It is generally understood that pain experience and opioid abuse have relied on male-dominated models. However, sex and gender play a role in both pain experience and opioid use disorder. Using the previously validated Texas Tech University Health Sciences Center Sex and Gender Specific Health PubMed Advanced Search Tool, the authors used pertinent literature to develop this literature-based commentary on sex and gender differences in pain experience and opioid use disorder. Women report their experience of pain more frequently, have increased rates of diagnoses related to pain, have increased pain sensitivity, and have a variable response to pain and analgesia...

Objective Sub-health status has progressively gained more attention from both medical professionals and the publics. Treating the number of sub-health symptoms as count data rather than dichotomous data helps to completely and accurately analyze findings in sub-healthy population. This study aims to compare the goodness of fit for count outcome models to identify the optimum model for sub-health study. Methods The sample of the study derived from a large-scale population survey on physiological and psychological constants from 2007 to 2011 in 4 provinces and 2 autonomous regions in China...

Sexual assault, partner abuse, and stalking are major problems on college campuses. Past research has demonstrated a host of physiological and psychological outcomes associated with victimization; however, there has been little research conducted on the potential academic outcomes associated with victimization. The purpose of this study was to measure the relation between academic outcomes and experiences of sexual violence, intimate partner violence, and stalking victimization among college students. A sample of 6,482 undergraduate students currently enrolled at one of eight universities in New England was surveyed using items from the subscales of the College Persistence Questionnaire (Academic Efficacy, Collegiate Stress, Institutional Commitment, and Scholastic Conscientiousness)...

The hypothalamic-pituitary-adrenal (HPA) axis represents an important and evolutionarily ancient biological pathway linking physical and psychological stressors with human health. Despite considerable research exploring the physiological stress response among developed populations, few studies have examined HPA activity in non-industrialized contexts, restricting understanding of variation in human stress reactivity across global socio-ecological diversity. The present study addresses this shortcoming by investigating diurnal cortisol rhythms among Garisakang forager-horticulturalists of remote, lowland Papua New Guinea...

Patients who survive influenza A (H7N9) virus infection are at risk of physical and psychological complications of lung injury and multi-organ dysfunction. However, there were no prospectively individualized assessments of physiological, functional and quality-of-life measures after hospital discharge. The current study aims to assess the main determinants of functional disability of these patients during the follow-up. Fifty-six influenza A (H7N9) survivors were investigated during the 2-year after discharge from the hospital...

OBJECTIVE Depression and anxiety have been demonstrated to have negative impacts on outcomes after spine surgery. In patients with cervical deformity (CD), the psychological and physiological burdens of the disease may overlap without clear boundaries. While surgery has a proven record of bringing about significant pain relief and decreased disability, the impact of depression and anxiety on recovery from cervical deformity corrective surgery has not been previously reported on in the literature. The purpose of the present study was to determine the effect of depression and anxiety on patients' recovery from and improvement after CD surgery...

In the world of pain, we must always consider the presence of gender. In nociception, as well as in pain, women are different from men in many, if not all, aspects of the system. Nociception is the sum of several events that occur from the periphery to the CNS, and there is much evidence that female nociception differs from male nociception. Moreover, it has to be considered that pain results from a male or a female cortex. Genetic, anatomical, physiological, hormonal, psychological, and social factors have been considered to explain the differences present at both levels...

It has not yet been established if resting state (RS) connectivity reflects stable characteristics of the brain, or if it is modulated by the psychological and/or physiological state of the participant. Based on research demonstrating sex hormonal effects in task-related brain activity, the present study aimed to investigate corresponding differences in RS networks. RS functional Magnetic Resonance Imaging (RS fMRI) was conducted in women during three different menstrual cycle phases, while men underwent three repeated RS fMRI testing sessions...

The association between racial discrimination (discrimination) and stress-related alterations in the neuroendocrine response-namely, cortisol secretion-is well documented in African Americans (AAs). Dysregulation in production of cortisol has been implicated as a contributor to racial health disparities. Guided by Clark et al. (Am Psychol 54(10):805-816, 1999. doi: 10.1037/0003-066X.54.10.805 ) biopsychosocial model of racism and health, the present study examined the psychological pathways that link discrimination to total cortisol concentrations in AA males and females...

Patients with gender dysphoria are offered cross-sex hormone therapy and sex reassignment surgery to achieve the transition between the sex assigned at birth and gender identity. According to international guidelines, cross-sex hormone therapy in trans-women should lead to a psychologically and physiologically healthy body with feminized serum hormone levels, resulting in suppression of spermatogenesis. However, in a recently published multi-center study, we discovered a high proportion of patients with male serum hormone levels and qualitatively intact spermatogenesis on the day of sex reassignment surgery...

BACKGROUND: Stress is a prevailing risk factor for mood-related illnesses, wherein women represent the majority of those affected by major depression. Despite the growing literature suggesting that affective disorders can arise after a traumatic event is vicariously experienced, this relationship remains understudied in female subjects at the preclinical level. Thus, the objective of the current investigation was to examine whether exposure to emotional and/or psychological stress (ES) mediates depression-related outcomes in female mice...

BACKGROUND: It has been proposed that increased physiological responses (i.e., cardiovascular reactivity) to a stressor or stressors may increase the risk of developing cardiovascular disease (CVD) including increased blood pressure (BP) or hypertension. However, many prospective studies have examined the hemodynamic reactions to laboratory stress tests and CVD in Western countries and only a few studies have examined with varying durations of follow-up in the same sample studies. In addition, still relatively little is known about cardiovascular reactivity in Asian populations...

BACKGROUND: Recent research findings suggest that women who report high anxiety sensitivity (AS; the fear of physiologic sensations associated with anxiety) also report increased sexual dysfunction and decreased sexual satisfaction. Moreover, findings suggest that maladaptive emotion regulation (ER) can contribute to the relation between AS and psychological distress, thereby indirectly influencing sexual outcomes. Identifying relations among these variables and how they specifically relate to sexual outcomes could be vital for diagnostic and therapeutic purposes...

Mahboubeh Ghanbari, Asghar Ghasemi
Maternal hypothyroidism (MH) is the most common cause of transient congenital hypothyroidism. Different animal models are used for assessing developmental effects of MH in offspring. The severity and status of hypothyroidism in animal models must be a reflection of the actual conditions in humans. To obtain comparable results with different clinical conditions, which lead to MH in humans, several factors have been suggested for researchers to consider before designing the experimental models. Regarding development of fetal body systems during pregnancy, interference at different times provides different results and the appropriate time for induction of hypothyroidism should be selected based on accurate time of development of the system under assessment...

REVIEW

Sex and intimacy presents special challenges for the ostomate. Since some colorectal surgery patients will require either temporary or permanent stomas, intimacy and sexuality is a common issue for ostomates. In addition to the stoma, nerve damage, radiotherapy, and chemotherapy are often used in conjunction with stoma creation for cancer patients, thereby adding physiological dysfunction to the personal psychological impact of the stoma, leading to sexual dysfunction. The purpose of this paper is to describe the prevalence, etiology, and the most common types of sexual dysfunction in men and women after colorectal surgery and particularly those patients with stomas...

Hormones have a key role in energy allocation, so their study allows understanding individual metabolic strategies. Because different hormones convey different information on the responses of individuals to energetic demands, a simultaneous analysis of variation in multiple hormones may offer a more reliable picture of metabolic strategies than single hormone assessments. In this study we focused on determining which factors were related to variation in fecal glucocorticoid and thyroid hormone metabolites in wild mantled howler monkeys (Alouatta palliata)...
