Lived Experiences of Patients After Colorectal Cancer and Permanent Colostomy: A Parallel-Design Mixed-Methods Study.

To identify the lived experiences, quality of life (QoL), and level of ostomy adjustment (OA) in patients after colorectal cancer with a permanent colostomy (PC). In this parallel-design mixed-methods study, the researchers interviewed 14 patients after colorectal cancer whose PC was created more than 1 year prior. Qualitative data were interpreted using hermeneutic interpretive phenomenological design. Quantitative data were collected with the Stoma QoL Scale and OA Inventory-23. The mean age of the participants was 61.5 (SD, 10.0) years, and the mean PC duration was 7.7 (SD, 5.0) years. Mean QoL and OA scores were just above the median. Three superordinate themes consisting of nine themes emerged from the analysis: (1) early experiences (acceptance, medical problems, and emotional changes); (2) long-term experiences (physiologic experiences, psychosocial experiences, economic experiences, and coping strategies); (3) feelings and expectations about the future (worries and expectations). Even individuals who have been living with a PC for a long time may not be fully adapted to the process and may not have internalized lifestyle changes. Nurses should provide support to individuals with a PC through routine follow-ups, social support, and facilitative healthcare strategies regardless of the length of time since PC creation.

Psychological correlates of obesity

Obesity is not only a medical problem, but also a psychological one. People with obesity often experience stigma, discrimination, and prejudice, which can lead to low self-esteem, depression, and anxiety. In addition, unhealthy eating habits are often linked to emotions such as stress, sadness, or boredom, which can lead to eating to excess. For this reason, understanding the psychological aspects of obesity is important for effective intervention in this area. Many factors influence the development of obesity, including genetic, hormonal, environmental, and behavioral factors. One of the most important factors is lifestyle, particularly eating habits. People with obesity are often characterized by unhealthy eating habits, such as high-calorie and processed foods, lack of meal regularity, and excessive consumption of sweets and sweetened beverages. This article focuses on the relationship between psychological factors and eating behavior in people with obesity. Gathering this information is important for understanding what factors may influence the development and persistence of obesity and what psycho-dietetic strategies may be effective in changing eating habits and reducing weight.

Bioethical, medical, and social problems in children with growth hormone deficiency

Background. Medical and practical advancements have brought about new possibilities for providing healthcare to people, but with it comes new bioethical challenges. In many pediatric medical institutions, consultations on pediatric ethics have become common practice. However, the bioethical problems related to short children have not been studied enough yet. The purpose of this study is to identify and analyze bioethical, medical, and social issues in children with growth hormone deficiency (GHD), which can potentially hinder timely diagnosis and adherence to replacement therapy. Materials and methods. The identification of bioethical, medical, and social problems was conducted at the Odesa Regional Children’s Hospital between 2012 and 2020. The study involved a cohort of 94 children with GHD and short stature (SDS 3.4 ± 0.1), aged 7.2 ± 0.4 years, as well as their parents (124 individuals). The study was based on a questionnaire survey, history taking, interviews, objective examination of patients, and analysis of medical records. Results. The study found evidence of violations of the Hippocratic principle of help and assistance (“do good”) in the form of delayed or incorrect diagnosis in 10.6 % of cases and incomplete adherence to local protocols for managing sick children in 6.4 % of cases. Violations of the Hippocratic principle of non-harm (“first, do no harm”) were evidenced by adverse events (16.0 %) and serious adverse events (3.2 %) during replacement therapy. Children with GHD were subject to violations of social justice, such as neglect (8.5 %), socio-economic problems in the family (12.8 %), and external environmental restrictions (9.6 %). Violations of the personal autonomy of children with GНD inclu­ded physical and psychological abuse in the family (29.8 and 38.3 % of cases, respectively), stigmatization (25.5 %), school bullying (27.2 %), medical neglect (5.3 %), medical paternalism (6.4 %), and overprotection (10.6 %). Conclusions. In the management of children with GHD, various bioethical, medical, and social issues have come to light. Low adherence to recombinant human growth hormone therapy can be considered an independent bioethical problem associated with medical paternalism and medical neglect.

The use of Hermite wavelet collocation method for fractional cancer dynamical system

Tumour is a very serious and dangerous health risk, which is defined as a mass or lump of tissue formalized by the aggregation of abnormal cells. In this paper, we have presented a comparative and chaotic investigation of tumour and effector cells using non-integer order tumour immune dynamical model. Also, we have looked at the interactions between different tumour cell populations and immunological composition using a model of a real-world medical research problem. Additionally, stability analysis of the proposed model is established with the help of fixed-point iteration. Further bifurcation diagrams, as well as phase portraits, have been used to study the proposed system numerically and to analyse its behaviour. For numerical simulations, we have used the Hermite wavelet operational matrix and Taufik-Atangana methods using Caputo fractional derivatives. models. The main objective of the paper is to convert nonlinear fractional systems into algebraic equations. Our findings will be valuable to biologists in cancer treatment.

Revision of restrictive bariatric procedures in elderly patients: results at a 5-year follow-up.

Revisional Bariatric Surgery (RBS) is increasing in popularity. Elderly patients (> 65 years old) are sometimes referred for RBS evaluation. The aim of this study is to evaluate outcomes of elderly patients undergoing RBS. A retrospective analysis of a cohort from a single-tertiary bariatric center. All elderly patients undergoing RBS after restrictive procedures between 2012 and 2022 were included. Thirty Nine patients undergoing RBS were included in the comparative analysis -23 patients (57.5%) after adjustable gastric banding (s/p LAGB) and 16 patients (40%) after Sleeve Gastrectomy (s/p SG). The mean age and body mass index (BMI) of patients were comparable (67.2 ± 2.8 years and 38.3 ± 7.4, respectively). There was no difference in associated medical problems except reflux which was higher in s/p SG (68% vs. 13%; p < 0.001). The mean time interval between surgeries was 8.7 ± 5.1 years. The surgeries included One anastomosis gastric bypass (n = 22), SG (n = 8) and Roux-en-y gastric bypass (n = 9). Early major complication rates were comparable (4.3% and 12.5%; p = 0.36), and readmission rate was higher in patients s/p SG (p = 0.03). Ninety percent of patients were available to a follow-up of 59.8 months. The mean BMI and total weight loss was 29.2 and 20.3%, respectively with no difference between groups. The rate of patients with associated medical problems at last follow-up was significantly reduced. Five patients (12.5%) underwent revisional surgery due to complications during follow-up. In conclusion,RBS in the elderly is associated with a reasonable complication rate and is effective in terms of weight loss and improvement of associated medical problems in a 5-year follow-up.

Pediatrics, Pediatricians and Child Care : Based on 16th Dr. K. C. Chaudhuri and Dr. Amala Chaudhuri Oration, on 15th October 2023.

Medical problems of children and their differences from adults have been mentioned in the ancient texts. Important contributions to medicine, including treatment of diseases of children were made by Greek and many scholars from middle East countries in 10th century. Pediatrics became widely recognized in Europe and USA during early 19th century and a number of children's hospitals were established in major cities. With technological advances, pediatric subspecialties also developed. In India, pediatrics was recognized around 1950s and thereafter, gradually progressed. Pediatric specialties came up in 1970s and became well established during 2020s.Pediatricians are regarded as doctors treating sick children. Pediatric specialists have the responsibility of providing tertiary care to patients with complex systemic diseases and critical care. In our country having a huge underprivileged population, pediatricians need to play a wider role and aim to provide comprehensive care that would lead to optimum development for every child. They should be aware of child rights, widely prevalent child abuse and exploitation and legal protective mechanisms, and attempt to tackle these issues in association with other agencies and organizations working for child welfare.

Being a Doctor: From Treating Individual Patients to Maximising Community Health and Social Justice.

This study examined variation in medical practitioners' practice-based conceptions of what it means to be a doctor, based on interviews with 30 clinicians who were also medical educators. Participants included general practitioners, surgeons and physicians (non-surgical specialists). Participants were asked to draw a concept map of 'being a doctor', followed by semi-structured interviews using a phenomenographic research design. Three conceptions were identified, varyingly focused on (1) treating patients' medical problems; (2) maximising patients' well-being; and (3) maximising community health. Each conception was distinguished by variation in awareness of six underlying dimensions of being a doctor: (1) doctors' actions; (2) treatment success; (3) patients' actions; (4) patients' well-being; (5) community needs; and (6) social justice. Whilst all participants included dimensions 1 and 2 in their described practice, numerous participants did not include dimensions 3 and 4, i.e. did not take the patients' role and the impact of patients' psychosocial context into account in their practice. This is concerning, especially amongst medical educators, given the widely acknowledged importance of patient-centred care in medical practice. Similarly, only some of the participants considered community health needs and felt a broader social responsibility beyond their responsibility to individual patients. These findings highlight aspects of the medical profession that need to be further emphasised in medical training and continuing professional development.

Long-term consequences of COVID-19 in hospitalized patients over 75 years old

BACKGROUND: The COVID-19 pandemic remains an urgent medical and socio-economic problem. The symptoms, signs and complications of COVID-19 in the acute phase of the disease are now well known, while the long-term consequences of the disease continue to be studied. AIM: The aim of this study was to study the frequency, clinical manifestations of “prolonged” COVID-19 and post-covid syndrome in advanced and old ages people treated in a hospital. MATERIALS AND METHODS: The study included patients aged over 75 years old diagnosed with COVID-19 who were treated in two multidisciplinary hospitals in Moscow in 2021–2022: 94 patients aged 75 to 94 years, including 75.5% of women. At the stage of inpatient treatment, patients were interviewed and medical records were analyzed with registration of demographic data, comorbidities, clinical symptoms and signs of the disease, laboratory markers, complications, and treatment outcome. After 1 and 12 months. after discharge, among the survivors, they were interviewed by telephone interview using a special questionnaire with registration of complaints, repeated hospitalizations and complications of COVID-19, assessment of their psycho-emotional state and identification of cognitive-behavioral disorders. RESULTS: In 70.2% of cases, the disease proceeded in a severe and extremely severe form. The majority of patients before COVID-19 had chronic diseases, most often arterial hypertension (85.9%), chronic heart failure (45.7%) and diabetes mellitus (27.2%). Hospital mortality was 22.6%. Poll after 1 month performed in 41/70 surviving patients (58.6%). Among the symptoms, the most common were fainting (41.5%), palpitations (36.6%), constipation (34.1%), the appearance or increase of shortness of breath (31.7%). Almost every day, 14.6%, 12.2% and 14.6% of the respondents experienced stress, anxiety and apathy. Difficulties in performing hygiene procedures, self-care, dressing were observed in 19.5, 12.2 and 12.2% of cases, respectively; 36.6% experienced severe problems when walking long distances. Poll after 12 months performed in 34/70 people (51.4%). Among the symptoms, the most frequently recorded were behavioral changes (32.4%), increased blood pressure (26.5%), problems with vision (26.5%) and hearing (23.5%). Psycho-emotional disorders were detected less frequently: 2 patients (5.9%) experienced daily stress, 1 respondent (2.9%) was worried about strong agitation and apathy. Difficulties in dressing, performing hygiene procedures, self-care were experienced by 32.4, 29.4 and 8.8% of patients; 20.6% experienced severe problems when walking long distances. CONCLUSIONS: The conducted study indicates a high prevalence of symptoms of “prolonged” COVID-19 and post-covid syndrome in elderly people and the duration of their persistence, which may limit their functional activity and negatively affect the quality of life.

Ongoing decision-making dilemma for treatment of de novo spinal infections: a comparison of the Spinal Infection Treatment Evaluation Score with the Spinal Instability Spondylodiscitis Score and Spine Instability Neoplastic Score.

De novo spinal infections are an increasing medical problem. The decision-making for surgical or nonsurgical treatment for de novo spinal infections is often a non-evidence-based process and commonly a case-by-case decision by single physicians. A scoring system based on the latest evidence might help improve the decision-making process compared with other purely radiology-based scoring systems or the judgment of a single senior physician. Patients older than 18 years with an infection of the spine who underwent nonsurgical or surgical treatment between 2019 and 2021 were identified. Clinical data for neurological status, pain, and existing comorbidities were gathered and transferred to an anonymous spreadsheet. Patients without an MR image and a CT scan of the affected spine region were excluded from the investigation. A multidisciplinary expert panel used the Spine Instability Neoplastic Score (SINS), Spinal Instability Spondylodiscitis Score (SISS), and Spinal Infection Treatment Evaluation Score (SITE Score), previously developed by the authors' group, on every clinical case. Each physician of the expert panel gave an individual treatment recommendation for surgical or nonsurgical treatment for each patient. Treatment recommendations formed the expert panel opinion, which was used to calculate predictive validities for each score. A total of 263 patients with spinal infections were identified. After the exclusion of doubled patients, patients without de novo infections, or those without CT and MRI scans, 123 patients remained for the investigation. Overall, 70.70% of patients were treated surgically and 29.30% were treated nonoperatively. Intraclass correlation coefficients (ICCs) for the SITE Score, SINS, and SISS were 0.94 (95% CI 0.91-0.95, p < 0.01), 0.65 (95% CI 0.91-0.83, p < 0.01), and 0.80 (95% CI 0.91-0.89, p < 0.01). In comparison with the expert panel decision, the SITE Score reached a sensitivity of 96.97% and a specificity of 81.90% for all included patients. For potentially unstable and unstable lesions, the SISS and the SINS yielded sensitivities of 84.42% and 64.07%, respectively, and specificities of 31.16% and 56.52%, respectively. The SITE Score showed higher overall sensitivity with 97.53% and a higher specificity for patients with epidural abscesses (75.00%) compared with potentially unstable and unstable lesions for the SINS and the SISS. The SITE Score showed a significantly higher agreement for the definitive treatment decision regarding the expert panel decision, compared with the decision by a single physician for patients with spondylodiscitis, discitis, or spinal osteomyelitis. The SITE Score shows high sensitivity and specificity regarding the treatment recommendation by a multidisciplinary expert panel. The SITE Score shows higher predictive validity compared with radiology-based scoring systems or a single physician and demonstrates a high validity for patients with epidural abscesses.

IMPROVE THE EFFECTIVENESS OF PREDICTIVE MODELS FOR LENGTH OF HOSPITAL STAY (LOS) BY ADDING ELECTRONIC HEALTH RECORDS DATA: A RETROSPECTIVE STUDY IN PATIENTS WITH HEART FAILURE

Abstract Background Length of hospital stay (LOS) is considered a key process that has a clinical, economic, and organizational impact representative of the quality of care. In particular, in patients with heart failure (HF), which is a life–threatening multifactorial syndrome and a major public health problem, when a prolonged LOS (PLOS) occurs, frequent readmission and high mortality are common, with worrying consequences for health systems. Although the LOS is often explained by standard medical data (e.g., comorbidities), it may depend on many other patient characteristics. Therefore, considering additional elements collected in electronic health records (EHRs) could be crucial to predict the occurrence of a LOS and correctly estimating this risk. The aim of this study is to demonstrate the predictive power of clinical and organizational data collected through an EHR on LOS in HF patients. Methods A descriptive, retrospective study was conducted in an Italian university hospital. Data related to HF inpatients consecutively admitted across 1 year were collected from the hospital’s HER. PLOS was defined as a stay ≥ 14 days. Sociodemographic data, administrative data, and clinical data (such as the number of active medical problems, the number of medications, frailty, and nursing dependency), were tested in a predictive model as potential determinants of LOS. Results A total of 608 HF patients were included. The mean age of patients was 76 ± 13.06 years (range: 23–102); 61.5% were male. Prolonged LOS was found in 25.2% of patients. The univariable linear regression model explained 10.2% of LOS variance. Being female, living without social support, having an increased number of previous admissions and nursing dependency, being dependent on functional status, having a worse behavior pattern and mobility, and experiencing a sensory deficit were significant determinants (p &amp;lt; .05) of LOS. Conclusion The inclusion of EHRs data in addition to clinical variables, can help clinicians and researchers to improve the predictive ability on LOS, ensuring its early identification and ultimately enhancing the patients’ health outcomes through the implementation of targeted interventions.

Age-related and species-specific methylation changes in the protein-coding marmoset sperm epigenome.

The sperm epigenome is thought to affect the developmental programming of the resulting embryo, influencing health and disease in later life. Age-related methylation changes in the sperm of old fathers may mediate the increased risks for reproductive and offspring medical problems. The impact of paternal age on sperm methylation has been extensively studied in humans and, to a lesser extent, in rodents and cattle. Here, we performed a comparative analysis of paternal age effects on protein-coding genes in the human and marmoset sperm methylomes. The marmoset has gained growing importance as a non-human primate model of aging and age-related diseases. Using reduced representation bisulfite sequencing, we identified age-related differentially methylated transcription start site (ageTSS) regions in 204 marmoset and 27 human genes. The direction of methylation changes was the opposite, increasing with age in marmosets and decreasing in humans. None of the identified ageTSS was differentially methylated in both species. Although the average methylation levels of all TSS regions were highly correlated between marmosets and humans, with the majority of TSS being hypomethylated in sperm, more than 300 protein-coding genes were endowed with species-specifically (hypo)methylated TSS. Several genes of the glycosphingolipid (GSL) biosynthesis pathway, which plays a role in embryonic stem cell differentiation and regulation of development, were hypomethylated (<5%) in human and fully methylated (>95%) in marmoset sperm. The expression levels and patterns of defined sets of GSL genes differed considerably between human and marmoset pre-implantation embryo stages and blastocyst tissues, respectively.

Complex Pythagorean Normal Interval-Valued Fuzzy Aggregation Operators for Solving Medical Diagnosis Problem

This paper presents a new methodology for solving multiple-attribute decision-making problems (MADMs) using a complex Pythagorean normal interval-valued fuzzy set (CPNIVFS), which is an extended concept of a complex Pythagorean fuzzy set. Four types of different aggregating operations (AOs), including CPNIVF weighted averaging (CPNIVFWA), CPNIVF weighted geometric (CPNIVFWG), generalized CPNIVFWA (CGPNIVFWA), and generalized CPNIVFWG (CGPNIVFWG), are discussed. The scoring function, accuracy function, and operational laws of the CPNIVFS are defined. Algebraic structures, such as associative, distributive, idempotent, bounded, commutativity, and monotonicity properties, are also shown to be satisfied by complex Pythagorean normal interval-valued fuzzy numbers. Furthermore, an algorithm is proposed to solve the MADM problems based on the defined AOs. The proposed approach is then used for a medical diagnosis problem about brain tumors because computer science and machine tool technology are among the most important components of brain tumor research. The five types of brain tumors diagnosed in these patients are gliomas, meningiomas, metastases, embryonal tumors, and ependymomas. Several types of treatments are available, which are often combined as part of an overall treatment plan. Brain tumors can be treated in various ways, including surgery, radiation therapy, chemotherapy, immunotherapy, and clinical trials. Based on the comparisons and options gathered, the most suitable treatment can be chosen. In this regard, it is evident that the value of the integer ⅁\\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\usepackage{upgreek} \\setlength{\\oddsidemargin}{-69pt} \\begin{document}$$\\Game $$\\end{document} plays a significant role in determining the model. The candidate models under consideration can be validated by comparing them with the previously proposed ones. The proposed technique is compared with the existing method to demonstrate its superiority and validity, and the results conclude that the former is more reliable and effective than the latter. Finally, the criteria are evaluated by expert assessments to determine the most appropriate options.

Safety and efficacy of Yaobitong capsules for lumbar disc herniation: A multicenter, randomized, double-blinded, parallel, positive-controlled clinical trial.

Lumbar disc herniation (LDH) is one of the most common diseases and is a global medical and socioeconomic problem characterized by leg or back pain, weakness in the lower extremities and paresthesia. A multicenter, randomized, double-blinded, parallel, positive-controlled clinical trial was conducted to evaluate the efficacy and safety of Yaobitong capsules (YBT) for LDH. Patients (n = 479) were recruited and randomized into YBT and Jingyaokang capsule (JYK) groups (the positive control), and received YBT or JYK at a dose of 3 capsules 3 times per day after a meal for 30 days. The primary efficacy outcome was the Oswestry Disability Index (ODI), with the visual analogue scale (VAS) used as the secondary efficacy outcome. The adverse events and adverse reactions were also evaluated. There was no significant difference in baseline characteristics between YBT (n = 358) and JYK groups (n = 120), and no difference was observed between groups for mean ODI score at day 0 (p = 0.064) or day 7 (p = 0.196), but there were differences at days 14, 21 and 30 (p < 0.001). The YBT showed more decline from baseline, and the decreased ODI score was substantially different from JYK (p < 0.001). The differences in decreased VAS scores between YBT and JYK were also significant at each time point (days 7, 14, 21, and 30), with better scores in the YBT group than in the JYK group (p < 0.001). In terms of safety, there was no obvious disparity in adverse events or adverse reactions between the 2 groups (p > 0.05). Yaobitong was better than JYK for LDH treatment, with no significant difference in safety. The study suggests that YBT is a promising and effective treatment for LDH.

GERIATRIC ASPECTS OF THE ORGANIZATION OF MEDICAL-SOCIAL, PALLIATIVE AND HOSPICE CARE IN THE CONDITIONS OF THE WAR: COMBINATION OF MEDICAL, PSYCHOLOGICAL AND SOCIAL PROBLEMS

The aim of the study is to characterize, from the point of view of geriatric aspects, the current problems of the organization of medico-social, palliative and hospice care (PHC) and social services for palliative care in the war conditions based on multidisciplinary, interagency and inter-sectoral approaches, as well as a combination of medical, psychological and social problems. Materials and methods. The research materials were scientific literary sources and regulatory documents. A pilot survey of 200 people was conducted to study the psychological state and psychological support needs of the elderly and internally displaced persons (IDPs). The survey results of 3,705 client’s questionnaires of the “Vseturbota” Project were also evaluated, of which 63.6 % are people aged 67-84 years, 26.4 % are 85–101 years old. The following research methods were used in the work: bibliosemantic, sociological, system approach and system analysis. Results and discussion. After February 24, 2022, IDPs will experience significant difficulties, suffer from reduced income, increased dependence on humanitarian aid, do not feel safe and protected. All these are reflected in their psychological state. It was found that among respondents aged ≥75 years had the most people with medium (57.1 %) and low (25.0 %) levels of anxiety, 71.4 % had a low level of mood. 32.17 % of the “Vseturbota” Project clients needed additional consultation with a family doctor, 3.83 % needed consultation with a psychologist, and 3.35 % with other specialists. Most often, they needed help around the house (26.02 %), buying medicines/foodstuff (22.43 %), 34.97 % needed information, and 13.36 % needed psychological counseling. An important condition for providing geriatric patients, including IDPs, with affordable, high-quality and effective PHC is the creation of a system and service of ambulatory/mobile and inpatient PHC facilities and medico-social care. Conclusions. The military aggression of the Russian Federation caused considerable suffering to the population of Ukraine. The state of anxiety and fear has a negative impact not only on the psycho-emotional, but also on the physical sphere of the elderly, which necessitates the implementation of psychological services and effective strategies for overcoming stress and distress, which requires the development and implementation of mechanisms for interagency coordination and cooperation, involving and training of multidisciplinary teams’ specialists and volunteers, effective advocacy activities, etc.

Different characteristics but comparable hypertension rates between two MMT “twin” clinics

Background Patients in methadone maintenance treatment (MMT) may develop age-related medical problems. Objective: To compare hypertension prevalence and its risk factors between two MMT clinics, having similar treatment guidelines, but different characteristics, one from Tel Aviv (TA) and one from Las Vegas (LV). Methods Prevalence of hypertension (systolic ≥140 and or diastolic ≥90 mmHg BP) among all current 291 MMT patients in TA and 180 patients in LV were studied, including body mass index (BMI), drugs in urine, sociodemographic, and addiction history data. Results Hypertension prevalence was comparable in TA (35.4%) and LV (34.4%), however TA patients were older (55.9 ± 9.5 vs. 45.5 ± 13.3, p < 0.001), with fewer females (22 vs. 42.2%, p < 0.001), fewer obese (BMI ≥30) (24 vs. 40.9%, p < 0.001), higher cocaine (21 vs. 7.8%, p < 0.001), and lower cannabis (14.1 vs. 32.4%, p < 0.001) and amphetamines (0 vs. 33.5%) users. Logistic regression found higher BMI to characterize hypertension in both clinics, but in TA also negative urine cocaine, benzodiazepine, and opioids screen, while in LV older age (≥50 y), male gender, and negative urine cannabis screen. Conclusions While TA was characterized with older patients, LV patients had a comparable hypertension rate, as obesity was more prevalent. No drug use was accompanied by higher BMI in TA and therefore associated with hypertension. Weight reduction, hypertension detection and treatment are recommended.

High efficacy treatment of murine Pseudomonas aeruginosa catheter-associated urinary tract infections using the c-di-GMP modulating anti-biofilm compound Disperazol in combination with ciprofloxacin.

Persistent urinary tract infections (UTIs) in hospitalized patients constitute an important medical problem. It is estimated that 75% of nosocomial UTIs are associated with urinary tract catheters with P. aeruginosa being a species that forms biofilms on these catheters. These infections are highly resistant to standard-of-care antibiotics, and the effects of the host immune defenses, which allows for development of persistent infections. With antibiotics losing their efficacy, new treatment options against resilient infections, such as catheter-associated urinary tract infections (CAUTIs), are critically needed. Central to our anti-biofilm approach is the manipulation of the c-di-GMP signaling pathway in P. aeruginosa to switch bacteria from the protective biofilm to the unprotected planktonic mode of life. We recently identified a compound (H6-335-P1), that stimulates the c-di-GMP degrading activity of the P. aeruginosa BifA protein which plummets the intracellular c-di-GMP content and induces dispersal of P. aeruginosa biofilm bacteria into the planktonic state. In the present study, we formulated H6-335-P1 as a hydrochloride salt (Disperazol), which is water-soluble and facilitates delivery via injection or oral administration. Disperazol can work as a monotherapy, but we observed a 100-fold improvement in efficacy when treating murine P. aeruginosa CAUTIs with a Disperazol/ciprofloxacin combination. Biologically active Disperazol reached the bladder 30 min after oral administration. Our study provides proof of concept that Disperazol can be used in combination with a relevant antibiotic for effective treatment of CAUTIs.

Prevalence of Chronic Rhinosinusitis in the Jazan Region of Saudi Arabia

Background: Chronic rhinosinusitis (CRS) is one of the most common medical problems worldwide. It has a significant impact on the quality of life and productivity of many people. The prevalence of CRS varies throughout the world. In this study, we evaluated the prevalence of CRS in the Jazan region of Saudi Arabia. Methods: We conducted a cross-sectional study, using an online questionnaire to collect data on demographic, Sinonasal outcome test-22 (SNOT-22), chronic diseases, and smoking status. The prevalence was estimated based on the established diagnosis and a high SNOT-22 score with the presence of three of the cardinal symptoms of CRS. Variables associated with the presence of CRS were evaluated. Results: The 1081 contributors that met our inclusion criteria included 594 males and 487 females with a median (interquartile range) age of 31 (17) years. More than half of all participants (n = 653, 60.4%) had high SNOT-22 (&gt;18/110), but many did not fulfill the criteria for CRS in this study. Of the 1081, 215 had an established diagnosis and had three or more of the cardinal symptoms of CRS. In addition, 134 cases had not been clinically evaluated before but were suffering from three or more of the cardinal symptoms of CRS. Based on this, the estimated prevalence of CRS among our sample was 349 CRS patients (32.3%). CRS was less in people from mountainous areas (24.8%, P = 0.020). Conclusions: CRS was more prevalent in the hotter plains and coasts than in the mountains. Further studies are warranted to estimate the annual incidence and the impact on the health-care services as well as on the occupational and personal lives of the individuals.

Assessment of weaning practices among mothers for their infants attending the Pediatric Outpatient Department of Sindh Government Hospital Paretabad Hyderabad.

General Objective: To assess the weaning practices among mothers for their infants those attending the pediatric outpatient department of Sind Government Hospital, Paretabad, Hyderabad.Specific objectives:1. To determine the age of onset of weaning2. To determine the type of weaning food3. To determine the level of education and its relation to weaningMethods: It was a cross-sectional study conducted at Sind Government Hospital, Paretabad, Hyderabad, duringthe period of 15th May 2008 to 15th June 2008. We had included all the patients according to the inclusion criteriaand did not do sampling. Data was collected by principal investigator herself on a pre-formed, pre – tested questionnaire about weaning practices among mothers for their infants. Respondents were mothers/care givers accompanying their infants who were interviewed in their own language to avoid inconvenience. The operationaldefinitions of variables were already set before the starting of data collection process. The study population included all new patients visiting in out patient department of Sindh Government Hospital Paretabad, Hyderabadduring the study period. The variables included the basic demographic variables i.e. age, residence, occupation,education and socio-economic status of mothers, age of onset of weaning, type of first food given as weaning,hygienic practices of mothers etc.The exclusion criteria included prematurely borne infants, those revisiting OPD, and those who visited the facilityfor acute medical problems that required hospitalization.Result: Among 307 infants aged 3-12 months registered, males were 54.1% in comparison to females (45.9%).The majority of the mothers visiting the facility belonged to slum areas (79.2%). Regarding maternal attitudesand practices of weaning, 67 (21.8%) mothers considered cow’s milk as a weaning diet while majority of them i.e.240 (78.2%) were of the opinion that semisolids were the weaning foods. About 24.8% mothers started weaningearlier and only 47.6% of them started to give weaning food to their infants between ages 3 – 6 months. A strongassociation is evident between socio- economic status of mothers and the use of commercial weaning foods(p=0.01). The study concludes that there is a dire need of promoting among mothers the norms of giving properweaning foods to their infants.

Targeting Prefrontal Cortex Dysfunction in Pain.

The prefrontal cortex (PFC) has justifiably become a significant focus of chronic pain research. Collectively, decades of rodent and human research have provided strong rationale for studying the dysfunction of the PFC as a contributing factor in the development and persistence of chronic pain and as a key supraspinal mechanism for pain-induced comorbidities such as anxiety, depression, and cognitive decline. Chronic pain alters the structure, chemistry, and connectivity of PFC in both humans and rodents. In this review, we broadly summarize the complexities of reported changes within both rodent and human PFC caused by pain and offer insight into potential pharmacological and nonpharmacological approaches for targeting PFC to treat chronic pain and pain-associated comorbidities. SIGNIFICANCE STATEMENT: Chronic pain is a significant unresolved medical problem causing detrimental changes to physiological, psychological, and behavioral aspects of life. Drawbacks of currently approved pain therapeutics include incomplete efficacy and potential for abuse producing a critical need for novel approaches to treat pain and comorbid disorders. This review provides insight into how manipulation of prefrontal cortex circuits could address this unmet need of more efficacious and safer pain therapeutics.

Fibroblast growth factor 21 (FGF21): diagnostic, prognostic and therapeutic aspects in heart failure. A review

Chronic heart failure (CHF) is a global medical, social and economic problem. Currently, the search and study of new biomarkers that can provide early diagnosis of CHF, serve as a laboratory tool for assessing the effectiveness of treatment, or be used as prognostic markers and risk stratification criteria are ongoing. Scientists' interest is focused, in particular, on studying the role of fibroblast growth factor 21 (FGF21) in CHF. There is increasing evidence highlighting the value of FGF21 as a new marker for the diagnosis and assessment of prognosis in patients with CHF. The role of FGF21 in CHF is very interesting due to its cardioprotective aspects. Final confirmation of the diagnostic, prognostic and therapeutic roles of FGF21 will come from future studies.
