In cancers and chronic conditions, peer support (PS) has been shown to improve quality of life (QOL) and provide an important coping mechanism for patients, however there is little evidence for this intervention in Head and Neck cancer (HNC). Peer support allows individuals to come together and share information, encouragement, and experiences. It is delivered in a variety of ways including one-to-one, online, and support groups. There is limited literature regarding the timing, barriers, and types of PS available for individuals with HNC across the United Kingdom (UK). The aim of this project was to survey healthcare professionals with respect to their experience regarding types, timings, and barriers to PS in HNC. The survey was developed based on the literature, feedback and advice from a HNC patient research group and healthcare professionals. It was conducted online and consisted of twelve questions. Eighty-eight individuals responded covering twenty-four of twenty-six cancer alliances across the UK. Three main themes with subthemes were identified patient barriers (emotional barriers and patient limitations), organisational barriers (administrative problems, limited time and resources and COVID-19), and staff barriers (lack of departmental support, concerns with PS and matching and timing of support). The survey demonstrated the different types of PS available across the UK and the barriers faced when implementing this support. It highlighted the complexity of being able to satisfactorily deliver appropriate and effective PS in HNC and the challenges involved.
In utero exposure to bisphenols, widely used in consumer products, may alter lung development and increase the risk of respiratory morbidity in the offspring. However, evidence is scarce and mostly focused on bisphenol A (BPA) only.

To examine the associations of in utero exposure to BPA, bisphenol F (BPF), and bisphenol S (BPS) with asthma, wheeze, and lung function in school-age children, and whether these associations differ by sex.

We included 3,007 mother-child pairs from eight European birth cohorts. Bisphenol concentrations were determined in maternal urine samples collected during pregnancy (1999-2010). Between 7 and 11years of age, current asthma and wheeze were assessed from questionnaires and lung function by spirometry. Wheezing patterns were constructed from questionnaires from early to mid-childhood. We performed adjusted random-effects meta-analysis on individual participant data.

Exposure to BPA was prevalent with 90% of maternal samples containing concentrations above detection limits. BPF and BPS were found in 27% and 49% of samples. In utero exposure to BPA was associated with higher odds of current asthma (OR=1.13, 95% CI=1.01, 1.27) and wheeze (OR=1.14, 95% CI=1.01, 1.30) (p-interaction sex=0.01) among girls, but not with wheezing patterns nor lung function neither in overall nor among boys. We observed inconsistent associations of BPF and BPS with the respiratory outcomes assessed in overall and sex-stratified analyses.

This study suggests that in utero BPA exposure may be associated with higher odds of asthma and wheeze among school-age girls.

Exceptional cases of retroperitoneal and posterior mediastinal located Mullerian cysts have been reported. When located in the retroperitoneum, those cysts are often confused with other retroperitoneal cysts such as cystic lymphangioma and cystic mesothelioma of peritoneum because of the poor clinical picture and a nonspecific radiologic presentation. The histopathological analysis is essential to make the diagnosis, and the positive staining of a Müllerian marker is a decisive argument in favor of a Müllerian cyst. click here Here, we report a case of an incidental finding of a retroperitoneal Müllerian cyst in a 68-years-old woman.Recently, the term 'aphantasia' has become current in scientific and public discourse to denote the absence of mental imagery. However, new terms for aphantasia or its subgroups have recently been proposed, e.g., 'dysikonesia' or 'anauralia', which complicates the literature, research communication and understanding for the general public. Before further terms emerge, we advocate the consistent use of the term 'aphantasia' as it can be used flexibly and precisely, and is already widely known in the scientific community and among the general public.LEGO® is a brand of toys that have entertained generations of children. Beyond amusement, LEGO® bricks also constitute a building ecosystem of their own that creators from the general public, as well as scientists and engineers, can use to design and assemble devices for all purposes, including scientific research and biotechnology. We describe several of these constructions to highlight the construction properties of LEGO® and their advantages, caveats, and impact in biotechnology. We also discuss how this emerging trend in LEGO® building pairs with a growing interest in open-access and frugal science which aims to provide access to technology to all scientists regardless of financial wealth and technological prowess.2020 was a significant year because of the occurrence of two simultaneous public health crises the coronavirus pandemic and the public health crisis of racism brought into the spotlight by the murder of George Floyd. The coronavirus pandemic has affected all aspects of health care, particularly the delivery of surgical care, surgical education, and academic productivity. The concomitant public health crisis of racism and health inequality during the viral pandemic highlighted opportunities for action to address gaps in surgical care and the delivery of public health services. At the 2021 Academic Surgical Congress Hot Topics session on flexibility and leadership, we also explored how our military surgeon colleagues can provide guidance in leadership during times of crisis. The following is a summary of the issues discussed during the session and reflections on the important lessons learned in academic surgery over the past year.
Secondary hyperparathyroidism affects nearly all patients with renal failure on dialysis. Medical treatment of secondary hyperparathyroidism has considerably evolved over the past 2 decades, with parathyroidectomy reserved for severe cases. The primary objective of our study was to understand how trends in medical treatments affected parathyroidectomy rates in patients with secondary hyperparathyroidism on dialysis.

We used the United States Renal Data System to identify 379,835 adult patients (age ≥18) who were on maintenance dialysis in the United States between 2006 and 2016 with Medicare as the primary payor and ascertained treatment for secondary hyperparathyroidism. Adjusted rate ratios for rates of parathyroidectomy were calculated using multivariable-adjusted Poisson regression.

Of 379,835 secondary hyperparathyroidism patients, 4,118 (1.1%) underwent parathyroidectomy, 39,835 (10.5%) received cinacalcet, 243,522 (64.1%) received phosphate binders, 17,571 (4.6%) received vitamin D analogs, and 8atments and an increase in the use of calcimimetics to treat secondary hyperparathyroidism, parathyroidectomy rates have been steadily increasing among dialysis patients with Medicare coverage.
One of the types of catabolic processes in cells is autophagy, which maintains cell homeostasis. It is also known as a defense response to oxidative stress. This study aimed to track the autophagic activity of testicular tissue in mature and immature rats in 3 conditions (1) physiologic, (2) under increased pressure in the tunica albuginea compartment following the induction of testicular torsion, and (3) decompression of this compartment by flap technique.

This study was performed on 72 Wistar rats divided into 3 mature and 3 immature groups, each of the groups including Sham group, testicular torsion induction group for 6 hours (Torsion Detorsion), and testicular torsion induction group for 6 hours, followed by the flap technique.

In the physiologic state or Sham, autophagic indices (LC3, Beclin-1) are active, and more activity was observed in mature rats, compared with immature ones, which indicated the activity of this process during development and maturity. In the Torsion Detorsion group, significant expression of autophagy and apoptosis indices (caspase3) was observed along with the degradation of spermatogenesis and steroidogenesis. It seems that in this state, the activation of autophagy leads to programmed death and is in line with apoptosis. Finally, in the flap technique group, an increase in the expression of autophagy indices was accompanied by a reduction in the expression of apoptotic indices and improved spermatogenesis and steroidogenesis.

Decompression of tunica albuginea by flap technique can activate of autophagy process to save tissue function and eliminate stress caused by testicular torsion.

Technical difficulties are occasionally encountered when performing conventional minimally invasive esophagectomy and robot-assisted minimally invasive esophagectomy in patients with a narrow thoracic cavity. Thoracic cavity-to-cage ratio is an indicator of thoracic cavity length. We hypothesized that the thoracic cavity-to-cage ratio could be a predictor of technical difficulties in conventional minimally invasive esophagectomy and robot-assisted minimally invasive esophagectomy.

We evaluated 340 patients who underwent minimally invasive esophagectomy for esophageal squamous cell carcinoma between April 2010 and March 2021. Thoracic cavity-to-cage ratio was calculated as the diameter of the thoracic cavity to that of the thoracic cage at the brachiocephalic vein, tracheal bifurcation, and inferior right pulmonary vein levels. Moreover, thoracic cavity-to-cage ratio score, which is an indicator of the whole thoracic cavity length based on the thoracic cavity-to-cage ratio at the 3 levels, was defined. Theedictor of technical difficulties in both conventional minimally invasive esophagectomy and robot-assisted minimally invasive esophagectomy.Lipoprotein(a), or Lp(a), levels and the effect of proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibition on Lp(a) during the peri-infarction and early postinfarction period are not well characterized. This study aimed to describe the trajectory of Lp(a), as well as the effect of PCSK9 inhibition on that trajectory during the peri-infarction and early postinfarction period. Lp(a) levels were obtained within 24 hours of hospital admission as well as within 24 hours of hospital discharge and at 30 days from 74 participants who presented with a NSTEMI (troponin I >5 ng/ml) or with a STEMI and were enrolled in 2 randomized, double-blind trials of evolocumab and placebo (Evolocumab in Acute Coronary Syndrome [EVACS I]; ClinicalTrials.gov, NCT03515304 and Evolocumab in Patients With STEMI [EVACS II]; ClinicalTrials.gov Identifier NCT04082442). There was a significant increase from the pretreatment level in the placebo-treated patients, from 64 (41,187) nmol/L to 80 (47, 172) nmol/L at hospital discharge and to 82 (37, 265) at 30 days.
