PURPOSE: Nationwide data have been lacking on drug abuse (DA)-associated mortality. We do not know the degree to which this excess mortality results from the characteristics of drug-abusing individuals or from the effects of DA itself. METHOD: DA was assessed from medical, criminal, and prescribed drug registries. Relative pairs discordant for DA were obtained from the Multi-Generation and Twin Registers. Mortality was obtained from the Swedish Mortality registry...

With new surgical techniques, more and more complex congenital heart defects are treated requiring sometimes right ventricle to pulmonary artery conduit implantation. In order to extend RV to PA conduit lifespan, 15 years ago a valved stent was developed. The implantation technique was progressively standardized to decrease risks of procedural complications. Medium and long-term hemodynamic results of the stent were so good that indications were broadened to native or complex right ventricular outflow tracts...

A questionnaire survey and interviews were conducted in households and end-of-life (EoL) mobile phone business centres in Hong Kong. Widespread Internet use, combined with the rapid evolution of modern social networks, has resulted in the more rapid obsolescence of mobile phones, and thus a tremendous increase in the number of obsolete phones. In 2013, the volume of EoL mobile phones generated in Hong Kong totalled at least 330 tonnes, and the amount is rising. Approximately 80% of electronic waste is exported to Africa and developing countries such as mainland China or Pakistan for recycling...

Disorders (differences) of sex development (DSD) are identified when there is atypical chromosomal, gonadal, or anatomic sex. Given the complexity of DSD conditions, the consensus guidelines recommend that affected individuals be evaluated and cared for by teams with expertise in DSD conditions. Obstetrician gynecologists are experts in genital and reproductive anatomy, hormonal function, fertility, sexuality, and obstetrics, allowing them to provide a unique and essential function within the DSD team. Furthermore, obstetrician gynecologists with expertise in Pediatric and Adolescent Gynecology may follow individuals from birth into adulthood and provide reproductive health care for all ages, allowing these patients to "grow up" with them...

The AMP-activated protein kinase (AMPK) is a heterotrimeric protein complex that is an important sensor of cellular energy status. Reduced expression of the AMPK β1 isoform has been linked to reduced survival in different cancers but whether this accelerates tumor progression and the potential mechanism mediating these effects is not known. Further, it is unknown whether AMPK β1 is implicated in tumorigenesis and if so what tissues may be most sensitive. In the current study we find that in the absence of the tumor suppressor p53, germline genetic deletion of AMPK β1 accelerates the appearance of a T cell lymphoma that reduces lifespan compared to p53 deficiency alone...

Although age-related ovarian failure in female mammals cannot be reversed, recent strategies have focused on improving reproductive capacity with age, and rapamycin is one such intervention that has shown a potential for preserving the ovarian follicle pool and preventing premature ovarian failure. However, the application is limited because of its detrimental effects on follicular development and ovulation during long-term treatment. Herein, we shortened the rapamycin administration to 2 weeks and applied the protocol to both young (8 weeks) and middle-aged (8 months) mouse models...

Previous studies have suggested that enhancer zeste homolog 2 (Ezh2), a histone methyltransferase subunit of polycomb repressive complex 2 (PRC2), acts as an oncogene in lung adenocarcinoma (ADC) development. However, we found that in human lung ADC samples, deletion and mutations of EZH2 were also frequently present, with 14% of patients harboring loss-of-function EZH2 alterations. To explore the effect of Ezh2 loss on lung tumor formation, lung epithelial Ezh2 gene was deleted in Kras-driven lung ADC mouse model...

BACKGROUND: The gene that encodes tumor protein p53, Tp53, is mutated or silenced in most human cancers and is recognized as one of the most important cancer drivers. Homozygotic Tp53 knockout mice, which develop lethal cancers early in their lives, are already used in cancer prevention studies, and now Tp53 knockout rats have also been generated. This study assessed feasibility of using homozygous Tp53 knockout rats to evaluate the possible outcome of cancer chemoprevention. METHODS: A small colony of Tp53 knockout rats with a Wistar strain genetic background was initiated and maintained in the animal house at our institution...

Globally, more than 20% of women of reproductive age are currently estimated to be obese. Children born to obese mothers are at higher risk of developing obesity, coronary heart disease, diabetes, stroke, and asthma in adulthood. Increasing clinical and experimental evidence suggests that maternal obesity also affects the health and function of the offspring brain across the lifespan. This review summarizes the current findings from human and animal studies that detail the impact of maternal obesity on aspects of learning, memory, motivation, affective disorders, attention-deficit hyperactivity disorder, autism spectrum disorders, and neurodegeneration in the offspring...

Selective eating (often referred to as "picky" eating) is common in individuals with autism spectrum disorder (ASD) across the lifespan. Behavioral interventions are widely used to treat selective eating; however, most of these programs are time intensive, have not been evaluated for use in outpatient settings, and do not typically include youth beyond early childhood. Despite the functional impact and risk for negative outcomes associated with selective eating, there are no empirically supported treatments available for older children, adolescents, or adults, either with or without ASD...

In the inquiry on the age related dietary assessment of an organism, knowledge of the distributional patterns of food intake throughout the entire life span is very important, however, age related nutritional studies often lack robust feeding quantification methods due to their limitations in obtaining short-term food-intake measurements. In this study, we developed and standardized a capillary method allowing precise life-time measurements of food consumption by individual adult medflies, Ceratitis capitata (Diptera: Tephritidae), under laboratory conditions...

Substance use disorders (i.e., drug addiction) constitute a global and insidious public health issue. Preclinical biomedical research has been invaluable in elucidating the environmental, biological, and pharmacological determinants of drug abuse and in the process of developing innovative pharmacological and behavioral treatment strategies. For more than 70 years, nonhuman primates have been utilized as research subjects in biomedical research related to drug addiction. There are already several excellent published reviews highlighting species differences in both pharmacodynamics and pharmacokinetics between rodents and nonhuman primates in preclinical substance abuse research...

Combined antiretroviral therapy (cART) has been successful in prolonging lifespan and reducing mortality of patients infected with human immunodeficiency virus (HIV). However, the eradication of latent HIV reservoirs remains a challenge for curing HIV infection (HIV cure) because of HIV latency in primary memory CD4(+) T cells. Currently, two types of HIV cures are in development: a "sterilizing cure" and a "functional cure." A sterilizing cure refers to the complete elimination of replication-competent proviruses in the body, while a functional cure refers to the long-term control of HIV replication without treatment...

BACKGROUND: This paper addresses the need for a paradigm shift from post-diagnosis tertiary care towards maintenance and promotion of health across the lifespan, for healthcare in general and in occupational healthcare specifically. It is based on the assumption that the realization of this paradigm shift may be facilitated by teaching (future) occupational health professionals to use the International Classification of Functioning, Disability and Health (ICF). OBJECTIVE: Describing the development of a an ICF based occupational health curriculum...

Sirtuins are nicotinamide adenine dinucleotide dependent class III histone deacetylase proteins that play a crucial role in several cellular processes, including DNA repair, apoptosis, and lifespan. Previous studies have shown that sirtuin inhibition leads to embryonic developmental arrest and oxidative stress in porcine and murine. However, sirtuin-mediated mechanisms have not been examined in porcine preimplantation blastocysts. We therefore investigated the relationship between sirtuins and autophagy. Embryos were cultured with 100 μM sirtinol (SIRT1/2 inhibitor) in NCSU-23 media after in vitro fertilization...

BACKGROUND: Patients with Eisenmenger syndrome have a shorter lifespan than the general population. A significant proportion develop arrhythmia and some, sudden death. OBJECTIVE: The aims of this study were to characterize the frequency, type and effects of arrhythmias in adult patients with Eisenmenger's syndrome and to identify risk factors for arrhythmias. METHODS: This retrospective study included patients aged ≥ 18 years of age with Eisenmenger's syndrome from three institutions...

Cri du Chat syndrome (CdC) is a chromosomal abnormality (deletion of short arm of chromosome 5) associated with intellectual disability and typical anatomical abnormalities. Research up to now focuses on the management of the disease during childhood. The longer lifespan of these patients warrants deeper investigations of how and if aging could be affected by the syndrome. We decided to focus on the association of the disease with proliferative disorders. Data on proliferative disorders in a cohort of 321 patients from Italian and German Cri du Chat databases were collected...

Brain size of vertebrates has long been recognized to evolve in close association with basic life-history traits, including lifespan. According to the cognitive buffer hypothesis, large brains facilitate the construction of behavioral responses against novel socioecological challenges through general cognitive processes, which should reduce mortality and increase lifespan. While the occurrence of brain size-lifespan correlation has been well documented in mammals, much less evidence exists for a robust link between brain size and longevity in birds...

The existence of small-molecule signals that influence development in Caenorhabditis elegans has been known for several decades, but only in recent years have the chemical structures of several of these signals been established. The identification of these signals has enabled connections to be made between these small molecules and fundamental signaling pathways in C. elegans that influence not only development but also metabolism, fertility, and lifespan. Spurred by these important discoveries and aided by recent advances in comparative metabolomics and NMR spectroscopy, the field of nematode chemistry has the potential to expand dramatically in the coming years...

OBJECTIVE: A precise and comprehensive description of personality continuity and change across the lifespan is the bedrock upon which theories of personality development are built. Little research has quantified the degree to which individuals deviate from mean-level developmental trends. In this study, we addressed this gap by examining individual differences in personality trait change across the life span. METHOD: Data came from a nationally representative sample of 9,636 Dutch participants who provided Big Five self-reports at five assessment waves across 7 years...
