Association of Tumor Necrosis Factor-Alpha with Psychopathology in Patients with Schizophrenia.

We investigated the relationship between serum tumor necrosis factor-alpha (TNF-α) levels and psychopathological symptoms, clinical and socio-demographic characteristics and antipsychotic therapy in individuals with schizophrenia. TNF-α levels were measured in 90 patients with schizophrenia and 90 healthy controls matched by age, gender, smoking status, and body mass index. The Positive and Negative Syndrome Scale (PANSS) was used to assess the severity of psychopathology in patients. No significant differences in TNF-α levels were detected between the patients and controls (p=0.736). TNF-α levels were not correlated with total, positive, negative, general, or composite PANSS scores (all p>0.05). A significant negative correlation was observed between TNF-α levels and the PANSS cognitive factor (ρ=-0.222, p=0.035). A hierarchical regression analysis identified the cognitive factor as a significant predictor of the TNF-α level (beta=-0.258, t=-2.257, p=0.027). There were no significant differences in TNF-α levels among patients treated with different types of antipsychotics (p=0.596). TNF-α levels correlated positively with the age of onset (ρ=0.233, p=0.027) and negatively with illness duration (ρ=-0.247, p=0.019) and antipsychotic treatment duration (ρ=-0.256, p=0.015). These results indicate that TNF-α may be involved in cognitive impairment in schizophrenia, and would be a potential clinical-state marker in schizophrenia.

Can laboratory and clinical parameters predict the occurrence of acute arterial occlusion in COVID-19 patients?

Aim To determine radiologic, clinic and laboratory characteristics of COVID-19 positive patients with acute arterial occlusion and compare them with post COVID-19 and non-COVID-19 patients. Methods In this retrospective study, 53 patients with acute occlusion of peripheral arteries admitted to the University Clinical Hospital Mostar in the period between 29 February 2020 and 30 September 2021 were involved. The first group was made of COVID-19 positive patients, the second group were post COVID-19 patients and a control group were non-COVID-19 patients. Results Most patients were males, 37 (69.8%). The average age of COVID positive patients was 66.09±11.25 years, post COVID-19 patients 71.33±5.22 years and COVID-19 negative patients 69.82±1.99 years. Lower extremities were most affected, 38 (71.6%), without significant alteration in the coagulogram. Acute arterial occlusion occurred about 2 weeks after the beginning of COVID-19 or at the time of the first appearance of symptoms. Conclusion We have to take special care about patients with risk factors for developing acute arterial occlusion due to thromboembolism or thrombosis 10 days after the beginning of the disease. We also recommend the use of low molecular weight heparin (LMWH) and monitoring coagulation state due to anti Xa and thromboelastometry.

The Interplay of Cx26, Cx32, Cx37, Cx40, Cx43, Cx45, and Panx1 in Inner-Ear Development of Yotari (dab1-/-) Mice and Humans.

We investigated DAB1-protein deficiency in the inner-ear development of yotari in comparison to humans and wild-type (wt) mice by immunofluorescence for the expression of connexins (Cxs) and the pannexin Panx1. The spatial and temporal dynamics of Cx26, Cx32, Cx37, Cx40, Cx43, Cx45, and Panx1 were determined in the sixth and eighth weeks of human development and at the corresponding mouse embryonic E13.5 and E15.5, in order to examine gap junction intercellular communication (GJIC) and hemichannel formation. The quantification of the area percentage covered by positive signal was performed for the epithelium and mesenchyme of the cochlear and semicircular ducts and is expressed as the mean ± SD. The data were analysed by one-way ANOVA. Almost all of the examined Cxs were significantly decreased in the cochlear and semicircular ducts of yotari compared to wt and humans, except for Cx32, which was significantly higher in yotari. Cx40 dominated in human inner-ear development, while yotari and wt had decreased expression. The Panx1 expression in yotari was significantly lower than that in the wt and human inner ear, except at E13.5 in the mesenchyme of the wt and epithelium and mesenchyme of humans. Our results emphasize the relevance of GJIC during the development of vestibular and cochlear functions, where they can serve as potential therapeutic targets in inner-ear impairments.

Resilience in Health and Illness.

Resilience is a relatively new concept that lacks clarity although it is increasingly used in everyday conversation and across various disciplines. The term was first introduced into psychology and psychiatry from technical sciences and afterwards thorough medicine and healthcare. It represents a complex set of various protective and salutogenic factors and process important for understanding health and illness, and treatment and healing processes. It is defined as a protective factor that makes an individual more resilient to adverse events that lead to positive developmental outcomes. Resilience is a positive adaptation after stressful situations and it represents mechanisms of coping and rising above difficult experiences, i.e., the capacity of a person to successfully adapt to change, resist the negative impact of stressors and avoid occurrence of significant dysfunctions. It represents the ability to return to the previous, so-called "normal" or healthy condition after trauma, accident, tragedy, or illness. In other words, resilience refers to the ability to cope with difficult, stressful and traumatic situations while maintaining or restoring normal functioning. The higher the resilience, the lower the vulnerability and risk of illness. Resilient individuals tend to be optimistic, have a tendency to see everything as a useful experience, focus on personal strengths and qualities, use constructive criticism, develop close relationships with others, have developed social skills, and are emotionally conscious. Good resilience aggravates and prevents the onset of disease, provides good heath, facilitates and accelerates healing, and provides productive life and a sense of well-being despite chronic illness. Resilience experts believe that anyone can strengthen their resilience and thus contribute to the advancement of health and, if ill, ease the illness, accelerate and facilitate healing.

Association of colorectal carcinoma and metabolic syndrome.

Aim Colorectal carcinoma is one of the most common neoplasms, especially in Western countries and those with westernisation. On the other hand, high rate of metabolic syndrome (MetSy) has also been noticed, as well as in Western countries. It seems like these two conditions are somehow connected. In this study, we wish to explore some characteristics of colorectal carcinoma and its correlation with MetSy. Methods In this retrospective study the data were taken from medical records of 67 patients with colorectal carcinoma, and for 30 healthy controls. Input parameters of patients were compared mutually, as well as with parameters of healthy, control examinees that had negative screening colonoscopy for neoplasm. Results Average age of patients was 68 years. The most frequent localisation of neoplasm was on rectum (53.7%) and most frequent level was Dukes C (38.8%). The patients had MetSy more frequently when compared with controls (p=0.048), and also they had more MetSy components (p=0.006). The link between MetSy and localisation of neoplasm was not found, neither with its pathohystological characteristics. Conclusion Patients with MetSy should be warned about the increased risk of colorectal carcinoma, and, in this way, motivated for earlier and more frequent screening colonoscopies, as well as of a change of unhealthy lifestyle.

Anthropometric characteristics and traffic accident circumstances of patients with isolated whiplash injury in University Clinical Hospital Mostar.

Aim To investigate anthropometric characteristics and traffic accident circumstances of subjects with isolated whiplash injury. Methods This cross sectional study involved 75 subjects from traffic accidents with isolated whiplash injury classified by Quebec Task Force (QTF). Anthropometric data were collected as well as claims about circumstances of traffic accidents. Results Distribution of 1st (28; 37.3%), 2nd (25; 33.3%) and 3rd (22; 29.3%) grade of whiplash injury was almost equal. Females had smaller anthropometric measurements than males; neck circumference was the most significant difference between males and females in the context of whiplash injury. The most frequent collision mechanism was impact to front (26; 34.7%) or to rear end (26; 34.7%) of a small passenger's car. Assertions of participants were that their car damage was significant (37; 49.2%) or total (24; 32%). A total of 38 (50.7%) participants claimed that they were not wearing safety belt and 52 (69.3%) did not find themselves responsible for accident. Conclusion Driving habits of our participants facilitate incidence of whiplash injuries, especially in vulnerable groups such as women and elderly.

Isometric muscle fatigue of the paravertebral and upper extremity muscles after whiplash injury.

BACKGROUND: Whiplash-associated disorders (WAD) result from injury of neck structures that most often occur during traffic accidents as a result of rapid acceleration-deceleration. The dominant symptoms manifest in the musculoskeletal system and include increased fatigue. Because of the frequency of whiplash injuries, a simple, cheap and useful diagnostic tool is needed to differentiate whiplash injury from healthy patients or those faking symptoms. OBJECTIVES: To determine muscle fatigue in patients with whiplash injury in six body positions. DESIGN: Analytical cross-sectional study. SETTING: Emergency center, university hospital. PATIENTS AND METHODS: We studied patients with whiplash injury from vehicular traffic accidents who presented to the emergency center within 6 hours of sustaining the injury. We determined whiplash injury grade according to the Quebec Task Force (QTF) classification and measured isometric muscle endurance in six different body positions. Control subjects for each patient were matched by age, gender and anthropomorphic characteristics. Cut-off values were determined to distinguish patients with whiplash injury from controls and for determination of injury grade . MAIN OUTCOME MEASURE(S): QTF grade, time to muscle fatigue in seconds. RESULTS: From September 2013 to September 2016, we enrolled 75 patients with whiplash injury and 75 matching control subjects. In all six positions, the patients with whiplash injury felt muscle fatigue faster than equivalent controls (P < .05) and the time to onset of muscle fatigue decreased with increasing injury grades in all six positions. Assignment to the patient or control group and to injury grade could be predicted with more than 90% accuracy on the basis of time to muscle fatigue. The most efficient position was the highest injury grade, by which 99.9% of the patients were accurately categorized. Isometric muscle endurance correlated with whiplash injury grade in all six positions (P < .01). CONCLUSION: Under clinical conditions, muscle endurance and the appearance of isometric muscle fatigue during testing can be a useful indicator of whiplash injury and grade. LIMITATIONS: The size of the sample was small. An objective parameter such as electromyography is needed to confirm isometric muscle fatigue.

Accuracy of Modified Alvarado Score, Eskelinen Score and Ohmann Score in Diagnosing Acute Appendicitis.

INTRODUCTION: By processing the data of a large number of patients with abdominal pain, diagnostic scores whose implementation attempts to facilitate acute appendicitis diagnostics were developed. Modified Alvarado score, Ohmann score and Eskelinen score are used as assistance when setting the diagnosis and making a decision to undertake surgery. AIM: To assess accuracy of Alvarado score, Ohmann score and Eskelinen score in diagnosing acute appendicitis and to establish connection of total score of these scoring systems with histopathological degree of appendicitis. SUBJECTS AND METHODS: A cross-sectional study was conducted at the Department of Surgery of University Clinical Hospital Mostar. The study included 70 patients who underwent appendectomy and were scored before surgery. All tested persons were examined by experienced surgeon who took anamnesis, physical status and ordered laboratory diagnostic tests. Appendicitis was excluded or confirmed by means of histopathological diagnostics, and the degree of appendicitis was determined. RESULTS: According to accuracy parameters (sensitivity, specificity, negative and positive predictive value), the score which was of highest value was Ohmann score, followed by Eskelinen score, while the lowest value was the one of modified Alvarado score. Total score in all three scoring systems follows the degree of appendicitis, but statistical significance was proven only for Ohmann and Eskelinen scores. CONCLUSION: Ohmann and Eskelinen scores can be useful in diagnosing acute appendicitis, predicting the degree of appendicitis, as well as assistance when making decision to undertake an operative procedure. Modified Alvarado score in our subjects did not prove sufficient value. Diagnostics of acute appendicitis still must be led by contemporary algorithms in which diagnostic scoring is implemented.

Metabolic Syndrome, Total and Differential White Blood Cell Counts in Patients with Schizophrenia.

BACKGROUND: Numerous studies suggest existence of association between total white blood cell (WBC) count and metabolic syndrome (MS) in general population. Aim of this study was to determine the value of total and differential WBC counts and their association with MS in patients suffering from schizophrenia. SUBJECTS AND METHODS: This cross-sectional study included 100 subjects in the study group and 100 healthy subjects in control group. MS diagnosis was made according to ATP III criteria, which was the basis for dividing the study and control group into subgroups with regard to MS diagnosis. From blood samples of all subjects total and differential WBC counts were determined. RESULTS: Schizophrenic subjects with MS had significantly higher total WBC count, as well as neutrophil and monocyte count, when compared with both control subgroups. Total WBC and neutrophil count correlated positively with glucose concentration and MS prevalence and negatively with HDL concentration. CONCLUSION: Total WBC and neutrophil count might have an important role in forecasting MS development in patients with schizophrenia.

Abdominal Wall Endometrioma after Laparoscopic Operation of Uterine Endometriosis.

Endometriosis is presence of functional endometrium outside of uterine cavum. As a pluripotent tissue, endometrium has the possibility of implanting itself almost everywhere; even implantation in abdominal wall was described, but it is not common site. This case report presents implantation of functional endometrium in abdominal wall, inside scar tissue, and after insertion of a laparoscopic trocar port. Final diagnosis was confirmed by pathohistological examination.

Association of erythrocyte sedimentation rate and fibrinogen concentration with metabolic syndrome in schizophrenic patients.

INTRODUCTION: Inflammation can be a process significant to the development of schizophrenia and metabolic disorders that are frequently found in patients suffering from schizophrenia. The aim of this study was to determine the values of erythrocyte sedimentation rate and fibrinogen concentration and to establish their possible association with MS and its components in schizophrenic patients. SUBJECTS AND METHODS: A cross-sectional study was conducted on 200 subjects who were divided into two groups. The study group consisted of schizophrenic patients from the University Clinical Hospital Mostar (n=100), while the control group consisted of healthy subjects who came for systematic medical examinations at the infirmary of the Health Center Mostar (n=100). The diagnosis of MS was made according to NCEP-ATP III criteria, and on that basis subjects from both groups were divided into two subgroups, one with and one without MS. Inflammatory indicators that were determinated were erythrocyte sedimentation rate and fibrinogen concentration. RESULTS: Statistically, MS was significantly more frequent in schizophrenic subjects (46.0%) compared to the control group (29.0%) (p=0.013). Schizophrenic subjects with MS had statistically higher sedimentation rate and fibrinogen concentration compared to the schizophrenic subjects without MS, as well as compared to the control subgroup without MS. The most significant correlations discovered were for the relation of sedimentation rate with systolic (r=0.41) and diastolic (r=0.34) blood pressures. CONCLUSION: Routine monitoring of erythrocyte sedimentation rate and fibrinogen concentration might have an important role in forecasting MS development and consequent adverse cardiovascular events which are the leading cause of mortality in schizophrenic patients.
