Influence of Night Shift Work on Heart Rate Variability in an Age- and Gender-Matched Study Group.

Regular and long-term shift work is associated with a number of chronic diseases. There is some evidence that shift work also has an influence on the autonomous nervous system. Studies that have examined the effect of shift work on heart rate variability (HRV) have not taken into account age and gender. Therefore, the aim of this study was to investigate the influence of night shift based on 24 h long-term analyses carried out on non-night shift days with a matched control group for age and gender. In total, 172 (128 male, 44 female) healthy shift night workers were compared with subjects from a non-night shift worker group at a ratio of 1:1, forming matched pairs based on the subjects' sex and age. HRV parameters were analyzed based on 24 h ECG recording. An analysis of the HRV parameters showed only a small difference but without statistical significance between the two groups with regard to all of the HRV parameters examined (SDNN, RMSSD, NN50, pNN50, VLF, LF, HF, LF/HF, DFA1, and DFA2). An analysis of the subgroup of subjects who had only worked night shifts for a minimum of 10 or 20 years, with the respective pairs matched by age and gender, did not reveal any significant differences between the HRV parameters of employees working night shifts and those not working night shifts. Taking into account qualitative aspects of HRV analysis, this study was thus able to show that working night shifts for many years may not have as big an influence on HRV as had been assumed so far.

Age-Related Differences in Prestimulus EEG Affect ERPs and Behaviour in the Equiprobable Go/NoGo Task.

Detailed studies of the equiprobable auditory Go/NoGo task have allowed for the development of a sequential-processing model of the perceptual and cognitive processes involved. These processes are reflected in various components differentiating the Go and NoGo event-related potentials (ERPs). It has long been established that electroencephalography (EEG) changes through normal lifespan development. It is also known that ERPs and behaviour in the equiprobable auditory Go/NoGo task change from children to young adults, and again in older adults. Here, we provide a novel examination of links between in-task prestimulus EEG, poststimulus ERPs, and behaviour in three gender-matched groups: children (8-12 years), young adults (18-24 years), and older adults (59-74 years). We used a frequency Principal Component Analysis (f-PCA) to estimate prestimulus EEG components and a temporal Principal Component Analysis (t-PCA) to separately estimate poststimulus ERP Go and NoGo components in each age group to avoid misallocation of variance. The links between EEG components, ERP components, and behavioural measures differed markedly between the groups. The young adults performed best and accomplished this with the simplest EEG-ERP-behaviour brain dynamics pattern. The children performed worst, and this was reflected in the most complex brain dynamics pattern. The older adults showed some reduction in performance, reflected in an EEG-ERP-behaviour pattern with intermediate complexity between those of the children and young adults. These novel brain dynamics patterns hold promise for future developmental research.

Assessment of phonemic verbal fluency in Portuguese patients with multiple sclerosis

ABSTRACT Background Executive dysfunction occurs in 15% to 20% of multiple sclerosis (MS) patients and verbal fluency tests are frequently used to assess this deficit. The Word List Generation (WLG) is one of the most used measures in MS. This study aims to compare the performance of WLG of MS patients and healthy controls and to analyze the influence of clinical and demographic factors on the performance of MS patients. Methods One hundred and nine MS patients and an age- and gender-matched group of 138 healthy controls were evaluated with WLG Portuguese version, as well as other tests from the Brief Repeatable Battery of Neuropsychological Tests (BRBN-T), subtests from WAIS, a phonemic fluency test (M, R, and P), and measures of psychological symptomatology and cognitive fatigue. The MS group (70.6% females) was mainly diagnosed with RRMS (89.2%). Results The MS group performed significantly lower than healthy controls on the WLG. In the MS group, this performance was significantly correlated with the level of education. Significant differences were found between the two groups regarding cognitive fatigue, with MS patients reporting higher levels than healthy controls. However, this variable was not related to the performance on the WLG for MS patients. Conclusions This study suggests that MS is associated with large levels of cognitive decline on the phonemic verbal fluency tests. These results are consistent with other studies and highlight the importance of verbal fluency and cognitive speed measures in the neuropsychological assessment of MS. Deficits on this task seem to be highly related to the level of education of the patient rather than other demographic and clinical factors.

Adenotonsillectomy outcomes in children with down syndrome and obstructive sleep apnea: a single center study.

This study aimed to evaluate polysomnographic (PSG) outcomes of tonsillectomy and adenoidectomy (T&A) in children with Down Syndrome (DS) and OSA, and the difference in PSG outcomes of T&A between children with DS and age- and gender-matched normally developing (non-DS) children. This was a single center retrospective study that included children with DS and OSA who underwent T&A and had pre-operative and post-operative PSG. The baseline and the differences of pre- and post-operative PSG variables were compared with those of an age- and gender-matched group of non-DS children. Forty-eight children with DS were included in the study; the median age was 5 years (IQR 5.5), 58% were males, and the median BMI was 18.2 (IQR 3.3). There was statistically significant improvement noted between pre-operative and post-operative OAHI 17.9 ± 26.7 vs. 9.1 ± 13.6 (p = 0.022) and non-REM AHI 13.9 ± 19.7 vs. 6.9 ± 14.2 (p = 0.027). However, there were no significant changes in sleep architecture, oxygen desaturation nadir, or CO2 levels. 54.2% of the DS children continued to have moderate to severe OSA after T&A. Univariate logistic regression showed that for every 1% increase in oxygen desaturation nadir, the odds of having residual moderate or severe OSA decreased by 28% (p = 0.002) compared to the cured and mild OSA groups. There was no significant pre- and post-operative differences in PSG variables noted in 16 children with DS compared to age- and gender-matched non-DS children. Despite the overall significant reduction of OAHI in children with DS and OSA who underwent T&A, there was a residual moderate to severe OSA in about half of the included children. Oxygen desaturation nadir was a predicting factor for persistent moderate to severe OSA. There were no significant pre- and post-operative PSG differences in between DS children compared to non-DS children.

Does dysautonomia contribute to inappropriate sinus tachycardia in patients with post-COVID-19 syndrome?

Abstract Funding Acknowledgements None. Introduction Post-COVID-19 syndrome (PCS) refers to a wide spectrum of health issues experienced by individuals who have previously had COVID-19, starting three months after acute COVID-19 and enduring for a minimum of two months. Approximately 20% of PCS patients encounter inappropriate sinus tachycardia (IST), defined as the mean 24-hour heart rate greater than 90 bpm. IST is often accompanied by symptoms including palpitations and breathlessness that hinder patients in their daily tasks. Previous research has suggested that dysautonomia, a dysfunction in the autonomic nervous system, might underlie most PCS symptoms. Yet, its role in the development of IST within the context of PCS has not been fully investigated. Purpose This retrospective study examines IST prevalence and cardiovascular symptoms in PCS patients. It also assesses cardiac autonomic function through analysing the time and frequency fluctuations between successive heart rates, termed heart rate variability, to investigate the role of dysautonomia in the development of IST in PCS. Methods Patients who continued to experience PCS symptoms 12 weeks after their initial SARS-CoV-2 infection were referred to a multidisciplinary PCS unit at our hospital. Using our electronic patient record system, we identified 685 eligible patients who underwent 24-hour Holter monitoring between March 2020 and February 2023. After excluding patients with various conditions that could affect heart rate, we performed a comparative sub-analysis on 524 patients, dividing them into two age- and gender-matched groups of IST (n=100) and non-IST (n=424). The ECG data extracted from the 24-hour Holter records of these patients were entered into the KUBIOS software for HRV analysis and assessment of sympathetic and parasympathetic activity which could indicate cardiac dysautonomia. Demographic data was analysed using basic descriptive statistics and a chi-square test between the two groups. The normality of each parameter was tested using the Shapiro-Wilk test. Using Mann-Whitney and unpaired t-tests, we statistically analysed the differences between the IST and non-IST groups on the GraphPad Prism software. Results The LF/HF ratio was significantly higher in the IST group (2.78 ± 1.89) compared to the non-IST group (2.15 ± 1.93, p<0.001). The sympathetic nervous system (SNS) index was significantly higher in the IST group (1.50 ± 0.77 versus -0.13 ±0.70, p<0.001), whilst the parasympathetic nervous system (PNS) index was significantly lower in the IST group (-1.75 ± 0.65 versus -0.16 ± 1.61, p<0.001). Conclusions In PCS patients with IST, cardiac dysautonomia leads to a shift in the cardiac sympathovagal balance towards PNS and subsequently increased SNS activity, with a more pronounced effect on the parasympathetic side. Addressing dysautonomia and promoting parasympathetic activity could thereby improve PCS diagnostic and treatment strategies to restore a balanced autonomic regulation of the heart.

Comparison the Voice Onset Time (VOT) of Postlingual Cochlear Implant Users and Normal Peers in the CAPE_V Sentences as Continues Speech Task

BackgroundAuditory perception plays a crucial role in speech and language development, emphasizing concerns about hearing loss. While cochlear implantation nearly tackles challenges associated with post-lingual hearing loss in adults, the importance of "auditory feedback" and acoustic assessment becomes crucial for evaluating speech disorders and devising effective treatments. This study aims to address the gap in assessing Voice Onset Time (VOT) as an indicator of nuanced variations in the speech of cochlear implant users during a continuous speech task. MethodRecordings of Persian CAPE-V sentences were obtained from 25 cochlear implant (CI) users and 25 healthy speakers, with a mean age of 33.2 years (SD=11.5, range=18-55 years). Ten words, incorporating both voiced and voiceless consonants, were selected from the CAPE-V sentences. VOT measurements for the specified stop consonants at the initial syllables of these chosen words were computed using PRAAT. A comparative analysis between the two age- and gender-matched groups was conducted using an independent sample t-test. Subsequently, ANCOVA was employed to examine the influence of demographic factors on VOT values among CI participants. ResultsUnvoiced consonant /p/ in /po/, /pɑ/, /pe/, and /pa/ syllables had higher VOT values in the healthy group, while the voiced consonant /d/ in /da/ and /di/ syllables demonstrated higher VOT values in the CI group. (P<0.05) Apart from /po/ and /di/ syllables, no significant impacts of demographic factors on VOT values were observed (P≥0.8). ConclusionDespite the improvement in speech quality after cochlear implantation, subtle differences persist. The motor theory, which underscores the impact of auditory inputs on temporal coordination, highlights the role of VOT in speech discrimination. Various linguistic factors affect VOT, including articulation position, vowel context, and raised vowels. While CI enhances syllable distinction, challenges in articulation for adults suggest a need for targeted training in rehabilitation programs, ultimately enhancing the quality of life for CI users.

Investigating the interplay between gaming disorder and functional impairments in professional esports gaming

The relationship between Gaming Disorder (GD) and the experience of functional impairments has received considerable theoretical attention in the recent past and current diagnostic approaches underscore the centrality of functional impairments as a requirement for GD diagnosis. However, there is limited empirical evidence illuminating the interplay between GD and functional impairments, particularly among specific vulnerable groups. The present study seeks to bridge this gap by investigating an English-speaking sample (N = 5198) comprising an age- and gender-matched group of Professional Gamers (PG, n = 2599) and Non-Professional Gamers (NPG, n = 2599) sub-sampled from a larger sample of 192,260 individuals. The results revealed that PG were at a greater risk for GD compared to NPG as the prevalence rate of GD among PG (3.31%) was significantly higher and almost doubled that of NPG (1.73%), with PG further exhibiting higher overall GD symptom-load and weekly time spent gaming compared to NPG. Furthermore, PG reported experiencing significantly higher frequency of gaming-related functional impairments compared to NPG, with the in particular affected areas for both PG and NPG being ‘school and/or work’, ‘physical health’, and ‘family’, with other key differences emerging in relation to other outcomes. Overall, the present findings show that not only GD symptom-load but also some functional impairment is higher in PG compared to NPG which highlights the need to develop and support prevention and intervention strategies for this at-risk population.

Differences in gut microbiota between Dutch and South-Asian Surinamese: potential implications for type 2 diabetes mellitus

Gut microbiota, or the collection of diverse microorganisms in a specific ecological niche, are known to significantly impact human health. Decreased gut microbiota production of short-chain fatty acids (SCFAs) has been implicated in type 2 diabetes mellitus (T2DM) disease progression. Most microbiome studies focus on ethnic majorities. This study aims to understand how the microbiome differs between an ethnic majority (the Dutch) and minority (the South-Asian Surinamese (SAS)) group with a lower and higher prevalence of T2DM, respectively. Microbiome data from the Healthy Life in an Urban Setting (HELIUS) cohort were used. Two age- and gender-matched groups were compared: the Dutch (n = 41) and SAS (n = 43). Microbial community compositions were generated via DADA2. Metrics of microbial diversity and similarity between groups were computed. Biomarker analyses were performed to determine discriminating taxa. Bacterial co-occurrence networks were constructed to examine ecological patterns. A tight microbiota cluster was observed in the Dutch women, which overlapped with some of the SAS microbiota. The Dutch gut contained a more interconnected microbial ecology, whereas the SAS network was dispersed, i.e., contained fewer inter-taxonomic correlational relationships. Bacteroides caccae, Butyricicoccus, Alistipes putredinis, Coprococcus comes, Odoribacter splanchnicus, and Lachnospira were enriched in the Dutch gut. Haemophilus, Bifidobacterium, and Anaerostipes hadrus discriminated the SAS gut. All but Lachnospira and certain strains of Haemophilus are known to produce SCFAs. The Dutch gut microbiome was distinguished from the SAS by diverse, differentially abundant SCFA-producing taxa with significant cooperation. The dynamic ecology observed in the Dutch was not detected in the SAS. Among several potential gut microbial biomarkers, Haemophilus parainfluenzae likely best characterizes the ethnic minority group, which is more predisposed to T2DM. The higher prevalence of T2DM in the SAS may be associated with the gut dysbiosis observed.

AFG3L2 and ACO2-Linked Dominant Optic Atrophy: Genotype–Phenotype Characterization Compared to OPA1 Patients

PurposeHeterozygous mutations in AFG3L2 gene (encoding a mitochondrial protease indirectly reflecting on OPA1 cleavage) and ACO2 gene (encoding the mitochondrial enzyme aconitase) are associated to isolated forms of Dominant Optic Atrophy (DOA). We aimed at describing their neuro-ophthalmological phenotype as compared with classic OPA1-related DOA. DesignCross-sectional study. MethodsThe following neuro-ophthalmological parameters were collected: Log MAR visual acuity (VA), color vision, mean deviation and foveal threshold at visual fields, average and sectorial retinal nerve fiber layer (RNFL) and ganglion cell layer (GCL) thickness at optic coherence tomography. ACO2 and AFG3L2 patients were compared with an age- and gender-matched group of OPA1 patients with 1:2 ratio. All eyes were analysed using Clustered Wilcoxon rank sum test using Rosner-Glynn-Lee method. Results44 eyes from 23 ACO2 and 26 eyes from 13 AFG3L2 patients were compared with 143 eyes from 72 OPA1 patients. All cases presented with bilateral temporal-predominant optic atrophy with various degree of visual impairment. Comparison between AFG3L2 and OPA1 failed to reveal any significant difference. ACO2 patients compared to both AFG3L2 and OPA1 presented overall higher values of nasal RNFL thickness (p=0.029, p=0.023), average (p=0.012, p=0.0007) and sectorial GCL thickness. These results were confirmed also comparing separately affected and subclinical patients. ConclusionsClinically, DOA remains a fairly homogeneous entity despite the growing genetic heterogeneity. ACO2 seems associated to an overall better preservation of retinal ganglion cells, probably depending on the different pathogenic mechanism involving mtDNA maintenance, as opposed to AFG3L2, which is involved in OPA1 processing and resulted virtually indistinguishable from classic OPA1-DOA.

Concomitant Tricuspid Valve Surgery Is Not Associated With Increased Operative Risk During Robotic Mitral Valve Surgery.

The aim of this study was to investigate the outcomes of robotic mitral valve surgery with and without concomitant tricuspid valve surgery. Patients who underwent robotic mitral surgery between March 2010 and September 2022 were included. Patients were grouped according to the presence of concomitant tricuspid interventions. The groups were compared for baseline factors, operative parameters, and early postoperative outcomes. Age- and gender-matched groups were also compared for outcomes. The study included 285 robotic mitral surgery patients. There were 59 patients who underwent concomitant tricuspid interventions. In the concomitant tricuspid surgery group, cardiopulmonary bypass time (150.1 vs 128.4 min, P < 0.001) and cross-clamp time (99.2 vs 82.4 min, P < 0.001) were longer. Prolonged intubation was more frequent in the concomitant tricuspid intervention group (5.2% vs 0.5%, P = 0.029). The groups did not differ in terms of mortality, permanent pacemaker (PPM) requirement, or other morbidities. Perioperative outcomes were similar after matched group analysis. Operative mortality and early adverse outcomes did not increase with the addition of tricuspid intervention in our cohort of robotic mitral surgery patients. The robotic approach for mitral disease and coexisting tricuspid disease may offer safe results without an increased risk of postoperative PPM requirement.

A Multicentric Cross-Sectional Observational Study to Analyze the Effects of Moderate High Altitude on Ocular Health.

Prolonged exposure to hypoxia at high altitudes can affect the eyes through various mechanisms, culminating in reduced vision. Multiple studies on this subject have focused on the ocular effects of high altitude on intraocular pressure (IOP), corneal thickness, and the retina. However, there is a lack of literature on the effects of 'moderate high altitude (2000-3000 m)' on the eyes. Hence, we designed our study to determine the impact of moderate high altitude on the eyes. We recruited two age and gender-matched groups of 250 research participants, each at moderate high altitude (Group A) and plains (Group B), respectively, to determine the effects of moderate high altitude on ocular health, if any. We found a statistically significant increase in dry eye in Group A. We also found four cases of central serous retinopathy and one case of central retinal vein occlusion in Group A. There was no statistically significant change in visual acuity, IOP, or central corneal thickness. There is a vast lacuna in the literature on this particular altitude range, and further studies are required to confirm our findings. It is also recommended that lubricant eye drops be advised as a standard prophylactic measure for all individuals traveling and staying at moderate high altitude.

Meteorin-like protein elevation post-exercise improved vascular inflammation among coronary artery disease patients by downregulating NLRP3 inflammasome activity.

Coronary artery disease (CAD) has become the most common cause of death worldwide. However, the negative effects of CAD are able to be alleviated via exercises, possibly via increased production of meteorin-like protein (Metrnl). In this study, we aim to evaluate the connection between Metrnl production during exercise with lowered CAD risk and severity. Two age and gender-matched groups of 60 human patients, one with CAD, and one without were randomly recruited. The CAD group were subjected to continuous training exercises. Mice were exercised by using a treadmill, establishing an animal exercise model. ELISA was used to measure plasma Metrnl and inflammatory factors. To determine the impact of Metrnl on glucose metabolism, oxygen consumption and extracellular acid rates were taken for untreated, palmitic acid (PA)-treated, and PA+Metrnl co-treated human umbilical vein endothelial cells. Western blot was used to measure expression levels for the NLR family pyrin domain containing 3 inflammasome. CAD patients had lower Metrnl levels compared to non-CAD controls. Furthermore, higher Metrnl levels post-exercise were inversely associated with LDL, inflammatory cytokines, and CAD severity, as well as being positively associated with HDL. Metrnl was able to counteract against PA-induced HUVEC glucose metabolic dysfunction via reducing ROS production, which in turn lowered NLRP3 inflammasome expression, thereby serving as the basis behind the inverse correlation between Metrnl and inflammatory cytokines. Exercise was able to increase Metrnl production from skeletal muscle among CAD patients, and subsequently improve patient atherosclerosis via counteracting against endothelial metabolic dysfunction and pro-inflammatory activities.

Cross-cultural adaptation of assessments for time-related abilities of Indian older adults and evaluation of their reliability and validity

Background Older adults may have difficulties in daily time management due to age-related or disease-related cognitive impairment. Standardised assessments for time-related abilities are currently unavailable in India. Aim The study aimed to adapt the Kit for Assessing Time-processing Ability–Senior (KaTid-Senior) and Time-Self rating, Senior (Time-S Senior) for daily time management of Indian older adults, translate these into an Indian language, and evaluate the reliability and validity of the adapted assessments. Materials and methods The two Swedish-origin assessments were reviewed, adapted for linguistic and cultural relevance into English, and translated into Kannada language. Older adults (n = 128) were conveniently selected, assessed with the Montreal Cognitive Assessment, and assigned to age and gender-matched groups: cognitively-impaired and cognitively-normal. Data was then collected with the adapted assessments. Results Both adapted assessments demonstrated acceptable reliability (internal consistency) in this sample (α =0.89 − 0.90). The cognitively-impaired group had significantly (p < 0.001) lower scores on the assessments as compared to the cognitively-normal group. There was a strong to moderate correlation between the assessments supporting their convergent validity. Conclusions The adapted assessments are reliable and valid in the Indian context. Significance The study would facilitate contextually-relevant assessment and management of time-related abilities in Indian older adults.

The effect of long-term use of methylphenidate on cardiac autonomic functions and ventricular arrhythmogenesis: a prospective case-control study.

We aimed to assess cardiac autonomic balance with heart rate variability by using 24-hour Holter electrocardiography and also to assess susceptibility to ventricular arrhythmias by using microvolt T wave alternance in children with attention deficit hyperactivity disorder. This study was conducted with age- and gender-matched groups of 40 patients taking long-acting methylphenidate for more than a year and 55 healthy controls. Heart rate variability analysis for cardiac autonomic functions and microvolt T wave alternance measurements for susceptibility to ventricular arrhythmias were evaluated by 24-hour Holter electrocardiography. The mean age 10.9 ± 2.7 years, mean duration of therapy 22.76 months, and mean methylphenidate doses were 37.64 mg/day. The study group had considerably higher rMSSD, higher HF, and a lower LF/HF ratio (respectively, p : 0.02, p : 0.001 and p : 0.01). While parasympathetic activity parameters were elevated, sympathetic activity parameters were low during the sleep period. Increase in the microvolt T wave alternance values of the study group was not found to be statistically significant (p > 0.05). In children taking long-acting methylphenidate, the autonomic balance was shown to be in favour of the parasympathetic system. Determination of the vulnerability to life-threatening ventricular arrhythmias has been evaluated for the first time in children with attention deficit hyperactivity disorder. Accordingly, microvolt T-wave alternance values give the notion that drug use is safe.

Influence of Modified Instructions on Locomotion Subtest Scores Using the Peabody Developmental Motor Scales, Second Edition.

The current study assessed whether changes in verbal and visual cues used to clarify requirements of the task would result in significant score differences on the Locomotion subtest of the Peabody Developmental Motor Scales, Second Edition (PDMS-2), in children aged 2.5 to 5 years. The Locomotion subtest of the PDMS-2 was administered twice, 2 to 10 days apart, to 37 children. Age-matched and gender-matched groups received instructions in both standardized and modified formats, where order depended on group assignment. Instruction type resulted in a significant change in Locomotion scores with a medium effect size and no significant interactions between instruction type and age or between instruction type and test order. Findings suggest instruction modifications using altered verbal and visual cues change PDMS-2 Locomotion subtest scores in children with typical development. These results support previous literature indicating that normative scores should not be reported if modifications were used during testing.

Three-dimensional radiographic features of craniometaphyseal dysplasia—a comparative CBCT study

PurposeCraniometaphyseal dysplasia (CMD) is a rare skeletal disorder that has progressive thickening and increased density of the craniofacial bones along with abnormal metaphyses of the long bones. Other features include a wide nasal bridge, paranasal bossing, hypertelorism, and an increase in the zygomatic width. We present a series of cases that showcase the three-dimensional radiographic features of this rare condition and compare it with an age and gender-matched controlled group using cone beam computed tomography (CBCT).ObjectiveTo evaluate the three-dimensional radiographic features of craniometaphyseal dysplasia (CMD).Materials and methodsRetrospective analysis of CBCT scans of 7 patients who were diagnosed with the rare condition craniometaphyseal dysplasia was evaluated. Radiographic features of the craniofacial bones, the paranasal sinuses prominently maxillary, and frontal and sphenoid sinuses were evaluated. Skull bones were also evaluated, and the size and shape of the sella turcica and external auditory meatus were measured. Retained primary teeth and impactions were evaluated using a panoramic reformatted image. The type of occlusion and buccolingual dimensions of jaw bones were also assessed. Age and gender-matched control samples were used to measure the same features for comparing CMD patients to healthy controls. The quality of normal and syndromic patients’ cortical and trabecular bone was determined by measuring pixel intensity values (PIV) generated by CBCT scans.ResultsCone beam CT images of patients with CMD were analyzed to evaluate cranial bones, their density, and any abnormalities associated with the sinuses and foramina. Patients with CMD had bones increased in size. A significant increase in the amount of bone formed was found in the inner table of the frontal and occipital bones. All seven patients with CMD had smaller foramina due to the deposition of sclerosed bone in the foramina of the skull base. The paranasal sinuses, prominently maxillary and frontal and sphenoid sinuses, were smaller than the age and gender-matched controls. The buccolingual dimensions of jawbones were increased. The maxillary and mandibular arch relationship ranged from class II to class III. The mean nasal bridge measurement for the CMD patients was 26.77 mm, while in the controls, the mean nasal bridge measurement was 19.48 mm. The mean measurements of the right and left orbits of CMD patients were 30.6 mm and 31.07 mm respectively, and the mean measurements of the right and left orbits of controls were 32.45 mm and 32.04 mm. Pixel intensity values (PIVs) representing density ranged between 100 and 1000 PIVs for cortical bone and between − 60 and 258 for trabecular bone suggesting a densely sclerotic texture, while in the control group patients, the PIVs for cortical bone were > 1000 and 150–300 for trabecular bone.ConclusionCMD patients had significantly larger bone widths, a lower density of the bone, and smaller sinuses compared to the control group.

Nasal Polyposis and Serum Albumin: Systemic Effects of Local Inflammation.

Introduction The genesis of chronic rhinosinusitis is always a topic of debate. A polyp is a pale, edematous tissue emerging mostly from the middle meatus. An epithelial injury caused by continuous inflammation of the nasal mucosa is considered to be a possible cause of the genesis of nasosinusal polyps. Objective To understand the link between serum albumin levels and nasal polyposis. Methods A retrospective study of 180 consecutive patients between January 2016 and January 2020 at our center. We then divided the patients into three age- and gender-matched groups: 60 patients with chronic rhinosinusitis with nasal polyposis, 60 patients with chronic rhinosinusitis without nasal polyposis, and a control group with 60 patients. No patient had a history of any pathology that could alter serum albumin. We then compared the level of serum albumin between the three groups. Results The group of patients with rhinosinusitis and nasal polyposis consisted of 60 patients with a serum albumin value of 4.49 ± 0.29 g/dL, whereas in the control group, the serum albumin value was 4.67 ± 0.2 g/dL. We found a significant difference between the group with nasal polyposis and the other two groups evaluated: chronic rhinosinusitis without nasal polyposis (p<0.001) and the control group (p<0.001). Conclusions Lower levels of serum albumin can be seen in patients with chronic rhinosinusitis with nasal polyposis. Further studies should aim to apply its value since it is a non-expensive marker, to the follow-up of those patients or even to stratify them according to their endotype.

The dietary risk factors on cancer patients receiving chemotherapy and correlation between serum vitamin D and B12 levels, depression and anxiety status.

Objective: the aim of this study is to evaluate the relationship between serum vitamin D and B12 levels, nutritional levels, depression, and anxiety in adult cancer patients before and after chemotherapy. Methods: a case-controlled study was carried out on 44 patients who were diagnosed with cancer and applied to the Chemotherapy Unit for treatment (patient group, PG) and 44 volunteer individuals (control group, CG) with similar characteristics to the age and gender-matched patient group but with no diagnosis of cancer. Results: the average age of individuals in PG is 52.50 ± 12.21 years and for those in CG is 52.84 ± 10.98 years. Serum D and B12 levels in the first cure in individuals in PG are higher than in the last treatment (p > 0.05). It was determined that vitamin C taken with a daily diet reduces the risk of cancer (OR: 0.920, 95 % CI: 0.899-0.942, p = 0.042). No correlation was found between depression and anxiety scores of both groups and serum vitamin D and B12 levels (p > 0.05). It was determined that the Beck Anxiety Inventory (BAI) score increased with decrease in body mass index (BMI) (β = 0.311, p = 0.040) and serum vitamin B12 level (β = -0.406, p = 0.006). In addition, it was found that the increase in the Patient-Generated Subjective Global Assessment (PG-SGA) score, which reflects the nutritional status of cancer patients, worsened the level of anxiety (β = 0.389, p = 0.009). Conclusions: as stated in the findings of the study, chemotherapy treatment mediated the development of anxiety in cancer patients by changing the vitamin B12 levels and anthropometric characteristics with its negative effect on nutritional status. It should be ensured that cancer patients treated with chemotherapy follow a healthy and balanced diet plan that is suitable for their needs and has adequate vitamin and mineral content.

Risk of Fractures, Repeated Fractures and Osteoporotic Fractures among Patients with Hemophilia in Taiwan: A 14-Year Population-Based Cohort Study

The world is aging, and hemophilia patients are as well. The association between patients with hemophilia (PWH) and low bone mineral density is clear. However, the incidence of fractures in patients with hemophilia is inconclusive, and no research has yet explored repeated fractures among PWH. In this study, we investigated the incidence of all-site fractures, repeated fractures and osteoporotic fractures amongst PWH. The study compared the incidence of all-site fractures, repeated fractures and osteoporotic fractures occurring in all PWH who were enrolled in Taiwan's National Health Insurance Research Database between 1997 and 2013 with an age- and gender-matched group from the general population. Eight-hundred thirty-two PWH, along with 8320 members of the general population, were included in the final analysis. After multivariate COX regression analysis with an adjustment for confounding factors, it was found that PWH experienced a higher risk of osteoporotic fracture (HR: 1.25 with 95% CI of 1.03-2.52) but only saw a neutral effect with regards to both all-sites of fracture (HR: 1.00 with 95% CI of 0.92-1.09) and repeated fractures (HR: 1.01 with 95% CI of 0.92-1.10), when compared with the general population. This 14-year population-based cohort study showed that PWH had a higher risk of osteoporotic fracture, but that hemophilia only had a neutral effect in all-sites of fracture and repeated fractures. Screening, prevention and treatment for osteoporosis and further osteoporotic fractures among PWH, in order to improve quality of life and achieve healthy aging in this particular population, remain essential.

Increased Prevalence of Sensory Processing Issues in Pediatric Gastrointestinal Patient Population.

Background Sensory processing dysfunction in children has been linked to attention-deficit/hyperactivity disorder, autism, feeding disorders, and functional abdominal pain. However, little is known about sensory processing in the broader pediatric gastroenterology population. Objective To characterize frequency and type of sensory processing dysfunction seen in pediatric gastroenterology compared to a general pediatric population. Methods The Short Sensory Profile 2 was administered to the parents of children ranging 3-14 years, being seen in a pediatric gastrointestinal (GI) subspecialty clinic or general pediatric clinic. Short Sensory Profile 2 scores from age- and gender-matched groups were compared with nonparametric statistics. Results Sensory processing dysfunction was increased in children seen in the GI clinic compared to children in the general pediatric clinic. Short Sensory Profile 2 quadrant analysis revealed greatest differences in avoiding, primarily in young females of the GI population. Conclusion Children presenting to a pediatric GI clinic demonstrate greater sensory processing dysfunction compared to children in a general pediatric practice.
