RESUMO

BACKGROUND: Laser skin resurfacing is a popular cosmetic procedure for noninvasive skin rejuvenation. Since health insurance plans often do not cover these types of procedures, patients often pay out of pocket. Consequently, there is an incentive to go abroad, where prices are more affordable. However, practitioners in destination countries may lack rigorous training on laser safety, regulatory oversight, or licensing, especially on devices used for "cosmetic" procedures. In certain cases, this can lead to tragic outcomes, especially when underqualified practitioners operate medical-grade laser devices. CASE PRESENTATION: A 29-year-old woman suffered a retinal burn from a handheld Q-switched neodymium-doped yttrium aluminum garnet (Nd:YAG) laser pulse device used to perform skin resurfacing treatment at a medical spa in Vietnam. The patient was not adequately informed about the potential risk to her vision and was not provided with any eye protection. A momentary, unintended laser exposure to the patient's right eye led to irreversible vision loss due to a macular burn. This incident caused immediate pain, followed by the sudden appearance of floaters, along with a retinal and vitreous hemorrhage. Despite treatment with off-label bevacizumab for the development of a choroidal neovascular membrane, vision remained at the level of counting fingers because of the presence of the macular scar. CONCLUSION: When utilizing laser-based devices, it is crucial to employ safety measures, such as the wearing of safety goggles or the use of eye shields to protect ocular tissues from potential damage. The growing availability of cosmetic laser devices presents a substantial public health risk, because numerous operators lack adequate training in essential safety standards, or they neglect to follow them. Furthermore, patients seeking services abroad are subject to the regulatory practices of the destination country, which may not always enforce the requisite safety standards. Further research is needed to determine regional and global incidence of laser-related injuries to help direct educational and regulatory efforts.

RESUMO

INTRODUCTION: Patients with advanced age-related macular degeneration (AMD) frequently experience loss to follow-up (LTFU), heightening the risk of vision loss from treatment delays. This study aimed to identify factors contributing to LTFU in patients with advanced AMD and assess the effectiveness of telephone-based outreach in reconnecting them with eye care. METHODS: A custom reporting tool identified patients with advanced AMD who had not returned for eye care between 31 October 2021 and 1 November 2022. Potentially LTFU patients were enrolled in a telephone outreach programme conducted by a telehealth extender to encourage their return for care. Linear regression analysis identified factors associated with being LTFU and likelihood of accepting care post-outreach. RESULTS: Out of 1269 patients with advanced AMD, 105 (8.3%) did not return for recommended eye care. Patients LTFU were generally older (89.2 ± 8.9 years vs. 87.2 ± 8.5 years, p = 0.02) and lived farther from the clinic (25 ± 43 miles vs. 17 ± 30 miles, p = 0.009). They also had a higher rate of advanced dry AMD (26.7% vs. 18.5%, p = 0.04) and experienced worse vision in both their better-seeing (0.683 logMAR vs. 0.566 logMAR, p = 0.03) and worse-seeing (1.388 logMAR vs. 1.235 logMAR, p = 0.04) eyes. Outreach by a telehealth extender reached 62 patients (59%), 43 through family members or healthcare proxies. Half of the cases where a proxy was contacted revealed that the patient in question had died. Among those contacted directly, one third expressed willingness to resume eye care (20 patients), with 11 scheduling appointments (55%). Despite only two patients returning for in-person eye care through the intervention, the LTFU rate halved to 4.4% by accounting for those patients who no longer needed eye care at the practice. CONCLUSIONS: There is a substantial risk that older patients with advanced AMD will become LTFU. Targeted telephone outreach can provide a pathway for vulnerable patients to return to care.

RESUMO

BACKGROUND & AIMS: A recent panel of international experts proposed the disease acronym metabolic (dysfunction)-associated fatty liver disease (MAFLD) in lieu of nonalcoholic fatty liver disease (NAFLD). We aimed to estimate the burden of and risk factors for NAFLD and MAFLD, and to examine the concordance between definitions in a Veterans population. METHODS: We conducted a cross-sectional study among randomly selected patients within primary care at the Houston Veterans Affairs (VA) facility. Participants completed a survey, provided blood, and underwent Fibroscan. In the absence of heavy alcohol, hepatitis C virus and hepatitis B virus, a controlled attenuation parameter median ≥290 dB/m was used to define NAFLD, whereas MAFLD was defined as controlled attenuation parameter median ≥290 dB/m and either body mass index ≥25 kg/m2 or diabetes, or 2 or more of the following: hypertension, high triglycerides, low high-density lipoprotein cholesterol, and high low-density lipoprotein cholesterol. RESULTS: The mean age of participants was 50.9 years, 55.4% were women, 42.8% were white, and 43.8% were Black. The prevalence of NAFLD was 40.6% (82/202). All 82 patients with NAFLD had a body mass index ≥25 kg/m2, and therefore met our criteria for MAFLD (ie, 100% concordance). Compared with patients with no metabolic trait, patients with ≥3 traits had a 48-fold (adjusted odds ratio, 47.6; 95% confidence interval, 11.3-200) higher risk of NAFLD/MAFLD. Overall, 19 participants (9.4% of the total, 15.9% of those with NAFLD) had at least moderate fibrosis. CONCLUSIONS: NAFLD was present in 40% of Veterans registered in primary care; 9.4% of veterans had at least moderate hepatic fibrosis, with most having concurrent NAFLD. There was perfect concordance between NAFLD and the alternative MAFLD definition.

RESUMO

RATIONALE & OBJECTIVE: Sodium/glucose cotransporter 2 (SGLT2) inhibitors are recommended for type 2 diabetes mellitus (T2DM) in patients with chronic kidney disease (CKD) or atherosclerotic cardiovascular disease (ASCVD). We evaluated factors associated with SGLT2 inhibitor prescription, disparities by race and sex, and facility-level variation in prescription patterns. STUDY DESIGN: Retrospective cohort. SETTING & PARTICIPANTS: A national sample of US veterans with comorbid T2DM, CKD, and ASCVD with a primary care visit between January 1 and December 31, 2020. EXPOSURE: Race, sex, and individual Veterans Affairs (VA) location. OUTCOME: SGLT2 inhibitor prescription. ANALYTICAL APPROACH: Multivariable logistic regression assessed associations of race and sex with SGLT2 inhibitor prescription. Facility-level variation in SGLT2i prescription was quantified by median rate ratios (MRR), which express the likelihood that 2 randomly selected facilities differ in their use of SGLT2 inhibitor among similar patients. RESULTS: Of 174,443 patients with CKD, T2DM, and ASCVD, 20,024 (11.5%) were prescribed an SGLT2 inhibitor. Lower odds of SGLT2 inhibitor prescription were seen in Black or African American patients compared with White patients (OR, 0.87 [95% CI, 0.83-0.91]) and among women compared with men (OR, 0.59 [95% CI 0.52-0.67]). The adjusted MRR for SGLT2 inhibitor prescription was 1.58 (95% CI 1.48-1.67) in the total cohort, indicating an unexplained 58% variation in treatment between VA facilities, independent of patient and facility characteristics. Facility-level variation was evaluated among Black or African American patients (MRR, 1.55 [95% CI 1.41-1.68]), White patients (MRR, 1.57 [95% CI 1.47-1.66]), women (MRR, 1.40 [95% CI 1.28-1.51]), and men (MRR, 1.57 [95% CI 1.48-1.67]). LIMITATIONS: Albuminuria was not assessed. CONCLUSIONS: Prescription for SGLT2 inhibitors was low among likely eligible patients, with evident disparities by sex and race and between individual VA facilities. Efforts are needed to study and address the reasons for these disparities to improve equitable adoption of these important medications.

RESUMO

The cornea is a hormone-responsive tissue that responds to changing levels of female sex hormones. This review focuses on the structural and functional changes in the human cornea associated with the hormonal milestones of menarche, pregnancy, and menopause, as well as consequences stemming from the use of exogenous sex hormones for fertility control and replacement. Articles were identified by searching PubMed without language or region restrictions. The primary outcomes evaluated were changes in central corneal thickness (CCT), intraocular pressure (IOP), and quality of the ocular tear film. The potential impact of hormone-associated changes on the diagnosis and surgical management of common eye diseases, as well as the potential use of sex hormones as therapeutic agents is also considered. Understanding the physiological effects of female sex hormones on the cornea is important because that knowledge can shape the management decisions physicians and women face about ocular health across their life stages.

RESUMO

BACKGROUND: This study compares the visual and anatomical outcomes for the eyes of patients who developed sequential neovascular age-related macular degeneration (nAMD), both at the time of diagnosis and at one year after treatment. METHODS: The study comprised a retrospective case series of 52 patients whose eyes were diagnosed sequentially with nAMD. All eyes were treated with three monthly loading doses of anti-vascular endothelial growth factor agents, followed by further intravitreal injections, as required. Baseline characteristics and outcomes at one year after diagnosis and initial treatment were compared between first and second eyes and included visual acuity (VA), central macular thickness (CMT), and pigment epithelial detachment (PED) height on optical coherence tomography (OCT) imaging. RESULTS: VA at diagnosis was better for second eyes compared with first eyes to develop nAMD (logMAR 0.68 ± 0.51 versus logMAR 0.41 ± 0.34, P = 0.002) and remained so at one year (logMAR 0.61 ± 0.60 versus logMAR 0.42 ± 0.37, P = 0.041). Similarly, PED height at diagnosis was higher in first eyes (225 ± 176 µm versus 155 ± 144 µm, P = 0.003) and also at one year (188 ± 137 µm versus 140 ± 112 µm, P = 0.019). Whereas most patients reported symptoms at first eye diagnosis (71.2%), half as many second eyes were symptomatic (28.8%, P < 0.001). Significantly more symptomatic first eyes experienced visual distortions (32.4% versus 13.3%) or scotomas (29.4% versus 6.7%), compared with a less specific visual complaint of blurry vision (38.2% versus 80.0%, P = 0.006). CONCLUSIONS: Compared with first eyes to develop nAMD, second eyes tended to have better vision, smaller PED heights, and fewer symptoms likely because monitoring permitted earlier diagnosis.

RESUMO

PURPOSE: We report two cases of optic nerve pathology after the administration of the Pfizer-BioNTech and AstraZeneca-Oxford COVID-19 vaccines, respectively, and describe the implications for management of post-vaccination central nervous system (CNS) inflammation. CASE REPORTS: A 69-year-old woman presented with bilateral optic nerve head oedema, 16 days after the second dose of the Pfizer-BioNTech vaccine. She was diagnosed with post-vaccination CNS inflammatory syndrome and was treated for five days with intravenous methylprednisolone at a dose of 1 gram per day. Her optic disc swelling improved, and her vision stabilised. A 32-year-old woman presented six days after her first dose of the AstraZeneca-Oxford vaccine with two days of sudden onset of progressive blurring of vision in her left eye. Posterior segment examination revealed left optic disc swelling, and an MRI of the brain, orbit, and cervical spine was significant for left optic nerve enhancement. The patient was diagnosed with a unilateral post-vaccination optic neuritis. She was treated with a three-day course of intravenous methylprednisolone followed by oral prednisone. Her optic disc swelling and visual field improved, and she recovered 6/6 vision. CONCLUSIONS: Clinicians and patients should be aware of the potential for post-vaccination CNS inflammatory syndromes associated with COVID-19 vaccine administration. Neuroimaging and cerebrospinal fluid analysis may aid in the diagnosis of the cause of vision loss. Further studies are needed to evaluate the spectrum and frequency of optic nerve involvement associated with COVID-19 vaccination.

RESUMO

Purpose: To assess the effectiveness and financial implications of employing a telehealth physician extender program to re-engage patients with diabetic retinopathy (DR) who are lost to follow-up (LTF). Methods: Established patients with DR unevaluated in the prior 12 months were identified as LTF, and randomized to receive a recall intervention or standard operating procedure (SOP). For the intervention, a telehealth physician extender performed outbound calls, offering each patient a symptom screening questionnaire following a physician-directed escalation pathway and assistance in scheduling a return appointment. All patients retained the ability to schedule an appointment by means of SOP. Appointment schedule and adherence rates were assessed 30 days after a 6-week intervention period. Call times were digitally measured to estimate intervention labor cost. Results: Four hundred twenty-five of 2,514 established patients with DR were LTF (17%). One hundred fifty-seven patients were assigned to the intervention group; the remaining 268 formed the SOP group. Sixty-six outbound calls reached patients (42%). At the time of program assessment, the intervention group demonstrated a higher rate of appointment scheduling (31% vs. 14%, p < 0.001) and adherence (14% vs. 7%, p = 0.020). The measured call duration was 2.3 ± 1.9 min, yielding an estimated cost of US$4.70 per appointment scheduled. Conclusion: Re-engagement by a telehealth physician extender improves the rate at which patients with DR return for eye care, and can be done at a reasonable cost. This method of improving adherence with follow-up should be readily translatable to other health care settings.

RESUMO

PURPOSE: To evaluate the effect of optic nerve sheath fenestration (ONSF) on the rate of visual function improvement in patients with pseudotumor cerebri syndrome (PTCS). METHODS: Retrospective chart review of patients with PTCS who underwent ONSF between 1998 and 2017. Visual function was evaluated by evaluating visual field (VF), mean deviation (MD), retinal nerve fiber layer (RNFL) thickness, papilledema grade, and visual acuity (VA) prior to and after ONSF. RESULTS: Seventeen female patients aged 17 to 36 years underwent unilateral ONSF. Follow-up averaged 40.1 months. VF MD improved steadily in both eyes up to 12 months. Average RNFL thickness improved in the operated eye from 347 ± 166 mm to 92 ± 27 mm (p < .001) and the non-operated eyes from 306 ± 165 mm to 109 ± 46 mm (p < .001). The grade of papilledema improved in the operated eye from 3.3 ± 1.3 to 0.3 ± 0.7 and the non-operated eye from 3.0 ± 1.6 to 0.18 ± 0.4. There was an exponential rate of improvement in papilledema and RNFL thickness, with the greatest improvement occurring within the first 30 days. Average visual acuity remained intact in both eyes before and after surgery. CONCLUSIONS: ONSF in appropriately selected patients leads to rapid improvement in papilledema and a steady recovery in VF.

RESUMO

PURPOSE: To prevent vision loss, it is important to monitor patients with age-related macular degeneration (AMD) for the development of choroidal neovascularization. The coronavirus disease 2019 (COVID-19) pandemic caused many patients to miss or delay visits. To offset those gaps in care, providers utilized telehealth (TH) to evaluate patients for symptoms of disease progression and provide health education on the importance of continuous monitoring. METHODS: This study evaluates the impact of TH encounters on the rate of return for recommended in-person examinations for 1103 patients with non-neovascular (dry) AMD seen in an outpatient ophthalmology clinic in 2019 and due for return evaluation after the outbreak of COVID-19 in 2020. Logistic regression analysis was used to identify demographic, clinical, and sociomedical factors associated with TH utilization and in-person return. RESULTS: 422 patients (38%) utilized TH during the study period. Patients who completed a TH encounter were more likely to return for an in-person examination as compared with those who did not receive TH (OR: 1.8, CI 95%: 1.4-2.3, P < 0.001). Completing a TH visit was associated with the detection of new wet AMD (OR: 3.3, 95% CI 1.04-10.6, P = 0.043), as well as with an earlier return for those patients who were found to have disease progression (62 ± 54 days vs. 100 ± 57 days, P = 0.049). CONCLUSION: Completing a TH visit increased the rate at which patients with dry AMD returned for recommended in-person eye examinations. In many cases, this permitted the earlier detection of wet AMD, which is linked with achieving better outcomes.

RESUMO

INTRODUCTION: Adrenal mass management guidelines are insufficiently applied, and timeliness of treatment is unknown. We evaluated missed opportunities to promptly diagnose and treat adrenal tumors that ultimately required adrenalectomy. METHODS: From the Veterans Affairs Corporate Data Warehouse, we identified patients who underwent adrenalectomy (2010-2016) in the South-Central Veterans Affairs HealthCare Network and reviewed their records. Diagnostic timeliness was assessed by the interval between initial (index) imaging with adrenal abnormality and the next diagnostic step. Workup was defined as early (interval ≤6 mo) or late (>6 mo). Adrenalectomy was considered prompt when the interval between index imaging and adrenalectomy was ≤12 mo and delayed when this was >12 mo. We quantified diagnostic and treatment delays and assessed factors associated with delayed adrenalectomy. RESULTS: During the study period, 84 patients underwent adrenalectomy: male (86.9%), White (57.1%), with a mean age of 58.7 y (±8.8). Of those, 25 (29.8%) had late workup, and 36 (42.9%) had delayed surgery (median interval: 44 mo, range 14-282). Late hormonal workup occurred in 24 of 36 (66.7%) patients with delayed surgery, compared with one of 48 (2.1%, P < 0.001) with prompt surgery. CONCLUSIONS: Missed opportunities in prompt diagnosis and treatment were common in patients with adrenal masses ultimately requiring adrenalectomy. Late hormonal workup is associated with delayed adrenalectomy. Interventions are needed to aid clinicians to recognize the presence, promptly evaluate, and make guideline-informed decisions on the management of an adrenal mass.

RESUMO

The Judas technique is often used in control or eradication of particular vertebrate pests. The technique exploits the tendency of individuals to form social groups. A radio collar is affixed to an individual and its subsequent monitoring facilitates the detection of other conspecifics. Efficacy of this technique would be improved if managers could estimate the probability that a Judas individual would detect conspecifics. To calculate this probability, we estimated association rates of Judas individuals with other Judas individuals, given the length of time the Judas has been deployed. We developed a simple model of space-use for individual Judas animals and constrained detection probabilities to those specific areas. We then combined estimates for individual Judas animals to infer the probability that a wild individual could be detected in an area of interest via Judas surveillance. We illustrated the method by using data from a feral goat eradication program on Isla Santiago, Galápagos, and a feral pig eradication program on Santa Cruz Island, California. Association probabilities declined as the proximity between individual areas of use of a Judas pair decreased. Unconditional probabilities of detection within individual areas of use averaged 0.09 per month for feral pigs and 0.11 per month for feral goats. Probabilities that eradication had been achieved, given no detections of wild conspecifics, and an uninformative prior probability of eradication were 0.79 (90% CI 0.22-0.99) for feral goats and 0.87 (90% CI 0.44-1.0) for feral pigs. We envisage several additions to the analyses used that could improve estimates of Judas detection probability. Analyses such as these can help managers increase the efficacy of eradication efforts, leading to more effective effects to restore native biodiversity.


La técnica de Judas se usa con frecuencia en el control de ciertas plagas de vertebrados. La técnica se aprovecha de la tendencia a formar grupos sociales que tienen los individuos. Un radio-collar es colocado en uno de los individuos y el monitoreo subsecuente facilita la detección de otros miembros de la misma especie. La eficacia de esta técnica mejoraría si los gestores pudieran estimar la probabilidad que tiene un Judas de detectar a miembros de su especie. Para calcular esta probabilidad, estimamos las tasas de asociación de los Judas con otros Judas, dado el tiempo que el Judas ha sido enviado. Desarrollamos un modelo simple del uso del espacio para animales Judas individuales y limitamos las probabilidades de detección a esas áreas específicas. Después combinamos los estimados de un animal Judas individual para inferir la probabilidad de que un individuo silvestre pudiera ser detectado en un área de interés mediante la vigilancia Judas. Ilustramos el método con los datos de un programa de erradicación de cabras ferales en Isla Santiago, las Galápagos, y uno de cerdos ferales en la Isla de Santa Cruz, California. Las probabilidades de asociación declinaron conforme disminuyó la proximidad entre las áreas individuales de uso de un par de Judas. Las probabilidades incondicionales de detección dentro de las áreas individuales de uso promediaron 0.09 por mes para los cerdos ferales y 0.11 por mes para las cabras ferales. Las probabilidades de que se había logrado la erradicación, dada la ausencia de detecciones de miembros de la misma especie y una mal informada probabilidad previa de erradicación, fueron de 0.79 (90% CI 0.22 - 0.99) para las cabras ferales y 0.87 (90% CI 0.44 - 1.0) para los cerdos ferales. Contemplamos varias adiciones al análisis que usamos que podrían mejorar los estimados de la probabilidad de detección de Judas. Análisis como este pueden ayudar a los gestores a incrementar la efectividad de los esfuerzos de erradicación, lo que resulta en efectos más efectivos para restaurar la biodiversidad nativa.

RESUMO

PURPOSE: We investigated facility-level variation in the use and adherence with antiplatelets and statins among patients with premature and extremely premature ASCVD. METHODS: Using the 2014-2015 nationwide Veterans wIth premaTure AtheroscLerosis (VITAL) registry, we assessed patients with premature (age at first ASCVD event: males < 55 years, females < 65 years) and extremely premature ASCVD (< 40 years). We examined frequency and facility-level variation in any statin, high-intensity statin (HIS), antiplatelet use (aspirin, clopidogrel, ticagrelor, prasugrel, and ticlopidine), and statin adherence (proportion of days covered ≥ 0.8) across 130 nationwide VA healthcare facilities. Facility-level variation was computed using median rate ratios (MRR), a measure of likelihood that two random facilities differ in use of statins or antiplatelets and statin adherence. RESULTS: Our analysis included 135,703 and 7716 patients with premature and extremely premature ASCVD, respectively. Across all facilities, the median (IQR) prescription rate of any statin therapy, HIS therapy, and antiplatelets among patients with premature ASCVD was 0.73 (0.70-0.75), 0.36 (0.32-0.41), and 0.77 (0.73-0.81), respectively. MRR (95% CI) for any statin use, HIS use, and antiplatelet use were 1.53 (1.44-1.60), 1.58 (1.49-1.66), and 1.49 (1.42-1.56), respectively, showing 53, 58, and 49% facility-level variation. The median (IQR) facility-level rate of statin adherence was 0.58 (0.55-0.62) and MRR for statin adherence was 1.13 (1.10-1.15), showing 13% facility-level variation. Similar median facility-level rates and variation were observed among patients with extremely premature ASCVD. CONCLUSIONS: There is suboptimal use and significant facility-level variation in the use of statin and antiplatelet therapy among patients with premature and extremely premature ASCVD.

RESUMO

PURPOSE: Statin-associated side effects (SASEs) can limit statin adherence and present a potential barrier to optimal statin utilization. How standardized reporting of SASEs varies across medical facilities has not been well characterized. METHODS: We assessed facility-level variation in SASE reporting among patients with atherosclerotic cardiovascular disease receiving care across the Veterans Affairs (VA) healthcare system from October 1, 2014, to September 30, 2015. The facility rates for SASE reporting were expressed as cases per 1000 patients with ASCVD. Facility-level variation was determined using hierarchical regression analysis to calculate median rate ratios (MRR [95% confidence interval]) by first using an unadjusted model and then adjusting for patient, provider, and facility characteristics. RESULTS: Of the 1,248,158 patients with ASCVD included in our study across 130 facilities, 13.7% had at least one SASE reported. Individuals with a history of SASE were less likely to be on a statin at follow-up compared with those without SASE (72.0% vs 80.8%, p < 0.01). The median (interquartile range) facility rate of SASE reported was 140.5 (109.4-167.7) cases per 1000 patients with ASCVD. Significant facility-level variation in the rate of SASE reported was observed: MRR 1.38 (1.33-1.44) in the unadjusted model and MRR 1.56 (1.47-1.65) in the adjusted model. CONCLUSION: Significant facility-level variation in SASE reporting was found within the VA healthcare system suggesting room for improvement in standardized documentation of SASEs among medical facilities. This has the potential to lead to improvement in statin utilization.

RESUMO

BACKGROUND: This study describes the implementation of an electronic medical record (EMR)-based initiative aimed at identifying and reducing the number of patients with diabetic retinopathy (DR) lost to follow-up (LTF). METHOD: Providers were enlisted to review the EMRs and re-engage patients with DR seen 1 year prior and who had not returned for care within the past 6 months. Binary logistic regression analysis was used to identify demographic, clinical and sociomedical factors associated with being LTF, as well as those predictive of re-engagement. RESULTS: Out of 673 patients with DR, 78 (12%) were identified as LTF. Patients LTF were more likely to be younger (p = 0.001) and have poorly controlled haemoglobin A1c (HbA1c ≥ 8%, p = 0.04) and cholesterol (LDL ≥ 100 mg/dL, p < 0.001) levels. These patients were also more likely to have completed fewer ophthalmology appointments (p < 0.001), and less likely to have had retinal imaging within the last year (p < 0.001). Charts reviewed 1 month after the EMR-based initiative revealed that 22 patients (28%) had been successfully re-engaged by providers, while 56 patients (72%) remained LTF. History of prior treatment for DR was associated with re-engagement by providers (p = 0.04). One month following the provider-based intervention, the LTF rate dropped to 8.3%, and by 1 year only 3.6% of the patients remained LTF. CONCLUSIONS: Electronic medical record-based tools can successfully identify DR patients as being LTF, offering an opportunity for providers to re-engage patients in a timely manner. Future studies are needed to determine the long-term impact of patient re-engagement on DR outcomes and efficiency of clinical practice.

RESUMO

PURPOSE: To analyze long-term outcomes in a large cohort of patients with acute peripheral facial palsy (APFP). METHODS: Hospital-based, cross-sectional study. Data were abstracted from the electronic medical record. Time to recovery was assessed with Kaplan-Meier survival analyses. Binary logistic regression analysis was used to identify factors associated with outcome. RESULTS: Three hundred seventy-two patients with APFP seen at a tertiary hospital between February 2015 and March 2021 were analyzed. Seasonal variation of APFP peaked in the early fall (September 29) and had a peak-to-low ratio of 1.36 (R 2 = 0.329, p < 0.001). Patients who tested positive for Lyme disease (10%) had an earlier peak (July 16) compared with those who were negative (October 15). Eighty-seven percent of patients had complete recovery (averaging 64 ± 61 days). Patients, with higher House-Brackmann (H-B) grades at presentation took longer to recover, were more likely to have aberrant regeneration and had lower final rates of recovery compared with those with lower H-B grades (χ 2 = 12.03, p < 0.001). Of the patients with residual palsies, 70% had evidence of aberrant regeneration, and nearly half of those had hemifacial spasm. CONCLUSIONS: Most patients with APFP achieve complete recovery within 1 year, including those positive for Lyme. More severe palsy at presentation portends a worse outcome.

RESUMO

OBJECTIVES: We examined associations among three measures of caregiver experiences (i.e., positive aspects of caring [PAC], caregiver burden, and mutuality) in 228 dyads involving persons with dementia (PWD) and their informal caregivers. The associations between predisposing, enabling, and need factors and each of these three measures of caregiver experiences were also examined. METHODS: We used baseline data from a randomized controlled trial of a psychosocial intervention aimed at preventing aggression in PWD. Associations among PAC, caregiver burden, and mutuality were examined. The Behavioral Model of Health Services Utilization guided the selection of predisposing, enabling, and need components. RESULTS: Enabling characteristics (e.g., race/ethnicity, caregiver education and employment and PWD education) and most predisposing characteristics (e.g., caregiver age, PWD age, relationship type) were not associated with any caregiving experience measures. Need characteristics (e.g., levels of memory and functional impairment, behavioral problems, depression, pleasant events) were associated with the caregiving experience. CONCLUSIONS: Bivariate correlations between PAC, caregiver burden, and mutuality were between -0.20 and -0.58. Predisposing, enabling, and need factors were differentially associated with outcomes, with need characteristics being most frequently associated with various aspects of caregiving. CLINICAL IMPLICATIONS: Assessment of both positive and negative aspects of caregiving is important. Particular attention to depression and interventions that improve depressive symptoms may increase PAC and mutuality and reduce caregiver burden.

RESUMO

BACKGROUND: A large number of studies have evaluated the pharmacology, safety, and/or efficacy of bismuth subsalicylate for the relief of common gastrointestinal symptoms, diarrhea and vomiting due to acute gastroenteritis. In addition, short-term (48 h) medication with bismuth subsalicylate is known to be effective against infectious gastroenteritis such as travelers' diarrhea. AIMS: Previous studies have documented the bacteriostatic/bactericidal effects of bismuth subsalicylate against a variety of pathogenic gastrointestinal bacteria. However, meta-analyses of the clinical efficacy of bismuth subsalicylate for both prevention and treatment of travelers' diarrhea have not yet been published. METHODS: A total of 14 clinical studies (from 1970s to 2007) comprised the core data used in this assessment of efficacy of bismuth subsalicylate against infectious (including travelers') diarrhea. These studies allowed for statistical meta-analyses regarding prevention (three travelers' diarrhea studies) and treatment of infectious diarrhea (11 studies [five travelers' diarrhea]). RESULTS: The results show that subjects treated with bismuth subsalicylate for up to 21 days have 3.5 times greater odds of preventing travelers' diarrhea compared with placebo (95% CI 2.1, 5.9; p < 0.001). In addition, subjects with infectious diarrhea treated with bismuth subsalicylate had 3.7 times greater odds of diarrhea relief (recorded on diaries as subjective symptomatic improvement) compared to those receiving placebo (95% CI 2.1, 6.3; p < 0.001). CONCLUSIONS: This systematic review and meta-analysis suggests that bismuth subsalicylate can be beneficial for those at risk or affected by food and waterborne diarrheal disease such as traveler's (infectious) diarrhea, and may decrease the risk of inappropriate antibiotic utilization.

RESUMO

BACKGROUND: COVID-19, a highly contagious respiratory virus, presents unique challenges to ophthalmology practice as a high-volume, office-based specialty. In response to the COVID-19 pandemic, many operational changes were adopted in our ophthalmology clinic to enhance patient and provider safety while maintaining necessary clinical operations. The aim of this study was to evaluate how measures adopted during the pandemic period affected retina clinic performance and patient satisfaction, and to model future clinic flow to predict operational performance under conditions of increasing patient and provider volumes. METHODS: Clinic event timestamps and demographics were extracted from the electronic medical records of in-person retina encounters from March 15 to May 15, 2020 and compared with the same period in 2019 to assess patient flow through the clinical encounter. Patient satisfaction was evaluated by Press Ganey patient experience surveys obtained from randomly selected outpatient encounters. A discrete-events simulation was designed to model the clinic with COVID-era restrictions to assess operational performance under conditions of increasing patient and provider volumes. RESULTS: Retina clinic volume declined by 62 % during the COVID-19 health emergency. Average check-in-to-technician time declined 79 %, total visit length declined by 46 %, and time in the provider phase of care declined 53 %. Patient satisfaction regarding access nearly doubled during the COVID-period compared with the prior year (p < 0.0001), while satisfaction with overall care and safety remained high during both periods. A model incorporating COVID-related changes demonstrated that wait time before rooming reached levels similar to the pre-COVID era by 30 patients-per-provider in a 1-provider model and 25 patients-per-provider in a 2-provider model (p < 0.001). Capacity to maintain distancing between patients was exceeded only in the two 2-provider model above 25 patients-per-provider. CONCLUSIONS: Clinic throughput was optimized in response to the COVID-19 health emergency. Modeling these clinic changes can help plan for eventual volume increases in the setting of limits imposed in the COVID-era.
