Teaming-up nurses with ophthalmologists to expand the reach of eye care in a middle-income country: Validation of health data acquisition by nursing staff in a telemedicine strategy.

Telemedicine can be used to conduct ophthalmological assessment of patients, facilitating patient access to specialist care. Since the teleophthalmology models require data collection support from other health professionals, the purpose of our study was to assess agreement between the nursing technician and the ophthalmologist in acquisition of health parameters that can be used for remote analysis as part of a telemedicine strategy. A cross-sectional study was conducted with 140 patients referred to an ophthalmological telediagnosis center by primary healthcare doctors. The health parameters evaluated were visual acuity (VA), objective ophthalmic measures acquired by autorefraction, keratometry, and intraocular pressure (IOP). Bland-Altman plots were used to analyze agreement between the nursing technician and the ophthalmologist. The Bland-Altman analysis showed a mean bias equal to zero for the VA measurements [95%-LoA: -0.25-0.25], 0.01 [95%-LoA: -0.86-0.88] for spherical equivalent (M), -0.08 [95%-LoA: -1.1-0.95] for keratometry (K) and -0.23 [95%-LoA: -4.4-4.00] for IOP. The measures had a high linear correlation (R [95%CI]: 0.87 [0.82-0.91]; 0.97 [0.96-0.98]; 0.96 [0.95-0.97] and 0.88 [0.84-0.91] respectively). The results observed demonstrate that remote ophthalmological data collection by adequately trained health professionals is viable. This confirms the utility and safety of these solutions for scenarios in which access to ophthalmologists is limited.

The use of telemedicine to support Brazilian primary care physicians in managing eye conditions: The TeleOftalmo Project.

PURPOSE: To determine whether teleophthalmology can help physicians in assessing and managing eye conditions and to ascertain which clinical conditions can be addressed by teleophthalmology in primary care setting. METHODS: We evaluated the resolution capacity of TeleOftalmo, strategy implemented in the public health system of southern Brazil. Resolution capacity was defined as the ability to fully address patients' eye complaints in primary care with remote assistance from ophthalmologists. Data from tele-eye reports were collected over 14 months. Resolution capacity was compared across different age groups and different ocular conditions. RESULTS: Overall, 8,142 patients had a tele-eye report issued in the study period. Resolution capacity was achieved in 5,748 (70.6%) patients. When stratified into age groups, the lowest capacity was 43.1% among subjects aged ≥65 years, while the highest was 89.7% among subjects aged 13-17 years (p<0.001). Refractive error (70.3%) and presbyopia (56.3%) were the most prevalent conditions followed by cataract (12.4%) and suspected glaucoma (7.6%). Resolution capacity was higher in cases of refractive error, presbyopia, spasm of accommodation and lid disorders than in patients diagnosed with other condition (p<0.001). CONCLUSIONS: With telemedicine support, primary care physicians solved over two-thirds of patients' eye or vision complaints. Refractive errors had high case resolution rates, thus having a great impact on reducing the number of referrals to specialty care. Teleophthalmology adoption in primary-care settings as part of the workup of patients with eye or vision complaints promotes a more effective use of specialty centers and will hopefully reduce waiting times for specialty referral.

Prevalência de Candida spp. em biofilme dentário de usuários de aparelhos ortodônticos fixos / Prevalence of Candida spp. in the dental biofilm of fixed orthodontic appliances users

OBJETIVOS: O presente estudo tem como objetivo avaliar a prevalência de Candida spp. em biofilme dentário de usuários de aparelhos ortodônticos fixos (AOF) e relacionar com seus hábitos e características.MATERIAIS E MÉTODOS: Foram isolados e identificados cepas de Candida em amostras de saliva em indivíduos usuários de AOF com presença de biofilme microbiano e indivíduos usuários de AOF mas sem presença de biofilme (grupo controle), a partir do cultivo em laboratório.RESULTADOS: Neste estudo foram analisadas 108 amostras de indivíduos com biofilme, e 51 indivíduos no grupo controle. Das 108 amostras analisadas, 52 (48,1%) foram negativas para o gênero Candida e 56 (55,2%) foram positivas, sendo que em oito pacientes foram isolados duas espécies de Candida, quatro pacientes com C. albicans e C. krusei, um com C. albicans e C. tropicalis, um com C. albicans e C. glabrata, um com C. tropicalis e C. glabrata e um com C. tropicalis e C. krusei. No grupo controle 33,3% apresentaram isolamento de Candida, mesmo não apresentando biofilme.CONCLUSÃO: Foram detectadas espécies de Candida patogênicas e intrinsicamente resistentes aos convencionais antifúngicos, ressaltando a importância do diagnóstico micológico para um tratamento adequado das infecções causadas por este grupo de fungos presentes na cavidade oral dos indivíduos.

OBJECTIVES: This study aims to evaluate the prevalence of Candida spp. in dental plaque of users of fixed orthodontic appliances (FOA) and relate to their habits and characteristics.MATERIALS AND METHODS: We isolated and identified strains of Candida in saliva samples from individuals using FOA with the presence of microbial biofilm and individuals without the presence of biofilm (control group) in the laboratory cultivation.RESULTS: We analyzed 108 samples from individuals with biofilm and 51 individuals in the control group. Of the 108 samples analyzed, 52 (48.1%) were negative for Candida and 56 (55.2%) were positive, with eight patients were isolated two species of Candida, four patients with C. albicans and C. krusei, with one C. albicans and C. tropicalis, with one C. albicans and C. glabrata, with one C. tropicalis and C. glabrata and with one C. tropicalis and C. krusei. In the control group 33.3% had isolated Candida, even showing no biofilm.CONCLUSION: Were detected and pathogenic Candida species intrinsically resistant to conventional antifungal agents, emphasizing the importance of mycological diagnosis for appropriate treatment of infections caused by this group of fungi present in the oral cavity of individuals.
