Purpose: To describe the characteristics and recurrence rates of primary periocular squamous cell carcinoma (SCC) in Spain. Methods: This retrospective study investigates the characteristics of primary periocular SCC at two tertiary centers in Spain from 2000 to 2020. Data were collected on demographics, skin phenotype, location, clinical and histological diagnosis, the commitment of surgical margins, recurrence, and risk factors. Multivariate analysis and risk factors were used to investigate recurrence rates, considering p < 0.05 as statistically significant. Results: Over the 20-year studied period, 107 patients with primary periocular SCC were assessed. The mean age of SCC was 76.8 ± 12.8 years, 55 (50.9%) were females, and 105 (98.1%) had Fitzpatrick skin phenotype type II or III. SCC lesions affected less than 1/3 of the eyelid (56/52.3% cases), mainly the lower lid (42/39.3% lesions). Sixty (56.1%) cases were SCC differentiated, 76 (71%) had clear margins. Clinical diagnosis of SCC corroborated with histological in 84 (78.5%) cases and orbital involvement occurred in 18 (16.8%) cases. Recurrence was observed in 13 (12.1%) cases, occurring more in large tumors and undifferentiated subtype (53.8%), with committed margins (69.2%) ( p = 0.001), being the commitment of margins a significant predictor for recurrence, although thickness was an independent predictor. Conclusion: Periocular SCC in Spain showed a similar pattern as in the world. The risk of recurrence is increased in undifferentiated and large periocular SCC, partially removed with committed margins.

Published: July 2021

One new case of dementia is detected every 4 seconds and no effective drug therapy exists. Effective behavioural strategies to promote healthy cognitive ageing are thus essential. Three behaviours related to cognitive health which we all engage in daily are physical activity, sedentary behaviour and sleep. These time-use activity behaviours are linked to cognitive health in a complex and dynamic relationship not yet fully elucidated. Understanding how each of these behaviours is related to each other and cognitive health will help determine the most practical and effective lifestyle strategies for promoting healthy cognitive ageing. In this review, we discuss methods and analytical approaches to best investigate how these time-use activity behaviours are related to cognitive health. We highlight four key recommendations for examining these relationships such that researchers should include measures which (1) are psychometrically appropriate; (2) can specifically answer the research question; (3) include objective and subjective estimates of the behaviour and (4) choose an analytical method for modelling the relationships of time-use activity behaviours with cognitive health which is appropriate for their research question.

Published: July 2021

Introduction A survey of International Federation of Societies for Hand Therapy (IFSHT) member countries identified relative motion extension as the preferred approach to management of zones V-VI extensor tendon repairs. The aims of this survey were to identify and compare hand therapy practice patterns in Malaysia (a non-IFSHT member country) with findings of the IFSHT survey including an IFSHT subset of Asia-Pacific therapists and to investigate if membership status of the Malaysian Society for Hand Therapists (MSHT) influenced therapy practice patterns. Methods An online English-language survey was distributed to 90 occupational therapists and physiotherapists including MSHT members and non-members. Participation required management of at least one extensor tendon repair in the preceding year. Five approaches were surveyed: immobilisation, early passive motion (EPM) with dynamic splinting, and early active motion (EAM) delivered by resting hand (RH), palmar resting interphalangeal joints free (PR), and relative motion extension (RME) splints. Results Thirty-seven of the 53 therapists (68%) who commenced the survey completed it. The most used approach was dynamic/EPM (28%), followed by RH/immobilisation (22%) and RH/EAM (22%). A preference for RME/EAM was identified with implementation barriers being surgeon preference and hand therapist confidence. Discussion Approach selection for Malaysian therapists differed from the combined IFSHT and Asia-Pacific respondents, with the former using dynamic/EPM and RH/immobilisation compared to IFSHT respondents who predominately used RME/EAM and PR/EAM. This survey provides valuable insights into Malaysian hand therapists’ practices. If implementation barriers and therapist confidence are addressed, Malaysian practice patterns may change to better align with current evidence.
Confronting Forensic Pathologists
Authors: Weedn Victor W. 
Published: July 2021

Background: The Sixth Amendment Confrontation Clause gives defendants a right to confront their accusers. Method: U.S. Supreme Court cases that interpreted this right as applied to forensic scientists were reviewed. Results: Melendez-Diaz, Bullcoming, and Williams examined constitutional rights to confront forensic scientists. Lower courts have specifically examined their application to forensic pathology. Whether autopsy reports are considered “testimonial” varies among jurisdictions and has not been definitively settled. Defendants are generally able to compel testimony of forensic pathologists. Where the forensic pathologist is truly unavailable, the surrogate expert should be in a position to render an independent opinion.
Leaf Nutrient Relations of Cycads in a Common Garden
Authors: Marler Thomas E. , Lindström Anders J. 
Published: July 2021

Background and Aims Research required to clarify leaf nutrient relations of cycad species has been inadequate. Common garden studies are useful for determining the influence of genetics on leaf traits because of the homogeneous environment among experimental units. To date, there have been no common garden studies which included all ten genera of cycads. The full phylogenetic breadth has, therefore, not been included in this important area of study. Methods We examined macronutrient and micronutrient content of leaves from one representative species from each of the ten cycad genera at Nong Nooch Tropical Botanical Garden in Thailand. Nitrogen content was determined by dry combustion, and the remaining nutrients were quantified by spectrometry. Results The least variable elements were nitrogen and phosphorus, and the most variable elements were boron and sodium. Nutrient content based on leaflet area was more variable than based on leaflet mass, reflecting species differences in specific leaf area. There were no universal macronutrient or micronutrient signals indicating clear phylogenetic distinctions. Implications for Conservation: Active management of threatened cycad taxa requires research to develop the knowledge to enable evidence-based decisions. This common garden study inclusive of all 10 cycad genera creates a foundation to determine leaf nutrient sufficiency ranges to inform management decisions.

Background: Daratumumab (Dara) is generally well tolerated, but is associated with increased risk of infection. Methods: We investigated hypogammaglobinemia occurrence in different Dara-based regimens. Multiple myeloma (MM) patients were treated with ⩾2 cycles of Dara-based therapy during 2016–2020, mainly for relapsed/refractory disease. Data on patient characteristics, treatment regimens, polyclonal IgG (poly-IgG) and uninvolved free light chain (Un-FLC) levels during treatment, as well as predictors for hypogammaglobinemia and predictors for infections, were evaluated retrospectively. Results: A total of 84 patients, median age 67.2 years, were included. Dara, mainly as ⩾2 line therapy (88.1%, n = 74), was combined with immunomodulating drugs (IMiDs) (53%), proteasome inhibitors (PIs) (15%), IMiDs-PIs (11%), or dexamethasone only (21%). Median treatment duration was 13 months. Median Poly-IgG levels at 0, 2, and 4 months were 7.1 g/l, 4.5 g/l, and 4 g/l, respectively, and remained low throughout treatment. Lower poly-IgG pre-Dara ( p = 0.001) and Dara-PIs (±IMiDs) regimen were associated with lower poly-IgG levels at 4 months ( p = 0.03). Only patients treated with Dara monotherapy had partial immune reconstitution, reflected by resumption of IgM levels. Most (85%) patients developed ⩾1 infections, mostly grade 1–2 respiratory (76%). A lower poly-IgG level post Dara (RR = 1.137 p = 0.026) predicted increased risk of any infection. Intravenous immunoglobulin (IVIG) was associated with a significant decrease in all infections. Conclusion: Relapsed MM patients treated with Dara, often experience persistent hypogammaglobinemia, irrespective of responsiveness to treatment. Infections, especially respiratory, are frequent and apparently related to low Poly-IgG levels. IVIG should be considered for reducing infections in these patients.

Study Design: Retrospective cohort study. Objective: The influence that race has on mortality rates in patients with spinal cord tumors is relatively unknown. The aim of this study was to investigate the influence of race on the outcomes of patients with primary malignant or nonmalignant tumors of the spinal cord or spinal meninges. Methods: The Surveillance, Epidemiology, and End Results (SEER) Registry was used to identify all patients with a code for primary malignant or nonmalignant tumor of the spinal cord (C72.0) or spinal meninges (C70.1) from 1973 through 2016. Racial groups (African-American/Black vs. White) were balanced using propensity-score (PS) matching using a non-parsimonious 1:1 nearest neighbor matching algorithm. Overall survival (OS) estimates were obtained using the Kaplan-Meier method and compared across non-PS-matched and PS-matched groups using log-rank tests. Associations of survival with clinical variables was assessed using doubly robust Cox proportional-hazards (CPH) regression analysis. Results: There were a total of 7,498 patients identified with 648 (6.8%) being African American. African-American patients with primary intradural spine tumors were more likely to die of all causes than were White patients in both the non-PS-matched [HR: 1.26, 95% CI: (1.04, 1.51), P = 0.01] and PS-matched cohorts [HR: 1.64, 95% CI: (1.28, 2.11), P < 0.0001]. On multivariate CPH regression analysis age at diagnosis [HR: 1.03, 95% CI: (1.02, 1.05), P < 0.0001], race [HR: 1.82, 95% CI: (1.22, 2.74), P = 0.004), and receipt of RT [HR: 2.62, 95% CI: (1.56, 4.37), P = 0.0002) were all significantly associated with all-cause mortality, when controlling for other demographic, tumor, and treatment variables. Conclusions: Our study provides population-based estimates of the prognosis for patients with primary malignant or nonmalignant tumors of the spinal cord or spinal meninges and suggests that race may impact all-cause mortality.

Published: July 2021

Purpose: This work describes the clinical management and outcomes in cases of presumed infectious endophthalmitis following intravitreal injection at a tertiary academic medical center. Methods: A retrospective review took place of eyes that presented to the Duke Eye Center over a 9-year period and were diagnosed with intravitreal injection–related endophthalmitis. Clinical presentation, management, microbiologic yield, visual outcomes, and complications were abstracted from medical records. Results: Of 23 eyes diagnosed with postinjection endophthalmitis, 52.2% underwent anterior chamber tap (33.3% of which first underwent dry needle vitreous tap), 47.8% underwent needle vitreous tap, 17.4% underwent neither, and none underwent pars plana vitrectomy (PPV) for initial management. Subsequent PPV was performed in 6 eyes (26.1%). Mean visual acuity (VA) improved by 50 Early Treatment Diabetic Retinopathy Study letters at 6 months. Eyes that underwent initial anterior chamber tap had worse presenting VA than those that did not ( P = .01). Eyes undergoing subsequent PPV had worse VA at presentation ( P = .02) and at 6 months ( P < .001). Eyes presenting with VA of hand motion (20/8000) or worse were more likely to undergo subsequent PPV ( P = .02). Conclusions: Eyes with intravitreal injection–related endophthalmitis presenting with VA of hand motion or worse were more likely to undergo subsequent PPV. Future studies with larger cohorts may reveal whether earlier vitrectomy should be considered in these patients.

Abstract
Background
Retinitis pigmentosa (RP) is a heterogeneous group of inherited ocular diseases that result in progressive retinal degeneration. This study aims to describe different Swept-source Optical Coherence Tomographic (SS-OCT) changes in Palestinian RP patients and to explore possible correlations with Visual Acuity (VA).

Methods
A cross-sectional observational study was conducted on Retinitis Pigmentosa patients diagnosed with RP in a tertiary eye hospital. Full history and ocular examination were made. SS-OCT imaging was done for all eyes assessing the presence of cystoid macular edema, epiretinal membrane, macular holes, and external limiting membrane, ellipsoid zone status. Also, central macular thickness and choroidal vascular thickness were measured.

Results
The study was run on 161 eyes of 81 patients; 53 males and 28 females. The average age at examination was 26.1 (6–78) years. Twenty-six eyes (16.1%) were of syndromic RP patients, mostly Usher syndrome; 20 eyes (12.4%). The mean Logaritmic minimal angle of resolution (LogMAR) of Best Corrected Visual Acuity (BCVA)of the study sample was 0.66 ± 0.7. The most prevalent change was cystoid macular edema [28 eyes, (17.4%)], followed by epiretinal membrane [17eye, (10.6%)]. A macular hole was noted only in one eye (0.6%). Ellipsoid zone and external limiting membrane were absent in 55 eyes (35.0%) and 60 eyes 37.5%. Vitreous hyperreflective foci were found in 35 eyes (43.8%). LogMAR of BCVA was associated significantly with cystoid macular edema (p = 0.001), ellipsoid zone(p = 0.001), and external limiting membrane (p = 0.001).

Conclusions
Detailed SS-OCT assessment in Palestinian patients diagnosed with RP identified different morphologies from other populations. Cystoid macular edema and vitreous hyperreflective foci may reflect signs of early or intermediate stages of the disease. Disease progression can be monitored by measuring the length/width (area) of ellipsoid zone +/− external limiting membrane and choroidal vascular thickness, which should be evaluated serially using high-resolution OCT.

Abstract
Background
Brief behavioral interventions are seen as an efficient way to improve knowledge, change behavior, and reduce provider stigma regarding sexual health. When grounded in evidence-based behavioral change techniques and delivered using Brief Sexuality-related Communication (BSC) tools, brief behavioral interventions can address client-driven sexual health goals in a single session with their provider. Evidence for the efficacy of brief interventions for creating gains in sexual health comes largely from resource rich settings, and there is a lack of knowledge of how brief interventions can be implemented in the more resource constrained environments of low- and middle-income countries. As a first step in developing a brief intervention to address sexual health issues in Moldova, this paper reports on qualitative data collected from Moldovan providers to understand their attitudes, willingness and perceived barriers to the brief intervention and its implementation.

Methods
Thirty-nine in-depth interviews (IDI) were conducted between February and March 2020, with health providers recruited from three primary health care institutions, two Youth Friendly Health Centers and counselors from three NGOs who work with key populations in Moldova, including health centers selected from two cites - the capital city, Chisinau and from the Comrat Region. The IDI addressed four domains of provider attitudes: 1) attitudes towards the intervention; 2) willingness and motivation to implement the intervention; 3) logistics of providing the intervention and 4) ability to implement the intervention. A coding analysis approach was applied to all interview transcripts.

Results
Providers largely reported being willing to be trained in and implement the brief intervention. Willingness to implement the intervention stemmed from two perceptions: that it would improve the ability of providers to talk with their clients about sex, and that vulnerable groups would benefit from these conversations. However, while there were generally positive attitudes towards the intervention, providers consistently reported structural barriers to their perceived ability to implement the intervention.

Conclusions
While providers reported high levels of initial acceptance of a brief behavioral intervention, care is needed to ensure that brief interventions, and the training of providers on brief interventions, incorporate cultural attitudes and norms around sex, particularly in highly patriarchal settings, and provide opportunities for providers to practice the intervention in ways that address their assumptions and implicit biases.

Abstract
Background
Age-related hearing impairment (ARHI) has attracted increasing attention recently. It is caused by genetic and environmental factors. A number of ARHI-related genes have been found. This study aimed to detect the potential association between NR3C1 gene polymorphisms and ARHI by means of weighted allele score.

Methods
A total of 861 participants from Qingdao city were selected by means of cluster random sampling. We statistically evaluated the characteristics of individuals and used the Mann–Whitney U test or chi-square test for comparison. The publicly available expression quantitative trait locus (eQTL) was queried on the website of the Genotype-Tissue Expression (GTEx). We used the weighted allele score and logistic regression analysis to explore the association between NR3C1 gene polymorphisms and ARHI. Finally, the prediction model was constructed by logistic regression and receiver operating characteristic (ROC) curve.

Results
All individuals over 60 years of age were enrolled in this study. The allele of rs61757411, rs41423247 and rs6877893 were significantly different between the ARHI group and the normal hearing group (P < 0.01). Though eQTL analysis, rs6877893 and rs33388 might affect the occurrence of ARHI by affecting the expression of NR3C1 gene in artery aorta. Then we performed two models: one without adding any covariates into model and the other adjusting for demographic characteristic, smoking and drinking, diet and exercise, and physical conditions. In the multivariate-adjusted model 2, the odds ratio with 95% confidence interval for weighted allele score (NR3C1) was 0.841 (0.710–0.995, P = 0.043). The area under the ROC curve was 0.755, indicating that the model had good predictability.

Conclusions
Our study suggests that NR3C1 gene polymorphisms was significantly associated with ARHI.
