To identify predictive pathological factors for local recurrence (LR) and to study the impact of LR on survival in patients treated with glansectomy for penile squamous cell carcinoma (pSCC).

We retrospectively studied patients treated with glansectomy at international, high-volume reference centres. check details We analysed histopathological predictors of LR, stratified patients into risk groups based on the number of risk factors present, and studied the impact of LR on survival outcomes using Kaplan-Meier survival analysis and stepwise Cox proportional hazards regression models. Subsequently, we performed sensitivity analyses excluding margin-positive cases, pT3 disease, and cN+ disease, or all of these factors.

Across nine institutions, 897 patients were included, of whom 94 experienced LR. On multivariable analysis, presence of high-grade disease and pT3 stage were independent predictors of LR. LR-free survival rates significantly differed according to the number of risk factors present, with a hazard ratio (HR and clearly challenging the dogma of using organ-sparing surgery whenever possible since survival is unaffected by higher LR rates.

Pathological T3 stage and presence of high-grade disease were independent histopathological predictors of LR after glansectomy for primary pSCC, which allowed risk stratification into three groups with significantly different risk of developing LR. Additionally, LR is related to poor OS and CSS, indicating that LR is a manifestation of underlying aggressive disease and clearly challenging the dogma of using organ-sparing surgery whenever possible since survival is unaffected by higher LR rates.Abiotic stresses, such as drought and salinity, adversely affect rice production and cause a severe threat to food security. Conventional crop breeding techniques alone are inadequate for achieving drought stress tolerance in crop plants. Using transgenic technology, incremental improvements in tolerance to drought and salinity have been successfully attained via manipulation of gene(s) in several crop species. However, achieving the goal via pyramiding multiple genes from the same or different tolerance mechanisms has received little attention. Pyramiding of multiple genes can be achieved either through breeding, by using marker-assisted selection, or by genetic engineering through molecular stacking co-transformation or re-transformation. Transgene stacking into a single locus has added advantages over breeding or re-transformation since the former assures co-inheritance of genes, contributing to more effective tolerance in transgenic plants for generations. Drought, being a polygenic trait, the potential candidate genes for gene stacking are those contributing to cellular detoxification, osmolyte accumulation, antioxidant machinery, and signaling pathways. Since cellular dehydration is inbuilt in salinity stress, manipulation of these genes results in improving tolerance to salinity along with drought in most of the cases. link2 In this review, attempts have been made to provide a critical assessment of transgenic plants developed through transgene stacking and approaches to achieve the same. Identification and functional validation of more such candidate genes is needed for research programs targeting the gene stacking for developing crop plants with high precision in the shortest possible time to ensure sustainable crop productivity under marginal lands.

Dentists are susceptible to musculoskeletal disorders due to prolonged static postures during dental treatments. link3 Using a magnification tool like dental operating microscope (DOM) or the dental loupes may correct the operator's posture. Up until now, few studies have focused on preclinical dental students' posture when working with the DOM, while most of them have focused on the loupes. The aim of this study was to comparatively analyse the working posture of preclinical students during a dental restoration procedure, working with two different magnification methods.

This study used a randomised cross-over design in which seventeen third year students were randomly divided into three groups. The exclusion criteria were previous contact with magnification systems and previous clinical working experience. Each student prepared 3 Black class 1 cavities on artificial lower molars first with no magnification, following dental loupes and DOM. They were video-recorded throughout the preparation. Trunk, neck and upper-arm position were evaluated using the Posture Assessment Instrument. Students completed a questionnaire on their subjective perception of the two magnification systems.

The statistical analysis showed significant improvement of the working posture using magnification systems compared to direct vision. The biggest improvement was obtained through the use of DOM, followed by the dental loupes. Students perceived dental loupes as being the most comfortable and easy to adapt to. They reported being more focused when using DOM.

Both magnification systems had a positive impact on the working posture, DOM having the best results. Loupes showed better adaptability while DOM showed better concentration.

Minocycline is a broad-spectrum antibiotic, effective as a chronic treatment for recurrent bacterial infections. Beyond its antibiotic action, minocycline also has important anti-inflammatory, antioxidant and antiapoptotic properties. Its efficacy has therefore been evaluated in many neurodegenerative and psychiatric diseases that have an inflammatory basis. Our aim was to review preclinical and clinical studies performed in neurological and psychiatric diseases whose treatment involved the use of minocycline and thereby to discern the possible beneficial effect of minocycline in these disorders.

Completed and ongoing preclinical studies and clinical trials of minocycline for both neurodegenerative diseases and psychiatric disorders, published from January 1995 to January 2020, were identified through searching relevant databases (https//www.ncbi.nlm.nih.gov/pubmed/, https//clinicaltrials.gov/). A total of 74 preclinical studies and 44 clinical trials and open-label studies were selected.

The results oflly is a useful drug in the treatment of these pathologies.

This is an update of a Cochrane Review first published in 2005. Cervical dystonia is the most common form of focal dystonia, and is a highly disabling movement disorder, characterised by involuntary, usually painful, head posturing. Currently, botulinum toxin type A (BtA) is considered the first line therapy for this condition.

To compare the efficacy, safety, and tolerability of BtA versus placebo, in people with cervical dystonia.

We searched Cochrane Movement Disorders' Trials Register, CENTRAL, MEDLINE, Embase, reference lists of articles, and conference proceedings in July 2020. All elements of the search, with no language restrictions, were last run in July 2020.

Double-blind, parallel, randomised, placebo-controlled trials (RCTs) of BtA versus placebo in adults with cervical dystonia.

Two review authors independently assessed records, selected included studies, extracted data using a paper pro forma, and evaluated the risk of bias. We resolved disagreements by consensus or by consulting a thi no data from RCTs evaluating the effectiveness and safety of repeated BtA injection cycles. There is no evidence from RCTs to allow us to draw definitive conclusions on the optimal treatment intervals and doses, the usefulness of guidance techniques for injection, the impact on quality of life, or the duration of treatment effect.

We have previously shown that carotid body stimulation by lysophosphatidic acid elicits a reflex stimulation of vagal efferent activity sufficient to cause bronchoconstriction in asthmatic rats. Here, we show that pathophysiological concentrations of asthma-associated prototypical Th2 cytokines also stimulate the carotid bodies. Stimulation of the carotid bodies by these asthmakines involves a PKCε-transient receptor potential vanilloid 1 (TRPV1) signalling mechanism likely dependent on TRPV1 S502 and T704 phosphorylation sites. As the carotid bodies' oxygen sensitivity is independent of PKCε-TRPV1 signalling, systemic blockade of PKCε may provide a novel therapeutic target to reduce allergen-induced asthmatic bronchoconstriction. Consistent with the therapeutic potential of blocking the PKCε-TRPV1 pathway, systemic delivery of a PKCε-blocking peptide suppresses asthmatic respiratory distress in response to allergen and reduces airway hyperresponsiveness to bradykinin.

The autonomic nervous system orchestng either PKCε or TRPV1. Further, we demonstrate that systemic PKCε blockade reduces asthmatic respiratory distress in response to allergen and airway hyperresponsiveness. These discoveries support an inflammation-dependent, oxygen-independent function for the carotid body and suggest that targeting PKCε provides a novel therapeutic option to abate allergic airway disease without altering life-saving autonomic hypoxic reflexes.The provision of safe nutrition care to patients is the fundamental vision of the American Society for Parenteral and Enteral Nutrition (ASPEN). Yet we are facing important challenges in our field and society, requiring us to reflect, rethink, and adjust to make new breakthroughs to meet the needs for the future. In developing new plans to address these challenges, we must focus on 2 critical elements people and the scientific process. Government and organizations cannot carry on their missions without people. But with the challenges of healthcare finance, biotechnology disruption, the desire to facilitate knowledge transfer and now the impact of the global pandemic, we need to develop a forward-thinking and sustainable approach to connect people and foster continued learning. Burnout is a recognized occupational problem that affects providers and researchers across all disciplines. The coronavirus disease 2019 pandemic has amplified the challenges associated with burnout. Supporting the needs and promoting the well-being of people, therefore, are critical to move forward successfully. At the same time, the scientific advances in our field rely on sound scientific principles and integrity. Information overload, pressure to produce immediate outcomes (such as cost-saving initiatives), and misinformation can compromise the scientific process and research evidence. The two common missteps that affect researchers, clinicians, and administrators include premature factulation and binary thinking. We will discuss how these missteps can occur and the approaches to minimize their influence in making sound decisions and policies to meet the future's needs.

The aim of this study was to describe the successful epilation of intraoral grafts using the diode laser system.

Two male patients at a 12-month follow-up - who underwent radical resection of oral cancer located in the mouth floor and tongue followed by reconstruction with cutaneous flap - showed hypertrichosis in the graft region, leading to dysphagia and dysphonia. The diode (980 nm) laser was performed for both cases in order to remove the ectopic hair. Excellent aesthetic and functional outcomes with total hair removal and alteration of the tissue surface were achieved.

There is no currently standard protocol for the laser epilation use on hairy grafts because each graft required a different number of sessions for total epilation. The diode laser system appears to be a successful therapeutic option for patients suffering from hypertrichrosis in the oral cavity.
