Background

Symptoms of depression are transdiagnostic heterogenous features frequently assessed in psychiatric disorders, that impact the response to first-line treatment and are associated with higher suicide risk. This study assessed whether severe mental pain could characterize a specific phenotype of severely depressed high-risk psychiatric patients. We also aimed to analyze differences in treatments administered.

Methods

2,297 adult patients (1,404 females and 893 males; mean age = 43.25 years, SD = 15.15) treated in several Italian psychiatric departments. Patients were assessed for psychiatric diagnoses, mental pain, symptoms of depression, hopelessness, and suicide risk.

Results

More than 23% of the patients reported high depression symptomatology and high mental pain (HI DEP/HI PAIN). Compared to patients with lower symptoms of depression, HI DEP/HI PAIN is more frequent among females admitted to an inpatient department and is associated with higher hopelessness and suicide risk. In addition, HI DEP/HI PAIN (compared to both patients with lower symptoms of depression and patients with higher symptoms of depression but lower mental pain) were more frequently diagnosed in patients with personality disorders and had different treatments.

Conclusions

Patients reporting severe symptoms of depression and high mental pain presented a mixture of particular dangerousness (high trait hopelessness and the presence of suicide ideation with more frequency and less controllability and previous suicide behaviors). The presence of severe mental pain may act synergically in expressing a clinical phenotype that is likewise treated with a more complex therapeutic regime than that administered to those experiencing symptoms of depression without mental pain.

Published: August 2022

Inspired by the energy conversion processes through the discrete 120° rotation by ATPase, here we newly developed a multiblock amphiphilic triptycene that can be incorporated into the lipid bilayers. The incorporation was confirmed by microscopy and spectroscopy techniques. We also found that depending on the concentration, multiblock amphiphilic triptycene assembled within the lipid bilayers.
North-South Displacement Effects of Environmental Regulation: The Case of Battery Recycling
Authors: Tanaka Shinsuke , Teshima Kensuke , Verhoogen Eric
Published: August 2022

This study examines the effect of a tightening of the US air quality standard for lead in 2009 on the relocation of battery recycling to Mexico and on infant health in Mexico. In the United States, airborne lead dropped sharply near affected plants, most of which were battery-recycling plants. Exports of used batteries to Mexico rose markedly. In Mexico, production increased at battery-recycling plants relative to comparable industries, and birth outcomes deteriorated within two miles of those plants relative to areas slightly farther away. The case provides a salient example of a pollution-haven effect between a developed and a developing country. (JEL F18, I12, J13, O15, Q51, Q53, Q58)
The COVID-19 Pandemic Disrupted Both School Bullying and Cyberbullying
Authors: Bacher-Hicks Andrew , Goodman Joshua , Green Jennifer Greif , Holt Melissa K.
Published: August 2022

One-fifth of US high school students report being bullied each year. We use internet search data for real-time tracking of bullying patterns as COVID-19 disrupted in-person schooling. We first show that pre-pandemic internet searches contain useful information about actual bullying behavior. We then show that searches for school bullying and cyberbullying dropped 30–35 percent as schools shifted to remote learning in spring 2020. The gradual return to in-person instruction starting in fall 2020 partially returned bullying searches to pre-pandemic levels. This rare positive effect may partly explain recent mixed evidence on the pandemic’s impact on students’ mental health and well-being. (JEL H75, I12, I21, I28, I31)

Published: August 2022

Objectives

To evaluate the influence of intravenous contrast agent on the diagnostic ability for osteoporosis using CT attenuation measurement in patients with liver cirrhosis.

Methods

This retrospective study was approved by our institutional review board and informed consent was waived. 208 patients with liver cirrhosis (mean age, 61.25 years ± 9.43 [standard deviation]; range, 30–82 years) who underwent both unenhanced and two contrast-enhanced (arterial and venous phase) abdominal dual-energy CT examinations from January 1 to September 1, 2020, were recruited. CT attenuation values were measured in the medullary compartment of vertebral body (L1–L3) and bone mass was determined by the hydroxyapatite concentration obtained in dual-energy spectral CT and used as the reference standard. Receiver operating characteristic (ROC) curves were used to evaluate the diagnostic ability of using CT attenuation number in unenhanced, arterial, and venous phases.

Results

Area under ROC curve using unenhanced CT attenuation was different from using arterial CT attenuation (p = 0.038) and venous CT attenuation (p = 0.048) to diagnosing osteoporosis. However, there was no significant difference between unenhanced CT attenuation and arterial CT attenuation (p = 0.773) and between unenhanced CT attenuation and venous CT attenuation (p = 0.746) to distinguish low bone mass (osteoporosis or osteopenia).

Conclusions

The diagnostic ability for osteoporosis using CT attenuation measurement in contrast-enhanced scans is decreased due to intravenous contrast contamination, however, which had no influence on the diagnostic ability of CT attenuation for low bone mass (osteoporosis or osteopenia).

Advances in knowledge

The diagnostic ability of using enhanced CT attenuation values for osteoporosis decreased compared to unenhanced CT attenuation values.

Published: August 2022

Eccrine porocarcinoma is a rare type of skin neoplasm. It represents less than 0.01% of all epithelial cutaneous tumors. Early diagnosis is the only way to minimize the mortality rate, given its aggressive nature and the high rate of local recurrence and metastasis. Clinical diagnosis is challenging and the confirmation is histological. Few studies have been published about the radiological features of eccrine porocarcinoma. We report a case of a localized eccrine porocarcinoma along with ultrasound, MRI features, and a review of the literature to highlight the role of imaging in the diagnosis and treatment plan.
Testicular adrenal rest tumours in an adult patient with congenital adrenal hyperplasia
Authors: Forster Danielle Andrea , Marzouk Sherief , Chakraborti Indrani , Berney Daniel , Wolfe Konrad , Liyanage Sidath H
Published: August 2022

Testicular adrenal rest tumours (TART) are found in patients with congenital adrenal hyperplasia (CAH) with the severity of testicular infiltration linearly related to the degree of enzymatic defect and subsequent compliance with treatment. We report a highly unusual case of TART in an adult patient with CAH caused by 21-hydroxylase deficiency who had not engaged with health services over a 3-year period. Typical imaging features of TART include bilateral well-defined lesions adjacent to the rete testes. However, in this rare case, the follow-up imaging found that the entirety of the testicular parenchyma had been replaced with TART and the patient had gone on to develop an adrenal nodule. As these testicular tumours are commonly misdiagnosed as primary germ tumours and tend respond well to treatment with circadian or reverse glucocorticoids, it is essential for the radiologist to be aware of both the common and more unusual imaging features appearances of TART in patients with CAH in order to facilitate early diagnosis and thus timely initiation of treatment.

Authors: Griffin Anne , Cerenay Sarier , Ryan Lorna , Conneely Mairéad , Bowers Sheila , Dore Liz , Galvin Rose
Published: August 2022

Introduction: Nutrition status among older adults is an important factor in health and clinical outcomes but malnutrition goes unrecognised in routine health care.  Older adults often present to emergency departments (ED) and are subsequently discharged without hospital admission.  Discharge is a transitionary time of care when nutritional vulnerability could be mitigated with the instigation of targeted nutrition care pathways. This protocol outlines a scoping review to identify the level of nutrition care provided to older adults attending emergency departments.

Methods: This scoping review will be conducted using the framework proposed by the Joanna Briggs Institute. The Preferred Reporting Items for Systematic Reviews and Meta-analysis extension for scoping reviews (PRISMA-ScR) will be used to guide the reporting. Two researchers will search electronic databases (Medline, CINAHL Complete, EMBASE, Cochrane Library and Scopus), grey literature sources (DART-Europe E-theses portal, Open Grey, and Trip Medical database) and website searches (Google, Google Scholar, Pubmed, NICE and LENUS) to identify appropriate data for inclusion within the last 10 years. Key information will be categorised and classified to generate a table charting the level of nutrition and dietetic care initiated for older adults in the ED according to the Nutrition Care Process Model. A narrative synthesis will be conducted.

Conclusions: This scoping review will be used to inform a foundational concept of nutrition care in an ED setting and allow the future examination of nutrition care pathways, practice, policy, and research within models of integrated care for older persons.

Effect of glucagon-like peptide-1 (GLP-1) agonists on the example of semaglutide on the cardiovascular system and their role in the treatment of obesity.
Authors: Pondel Kamil , Kawałko Kinga , Bielewicz Krzysztof , Chmura Anna , Karaś Anna
Published: August 2022

Obesity nowadays affects an increasing number of people. We can talk about it when the patient's BMI is ≥ 30.0 kg/m² (BMI 25.0-29.9 kg/m² - overweight). While obesity in itself may not be a problem for people suffering from it, its complications can be global and sometimes pose a serious threat to health or even life. Its main complications in the cardiovascular system include: hypercholesterolaemia, arterial hypertension, left ventricular hypertrophy, early atherosclerotic changes, heart and cerebral infarction. Treatment of obesity is based mainly on changing the patient's lifestyle - diet and physical activity, which can sometimes be problematic and difficult to apply.

However, there is a new group of hypoglycaemic drugs - glucagon-like peptide-1 (GLP-1) agonists, which can make obesity treatment easier. These drugs use the incretin effect in the body to increase insulin secretion in response to a meal containing carbohydrates and prevent postprandial hyperglycemia. In this article, we will analyze the latest studies on the effects of GLP-1 receptor agonists, using semaglutide as an example, on the cardiovascular system and on weight loss in patients.
The impact of L-Arginine supplementation on disorders associated with obesity
Authors: Żyga Justyna
Published: August 2022

Introduction: L-Arginine (2-amino-5-guanidinovaleric acid) is a conditionally essential amino acid and a natural constituent of dietary proteins, serving as a precursor for the synthesis not only of proteins, urea, polyamines, proline, glutamate and creatine. This amino acid is a substrate for nitric oxide production, an endogenous messenger molecule involved in a variety of endothelium mediated physiological effects in the vascular system. 

State of knowledge: The evidence suggests supplementation of L-Arginine may have a positive impact in conditions associated with obesity - type 2 diabetes, atherosclerosis or hypercholesterolaemia. The L-Arginine intake improves insulin sensitivity and may improve lipid profile reducing triglyceride serum levels. As a precursor for nitric oxide synthesis, a molecule involved in a variety of physiological effects in the vascular system, L-Arginine can have a positive impact on the cardiovascular system.

Conclusions: The evidence suggests that the L-Arginine may improve lipid profile reducing triglyceride serum levels. L-Arginine could be used as a strategy to improve endothelial function in the selected group of patients. Careful studies are necessary to assess its safety profile, determine under which conditions L-Arginine supplementation is appropriate and when it is undesirable. Attention should be focused to markers of oxidative stress and blood pressure stability.
Oedema prevention in physiotherapy practice using Kinesiology Taping
Authors: Wicha Weronika
Published: August 2022

Prophylaxis against edema involves the removal of excess lymph fluid from a specific area of the body. The presence of lymph accumulation, is a sign of abnormalities in the functioning of the lymphatic system, which has lost the ability to properly transport lymph.
Swelling otherwise known as lymphedema is among the chronic diseases that adversely affect the functioning of human systems.
Lymphedema is one of the most common disorders of the lymphatic system. Its correct function is to drain lymph into the lymphatic vessels, and from there it travels to the lymph nodes. Its malfunction is the failure to drain the lymph into the lymphatic vessels or the lymph nodes. As a result of the abnormal lymph circulation, swelling usually occurs in the lower and upper extremities. The swelling at first appears to be painless, but over time it becomes hard thus reducing the functional capacity of the limbs. Over time, the skin and subcutaneous tissue can become infected, which can affect the formation of a cancer such as lymphosarcoma.
Increasingly, so-called dynamic Plastering is being used to assist and alleviate lymphedema. Kinesiology Taping (KT) otherwise known as dynamic patching enables the reduction of swelling by elevating the skin, thus increasing the surface area between the skin and fascia. This results in body fluids having more room to flow freely to the lymph nodes, and this reduces our swelling and lymph accumulation in the extremities.[2]
The purpose of this paper is to show the use of  Kinesiology Taping to reduce lymphedema. The paper is based on a review of articles in reputable journals from past years.

Mean Field Contest with Singularity
Authors: Nutz Marcel , Zhang Yuchong
Published: August 2022

We formulate a mean field game where each player stops a privately observed Brownian motion with absorption. Players are ranked according to their level of stopping and rewarded as a function of their relative rank. There is a unique mean field equilibrium, and it is shown to be the limit of associated n-player games. Conversely, the mean field strategy induces n-player ε-Nash equilibria for any continuous reward function—but not for discontinuous ones. In a second part, we study the problem of a principal who can choose how to distribute a reward budget over the ranks and aims to maximize the performance of the median player. The optimal reward design (contract) is found in closed form, complementing the merely partial results available in the n-player case. We then analyze the quality of the mean field design when used as a proxy for the optimizer in the n-player game. Surprisingly, the quality deteriorates dramatically as n grows. We explain this with an asymptotic singularity in the induced n-player equilibrium distributions.

UMA EXPERIÊNCIA FORMATIVA NO CONTEXTO UNIVERSITÁRIO: o projeto Arte e Diferença
Authors: Farid Rahme Monica Maria , Viana Anamaria Fernandes
Published: August 2022

Este artigo apresenta o Projeto de extensão Arte e Diferença, desenvolvido na Universidade Federal de Minas Gerais desde 2017.  O projeto consistia, incialmente, na realização de oficinas artísticas com jovens e adultos com e sem deficiência, processo que sofreu alterações nos anos de 2020 e 2021 em decorrência da pandemia. O texto discorre sobre cinco princípios norteadores do projeto: acessibilidade, ludicidade, autoralidade, articulação entre o singular e o coletivo, curiosidade pelo outro, evidenciando o entrelaçamento desses princípios ao percurso de trabalho proposto . O texto focaliza elementos relacionados à proposta metodológica do projeto e aos seus efeitos para o percurso formativo das estudantes, tendo em vista a constatação de que a temática da deficiência ainda ocupa uma posição secundária na formação universitária.  Os conceitos de hospitalidade e plasticidade são retomados para refletir sobre o lugar ocupado pelo outro, sobretudo quando a experiência do outro se coloca na dimensão do estrangeiro, facilmente enquadrado em rótulos  e saberes previamente definidos. Ao longo da escrita do artigo, busca-se indicar a potencialidade da extensão, articulada às atividades de ensino e pesquisa, como vertente que favorece um engajamento da universidade com as questões e desafios vivenciados pelos sujeitos na atualidade.
UMA REFLEXÃO SOBRE A ATUAÇÃO DE UMA COLETIVA DE MULHERES NEGRAS NA PESPECTIVA DA DECOLONIALIDADE
Authors: Eiterer Carmem Lucia , Da Silva Tatiana Neves
Published: August 2022

A luta das mulheres negras por inclusão e justiça social, tem sido historicamente marcada por desafios, tensões e avanços. A partir da década de 1970, vemos a efervescência das organizações de mulheres negras no Brasil, na resistência às opressões, desigualdades sociais, e pela visibilidade de suas narrativas nos diversos espaços sociais. Diante do silenciamento e invisibilidade impostos pela branquitude: hegemônica, eurocêntrica, racista, colonial, as mulheres negras refletem juntas, sobre os enfrentamentos a esse sistema, à colonialidade do poder, saber e ser (QUIJANO,2005). Nesse sentido, o objetivo deste trabalho é refletir a respeito das estratégias de superação das desigualdades e de busca por justiça social, engendradas por uma Coletiva de Mulheres Negras, atuante em um Aglomerado de Belo Horizonte, capital do estado de Minas Gerais. Essa coletiva afeta mulheres, em sua maioria negras, da periferia em que está sediada. Esses afetos (ações) são pensados no sentido do cuidado e autocuidado, da potencialização da educação antirracista, da tentativa de diminuição da insegurança alimentar, ainda mais presente no cenário da Pandemia de COVID-19. Nessa direção, verifica-se que essa organização de mulheres alcança e acolhe um território, que fica à margem das ações do poder público. Dessa forma, a única atuação ostensiva do Estado é observada na força policial, que em diversas ocasiões, mostra-se de forma violenta na periferia. Para tecer as reflexões pretendidas nesse artigo, estabelece-se diálogo com o feminismo negro decolonial e com autores que nos auxiliam a compreender a dimensão interseccional de raça, gênero e classe social.

Conceitos como educação pelo dendezeiro, pesquisador cambono, cruzos, encruzilhada, cablocamento são cruzados com os arcabouços teóricos e metológicos até aqui já apresentados, para enxergamos os contragolpes construídos por professoras e professores de História contra o carrego colonial dentro desse campo.
TRAVESSIAS FILOSÓFICAS, TESSITURAS AMEFRICANAS: O CURRÍCULO DE FILOSOFIA AO RÉS-DO-CHÃO
Authors: Reis Diego Dos Santos , Carreiro Gabriela Da Nóbrega
Published: August 2022

O ensaio tem por objetivo difundir o debate em torno da descolonização do ensino de filosofia e seu currículo, tendo como eixo a crítica ao exclusivismo de perspectivas filosóficas brancas, androcentradas, eurocêntricas e universalistas, hegemônicas nos espaços institucionais de formação e nas práticas pedagógicas. Pontua-se que a manutenção de uma matriz particular de conhecimento como a única válida e verdadeira, que passa a conferir valor a acervos, currículos e repertórios ensinados nas instituições, atravessa estruturalmente os itinerários formativos propostos pelas instituições educativas nacionais. Ressalta-se, nesse contexto, a importância das legislações antirracistas, como a Lei 10.639/03, e de práticas contracoloniais que interroguem não apenas os modelos filosóficos canônicos, mas também os processos de desumanização daqueles/as que foram tornadas/os subalternas/os pela lógica colonial, e que, desde seu chão, produzem conhecimentos filosóficos que desafiam o sistema-mundo colonial/capitalista/racista/patriarcal e seus arquivos. Trata-se, por fim, de indagar políticas curriculares, práticas pedagógicas e epistemologias, para enfrentar os lastros da colonialidade no ensino de filosofia.

CENGİZ AYTMATOV’UN DENİZ KIYISINDA KOŞAN ALA KÖPEK ROMANINDA MEKÂNIN RUHU VE “KENDİLEME” KAVRAMI
Authors: ASLAN COBUTOĞLU Serap
Published: August 2022

Sadece Kırgız edebiyatının değil, tüm Türk dünyası edebiyatlarının mümtaz yazarlarından biri olan Cengiz Aytmatov’un birçok eserinde mekân ile insan arasında kurduğu özel etkileşimlerin varlığı bilinmektedir. Eserlerinde insan psikolojisinde ufuk açıcı mahiyette bir kavrayış geliştiren yazarın temel dayanaklarından birinin tutkuyla bağlı olduğu coğrafya, doğa, mekân ve yer bilgisi olduğunu söylemek mümkündür. Bu bakımdan hikâye ve romanlarında çevre problemleri, doğal dengenin bozulmasına koşut insan özünün de bozulması gibi konuları özel bir hassasiyetle ele aldığı görülen yazarın eserlerindeki mekânsal unsurlar “insan”a ulaşmada ve “insan”ı anlamada temel belirleyen olarak karşımıza çıkmaktadır. Aytmatov’un eserleri üzerinde yapılacak ayrıntılı mekân çalışmalarının ise yazarı ve eserlerinde yarattığı karakterleri anlama noktasında farkındalık yaratacağı muhakkaktır. Bu minvalde bu çalışma, Cengiz Aytmatov’un Deniz Kıyısında Koşan Ala Köpek romanında ele alınan mekân ve kimlik konusuna odaklanmaktadır. Eserde yerin karakteri görsel ve mekânsal özelliklerin ötesinde boyutlara sahiptir. Bir arayış ve kurtuluş macerasının anlatıldığı romanda tabiata ait birçok uzamsal birimin kimliksel bir değer üzerinden simgeleştirildiği ve kültürel yönüyle ruhsal bir değer olarak romanda yer aldığı görülür. Eserde mekânı yüceltmeye ve mitselleştirmeye dönük her çaba, yerin kendine özgü bir kimlik kazanması ve sakinlerinin onu sahiplenmesi sonuçlanmıştır. Bu durum, insanın yaşadığı mekânı “kendileme/kendinin kılma” olgusu ile paralellik göstermektedir. Romanda çoğunlukla çocuk karakter Kirisk’in gözünden ve bakış açısından anlatılan mekânsal birimler “kendileme” kavramı etrafında yer kimliği üzerinden şekillenirler. Bu çerçevede bu makalede, Deniz Kıyısında Koşan Ala Köpek romanından hareketle mekânın kimliksel değeri yer kimliği olgusu üzerinden okunmuş ve “kendileme/kendinin kılma” kavramı etrafında yer kimliğinden kimlik yerine geçiş sürecine değinilmiştir
The Impact of Obstructive Sleep Apnea on the Development of Refractory Nasal Symptoms After Adenoidectomy
Authors: Patel Aneesh A. , Brook Christopher D. , Levi Jessica R.
Published: August 2022

Objectives: Chronic rhinitis may contribute to a persistently decreased quality of life in patients undergoing surgical treatment for obstructive sleep apnea (OSA). This study aimed to characterize the role of OSA in pediatric patients with refractory chronic rhinitis after adenoidectomy.Methods: We reviewed the charts of patients <18 years of age with a history of OSA who underwent adenoidectomy at an academic medical center from October 2012 to December 2018 and that were seen in the clinic for follow-up. They were identified through the Current Procedural Terminology (CPT) codes 42830 and 42831 with the exclusion of CPT 42820 for tonsillectomy and adenoidectomy. Patients with a prior diagnosis of OSA who had refractory symptoms were compared with those who had symptoms resolution using chi-square analysis and t-tests.Results: Thirty-six (35.0%) patients with refractory symptoms following adenoidectomy and 52 (37.4%) patients without refractory symptoms had a history of OSA before surgery (p=0.80). In patients with refractory symptoms, the average age (3.8 years) and male sex (n=24, 66.7%) did not differ significantly from the age (4.42 years) and male sex (n=36, 69.2%) percentages of patients without refractory symptoms. The mean apnea/hypopnea-index (AHI) (p=0.91), completion of the sleep study (p=0.41), history of snoring (p=0.92), and tonsil size (p=0.42) did not differ significantly between the groups. However, patients with refractory symptoms had a significantly higher mean body mass index (BMI) (19.58) than those who did not (17.77, p=0.04) and completed a higher number of allergy evaluations (p=0.02).Conclusions: While the history and severity of OSA did not differ significantly in patients with refractory nasal symptoms after adenoidectomy, these patients had a significantly higher BMI and completion of allergy evaluation.

Authors: Pieri Marco De , Manconi Mauro , Miano Silvia
Published: August 2022

The mandibular advancement device (MAD) is a therapeutic option for obstructive sleep apnea syndrome (OSAS); however, for severe cases, it has a lower efficacy compared to continuous positive airway pressure (CPAP). This report aimed to present the efficacy of MAD in a patient with severe OSAS who refused CPAP. Video-polysomnography and polygraphy were performed before and after treatment, respectively. Three months after fitting and titrating the MAD, the apnea–hypopnea index was reduced from 56.2 events/h to 1.3 events/h and the minimum oxyhemoglobin saturation increased from 80% to 91%. Snoring time reduced from 75.2% to 0.2%. Our patient presented with low body fat, retrognathia, pharyngeal obstruction mainly along the anteroposterior axis and at the base of the tongue, and the ability to make wide protrusive movements with the jaw. In our opinion, these features could constitute a phenotype that may predict a positive response to MAD treatment even in severe cases of OSAS.

Obesity hypoventilation syndrome (OHS) is defined as the combination of daytime hypercapnia (awake PaCO2 ≥45 mm Hg) and obesity (body mass index ≥30 kg/m2). Untreated OHS is associated with comorbidities, including cardiovascular diseases, heart failure, pulmonary hypertension, and metabolic syndrome. Continuous positive airway pressure (PAP) therapy with non-invasive ventilation is the gold standard for treating OHS. PAP therapy is highly effective; however, some adverse effects can affect long-term compliance. Air leakage through the mouth or around a mask is a common adverse effect of PAP therapy. Air leakage through the nasolacrimal duct or due to unsealed circuits has also been reported as a complication of PAP therapy; however, it is relatively rare. Considering the negative association between the level of air leakage and adherence to PAP therapy, clarifying the cause of air leakage during PAP therapy and minimizing it are key to successful outcomes. We report a case of air leakage through the nasolacrimal duct that was improved by inserting a gel foam patch inside the lacrimal sac of a patient with OHS with a history of reconstructive surgery for nasolacrimal duct obstruction.
Ultra-narrow linewidth transmission filters based on the cladding mode assisted Fabry–Perot effect in a planar waveguide
Authors: Koley Avijit , Tripathi Saurabh Mani
Published: August 2022

We propose and analyze a counterpropagating cladding mode assisted tunable frequency Fabry–Perot interferometer formed by a Bragg grating (BG) cavity in a liquid crystal coated planar optical waveguide. A full vector modal analysis has been used to obtain the transmission spectra of the individual Bragg reflectors, and the cavity effects have been incorporated by employing a suitable phase matrix. We show that the cavity resonances that appear from two fiber BGs forming a resonator can be efficiently explained by incorporating appropriate phase shifts in one BG grating period. We further show that utilizing the cladding mode evanescent field, a liquid crystal overlay can be used to tune the cavity resonance over the entire free-spectral range of the cavity transmission spectra. Our study should find application in designing highly tunable integrated optical Fabry–Perot interferometers.

The spatial resolution of the direct imaging system depends on the wavelength and the numerical aperture. In the terahertz (THz) waveband, the wavelength is relatively large, and the higher numerical aperture of the imaging system usually promises the possibility of achieving higher spatial resolution. Solid immersion technique is an effective method to expand the numerical aperture. We design and fabricate a hemisphere lens with high-resistance silicon to achieve the effect of solid immersion, and obtain full-field, high-resolution focal-plane imaging. The characteristics of the direct refraction imaging and the secondary reflection imaging are analyzed by ray-tracing calculations. And the field curvature of the equivalent object plane and the spot diagram on the vertical image plane of the lens are quantifiably evaluated. It is shown that the secondary reflection imaging can effectively reduce the geometric distortion and achieve more ideal imaging quality. The method of blocking different regions before and after the solid immersion lens is proposed to obtain a clear magnified image of a two-dimensional grating with the period of 300 µm. This method provides a powerful tool for THz full-field microscopic imaging.

The structure of silica single-mode fiber (SMF) must be modified in order to develop optical fiber-based biosensors. To reduce the diameter of the optical fiber, a low-cost chemical etching method is very popular. The proposed chemical etching method is a simple, rapid, and cost-effective technique for removing the silica cladding up to a desired diameter. In the laboratory, hydrofluoric acid (HF acid, 40% concentration) is used for etching. A variation on etching is also proposed and tested with 40% HF as well as with magnetic stirring at the different speeds. The etching experiments are also carried out at different temperatures. The etching results of silica fiber are presented through a step-by-step procedure using a rapid and resource-efficient method for the fabrication of optical fiber-based biosensors. The etched diameter characterization is done using a calibrated compound microscope. The sensing experiment with unetched and etched optical fiber is also performed for the detection of different concentrations of glucose biomolecules.

Optical coherence tomography (OCT) is a high-speed non-invasive cross-sectional imaging technique. Although its imaging speed is high, three-dimensional high-spatial-sampling-density imaging of in vivo tissues with a wide field-of-view (FOV) is challenging. We employed convolved Lissajous and slow circular scanning patterns to extend the FOV of retinal OCT imaging with a 1-µm, 100-kHz-sweep-rate swept-source OCT prototype system. Displacements of sampling points due to eye movements are corrected by post-processing based on a Lissajous scan. Wide FOV three-dimensional retinal imaging with high sampling density and motion correction is achieved. Three-dimensional structures obtained using repeated imaging sessions of a healthy volunteer and two patients showed good agreement. The demonstrated technique will extend the FOV of simple point-scanning OCT, such as commercial ophthalmic OCT devices, without sacrificing sampling density.

We present a holographic tomography technique in which the projections are acquired using both wavelength and illumination scanning in the near-infrared region. We show how to process the acquired data to obtain correct values of three-dimensional refractive index distributions in both single-wavelength and multi-wavelength data acquisition schemes and how to properly account for the dispersion of the sample. We perform numerical and experimental comparisons of different illumination scenarios to determine the most efficient measurement protocol. We show that the multi-wavelength protocol is advantageous in terms of signal-to-noise ratio and contrast-to-noise ratio over single-wavelength protocols, even for the same number of projections used for reconstructions. Finally, we show that this approach is suitable for providing high-quality refractive index distributions of relatively thick colon cancer samples.
ℏω versus ℏk: dispersion and energy constraints on time-varying photonic materials and time crystals [Invited]

Photonic time-varying systems have attracted significant attention owing to their rich physics and potential opportunities for new and enhanced functionalities. In this context, the duality of space and time in wave physics has been particularly fruitful to uncover interesting physical effects in the temporal domain, such as reflection/refraction at temporal interfaces and momentum-bandgaps in time crystals. However, the characteristics of the temporal/frequency dimension, particularly its relation to causality and energy conservation (

ℏ
ω

is energy, whereas

ℏ
k

is momentum), create challenges and constraints that are unique to time-varying systems and are not present in their spatially varying counterparts. Here, we overview two key physical aspects of time-varying photonics that have only received marginal attention so far, namely temporal dispersion and external power requirements, and explore their implications. We discuss how temporal dispersion, an inherent property of any physical causal material, makes the fields evolve continuously at sharp temporal interfaces and may limit the strength of fast temporal modulations and of various resulting effects. Furthermore, we show that changing the refractive index in time always involves large amounts of energy. We derive power requirements to observe a time-crystal response in one of the most popular material platforms in time-varying photonics, i.e., transparent conducting oxides, and we argue that these effects are almost always obscured by less exotic nonlinear phenomena. These observations and findings shed light on the physics and constraints of time-varying photonics, and may guide the design and implementation of future time-modulated photonic systems.

Immunization is one of the most effective public health interventions, saving millions of lives every year. Ethiopia has seen gradual improvements in immunization coverage and access to child health care services; however, inequalities in child mortality across wealth quintiles and regions remain persistent. We model the relative distributional incidence and mortality of four vaccine-preventable diseases (VPDs) (rotavirus diarrhea, human papillomavirus, measles, and pneumonia) by wealth quintile and geographic region in Ethiopia. Our approach significantly extends an earlier methodology, which utilizes the population attributable fraction and differences in the prevalence of risk and prognostic factors by population subgroup to estimate the relative distribution of VPD incidence and mortality. We use a linear system of equations to estimate the joint distribution of risk and prognostic factors in population subgroups, treating each possible combination of risk or prognostic factors as computationally distinct, thereby allowing us to account for individuals with multiple risk factors. Across all modeling scenarios, our analysis found that the poor and those living in rural and primarily pastoralist or agrarian regions have a greater risk than the rich and those living in urban regions of becoming infected with or dying from a VPD. While in absolute terms all population subgroups benefit from health interventions (e.g., vaccination and treatment), current unequal levels and pro-rich gradients of vaccination and treatment-seeking patterns should be redressed so to significantly improve health equity across wealth quintiles and geographic regions in Ethiopia.
