Integrated care program for patients with dementia and behavioural disorders in the home setting.

Introduction: Behavioural symptoms involve suffering and functional worsening of people with dementia, overburden their caregivers and increase emergency department visits, hospitalizations and early institutionalizations.
 Objectives And Who It Is For: To evaluate the results of an interdisciplinary intervention to improve the control of behavioural symptoms in elderly people with dementia receiving chronic care at home.
 Who We Involved And Engaged With: Representatives of general practitioners, home care specialists, geriatricians, psychiatrists, healthcare managers, and patients and families voice through claims and suggestions. The first pilot was adapted considering patients’ needs and acceptance.
 Materials And Methods (What We Did): before-after quasi-experimental study with own individual as control. Inclusion criteria: admission to the Home Medicine section between 06/01/2021 and 09/30/2022, age older than 64 years; and major cognitive impairment with behavioural disorders of complex management for the attending physician; or need for adequacy of psychotropic drugs during the transition of care for having suffered an acute confusional syndrome during hospitalisation. Exclusion criteria: history of psychosis or life expectancy of less than six months.
 Intervention: Provision of care by a health care team coordinated by a geriatrician via telemedicine, the home follow-up physician and a health and social care counsellor (comprehensive gerontological assessment). The geriatrician agreed on tailored interventions together with the patient's relatives or caregivers.
 The main outcome variable was changes in the score of the behavioural disorders subscale of the NPIq questionnaire administered by the geriatrician. The consumption of psychotropic drugs, standardised by defined daily doses (DDD) according to WHO, was also analysed.
 Results: 81 persons were included (72% women), mean age 89.5 years. Seventy percent lived in a private home and the remainder in care homes. At baseline, they had the following mean (SD) symptom intensity scores of: delirium 1.1 (2.7), hallucinations 1.3 (2.6), agitation-aggression 2.6 (4.3), depression 0.9 (2.9), anxiety 1.1 (3.0), euphoria-denial 0.1 (1.0), apathy 0.6 (2.3), disinhibition 0.3 (1.7), irritability 1.0 (2.7), motor disturbances 0.9 (2.7), nocturnal behaviours 2.2 (3.8), appetite-ingestion 0.3 (1.6), total intensity 12.5 (13.7). At baseline, 42.0% were taking benzodiazepines, mean DDD 19.9/100 patients. 
 After the intervention there was an average decrease of -7.6 points in the total NPIq scale (95%CI -10.0 to -5.1; p<0.001) and 50% of those taking benzodiazepines had discontinuation or dose decrease. without significant changes in other psychotropic drugs (only an increase in donepezil and memantine).
 Learnings: The integrated management program of elderly with dementia and behavioural disorders improved behavioural symptoms with decreased doses of BZD after the intervention.
 Next Steps: For scientific purposes, to perform a randomised controlled clinical trial. For local managerial purposes, to scale up the initiative to all eligible persons.

Clinical blood test interpretation. Part 1. Neutrophil granulocytes

INRODUCTION. Recent decades are characterized by a rapid introduction of modern automated analytical systems in clinical laboratory diagnostics such as hematology analyzers, which provide a high accuracy of results as well as additional (compared to routine tests) and often more valuable information. Automated blood test has made urgent the problem of interpreting both new tests and “routine” parameters that is relevant to any section of clinical medicine. Therefore, this lecture is aimed at doctors of different specialties.
 OBJECTIVE. Interpret a clinical blood test.
 DISCUSSION. It is hard to review all aspects of hematological analysis within the scope of one lecture, thus part 1 will investigate one of leukocyte populations – neutrophil granulocytes, which include stab and segmented neutrophils. The lecture presents well-known data about neutrophilic leukocytosis and neutropenia. The emphasis is placed on new parameters of automated blood test – IG (immature granulocytes), Neut-RI (reactivity index), Neut-GI (granularity index), MNV (the average volume of neutrophil), structurally dispersed characteristics (NE-WX, NE-SFL, NE-WZ) and some others. Along with modern parameters it was noted the importance of the traditional cytological examination of blood smear, enabling to detect anomalies of neutrophil (degenerative-dystrophic changes of cytoplasm, apoptosis, nucleus pathology).
 Overall, recent years have shown a significant improvement in laboratory diagnostic capabilities of reactive changes (with inflammation, injury, etc.) and blood diseases (anemia, myelodysplastic syndromes, hemoblastosis, etc.), based on accumulated knowledge in the field of laboratory hematology, including clinical significance in evaluating neutrophils.

Investigating Chronotype and Sleep Quality in Psoriatic Patients: Results from an Observational, Web-Based Survey.

Psoriasis is an inflammatory disease for which the implications and repercussions go far beyond the skin. Psoriasis patients suffer not only due to its skin manifestations and related symptoms but also because of comorbidities and a huge emotional impact. The objective of this study was to investigate chronotype and sleep quality in a group of Italian psoriatic patients. An observational, cross-sectional, web-based study was set up by the Dermatology and Clinical Medicine Sections of the Department of Medical Sciences, University of Ferrara, Italy. The web questionnaire was sent to an email list of an Italian association of psoriatic patients with the aim of recording their main demographic, social, historical, and clinical data. The survey included two questionnaires: the Morningness-Eveningness Questionnaire (MEQ) and the Pittsburg Sleep Quality Index (PSQI). Two hundred and forty-three psoriatic patients (mean age 52.9 ± 12.8 yrs., 32.5% males and 67.5% females) filled out the questionnaire. A good 63.8% of them were affected with psoriasis for more than 10 years, 25.9% reported having a diffuse psoriasis, and 66.7% were on treatment at the time they completed the questionnaire. With reference to chronotype, the mean MEQ score was 55.2 ± 10.7; furthermore, 44% of the patients were "morning-oriented types", M-types, or "larks", 44.5% were "intermediate-types" or I-types, and 11.5% were "evening-oriented types", E-types, or "owls". No correlations were found between chronotype and psoriasis extension. Based on the PSQI results, 72.8% of the study population was judged to have a low sleep quality. Sleep disturbance was significantly related to female sex, living alone, and the presence of comorbidities. Sleep disturbance is very common in psoriatic patients, especially in those with comorbidities, in females, and in patients who live alone. The chronotype in psoriatic patients does not appear different when compared to the general population, nor does it seem to have any link with psoriasis severity.

Morphological structure of the right ventricular outflow tract (RVOT) muscle including anatomical variations - clinical implications for electrocardiological procedures using autopsy material

Abstract Background/Introduction The therapeutic effect of the electrocardiological procedure results not only from the correct supply of rhythm or conduction disturbances, but also from the avoidance of complications. The optimisation of the procedure is furthermore related to the efficient reaching of the target site and avoiding blockage of the used equipment by myocardial bridges or trabeculations. Purpose The purpose of our study was to evaluate in detail the right ventricular outflow tract (RVOT) muscle and to determine the types and extent of variation in this area. Methods We analysed 220 hearts (82 female, 37.2%) obtained during forensic medicine section from adult donors without structural heart disease. Collected hearts were fixed in 10% formaldehyde solution. The RVOT was opened by dissecting the muscle along its right periphery. The researchers assessed the presence and position of myocardial bridges, myocardial recesses and trabeculations. In addition, wall thickness and the presence of epicardial fat were assessed at 3 levels along the long axis of the RVOT at 4 points at each level. Linear dimensions were recorded using a precision electronic calliper by 2 different investigators. Statistical analyses were performed using STATISTICA 13.1. Results The presence of myocardial trabeculations covering the entire RVOT free wall was found in 72 hearts (35.5%), with 12 (5.90%) having a completely smooth wall. In the remaining 119 (58.6%), myocardial trabeculations covering the free wall partially were found. In the transition of the free wall to the posterior wall, trabeculations were found on the right and left periphery in 44 (21.6%) and 72 (35.6%) cases, respectively. At the same time, trabeculations were found in the middle part of the posterior wall in only 2 cases (1%). The RVOT recesses were found in 190 cases (92.2%), their number ranging from 1 and 6, with 3 being the most frequently found (26.7%). They were most frequently described on the left and right periphery (in 62.4%, 59.9% of hearts, respectively). Muscle bridges, running through the RVOT lumen, were localised within the left periphery in 109 cases (40.1%). RVOT muscle thickness ranged from 10.5 mm [5.24 mm] (median [IQR]) on the posterior wall, in the middle level, to 4.00 mm [1.36 mm] (mean [SD]), proximally, on the left periphery of the RVOT. The occurrence of epicardial adipose tissue ranged from 196 (96.1%) on the right periphery, in the middle part of the RVOT, to 102 [54.5%] proximally, on the anterior periphery. Conclusions The presence of myocardial bridges and RVOT recesses, while varying in their location and size, are factors that make full access difficult. The small thickness of the RVOT free wall in different regions suggests to consider wall perforation as a probable complication of the procedure, and the concomitant epicardial adipose tissue may be a factor explaining the subacute course of complications, including cardiac tamponade.

Fundamentals of designing high-quality surveys: revisiting neonatal perinatal medicine survey applications.

Surveys in neonatal perinatal medicine are practical instruments for gathering information about medical practices, and outcomes related to the care of newborns and infants. This includes research for identifying needs, assessing requirements, analyzing the effects of change, creating policies, and developing curriculum initiatives. Surveys also provide useful data for enhancing the provision of healthcare services, assessing medical specialties, and evaluating training programs. However, creating a high-quality survey can be difficult for many practitioners, particularly when deciding how to formulate the right questions, whether to utilize various types of questions and how best to arrange or format the survey tool for effective responses. Problems with design principles have been evident in many surveys submitted for dissemination to the members of the Section of Neonatal Perinatal Medicine (SoNPM). To prevent potential measurement errors and increase the quality of surveys, it is crucial to follow a systematic approach in developing surveys by adhering to the principles of effective survey design. This review article provides a brief summary of survey use within the SoNPM, and offers guidance for creating high-quality surveys, including identifying important factors to consider in survey development and characteristics of well-written and effective questions. We briefly note techniques that optimize survey design for distribution through digital media.

Monitoring and management of hypertriglyceridemia in extremely low birth weight neonates receiving intravenous lipid emulsions: A national survey

AimTo assess the practice variation of defining, monitoring and managing hypertriglyceridemia (HTG) in extremely low birth weight neonates receiving intravenous lipid emulsions (IVLE). MethodsAn 8-question survey created via the web survey site Qualtrics was distributed to neonatologists, neonatal nurse practitioners and fellows within the Section of Neonatal-Perinatal Medicine email directory list in the United States and Canada. Survey results were obtained between August and September 2022. ResultsThere were 249 respondents from approximately 4000 members within the Section of Neonatal-Perinatal Medicine. Responses were documented as a frequency (percentage) with a margin of error of plus or minus 6.2 %. Most respondents were neonatologists, individuals practicing for >10 years and reported a unit-based policy for IVLE initiation and advancement. The definitions of HTG varied among respondents, with the majority (42.7 %) reporting a defining threshold of >200 mg/dL. Nineteen percent of respondents reported not routinely monitoring serum triglyceride concentrations with variable triglyceride monitoring intervals reported by other survey respondents. Regarding elevated triglyceride concentrations, 19.0 % reported decreasing the IVLE rate and checking triglyceride concentrations until normalization; 14.6 % reported IVLE discontinuation and monitoring triglyceride concentrations until normalization; 61.9 % reported using a combination of the above practices; and 4.4 % reported individualized practices for IVLE management with elevated triglyceride concentrations. ConclusionThis survey demonstrates a high variation in defining, monitoring and managing HTG in extremely low birth weight neonates and emphasizes the need for studies to better guide this practice.

0508 Adherence with Transoral Neuromuscular Electrical Stimulation Therapy in Veterans with Mild OSA

Abstract Introduction Mild obstructive sleep apnea (OSA) is increasingly common in the VA. The first-line therapies are medical devices worn each night while asleep to control or manage OSA. These devices are burdensome for our patients with mild OSA. Stronger oral musculature can help reduce mild OSA. A new transoral Neuromuscular Electrical Stimulation (NMES) device was recently approved by the US FDA called eXciteOSA (Signifier Medical Technologies, Needham, MA). The eXciteOSA device provides gentle, low-frequency electrical stimulation intraorally to the tongue muscle and is efficacious for mild OSA. Methods A retrospective review of the data of the 71 patients prescribed the eXciteOSA device at the VA San Diego was analyzed. The device is prescribed for use over two phases: (1) one 20-minute session per day over 42 consecutive days and then (2) one 20-minute session on two days out of each week. Respiratory therapists performed 1-2 phone call visits to assess symptoms and address device concerns. Results 68 of the 71 patients used the device for at least one 20-minute session over the first 42 days. Three patients (4.2%) did not use the device. Adherence was 60% for all 71 patients and 63% for the 68 patients who used it at least once. This means that, on average, our Veteran patients completed one 20-minute session on 25 of the first 42 days. Conclusion Recent non-Veteran data showed an adherence rate of ~80% (percentage of days with one completed 20-minute session over the first 42 days). Our analysis found an adherence rate of ~60%, suggesting significant room for improvement in eXciteOSA device use in Veterans. Future adherence studies should look at methods to improve device use over the first 42 days. In addition, more research may be needed to understand better what amount of use is efficacious on an individual basis. Some patients may obtain an adequate response with fewer sessions, while others may need more. It is unknown which endotypes of OSA most benefit from NMES, but further research is ongoing.

0568 Trends in OSA Disease Severity Over Nearly Two Decades: Update on the VA San Diego Experience

Abstract Introduction The Veterans Health Administration (VA) is one of the largest integrated healthcare systems in the United States. Key risk factors for obstructive sleep apnea (OSA) include aging, weight, and male gender, all of which are highly prevalent in the VA population and help to explain the higher rates of OSA in the VA. The Pulmonary Sleep Program at the VA San Diego Healthcare System (VASDHS) started a patient database over twenty years ago for its home sleep apnea testing (HSAT) program. An analysis of ten years of diagnostic HSAT data was reported on over 12,500 patients in 2014. This analysis focuses on an update on the last four years and a comparison to 2014. Methods A retrospective review of the local clinical database of HSAT diagnostic testing was conducted. The database contained 8,928 sleep studies from 2018 to 2022. Invalid studies were removed. Only initial diagnostic studies were included. Results Of the 8,928 diagnostic studies, 2,564 tested negative for OSA (28.7%). Of the 6,364 positive cases, 43.3% were mild, 28.8% were moderate, and 27.9% were severe. The percentages of each OSA severity level were stable across these years (mild: 42%-45%; moderate: 27%-32%; and severe: 26%-29%). The mean AHI did not significantly change from 2018 (24.1+/-20.6) to 2022 (25.1+/-21.2) (overall mean 24.4+/-20.3; range: 5-140). Conclusion Based on this extensive retrospective review of diagnostic testing at a single, high-volume HSAT program, it appears that OSA severity levels have stabilized over these past five years, with the highest percentage of mild OSA cases (~43%) followed by moderate (~29%) and severe (~28%). Our facility saw a significant decrease in severe cases (60% to 30%) and increase in mild OSA (7% to 35%) from 2004 to 2013. Today, over 4 out of every 10 new OSA diagnoses are mild, which has significant treatment implications given that adherence to the two primary medical device options is suboptimal. Identifying patient-centered treatment options for these patients is a priority.

Evaluation of Position of Mental Foramen in Dentulous Population by Digital Panoramic Radiography.

The mental branch of the trigeminal nerve, which supplies sensation to the lower lip, originates in the mandibular canal, making it an essential anatomical structure for dentists and oral surgeons to access. It is not well known that there is a spectrum of normal that includes variants in which there may be more than one nerve entry site, which means that if the mental foramen is not protected, normal feeling in the lower lip may be lost permanently. The diagnostic value of global radiographic landmarks like the mandibular trench and the dental foramen in identifying skeletal problems has been investigated. Four hundred patients over 40 who fit the inclusion/exclusion criteria were chosen. Patients were recruited from Vananchal Dental College and Hospital, Garhwa's Out Patient section for Oral Medicine, Diagnosis, and Radiology. The following patients with their consent are subjected for digital orthopantomography (Cephalometric Device for Rotograph EVOD Ref 930790001, SN 14112930, Villa Sistem Medical) and the captured images are then interpreted for the variations in mandibular canal. The results of our study are as follows: In this study, the mean age of the subjects was 47.27 years, with a range of 40-75 yearsMajority of cases were females (53.75%) and 46.25% were males.The top of the residual ridge, located between the mental foramen and the mandibular canal, is clearly visible to all observers (grade I).Only 1.75% of the people surveyed had a bifid canal, despite the fact that the majority of the people surveyed had a single mandibular canal on both sides (98.25%).Right side mean was 18,682.017, whereas left side mean was 16,331.851; nevertheless, this difference was not statistically significant (P = 0.0860 NS). The dental foramen was located close to where the mandible and the area housing the next premolar met. These findings may be utilized to improve the safety of peri-apical surgical procedures. Therefore, it is therapeutically relevant to get insight into the structural alterations of the mental foramen and locate its location in preoperative radiological scans.
