Abstract

Civic engagement is a classic example of a collective action problem: while civic participation improves life in the community as a whole, it is individually costly and thus there is an incentive to free ride on the actions of others. Yet, we observe significant inter-individual variation in the degree to which people are in fact civically engaged. Early accounts reconciling the theoretical prediction with empirical reality focused either on variation in individuals' material resources or their attitudes, but recent work has turned to genetic differences between individuals. We show an underlying genetic contribution to an index of civic engagement (0.41), as well as for the individual acts of engagement of volunteering for community or public service activities (0.33), regularly contributing to charitable causes (0.28) and voting in elections (0.27). There are closer genetic relationships between donating and the other two activities; volunteering and voting are not genetically correlated. Further, we show that most of the correlation between civic engagement and both positive emotionality and verbal IQ can be attributed to genes that affect both traits. These results enrich our understanding of the way in which genetic variation may influence the wide range of collective action problems that individuals face in modern community life.

Abstract

Interleukin-8 (IL-8) has been implicated in the pathogenesis of several human respiratory diseases, including tuberculosis (TB). Importantly and in direct relevance to the objectives of this report quite a few findings suggest that the presence of IL-8 may be beneficial for the host. IL-8 may aid with mounting an adequate response during infection with Mycobacterium tuberculosis (M. tb); however, the underlying mechanism remains largely unknown. The major goal of our study was to investigate the contribution of IL-8 to the inflammatory processes that are typically elicited in patients with TB. We have shown for the first time that IL-8 can directly bind to tubercle bacilli. We have also demonstrated that association of IL-8 with M. tb molecules leads to the augmentation of the ability of leukocytes (neutrophils and macrophages) to phagocyte and kill these bacilli. In addition, we have shown that significant amount of IL-8 present in the blood of TB patients associates with erythrocytes. Finally, we have noted that IL-8 is the major chemokine responsible for recruiting T lymphocytes (CD3(+), CD4(+), and CD8(+) T cells). In summary, our data suggest that the association of IL-8 with M. tb molecules may modify and possibly enhance the innate immune response in patients with TB.

Abstract

BACKGROUND:

It has been anticipated that physician and parents will be ill prepared or unprepared for the clinical introduction of genome sequencing, making it ethically disruptive.

PROCEDURE:

As a part of the Baylor Advancing Sequencing in Childhood Cancer Care study, we conducted semistructured interviews with 16 pediatric oncologists and 40 parents of pediatric patients with cancer prior to the return of sequencing results. We elicited expectations and attitudes concerning the impact of sequencing on clinical decision making, clinical utility, and treatment expectations from both groups. Using accepted methods of qualitative research to analyze interview transcripts, we completed a thematic analysis to provide inductive insights into their views of sequencing.

RESULTS:

Our major findings reveal that neither pediatric oncologists nor parents anticipate sequencing to be an ethically disruptive technology, because they expect to be prepared to integrate sequencing results into their existing approaches to learning and using new clinical information for care. Pediatric oncologists do not expect sequencing results to be more complex than other diagnostic information and plan simply to incorporate these data into their evidence-based approach to clinical practice, although they were concerned about impact on parents. For parents, there is an urgency to protect their child's health and in this context they expect genomic information to better prepare them to participate in decisions about their child's care.

CONCLUSIONS:

Our data do not support the concern that introducing genome sequencing into childhood cancer care will be ethically disruptive, that is, leave physicians or parents ill prepared or unprepared to make responsible decisions about patient care.

Abstract

Religious beliefs and cultures have influenced treatment of dead bodies in different ways by nations throughout history, and attitudes toward the deceased individuals have changed across time and so has the role and mechanism of autopsy. Islam has been a part of Europe for a long time; therefore, we would like to emphasize the important issues for Muslims and their families regarding death, autopsy, and funeral and to describe international perspectives of Muslim autopsies. Muslims have expressed their views on autopsy publically and internationally, and there have been claims of violation of the deceased, delays in burial, and nonconsideration of their religious beliefs. In this article, we aim to increase awareness and understanding of doctors about the religious and ethical issues important to Muslims and their families, so that appropriate considerations may be made where possible with regard to respectful treatment of deceased loved ones to decrease tensions presently being faced. Forensic medicine doctors could assist by undertaking autopsy without delay, in a private room by those of the same sex, and covering parts of the body not being worked on at that time.

Abstract

BACKGROUND:

In 2013, Angelina Jolie's double mastectomy and publication of her personal treatment choice for BRCA1 positivity generated considerable media attention. To the authors' knowledge, the current study is the first prospective survey conducted among the general public to measure a quantifiable media-related effect on public awareness.

METHODS:

The authors analyzed the changes in the general public's awareness of reconstructive options in breast cancer among 2 female population-matched cohorts aged 18 to 65 years (1000 participants in each cohort) before (March 2013; poll 1) and after (June 2013; poll 2) the announcement of Ms. Jolie's mastectomy in May 2013.

RESULTS:

There was an observed increase in public awareness: significantly more women from poll 2 were aware of reconstructive breast surgery being possible after breast cancer-related mastectomy, notably with regard to autologous tissue and single-stage reconstructions. Approximately 20% of the women in poll 2 (205 women) indicated that media coverage regarding Ms. Jolie affected their interest in breast cancer. A question that was exclusive to poll 2 revealed a preference for autologous (66.2%) versus implant-based (8.2%) reconstructions, with the remainder indicating no preference (25.6%). None of the stratification variables were found to be associated with the above findings.

CONCLUSIONS:

To the best of the authors' knowledge, this is the first prospective study to demonstrate a statistically significant impact of a celebrity announcement on public awareness regarding breast cancer treatment. The results underscore the importance of a media-related impact for professionals in the health care sector, which can serve as a tipping point for raising awareness and improving knowledge concerning a specific disease among the general public.

The “Angelina Jolie effect”: "...the number of women referred for genetic counseling skyrocketed..."

Angelina Jolie has highlighted the benefits of genetic testing and surgery to prevent hereditary breast cancer, but women must also consider the risks.
ARLENE WEINTRAUB











"Genetic testing is on the rise among women who believe they are at high risk for breast cancer — a trend that has been dubbed the “Angelina Jolie effect” because it occurred after the actress’s public disclosure of her BRCA status and her decision to remove her breasts, which was followed two years later by the elective removal of her ovaries and fallopian tubes. A retrospective study performed at a Toronto hospital in 2014, for example, reported that the number of women referred for genetic counseling skyrocketed by 90 percent in the six months after Jolie’s announcement. The number of women at the hospital identified as BRCA1 or BRCA2 mutation carriers during that period jumped by 110 percent."

Precautions needed for flu season



Precautions needed for flu season


"'The biggest thing to do to prevent contracting or transmission of flu is to get the flu vaccination, as well as washing hands with an alcohol-based sanitizer, not coughing or sneezing on others and staying away from people you know are sick,” he said. “Also, it is a misconception that the flu shot can cause the flu. Getting the flu shot is important protection for you and your entire family.'

Although the shot is recommended for everyone over the age of six months, according to Seymour it is especially important for people in specific populations. This includes children six months through four years old, adults age 50 or older and people with long-term health problems such as asthma, lung problems, heart disease, diabetes or severe obesity."

Notion Obese Fare Better vs. Chronic Ills Refuted

Prior research suggesting that excess weight may offer protection called flawed

By Dennis Thompson
HealthDay Reporter
"People who are seriously ill tend to lose weight as they near death, the study authors explained. And that fact influences the data enough to create the false perception of an obesity paradox, argued lead author Samuel Preston, a professor of sociology at the University of Pennsylvania in Philadelphia".

Abstract

BACKGROUND:

Worldwide, thousands of children are acting in different roles in armed groups. Whereas human rights activism and humanitarian imperatives tend to emphasize the image of child soldiers as incapable victims of adults' abusive compulsion, this image does not fully correspond with prevailing pedagogical and jurisprudential discourses, nor does it represent all child soldiers' own perceptions of their role. Moreover, contemporary warfare is often marked by fuzzy distinctions between perpetrators and victims. This article deepens on the question how to conceptualize the victim-perpetrator imaginary about child soldiers, starting from three disciplines, children's rights law, psychosocial approaches and transitional justice, and then proceeding into an interdisciplinary approach.

DISCUSSION:

We argue that the victim-perpetrator dichotomy in relation to child soldiers needs to be revisited, and that this can only be done successfully through a truly interdisciplinary approach. Key to this interdisciplinary dialogue is the growing awareness within all three disciplines, but admittedly only marginally within children's rights law, that only by moving beyond the binary distinction between victim- and perpetrator-hood, the complexity of childhood soldiering can be grasped. In transitional justice, the concept of role reversal has been instructive, and in psychosocial studies, emphasis has been put on the 'agency' of (former) child soldiers, whereby child soldiers sometimes account on how joining the armed force or group was (partially) out of their own free will. Hence, child soldiers' perpetrator-hood is not only part of the way child soldiers are perceived in the communities they return to, but equally of the way they see themselves. These findings plea for more contextualized approaches, including a greater participation of child soldiers, the elaboration of accountability mechanisms beyond criminal responsibility, and an intimate connection between individual, social and societal healing by paying more attention to reconciliation. This article deepens on the question how to conceptualize the victim-perpetrator imaginary about child soldiers through an interdisciplinary dialogue between children's rights law, psychosocial approaches and transitional justice. With this interdisciplinary perspective, we intend to open up narrow disciplinary viewpoints, and contribute to more integrated approaches, beyond a binary distinction between victimhood and perpetrator-hood.

Abstract

In non-small cell lung cancer (NSCLC), the first immune checkpoint inhibitor to be approved by the US Food and Drug Administration was nivolumab, based on a survival advantage over docetaxel in recurrent squamous NSCLC, a difficult-to-treat histology. In addition, several other immune checkpoint inhibitors are also in late-stage development. Most of these agents inhibit the programmed cell death protein 1 (PD-1) pathway, targeting either the PD-1 receptor or its ligand, programmed cell death ligand 1 (PD-L1). In addition to nivolumab, pembrolizumab is a PD-1 inhibitor under investigation in NSCLC, and atezolizumab (MPDL3280A), durvalumab (MEDI4736), and avelumab (MSB0010718C) are PD-L1 inhibitors under investigation. The cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) immune checkpoint inhibitors ipilimumab and tremelimumab are also under investigation in NSCLC, largely as part of combination approaches rather than as monotherapy. PD-L1 expression as a potential biomarker to select patients most likely to respond to inhibitors of the PD-1 pathway has been widely studied.

Abstract

Different approaches for treating lung cancer have been developed over time, including chemotherapy, radiotherapy and targeted therapies against activating mutations. Lately, better understanding of the role of the immunological system in tumor control has opened multiple doors to implement different strategies to enhance immune response against cancer cells. It is known that tumor cells elude immune response by several mechanisms. The development of monoclonal antibodies against the checkpoint inhibitor programmed cell death protein 1 (PD-1) and its ligand (PD-L1), on T cells, has led to high activity in cancer patients with long lasting responses. Nivolumab, an anti PD-1 inhibitor, has been recently approved for the treatment of squamous cell lung cancer patients, given the survival advantage demonstrated in a phase III trial. Pembrolizumab, another anti PD-1 antibody, has received FDA breakthrough therapy designation for treatment of non-small cell lung cancer(NSCLC), supported by data from a phase I trial. Clinical trials with anti PD-1/PD-L1 antibodies in NSCLC have demonstrated very good tolerability and activity, with response rates around 20% and a median duration of response of 18 months.

Out: Standing desks. In: Treadmill desks.

New Study Concludes That Standing Isn't Necessarily Healthier Than Sitting Down All Day


“The problem lies in the absence of movement rather than the time spent sitting itself,” Hillsdon said in a statement. “Any stationary posture where energy expenditure is low may be detrimental to health, be it sitting or standing. The results cast doubt on the benefits of sit-stand work stations.”
So what are we left with? It looks like treadmill desks may indeed be the way forward. Just please promise us that human-sized hamster wheelsaren’t actually going to become a thing anytime soon.

In Rememberance: James H. "Red" Duke, Jr, M.D. (from UTHealth and MemorialHermann)

JAMES H. "RED" DUKE, JR, M.D.

1928 - 2015

"With his undergraduate degree in hand, he served for two years as an Army tank commander in Germany during the Korean War before enrolling in the Southwestern Baptist Theological Seminary in Fort Worth.  He received a divinity degree in 1955.
During seminary, a book about Albert Schweitzer, M.D., inspired Duke to pursue a career in academic medicine. He thought that caring for patients and conducting scientific research while training the next generations of physicians would be the best ways he could serve his community."
