Depression is the most common neuropsychiatric complication in HIV-infected patients and may occur in all phases of the infection. Accurately, diagnosing major depressive disorder in the context of HIV is an ongoing challenge to clinicians and researchers, being complicated by the complex biological, psychological, and social factors associated with the HIV illness. Evidences exist to support the importance of improving the identification of depressive symptoms and their adequate treatment. Depression has long been recognized as a predictor of negative clinical outcomes in HIV-infected patients, such as reducing medication adherence, quality of life, and treatment outcome, and possibly worsening the progression of the illness and increasing mortality. By analyzing the most relevant studies (MEDLINE, EMBASE, PsycLit, Cochrane Library), the review discusses the epidemiology and the main clinical features of depression in HIV-infected patients, the causal pathways linking depression and HIV infection, the validity of screening tools, and the efficacy of different treatment approaches, including psychosocial interventions, psychopharmacology as well as HIV-specific health psychology health service models.

With cancer incidence increasing over time, attention to the burden of related psychiatric and psychosocial consequences of the disease and treatment is a major topic for both cancer patients and their caregivers. Among cancer patients, psychiatric (e.g. adjustment, anxiety, depressive disorders) and neuropsychiatric disorders (e.g. cognitive disorders secondary to treatment, delirium) have been shown to affect an average of 30-35% patients, with differences according to stage and type of cancer. Also other psychosocial syndromes (e.g. demoralization, health anxiety, irritable mood) not taken into account in usual nosological systems should be considered for their impact on the patient's quality-of-life. Also, it has been repeatedly reported that psychological distress reverberates substantially throughout the nuclear family, and that a family approach is necessary in cancer care, with the caregiver-patient dyad as a unit to be the focus and direction of assessment and intervention. In this review the most significant psychosocial disorders causing burden for cancer patients and their caregivers are examined, and the main methods of assessment for more proper referral and treatment are summarized.

Routine screening and adequate assessment of depressive spectrum disorders is necessary in patients with cancer in order to effectively manage the multifaceted and complex consequences on cancer care.

This Southern European study confirms the importance of demoralization in cancer patients as a different condition with respect to depression and its relationship with poor QoL and suicidal ideation.

The study presents further evidence that demoralization is a significant clinical condition and that the DS-IT demonstrates satisfactory levels of validity and reliability to support its use in patients in the ambulatory cancer setting.
