ABSTRACT

Immune checkpoint inhibitors (ICI) are monoclonal antibodies that target immune checkpoint inhibitory receptors. They have revolutionised cancer treatment but can be associated with a wide range of adverse side effects. Rarely, they can be associated with the triad of myositis, myasthenia gravis, and myocarditis or overlap syndrome. Prompt recognition and early intervention are needed to treat these potentially life-threatening conditions. We report a case series of patients with ICI-related overlap syndrome, including the first with avelumab, and discuss the current management guidelines.

ABSTRACT

OBJECTIVE: To compare results from 2 previously published surveys aimed at determining how pyometra is treated in high-quality, high-volume spay-neuter clinics (HQHVSNCs) and private practices (PPs), with a specific focus on identifying opportunities for partnership between the clinic types to improve access to care in pyometra treatment. SAMPLE: Responses from 123 PPs and 87 HQHVSNCs. METHODS: A previously published survey of PPs conducted from June to July 2021 and a similar previously published survey of HQHVSNCs conducted from June to July 2020 were compared regarding demographics, pyometra treatment availability, estimated outcome, alternative outcome, disruption, cost, and protocol between HQHVSNCs and PPs. A comparison was also run of the surveys' responses regarding referral of a pyometra to an HQHVSNC by a PP. RESULTS: Although PPs estimated that economic euthanasia is the most likely alternative outcome for 13% of patients unable to access care at their practice, 80% would be reluctant to refer to an HQHVSNC. The 3 primary reasons indicated by PPs with a reluctance to refer were a perceived lack of prompt appointment availability (20%), lack of aftercare (18%), and lack of adequate equipment (14%). In contrast, most HQHVSNCs estimated that they generally accept referrals the same day (50%) or the next day (30%) and 95% of HQHVSNCs reported having the resources needed to treat most pyometras. CLINICAL RELEVANCE: There are several opportunities for partnership between PPs and HQHVSNCs in the treatment of pyometra. The most frequent concerns expressed by PPs regarding referral to HQHVSNCs were not shared by HQHVSNCs or could be ameliorated by referral to an HQHVSNC for surgery and transfer back to the PP for aftercare.

ABSTRACT

BACKGROUND: Epidemiologic evidence suggests an inverse association between sun exposure and follicular lymphoma risk. METHODS: We conducted an Australian population-based family case-control study based on 666 cases and 459 controls (288 related, 171 unrelated). Participants completed a lifetime residence and work calendar and recalled outdoor hours on weekdays, weekends, and holidays in the warmer and cooler months at ages 10, 20, 30, and 40 years, and clothing types worn in the warmer months. We used a group-based trajectory modeling approach to identify outdoor hour trajectories over time and examined associations with follicular lymphoma risk using logistic regression. RESULTS: We observed an inverse association between follicular lymphoma risk and several measures of high lifetime sun exposure, particularly intermittent exposure (weekends, holidays). Associations included reduced risk with increasing time outdoors on holidays in the warmer months [highest category OR = 0.56; 95% confidence interval (CI), 0.42-0.76; Ptrend < 0.01], high outdoor hours on weekends in the warmer months (highest category OR = 0.71; 95% CI, 0.52-0.96), and increasing time outdoors in the warmer and cooler months combined (highest category OR = 0.66; 95% CI, 0.50-0.91; Ptrend 0.01). Risk was reduced for high outdoor hour maintainers in the warmer months across the decade years (OR = 0.71; 95% CI, 0.53-0.96). CONCLUSIONS: High total and intermittent sun exposure, particularly in the warmer months, may be protective against the development of follicular lymphoma. IMPACT: Although sun exposure is not recommended as a cancer control policy, confirming this association may provide insights regarding the future control of this intractable malignancy.

ABSTRACT

BACKGROUND: Everyday memory problems are believed to increase with age, leading many researchers to focus on older ages when examining reports of memory lapses. However, real world memory lapses are ubiquitous across the adult lifespan, though less is known about the types of problems and their impacts at younger ages. The current study examined occurrence and impacts of memory lapses using daily diaries in a broad age range and whether characteristics of lapses varied across age, gender, or education level. METHODS: Using an 8-day daily diary protocol, 2,018 individuals (ages 25-91) provided reports of their experiences of two types of daily memory lapses (retrospective and prospective) as well as the impact those lapses had on their emotional and functional well-being that day. Using multilevel modeling, we examined the likelihood of reporting memory lapses and their impacts on daily life and whether these depended on age, gender, or education level. RESULTS: Participants reported lapses on approximately 40% of days; retrospective memory lapses were significantly more likely than prospective lapses. Older ages and higher education level were related to greater likelihood of reporting retrospective lapses. Women (compared to men) were more likely to report prospective memory lapses. Women also tended to report greater impacts of their memory lapses. Lower education levels were related to greater impacts of memory lapses compared to higher education levels. Interestingly, age was not related to impacts of lapses. DISCUSSION: Our results indicate that memory lapses are common across the lifespan and that those individuals more likely to report lapses are not necessarily those that experience the greatest impacts of those lapses on daily life. Additional work is needed to understand the daily experience of memory lapses and how they differentially affect individuals regardless of age, gender, and education. CONCLUSIONS: Memory lapses are an important aspect of daily life across the lifespan and require measurement in an individual's real-world environments. Better measurement of these experiences will allow the development of more sensitive measures of changes in cognitive functioning that may impact an individual's ability to live independently.

ABSTRACT

OBJECTIVES: We aimed to examine the relationship between occupational exposure to extremely low-frequency magnetic fields (ELF-MFs) and follicular lymphoma (FL) risk. METHODS: We conducted a family case-control study between 2011 and 2016 in Australia and included 681 cases. Controls were either a family member of cases (related (n=294), unrelated (n=179)) or were unrelated recruited for a similarly designed Australian multiple myeloma study (n=711). We obtained detailed job histories using lifetime work calendars. We assigned exposure to ELF-MFs using an enhanced job exposure matrix, with a lag period of 10 years. We examined associations with FL risk using logistic regression accounting for relatedness between cases and controls. We performed sensitivity analyses including by control type, by sex, complete case analyses, ELF-MF exposure percentiles in addition to quartiles, ELF-MF exposure in the maximum exposed job, a shorter lag period (1 year) and the cumulative exposure in the most recent time period (1-9 years). RESULTS: We observed no association with the average intensity, duration or lifetime cumulative exposure to occupational ELF-MF exposure in the primary or sensitivity analyses. CONCLUSIONS: Our findings do not support an association between occupational ELF-MF exposure and FL risk. Although the inclusion of family members as part of the larger control group may have biased our risk estimates towards the null, findings were similar in sensitivity analyses restricted to cases and unrelated controls. Further research incorporating enhanced exposure assessment to ELF-MF is warranted to inform occupational safety regulations and any potential role in lymphomagenesis.

ABSTRACT

Background and Objectives: Subjective cognitive decline (SCD) may be indicative of future objective cognitive decline. However, factors other than objective cognitive performance may influence SCD. This review addresses whether family history or close, nonfamilial exposure to dementia is associated with self-reported SCD. Research Design and Methods: Searches were conducted in PubMed, PsycINFO, Web of Science, and the Dissertations and Theses database. Eligible articles included measures of self-reported cognition for community-dwelling middle-aged or older adults (40+ years) not diagnosed with dementia, and who had either a family history of dementia, a family member, spouse, or close friend with dementia. The quality of evidence was evaluated using the LEGEND Appraisal Tool. Evidence was synthesized narratively. Results: A total of 32 articles were included, with 28 rated as good quality. Across studies, the relationship between dementia exposure and SCD was inconsistent. A significant association between exposure and SCD was found in 6 studies; however, 17 reviewed studies found no evidence of a relationship. The remaining 9 studies found mixed associations. Modifying factors that could potentially influence these associations were exploratorily identified among studies to provide context to our results. These factors included dementia worry, emotional closeness, and measurement sensitivity. Discussion and Implications: Findings of this review suggest that both first-degree relatives and spouses of persons with dementia may have an increased likelihood of reporting SCD, although the current heterogeneity in definitions of exposure to dementia and SCD may influence these findings. In addition to the relationship between dementia exposure and SCD, future research should examine potential modifiers, including meaning attributed to exposure, as identifying how these perceptions affect cognition may promote early intervention.

ABSTRACT

Memory lapses (e.g., forgetting a medication) are common for most people, yet past methods of assessment relied upon retrospective reports from long recall windows. Recently, researchers have incorporated daily diary methods to capture memory lapse frequency closer to the experience in real-world environments. This study describes the utility of the Daily Memory Lapses Checklist using data from two 14-day diary studies (Combined Sample = 467; 66% women). Frequency and impact (i.e., irritation and interference) of prospective and retrospective memory lapses were assessed at both individual- and daily levels. Across studies, memory lapses occurred on more than one-third of assessment days. Retrospective lapses were reported more frequently than prospective; however, both lapses had a similar impact. The Daily Memory Lapses Checklist represents a flexible measure that separates the occurrence of a memory lapse from its impact on daily life: metrics that will enhance our understanding of daily experiences of cognitive functioning.

ABSTRACT

CLINICAL RELEVANCE: Inter-instrument variation in anterior corneal shape (ACS) measurement has a consequence for ocular clinical practice. BACKGROUND: To consider inter-instrument variability in keratometry measurements across the ACS and to explore instrument protocols for determining ACS keratometric analogues (KAs). METHODS: Mean keratometry/KAs of the right eye were recorded using Javal-Schiøtz keratometer (J-S), Orbscan IIz and Pentacam from 124 subjects (78 females; mean ± SD age: 24.71 ± 6.61 years). Mean radii of curvature were obtained for 1-mm wide annular zones extending up to 6 mm (horizontally) and 4 mm (vertically) from the apex for Orbscan and Pentacam. Zonal mean radius of curvature was calculated by averaging keratometry values for all measured points within the zone. RESULTS: KA (mean ± SD): Horizontal: Orbscan (7.80 ± 0.31 mm) and J-S (7.82 ± 0.29 mm) were not significantly different (p = 0.072). Pentacam (7.86 ± 0.29 mm) was significantly flatter than J-S (p < 0.001) and Orbscan (p < 0.001). Vertical: Orbscan (7.64 ± 0.31 mm) was significantly steeper than J-S (7.67 ± 0.29 mm, p < 0.005) and Pentacam (7.70 ± 0.29 mm, p < 0.001). Pentacam was significantly flatter than J-S (p < 0.001) and significant flatter than Orbscan across the entire profile (1-4 mm zones horizontal and vertical, p < 0.001).                        LoAs (CI): J-S/Orbscan: ±0.75 mm (0.05-0.18); J-S/Pentacam: ±0.72 mm (0.01-0.12); Pentacam/Orbscan: ±0.16 mm (0.04-0.08). There was a +0.03 mm positive bias for Orbscan compared to J-S, +0.06 mm positive bias for Orbscan compared to Pentacam and -0.03 mm negative bias for Pentacam compared to J-S. CONCLUSIONS: Algorithms used by Orbscan and Pentacam to solve the peripheral paraxial ray problem produce significantly different KAs. Instrument-specific KAs cannot be used inter-changeably between instruments. Differences in KA between instruments are not significant for ocular surgery, but may influence rigid contact lens fitting. Pentacam measures flatter than Orbscan and J-S.

ABSTRACT

Negative perceptions of aging and older adulthood, including the idealization of youth, are common in the United States. Past work has found that holding negative perceptions of aging is closely associated with poor mental and physical health consequences, yet few studies have examined how these perceptions impact day-to-day experiences. The current study had two objectives: (1) investigate whether age discrepancy (specifically desiring to be younger than one's chronological age) was related to daily negative affect and (2) examine whether this relationship changed as participants aged over time. We utilized the Midlife in the United States (MIDUS) diary study, a longitudinal measurement burst study with three waves of 8-day daily diaries indexing approximately 20 years. Participants (N = 2398; Mage [baseline] = 46.85, SD = 12.24; 54.7% women; 92.4% White) reported their desired age as well as daily negative affect at each wave. Using multilevel modeling, we examined whether age discrepancy predicted daily negative affect across 3 waves of observation. Results supported a significant relationship between age discrepancy and daily negative affect. However, no interactions among age discrepancy and baseline age or time across study were found. This suggests that the relationship between age discrepancy and daily negative affect was consistent across waves and participants over a 20-year period and provides evidence for the pernicious effect of deidentifying with one's real age on daily life. Daily experiences can act as potential risk or protective factors and shape developmental trajectories. Reducing ageism through societal interventions or increasing personal acceptance of aging through targeted interventions are two potential pathways of promoting health and well-being across the lifespan.

ABSTRACT

Guided by intersectional multimodal literacy frameworks and analytic methods, this qualitative study explored how seven high-achieving Black undergraduate women's photo essays visually and textually represented their persistence during the COVID-19 pandemic. Photo essays, in this context, are intersectional multimodal compositions that use images and words to articulate the challenges that the women faced during COVID-19 and the resources that promoted their persistence. Data sources included a demographic questionnaire, the women's digital photo essays, and lengthy photo-elicitation interviews with the women on Zoom. Findings reveal that the women's photo essays evoked an endarkened persistence, rooted in the legacy of Black people's collective struggle and survival, and represented by two interrelated themes: Affirming Black Beauty (i.e., Embracing natural Black hair and Caring for Black female bodies) and Honoring the Spirit (i.e., (Re)connecting with sistafriends, (Re)claiming rest, and Nurturing creativity). Research and practical implications are discussed.

ABSTRACT

BACKGROUND: The influence of early-life growth pattern and body size on follicular lymphoma (FL) risk and survival is unclear. In this study, we aimed to investigate the association between gestational age, growth during childhood, body size, changes in body shape over time, and FL risk and survival. METHODS: We conducted a population-based family case-control study and included 706 cases and 490 controls. We ascertained gestational age, growth during childhood, body size and body shape using questionnaires and followed-up cases (median=83 months) using record linkage with national death records. We used a group-based trajectory modeling approach to identify body shape trajectories from ages 5-70. We examined associations with FL risk using unconditional logistic regression and used Cox regression to assess the association between body mass index (BMI) and all-cause and FL-specific mortality among cases. RESULTS: We found no association between gestational age, childhood height and FL risk. We observed a modest increase in FL risk with being obese 5 years prior to enrolment (OR=1.43, 95 %CI=0.99-2.06; BMI ≥30 kg/m2) and per 5-kg/m2 increase in BMI 5 years prior to enrolment (OR=1.14, 95 %CI=0.99-1.31). The excess risk for obesity 5 years prior to enrolment was higher for ever-smokers (OR=2.00, 95 %CI=1.08-3.69) than never-smokers (OR=1.14, 95 %CI=0.71-1.84). We found no association between FL risk and BMI at enrolment, BMI for heaviest lifetime weight, the highest categories of adult weight or height, trouser size, body shape at different ages or body shape trajectory. We also observed no association between all-cause or FL-specific mortality and excess adiposity at or prior to enrolment. CONCLUSION: We observed a weak association between elevated BMI and FL risk, and no association with all-cause or FL-specific mortality, consistent with previous studies. Future studies incorporating biomarkers are needed to elucidate possible mechanisms underlying the role of body composition in FL etiology.

ABSTRACT

Current management practices of pyometra in the private practice setting are not well documented. The goal of this study was to understand pyometra management in the private practice setting, and the current relationship private practices have with high quality, high volume, spay-neuter (HQHVSN) clinics regarding referral for pyometra surgery. An anonymous electronic survey was piloted and distributed using SurveyMonkey via email, social media, and the Independent Veterinary Practitioners Association targeting veterinarians who see companion animals. A total of 153 responses were received from June to July 2021, with respondents distributed throughout the United States. Practices performed a median of 10 spay and neuters per week, with the median spay cost being $350 (IQR 250-500) for dogs and $250 (IQR 180-350) for cats. The median cost of a pyometra surgery was $1000 (IQR 700-1500) for dogs and $750 (IQR 450-1000) for cats. All practices treated pyometra at least sometimes, despite the disruption (major 19%, moderate 47%, mild 29%, none 5%) to their day. All pyometra presentations were accepted for treatment at least sometimes: BAR/QAR (98%), depressed or non-ambulatory (88%), and obtunded or lateral (62%) with mean estimated survival of 96%, 74%, and 31%, respectively. The majority (56%) of clients were reported to sometimes have trouble paying for all recommended services, while it was less often reported that clients often (31%) or rarely (13%) had trouble. Private practices willing to refer only did so always 20% of the time and sometimes 36% of the time. Private practices will do what they can to treat most pyometras that present at their practice within a timely manner before referring elsewhere. There is currently inconsistent utilization of HQHVSN clinics as a potential referral resource due to location or appointment availability.

ABSTRACT

Memory lapses are a type of daily challenge that are common to most people and are associated with negative mood outcomes. How daily challenges are associated and linked to broad domains, like life satisfaction and well-being, has been underexamined. Life satisfaction is often assessed from a macro-level that emphasizes average differences over longer timeframes, yet daily experiences (i.e., micro-level) may accumulate to shape these characteristics. In the current study, we examined if daily memory lapses (e.g., difficulties with word-finding or forgetting a meeting) were associated with life satisfaction, and whether this relationship was mediated by the associated changes in positive and negative affect due to daily memory lapses. In a coordinated analysis of two datasets (N = 561, ages 25-93 years), we used multilevel structural equation modeling to assess how daily memory lapses may influence the broader outcome of global life satisfaction. The pattern of results was similar across datasets: memory lapses were associated with reduced positive affect and increased negative affect. Further, the daily affect associated with daily memory lapses significantly mediated the relationship between lapses and life satisfaction, while the direct relationship between memory lapses and life satisfaction was non-significant. This study provides support for the role of daily challenges, specifically memory lapses, influencing broader constructs such as psychological well-being by identifying the key factor of affective responses. Future work should identify other salient daily challenges, as well as explore if reducing the affective response to challenges through targeted interventions would mitigate impacts on distal functioning.

ABSTRACT

BACKGROUND: Only a fraction of pediatric trauma patients are treated in pediatric-specific facilities, leaving the remaining to be seen in centers that must decide to admit the patient to a pediatric or adult unit. Thus, there may be inconsistencies in pediatric trauma admission practices among trauma centers. OBJECTIVE: Describe current practices in admission decision making for pediatric patients. METHODS: An email survey was distributed to members of three professional organizations: The American Association for the Surgery of Trauma, Society of Trauma Nurses, and Pediatric Trauma Society. The survey contained questions regarding pediatric age cutoffs, institutional placement decisions, and scenario-based assessments to determine mitigating placement factors. RESULTS: There were 313 survey responses representing freestanding children's hospitals (114, 36.4%); children's hospitals within general hospitals (107, 34.2%), and adult centers (not a children's hospital; 90, 28.8%). The mean age cutoff for pediatric admission was 16.6 years. The most reported cutoff ages were 18 years (77, 25.6%) and 15 years (76, 25.2%). The most common rationales for the age cutoffs were "institutional experience/tradition" (139, 44.4%) and "physician preference" (89, 28.4%). CONCLUSION: There was no single widely accepted age cutoff that distinguished pediatric from adult trauma patients for admission placement. There was significant variability between and within the types of facilities, with noted ambiguity in the definition of a "pediatric" patient. Thresholds appear to be based primarily on subjective criteria such as traditions or preferences rather than scientific data. Institutions should strive for objective, evidence-based policies for determining the appropriate placement of pediatric patients.

ABSTRACT

The association between smoking and alcohol consumption and follicular lymphoma (FL) incidence and clinical outcome is uncertain. We conducted a population-based family case-control study (709 cases: 490 controls) in Australia. We assessed lifetime history of smoking and recent alcohol consumption and followed-up cases (median = 83 months). We examined associations with FL risk using unconditional logistic regression and with all-cause and FL-specific mortality of cases using Cox regression. FL risk was associated with ever smoking (OR = 1.38, 95%CI = 1.08−1.74), former smoking (OR = 1.36, 95%CI = 1.05−1.77), smoking initiation before age 17 (OR = 1.47, 95%CI = 1.06−2.05), the highest categories of cigarettes smoked per day (OR = 1.44, 95%CI = 1.04−2.01), smoking duration (OR = 1.53, 95%CI = 1.07−2.18) and pack-years (OR = 1.56, 95%CI = 1.10−2.22). For never smokers, FL risk increased for those exposed indoors to >2 smokers during childhood (OR = 1.84, 95%CI = 1.11−3.04). For cases, current smoking and the highest categories of smoking duration and lifetime cigarette exposure were associated with elevated all-cause mortality. The hazard ratio for current smoking and FL-specific mortality was 2.97 (95%CI = 0.91−9.72). We found no association between recent alcohol consumption and FL risk, all-cause or FL-specific mortality. Our study showed consistent evidence of an association between smoking and increased FL risk and possibly also FL-specific mortality. Strengthening anti-smoking policies and interventions may reduce the population burden of FL.

ABSTRACT

ERG overexpression has been linked to acute myeloid leukemia/myeloid sarcoma (MS). The aim of our study was to identify the frequency of ERG immunohistochemical (IHC) expression in MS (n = 21), blastic plasmacytoid dendritic cell neoplasms (BPDCNs; n = 8), extramedullary hematopoiesis (EMH: n = 9), normal and pathological bone marrow trephine biopsies (BM-TBs, n = 18), and the marrow component of adrenal myelolipomas (n = 15). ERG-positive and ERG-negative immunostains were identified in 68.4% and 31.5% of patients with MS, respectively (2-3+, 20% to >90% of cells), while all BPDCNs were negative. ERG + MS cases were over-represented in those of myeloid differentiation when compared with those of pure monocytic/monoblastic differentiation, which were ERG-negative (P=<0.001). ERG was expressed in immature myeloid cells in 100% of cases of EMH, BM-TBs, and adrenal myelolipomas (n = 42), resulting in a sensitivity of 100% in this setting. Negative ERG immunostaining was also 100% sensitive in discriminating cells of erythroid lineage, mature lymphocytes, and reactive or neoplastic plasma cells. Variable IHC expression occurred in megakaryocytes and neutrophils. In summary, we confirmed a high frequency of ERG expression in MS and identified ubiquitous expression in non-neoplastic immature myeloid lineage cells. We believe that ERG can be of diagnostic utility to identify neoplastic and reactive myeloid infiltrates in peripheral tissues and possibly as an ancillary marker to exclude the diagnosis of BPDCNs when positive. However, ERG must be used in an antibody panel, as expression is not limited to myeloid cells.

ABSTRACT

BACKGROUND: A previous International Lymphoma Epidemiology (InterLymph) Consortium evaluation of joint associations between five immune gene variants and autoimmune conditions reported interactions between B-cell response-mediated autoimmune conditions and the rs1800629 genotype on risk of B-cell non-Hodgkin lymphoma (NHL) subtypes. Here, we extend that evaluation using NHL subtype-specific polygenic risk scores (PRS) constructed from loci identified in genome-wide association studies of three common B-cell NHL subtypes. METHODS: In a pooled analysis of NHL cases and controls of Caucasian descent from 14 participating InterLymph studies, we evaluated joint associations between B-cell-mediated autoimmune conditions and tertile (T) of PRS for risk of diffuse large B-cell lymphoma (DLBCL; n = 1,914), follicular lymphoma (n = 1,733), and marginal zone lymphoma (MZL; n = 407), using unconditional logistic regression. RESULTS: We demonstrated a positive association of DLBCL PRS with DLBCL risk [T2 vs. T1: OR = 1.24; 95% confidence interval (CI), 1.08-1.43; T3 vs. T1: OR = 1.81; 95% CI, 1.59-2.07; P-trend (Ptrend) < 0.0001]. DLBCL risk also increased with increasing PRS tertile among those with an autoimmune condition, being highest for those with a B-cell-mediated autoimmune condition and a T3 PRS [OR = 6.46 vs. no autoimmune condition and a T1 PRS, Ptrend < 0.0001, P-interaction (Pinteraction) = 0.49]. Follicular lymphoma and MZL risk demonstrated no evidence of joint associations or significant Pinteraction. CONCLUSIONS: Our results suggest that PRS constructed from currently known subtype-specific loci may not necessarily capture biological pathways shared with autoimmune conditions. IMPACT: Targeted genetic (PRS) screening among population subsets with autoimmune conditions may offer opportunities for identifying those at highest risk for (and early detection from) DLBCL.

ABSTRACT

Background: The association between dietary intake of foods of animal origin and follicular lymphoma (FL) risk and survival is uncertain. In this study, we examined the relationship between dietary intake of dairy foods and fats, meat, fish and seafoods, and the likelihood of FL and survival. Methods: We conducted a population-based family case-control study in Australia between 2011 and 2016 and included 710 cases, 303 siblings and 186 spouse/partner controls. We assessed dietary intake of animal products prior to diagnosis (the year before last) using a structured food frequency questionnaire and followed-up cases over a median of 6.9 years using record linkage to national death data. We examined associations with the likelihood of FL using logistic regression and used Cox regression to assess association with all-cause and FL-specific mortality among cases. Results: We observed an increased likelihood of FL with increasing daily quantity of oily fish consumption in the year before last (highest category OR = 1.96, CI = 1.02-3.77; p-trend 0.06) among cases and sibling controls, but no associations with spouse/partner controls. We found no association between the likelihood of FL and the consumption of other types of fish or seafood, meats or dairy foods and fats. In FL cases, we found no association between meat or oily fish intake and all-cause or FL-specific mortality. Conclusion: Our study showed suggestive evidence of a positive association between oily fish intake and the likelihood of FL, but findings varied by control type. Further investigation of the potential role of environmental contaminants in oily fish on FL etiology is warranted.

ABSTRACT

INTRODUCTION: Knowledge about the factors that contribute to the correctional officer's (CO) mental health and well-being, or best practices for improving the mental health and well-being of COs, have been hampered by the dearth of rigorous longitudinal studies. In the current protocol, we share the approach used in the Canadian Correctional Workers' Well-being, Organizations, Roles and Knowledge study (CCWORK), designed to investigate several determinants of health and well-being among COs working in Canada's federal prison system. METHODS AND ANALYSIS: CCWORK is a multiyear longitudinal cohort design (2018-2023, with a 5-year renewal) to study 500 COs working in 43 Canadian federal prisons. We use quantitative and qualitative data collection instruments (ie, surveys, interviews and clinical assessments) to assess participants' mental health, correctional work experiences, correctional training experiences, views and perceptions of prison and prisoners, and career aspirations. Our baseline instruments comprise two surveys, one interview and a clinical assessment, which we administer when participants are still recruits in training. Our follow-up instruments refer to a survey, an interview and a clinical assessment, which are conducted yearly when participants have become COs, that is, in annual 'waves'. ETHICS AND DISSEMINATION: CCWORK has received approval from the Research Ethics Board of the Memorial University of Newfoundland (File No. 20190481). Participation is voluntary, and we will keep all responses confidential. We will disseminate our research findings through presentations, meetings and publications (e.g., journal articles and reports). Among CCWORK's expected scientific contributions, we highlight a detailed view of the operational, organizational and environmental stressors impacting CO mental health and well-being, and recommendations to prison administrators for improving CO well-being.
