Facilitators and Barriers to Using Selective Laser Trabeculoplasty (SLT) as First-Line Treatment for Glaucoma: Physician and Patient Views Gathered during an Exploratory Descriptive Qualitative Study

ABSTRACT Purpose To explore the perception of selective laser trabeculoplasty (SLT) among physicians and patients and the acceptance of using SLT as first-line treatment for glaucoma. Methods Exploratory descriptive qualitative study based on semi-structured interviews with glaucoma specialists and patients in two eye hospital of Zhejiang and Guangdong Provinces, China. Data were analyzed using the thematic analysis framework approach. Results 11 glaucoma specialists and 12 glaucoma patients were interviewed. Four themes were identified in the data: Physicians’ preferences for treatment types, patient views on treatment types, decision-making during the physician-patient encounter and feasibility of SLT as a first-line therapy. Advantages of SLT include safety and repeatability with limited side effects. However, concerns about the durability of the effect of the treatment were often mentioned by both physicians and patients. Some factors such as practice preference, personal motivation and patient characteristics may influence treatment choice. Most patients lack knowledge about SLT and hold high expectations of their treatments. Physicians report insufficient evidence supporting the use of SLT as first line therapy. Physicians report the need for locally relevant, evidence-based guidelines regarding the use of SLT in the treatment of glaucoma. Conclusions SLT was suggested as the first-line treatment of glaucoma due to its reliable efficacy and potential advantage. Results from our study offer important insight into barriers of increasing the uptake of SLT, which also provides some guidance for the use of SLT in the future.
Evidence of Coinfections between SARS-CoV-2 and Select Arboviruses in Guerrero, Mexico, 2020–2021

ABSTRACT. We provide evidence of concurrent and close sequential infections between SARS-CoV-2 and select arboviruses—namely, chikungunya virus (CHIKV); dengue viruses 1, 2, and 3 (DENV1–3), and Zika virus (ZIKV)—in patients in Guerrero, southwest Mexico, in 2020–2021. The study population consisted of 176 febrile patients with laboratory evidence of SARS-CoV-2 infection. Sera from all patients were serologically and antigenically tested for seven arboviruses known to occur in Guerrero. Eighteen patients contained CHIKV IgM, six of whom also contained CHIKV RNA. Another 16 patients contained flavivirus antigen. The flaviviruses responsible for the infections were identified by plaque reduction neutralization test as DENV1 (two patients), DENV2 (five patients), DENV3 (three patients), ZIKV (three patients), and an undetermined flavivirus (three patients). In summary, we identified patients in Guerrero, Mexico, with concurrent or recent sequential infections between SARS-CoV-2 and select arboviruses, exemplifying the importance of performing differential diagnosis in regions where these viruses cocirculate.
The usefulness of maternally inherited genetic markers for phylogeographic studies in village chicken

Abstract Phylogeography plays a major role in understanding micro and macroevolutionary processes dealing with evolutionary interpretations of geographical distribution. This field integrates information from molecular genetics, population genetics, demography, and phylogeny for the interpretation of the geographical distribution of lineages. The full mtDNA sequence and W chromosome polymorphisms were exploited to assess the usefulness of two maternally-inherited genetic markers for phylogeographic studies of village chickens. We studied 243 full mtDNA sequences from three countries (Iraq, n = 27; Ethiopia, n = 211; and Saudi Arabia, n = 5) and a 13-kb fragment of the W chromosome from 20 Iraqi and 137 Ethiopian female chickens. The results show a high level of genetic diversity for the mtDNA within and among countries as well as within populations. On the other hand, sequence analysis of the W chromosome shows low genetic diversity both within and among populations. Six full mtDNA haplogroups (A, B, C1, C2, D1, and E1) were observed and 25 distinct W haplotypes. The results support the effectiveness of full mtDNA sequences but not the W chromosome in tracing the maternal historical genome background with, however, weak within a country phylogeographic signal.
Workplace wellness programs targeting weight outcomes in men: A scoping review

Workplaces have been identified as a priority setting for the delivery of wellness programs to address risk factors for overweight and obesity. Men in particular may benefit greatly from these types of programs as they are typically harder to engage in health promotion. A scoping review was performed to provide an overview of interventions that have been implemented within the workplace that target weight outcomes in men. A searched of six electronic databases (Medline, Embase, CINAHL, Scopus, Cochrane Database of Systematic Review, and Business Source Ultimate) was conducted from January 2010 to August 2020. Of the 2191 articles identified, 25 were included. The majority took place in North America or Europe (72%). Over half (n = 17, 68%) utilized both a nutrition and physical activity component. Thirteen of the 19 articles (68%) that reported weight as an outcome showed the program to be efficacious in reducing weight. Overall, only seven articles were solely focused on an all‐male population. Workplace wellness programs targeting weight outcomes in men have been conducted to some extent, with majority being successful in reducing weight. However, there is a need for more randomized controlled trials (RCTs), long‐term follow‐up, and male‐only programs.
Can slowing the rate of water temperature decline be utilized to reduce the impacts of cold water pollution from dam releases on fish physiology and performance?

Abstract Cold water pollution (CWP) is caused by releases of unseasonably cold water from large, thermally stratified dams. Rapid and prolonged decreases in water temperature can have depressive effects on the metabolism, growth and swimming performance of fish. However, it is unknown if reducing the rate of temperature decrease could mitigate these negative effects by allowing thermal acclimation/acclimatization to occur. This study investigated the rate of temperature decrease as a potential CWP mitigation strategy in juvenile Murray cod Maccullochella peelii. M. peelii were exposed to a gradual, intermediate or rapid temperature decrease from 24 to 14°C. Energetic costs, locomotor performance, growth and survival were measured to determine if the initial thermal regime affected the thermal acclimation capacity of M. peelii. Cold exposure had significant acute and lasting depressive effects regardless of the rate of temperature decrease, although M. peelii showed varying degrees of thermal compensation in swimming performance and metabolism after 8 weeks of exposure to low temperatures. The short‐term effects of CWP‐like reductions in temperature are significant, but over time M. peelii can offset some of the depressive effects of CWP through thermal plasticity. This study highlights the importance of understanding physiological responses of fish to inform management and conservation. We conclude that rate of water temperature decline cannot be used to mitigate the sublethal effects of CWP on juvenile M. peelii but may still be useful for managing the negative effects in other native Australian fish species.
Impact of dual-focus soft contact lens wear on near work-induced transient myopia

ABSTRACT Clinical relevance Dual-focus soft contact lenses are effective in slowing myopia progression; however, their influence on near work-induced transient myopia (NITM) remains unknown. When performing a 5-min near task at 20 cm, we observed that dual-focus soft contact lens wear induced greater lags of accommodation and a lower initial NITM than single-vision soft contact lenses, which provides relevant information for better understanding the impact of using this optical design on the accommodative function. Background NITM has been proposed as a myogenic factor, although it is a matter of debate by the scientific community. The main objective of this study was to assess the short-term effect of wearing dual-focus soft contact lenses for myopia control on the steady-state accommodative response and NITM. Methods Twenty-four young myope adults wore, on two different days, dual-focus and single-vision soft contact lenses, while the accommodative response was dynamically measured with an open-field autorefractor during the execution of the NITM task. The shift and the time required to recover baseline levels in the refractive state after performing the 5-min near task (20 cm) were the main dependent variables. Results We found a lower magnitude of accommodation during the execution of the near task with the dual-focus in comparison to the single-vision soft contact lenses (p < 0.001). There was a lower initial NITM with the dual-focus when compared to the single-vision lenses (corrected p-value = 0.003, Cohen’s d = 0.68), but no statistically significant differences were observed for decay duration (p = 0.984). Conclusions Dual-focus soft contact lens wear causes a reduced accommodative response during a near task, and an initial small myopic shift at distance after a 5-min period of near viewing. The current findings may help to understand the mechanisms involved in myopia control with this optical strategy.
CHAF1A/B mediate silencing of unintegrated HIV-1 DNAs early in infection

Significance Invading viral DNAs constitute a high risk for the infected cell and are high-profile targets of antiviral host factors. Nevertheless, little is known about the silencing machinery in the nucleus that acts to prevent transcription or retroviral integration of extrachromosomal DNA. We here identified CHAF1A and CHAF1B as two players that mediate silencing of unintegrated HIV-1 DNAs. Our findings provide evidence that these factors act independently of their canonical nucleosome assembly complex to induce silencing early in infection. The characterization of the intrinsic cellular defense mechanism against incoming DNA is relevant to transient gene delivery, as mediated by virus-based vectors in gene therapy. Early events of the retroviral life cycle are the targets of many host restriction factors that have evolved to prevent establishment of infection. Incoming retroviral DNAs are transcriptionally silenced before integration in most cell types, and efficient viral gene expression occurs only after formation of the provirus. The molecular machinery for silencing unintegrated retroviral DNAs of HIV-1 remains poorly characterized. Here, we identified the histone chaperones CHAF1A and CHAF1B as essential factors for silencing of unintegrated HIV-1 DNAs. Using RNAi-mediated knockdown (KD) of multiple histone chaperones, we found that KD of CHAF1A or CHAF1B resulted in a pronounced increase in expression of incoming viral DNAs. The function of these two proteins in silencing was independent of their interaction partner RBBP4. Viral DNA levels accumulated to significantly higher levels in CHAF1A KD cells over controls, suggesting enhanced stabilization of actively transcribed DNAs. Chromatin immunoprecipitation assays revealed no major changes in histone loading onto viral DNAs in the absence of CHAF1A, but levels of the H3K9 trimethylation silencing mark were reduced. KD of the H3K9me3-binding protein HP1γ accelerated the expression of unintegrated HIV-1 DNAs. While CHAF1A was critical for silencing HIV-1 DNAs, it showed no role in silencing of unintegrated retroviral DNAs of mouse leukemia virus. Our study identifies CHAF1A and CHAF1B as factors involved specifically in silencing of HIV-1 DNAs early in infection. The results suggest that these factors act by noncanonical pathways, distinct from their histone loading activities, to mediate silencing of newly synthesized HIV-1 DNAs.
Computed Tomography-Guided Percutaneous Radiofrequency Ablation in Older Adults With Early-Stage Peripheral Lung Cancer: A Retrospective Cohort Study

Objectives To evaluate the feasibility, safety, and efficacy of computed tomography(CT)-guided percutaneous radiofrequency ablation (RFA) in medically inoperable older adults with clinical stage I non-small cell lung cancer (NSCLC). Patients and Methods We retrospectively reviewed the records of medically inoperable older adults (≥70 years) with clinical stage I NSCLC who underwent percutaneous multi-tined electrode RFA at our institution between January 2014 and December 2018. We analyzed the patients’ characteristics, therapy response, survival, as well as the procedure-related complications. Results Eighteen patients (10 men and 8 women) with a mean age of 75.9 (71−85) years were treated in during the study period. The median tumor size was 25 mm (range, 19−43 mm); 10 and 8 cases involved stage T1 and T2a disease, respectively. The median follow-up duration was 25 (11–45) months. RFA was technically successful for all 18 lesions, with no treatment-related mortality. The disease control rate was 83.3% (15/18 lesions). There were 6 cases of pneumothorax: one symptomatic case requiring thoracic drainage, and five requiring no treatment. Minor complications, including pulmonary infection, chest pain, fever, and cough, were treated within 4 days (range, 1−4 days). The progression-free survival rates were 83.3%, 64.9%, and 51.9% 1, 2, and 3 years, respectively. The corresponding overall survival rates were 92.2%, 81.5%, and 54.3%, respectively. Conclusions CT-guided percutaneous RFA is safe and effective in medically inoperable patients with stage I NSCLC and could be an alternative therapeutic strategy, particularly in older adults with early-stage peripheral lung cancer.
Variation in Breast Cancer Risk Model Estimates Among Women in Their 40s Seen in Primary Care.

Background: The Gail, Breast Cancer Surveillance Consortium (BCSC), and Tyrer-Cuzick breast cancer risk prediction models are recommended for use in primary care. Calculating breast cancer risk is particularly important for women in their 40s when deciding on mammography, with some guidelines recommending screening for those with 5-year risk similar to women age 50 (≥1.1%). Yet, little is known about risk estimate agreement among models for these women. Materials and Methods: Four hundred nine Boston-area women 40-49 years of age completed a risk questionnaire before a primary care visit to compute their breast cancer risk. The kappa statistic was used to examine when (1) Gail and BCSC agreed on 5-year risk ≥1.1%; (2) Gail estimated 5-year risk ≥1.7% and Tyrer-Cuzick estimated 10-year risk ≥5% (guideline thresholds for recommending prevention medications); and when (3) Gail and Tyrer-Cuzick agreed on lifetime risk ≥20% (threshold for breast MRI using Tyrer-Cuzick). Results: Participant mean age was 44.1 years, 56.7% were non-Hispanic white, and 7.8% had a first-degree relative with breast cancer. Of 266 with breast density information to estimate both Gail and BCSC, the models agreed on 5-year risk being ≥1.1% for 36 women, kappa = 0.34 (95% confidence interval: 0.23-0.45). Gail and Tyrer-Cuzick estimates led to agreement about prevention medications for 8 women, kappa 0.41 (0.20-0.61), and models agreed on lifetime risk ≥20% for 3 women, kappa 0.08 (-0.01 to 0.16). Conclusions: There is weak agreement on breast cancer risk estimates generated by risk models recommended for primary care. Using different models may lead to different clinical recommendations for women in their 40s.
Clinical characteristics, biochemical parameters and insulin response to oral glucose tolerance test (OGTT) in 25 transfusion dependent β-thalassemia (TDT) patients recently diagnosed with diabetes mellitus (DM)

Background: Patients with transfusion dependent β-thalassemia (TDT) are at high risk for developing, over the time, a form of diabetes distinct from type 1 and type 2 diabetes, but with similarities to both. Aims of study: The aim of this study is to describe the clinical and laboratory data, and the insulin secretion and sensitivity, in TDT patients recently diagnosed with diabetes mellitus (DM). Materials and Methods: The medical records of 25 TDT patients with DM, diagnosed by standardized oral glucose tolerance test (OGTT) and insulin secretion, were analysed; data were compared to TDT patients without diabetes and to a group of healthy subjects. Natural history of glucometabolic status before the diagnosis of DM was also reviewed. Results: On average, the TDT patients with DM were younger compared to TDT patients without diabetes. The mean age at diagnosis of DM in female and male TDT patients was 24.0 ± 7.1 years and 31.9 ± 5.6 years, respectively (P: 0.007). Serum alanine aminotransferase values, basal insulin levels and prevalence of hypogonadism were consistently higher in TDT patients with DM compared to those without diabetes. Decreased insulin secretion and increased insulin resistance was observed in patients with DM. Conclusion: The natural history of glucometabolic status in TDT patients is characterized by a deterioration of glucose tolerance over time. Iron overload and liver dysfuction are the main factors responsible for glucose disturbances (GD) in TDT patients. The therapeutic approach must be individualized and followed by a multidisciplinary team. (www.actabiomedica.it)
Use of multiple polygenic risk scores for distinguishing schizophrenia-spectrum disorder and affective psychosis categories in a first-episode sample; the EU-GEI study

Abstract Background Schizophrenia (SZ), bipolar disorder (BD) and depression (D) run in families. This susceptibility is partly due to hundreds or thousands of common genetic variants, each conferring a fractional risk. The cumulative effects of the associated variants can be summarised as a polygenic risk score (PRS). Using data from the EUropean Network of national schizophrenia networks studying Gene-Environment Interactions (EU-GEI) first episode case–control study, we aimed to test whether PRSs for three major psychiatric disorders (SZ, BD, D) and for intelligent quotient (IQ) as a neurodevelopmental proxy, can discriminate affective psychosis (AP) from schizophrenia-spectrum disorder (SSD). Methods Participants (842 cases, 1284 controls) from 16 European EU-GEI sites were successfully genotyped following standard quality control procedures. The sample was stratified based on genomic ancestry and analyses were done only on the subsample representing the European population (573 cases, 1005 controls). Using PRS for SZ, BD, D, and IQ built from the latest available summary statistics, we performed simple or multinomial logistic regression models adjusted for 10 principal components for the different clinical comparisons. Results In case–control comparisons PRS-SZ, PRS-BD and PRS-D distributed differentially across psychotic subcategories. In case–case comparisons, both PRS-SZ [odds ratio (OR) = 0.7, 95% confidence interval (CI) 0.54–0.92] and PRS-D (OR = 1.31, 95% CI 1.06–1.61) differentiated AP from SSD; and within AP categories, only PRS-SZ differentiated BD from psychotic depression (OR = 2.14, 95% CI 1.23–3.74). Conclusions Combining PRS for severe psychiatric disorders in prediction models for psychosis phenotypes can increase discriminative ability and improve our understanding of these phenotypes. Our results point towards the potential usefulness of PRSs in specific populations such as high-risk or early psychosis phases.
Unique molecular and functional features of extramedullary hematopoietic stem and progenitor cell reservoirs in humans

Rare hematopoietic stem and progenitor cell (HSPC) pools outside the bone marrow (BM) contribute to blood production in stress and disease but remain ill-defined. Although non-mobilized peripheral blood (PB) is routinely sampled for clinical management, the diagnosis and monitoring potential of PB HSPCs remains untapped, as no healthy PB HSPC baseline has been reported. Here we comprehensively delineate human extramedullary HSPC compartments comparing spleen, PB and mobilized PB (mPB) to BM using single-cell RNA-seq and/or functional assays. We uncover HSPC features shared by extramedullary tissues and others unique to PB. First, in contrast to actively dividing BM HSPCs, we find no evidence of substantial ongoing hematopoiesis in extramedullary tissues at steady state, but report increased splenic HSPC proliferative output during stress erythropoiesis. Second, extramedullary stem cells/multipotent progenitors (HSC/MPPs) from spleen, PB and mPB share a common transcriptional signature and increased abundance of lineage-primed subsets compared to BM. Third, healthy PB HSPCs display a unique bias towards erythroid-megakaryocytic differentiation. At HSC/MPP level, this is functionally imparted by a subset of phenotypic CD71+ HSC/MPPs, exclusively producing erythrocytes and megakaryocytes, highly abundant in PB but rare in other adult tissues. Finally, the unique erythroid-megakaryocytic-skewing of PB is perturbed with age, in essential thrombocythemia and in beta-thalassemia. Collectively, we identify extramedullary lineage-primed HSPC reservoirs that are non-proliferative in situ and report involvement of splenic HSPCs during demand-adapted hematopoiesis. Our data also establish aberrant composition and function of circulating HSPCs as potential clinical indicators of BM dysfunction.
Technical efficacy and safety of CT-guided transforaminal periradicular infiltration using CT foot switches and MPR images

Purpose: To demonstrate the technical efficacy and safety of CT-guided transforaminal periradicular infiltration in the treatment of the radicular pain without surgical intervention, using CT foot switches and MPR images. Materials and Methods: Four hundred and eighty two patients (286 males and 196 females, age range 27-71 years, mean age 56 years) with a unilateral or bilateral radiculopathy who underwent CT-guided transforaminal periradicular infiltration without surgical intervention, were retrospectively selected in the period from January 2019 to February 2020. Patients who had received surgery for herniated disc or laminectomy, patients with a previous vertebral fractures, and patients with inflammatory syndrome or risk of bleeding were excluded. Results: There were no major or minor clinically relevant complications. Many patients a marked reduction or resolution of pain after the CT-guided infiltration (P<0.05). No patient required hospitalization. One patient reported an episode of intense headache, which resolved after twenty minutes. In eleven cases, a slight increase in pain related to spinal compression caused by the administration of the drug was reported, even if administrated extremely slowly. Sixteen patients reported pain in the upper limbs during and after the procedure, however this was not related to infiltration but to the forced and prolonged arm position. Conclusion: CT-guided transforaminal periradicular infiltration is a semi-invasive and well tolerated procedure, moreover it has a reduced comorbidity and no observed major or minor complications. The CT foot switches and MPR evaluation may help to make the procedure more efficient. (www.actabiomedica.it)
