Many skin lightening preparations containing hydroquinone, kojic acid, arbutin, and deoxyarbutin are toxic to melanocytes.

This research examined a new skin lightening agent from a family of gem difluorocompounds 2-[2-(2,4-difluorophenyl)-2-propen-1-yl]-1,3-propanediol that also function as tyrosinase inhibitors. This ingredient does not exhibit melanocyte toxicity yet is capable of inducing skin lightening. This research compared the gem difluorocompound, TFC-1067, to hydroquinone evaluating both tolerability and efficacy for lightening facial dyschromia.

48 nonpregnant and non-nursing healthy female subjects age 25-70years skin types I-IV with mild-to-moderate facial dyschromia were randomized to receive either study product or 2% hydroquinone cream. Subject and investigator tolerability and efficacy assessments were made at baseline, week 4, week 8, and week 12. Dermaspectrophotometer readings from normal skin and a pigmented target area were obtained. All subjects underwent facial photography at each visit.

TFC-1067 and 2% hydroquinone produced statistically significant skin lightening after 8weeks of use, but only hydroquinone lightened the normal skin. This pattern continued into week 12 where both products significantly lightened dyschromic skin, but hydroquinone also lightened the normal skin, which is not always desirable.

Smoking is a major public health issue, and its effect on cardiovascular outcomes is well established. This study evaluates the impact of donor smoking on heart transplant (HT) outcomes.

HT recipients between January 1, 2005, and December 31, 2016, with known donor smoking status were queried from the International Society of Heart and Lung Transplantation (ISHLT) registry. The primary outcome was all-cause mortality, and secondary endpoints were graft failure, acute rejection, and cardiac allograft vasculopathy. We utilized propensity-score matching to identify cohorts of recipients with and without a history of donor smoking. Hazard ratios for post-transplant outcomes for the matched sample were estimated from separate Cox proportional hazard models.

Of 26390 patients in the cohort, 18.9% had history of donor smoking. Donors with history of smoking were older, predominantly male and had higher incidence of diabetes, hypertension, cocaine use, and "high-risk" status. In propensity-matched analysis, recipients with a history of donor smoking had increased risk of death (HR 1.11, 95% CI 1.03-1.20) and higher risk of graft failure (HR 1.11, 95% CI 1.03-1.20).

Donor smoking was associated with increased mortality and higher incidence of graft failure following HT. Consideration of donor smoking history is warranted while evaluating donor hearts.

This study aimed to test if a behavioural activation (BA) programme was more effective than usual care at reducing the risk of conversion to major depression over 52 weeks among adults aged 65 years or older living in rural Western Australia. Secondary aims were to test if participants assigned to the BA intervention experienced greater decline in the severity of depressive and anxiety symptoms than older adults treated with usual care over 26 and 52 weeks, as well as greater improvement in physical and mental health-related quality of life.

Randomised controlled clinical trial that started recruitment in February 2016 in rural Western Australia. We used the electoral roll to invite adults aged 65 years or over living in suitable regions of Western Australia to take part in the study. We recruited those who consented and screened positive to at least one of the two Whooley questions feeling down/depressed/hopeless or little interest or pleasure over the past month. Participants were randomly assigned to usignificant effects of the BA intervention, while complete-case analyses showed that participants treated with BA compared with usual care experienced significant improvements in depression and anxiety symptoms over 52 weeks, as well as improved mental health quality of life.

Few participants developed a major depressive episode during follow-up. The BA intervention was associated with improved symptoms of depression and anxiety, although the clinical significance of these benefits remains unclear.

To determine the risk of disease progression and conversion to active treatment following a negative biopsy while on active surveillance (AS) for prostate cancer (PCa).

Men on an AS programme at a single tertiary hospital (London, UK) between 2003 and 2018 with confirmed low-intermediate-risk PCa, Gleason Grade Group <3, clinical stage <T3 and a diagnostic prostate-specific antigen (PSA) level of <20ng/mL. This cohort included men diagnosed by transrectal ultrasonography guided (12-14 cores) or transperineal (median 32 cores) biopsy. Multivariate Cox hazards regression analysis was undertaken to determine (i) risk of upgrading, (ii) clinical or radiological suspicion of disease progression, and (iii) transitioning to active treatment. Suspicion of disease progression was defined as any biopsy upgrading, >30% positive cores, magnetic resonance imaging (MRI) Likert score >3/T3 or PSA level of >20ng/mL. Conversion to treatment included radical or hormonal treatment.

Among the 460 eligibleisk of subsequent upgrading, clinical or radiological suspicion of disease progression, and conversion to active treatment. A less intense surveillance protocol should be considered for this cohort of patients.
