RESUMEN

BACKGROUND: Since their development, integrated plastic and reconstructive surgery (PRS) residency training programs have established diverse methods of incorporating general surgery training into graduate medical education. Programs have questioned the necessary duration and timing of such training. The aim of this study is to assess the landscape of general surgery exposure in integrated PRS residency programs. METHODS: Thirty-six integrated PRS residency programs were included based on the availability of postgraduate year (PGY)-level rotation data. Rotations were measured in units of weeks with descriptive titles maintained as advertised by the program. Individual general surgery rotations were also categorized as being either PRS-aligned, American Board of Plastic Surgery (ABPS) Required Clinical (RC) or ABPS Strongly Suggested (SS). Statistical analyses were carried out on the relative proportions of each subcategory in the 2 parent groups. RESULTS: All 36 programs evaluated required general surgery rotations in years PGY- 1 to -2. By PGY-3, 69% of programs required general surgery, and by PGY-6, 25%, and these were limited to 4- to 6-week rotations in burn, breast, or trauma. Looking across all 6 years, with 312 weeks of training total, the minimum number of weeks spent in general surgery rotations was 32, and the maximum number was 119, with an average of 61 weeks (±21).Programs were subcategorized into 2 groups based on whether they spent more (n = 16) or less (n = 20) than the net average number of weeks in ABPS RC + SS rotations. No significant difference was found in the relative proportion of PRS-aligned general surgery across groups. Programs with <60 weeks of general surgery had a relatively greater proportion of ABPS RC and SS rotations. CONCLUSIONS: These data demonstrate that there exists significant variability in overall duration of general surgery training across integrated PRS training programs. When controlling overall general surgery exposure for variables of interest like PRS-aligned exposure or compatibility with ABPS requirements, we found no discernable educational model or patterns to explain the observed range in exposure. These results warrant reexamination of an ideal general surgery track within the integrated plastic surgery training model that optimizes training for the PRS resident.

RESUMEN

Importance: Low back and neck pain are often self-limited, but health care spending remains high. Objective: To evaluate the effects of 2 interventions that emphasize noninvasive care for spine pain. Design, Setting, and Participants: Pragmatic, cluster, randomized clinical trial conducted at 33 centers in the US that enrolled 2971 participants with neck or back pain of 3 months' duration or less (enrollment, June 2017 to March 2020; final follow-up, March 2021). Interventions: Participants were randomized at the clinic-level to (1) usual care (n = 992); (2) a risk-stratified, multidisciplinary intervention (the identify, coordinate, and enhance [ICE] care model that combines physical therapy, health coach counseling, and consultation from a specialist in pain medicine or rehabilitation) (n = 829); or (3) individualized postural therapy (IPT), a postural therapy approach that combines physical therapy with building self-efficacy and self-management (n = 1150). Main Outcomes and Measures: The primary outcomes were change in Oswestry Disability Index (ODI) score at 3 months (range, 0 [best] to 100 [worst]; minimal clinically important difference, 6) and spine-related health care spending at 1 year. A 2-sided significance threshold of .025 was used to define statistical significance. Results: Among 2971 participants randomized (mean age, 51.7 years; 1792 women [60.3%]), 2733 (92%) finished the trial. Between baseline and 3-month follow-up, mean ODI scores changed from 31.2 to 15.4 for ICE, from 29.3 to 15.4 for IPT, and from 28.9 to 19.5 for usual care. At 3-month follow-up, absolute differences compared with usual care were -5.8 (95% CI, -7.7 to -3.9; P < .001) for ICE and -4.3 (95% CI, -5.9 to -2.6; P < .001) for IPT. Mean 12-month spending was $1448, $2528, and $1587 in the ICE, IPT, and usual care groups, respectively. Differences in spending compared with usual care were -$139 (risk ratio, 0.93 [95% CI, 0.87 to 0.997]; P = .04) for ICE and $941 (risk ratio, 1.40 [95% CI, 1.35 to 1.45]; P < .001) for IPT. Conclusions and Relevance: Among patients with acute or subacute spine pain, a multidisciplinary biopsychosocial intervention or an individualized postural therapy intervention, each compared with usual care, resulted in small but statistically significant reductions in pain-related disability at 3 months. However, compared with usual care, the biopsychosocial intervention resulted in no significant difference in spine-related health care spending and the postural therapy intervention resulted in significantly greater spine-related health care spending at 1 year.

RESUMEN

BACKGROUND: Cardiovascular disorders are major complications of rheumatoid arthritis (RA). Hence, finding effective agents that can target RA progression and its cardiovascular consequences is demanding. The present work aimed to explore the potential of lisinopril, an angiotensin-converting enzyme inhibitor, to mitigate adjuvant's-induced arthritis with emphasis on the pro-inflammatory signals, articular degradation cues, and angiogenesis alongside JAK-2/STAT-3 and Nrf2/HO-1 pathways. METHODS: Lisinopril (10 mg/kg/day) was administered by oral gavage for 3 weeks and the target signals were examined by biochemical assays, ELISA, histopathology, immunoblotting, and immunohistochemistry. RESULTS: Lisinopril attenuated the progression of arthritis as proven by lowering paw edema, arthritic index, and gait scores alongside diminishing the immune-cell infiltration/aberrant histopathology in the dorsal pouch lining. These favorable actions were associated with curtailing the production of inflammatory cytokines (TNF-α, IL-6, IL-1ß, and IL-17) and the pro-inflammatory angiotensin II alongside upregulating the anti-inflammatory angiotensin-(1-7) in the hind paw of arthritic rats. At the molecular level, lisinopril inhibited the upstream JAK-2/STAT-3 pathway by downregulating the protein expression of p-JAK-2/total JAK-2 and p-STAT-3/total STAT-3 ratio and the nuclear levels of NF-κBp65. Meanwhile, lisinopril curbed the downstream cartilage degradation signals matrix metalloproteinases (MMP-3 and MMP-9) and the bone erosion cue RANKL. Equally important, the protein expression of the angiogenesis signal VEGF was downregulated in the hind paw/dorsal lining. With respect to oxidative stress, lisinopril suppressed the paw lipid peroxides and boosted GSH and Nrf-2/HO-1 pathway. CONCLUSION: Lisinopril attenuated adjuvant-induced arthritis via inhibition of inflammation, articular degradation cues, and angiogenesis.

RESUMEN

BACKGROUND: Cardiovascular disease (CVD) is the primary cause of death worldwide, accounting for 31.0% of all deaths and more than 18 million deaths annually. The 2008 World Health Report indicated that 144 (35%) of the 413 deaths per 100,000 in 2002 in the Kingdom of Saudi Arabia (KSA) were due to CVD. Primary prevention is an important focus of most of the cardiovascular prevention guidelines around the world. In this study, we aimed to describe the prevalence of extrinsic risk factors for CVDs in a high-risk population attending general practice in Jeddah, KSA. METHODS: We conducted a cross-sectional survey at King Abdulaziz University Hospital in Jeddah. Patients started on lipid-lowering and/or antihypertensive and/or antidiabetes treatments without a history of established cardiovascular disease were interviewed. The questionnaire was adopted from the EUROASPIRE III study. RESULTS: Two hundred and fifty high-risk individuals (80.0% female) were interviewed. Overall, 72% of the patients had been diagnosed with hypertension, 61.2% of patients had dyslipidemia, and approximately two-thirds of patients had diabetes mellitus. Most of the patients (88%) were non-smokers. The mean waist circumference of patients was 101.6 ± 14.1 cm, which suggests most were clinically obese. About 54.8% of the patients followed an unhealthy diet and 52.0% were physically inactive. There were significant differences between women and men in relation to dyslipidemia (p = 0.007), unhealthy diet (p = 0.034), being overweight (p = 0.018), and high blood cholesterol (p = 0.002). We observed significantly greater prevalence of hypertension (p = 0.073), unhealthy diet (p = 0.015), being overweight (p = 0.018), and high blood cholesterol (p = 0.000) in those patients with dyslipidemia. CONCLUSION: Our study presents novel findings in the KSA. Women were more likely to have high-risk CVD risk factors compared with their male counterparts in this sample. Gender-specific prevention programs in the KSA should be considered to more appropriately target at-risk individuals, to reduce preventable morbidity and mortality associated with CVDs.

RESUMEN

This policy analysis focuses on harnessing the power of artificial intelligence (AI) in hospital quality improvement to transform quality and patient safety. It examines the application of AI at the two following fundamental levels: (1) diagnostic and treatment and (2) clinical operations. AI applications in diagnostics directly impact patient care and safety. At the same time, AI indirectly influences patient safety at the clinical operations level by streamlining (1) operational efficiency, (2) risk assessment, (3) predictive analytics, (4) quality indicators reporting, and (5) staff training and education. The challenges and future perspectives of AI application in healthcare, encompassing technological, ethical, and other considerations, are also critically analyzed.

RESUMEN

The current study examined the longitudinal effects of clinical and treatment utilization factors on aggressive behavior among 376 help-seeking U.S. veterans recently diagnosed with posttraumatic stress disorder (PTSD) who were followed for 5-12 months. Participants were sampled from 4 strata: male Iraq/Afghanistan veterans, female Iraq/Afghanistan veterans, male prior-era veterans, and female prior-era veterans. Hierarchical regression analyses indicated that changes in PTSD severity were significantly associated with changes in aggressive behavior among veterans who reported any aggression at baseline (ß = .15). Changes in days of alcohol intoxication also were positively associated with changes in aggressive behavior (ß = .16). Participants with both a benzodiazepine prescription and any baseline aggression were significantly more likely to increase in aggressive behavior over time (ß = .14). Contrary to our hypotheses, reductions in aggressive behavior were not related to the number of outpatient mental health visits or to first-line recommended psychotropic medications. Results inform assessment and clinical research on changes in aggressive behavior among veterans with PTSD.

RESUMEN

OBJECTIVE: Cardiac rehabilitation (CR) is a comprehensive model of secondary preventive care. There is a wide variety in implementation characteristics globally, and hence quality control is paramount. Thus, the International Council of Cardiovascular Prevention and Rehabilitation was urged to develop a CR registry. The purpose of this study was to test the perceived usability of the International Cardiac Rehabilitation Registry (ICRR) to optimise it. DESIGN: This was a qualitative study, comprising virtual usability tests using a think-aloud method to elicit feedback on the ICRR, while end-users were entering patient data, followed by semistructured interviews. SETTING: Ultimately, 12 tests were conducted with CR staff (67% female) in low-resource settings from a variety of disciplines in all regions of the world but Europe before saturation was achieved. PRIMARY OUTCOME MEASURE: Participants completed the System Usability Scale. Interviews were transcribed verbatim except to preserve anonymity, and coded using NVIVO by two researchers independently. The Unified Theory of Acceptance and Use of Technology 2 informed analysis. RESULTS: The ICRR was established as easy to use, relevant, efficient, with easy learnability, operability, perceived usefulness, positive perceptions of output quality and high end-user satisfaction. System usability was 83.75, or 'excellent' and rated 'A'. Four major themes were deduced from the interviews: (1) ease of approvals, adoption and implementation; (2) benefits for programmes, (3) variables and their definitions, as well as (4) patient report and follow-up assessment. Based on participant observation and utterances, suggestions for changes to the ICRR were implemented, including to the programme survey, on-boarding processes, navigational instructions, inclusion of programme logos, direction on handling unavailable data and optimising data completeness, as well as policies for authorship and programme certification. CONCLUSIONS: With usability of the ICRR optimised, pilot testing shall ensue.

RESUMEN

BACKGROUND: Galangin, a bioactive flavonoid with remarkable antioxidant and anti-apoptotic actions, has demonstrated promising amelioration of experimental hepatotoxicity, cardiomyopathy, and colitis. Yet, its impact on cadmium-induced renal injury has not been explored. Herein, we aimed at exploring the potential of galangin to attenuate cadmium-induced nephrotoxicity in rats, focusing on oxidative stress, apoptosis, and autophagy. METHODOLOGY: Cadmium chloride (5 mg/kg/day) and galangin (15 mg/kg/day) were received by oral gavage and the kidney tissues were inspected using ELISA, biochemical measurements, histology, and immunohistochemistry. KEY FINDINGS: Galangin attenuated cadmium-induced renal damage by diminishing the histopathological alterations alongside KIM-1, BUN, and creatinine. At the molecular level, galangin attenuated the oxidative insult by significantly lowering the lipid peroxides and NOX-1 and augmenting GSH and GPx antioxidants. It also activated the cytoprotective SIRT1/Nrf2/HO-1 pathway by significantly upregulating the protein expression of SIRT1, Nrf2, and HO-1. Consistently, galangin suppressed renal apoptotic cell death by significantly lowering the protein expression of Bax and cytochrome C and activity of caspase-3 alongside upregulating the protein expression of the anti-apoptotic Bcl-2. Additionally, galangin activated the impaired autophagy flux as seen by diminishing the accumulation of SQSTM1/p62 and increasing the protein expression of Beclin 1. Meanwhile, galangin stimulated the autophagy-linked AMPK/mTOR pathway by significantly increasing the p-AMPK/total AMPK and lowering p-mTOR/total mTOR ratios. CONCLUSION: Galangin mitigated cadmium-induced nephrotoxicity thanks to its promising antioxidant, anti-apoptotic, and pro-autophagic effects. In perspective, galangin stimulated the SIRT1/Nrf2/HO-1 and AMPK/mTOR pathways. Hence, it may act as a complementary tool for the management of cadmium-induced renal injury.

RESUMEN

Colitis is one of the inflammatory states that affect the intestinal wall and may even predispose to malignancy due to chronic irritation. Although the etiology of colitis is not yet fully explored, a combination of genetic and environmental factors is strongly incriminated. Perindopril is an angiotensin-converting enzyme inhibitor that is used for the management of a wide range of cardiovascular diseases. Ambrosin is a sesquiterpene lactone that was proven to have beneficial effects in disorders characterized by inflammatory nature. The objective of this study is to make a comparison between the effects of perindopril or ambrosin on dextran sulfate sodium (DSS)-induced colitis in mice and to explore the effect of their combination. The present findings indicate that each ambrosin or perindopril alone or in combination is able to ameliorate oxidative stress and suppress the proinflammatory pathways in the colonic tissues of DSS-treated mice via mechanisms related to toll-like receptor 4/nuclear factor kappa B signaling and modulation of peroxisome proliferator-activated receptor gamma/sirtuin-1 levels. In addition, each ambrosin or perindopril alone or in combination inhibits apoptosis and augments the mediators of autophagy in DSS-treated mice. These effects are reflected in the amelioration of the histopathological and electron microscopic changes in the colonic tissues. Interestingly, the most remarkable effects are those encountered with the perindopril/ambrosin combination compared to the groups treated with each of these agents alone. In conclusion, the perindopril/ambrosin combination might represent an effective modality for mitigation of the pathogenic events and the clinical sequelae of colitis.

RESUMEN

Cadmium, a ubiquitous environmental toxicant, disrupts testicular function and fertility. The dipeptidyl peptidase-4 inhibitor linagliptin has shown pronounced anti-inflammatory and anti-apoptotic features; however, its effects against cadmium-evoked testicular impairment have not been examined. Herein, the present study investigated targeting inflammation, apoptosis, and autophagy by linagliptin for potential modulation of cadmium-induced testicular dysfunction in rats. After 60 days of cadmium chloride administration (5 mg/kg/day, by gavage), testes, epididymis, and blood were collected for analysis. The present findings revealed that linagliptin improved the histopathological lesions, including spermatogenesis impairment and germ cell loss. Moreover, it improved sperm count/motility and serum testosterone. The favorable effects of linagliptin were mediated by curbing testicular inflammation seen by dampening of HMGB1/TLR4 pathway and associated lowering of nuclear NF-κBp65. In tandem, linagliptin suppressed the activation of NLRP3 inflammasome/caspase 1 axis with consequent lowering of the pro-inflammatory IL-1ß and IL-18. Jointly, linagliptin attenuated testicular apoptotic responses seen by Bax downregulation, Bcl-2 upregulation, and suppressed caspase 3 activity. With respect to autophagy, linagliptin enhanced the testicular autophagy flux seen by lowered accumulation of p62 SQSTM1 alongside upregulation of Beclin 1. The observed autophagy stimulation was associated with elevated AMPK (Ser487) phosphorylation and lowered mTOR (Ser2448) phosphorylation, indicating AMPK/mTOR pathway activation. In conclusion, inhibition of testicular HMGB1/TLR4/NLRP3 pro-inflammatory axis and apoptosis alongside stimulation of autophagy were implicated in the favorable actions of linagliptin against cadmium-triggered testicular impairment.

RESUMEN

INTRODUCTION: Prolonged exposure therapy is an effective treatment for posttraumatic stress disorder that is underutilized in health systems, including the military health system. Organizational barriers to prolonged exposure implementation have been hypothesized but not systematically examined. This multisite project sought to identify barriers to increasing the use of prolonged exposure across eight military treatment facilities and describe potential solutions to addressing these barriers. MATERIALS AND METHODS: As part of a larger project to increase the use of prolonged exposure therapy in the military health system, we conducted a needs assessment at eight military treatment facilities. The needs assessment included analysis of clinic administrative data and a series of stakeholder interviews with behavioral health clinic providers, leadership, and support staff. Key barriers were matched with potential solutions using a rubric developed for this project. Identified facilitators, barriers, and potential solutions were summarized in a collaboratively developed implementation plan for increasing prolonged exposure therapy tailored to each site. RESULTS: There was a greater than anticipated consistency in the barriers reported by the sites, despite variation in the size and type of facility. The identified barriers were grouped into four categories: time-related barriers, provider-related barriers, barriers related to patient education and matching patients to providers, and scheduling-related barriers. Potential solutions to each barrier are described. CONCLUSIONS: The findings highlight the numerous organizational-level barriers to implementing evidence-based psychotherapy in the military health system and offer potential solutions that may be helpful in addressing the barriers.

RESUMEN

Stimuli-responsive temporary adhesives constitute a rapidly developing class of materials defined by the modulation of adhesion upon exposure to an external stimulus or stimuli. Engineering these materials to shift between two characteristic properties, strong adhesion and facile debonding, can be achieved through design strategies that target molecular functionalities. This perspective reviews the recent design and development of these materials, with a focus on the different stimuli that may initiate debonding. These stimuli include UV light, thermal energy, chemical triggers, and other potential triggers, such as mechanical force, sublimation, electromagnetism. The conclusion discusses the fundamental value of systematic investigations of the structure-property relationships within these materials and opportunities for unlocking novel functionalities in future versions of adhesives.

RESUMEN

BACKGROUND: A toe-extension movement pattern may contribute to metatarsophalangeal joint deformity and ulceration in people with diabetes. We sought to quantify the relationship between toe extension magnitude and variability during three functional tasks (ankle range of motion, sit to stand, walking) with metatarsophalangeal joint deformity, and identify potential mechanisms associated with a toe-extension movement pattern. METHODS: Individuals with diabetes and peripheral neuropathy were included (n = 60). Metatarsophalangeal joint deformity was assessed using computed tomography (CT). Toe-extension movement was quantified using 3-dimensional motion capture. Linear regression was used to investigate the role of toe-extension movement pattern on metatarsophalangeal joint deformity. Regression analysis was used to identify mechanisms (neuropathy severity, foot intrinsic muscle deterioration ratio, ankle dorsiflexion range of motion) contributing to toe-extension movement pattern. FINDINGS: Toe extension with each functional task as well as the mean and coefficient of variation across all tasks were significantly related to metatarsophalangeal joint deformity (range of correlation coefficients = (-0.386, 0.692), p ≤ 0.001). Ankle dorsiflexion range of motion was associated with mean toe extension across all tasks (rsp = -0.282, p = 0.029). Neuropathy severity and foot intrinsic muscle deterioration ratio were associated with toe extension variability (rsp = -0.373, p = 0.003 and rsp = -0.266, p = 0.043; respectively). INTERPRETATION: Greater magnitude and lower variability of a toe-extension movement pattern was found to be associated with metatarsophalangeal joint deformity. These findings may support clinical assessment and treatment of movement across more than one task.

RESUMEN

Intravenous cyclophosphamide is considered to be the standard of care for the treatment of proliferative lupus nephritis. However, its use is limited by potentially severe toxic effects. Cyclosporine A has been suggested to be an efficient and safe treatment alternative to cyclophosphamide. Forty patients with clinically active proliferative lupus nephritis were randomly assigned to one of two sequential induction and maintenance treatment regimens based either on cyclophosphamide or Cyclosporine A. The primary outcomes were remission (defined as normal urinary sediment, proteinuria <0.3 g/24 h, and stable s-creatinine) and response to therapy (defined as stable s-creatinine, 50% reduction in proteinuria, and either normalization of urinary sediment or significant improvement in C3) at the end of induction and maintenance phase. Secondary outcomes were incidence of adverse events, and relapse-free survival. At the end of the induction phase, 24% of the 21 patients treated by cyclophosphamide achieved remission, and 52% achieved response, as compared with 26% and 43%, respectively of the 19 patients treated by the Cyclosporine A. At the end of the maintenance phase, 14% of patients in cyclophosphamide group, and 37% in Cyclosporine A group had remission, and 38% and 58% respectively response. Treatment with Cyclosporine A was associated with transient increase in blood pressure and reversible decrease in glomerular filtration rate. There was no significant difference in median relapse-free survival. In conclusion, Cyclosporine A was as effective as cyclophosphamide in the trial of sequential induction and maintenance treatment in patients with proliferative lupus nephritis and preserved renal function.(ClinicalTrials.gov identifier: NCT00976300)

RESUMEN

OBJECTIVE: There is a need to determine whether total antioxidant capacity (TAC) in severe early childhood caries (S-ECC) is an indicator of inflammatory response to the lesion or a marker of the disease. This study compared TAC levels in children with ECC before and after dental treatment and compared the results with those of caries-free children. DESIGN: Prospective study. SETTING: A teaching hospital. PATIENT SELECTION: Salivary samples were obtained from 20 children aged 5 years and diagnosed with S-ECC, and 20 age- and sex-matched controls. INTERVENTION DETAILS: Complete dental rehabilitation under general anesthesia was performed on the children with S-ECC, and follow-up salivary samples were obtained one week and three months postoperatively. TAC was measured using a commercially available Oxygen Radical Absorbance Antioxidant Assay measurement kit (Zen-Bio ORAC™, AMS Biotechnology, Abington, UK). OUTCOME MEASURES: Differences between children with and without dental caries were tested using the Mann-Whitney U test; differences before and after dental treatment were analyzed using Friedman test followed by Wilcoxon sign-rank test with Bonferroni correction to compensate for multiple comparisons. RESULTS: Median TAC (1.54 mcg/L, CI 1.15-1.92) of the control group was significantly lower than that of the treated group prior to treatment (p = 0.003). Treatment of the dental lesions significantly reduced TAC of the treated group, and no significant differences were observed between the test and control groups at either one week (p = 0.076) recall or three-month recall (p = 0.096). TAC in children posttreatment was significantly reduced compared to their pretreatment values (p < 0.001). CONCLUSION: Total antioxidant capacity in the saliva of children with severe early childhood caries undergoes significant reduction following treatment of the carious lesions.

RESUMEN

Adults (N = 703) in Nairobi, Kenya completed a screening survey in the aftermath of the postelection violence (PEV) of 2008. This study examined associations between exposure to PEV, prior trauma exposure, religious coping, and psychiatric distress. Results indicated a dose-response effect of the amount of PEV and prior trauma exposure on the severity of concurrent symptoms of psychiatric distress. Over 90% of the sample reported a religious affiliation, and the majority of participants also reported frequent use of religious coping strategies. However, there was no significant effect for the use of turning to religion as a form of coping on psychiatric distress. Study results aligned with existing research on the dose-response, cumulative effect of frequent exposure to trauma. Further research can investigate the nuanced ways that community members use their religion to cope.

RESUMEN

BACKGROUND: Improper inhaler use results in decreased drug deposition in the lungs. The impact of health literacy and poor vision on the patient's ability to learn inhaler technique by reading instructions has not been confirmed. This study evaluated the effectiveness of learning inhaler technique from written instructions and the impact of health literacy for patients diagnosed with COPD who used a dry powder inhaler (DPI). METHODS: This pilot study recruited subjects diagnosed with COPD. A trained assessor scored subjects' inhaler technique before and after reading the appropriate American College of Chest Physicians handouts. Peak inspiratory flows (PIFs) were measured using an InCheck Dial. Health literacy was measured by the S-TOFHLA (Short Test of Functional Health Literacy in Adults), and visual acuity was measured by a Snellen chart. Associations between health literacy and visual acuity and changes in subjects' inhaler technique scores were assessed by Spearman's rho. Inhaler technique change scores were assessed by the Wilcoxon signed-rank test at P = .05. RESULTS: Of the 24 participants enrolled, 63% were female, mean age was 65.6 y, and 83% were Global Initiative for Chronic Obstructive Lung Disease air-flow limitation 2 or 3. Wilcoxon scores were significant for improved total scores for both the Diskus and HandiHaler, with medians improving from 6.5 to 7.0 (interquartile range 6.0-7.8) (P = .047) and from 6.0 to 7.5 (interquartile range 7.0-9.0) (P = .002), respectively. The minimum required PIF was achieved by 93.8% of the Diskus and 94.4% of the HandiHaler groups. There were no associations detected between the handout intervention (Diskus and HandiHaler) and health literacy level and vision. CONCLUSIONS: The educational handouts for DPIs helped participants already using a DPI to improve their inhaler technique. Stable participants diagnosed with COPD are able to generate appropriate PIFs to properly use DPIs. Neither vision nor health literacy was associated with the inability to learn inhaler technique from patient education inhaler device handouts.

RESUMEN

The prevalence of HLA-B27 in the general population and in axial spondyloarthritis (axSpA) patients in Saudi Arabia is unknown. The aim of this study was to evaluate the prevalence of HLA-B27 in these two populations and describe the delay in diagnosis of axSpA patients. The prevalence of HLA-B27 in the general population was evaluated using cord blood and healthy organ transplant donor databases. Data from patients with axSpA were collected retrospectively from five centers. Ankylosing spondylitis (AS) was diagnosed based on a positive X-ray, as evaluated by two independent readers. Patients with inflammatory bowel disease and psoriasis were excluded. A total of 134 axSpA patients were included, of whom 107 (79.9%) had AS, and most (67.2%) were males. HLA-B27 was positive in 60.4, 69, and 25.9% of patients with axSpA, AS, and non-radiographic axSpA (nr-axSpA), respectively. The median and interquartile range (IQR) ages at symptom onset and disease diagnosis were 26 (20-33) and 30 (25-38) years, respectively. The median delay to diagnosis was 3 (1-6) years. There was a negative correlation between the time of onset of symptoms and the delay in diagnosis (r = -0.587). Male gender and HLA-B27 positivity were associated with a younger age at symptom onset/diagnosis (p < 0.05). HLA-B27 was positive in 82/3332 (2.5%) and 27/1164 (2.3%) individuals in the cord blood and healthy organ transplant donor databases, respectively. The prevalence of HLA-B27 is lower in the general Saudi population and in axSpA patients compared to Caucasians, thus, limiting its utility as a diagnostic criterion.

RESUMEN

Schizosaccharomyces pombe is an outstanding model organism for cell biological investigations, yet the range of useful and well-characterized fluorescent proteins (XFPs) is limited. We generated and characterized three recoded fluorescent proteins for 3-color analysis in S.pombe, Super-folder GFP, monomeric Kusabira Orange 2 and E2Crimson. Upon optimization and expression in S. pombe, the three proteins enabled sensitive simultaneous 3-color detection capability. Furthermore, we describe a strategy that combines a pulse-chase approach and mathematical modeling to quantify the maturation kinetics of these proteins in vivo. We observed maturation kinetics in S. pombe that are expected from those described for these proteins in vitro and/or in other cell types, but also unpredicted behaviors. Our studies provide a kinetically-characterized, integrated three-color XFP toolbox for S. pombe.

RESUMEN

Many theories have surfaced regarding the exact mechanisms behind glaucomatous damage, but the complex nature of the disease and the inaccessibility of the internal structures of the human eye have limited current knowledge. Increased intraocular pressure is the risk factor most often associated with glaucomatous optic neuropathy; ischemic insult to the optic nerve has also been suggested as a possible cause of cellular damage. The aim of this review is to cover the possible role of optic nerve head hemodynamics in the pathogenesis of glaucoma.
