Abstract
Little is known about type D personality in patients with obstructive sleep apnea (OSA). The DS-14 questionnaire is the standard tool to assess this personality type, but it has not been properly validated in patients with OSA, nor has it been correlated with clinical features in these patients. PURPOSE To determine the internal consistency and test-retest reliability of the DS-14 questionnaire, as well as the prevalence of type D personality in the overall OSA sample and subgroups. We assessed the influence of type D on perceived symptoms and its congruence with self-reported measures of personality, depression, fatigue, anxiety, quality of life, and quality of sleep. METHODS Patients with OSA completed the DS-14 questionnaire, Big Five Inventory-2 questionnaire, Hospital Anxiety and Depression Scale, SF-36 Health Survey Questionnaire, Epworth Sleepiness Scale and Stanford Sleepiness Scale, Pittsburgh Sleep Quality Index and Insomnia Severity Index, Fatigue Assessment Scale, and Checklist Individual Strength. After 1 month, the DS-14 questionnaire was repeated. RESULTS The overall prevalence of type D personality was 32%. Internal consistency (negative affectivity: α = 0.880, social inhibition: α = 0.851) and diagnostic test-retest reliability (kappa value = 0.664) of the DS-14 questionnaire were high. Significantly more symptoms of anxiety, depression, poor sleep quality, fatigue, and a worse health perception were found in OSA with type D. Neither OSA severity nor REM predominance altered these observations. CONCLUSION The DS-14 questionnaire showed excellent psychometric properties in patients with OSA. The prevalence of type D personality in patients with OSA was higher than in the general population. The presence of type D personality was associated with higher symptom burden.

Abstract
PURPOSE Low anterior resection syndrome (LARS) has had many impacts on the lives of patients and substantial differences in emotional and social functions. The aim of this study was to investigate the correlation analysis of different personality traits in rectal cancer patients with LARS after undergoing curative surgery. METHODS This study was designed as a prospective cohort study. The inclusion criteria included (1) participants diagnosed with rectal cancer who underwent surgical resection of malignant tumors and (2) ECOG 0-1. The primary outcome was the correlation between different personality traits and low anterior resection syndrome in rectal cancer patients after radical surgery. Low anterior resection syndrome incidence rates were estimated by questionnaires and personality groups by the Type A and Type D Scale-14 Personality Inventory. RESULTS For all 161 participants in this study, the presence of a tumor at the lower anal verge and the receipt of neoadjuvant CCRT had a statistically significant positive correlation with the LARS score at 1 month, 6 months, and 1 year (Pearson correlation coefficient = -0.283, -0.374, and - 0.205, respectively), with a p value of less than 0.05. Personalities with Type A, Type D, and Type D-SI scores had a statistically significant positive correlation with LARS score at 1 month (Pearson correlation coefficient = 0.172, 0.162, and 0,164, p value = 0.03, 0.04, and 0.04). CONCLUSION Type A and Type D personalities are highly linked to LARS. Personalized support approaches can ultimately assist rectal cancer patients in overcoming difficulties after surgery and recovery and enhance their functional outcomes.

Abstract
Background Lymphomatoid papulosis (LyP) is a rare condition in pediatrics; LyP histological type D has been reported in only 7 children. The differential diagnosis of LyP in the spectrum of lymphoid proliferation remains controversial. Case presentation A 6-year-old boy presented to Emergency Department with a 3-week history of an erythematous papulo-vesicular itchy eruption over the submandibular regions, trunk and extremities. History, symptoms and laboratory tests were unremarkable. SARS-CoV-2 antigen was negative. The clinical suspicion of pityriasis lichenoides et varioliformis acuta (PLEVA) was posed, and topical steroids were introduced. One week after, he returned with an extensive painful scaly papulo-erythematous rash, with some ulcerated and necrotic lesions, and fever; therefore the child was hospitalized. Biochemical results were within reference limits, except for high level of C-reactive protein, aspartate aminotransferase, alanine transaminase and bilirubin. Due to a persistently high fever, systemic corticosteroid treatment was administered, with a good clinical response and an improvement of the skin lesions. Anti-PVB-19 Immunoglobulin M was detected. Elevated levels of IL-6, IL-10 and IFN-γ were also recorded. Five days post-admission, most of the lesions had cleared, and the child was discharged. Methotrexate was started, with a positive response. At skin biopsy a “PLEVA-like” pattern was apparent, with a dense, wedge shaped lymphoid infiltrate featuring epidermotropism and morphologically comprising pleomorphic and blastic cells. The pattern of infiltration was highlighted by immunohistochemical stains, which prove the process to feature a CD8+/CD30 + phenotype, the latter being intense on larger cells, with antigenic loss. Polymerase chain reaction for T-cell receptor gamma (TCRG) chain clonality assessment documented a monoclonal peak. A diagnosis of LyP type D was favored. Conclusion The reported case encompasses most of the critical features of two separated entities—PLEVA and LyP—thus providing further support to the concept of them representing declinations within a sole spectrum of disease. Studying the role of infectious agents as trigger potential in lymphoproliferative cutaneous disorders and detecting novel markers of disease, such as cytokines, could have a crucial impact on pathogenic disease mechanisms and perspective therapies.

Abstract
Clostridium perfringens is a bacterial species of importance to both public and animal health. Frequently found in food system environments, it presents a risk to food animal health such as dairy herds, and may cross contaminate associated ingredients or food products, with potential to cause sporadic and outbreaks of disease in human populations, including gastroenteric illness. In this study, we characterized C. perfringens isolated from bovine, caprine, and ovine dairy farm systems (n = 8, 11 and 4, respectively). Isolates were phenotypically screened for antimicrobial sensitivity profiling, and subjected to whole genome sequencing to elucidate related genetic markers, as well as examine virulence gene markers, mobile genetic elements, and other features. Both toxin type A and type D isolates were identified (78 % and 22 % of isolates, respectively), including 20 novel sequence types. Resistance to clindamycin was most prevalent among antibiotics screened (30 %), followed by erythromycin (13 %), then penicillin and tetracycline (4 %), although an additional 3 isolates were non-susceptible to tetracycline. Most isolates harboured plasmids, which mobilised virulence markers such as etx, cpb2, and resistance markers tetA(P), tetB(P), and erm(Q), on conjugative plasmids. The presence of type D isolates on caprine farms emphasizes the need for control efforts to prevent infection and potential enterotoxemia. Clostridium perfringens enterotoxin (cpe) was not identified, suggesting lower risk of gastrointestinal illness from contaminated foods, the presence of other virulence and antimicrobial resistance markers suggests farm hygiene remains an important consideration to help ensure food safety of associated dairy foods produced.

Abstract
The role of personality as distal risk factor for suicidal thoughts and behavior is still unclear. This review aims to propose two conceptual models that explain the psychological plausibility of Type D personality as distal risk factor and contributor to the transition from general to suicide distress. To support this aim, we performed a systematic review of existing studies on the association between Type D personality and suicidal distress. A systematic search yielded eight studies that reported on Type D personality and suicidal distress. Type D personality was robustly associated with suicidal thoughts and behaviors, across populations and countries. Type D was related to the level/frequency of suicidal ideation in seven studies, and suicide attempt in two studies. Our first theoretical model identifies intra-psychic (depression, alcohol misuse, posttraumatic stress) and interpersonal (low belonging, social isolation, lack of support) vulnerabilities of individuals with Type D that may fuel the development of suicidal thoughts and behaviors. Type D by itself will not account for why people become suicidal, but our second theoretical model suggests that the avoidant-passive tendencies of Type D individuals may result in persistent problem-solving deficits, and, eventually, feelings of entrapment that may contribute to the desire to escape from pain. We conclude that empirical evidence supports the hypothesized link between Type D personality, and suicidal thoughts and behaviors. Our conceptual models - albeit often supported by indirect evidence - further substantiate the plausibility of this link, and offer concrete guidance for future studies. Primarily, more longitudinal research is necessary.

Abstract
This review provides a broad overview of the relationship of personality with cardiovascular diseases (CVDs). There has been a sustained interest over the last half a century on the issue of relationship between personality traits and CVDs. Type A behavior was the initial focus of inquiry as it was observed that individuals who were competitive, hostile, and excessively driven were overrepresented among patients seeking treatment for CVDs and also were prone to develop coronary artery disease/syndrome. However, the research gradually expanded to assess the relationship of cardiac morbidity with various other personality facets. Furthermore, studies found out that negative effects (including anger and hostility) were also associated with adverse cardiovascular outcomes. Subsequently, a new personality entity named as the type D ‘distressed’ personality, which combined negative affectivity and social inhibition. type D personality then became the area of research and was demonstrated to be related with poorer cardiac outcomes. Interestingly, the results of various research studies are not equivocal, and hence, there are several critiques related to the current understanding of the link between personality construct and the risk of development as well as the outcome of CVDs. Furthermore, few personality traits such as optimism, conscientiousness, openness to experience, and curiosity have been found to be protective factors against development of CVDs and therefore are called ‘cardioprotective’ personality traits. A detailed discussion on the various aspects of personality in relation to CVDs along with a critical appraisal has been presented in this review.

Abstract
OBJECTIVES Type D personality is characterized by the combination of social inhibition and negative affectivity. This study examined the relationship between Type D personality and insomnia symptoms amongst a sample of the general-population. METHODS Adults from the general-population (n = 392) completed online measures of Type D personality (DS14) and insomnia severity. RESULTS Individuals with the Type D personality trait reported significantly greater symptoms of insomnia relative to Non-Type Ds. Moreover, insomnia-symptoms were independently related to negative affectivity (NA) and social inhibition (SI) and the Type D interaction (i.e. synergistic product of SI and NA). Linear regression analysis determined that NA but not SI significantly predicted insomnia symptoms after controlling for age and sex. However, after accounting for the Type D interaction, negative affectivity remained the only significant predictor of insomnia-symptoms. CONCLUSIONS The Type D personality type appears to be related to insomnia-symptoms, both as a categorical and dimensional construct. These outcomes support prior research evidencing that whilst Type D personality is related to poor sleep in adolescents, NA appears to be the main contributor.

Abstract
The aim of this study is to explore whether different coping strategies are able to mediate the association between Type D personality and quality of life. We collected information from 156 consecutive patients (response rate: 72.9%; 75.0% women; median age: 40 ± 3 years). Patients completed the Type D Scale-14, the Coping Self-Efficacy Scale and the Short-Form Health Survey for measuring physical and mental quality of life. The mediating effect of coping was analysed using correlations, linear regressions and the Sobel z-test. In the mental quality of life, all three studied coping strategies mediated the association between Type D personality and quality of life.

Abstract
OBJECTIVE Distressed (Type D) personality, combining high negative affectivity and social inhibition, is linked to poor health in various populations. Because patients with fibromyalgia experience high negative affect and show signs of social inhibition, this study aimed to examine the prevalence of Type D's components and their associations with health in an additive (worse health with both components present) or synergistic way (components amplifying each other's effects). METHOD Type D personality and physical and mental health were assessed online by 558 patients with self-reported fibromyalgia (94% women, age 47 ± 11 (21-77)years) by the Type D Scale-14 and RAND-36 Health Status Inventory. RESULTS Using the standard cutscores, Type D personality was present in 56.5% of patients. Negative affectivity alone and combined with social inhibition was associated with worse mental and, more limited, physical health, but no interactive (synergistic) associations were found. CONCLUSIONS Type D personality in fibromyalgia exceeds prevalence estimates in general, cardiovascular and chronic pain populations. Some indication of an additive but not of a synergistic effect was found, particularly for mental health, with clearly the largest associations for negative affectivity. The high prevalence of Type D's components may have specific treatment implications.

Abstract
Influenza D virus (FLUDV) was isolated from diseased pigs with respiratory disease symptoms in 2011, and since then the new virus has also been spread to cattle. Little is known about the susceptibility of other agricultural animals and poultry to FLUDV. This study was designed to determine if other farm animals such as goats, sheep, chickens, and turkey are possible hosts to this newly emerging influenza virus. 648 goat and sheep serum samples and 250 chicken and turkey serum samples were collected from 141 small ruminant and 25 poultry farms from different geographical locations in the United States and Canada. Serum samples were examined using the hemagglutination inhibition (HI) assay and the sheep and goat samples were further analyzed using the serum neutralization assay. Results of this study showed FLUDV antibodies were detected in 13.5% (17/126) of the sampled sheep farms, and 5.2% (29/557) of tested sheep serum samples were positive for FLUDV antibodies. For the goat results, the FLUDV antibodies were detected in 13.3% (2/15) of the sampled farms, and 8.8% (8/91) of the tested goat serum samples were positive for FLUDV antibodies. Furthermore, all tested poultry serum samples were negative for FLUDV antibodies. Our data demonstrated that sheep and goat are susceptible to FLUDV virus and multiple states in U.S. have this virus infection already in these two species. This new finding highlights a need for future surveillance of FLUDV virus in small ruminants toward better understanding both the origin and natural reservoir of this new virus.
