Is it time for PET-guided therapy in follicular lymphoma?
Authors: Trotman Judith , Pettitt Andrew R. 
Published: July 2021

Abstract
18F-fluorodeoxyglucose positron emission tomography-computed tomography (PET-CT) is now established as the gold-standard imaging modality for both staging and response assessment in follicular lymphoma (FL). In this Perspective, we propose where PET can, and cannot, guide clinicians in their therapeutic approach. PET at diagnosis and pretreatment is important for staging, with greater sensitivity compared with standard CT, and consequent improved outcomes in truly limited-stage FL. Small data sets suggesting that a high baseline standardized uptake value (SUVmax) identifies de novo histologic transformation (HT) have not been corroborated by data from GALLIUM, the largest prospective study to examine modern therapies for FL. Nonetheless, the role of baseline quantitative PET measures requires further clarification. The median survival of patients with newly diagnosed FL is now potentially &gt;20 years. Treatment of symptomatic FL aims to achieve remission and optimize quality of life for as long as possible, with many patients achieving a “functional cure” at the cost of unwanted treatment effects. Several studies have identified end-of-induction (EOI) PET after initial chemoimmunotherapy in patients with a high tumor burden as strongly predictive of both progression-free and overall survival, and EOI PET is being evaluated as a platform for response-adapted treatment. Unmet needs remain: improving the inferior survival for patients remaining PET positive and quantifying the progression-free survival and time to next treatment advantage, and additional toxicity of anti-CD20 maintenance in patients who achieve complete metabolic remission. In the absence of an overall survival advantage for frontline antibody maintenance, the question of using PET to guide the therapeutic approach is more important than ever in the context of the COVID-19 pandemic.

Published: July 2021

BackgroundAsthma exacerbations in children is one of the most common medical conditions requiring urgent visits to primary healthcare providers or emergency departments, and even hospitalisations. Currently, there is significant variation in the management of asthma exacerbations expressed in guideline recommendationsversusclinical practice. This disconnect affects diagnostic and treatment decisions for the clinician and patient.ObjectiveWe systematically reviewed the available guidelines providing recommendations for diagnostic and therapeutic management of asthma exacerbations in the paediatric population.MethodsA systematic review of the literature for guidelines published between January 2009 and October 2019 was conducted, using a protocol registered with the international prospective register of systematic reviews (PROSPERO CRD42020221562).Results16 asthma exacerbation clinical practice guidelines for children were included. Despite general agreement between guidelines on the definition of asthma exacerbation, there was great variability in the definition of disease severity and assessment of asthma control. This systematic review also highlighted a paucity of recommendations for criteria for hospitalisation and discharge. Many guidelines scored poorly when measured for stakeholder involvement and editorial independence.ConclusionComprehensive and updated guidelines compliant with international standards for clinical guidelines may significantly improve clinical practice quality, promote evidence-based recommendations and provide uniformity of treatment between countries.

Abstract
Background
During the last decades, the abuse of anabolic androgenic steroids (AASs) has become popular among professional and recreational athletes. The abuse of AASs leads to decreased levels of sex hormones, but the available literature a gives very small pool of data regarding the effects of swimming alone or combined with AASs on testicle tissue. The aim of this study was to investigate the effects of four-week administration of nandrolone decanoate and swimming training alone or in combination on morphometric parameters, androgen receptor (AR) and redox state in testicle tissue. The study included Wistar albino male rats, 10 weeks old, classified into 4 groups: control (T-N-), nandrolone (T-N+), swimming training (T+N-) and swimming training with nandrolone (T+N+). The rats from nandrolone (N+) groups received nandrolone decanoate 20 mg/kg b.w.once per week. The rats from training (T+) groups, swam 1 h/day 5 days/week. The isolated testicles were measured, left testicles were routinely processed for histological analysis, while right testicles were homogenized and prepared for the analysis of the following oxidative stress biomarkers: index of lipid peroxidation (TBARS), nitrites, catalase, superoxide dismutase (SOD), and reduced glutathione (GSH).

Results
Diameter, as well as cross-section area of seminiferous tubules were decreased by 10 % and 21 % (respectively) in the T-N+ group and by 15% and 41 % (respectively) in the T+N+ group compared to control. Interstitium of the testicles was decreased in all experimental groups. Reduction of immunoreactivity of AR in T-N+ group was 22 %, in T+N+ group was 9 % compared to control. TBARS levels were increased in T+N- and T+N+ groups. Nitrites were decreased in T+N+ group. Catalase activity was increased in all experimental groups. Swimming alone or combined with nandrolone decreased the level of GSH compared to control. SOD activity was decreased in T-N+ and T+N+ groups compared to control.

Conclusions
Nandrolone alone or combined with swimming decreased morphometric parameters and amount of AR in testicle tissue. Changes in the redox state indicate reproductive dysfunction.

Abstract
Background
Cancer-related fatigue (CRF) is one of the most common and distressing symptoms in people with cancer. Although efficacy of interventions for CRF have been extensively investigated, less has been done to ensure successful translation into routine clinical practice. The aim of this systematic scoping review was to synthesise knowledge surrounding the implementation of CRF interventions, summarise the processes and outcomes of implementation strategies used, and identify opportunities for further research.

Methods
PubMed, Cochrane CENTRAL, EMBASE and CINAHL databases were searched (up to December 2020). The Cochrane Effective Practice and Organisation of Care (EPOC) Group taxonomy and the RE-AIM Framework were used to guide the evaluation of implementation strategies and outcomes, respectively.

Results
Six studies were included. Three used an implementation framework (PARIHS, KTA, Cullens & Adams’ Implementation Guide) to guide implementation. Overall, the implementation strategies used across all studies were reported to have directly resulted in immediate changes at the clinician level (e.g., increased clinician behaviours, self-efficacy, attitudes, knowledge of CRF management). No clear relationship was found between the use of implementation models and the number or type of implementation strategies used. For outcomes, Effectiveness and Implementation were the most highly reported RE-AIM measures followed by Reach then Maintenance. Adoption was the least reported.

Conclusions
Despite the high prevalence of CRF and evidence-based interventions for managing CRF, there is limited evidence informing the sustainable implementation of these interventions. This systematic scoping review emphasises the lack of quality CRF implementation studies presently available in the literature leading to a disconnect between effective CRF interventions, routine clinical care, and cancer survivors at present. This review highlights the need for robust study designs guided by established frameworks to methodically design and evaluate the implementation of CRF management interventions in the future.
Predicting the onset of myopia in children: results from the CLEERE study
Authors: Mutti Donald O. , Jordan Lisa A. , Zadnik Karla 
Published: July 2021

AbstractResearch often attempts to identify risk factors associated with prevalent disease or that change the probability of developing disease. These factors may also help in predicting which individuals may go on to develop the condition of interest. However, risk factors may not always serve as the best predictive factors and not all predictive factors should be considered as risk factors. A child’s current refractive error, parental history of myopia, and the amount of time children spend outdoors are excellent examples. Parental myopia and time outdoors are meaningful risk factors because they alter the probability of developing myopia and point to important hereditary and environmental influences. A child’s current refractive error points to no particular mechanism and is therefore a poor risk factor. However, it serves as an excellent predictive factor for identifying children likely to develop future myopia. Risk factors may explain how a child reached a particular level of refractive error, but knowledge of that history may not be needed in order to make an accurate prediction about future refractive error. Current refractive error alone may be sufficient. This difference between risk factors and predictive factors is not always appreciated in the literature, including a recent publication in BMC Ophthalmology. This letter attempts to make that distinction and to explain why parental myopia and time outdoors are significant risk factors in the Collaborative Longitudinal Evaluation of Ethnicity and Refractive Error, yet are not significant for predicting future myopia in a multivariate model that contains current refractive error.

Published: July 2021

Abstract
Background
Eczema is usually the first allergic manifestation to appear in life attributed to gene–environment interactions. IL13, IL4, MS4A2 and ILR4A are four key inflammatory genes associated with atopy. This study aimed to explore gene-environment interactions on eczema in early life among the above four genes and environmental factors in Chinese Han children.

Methods
Five hundred ninety-seven children from a birth cohort who completed two-year follow-up were enrolled and their cord blood was collected. Subjects were genotyped for six polymorphisms in the aforementioned four genes. The children were followed at 6, 12 and 24 months, with epidemiologic information and medical history of eczema collected by questionnaire and eczema assessed by dermatologists.

Results
Among the 597 children, 168 were diagnosed with eczema and the others were not after 2 years of follow-up. MS4A2 rs569108 GG genotype (P = 1.68E-02, odds ratio (OR) = 4.66) and antibiotic use (P = 3.75E-4, OR = 2.02) were found independently associated with development of childhood eczema. Children with both antibiotic use and MS4A2 rs569108 GG genotype were more likely to develop eczema than those with only antibiotic use or GG homozygote (OR = 6.24 VS. 2.04 or 4.68).

Conclusions
MS4A2 rs569108 polymorphism and antibiotic use were solely associated with eczema, and they interacted with each other to increase the risk of developing the disease in Chinese Han toddlers. Long-term follow-up along with functional and replication studies are still needed.

AbstractBackgroundTransgender women in the United States (U.S.) experience a disproportionate burden of HIV infection and challenges to engagement in HIV prevention and care. This excess burden is driven by structural and economic inequities. Microeconomic interventions may be effective strategies for reducing HIV inequities for this population. However, few studies have explored transgender women’s preferences for microeconomic interventions to address structural determinants of HIV vulnerability.MethodsWe conducted individual interviews with 19 adult transgender women in 2 U.S. cities (Richmond, VA and St. Louis, MO) who reported one or more sexual risk behaviors and recent economic hardship related to employment/income, housing, or food security. Interviews were recorded, transcribed, and analyzed using thematic content analysis.ResultsThe majority (74%) of transgender women were racial/ethnic minorities with mean age of 26.3 years. 89% were currently economically vulnerable; and 23% were employed full-time. 37% reported living with HIV. Participants expressed strong support for unrestricted vouchers, with many expressing the need for funds to support gender-affirming interventions. Assistance with how to budget and save and support for job acquisition, career planning, and employment sustainment were also preferred, including access to non-stigmatizing employment. Visible transgender leadership, group empowerment, and small (rather than large) numbers of participants were considered important aspects of intervention design for transgender women, including outreach through existing transgender networks to facilitate inclusion. Incorporating HIV counseling and testing to reduce vulnerability to HIV was acceptable. However, transgender women enrolled in the study preferred that HIV not be the focus of an intervention.ConclusionsFlexible microeconomic interventions that support gender affirming interventions, improve financial literacy, and provide living-wage non-stigmatizing employment are desired by economically vulnerable transgender women. While not focused on HIV, such interventions have the potential to reduce the structural drivers of HIV vulnerability among transgender women.

Published: July 2021

Abstract
Background
Secondary polycythemia is associated with cigarette smoking and chronic obstructive pulmonary disease (COPD). However, the prevalence of polycythemia in COPD and the contributing risk factors for polycythemia in COPD have not been extensively studied.

Methods
We analyzed the presence of secondary polycythemia in current and former smokers with moderate to very severe COPD at the five-year follow-up visit in the observational COPDGene study. We used logistic regression to evaluate the association of polycythemia with age, sex, race, altitude, current smoking status, spirometry, diffusing capacity for carbon monoxide (DLCO), quantitative chest CT measurements (including emphysema, airway wall thickness, and pulmonary artery to aorta diameter ratio), resting hypoxemia, exercise-induced hypoxemia, and long-term oxygen therapy.

Results
In a total of 1928 COPDGene participants with moderate to very severe COPD, secondary polycythemia was found in 97 (9.2%) male and 31 (3.5%) female participants. In a multivariable logistic model, severe resting hypoxemia (OR 3.50, 95% CI 1.41–8.66), impaired DLCO (OR 1.28 for each 10-percent decrease in DLCO % predicted, CI 1.09–1.49), male sex (OR 3.60, CI 2.20–5.90), non-Hispanic white race (OR 3.33, CI 1.71–6.50), current smoking (OR 2.55, CI 1.49–4.38), and enrollment in the Denver clinical center (OR 4.42, CI 2.38–8.21) were associated with higher risk for polycythemia. In addition, continuous (OR 0.13, CI 0.05–0.35) and nocturnal (OR 0.46, CI 0.21–0.97) supplemental oxygen were associated with lower risk for polycythemia. Results were similar after excluding participants with anemia and participants enrolled at the Denver clinical center.

Conclusions
In a large cohort of individuals with moderate to very severe COPD, male sex, current smoking, enrollment at the Denver clinical center, impaired DLCO, and severe hypoxemia were associated with increased risk for secondary polycythemia. Continuous or nocturnal supplemental oxygen use were associated with decreased risk for polycythemia.

Published: July 2021

Abstract
Background
The risk factors for postoperative complications after pulmonary resection in patients with non-small cell lung cancer (NSCLC) have not been elucidated.

Methods
Clinical data of 956 patients with NSCLC were analyzed. Patient factors such as sex, age, comorbidities, smoking history, respiratory function, and the lobe involved in lung cancer and operative factors such as operative approach and operative procedures were collected and analyzed.

Results
Male sex (odds ratio [OR]: 1.73, 95% confidence interval [CI]: 1.09–2.75, p = 0.01), coexistence of asthma (OR 2.68, 95% CI 1.19–6.02, p = 0.01), low percentage of forced expiratory volume in 1 s (FEV1) (OR 1.41, 95% CI 1.02–1.95, p = 0.03), and lobectomy or greater resection (OR 2.47, 95% CI 1.66–3.68, p < 0.01) were identified as significant risk factors for postoperative complications. Male sex (OR 1.98; 95% CI 1.03–3.81, p = 0.03) and complete video-assisted thoracic surgery and robot-assisted thoracic surgery (OR 1.64; 95% CI 1.09–2.45; p = 0.01) were identified as significant risk factors for postoperative air leakage. Coexistence of asthma (OR 9.97; 95% CI 3.66–27.38; p < 0.01) was identified as a significant risk factor for postoperative atelectasis or pneumonia. Lobectomy or greater resection (OR 19.71; 95% CI 2.70–143.57; p < 0.01) was identified as a significant risk factor for postoperative arrhythmia.

Conclusion
Male sex, coexistence of asthma, low percentage of FEV1, and operative procedure were significant risk factors for postoperative complications. Furthermore, risk factors varied according to postoperative complications.

Published: July 2021

AbstractThis commentary describes the unusual self-portrait contributed by a 26-year-old receiving treatment for relapsing medulloblastoma to a photography project undertaken by a group of patients as part of the Youth Project, a scheme dedicated to young cancer patients with the dual aim of optimizing medical aspects of their care and promoting a holistic approach to their needs. The article briefly describes how creative projects can play an important part in giving young people with cancer new ways to tell their stories and express their feelings. There is still a limited understanding of the specific needs of adolescents and young adults with cancer, and it is important to draw attention to them and to the need to devise a person-centered approach to cancer patients in this age group.

Abstract
Background
Our current study aimed to evaluate the effect of an Glechoma hederacea extract (Hitrechol®) in normal rats and gallstone diseased mice to explore its underlying mechanisms. Normal rats and C57BL/6 mice with/without cholesterol gallstone were used in this study.

Methods
To monitor the effect of Hitrechol® on bile secretion, bile flow rates at 15 min interval until 2 h post-dosing in normal rats treated with vehicle and Hitrechol® were compared using multiple t-test with a p < 0.05 considered as statistically significant different. To further evaluate the effect of Hitrechol® against the development of gallstone in lithogenic diet treated mice, mice were treated with vehicle or Hitrechol® (QD-once daily or TID-three times daily) for 3 weeks followed by comparing the levels of bile composition among the treatment groups. In addition, the anti-oxidative biomarkers in liver and anti-inflammatory biomarkers in serum were detected and compared among all the treatment groups to evaluate the hepato-protective effect of Hitrechol®. The obtained levels of biomarkers and bile composition were compared among different treatment groups using one-way ANOVA tests followed by Tukey’s multiple comparisons with p < 0.05 considered as statistically significant.

Results
Despite no significant impact on the bile flow rate, Hitrechol® TID treatment dramatically decreased size and amount of gallstone crystals and total cholesterol level (p < 0.05), as well as total bile acid (p < 0.05) and several types of bile acid (p < 0.05) levels in gallstone disease model mice. Hitrechol® TID treatment could significantly decrease the frequencies of hepatocyte necrosis and lipid aggregation notably as well as increase the antioxidant enzyme level (p < 0.05) in the liver.

Conclusions
Our findings for the first time demonstrated the beneficial effect of Hitrechol® against gallstone via its litholytic, liver-protective and antioxidant activities.
