The impact of frailty and illness perceptions on quality of life among people living with HIV in Greece: A network analysis.

OBJECTIVE: Despite the significant advances in healthcare, people living with HIV still face challenges that affect their quality of life (QoL), both in terms of their physical state as represented by frailty and of their illness perceptions (IP). The aim of this study was to unravel the associations between these constructs (QoL, frailty, IP). METHODS: This multicenter, cross-sectional study included 477 people living with HIV (93% male; median age = 43 years, IQR = 51.7) from six HIV clinics in Greece. Frailty phenotype, QoL and IP were assessed using Fried's criteria, EuroQoL (EQ-5D-5L) and Brief Illness Perception Questionnaire (BIPQ), respectively. Network analysis model was utilized. RESULTS: Among frailty criteria, exhaustion had the highest expected influence, while the strongest correlation concerns exhaustion and weak grip strength (pr = 0.14). Regarding the QoL items, usual activities displayed the highest expected influence. The correlations of pain/discomfort with mobility (pr = 0.31), and usual activities with self-care (pr = 0.34) were the strongest. For the BIPQ items, the strongest correlation was found between illness concern and emotional response (pr = 0.45), whereas the latter item was the one that displayed the highest expected influence. Three communities were formed: 1) personal control, treatment control and coherence, 2) the frailty items with mobility, self-care, usual activities, and pain/discomfort, and 3) the rest BIPQ items with anxiety/depression. Identity displayed the highest bridge strength, followed by pain/discomfort, usual activities and consequences. CONCLUSIONS: The interplay between QoL, frailty, and IP in people living with HIV requires clinical attention. Self-reported exhaustion, slow walking speed, and low physical activity affect the physical QoL dimensions, while anxiety/depression is strongly associated with illness-related concern and perceived emotional effects, leading to psychological distress. Symptom management can improve QoL, and information on the disease and treatment can enhance control over the disease. Developing interventions to address QoL, frailty, and IP is crucial.

Mapping frailty in people living with HIV: A nationwide study in Greece.

OBJECTIVES: Frailty is known to affect people living with HIV prematurely, compared to the ageing seronegative population. In this cross-sectional study, we aimed to assess frailty prevalence in people living with HIV in Greece and find associations of frailty criteria with clinical data. METHODS: Demographic and clinical data were collected from 477 participants in six HIV clinics. Fried's frailty phenotype was used to assess frailty prevalence, and participants were classified as frail, pre-frail or robust. Associations of several factors with overall frailty phenotype, as well as with frailty criteria, were explored. RESULTS: The median age was 43 years old (IQR = 51.5) and 444/477 (93%) were men. Most of the participants (429/477, 93.5%) had an undetectable HIV viral load, and a CD4 cell count over 500 cells/µl (366/477, 76.7%). Frailty assessment classified 285/477 (62.1%) as robust, 155/477 (33.8%) as pre-frail and 19/477 (4.1%) as frail. Weakness in grip strength was the most prevalent criterion (128/477, 26.8%), followed by exhaustion (46/477, 9.6%). Lower CD4 cell count, history of AIDS diagnosis, CNS disorders, psychiatric diagnoses, and polypharmacy were strongly associated with frailty. CONCLUSIONS: Although the prevalence of frailty in people living with HIV in Greece is uncommon, when combined with pre-frailty over a third of people are affected, which requires attention in clinical practice. The physical and psychological aspects of frailty highlight the need for a holistic approach to prevent or counteract it. The diverse associations of frailty criteria with HIV-related and non-HIV-related factors suggest a possible variation in people's different healthcare needs.

An exploration of the quality of life of people living with HIV in Greece: Challenges and opportunities.

OBJECTIVE: Improving the quality of life (QoL) of people living with HIV (PLWH) has been proposed as a new priority in HIV care. The objective of this cross-sectional, qualitative study was to explore the perspectives of PLWH in Greece regarding their QoL. DESIGN: Twenty-four semi-structured interviews were conducted with PLWH receiving care across six HIV clinics in Greece. The thematic analysis of the transcribed interviews resulted in four themes and eleven subthemes. RESULTS: First, fear of repercussions (e.g., stigmatization) makes PLWH reluctant to disclose their diagnosis in public settings or disclose accounting for factors like the confidant's discretion. Second, participants are challenged by HIV's unique biopsychosocial facets (e.g., uncertainty about symptoms) and fear for the future (e.g., a confidant revealing their HIV status without consent). Third, support received by specialist services is satisfactory in contrast to non-HIV specialist services, where significant improvements are needed to reduce stigmatization. Finally, the experiences of PLWH include contrasting elements of post-traumatic growth and an inability to accept their seropositivity (e.g., avoiding social interactions). CONCLUSIONS: Empowering PLWH in these QoL areas is greatly needed. Increasing the life expectancy of PLWH is only the initial step; their QoL needs to be secured as the next priority in HIV care.

Pineal region tumors: pathophysiological mechanisms of presenting symptoms.

Pineal region tumors (PRTs) affect all ages, with a remarkable proportion of cases occurring in children. They are mainly classified into three categories, namely germ cell tumors (GCTs), pineal parenchymal tumors (PPTs), and other tumors such as gliomas and tumors of the surrounding structures. The purpose of this article is to review the current literature regarding pathophysiological mechanisms of the presenting clinical features of patients with PRT. The usual presentation of PRTs is the symptoms of obstructive hydrocephalus and intracranial hypertension, such as headache and vomiting. However, there is a remarkable spectrum of clinical findings that can be caused by such lesions. These include ophthalmologic and endocrinologic disturbances, motor and sensory abnormalities, and cognitive and psychiatric symptoms. The unique anatomic location of the pineal gland, which is close to many vital brain structures, is crucial for the explanation of most of those findings. In rare cases, manifestations of intracranial bleeding may be the presenting feature of a PRT. Tumor histology and patient's age can affect the clinical presentation. Hydrocephalus is the most common clinical syndrome of a PRT because of the location of the pineal gland. Presenting symptoms also include ophthalmologic, endocrinologic, motor, sensory, cognitive, and psychiatric symptoms. Clinicians should be aware of the initial symptoms of PRTs, including the misleading ones, in order to avoid delay in the diagnosis and management of these life-threatening lesions.

Toxocariasis of the Nervous System.

PURPOSE: Toxocariasis is a helminthozoonosis caused by the infection of a human host by the larva of Toxocara spp., predominately involving Toxocara canis and Toxocara cati, which are common nematodes in dogs and cats, respectively. Human transmission occurs through contact with animals or by consumption of food contaminated with parasite's eggs. The purpose of this article is to review the current knowledge regarding human neurotoxocariasis. METHODS: We conducted a systematic review of the existing literature concerning toxocariasis of the nervous system. RESULTS: Clinical spectrum of human toxocariasis varies widely from a subclinical course to significant organ morbidity. Clinical course depends on parasitic load, the migration route of the larvae and host response. Human neurotoxocariasis is a relatively rare entity yet associated with severe sequelae. Manifestations include meningitis (usually eosinophilic), encephalitis, myelitis, cerebellar vasculitis, space-occupying lesion, behavioral abnormalities, and optic neuritis. Even though valid diagnostic criteria are lacking, neurotoxocariasis should be suspected in patients with neurologic symptoms and cerebrospinal fluid (CSF) pleocytosis with eosinophilia, positive serology for anti-Toxocara antibodies, in serum and/or CSF, sterile CSF and clinical improvement after antihelminthic treatment. Neurotoxocariasis is treated by benzimidazole components, most frequently albendazole, corticosteroids, or diethylcarbamazine. CONCLUSION: Parasite larvae migrate through tissues and are able to reach the nervous system causing neurotoxocariasis. Its clinical spectrum varies and includes myelitis, meningoencephalitis, brain abscess, and vasculitis. Neurotoxocariasis should always be suspected in patients with neurologic symptoms accompanied by eosinophilia in blood and/or CSF. Early diagnosis and treatment could prevent long-term neurologic impairment.

Presenting Symptoms of Pituitary Apoplexy.

The classical term "pituitary apoplexy" (PA) describes a clinical syndrome usually characterized by abrupt onset of headache accompanied by neurologic and/or endocrinologic deterioration due to sudden expansion of a mass within the sella turcica as a result of hemorrhage or infarction within a pituitary tumor and adjacent pituitary gland. PA is a medical emergency and a difficult diagnosis to establish. Thus this article reviews the presenting symptoms of PA patients to help clinicians recognize or at least suspect this critical condition early on. PA commonly occurs in the setting of a preexisting adenoma, and several patients are unaware of its existence prior to the onset of apoplexy symptoms, which are mainly of a neurologic, ophthalmologic, and endocrinologic nature. Neurologic symptoms include sudden-onset severe headache and other symptoms of subarachnoid hemorrhage, symptoms from compression of the cavernous sinus contents, nausea/vomiting, impaired consciousness, and symptoms of meningeal irritation. Ophthalmologic symptoms include visual field defects, visual loss, diplopia, and ophthalmoplegia. Endocrinologic disturbances include pituitary adenoma symptoms, cortisol deficiency, panhypopituitarism, diabetes insipidus, and syndrome of inappropriate secretion of antidiuretic hormone. Magnetic resonance imaging is the imaging method of choice to aid the PA diagnosis. Its differential diagnoses include cerebrovascular accidents, infectious diseases, and other causes of endocrinologic imbalance. Transsphenoidal surgery is the treatment of choice, especially if there are associated visual abnormalities and ophthalmoplegia. Clinicians should be aware of the presenting symptoms because early diagnosis may reduce the morbidity and mortality of this neurosurgical emergency.
