A systematic review of interventions to improve male knowledge of fertility and fertility-related risk factors.

Male infertility is a global health concern. The effectiveness of interventions developed to improve males' knowledge of fertility regulation and fertility-related risk factors remains unclear. This systematic review aimed to synthesize and evaluate the evidence for these interventions.

Women's views on content and delivery methods for interventions to improve preconception health: a qualitative exploration.

Background: Systematic review evidence suggests preconception health interventions may be effective in improving a range of outcomes. However, few studies have explored women's views on potential content and delivery methods for these interventions.

Methods: Participants were purposively sampled from respondents ( = 313) of a survey.

The Challenge of Weight Stigma for Women in the Preconception Period: Workshop Recommendations for Action from the 5th European Conference on Preconception Health and Care.

Weight stigma is a well-recognised public health issue affecting many members of society including women during the preconception period. The impacts of preconception weight stigma on women are significant and may result in decreased access to and uptake of healthcare, and mental health concerns. The consequences of this weight stigma may translate to negative maternal outcomes and even intergenerational effects on the child.

Women's knowledge, attitudes and views of preconception health and intervention delivery methods: a cross-sectional survey.

Background: Several preconception exposures have been associated with adverse pregnancy, birth and postpartum outcomes. However, few studies have investigated women's knowledge of and attitudes towards preconception health, and the acceptability of potential intervention methods.

Methods: Seven primary care centres in the West of England posted questionnaires to 4330 female patients aged 18 to 48 years.

Difficult but necessary conversations--the case for advance care planning.

Many patients at the end of life receive care that is inappropriate or futile and, if given the opportunity to discuss their care preferences well ahead of death, may well have chosen to forgo such care. Advance care planning (ACP) is a process of making decisions about future health care for patients in consultation with clinicians, family members and important others, and to safeguard such decisions if patients were to lose decisional capacity. Although ACP has existed as an idea for decades, acceptance and operationalisation of ACP within routine practice has been slow, despite evidence of its benefits.

Substrate-induced control of product formation by protein arginine methyltransferase 1.

Protein arginine methyltransferases (PRMTs) aid in the regulation of many biological processes. Accurate control of PRMT activity includes recognition of specific arginyl groups within targeted proteins and the generation of the correct level of methylation, none of which are fully understood. The predominant PRMT in vivo, PRMT1, has wide substrate specificity and is capable of both mono- and dimethylation, which can induce distinct biological outputs.

The Bundaberg emergency response team.

A major crisis affected Bundaberg Hospital in 2005 following the exposure of the concerns about Dr Jayant Patel and the subsequent sudden exit of the Hospital Executive. The Bundaberg Emergency Response Team (BERT) was created as an emergency intervention whose brief was, over a 6-week period, to maintain the function of the hospital in the face of the community's loss of confidence in the service; to find out what had happened to Dr Patel's patients and to organise appropriate care and treatment for them. The authors acted as the senior members of BERT.

Effects of select anions from the Hofmeister series on the gas-phase conformations of protein ions measured with traveling-wave ion mobility spectrometry/mass spectrometry.

The gas-phase conformations of ubiquitin, cytochrome c, lysozyme, and α-lactalbumin ions, formed by electrospray ionization (ESI) from aqueous solutions containing 5 mM ammonium perchlorate, ammonium iodide, ammonium sulfate, ammonium chloride, ammonium thiocyanate, or guanidinium chloride, are examined using traveling-wave ion mobility spectrometry (TWIMS) coupled to time-of-flight (TOF) mass spectrometry (MS). For ubiquitin, cytochrome c, and α-lactalbumin, adduction of multiple acid molecules results in no significant conformational changes to the highest and lowest charge states formed from aqueous solutions, whereas the intermediate charge states become more compact. The transition to more compact conformers for the intermediate charge states occurs with fewer bound H(2)SO(4) molecules than HClO(4) or HI molecules, suggesting ion-ion or salt-bridge interactions are stabilizing more compact forms of the gaseous protein.

Investigation of the molecular origins of protein-arginine methyltransferase I (PRMT1) product specificity reveals a role for two conserved methionine residues.

Protein-arginine methyltransferases aid in the regulation of many biological processes by methylating specific arginyl groups within targeted proteins. The varied nature of the response to methylation is due in part to the diverse product specificity displayed by the protein-arginine methyltransferases. In addition to site location within a protein, biological response is also determined by the degree (mono-/dimethylation) and type of arginine dimethylation (asymmetric/symmetric).

Effects of supercharging reagents on noncovalent complex structure in electrospray ionization from aqueous solutions.

The effects of two supercharging reagents, m-nitrobenzyl alcohol (m-NBA) and sulfolane, on the charge-state distributions and conformations of myoglobin ions formed by electrospray ionization were investigated. Addition of 0.4% m-NBA to aqueous ammonium acetate solutions of myoglobin results in an increase in the maximum charge state from 9+ to 19+, and an increase in the average charge state from 7.

The influence of patient centering on CT dose and image noise.

Although x-ray intensity shaping filters (bowtie filters) have been used since the introduction of some of the earliest CT scanner models, the clinical implications on dose and noise are not well understood. To achieve the intended dose and noise advantage requires the patient to be centered in the scan field of view. In this study we explore the implications of patient centering in clinical practice.

Comparison of radiofrequency ablation in normal versus scarred myocardium.

Introduction: Reentrant circuits causing ventricular tachycardia are closely associated with previously scarred myocardium. The presence of scar has been blamed for the poor success rate of radiofrequency ablation (RFA) in that context. This article investigates the in vivo effects of radiofrequency ablation in myocardium scarred from acute myocardial infarction.
