Authors: Tarigan Liberti , Sidauruk Juliana Lasniar
Published: September 2022

The clavicle is an S-shaped bone that articulates laterally with the acromioma process of the scapula, medially with the manubrium of the clavicular notch to form the clavicular joint. An avulsion fracture is a disconnection of the clavicle bone caused by direct and indirect trauma in the position of the arm being cut off or pulled out (outstretched hand) because the trauma continues from the wrist to the clavicle. Radiography is an appropriate method to show abnormalities in the os calvicula. The aim is to show the anatomy of the clavicle bone and its abnormalities. This examination uses the Antero-Posterior projection. The X-ray aircraft used is GE with a capacity of 500 mA. The tape used is 30 cm x 40 cm. Processing film used is Computed Radiography.

Published: September 2022

The increased awareness of the value of physical activity by introducing sports and games in the Physical Education curriculum of special education (SPED) schools in the Philippines has been both a trend and a challenge in program planning, implementation, assessment, and professional background of teachers. To evaluate the benefits of learners’ participation in physical activity, this study, therefore, measured and evaluated the health-related physical fitness status of learners in an educational institution for the visually impaired in the Philippines. The health-related physical fitness levels of blind or braille user learners (N = 12) were measured utilizing the following standardized tests: body mass index (BMI); modified sit and reach and zipper tests (flexibility); vertical jump test (power); four-level sit-ups (core strength); and 3-minute step test (cardiorespiratory endurance). Overall results revealed that the participants’ health-related physical fitness levels were below normative standards for fitness. Interviews among the special education teachers of the institution also revealed that their minimal training on fitness testing and physical activity programming, including the scarcity of materials and equipment, emerged as common problems encountered by them as far as fitness is concerned. Given the proper training on the conduct and monitoring of physical fitness tests and the facilitation of physical activity-related programs, special education teachers will be able to address the children’s needs in physical activity, fitness, and leisure programs. The results of the study will serve as inputs toward the development of a comprehensive fitness and leisure program, especially in SPED schools.

Cultivating a Culture of Innovation: The Experience of Al Salam Private School in Dubai, United Arab Emirates
Authors: Santos Mark Rey
Published: September 2022

Innovation, being one of the initiatives of the UAE, has been mandated to be promoted and cultivated in all government sectors including education. In response to the mandate, schools incorporated innovation into their system and operation. Al Salam Private School, in its existence for more than 30 years, has made a lot of innovative steps to address the call and demands of the time. The culture of innovation in Al Salam Private School may already be existing, but in order to know how to move forward, an assessment was made to determine the perception of the staff. The Six Building Blocks of an Innovative Culture instrument of Rao and Weintraub (2013) was modified to suit and fit the need of the survey. The survey revealed that overall, the culture of innovation in Al Salam Private School is to a great extent. Specifically, the culture of innovation in terms of values, behaviors, climate, and processes are to a great extent while resources and success are to a moderate extent. The focus areas derived from the three least rated elements in the survey are: having good incentive systems which recognize and reward innovation, rewarding people for participating in potentially risky opportunities, irrespective of the outcome, and having inspiring physical spaces for staff to collaborate, be creative and engage in innovative practice. Three emerging themes were extracted from the interview with the key informants, and these are incentives and recognition, risk-taking activities, and collaborative and inspiring space. These themes were consistent with the focus areas derived from the survey. From the integration of the quantitative and qualitative analysis, an eidetic model of the culture of innovation was developed. The three pillars of the model served as the key priority areas in the crafting of the Innovation Plan.

Published: September 2022

This research highlights the aspects of resiliency among business establishments in the Visayas regions that were directly affected by super typhoon Yolanda in 2013. This study employs a descriptive method to characterize resiliency factors among various businesses. A survey questionnaire was utilized to gather relevant data from the 106 business proprietors and managers. Multivariate analysis via exploratory factor analysis (EFA) was used to determine the underlying factors. In the context of the post-disaster recovery of businesses in the Visayas regions, the exploratory analysis yielded five dimensions. Based on the finding, five causal factors are significant in developing a post-disaster resiliency and recovery framework among various business types. Any business is considered resilient against any form of disaster if it has complete control of its institutional affairs and plans ahead guided by its philosophy. Futuristic planning is also necessary as it imbibes in its operational philosophy the value of foresight. Besides, every business needs to strengthen its linkages outside its operations. Hence, a resilient business considers the value of information exchange and dissemination. Thus, a business is said to be sustainable if it maintains a sound and working framework to improve an adaptive capacity for any calamity or disaster.

Published: September 2022

Along with Indonesia, the COVID-19 outbreak has expanded across the globe. All facets of community life are affected by this disruption, including the educational system, which shifts from face-to-face instruction to online distance learning. To break the link of the COVID-19 outbreak's spread, the West Sumatra PGRI STKIP campus has made changes to the educational system. Without having to travel to a campus, students can learn online from the comfort of their own homes. However, this causes students to have issues with internet networks, quota availability, and understanding in the classroom. The goal of this study was to describe the methods used by students to deal with challenges presented by online learning in the COVID-19 program. The idea put forth between COVID-19 outbreaks. Constructivism theory was the one that was employed. Additionally, this study takes a qualitative descriptive technique to offer information about students' online learning strategies. Twenty students and five professors served as the study's informants. using Matthew Milles and Huberman's interactive model to analyze the data after gathering it through interviews and documentation. The study's findings show that students always provide a quota before classes begin, opt for a place where they can easily access the internet, question friends about concepts they don't understand, read articles and tutorials on YouTube, and always have memory available.

Published: September 2022

Background:

Moyamoya disease is a chronic, progressive cerebrovascular disease involving occlusion or stenosis of the terminal portion of the internal carotid artery. We conducted an updated systematic review and meta-analysis to investigate clinical and angiographic outcomes comparing direct, combined, and indirect bypass for the treatment of moyamoya disease in adults.

Methods:

Two independent authors performed Preferred Reporting Items for Systematic reviews and Meta-Analyses guided literature searches in December 2021 to identify articles reporting clinical/angiographic outcomes in adult moyamoya disease patients undergoing bypass. Primary end points used were ischemic and hemorrhagic strokes, clinical outcomes, and angiographic revascularization. Study quality was evaluated with Newcastle-Ottawa and the Oxford Center for Evidence-Based Medicine scales.

Results:

Four thousand four hundred fifty seven articles were identified in the initial search; 143 articles were analyzed. There were 3827 direct, 3826 indirect, and 3801 combined bypasses. Average length of follow-up was 3.59±2.93 years. Pooled analysis significantly favored direct (odds ratio [OR], 0.62 [0.48–0.79];
P
<0.0001; OR, 0.44 [0.32–0.59];
P

P
<0.0001; OR, 0.28 [0.2–0.41];
P
<0.0001; OR, 0.41 [0.3–0.56];
P
<0.0001; OR, 3.1 [2.8–4.3];
P

P
<0.0001) and direct (OR, 4.12 [2.34–7.25];
P
<0.0001) for early intracerebral hemorrhage. The meta-analysis significantly favored direct (OR, 0.37 [0.23–0.60];
P
<0.001; OR, 0.49 [0.31–0.77];
P
=0.002) and combined (OR, 0.23 [0.12–0.43];
P
<0.00001; OR, 0.30 [0.18–0.49];
P
<0.00001) bypass over indirect bypass for late stroke and late hemorrhage, respectively. Combined bypass was favored over indirect bypass for favorable outcomes (OR, 2.06 [1.18–3.58];
P
=0.01).

Conclusions:

Based on combined meta-analysis (43 articles) and pooled analysis (143 articles), the existing literature indicates that combined and direct bypasses have significant benefits for patients suffering from late stroke and hemorrhage versus indirect bypass. Combined bypass was favored over indirect bypass for favorable outcomes. This is a strong recommendation based on low-quality evidence when utilizing the Grades of Recommendation, Assessment, Development, and Evaluation system. These findings have important implications for bypass strategy selection.
When the Intellectuals of ‘Ḥarrān Contributed to Falsafa’
Authors: Awad Najib George
Published: September 2022

In this essay, I attend to an under-analyzed topic in the history of Kalām and Falsafa studies, the contribution of Theodore Abū Qurrah, a Melkite-Chalcedonian Arab-Speaking mutakallim of the early Abbasid era, to the Greek-Arabic translation movement and to Falsafa and Kalām, via the translations he made or through the philosophical ideas that underpin his own Kalām discourses. I will pay specific attention to a possible transmission of the Neoplatonic-Aristotelian heritage of Proclus through Abū Qurrah’s use of Proclean ideas in his own Christian Kalām. I will argue that some of Abū Qurrah’s literary output is expressive of his endeavor to develop an independent reading of Proclus and offer a fresh implementation of Proclean legacy in a Kalām-form that exceeds the boundaries of the traditional reading of Proclus. I will begin with insights on Kalām and the translation movement. I will move then to discuss the place of Ḥarrān (the city which Abū Qurrah belonged to and was the Melkite bishop in) on the map of the transmission of Greek sciences to Arabic, before paying attention to the role of the Bishop of Ḥarrān in this transmission activity. After setting the contextual framework, I will focus in the ensuing sections on some traces of Proclus’s legacy in Theodore Abū Qurrah’s extant texts.

This new genus is diagnosed by the occipital carina extending to the lower half of the head, the pronotum lacking an epomia, the pterostigma short, the petiole open but very short, the ovipositor wide and bent throughout, with its apex widely rounded. Diagnostic characters of Disogmini are revised.
Transitional morphology and Afrotropical affinity of a bythinoplectine rove beetle from the early Eocene of India (Coleoptera: Staphylinidae: Pselaphinae)
Authors: PARKER JOSEPH
Published: September 2022

Recently discovered Ypresian-age amber from Cambay, India, reveals an ancient arthropod assemblage on the Indian subcontinent during its collision with Asia. Despite the tectonic history of India, limited connections have been found between the Cambay palaeofauna and present-day Madagascan and mainland African faunas. Here, I describe a new fossil pselaphine rove beetle (Staphylinidae: Pselaphinae) recovered from the Cambay deposit that shows closest apparent phylogenetic affinity to modern Afrotropical genera. Yprezethinus grimaldii gen. et sp. nov. is placed in Bythinoplectini, subtribe Bythinoplectina. Based on antennal and maxillary palp morphology, Yprezethinus is a putative transitional stem lineage of the Zethinus-group of genera—an extant clade distributed across equatorial African rainforests. Although Yprezethinus shares with this clade the derived feature of ovoid antennal clubs formed by tight appression of the apical two segments, it differs from its putative extant relatives in its possession of the plesiomorphic complement of 11 antennomeres, without any fusions of segments. The fossil taxon signifies a biotic link between early Eocene India and continental Africa, and marks the Cenozoic emergence of a tropical leaf litter arthropod fauna approaching that of contemporary, ant-dominated rainforests.

Authors: PEÑALVER ENRIQUE , ARILLO ANTONIO , NEL ANDRÉ
Published: September 2022

A new species, Eltxo grimaldii sp. nov., is described from Spanish Lower Cretaceous (middle Albian) amber from El Soplao, based on a single female. The new species is compared with the other only known species of the genus, Eltxo cretaceus Arillo & Nel, 2000, based on a single male specimen also found in Spanish amber, but slightly younger (Peñacerrada I amber; upper Albian). The holotype of E. cretaceus is reviewed and its description corrected and expanded, providing the first micrographs of its anatomical features. The holotype of the new fossil species is the only female specimen known of the cecidomyiid tribe Amediini Jaschhof, 2021, a tribe recently described after changes of taxonomic attribution of the genus Eltxo during the last 20 years.

Research Progress on Analytical and Numerical Prediction of Curing Deformation in Thermoset for Large Composite Parts
Authors: Yang Xue-Yong , Xiao Jun
Published: September 2022

Solidification deformation will produce certain drawbacks, so that a composite material part may not meet the requirements of a stress-free assembly for a modern aircraft. This issue holds particularly in the composite material part of large aircrafts. To predict and control this deformation,
a novel method is applied for shifting the relaxation times of the composite based on its temperature and degree of cure. The choice of a suitable material model to simulate induced distortions is important to achieve the right-first-time approach. This work investigates the ability of the
multi-physics model within a linear viscoelastic material model to predict induced distortions into an aerospace composite wing. It is shown that a L-shaped stiffened wall was less dominated by all deformations, but two stiffened wall panels were more dominated. Yet, wing box panels with four
stiffened wall panels reduced the contribution to deformation. Their effects were included in the theory reported for the curing, and found to account for approximately 6.25% of the part deformation. The deformation effect could be analyzed by the proposed analytical solution, which was coupled
with a cure kinetics model and a chemical shrinkage model to capture the multi-physics that take place during the curing.

Authors: Zhan Yunpeng , Hou Shuai , Fu Mingli , Zhao Liyuan , Zhu Wenbo
Published: September 2022

In this paper, polypropylene (PP) and ethylene-octene copolymer elastomers (POE) were used as the matrix resin, and carbon black (CB) and graphene (GNP) were added as conductive fillers. An X-ray diffractometer was used to compare the crystal structure of CB and GNP, and the dispersion
of conductive fillers in the materials were observed by scanning electron microscopy. The relationship between the electrical conductivity of the composite material and the temperature was explored. The effect of graphene on the conductive performance of the shielding material was evaluated.
The results show that the addition of GNP can improve the conductivity of the shielding material at a lower content of conductive fillers; however, at a higher content of conductive fillers, the improvement of the conductivity of the shielding material is insignificant.
Mechanical Properties of Loess and Filling Materials of High-Speed Railway Vibration Isolation Trench in Loess Area
Authors: Song Yulan , Yang Lizhong
Published: September 2022

The special properties of loess make its impact on the vibration propagation of high-speed railways different from other soils. In this study, the static and dynamic characteristics of loess were studied by static and dynamic triaxial tests. The experimental results show that when the
frequency is the same, the dynamic stress-strain relationship curve moves up with the increase of the confining pressure. The frequency has little effect on the initial tangential dynamic modulus of the undisturbed loess. we studied the static and dynamic characteristics of loess and discussed
the implementation methods of viscoelastic artificial boundary and infinite element boundary in high-speed rail dynamic response analysis. The vibration reduction and isolation effect of the trench with different filling materials (the concrete, gypsum, foamed plastic, and rubber) was studied.
The results show that the comprehensive performance of the foamed plastics is better from the perspective of durability and stability of the vibration isolation trench wall. The research results can provide a reference for the selection of filling materials for high-speed railway vibration
isolation trench in loess area.
Tensile Mechanical Properties of Nanowoven Composites Based on Homogenization Theory

Published: September 2022

The nanocomposite is a multiphase material composed of two or more component materials with different properties and different forms through composite means. New material properties. The stress distribution of nano-braided composites in bending is much more complicated than in tension.
Like the tensile condition, the braid angle is still the main factor affecting the bending failure mode. In order to study the tensile strength of nano-braided composites from a microscopic perspective, the nonlinear damage analysis under multiple tensile load steps is carried out in this
paper. The damage analysis results show that the microscopic damage modes of different braided angle composites differ. Based on this, this paper determines the transformation of the failure mechanism to characterize the braided composites. An important parameter—critical braiding angle,
established different tensile strength failure criteria for small braided angle composites and large braided angle composites and numerically predicted the tensile strength of nano braided composites based on these criteria. The value of each stress component increases with the increase of
the braiding angle, and the ratio is about 1:1.25. The strength prediction results are in good agreement with the experimental results.
La Niña Came to Eden
Authors: McPhaden Michael J. , Karamperidou Christina
Published: September 2022

In July 1929, Dr Friedrich Ritter and Dore Strauch left their spouses and the turmoil of post–World War I Germany for the remote, uninhabited, and rugged volcanic island of Floreana in the Galapagos archipelago. Their dream was to live self-sufficiently in an idyllic tropical setting unspoiled by civilization. Wealthy yachters stopping at Floreana in the early 1930s reported on the couple’s pioneering enterprise to the outside world. The news created a sensation that subsequently attracted other settlers, including a mysterious Viennese faux baroness who quickly sowed discord on the island. Not all the participants in this drama survived though. A prolonged drought gripped the island from 1933 to 1935 leading to food shortages that ultimately claimed the life of Dr. Ritter, a vegetarian who unwittingly ate tainted chicken out of desperation. The bizarre intrigues and struggles to endure on Floreana were chronicled in Dore Strauch’s 1936 memoir Satan Came to Eden and a 2013 Hollywood documentary based on it. A story that has not been told is how an extended period of cold La Niña conditions in 1933–35 led to the drought that caused the food shortages. We use an atmospheric reanalysis and other data sources to describe these cold conditions and how they affected the human drama that unfolded on Floreana Island. The protracted La Niña impacted other parts of the globe and in particular was a major influence on development of the 1930s Dust Bowl in the southern plains of the United States.

Authors: Anand Atul , Jha Chandan K. , Singh Prashant K. , Sinha Upasana , Ganesh Abhirami , Bhadani Punam P.
Published: September 2022

A wide range of clinical presentations for Cushing’s syndrome has been described in the literature. Avascular necrosis of femur is a well-recognized complication of excessive glucocorticoid administration, but its occurrence due to endogenous hypercortisolism is rare. We present the case of a 47-year-old male who presented to us with severe low backache, hypertension, uncontrolled diabetes, and other signs and symptoms of Cushing’s syndrome. Hormonal evaluation confirmed hypercortisolism, and a contrast-enhanced computed tomography of the abdomen localized the lesion in the left adrenal gland. Assessment of the severe low back ache—the main symptom for which the patient came to us—by magnetic resonance imaging of the spine and pelvis revealed avascular necrosis of bilateral femoral heads. Resection of the left adrenal gland revealed an adrenocortical carcinoma. To the best of our knowledge, this is only the second case where an adrenocortical cancer leading to hypercortisolism is the cause of avascular necrosis of hip.

The gearbox of the small joint steering gear of a service robot is characterized by a compact structure, a large reduction ratio, and a special manufacturing and assembling technology. However, when a tooth in the gear is broken, the gear transmission can be still maintained, so it is difficult to identify the broken tooth accurately. In order to provide a theoretical basis for the identification of a broken tooth in the study, the influence of gear tooth fracture on the time-varying meshing stiffness in the transmission process was firstly analyzed theoretically and its influencing mechanisms on the time domain and frequency domain characteristics of transmission error (TE) were further analyzed. Then, the TE measurement test bench of the joint steering gear was designed. The signal-to-noise ratios and root-mean-square errors of the TE data processed by wavelet noise reduction, Kalman filtering and combined wavelet-Kalman filtering algorithms were compared and analyzed. The analysis results showed that the joint algorithm had the best performance. Next, the TE data measured under multiple working conditions were processed with the joint filtering algorithm to obtain the time domain results and then the frequency domain results were obtained by Fourier transform. Whether there was a broken tooth in the joint steering gear could be judged based on the difference between the maximum and minimum values of the TE in the time domain. The broken-tooth gear shaft could be positioned based on the frequency of TE mutation waveform. Furthermore, combined with the frequency domain, the accurate identification of the position of the broken gear can be realized. Finally, the accurate positioning method of broken teeth was applied in the product inspection process. Broken teeth were successfully identified and located, thus proving the effectiveness of the identification method.
Changing Paradigms of Territory and Boundary Studies in Political Geography
Authors: Dutta Sayak
Published: September 2022

Boundary studies as a sub-discipline of political geography has undergone several momentous transformations during its evolution. The classical period was predominantly concerned with demarcating the ideal boundary for achieving a stable geopolitical order. This changed during the latter part of the 20th century when scholars began contemplating the role of boundary as a social force. Postmodern understanding of boundaries concerned itself with questions of identity and the narratives of boundary. The focus on territory and territoriality marks another departure from contractual boundary between states to a more cultural notion. In stark contrast to the spatial perception of boundary and territory stands the stream of literature exploring social boundaries investigating the symbolic boundaries that facilitate the social differentiation between various groups of people. The present study comprehensively reviews the three intertwined branches and indicates the need to fuse these traditions and offer suggestions on how to do so. The article also contemplates necessary adaptations to the field going forward.

When analysing bodies recovered from a watery environment, all manners of death, a variety of causes of death and the possibility of body disposal have to be considered. Unclear circumstances of death, unidentified victims and body decomposition may hamper a forensic investigation. The lack of specific and sensitive drowning-related autopsy findings and post-mortem blood alcohol levels (blood alcohol concentrations (BACs)) may also lead to erroneous conclusions. We reviewed the autopsy records for all bodies recovered from water in Friuli, northeastern Italy, over a 28-year period, focusing on death circumstances, autopsy findings and blood alcohol levels. Some unusual cases were examined separately. Among the 69 cases, there were 32 accidents, 13 suicides, 4 homicides, 6 natural and 14 undetermined deaths. Causes of death included 51 drownings, 6 undetermined, 5 cardiac deaths and 7 non-drownings. Six deaths in a bathtub and one diving-related death were also included. Acute alcohol intoxication was ascertained in 22 of 40 victims. Some significant limitations in the approach to water-related deaths have been highlighted: although emphysema aquosum and external foam resulted to be the most reliable indicators, a determination of drowning based exclusively on autopsy findings cannot be ascertained with certainty. Furthermore, it was found that the standard definitions of wet and dry drowning in the literature differ widely from a morphological perspective and this may lead to misleading outcomes. Post-mortem BAC changes have been critically analysed only in bodies found in cold water, and, in the absence of an alternative to blood specimens, the use of pre-set cut-off values is still necessary.
The Canadian approach to elder financial abuse from a legal and clinical perspective: A narrative review
Authors: Carr Frances
Published: September 2022

Elder financial abuse is a growing problem, with significant consequences for society. It is unclear if differences exist in the clinical and legal approach to financial abuse across Canada, thus the purpose of this review. Five databases were searched during the primary literature search. Secondary literature search involved searching grey literature and handpicking references from selected articles. Only articles in English were included. From 10,260 articles initially screened, 30 were included in the review. No literature was identified describing differences in the clinical approach to financial abuse, and no single definition or legislation on financial abuse was identified. Mandatory reporting is required for individuals in a hospital or care facility by only five provinces. This review has identified several important knowledge gaps on the differences in the clinical management of financial abuse, and a lack of definition, legislation and overall mandatory reporting across Canada, which requires further research.
It IS Who You Know: The Power of Supervisors in Awarding and Administering Bereavement Leave
Authors: Tonkin Kent
Published: September 2022

Within this study, the researcher explored the effect that supervisors have on the availability and flexibility of bereavement leave for employees who have experienced the death of a loved one. A qualitative phenomenological approach was applied in Zoom interviews of 23 participants who provided detailed feedback on their overall experience of managing personal and professional responsibilities during bereavement based on the ways that formal and informal policies were applied. Barclay and Kang’s bereavement at work model guided a series of semi-structured interviews, and questions were based upon Bauer’s questionnaire about grief in the workplace. A high number of participants (20/23) noted that their relationship with their supervisor either positively or negatively affected their experience with workplace bereavement policies. Four overall themes were noted: general importance of relationship with supervisor, supervisor flexibility in awarding leave, employee perception of organizational justice, and supervisor control of information.

Published: September 2022

Background: This study aimed to assess the impact of the COVID-19 pandemic in terms of the prevalence of anxiety, depression and stress symptoms in Italian medical students and to identify the associated factors.

Design and Methods: A cross-sectional online survey was administered to second-sixth year medical students of the University of Torino, collecting data on the students’ sociodemographics, COVID-19 exposure, anxiety, depression and stress symptoms. Three hierarchical regressions adjusted for age, gender and year of study were executed.

Results: The sample size was 1359. The prevalence of anxiety, depression symptoms, moderate perceived stress and severe perceived stress was 47.8%, 52.1%, 56.2% and 28.4%, respectively. The factors associated with mental health symptoms were: being a woman, a family history of psychiatric disorders, living off-site, competitive/hostile climates and unsatisfying friendships among classmates, poor relationships with cohabitants, negative judgment of medical school choice, fear of COVID-19 infection, feelings of loneliness, distressing existential reflections, and a worsening psychological condition related to the pandemic. Being in the fourth or sixth year constituted a protective factor for depression symptoms.

Conclusions: Mental health in medical students was associated with both COVID-independent and COVID-related factors. Accessibility to effective interventions must be increased to counteract these changes.
How Craniofacial Anomalies Can Obscure the Diagnosis of Unilateral Auditory Neuropathy Spectrum Disorder: A Case Study
Authors: Sevier Joshua D.
Published: September 2022

Comorbidities are common with craniofacial anomalies and can include auditory neuropathy spectrum disorder (ANSD). Identification of these comorbidities, such as a diagnosis of ANSD, has increased with expanded multi-disciplinary care teams and the use of auditory objective measures. Patients with craniofacial anomalies often have complex medical histories including extreme prematurity and jaundice, which may lead to the development of additional comorbidities. The 5-year-old boy that is the subject of this case study presented with noted developmental delays and residing in foster care with an unknown family/medical history. Initially presenting with middle ear dysfunction, exacerbated by craniofacial anomalies, the underlying cause of his speech delays was missed. Behavioral audiometry was attempted with inaccurate results. Surgery was performed to correct the craniofacial anomalies, middle ear dysfunction, and was followed with auditory brainstem response (ABR) testing. The boy healed well without complications. The ABR revealed ANSD, hearing aids were fitted for the diagnosis, regular speech therapy was initiated, and the boy continues to make steady progress toward developmental milestones. The purpose of this case study was to highlight the course of identification and treatment of a complex case that may provide insight into determining a differential diagnosis of ANSD when initially obscured by craniofacial anomalies.

Background

The effect of dietary patterns on sleep disorders and mental illness has previously been investigated. However, these studies have reported contradictory findings, and thus, the present study aimed to assess the association of the MIND diet on the sleep pattern and mental health in obese women.

Methods

This is a cross-sectional study in which 282 women, aged 18–56 years with BMI ≥ 25 kg/m2.with no underlying diseases and malignancies, and participated. We used a semi-quantitative food frequency questionnaire (FFQ) to collect participant's dietary intake. The Pittsburgh Sleep Quality Index (PSQI) and Depression Anxiety Stress Scales (DASS) were used to measure the status of sleep disturbance and psychological disorders, including depression, anxiety, and stress respectively.

Results

A decreasing trend for psychological stress was observed in the highest quartiles of MIND diet score vs. the lowest quartiles (OR = 0.6 CI: 0.23–1.5 vs. 1.16 CI: 0.55–2.47). No significant difference was observed between severity of depression (OR = 0.87 95%, CI: 0.7–1.09, P = 0.23), anxiety (OR = 1.02, 95% CI: 0.81–1.27, P = 0.86), stress (OR = 0.99 95%, CI: 0.79–1.23, P = 0.92), and MIND diet adherence in the crude and adjusted models.

Conclusion

The main finding from this study was that there is no significant association between adherence to the MIND diet and studied psychological disorders.
