focused on modelling the evolution of chronic disease rather than on examining the concept itself. In the introduction, chronicity is explored in the ways in which it is transformed by medical innovation. Innovations in biomedicine promise to turn terminal and acute conditions in chronic and to render chronic conditions curable. Even when such promises are not fulfilled, they change the context of the illness and the experiences of patients. In such a context a specific work is required from patients, in terms of adherence to the treatments, but also in terms of pursuing experimental treatments that could make their condition chronic. The introduction offers a critical exploration of the concept of chronicity, highlighting both its fluid definition and the changes linked to medical innovation, and the ways in which it shapes the temporalities and experiences of illness in complex ways that cannot be reduced to simplified schemas and trajectories.The present report investigated whether nonmusicians can incidentally learn musical skills needed for sight-reading. On each trial, participants identified a note name written inside of a note on the musical staff. In Experiment 1, each note was presented frequently with the congruent note name (e.g., "do" with the note for "do") and rarely with the incongruent names (e.g., "do" with the note for "fa"). With or without deliberate learning instructions, a robust contingency learning effect was observed faster responses for congruent trials compared with incongruent trials. Participants also explicitly identified the meaning of the note positions more accurately than chance. Experiment 2 ruled out the potential influence of preexisting knowledge on the contingency learning effect by presenting notes most often with an incongruent note name. Robust learning was again observed, suggesting that participants acquired sufficient knowledge of musical notation to produce automatic influences on behaviour (e.g., akin to the interference effect previously found in skilled musicians). A congruency effect was additionally observed in Experiment 2, however. Experiment 3 further explored to what extent this congruency effect might be due to prior music knowledge and/or spatial stimulus-response compatibility between note and response locations (analogous to the SMARC effect). Overall, our results open up new avenues for investigating the incidental learning of complex material, musical or otherwise, and for reinforcing learning even further.
We developed a multi-resolution foveated laparoscope (MRFL) to improve situational awareness in laparoscopic surgery. We assessed surgeon objective task performance and subjective attitudes with MRFL when used for box trainer tasks and porcine surgery.

The MRFL simultaneously obtains a wide-angle view and a magnified view. The 2 images are displayed simultaneously. 6 urologists and 2 general surgeons performed box trainer and porcine surgery tasks with the MRFL and a standard laparoscope. Task time, use of display options, and subjective assessments were obtained.

Subjectively, surgeons rated situational awareness, depth perception, and instrument interference as comparable between the prototype MRFL and laparoscope for trainer tasks. For porcine surgery, the MRFL was rated as having less interference than the standard laparoscope. The image quality of the MRFL was rated interior to the standard laparoscope. Participants found the different viewing modes useful for different roles and reported that they would likely use the MRFL for conventional laparoscopic and robotic surgery. Objectively, box trainer task time was comparable for 2 of 3 tasks with the remaining task shorter for the standard laparoscope. Porcine nephrectomy and oophorectomy were feasible with the prototype MRFL, although nephrectomy task time was significantly longer than traditional laparoscopy.

The MRFL demonstrated feasibility for performing complex surgery. Surgeons had favorable attitudes toward its features and likelihood to use the device if available. Users utilized different view types for different tasks. Longer MRFL task times were attributed to poorer image quality of the prototype.

There are substantial differences in remaining life expectancy at higher ages between occupational groups. These differences may be the effect of work-related exposures, lifestyle factors of workers in specific occupations, socioeconomic position or a combination of this. The scope of this paper is the extent to which occupational differences in remaining life expectancy persist after retirement, which would suggest that occupational exposures alone are not likely to explain all the difference.

All individuals born between 1925 and 1939 who reported occupational information in the Census 1985 and were residents in Sweden to the end of 2020 or who died were included and followed for death until 2020. The Nordic Classification of Occupations was used to create nine occupational groups. Partial life expectancy and age-specific death rates were applied to examine mortality differentials.

This study showed substantial differences in partial life expectancy across the occupational cohorts with the biggest difference being about 2 years. The mortality differences persisted with increasing age, both when measured as absolute numbers as well as relative numbers.


The lack of convergence in mortality at high ages suggests that factors associated with lifestyle may play a larger role than occupational factors for the mortality differences between occupational groups at high ages. However, it cannot be ruled out that long-lasting effects of earlier occupational exposures also contribute. Regardless of the exact mechanism, we conclude that there is room for further reduction in mortality at high ages and, thus, for further improvement in life expectancy.
Our sexual health services (SHS) introduced routine domestic abuse (DA) enquiry in April 2018 following targeted staff training. A survey was undertaken to ascertain attitudes towards the initiative.

Between October 2019 and March 2020, patients were invited to respond to an anonymous questionnaire by SMS. Clinical staff were emailed a separate survey.

The patient response rate was 40% (226/562) 72% (161/226) female, 80% (179/226) heterosexual, 19% (42) LGBT, 47% (106) aged 25-34 and 25% (57) aged 18-24. Almost all (97%, 220) recalled routine enquiry at their clinic appointment; 91% (206) felt comfortable when asked, and 95% (214) found this acceptable. Fifty-one staff responded (36% response rate), 67% (34) female, 55% (28) heterosexual, 35% (18) LGBT. 43% (22) were nurses, 31% (16) doctors, 12% (6) health advisers and 8% (4) healthcare assistants. The majority of staff 96% (49) were confident with conducting routine enquiry, 92% (47) agreed patients found it acceptable; 92% (47) felt routine enquiry was appropriate and 92% (47) had received targeted training.
