Association of salivary testosterone levels during the post-awakening period with age and symptoms suggestive of late-onset hypogonadism in men.

Background: The lack of association between serum testosterone levels and symptoms suggestive of hypogonadism is a significant barrier in the determination of late-onset hypogonadism (LOH) in men. This study explored whether testosterone levels increase after morning awakening, likewise the cortisol awakening response (CAR) in the hypothalamic-pituitary-adrenal (HPA) axis, and whether testosterone levels during the post-awakening period are associated with age and symptoms suggestive of late-onset hypogonadism (LOH) in men.

Methods: Testosterone and cortisol levels were determined in saliva samples collected immediately upon awakening and 30 and 60 min after awakening, and scores of the Aging Males' Symptoms (AMS) questionnaire were obtained from 225 healthy adult men.

Linguistic anomalies observed in the Sentence Completion Test in patients with schizophrenia.

Background: Schizophrenia is a chronic, debilitating disorder characterised by distorted thinking, perceptions, behaviours, and even language impairments. We investigated the linguistic anomalies in Korean schizophrenia patients compared to non-psychotic psychiatric controls to determine whether the linguistic anomalies in English speakers with schizophrenia were replicated in Korean speakers.

Methods: Thirty-four schizophrenia patients and 70 non-psychotic psychiatric controls were included in this study.

Linguistic anomalies in the language of patients with schizophrenia.

In terms of thought disorder, the language of patients with schizophrenia itself could be a valuable resource. Some valuable studies on the language of patients with schizophrenia have been performed. However, most such studies have been confined to English-speaking countries, or at least those where Indo-European languages are spoken.

Association of the HPA axis response to upcoming competition and shooting outcomes in elite junior shooting players.

Successful shooting performance in competition is reliant on several factors such as shooting techniques and competition-associated psychological stresses. This study examined the hypothalamus-pituitary-adrenal (HPA) axis response to upcoming competition and its association with shooting outcomes in elite junior shooting players. The cortisol awakening response (CAR) and dehydroepiandrosterone (DHEA) secretion after awakening were measured for two consecutive days (the day before and on the day of competition for the selection of national shooting team members) in 19 junior men and 21 junior women players, and the shooting scores of the individual players were obtained.

Altered Hypothalamus-Pituitary-Adrenal Axis Function: A Potential Underlying Biological Pathway for Multiple Concurrent Symptoms in Patients With Advanced Lung Cancer.

Objective: Patients with advanced cancer commonly experience multiple symptoms that present as groups or clusters. The present study aimed to examine whether hypothalamus-pituitary-adrenal (HPA) axis dysfunction underlies the concurrent multiple symptoms in patients with advanced cancer.

Methods: Patients' cortisol levels were determined in saliva samples collected after awakening (0, 30, and 60 minutes after awakening) and at nighttime (21:00-22:00 PM) from 46 patients with lung cancer (15.
