Evaluation of the Effectiveness of Digital Technology Interventions to Reduce Loneliness in Older Adults: Systematic Review and Meta-analysis.

Background: Loneliness is a serious public health issue, and its burden is increasing in many countries. Loneliness affects social, physical, and mental health, and it is associated with multimorbidity and premature mortality. In addition to social interventions, a range of digital technology interventions (DTIs) are being used to tackle loneliness.

The COVID-19 Pandemic: A Pandemic of Lockdown Loneliness and the Role of Digital Technology.

The focus of this perspective is on lockdown loneliness, which we define as loneliness resulting from social disconnection as a result of enforced social distancing and lockdowns during the COVID-19 pandemic. We also explore the role of digital technology in tackling lockdown loneliness amid the pandemic. In this regard, we highlight and discuss a number of the key relevant issues: a description of lockdown loneliness, the burden of lockdown loneliness during the COVID-19 pandemic, characteristics of people who are more likely to be affected by lockdown loneliness, factors that could increase the risk of loneliness, lockdown loneliness as an important public health issue, tackling loneliness during the pandemic, digital technology tools for social connection and networking during the pandemic, assessment of digital technology tools from the end users' perspectives, and access to and use of digital technology for tackling lockdown loneliness during the COVID-19 pandemic.

Hematoidin crystals in sputum smears: Cytopathology and clinical associations.

Background: There has been limited correlation of hematoidin crystals (HC) in sputum with clinical and diagnostic characteristics, partly because they are difficult to recognize. The aim of this study was, therefore, to assess these relationships in a consecutive cohort of sputum samples from patients submitted to a cytology laboratory.

Methods: Adequate sputum samples from 489 individuals were enrolled in this study.

Protozoan Cysts in Faecal Pellets of German Cockroaches (Blattella germanica), with Particular Emphasis on Lophomonas blattarum.

Purpose: The aim of this study was to investigate protozoan cysts and oocyts in the faecal pellets of the German cockroach (Blattella germanica), with emphasis on the prevalence of Lophomonas blattarum.

Methods: Thirty adult Blattella germanica (12 males; 18 females) were trapped near Madrid, Spain. Expelled faecal pellets were collected in the laboratory over 5 days in two plastic containers.

Ciliated nasal epithelial cells damage and human rhinovirus infection: cytological findings.

Human rhinovirus infection has been identified as the commonest cause of common cold. We were therefore interested in cytological assessment of nasal cells from patients with human rhinovirus infection. Cytological examination was undertaken of nasal smears from a group of 7 patients, 4 females and 3 males; aged between 27 and 14 years-old (average = 17.

The prevalence of protozoa in the gut of German cockroaches (Blattella germanica) with special reference to Lophomonas blattarum.

The German cockroach (Blattella germanica) is a common domestic pest, which produces allergens that have been associated with broncho-pulmonary disease. Various protozoan species have been identified in the intestine of this cockroach and it has been hypothesised that these protozoa, or their proteases, may contribute to the burden of cockroach-associated allergens and adjuvants present in domestic dust. The aim of this study was therefore to determine the prevalence of protozoan species in the intestine of Blattella germanica.

Bronchopulmonary lophomoniasis: emerging disease or unsubstantiated legend?

The relationship between Lophomonas, a genus of multiflagellated protozoa, and respiratory pathology has recently received attention. Here, we summarize the origin, mode of transmission, pathogenic mechanism and relevant clinical data of bronchopulmonary lophomoniasis.

Lophomonas blattarum and bronchopulmonary disease.

The natural habitat of the multiflagellate protozoon Lophomonas blattarum is as an endocommensal in the hindgut of insects such as cockroaches. However, it also causes bronchopulmonary disease in humans. The aim of this paper was to review the literature on this organism in the context of respiratory disease.

Differences in fungi present in induced sputum samples from asthma patients and non-atopic controls: a community based case control study.

Background: There is emerging evidence for the presence of an extensive microbiota in human lungs. It is not known whether variations in the prevalence of species of microbiota in the lungs may have aetiological significance in respiratory conditions such as asthma. The aim of the study was to undertake semi-quantitative analysis of the differences in fungal species in pooled sputum samples from asthma patients and controls.

Clinical and immunological characteristics associated with the presence of protozoa in sputum smears.

The objective of this study is to assess the relationship between protozoa in spontaneously expectorated sputum samples and a range of clinical and immunological variables. Clinical details including age, gender, smoking status, and use of oral or inhaled steroids were recorded for a cohort of 199 patients whose spontaneously expectorated sputum samples were submitted to a Cytology Laboratory in Spain between January 2005 and December 2006. Slides were scanned for protozoa under light microscopy and scanned for monocytes/small macrophages highlighted by immunocytochemistry (CD68 monoclonal antibody).

Experimental method for isolating and identifying dust mites from sputum in pulmonary acariasis.

The aim of this study was to pilot a simpler and more effective method for identifying dust mites in sputum. Dust mites and their allergens have been implicated in respiratory diseases, including pulmonary acariasis, and several studies have identified mites in sputum. Further research is dependent on the development of a faster and simpler diagnostic test.
