A Study of 60 Patients with Low Back Pain to Compare Outcomes Following Magnetotherapy, Ultrasound, Laser, and Electrotherapy with and without Lumbosacral Kinesiotherapy

BACKGROUND This study of 60 patients with low back pain (LBP) aimed to compare outcomes following magnetotherapy, ultrasound therapy, laser therapy, and electrotherapy, with and without lumbosacral kinesiotherapy, and used the Roland-Morris Disability Questionnaire (RMDQ) and the Oswestry Low Back Pain Disability Questionnaire (OLBPDQ). This was a randomized actively controlled intervention trial of adding kinesiotherapy to a standard physiotherapy for LBP. MATERIAL AND METHODS The research included 60 participants with a diagnosis of chronic non-specific lumbar pain syndrome (CNSLPS) (mean±SD age 58.3±15.4 years, 37 women) LBP randomly assigned (1: 1) to 2 treatment groups. In Group 1, 30 patients were treated with magnetotherapy, ultrasound therapy, laser therapy, and electrotherapy. In Group 2, 30 patients received the same treatments as in Group 1, and also performed kinesiotherapy exercises affecting the lumbosacral spine and adjacent muscles. At baseline and at the end of the study, all participants completed the RMDQ and the OLBPDQ. RESULTS Both groups had significant improvement after therapy. Repeated-measures ANOVA indicated that at the end of treatment there was significantly greater progress and symptom reduction (P<0.001) in Group 2. Patients in Group 2 had a pain reduction of 52.5%, while Group 1 had 25.4% pain reduction (P=0.009). CONCLUSIONS For treatment of disability caused by CNSLPS, physical therapy combined with kinesiotherapy should be a treatment of choice.

Use of CPAP Ventilation in Non-ICU Wards May Influence Outcomes in Patients with Severe Respiratory COVID-19

Background and Objectives: The COVID-19 disease has significantly burdened the healthcare system, including all units of severe patient treatment. Non-intensive care units were established to rationalize the capacity within the Intensive Care Unit (ICU) and to create a unit where patients with Acute Respiratory Distress Syndrome (ARDS) could be treated with non-invasive Continuous Positive Air Pressure (CPAP) outside the ICU. This unicentric retrospective study aimed to assess the efficacy of NIV Treatment in Patients of the fourth pandemic wave and how its application affects the frequency and mortality of ICU-treated patients at University Hospital Rijeka compared to earlier waves of the COVID-19 pandemic. Furthermore, the study showcases the effect of the Patient/Nurse ratio (P/N ratio) on overall mortality in the ICU. Materials and Methods: The study was conducted on two groups of patients with respiratory insufficiency in the second and third pandemic waves, treated in the COVID Respiratory Centre (CRC) (153 patients). We also reviewed a cohort of patients from the fourth pandemic wave who were initially hospitalized in a COVID-6 non-intensive unit from 1 October 2021 to 1 November 2022 (102 patients), and some of them escalated to CRC. Results: The introduction of the CPAP non-invasive ventilation method as a means of hypoxic respiratory failure treatment in non-intensive care units has decreased the strain, overall number of admissions, and CRC patient mortality. The overall fourth wave mortality was 29.4%, compared to the 58.2% overall mortality of the second and third waves. Conclusions: As a result, this has decreased CRC patient admissions and, by itself, overall mortality.

Predictors of Quality of Life in Patients with Drug Resistant Epilepsy after Neurosurgical Treatment: One-Year Follow-Up

BACKGROUND

Invasive neurosurgical treatment or minimally invasive neurosurgical treatment are methods of choice for the treatment of patients with drug resistant epilepsy. The aim of this study was to evaluate the impact of neurosurgical treatment and the quality of life of patients with drug resistant epilepsy and to determine what are the potential predictors of quality of life of patients with drug resistant epilepsy one year after neurosurgical treatment.

SUBJECTS AND METHODS

The research was performed at the Referral Centre for Epilepsy, Department of Neurology, University Hospital Centre Zagreb from February 2015 to February 2020 with Ethics commitee approval. The study included 96 patients with drug resistant epilepsy who were examined for the quality of life before and one year after neurosurgical treatment using the form questionnaire "Quality of life in epilepsy" (QOILE-31) validated Croatian 1.0 version and the questionnaire to assess the degree of depression "Beck Depression Inventory I" (BDI-I) validated Croatian version.

RESULTS

Of 96 patients with drug resistant epilepsy one year after neurosurgical treatment 46 (47.9%) patients remained completely free from epileptis seizures. Wilcoxon equivalent pair test showed that the number of epileptic seizures one year after neurosurgical treatment was significantly lower (median before neurosurgical treatment is 10; and after neurosurgical treatment is 1, p<0.001). The most informative potential statistically significant predictor variables of quality of life based on the criterion variables QOLIE-31 and BDI-I are: total disease duration in years (p=0.034), patient age (p=0.042), number of antiepileptics one year after neurosurgical treatment (p=0.001), the number of epileptic seizures per month (p=0.016), and social welfare rights (p=0.045).

CONCLUSION

Neurosurgical treatment of patients with drug resistant epilepsy significantly reduces the number of epileptic seizures which significantly improves their overall quality of life one year after neurosurgical treatment.

Impact of Invasive EEG Monitoring and Resective Neurosurgical Treatment on the Quality of Life in Patients with Drug Resistant Epilepsy - Preliminary Results

BACKGROUND

Neurosurgical treatment is one of important way to cure drug resistant epilepsy. After invasive EEG monitoring and the invasive neurosurgical treatment (resective surgery) there are possible complications (intracranial haemorrhage, cortical lesions and infections), however there are possible neuropsyhologic outcomes such as memory outcomes, language outcomes and psychiatric outcomes. The quality of life in epilepsy (QOLIE-31) scale is a self-completed questionnaire which contains seven subscales which address the following aspects: emotional well-being, social functioning, energy/fatigue, cognitive functioning, seizure worry, medication effects and overall quality of life. Our study aimed to examine the quality of life in patients with drug resistant epilepsy who had undergone invasive EEG monitoring and resective neurosurgical treatment through the application of the QOLIE-31 scale.

SUBJECTS AND METHODS

The study included 9 patients with drug resistant epilepsy who had undergone invasive EEG monitoring followed by resective neurosurgical treatment in the period from 2010 to 2016, and the control group of 15 patients with drug resistant epilepsy who had not undergone neurosurgical procedures. Clinical variables of interest for this study were obtained through phone contact, and the QOLIE-31 scale was applied.

RESULTS

In the domaine of seizure worry, patients in the examined group were more concerned about the seizures (54.7) compared to the examined group (80), as well as in the overal quality of life (examined group 57.5; control group 77.5). Patients in the control group complained more in the domain of antiepileptic therapy (score 70.7) than patients in the examined group (score 100). In the other domains: emotional well-being, energy/fatigue, cognitive functioning, and social functioning there were minor deviations between the examined and control groups.

CONCLUSION

There was no statistically significant difference between individual QOLIE-31 questionnaires, as well as between the two groups of respondents.

Treatment of advanced peripheral arterial insufficiency in the elderly

Peripheral arterial insufficiency appears at all stages regardless of the patient age; however its appearance is most common in the elderly in which cases it mostly appears as stage described by Fontaine as stage III or IV The most com- mon cause of peripheral arterial insufficiency is atherosclerotic degeneration, and is remarkably often accompanied by the diabetes. In the years 2012 and 2013 department of vascular surgery, University Hospital Rijeka admitted 169 patients older than 70 with peripheral arterial insufficiency of type Fontaine III and IV That number represents 68.8% of total number of patients admitted for peripheral arterial insufficiency. The goal of this research is to identify to what extent and in what percentage can patients older than 70 with advanced peripheral arterial insufficiency be subjected to vascular treatment and if there exist and absolute indication for angiographic treatment of such patients. In majority of patients, 148 of them, three or more comorbidities were present. Diabetes was present at almost half of patients, to be exact 46.7%. Assessment of possibility for vascular treatment and the need for angiographic treatment was followed in patients in three age groups: 70-75 years of age, 76-80 years of age and over 80 years of age. Angiography was performed on 69 patients and the insight into angiographic finding resulted in only 33 patients being subjected to some type of vascular treatment. From the total number of patient's subjected to vascular treatment 20 had symptoms of Fontaine III while the remaining 13 had symptoms of Fontaine IV Amputation procedure was performed 119 times. The research shows that angiograph- ic treatment is not a routine treatment in mentioned patients and that the number of vascular procedures is significantly higher in the 70-75 years age group.

Craniofacial morphologic and anthropometric features of Croatian schizophrenia patients and non-psychiatric controls--a pilot study

AIM

to evaluate differences in craniofacial morphologic features and several anthropometric measures between schizophrenia patients and non-psychiatric controls, and to find the best-fit model to differentiate between two groups.

METHODS

40 morphologic features of the head and face, and 5 craniofacial anthropometric measures were evaluated using the Lane Dysmorphology Scale in 58 patients and 46 controls. Total MPA score and subscores for different craniofacial regions were calculated. Individual items were examined using logistic regression analyses to define a model that can discriminate between patient vs. control status.

RESULTS

total MPA score, and several subscores (general asymmetry, nasal, lip, ear and tongue) were significantly higher in the patient group. Patients were distinguished by significantly higher measures of maxillary and mandibular facial arcs, general and subtle facial asymmetries presented as deviation of facial landmarks from the vertical facial midline and horizontals, more variable vermilion of the upper lip, tongue surface, frenulum and anterior hair margin, and more adherent and underdeveloped earlobes. A final regression model including maxillary are, facial asymmetry, and adherent earlobes as independent predictors proved useful to efficiently recognize schizophrenia patients (specificity and positive prediction value of 100% when all the three items were present in an individual) or to exclude risk for schizophrenia (sensitivity and negative prediction value of 96.6% and 84.6%, respectively, in cases no one of the three items was present).

CONCLUSIONS

schizophrenia patients evidenced significantly more craniofacial dysmorphology than controls. The model revealed in the study needs to be verified in larger samples and other populations.

Bone quality assessment in individuals of different age, gender and body constitution

The concept of bone quality describes the sets of the characteristics of the osseous tissue that influence bone strength. The aim was to explore the influence of anthropometric parameters and age on the parameters of the bone architecture and bone mineral properties in the lumbar vertebral bone of men and women. Vertebral bone samples underwent bone histomorphometry, bone densitometry and atomic absorption spectrometry. Men have greater values of the bone volume and thicker bone trabeculae in relation to women, which indicates that vertebral bone architecture is better preserved in men than in women. Age is the best predictor of changes that affect bone architecture and bone mineral properties. Bone mineral density value and calcium concentration are both negatively predicted by age, but positively predicted by body mass index. Such result supports the opinion that low body mass index is associated with conditions of bone deficit such are osteopenia and osteoporosis.

The relation between the serum calcium level and the complication incidence in haemodialysis uremic patients

The mineral metabolism disorder is the most influential factor of the morbidity and mortality incidence of haemodialysis uremic patients. The second most influential factor is the infection, which is the most frequent complication with an undesirable outcome. In recent times, the relation of the increased serum calcium and phosphorus level on the one hand, and the morbidity and mortality of that population in case on the other, has been observed. However, insufficient professional and scientific thought has been given to the relation of the lower serum levels of the aforementioned minerals and the morbidity and mortality incidence. We have researched the relation between lower serum calcium level (hypocalcaemia) and the complication incidence, especially infection. Throughout the time period of 18 months, 120 haemodialysis uremic patients were observed and 76 (63.3%) of them had serum calcium level below the lower threshold of referent values (9.0-9.5 mg/dL). In the patients with a lower serum calcium level (hypocalcaemia) a significant infection incidence (chi2 = 3.99; p = 0.0468), a significant sepses incidence (chi2 = 8.016; p = 0.04), a significant total complication incidence (p < 0.05) were determined, as well as a higher vascular access local infection incidence, but without statistically significant research results of this relation (chi2 = 0.098; p = 0.7598). We are of the belief that the incidence of the vascular access local infection should be examined on a greater number of patients; therefore, the significance of the examined relation in such an instance would be expected. The total infection incidence in all 120 observed patients is 3.8 for 100 months. It is to be concluded that the research findings indicate the association regarding the appearance of low serum calcium concentration (hypocalcaemia) and an increased complication incidence, especially the inflammation that leads to the requirement of further research in order to decrease morbidity, and consequently also the mortality of the observed population of patients by means of programmed therapy approach.

EPR study of a copper center in a single crystal of cytosine monohydrate

Copper is found incorporated into the crystal structure of cytosine monohydrate grown from aqueous solution of commercially available cytosine. Upon ionizing irradiation, the crystals exhibited the electron paramagnetic resonance (EPR) spectra characteristic of Cu(II) complex. Planar coordination bonding to the cupric ion, having three nitrogen atoms and an oxygen as ligands, is interpreted to bridge two cytosine molecules, replacing the two cytosine-cytosine hydrogen bonds present in pure crystals. The EPR signals are much stronger for crystals grown from the solutions to which small amount of copper powder were added.

Comparison of chromosome aberrations in peripheral blood lymphocytes from people occupationally exposed to ionizing and radiofrequency radiation

The genotoxic effects of occupational exposure to ionizing and non-ionizing radiation were investigated in 25 physicians and nurses working in hospitals and in 20 individuals working at radio-relay stations. Examination was conducted by chromosome aberration analysis of peripheral blood lymphocytes. The data showed that total number of chromosome aberrations in people exposed to ionizing and radio-frequency radiation (4.08 +/- 0.37 and 4.35 +/- 0.5 on 200 scored metaphases, respectively) were almost equally higher than those of non-irradiated subjects. The increase was in proportion to the number of individuals having more that 5-aberration/200 metaphases. Acentric fragments comprised the most frequently seen type of aberration. The average numbers in examined groups (11.8 x 10(-3) and 14.8 x 10(-3) per cell, respectively), were significantly higher than 4.2 x 10(-3), which was observed in controls, unexposed individuals. Dicentric fragments were also frequent (4.8 x 10(-3) and 6.25 x 10(-3), respectively, vs. 0.52 x 10(-3) in control). In contrast, the frequency of chromatid breaks increased only after ionizing radiation (3.8 x 10(-3) vs. 0.26 x 10(-3) in control). A positive correlation between the total number of chromosome aberrations and cumulative 6-years dosage was also found. The data emphasized the dangerous effects of prolonged exposure to both types of radiation and indicated that chromosomal aberration analysis should be obligatory for individuals working at radio-relay stations.
