Blink Lagophthalmos in Graves Orbitopathy.

PURPOSE: To investigate the relationship between the kinematics of spontaneous blinks and the anterior area of the levator palpebrae superioris muscle in patients with Graves orbitopathy (GO). METHODS: This is a case-control study. The authors measured the margin reflex distance of the upper eyelid (margin reflex distance 1), the kinematics of spontaneous blinks, and the anterior area of levator palpebrae superioris muscle in CT coronal scans of patients with Graves upper eyelid retraction (GO) and a control group. The eye with the greatest margin reflex distance 1 was selected for analysis in each group. RESULTS: A total of 68 participants were included, with 36 in the GO group and 32 in the control group. In the GO group, the mean margin reflex distance 1 measured 6.5 mm, while in the control group, it was 3.9 mm. Almost all parameters related to the closing phase of spontaneous blinking activity, including amplitude, velocity, blinking rate, and interblink time, did not differ between the two groups. However, the effectiveness of the blink's amplitude (ratio of blink amplitude to margin reflex distance 1) and the main sequence (relationship between amplitude and velocity) were significantly reduced in the GO group compared with the control group. The area of the levator palpebrae superioris muscle was significantly larger in GO than in controls, with 71.4% of patients' muscles outside of the maximum range of the controls. CONCLUSIONS: In patients with GO, there is a reduction in blinking effectiveness, also known as blink lagophthalmos, which is a factor in the common occurrence of ocular surface symptoms. The increase in velocity with amplitude is also reduced in GO.

Digital empathy in behaviour change interventions: A survey study on health coach responses to patient cues.

Introduction: Digital health coaching interventions for behaviour change (BC) are effective in addressing various health conditions. Implementing these requires accurate descriptions of components and health coaches (HC) delivery methods, alongside understanding patients' perceptions of these interactions. The HC-patient relationship significantly influences BC outcomes. Here, empathy is an important driver that enables HCs to offer tailored advice that resonates with patients' needs, fostering motivation. Yet, defining and measuring empathy remains a challenge. In this study, we draw on various BC frameworks and Pounds' empathy appraisal approach to categorise HCs responses to patient cues and explore the interplay between empathy and BC. Methods: Using a two-round survey, we collected responses from 11 HCs to 10 patient messages from the Bump2Baby and Me trial in a simulated interaction. We analysed 88 messages to identify empathic responses and behaviour change techniques. Results: Patients' implicit empathy opportunities showed higher response rates than explicit ones. HCs prioritised positive reinforcement and employed various strategies to achieve similar objectives. The most common empathic response was 'Acceptance' for patients' implicit positive expressions of self-judgement. HCs emphasised relatedness-support and competence-promoting techniques for implicit negative feelings and judgements, such as 'Show unconditional regard' and 'Review behaviour goals', and 'Action planning and Problem-solving' techniques to address explicit negative appreciations and feelings. Conclusion: The use of different techniques with the same objective highlights the complexity of BC interactions. Further research is needed to explore the impact of this variability on patient outcomes and programme fidelity.

Apical bleeding: a rare cause of blindness after orbital decompression / Sangramento apical: uma causa rara de cegueira pós descompressão orbitária

ABSTRACT Orbital decompression is widely performed for the management of proptosis for cosmetic and functional cases of Graves orbitopathy. The main side effects include dry eye, diplopia, and numbness. Blindness after orbital decompression is extremely rare. The mechanisms of vision loss after decompression are not well described in the literature. Considering the devastating effect and rarity of this complication, this study presented two cases of blindness after orbital decompression. In both cases, vision loss was provoked by slight bleeding in the orbital apex.

RESUMO A descompressão orbitária é uma cirurgia amplamente empregada para correção da proptose em casos cosméticos e funcionais da orbitopatia de Graves. Os principais efeitos colaterais induzidos pela descompressão são olho seco, diplopia e parestesias. Amaurose pós descompressão é uma complicação extremamente rara e cujos mecanismos são pouco discutidos na literatura. Considerando o efeito devastador representado pela perda visual e a escassez de relatos dessa complicação, os autores apresentam dois relatos de amaurose após descompressão orbitária. Nos dois casos a perda visual ocorreu devido a sangramento de pequena monta no ápice orbitário.

Revisiting the orbital complications of acute rhinosinusitis

Abstract Objective: The present study revisited three classification systems of orbital complications of acute rhinosinusitis (ARS) (Chandler, Mortimore & Wormald, and Velasco e Cruz & Anselmo-Lima) and observed which of them presented the best clinical applicability. Methods: Clinical data and CT scan findings of patients with orbital infection were retrospectively collected. To compare the three classification systems, we revised and graded all CT images accordingly, and divided the patients into four groups: Eyelid cellulitis (EC), orbital cellulitis (OC), subperiosteal abscess (SA), and orbital abscess (OA). The groups were compared regarding the presence of sinus opacification, the need for hospitalization and/or surgical treatment, and the presence of further complications/sequelae. Results: 143 patients were included. The median number of sinuses involved in patients in the OC, SA, and OA groups was 2.0. ARS was rarely associated with signs of EC (present in both Chandler's and Mortimore & Wormald's classifications. The hospitalization rate was significantly lower in the EC group compared to the other three groups. Surgery was performed in all cases in the OA group, in 58.1% in the SA group, 19.4% in the OC group, and 12.5% in the EC group (p-value < 0.0001 ). Complications were present at higher rates in the OA group compared to the other three groups. Conclusions: ARS was rarely associated with Eyelid Cellulitis. The stratification in the other three groups showed to be clinically relevant. Velasco e Cruz & Anselmo-Lima's classification system proved valid, simple, and effective for categorizing orbital complications of ARS. Level of evidence: 3.

On-farm evaluation of models to predict herbage intake of dairy cows grazing temperate semi-natural grasslands.

The objective of the present on-farm study was to evaluate the adequacy of existing models in predicting the pasture herbage DM intake (PDMI) of lactating dairy cows grazing semi-natural grasslands. The prediction adequacy of 13 empirical and semi-mechanistic models, which were predominantly developed to represent stall-fed cows or cows grazing high-quality pastures, were evaluated using the mean bias, relative prediction error (RPE), and partitioning of mean square error of prediction, where models with an RPE ≤ 20% were considered adequate. The reference dataset comprised n = 233 individual animal observations from nine commercial farms in South Germany with a mean milk production, DM intake, and PDMI (arithmetic means ± one SD) of 24 kg/d, (±5.6), 21 kg/d (±3.2), and 12 kg/d (±5.1), respectively. Despite their adaptation to grazing conditions, the behaviour-based and semi-mechanistic grazing-based models had the lowest prediction adequacy among the evaluated models. Their underlying empirical equations likely did not fit the grazing and production conditions of low-input farms using semi-natural grasslands for grazing. The semi-mechanistic stall-based model Mertens II with slight modifications achieved the highest and a satisfactory modelling performance (RPE = 13.4%) when evaluated based on the mean observed PDMI, i.e., averaged across animals per farm and period (n = 28). It also allowed for the adequate prediction of PDMI on individual cows (RPE = 18.5%) that were fed < 4.8 kg DM of supplement feed per day. Nevertheless, when used to predict PDMI of individual animals receiving a high supplementation level, the model Mertens II also did not meet the threshold for an acceptable adequacy (RPE = 24.7%). It was concluded that this lack of prediction adequacy for animals receiving greater levels of supplementation was due to a lack of modelling precision, which mainly could be related to inter-animal and methodological limitations such as the lack of individually measured supplement feed intake for some cows. The latter limitation is a trade-off of the on-farm research approach of the present study, which was chosen to represent the range in feed intake of dairy cows across the diverse low-input farming systems using semi-natural grasslands for grazing.

Computed tomography and magnetic resonance imaging of an unusual intraconal orbital osteoma.

We report the case of a 64-year-old male patient with a 5 month history of proptosis, motility limitation and vision loss in OD. Visual acuity (VA) was 20/200 in OD and 20/20 in OS. CT showed a large, round, intraconal lesion, with bony density and no apparent connection to adjacent orbital walls. MRI showed a T1-weighted hypointense lesion surrounded by a contrast enhancing capsule. The orbital tumor was excised through a lateral orbitotomy revealing a nodular, round, osseous structure. Histological examination disclosed well-formed lamellar bone trabeculae, with no necrosis or mitosis figures. Immunohistochemical staining was negative for MDM2 and CDK4. After 3 years, there was no evidence of tumor recurrence and VA had improved to 20/30. Intraconal osteomas with no clear attachment to orbital walls are extremely rare. We are aware of a few reported cases in the lid, hand, thigh, tongue, pterygopalatine fossa and brain. To the authors' knowledge, this is the first report in English literature of an orbital intraconal osteoma without any visible relation to the orbital walls.

PACAP-PAC1R modulates fear extinction via the ventromedial hypothalamus.

Exposure to traumatic stress can lead to fear dysregulation, which has been associated with posttraumatic stress disorder (PTSD). Previous work showed that a polymorphism in the PACAP-PAC1R (pituitary adenylate cyclase-activating polypeptide) system is associated with PTSD risk in women, and PACAP (ADCYAP1)-PAC1R (ADCYAP1R1) are highly expressed in the hypothalamus. Here, we show that female mice subjected to acute stress immobilization (IMO) have fear extinction impairments related to Adcyap1 and Adcyap1r1 mRNA upregulation in the hypothalamus, PACAP-c-Fos downregulation in the Medial Amygdala (MeA), and PACAP-FosB/ΔFosB upregulation in the Ventromedial Hypothalamus dorsomedial part (VMHdm). DREADD-mediated inhibition of MeA neurons projecting to the VMHdm during IMO rescues both PACAP upregulation in VMHdm and the fear extinction impairment. We also found that women with the risk genotype of ADCYAP1R1 rs2267735 polymorphism have impaired fear extinction.

Urban Water Storage Capacity Inferred From Observed Evapotranspiration Recession.

Water storage plays an important role in mitigating heat and flooding in urban areas. Assessment of the water storage capacity of cities remains challenging due to the inherent heterogeneity of the urban surface. Traditionally, effective storage has been estimated from runoff. Here, we present a novel approach to estimate effective water storage capacity from recession rates of observed evaporation during precipitation-free periods. We test this approach for cities at neighborhood scale with eddy-covariance based latent heat flux observations from 14 contrasting sites with different local climate zones, vegetation cover and characteristics, and climates. Based on analysis of 583 drydowns, we find storage capacities to vary between 1.3 and 28.4 mm, corresponding to e-folding timescales of 1.8-20.1 days. This makes the urban storage capacity at least five times smaller than all the observed values for natural ecosystems, reflecting an evaporation regime characterized by extreme water limitation.

Midostaurin en combinación de quimioterápia como tratamiento de leucémia mieloblástica aguda con mutación FTL3, a propósito de un caso / Midostaurin in combination with chemotherapy as a treatment for acute myeloblastic leukemia with FTL3 mutation, a case report

La leucemia mieloblástica aguda (LMA) es una enfermedad heterogénea caracterizada por el crecimiento descontrolado de precursores mieloides indiferenciados que provoca un fallo medular. Según datos del programa de Vigilancia, Epidemiología y Resultados Finales (SEER) se estima una incidencia anual de 4,2 por cada 100.000 habitantes. El porcentaje de incidencia en menores de 20 años es 5,1% y en personas entre 65-84 años, es 46,5%. La tasa de supervivencia a 5 años varía en función de la edad de los pacientes, siendo en menores de 20 del 67% y en mayores a dicha edad disminuye al 25%. La leucemia mieloide aguda representa el 40% del total de leucemias y la mediana de edad de los pacientes es 65 años. Las alteraciones citogenéticas más frecuentes son: traslocación (8;21), inversión cromosoma 16, traslocación (16;16), trisomía del cromosoma 8, deleciones en los cromosomas 5 y 7, y mutación en el gen FLT3 (13q12), la cual está presente en el 30% de los nuevos diagnósticos. El tratamiento estándar de quimioterapia sigue basándose en el esquema intensivo 3+7 que consiste en citarabina con antraciclinas. El objetivo de las nuevas terapias en LMA es el tratamiento dirigido debido a los avances en el diagnóstico y la tipificación. (AU)

Acute myeloblastic leukemia (AML) is a heterogeneous disease characterized by uncontrolled growth of undifferentiated myeloid precursors leading to bone marrow failure. According to data from the Surveillance, Epidemiology and End Results (SEER) program, the annual incidence is estimated at 4.2 per 100,000 population. The incidence rate in children under 20 years of age is 5.1% and in people between 65-84 years of age, it is 46.5%. The 5-year survival rate varies according to the age of the patients, being 67% in those under 20 years of age and 25% in those older than 20 years of age. Acute myeloid leukemia represents 40% of all leukemias and the median age of the patients is 65 years. The most frequent cytogenetic alterations are: translocation (8;21), inversion of chromosome 16, translocation (16;16), trisomy of chromosome 8 and deletions in chromosomes 5 and 7, mutation in the FLT3 gene (13q12), which is present in 30% of new diagnoses. Standard chemotherapy treatment is still based on the intensive 3+7 scheme consisting of cytarabine with anthracyclines. The focus of new therapies in AML is targeted therapy due to advances in diagnosis and typing. (AU)

Progressive chronic calvarial osteomyelitis in rhino-orbital mucormycosis associated with COVID-19.

We describe two cases of extensive indolent calvarial osteomyelitis after rhino-orbital-mucormycosis in diabetic patients previously diagnosed with COVID-19. Both patients presented with acute rhino-orbital symptoms about one month after being diagnosed with COVID-19. Treatment with intravenous liposomal Amphotericin B and prompt radical surgical debridement was instituted, but calvarial osteomyelitis ensued and persisted chronically despite maintenance of antifungal therapy and partial debridement of necrotic calvarial bone. The patients were discharged to continue antifungal therapy on a day-hospital regime. After more than 8 months of treatment, they remain with radiological signs of osteomyelitis but with no symptoms or intracranial extension of the infection. Calvarial indolent osteomyelitis secondary to mucormycosis is extremely rare, and little is known regarding its treatment. We believe it can be controlled with medical treatment and partial bony debridement although more studies are necessary to better define therapy.

Posicionamiento de la Sociedad Española de Farmacia Clínica, Familiar y Comunitaria sobre telefarmacia: teleatención farmacéutica (TAF) / Position of the Spanish Society of Clinical, Family and Community Pharmacy on telepharmacy: telepharmaceutical telecare (TAF)

Las nuevas tecnologías de la información y comunicación (TIC) están desarrollándose desde hace bastantes años, pero la pandemia de COVID-19 ha acelerado la transformación digital de la sociedad. En el campo de la salud han surgido nuevas actividades y de esta forma términos como telemedicina, teleasistencia o teleconsulta empiezan a ser habituales. Indudablemente suponen un avance, pero tienen el riesgo de deshumanizar el contacto de sanitarios y pacientes.En el campo de la farmacia ha surgido la telefarma cia con unas innegables connotaciones logísticas y comerciales. Desde la Sociedad Española de Farmacia Clínica, Familiar y Comunitaria se prefiere utilizar el término teleatención farmacéutica (TAF), definiéndolo como la práctica farmacéutica asistencial a distancia que utiliza las TIC para complementar la atención farmacéutica presencial que precise el paciente. La TAF incluye la prestación a distancia de algunos servicios profesionales farmacéuticos asistenciales (SPFA). La TAF debe ayudar al farmacéutico comunitario a prestar algunos SPFA, mejorando así la practica farmacéutica clínica sin caer en la deshumanización que la aplicación indiscriminada de las TIC puede producir.
