A qualitative investigation of obese men\u27s experiences with their weight

Objectives: To investigate obese men\u27s health behaviors and strategies for change. Methods: Qualitative interviews with 36 men (BMI 30 and over). Results: All men felt personally responsible for their weight gain. Sedentary lifestyles, stress, lack of worklife balance and weight-based stigma were all significant causes of weight gain and barriers to weight loss. These factors also contributed to men\u27s unwillingness to seek help for their overweight. Conclusion: Addressing the self-blame and stigma associated with obesity is important in developing strategies to improve the health and well-being of obese men

The response to whistleblowing by regulators: a practical perspective

The Public Interest Disclosure Act 1998 provides protection for whistleblowers; it does not place statutory obligations on regulators to act in response to whistleblowing concerns. Using Freedom of Information requests as a research methodology, this paper seeks to examine how whistleblowing is approached by regulators and what happens when a whistleblowing disclosure is made. Forty-eight national regulators in a variety of fields and 408 county, district and unitary local authorities with responsibility for the regulation of food were contacted. The paper begins by considering the importance of whistleblowing disclosures and how they are protected in PIDA. The examination of the law reveals that several organisations with important regulatory functions are not prescribed, and this has the potential to create inconsistencies in the protection of whistleblowers. The bulk of the paper examines the results of the Freedom of Information requests. By examining the results of these requests, it was possible to show that there are a number of inconsistencies in the way in which regulatory agencies handle concerns. Several changes to practice are suggested in order to ensure that the whistleblowers receive appropriate treatment and that the concerns that they express can be properly addressed

Long Term outcomes of percutaneous atrial fibrillation ablation in patients with continuous monitoring

INTRODUCTION: There is limited data using continuous monitoring to assess outcomes of atrial fibrillation (AF) ablation. This study assessed long-term outcomes of AF ablation in patients with implantable cardiac devices. METHODS: 207 patients (mean age 68.1 ± 9.5, 50.3% men) undergoing ablation for symptomatic AF were followed up for a mean period of 924.5 ± 636.7 days. Techniques included The Pulmonary Vein Ablation Catheter (PVAC) (59.4%), cryoablation (17.4%), point by point (14.0%) and The Novel Irrigated Multipolar Radiofrequency Ablation Catheter (nMARQ) (9.2%). RESULTS: 130 (62.8%) patients had paroxysmal AF (PAF) and 77 (37.2%) persistent AF. First ablation and repeat ablation reduced AF burden significantly (relative risk 0.91, [95% CI 0.89 to 0.94]; P <0.0001 and 0.90, [95% CI, 0.86-0.94]; P <0.0001). Median AF burden in PAF patients reduced from 1.05% (interquartile range [IQR], 0.1%-8.70%) to 0.10% ([IQR], 0%-2.28%) at one year and this was maintained out to four-years. Persistent AF burden reduced from 99.9% ([IQR], 51.53%-100%) to 0.30% ([IQR], 0%-77.25%) at one year increasing to 87.3% ([IQR], 4.25%-100%) after four years. If a second ablation was required, point-by-point ablation achieved greater reduction in AF burden (relative risk, 0.77 [95% CI, 0.65-0.91]; P <0.01). CONCLUSION: Ablation reduces AF burden both acutely and in the long-term. If a second ablation was required the point-by-point technique achieved greater reductions in AF burden than "single-shot" technologies. Persistent AF burden increased to near pre ablation levels by year 4 suggesting a different mechanism from PAF patients where this increase did not occur

The role of violent thinking in violent behaviour; it’s more about thinking than drinking

This article aims to explore and report on violent thinking and alcohol misuse; how these factors may predict self-reported violence. The role of violent thinking in violent behavior is both well established in theoretical models, yet there are few measures that explain this role. One measure that has been identified is the Maudsley Violence Questionnaire (MVQ). This is the first study to explore the use of the MVQ with a general (nonoffender) adult sample, having already been shown to be valid with young people (under 18 years old), adult male offenders, and mentally disordered offenders. This study involved 808 adult participants—569 female and 239 male participants. As figures demonstrate that around half of all violent crime in the United Kingdom is alcohol related, we also explored the role of alcohol misuse. Regression was used to explore how these factors predicted violence. The results demonstrate the important role of violent thinking in violent behavior. The MVQ factor of “Machismo” was the primary factor in regression models for both male and female self-reported violence. The role of alcohol in the regression models differed slightly between the male and female participants, with alcohol misuse involved in male violence. The study supports theoretical models including the role of violent thinking and encourages those hoping to address violence, to consider “Machismo” as a treatment target. The study also provides further validation of the MVQ as a helpful tool for clinicians or researchers who may be interested in “measuring” violent thinking

Flexibility of KorA, a plasmid-encoded, global transcription regulator, in the presence and the absence of its operator

The IncP (Incompatibility group P) plasmids are important carriers in the spread of antibiotic resistance across Gram-negative bacteria. Gene expression in the IncP-1 plasmids is stringently controlled by a network of four global repressors, KorA, KorB, TrbA and KorC interacting cooperatively. Intriguingly, KorA and KorB can act as co-repressors at varying distances between their operators, even when they are moved to be on opposite sides of the DNA. KorA is a homodimer with the 101-amino acid subunits, folding into an N-terminal DNA-binding domain and a C-terminal dimerization domain. In this study, we have determined the structures of the free KorA repressor and two complexes each bound to a 20-bp palindromic DNA duplex containing its consensus operator sequence. Using a combination of X-ray crystallography, nuclear magnetic resonance spectroscopy, SAXS and molecular dynamics calculations, we show that the linker between the two domains is very flexible and the protein remains highly mobile in the presence of DNA. This flexibility allows the DNA-binding domains of the dimer to straddle the operator DNA on binding and is likely to be important in cooperative binding to KorB. Unexpectedly, the C-terminal domain of KorA is structurally similar to the dimerization domain of the tumour suppressor p53

Exposing Sgr tidal debris behind the Galactic disc with M giants selected in WISE∩2MASS

We show that a combination of infrared photometry from WISE and 2MASS surveys can yield highly pure samples of M giant stars. We take advantage of the new WISEn2MASS M giant selection to trace the Sagittarius (Sgr) trailing tail behind the Galactic disc in the direction of the anticentre. The M giant candidates selected via broad-band photometry are confirmed spectroscopically using AAOmega on the Anglo-Australian Telescope in three fields around the extremity of the Sgr trailing tail in the Southern Galactic hemisphere.We demonstrate that at the Sgr longitude (n-ary logical and) ⊙ = 204°, the line-of-sight velocities of the trailing tail starts to deviate from the track of the Law & Majewski model, confirming the prediction of Belokurov et al. This discovery serves to substantiate the measurement of low differential orbital precession of the Sgr stream which in turn may imply diminished dark matter content within 100 kpc
