Immersive Virtual Reality Therapy Is Supportive for Orthopedic Rehabilitation among the Elderly: A Randomized Controlled Trial

OBJECTIVE

This research aimed to determine the efficacy of VR therapy in mitigating symptoms of depression, anxiety, and stress among older adults following arthroplasty surgery and to comprehend the influence of psychological improvement on changes in functional outcomes.

METHODS

Utilizing a parallel-group randomized controlled trial design, the study involved 68 osteoarthritis patients who had recently undergone either total hip or knee arthroplasty. Subjects were split into two groups. The experimental group underwent eight VR therapy sessions during their rehabilitation, while the control group was given standard care. Assessments encompassed both psychological and functional outcomes, with tools like the Hospital Anxiety and Depression Scale, Perceived Stress Scale, and the Barthel Index, among others. The experimental group showcased notable enhancements in both psychological and functional areas compared to the control group.

RESULTS

A significant (p value of < 0.001) relationship was found between psychological progress and functional recovery, indicating that psychological factors can serve as predictors for functional outcomes.

CONCLUSIONS

The findings emphasize the promising role of VR therapy as a beneficial addition to the rehabilitation process for older adults' post-hip and knee arthroplasty. The integration of psychological interventions in standard rehabilitation practices appears valuable, but further studies are needed to ascertain the long-term advantages of such an approach.

Examining technology-assisted rehabilitation for older adults' functional mobility: a network meta-analysis on efficacy and acceptability

Technological advancements facilitate feedback adaptation in rehabilitation through virtual reality (VR) exergaming, serious gaming, wearables, and telerehabilitation for older adults fall prevention. Although studies have evaluated these technologies, no comparisons of their effectiveness have been conducted to date. Thus, this study aims to assess the differences in effectiveness of these interventions on balance and functional mobility in the older adults. A systematic review and network meta-analysis (NMA) were conducted to identify the most effective interventions for improving balance and functional mobility in adults aged 60 and over. The search was conducted in five databases (PubMed, Embase, Cochrane Central Register of Controlled Trials, Scopus, and Web of Science) up to June 10, 2023. The eligibility criteria were: (1) older adults, (2) functional mobility, balance, or gait as the primary outcome, (3) new technology intervention, and (4) randomized study design. New technology interventions were classified into five categories: exergaming with balance platforms or motion capture technologies, other serious gaming, interventions with wearables, and telerehabilitation. Additionally, two categories of control interventions (conventional exercises and no treatment) were extracted. The NMA was performed for the aggregated results of all outcomes, and separately for clinical functional scales, functional mobility, and gait speed results. Fifty-two RCTs with 3081 participants were included. Exergaming with motion capture was found to be statistically significant in producing a better effect than no treatment in the analysis of the functional mobility with an SMD of -0.70 (P < 0.01). The network meta-analysis revealed that exergaming with motion capture offers greater therapeutic benefits for functional mobility and balance compared to no treatment control. The effectiveness of this approach is similar to that of conventional exercises. Further RCTs are needed to provide a more definitive conclusion, particularly with respect to the effectiveness of serious games, telerehabilitation, and interventions with wearables.

Physical Activity Modifies the Severity of COVID-19 in Hospitalized Patients-Observational Study

BACKGROUND AND AIM

Physical activity (PA) can modulate the immune response, but its impact on infectious disease severity is unknown. We assess if the PA level impacts the severity of COVID-19.

METHODS

Prospective, cohort study for adults hospitalized due to COVID-19, who filled out the International Physical Activity Questionnaire (IPAQ). Disease severity was expressed as death, transfer to intensive care unit (ICU), oxygen therapy (OxTh), hospitalization length, complications, C-reactive protein, and procalcitonin level.

RESULTS

Out of 326 individuals, 131 (57; 43.51% women) were analyzed: age: median-70; range: 20-95; BMI: mean-27.18 kg/m²; and SD: ±4.77. During hospitalization: 117 (83.31%) individuals recovered, nine (6.87%) were transferred to ICU, five (3.82%) died, and 83 (63.36%) needed OxTh. The median for the hospital stay was 11 (range: 3-49) for discharged patients, and mean hospitalization length was 14 (SD: ±5.8312) for deaths and 14.22 days (SD: ±6.92) for ICU-transferred patients. The median for MET-min/week was 660 (range: 0-19,200). Sufficient or high PA was found in recovered patients but insufficient PA was observed in dead or ICU-transferred patients (p = 0.03). The individuals with poor PA had a higher risk of death (HR = 2.63; ±95%CI 0.58-11.93; p = 0.037). OxTh was used more often in the less active individuals (p = 0.03). The principal component analysis confirmed a relationship between insufficient PA and an unfavorable course of the disease.

CONCLUSION

A higher level of PA is associated with a milder course of COVID-19.

Validity and reliability of the Polish version of the Michigan Neuropathy Screening Instrument

BACKGROUND

Diabetic sensorimotor polyneuropathy is an important risk factor for foot ulceration and amputation. Thus, patients with diabetes should be screened for this disorder according to local guidelines. An obstacle to the diagnosis of this disease may be the lack of unified diagnostic criteria due to the lack of properly validated scales used for assessment.

AIM

To validate both sections (A and B) of the Michigan Neuropathy Screening Instrument (MNSI) in Polish (PL) patients with diabetes.

METHODS

A cross-sectional study using a test (A1, B1) and re-test (A2, B2) formula was performed in 80 patients with diabetes. The gold standard used for neuropathy detection was a nerve conduction study (NCS) which was performed in all participants. Reliability of the MNSI-PL was assessed using the Cronbach’s alpha, Kuder-Richardson formula 20 (KR-20), split-half reliability, the Gottman split-half tests, and correlation between first and second half was accessed. Stability was assessed using an intraclass correlation coefficient (ICC). For external validation, we used simple linear correlation, binomial regression, and agreement between two different tools using a Bland-Altman plot analysis.

RESULTS

The scale was internally consistent (Cronbach’s alpha for the full scale: 0.81 for A and 0.87 for B). MNSI-PL scores in test/retest showed high stability (ICC = 0.73 for A and ICC = 0.97 for B). The statistically important correlations between MNSI-PL and NCS were found for B1, B2, and A1 (P < 0.005). The cut-off points of ≥ 3 for section A (sensitivity of 90%-100%; specificity of 33%-40%) and ≥ 2 for section B (sensitivity of 81%-84%; specificity of 60%-70%) were obtained during neuropathy detection.

CONCLUSION

The MNSI-PL is a reliable and valid instrument in screening for diabetic neuropathy.

Long-Term Consequences of COVID-19 Disease Specific to Women: Exploratory Research

This study was designed to explore COVID-19 in a biopsychosocial model, taking into account the different mental and social consequences of the disease in women and men. A sociodemographic questionnaire containing anthropometric data, socioeconomic data, lifestyle data, health status before COVID-19, course of COVID-19, symptoms, and complications after COVID-19 was administered to 83 women and 64 men to investigate their mental health (MH) and quality of life (QoL). The Hospital Anxiety (HADS-A) and Depression (HADS-D) Scale, the Perceived Stress Scale (PSS-10) and the World Health Organization Quality of Life Scale Brief Version (WHOQOL-BREF) were adopted. Abnormal results in HADS-D and HADS-A were obtained in 33 (39.8%) women and 10 (15.6%) men and in 26 (31.3%) women and 14 (21.9%) men, respectively. Women experienced a lower level of QoL than men. The prolonged duration of COVID-19 symptoms was associated with increased anxiety in women during recovery. Good self-reported health before COVID-19 in women was associated with reduced QoL. Women had more symptoms of COVID-19 than men, and they experienced neurological complications more often. The presence of neurological complications in women appears to be associated with increased perceived anxiety and reduced QoL. This is an exploratory study whose results can influence future research with larger and more diverse samples.

The effectiveness of rehabilitation of patients with injuries as part of the Social Insurance Institution's disability prevention

BACKGROUND

Injuries are the cause of professional and social deactivation. The rehabilitation program provided under Social Security prevention pension enables earlier rehabilitation measures.

OBJECTIVE

The study's aim was to determine the efficiency of the rehabilitation as a part of Social Security prevention pension in the group of patients after limb injuries depending on the time when rehabilitation was undertaken.

METHODS

The study was a retrospective data analysis, based on medical histories of 93 patients after injuries, rehabilitated as part of Social Security prevention pension from January 2016 until July 2017. The effects of rehabilitation were assessed in 2 groups: early (up to 6 months from the injury) and late rehabilitation (over 6 months). Medical effects are based on measurements of the motion range in extremities' joints, functional test results and final evaluation of the rehabilitation.

RESULTS

For both groups, the motion range of most joints improved. Improvement among the group of early rehabilitated patients concerned everyday activities (p = 0.035), the results of medical rehabilitation (p = 0.046) and also the results of the functional tests.

CONCLUSION

Comprehensive rehabilitation of patients after the injuries in Social Security prevention pension leads to better medical effects. The results are better for earlier rehabilitated patients.

Evaluation of prognostic risk models for postoperative pulmonary complications in adult patients undergoing major abdominal surgery: a systematic review and international external validation cohort study

BACKGROUND

Stratifying risk of postoperative pulmonary complications after major abdominal surgery allows clinicians to modify risk through targeted interventions and enhanced monitoring. In this study, we aimed to identify and validate prognostic models against a new consensus definition of postoperative pulmonary complications.

METHODS

We did a systematic review and international external validation cohort study. The systematic review was done in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched MEDLINE and Embase on March 1, 2020, for articles published in English that reported on risk prediction models for postoperative pulmonary complications following abdominal surgery. External validation of existing models was done within a prospective international cohort study of adult patients (≥18 years) undergoing major abdominal surgery. Data were collected between Jan 1, 2019, and April 30, 2019, in the UK, Ireland, and Australia. Discriminative ability and prognostic accuracy summary statistics were compared between models for the 30-day postoperative pulmonary complication rate as defined by the Standardised Endpoints in Perioperative Medicine Core Outcome Measures in Perioperative and Anaesthetic Care (StEP-COMPAC). Model performance was compared using the area under the receiver operating characteristic curve (AUROCC).

FINDINGS

In total, we identified 2903 records from our literature search; of which, 2514 (86·6%) unique records were screened, 121 (4·8%) of 2514 full texts were assessed for eligibility, and 29 unique prognostic models were identified. Nine (31·0%) of 29 models had score development reported only, 19 (65·5%) had undergone internal validation, and only four (13·8%) had been externally validated. Data to validate six eligible models were collected in the international external validation cohort study. Data from 11 591 patients were available, with an overall postoperative pulmonary complication rate of 7·8% (n=903). None of the six models showed good discrimination (defined as AUROCC ≥0·70) for identifying postoperative pulmonary complications, with the Assess Respiratory Risk in Surgical Patients in Catalonia score showing the best discrimination (AUROCC 0·700 [95% CI 0·683-0·717]).

INTERPRETATION

In the pre-COVID-19 pandemic data, variability in the risk of pulmonary complications (StEP-COMPAC definition) following major abdominal surgery was poorly described by existing prognostication tools. To improve surgical safety during the COVID-19 pandemic recovery and beyond, novel risk stratification tools are required.

The impact of lockdown caused by the COVID-19 pandemic on glycemic control in patients with diabetes

PURPOSE

The aim the study was to assess the impact of the lockdown due to COVID-19 on diabetes control.

METHODS

The HbA1c value from a pre-lockdown visit (V1) from patients with diabetes was compared to the lockdown visit one (V2) after 3-5 months of its duration. Additional information on how the HbA1c changed and which variables can modify HbA1c during lockdown was also studied.

RESULTS

Records from 65 patients (type 2 diabetes -96,9%) were eligible and revealed that: HbA1c was at the target in 60% of the patients at V2 compared to 40% at V1; HbA1c decreased and normalized in 19, but worsened in 4 participants during the lockdown. No impact on HbA1c of: sex, age, diabetes duration, therapy type and modification before the pandemic, abandonment of the treatment, previous problems with glycemic control, or change in body weight and physical activity during the lockdown, was found. The previous macrovascular complications were the only variable that affected the increase in HbA1c (p = 0.0072), OR = 5.33.

CONCLUSIONS

The COVID-19 pandemic has not revealed worsened glycemic control in patients with type 2 diabetes, in general. The patients with macrovascular complications turned out to be at risk of the harmful impact of the restrictions on the HbA1c.

COVID-19 Vaccine Acceptance in Pregnant and Lactating Women and Mothers of Young Children in Poland

Purpose

The World Health Organization indicated vaccine hesitancy as one of the top 10 threats to global health. The success of a vaccine depends not only on its efficacy but also on its acceptance. Our study aims to define COVID-19 vaccine acceptance in a sample of pregnant and lactating women in Poland. Since mothers are often key decision-makers for whether their children will receive vaccination, it is vital to measure vaccine confidence among this group.

Patients and Methods

An anonymous online survey was distributed to assess the level of acceptance of COVID-19 vaccination among pregnant and lactating women for themselves and their children in Poland.

Results

The trust of pregnant and breastfeeding women and women who have offspring in government, in healthcare professionals, in scientific authorities, and sound scientific data is strongly associated with vaccine acceptance and may influence an individual's decision to perceive recommended actions as beneficial to the society as a whole.

Conclusion

Acceptance and confidence in receiving the COVID-19 vaccination among pregnant and lactating women and mothers with young children is strongly associated with feelings of trust in government, health professionals, scientific authorities, and sound scientific data. The dissemination of professional and reliable information regarding the safety and efficacy of COVID-19 vaccine uptake by qualified health care personnel can significantly increase the level of trust and public awareness regarding the safety and efficacy of COVID-19 vaccine uptake in pregnancy, while breastfeeding, and mothers with young children.

Analysis of a Trichinellosis Outbreak in Poland after Consumption of Sausage Made of Wild Boar Meat

An outbreak of trichinellosis due to the consumption of sausage made from wild boar meat unexamined for the presence of Trichinella spp. was reported in Poland in December 2020. The outbreak affected eight people. Examination of the sausages made of wild boar meat collected during epidemiological investigation indicated a high level of Trichinella spp. Larvae per gram (>30 lpg) and therefore the threat of an infection in humans after consumption of such product was significant. Over the years, the main source of trichinellosis in Poland has been wild boar meat, and the majority of trichinellosis cases were related to the consumption of traditional raw meat products such as Polish sausage. Taking this into account, there is the need for better education of consumers in the Trichinella spp. endemic regions and among cultures consuming traditional raw meat products.

Assessment of the level of anxiety and pain in women who do and do not attend childbirth classes during the SARS-CoV-2 pandemic

INTRODUCTION

Participation in childbirth classes is aimed at learning to cope with the anxiety that accompanies a woman during her pregnancy and childbirth. The aim of the study was to answer the question whether the lack of access to childbirth classes affected anxiety and perinatal pain in pregnant women who gave birth during the pandemic period.

MATERIALS AND METHODS

This cross-sectional survey-based study involved women who were pregnant during the lockdown period. The respondents were asked to fill in the following questionnaires: a personal questionnaire, the Polish version of the Delivery Fear Scale and the Numeric Rating Scale for the assessment of average and maximum pain experienced during the labour. The survey was completed within 24-72 hours after the birth of the child. The obtained questionnaires were divided into 2 groups based on the information concerning attending or not attending childbirth classes (divided into subgroups): group A - patients participated in childbirth classes, and group B - patients did not participate in childbirth classes.

RESULTS

Groups were homogeneous in terms of age, weight, height, body mass index and week of gestation. Perception of anxiety did not differ between groups. There was a correlation between particular formulation of the Delivery Fear Scale and "week of gestation" variable. In the group of women who gave birth naturally without anesthesia, there were no significant differences between groups in terms of mean and maximum pain during labour.

CONCLUSION

The level of anxiety and pain associated with childbirth is not modulated by childbirth classes during the pandemic period. There is s a correlation between particular formulation of the Delivery Fear Scale and "week of gestation" variable. In the group of women who gave birth naturally without anesthesia, there are no significant differences between groups in terms of mean and maximum pain during labour.

The psychological burden of long-term care facilities personnel during the SARS-COV-2 pandemic – a national survey in poland

Introduction

The high COVID-19 morbidity and mortality are observed among residents in long-term care facilities (LTCF) worldwide. Employees of LTCF, who are facing a critical epidemiological situation endangering the vulnerable residents, are exposed to pandemic’s psychological consequences daily.

Objectives

The main aim of this study was to assess psychological consequences (somatic symptoms, anxiety and insomnia, social dysfunction, and depression) among LTCF employees exposed to the SARS-CoV-2 pandemic crisis. Moreover, we investigated if factors such as: personal protective equipment (PPE) availability, safety guidelines or access to psychiatric and psychological support at the workplace, correlated with the level of psychological distress experienced by personnel.

Methods

A cross-sectional study was conducted among personnel of LTCF in Poland. The survey consisted of the sociodemographic section, the authors’ questionnaire with questions related to COVID-19 exposure, working conditions, access to PPE and mental health services, GHQ Questionnaire-28.

Results

show that access to PPE (P= .018), to workplace safety guidelines (P= .031), psychological support at workplace (P<0.01), fixed shift schedule (P= .05) and feeling that the right number of staff are employed in the workplace (P= .009), were related to the lower severity of psychopathological symptoms evaluated with the GHQ-28.

Conclusions

The study indicates an evidence that LTCF personnel are susceptible to the development of anxiety, depression, insomnia and social dysfunction during the pandemic crisis. However, these can be modified by: access to PPE, safety guidelines and psychological support. Findings from this study lay a basis for effective interventions aiming to support psychological health within this group.

Wide spectrum of clinical picture of COVID-19 in children - From mild to severe disease

INTRODUCTION

Children account for a relatively small proportion of laboratory-confirmed SARS-CoV-2 infections. In children, COVID-19 usually has a relatively mild course. However, in rare cases, severe disorders can be observed, and clinical manifestations may differ from adults.

PURPOSE

The aim of this study is to analyse the frequency, clinical picture and outcome of COVID-19 in children based on the experience from the tertiary care centre and regional sanitary-epidemiological office.

METHODS

We report a study regarding 106 cases of confirmed SARS-CoV-2 infection cases in PCR from a nasopharyngeal swab (age range 1-month - 17-years). In all cases, history was taken. In children who required hospital admission, physical examination and laboratory test were performed according to clinical indications.

RESULTS

Twelve of the patients required admission to the hospital. The most common symptoms were anosmia and dysgeusia (75%) and headaches (49%) in outpatients and fever in hospitalised children (75%). Three children from the hospitalised group developed a severe course with increased inflammatory indexes. The clinical picture was more severe in younger children from the hospitalised group. Treatment options were regarded individually in all cases.

CONCLUSION

Our study is the first tour knowledge regarding the clinical course of COVID-19 in Polish children. In general, the clinical course of COVID-19 was mild with anosmia and dysgeusia as the most common symptoms. However, in hospitalised children, a severe progression of the disease and less typical signs as aplastic anaemia may be developed.

Immersive Virtual Reality Therapy as a Support for Cardiac Rehabilitation: A Pilot Randomized-Controlled Trial

Depression and anxiety can significantly reduce the effectiveness of cardiac rehabilitation (CR). Several studies have assessed the effectiveness of virtual reality (VR)-based interventions for symptoms of anxiety and depression; however, they do not relate to patients with heart disease. The aim of this study was to assess the effects of VR therapy on the mental state of patients with coronary artery disease (CAD). Thirty-four CAD patients with elevated anxiety or depression symptoms were recruited. After randomization, 17 participants were assigned to the intervention group, and 17 to the control group. Both groups underwent standard CR for outpatients. In the intervention group, eight VR therapy sessions were applied. In the control group, eight sessions of Schultz' Autogenic Training were applied. To assess patient mental states, Hospital Anxiety and Depression Scale (HADS) and Perception of Stress Questionnaire (PSQ) were used, before and after 4 weeks of CR. In the intervention group, a significant decrease in HADS score was observed (19.46 pretreatment vs. 15.73 post-treatment, p = 0.003), HADS-Anxiety subscale decreased by 16.0 percent (p = 0.01) and HADS-Depression by 23.0 percent (p = 0.003). Similarly, a significant decrease in PSQ was recorded at 12.8 percent (64.73 vs. 56.47, p = 0.03). In the control group, HADS and PSQ data did not change. VR therapy significantly reduced the severity of depressive symptoms, anxiety, and stress levels in CAD patients undergoing CR. Immersive VR therapy effectively supports the CR of individuals with anxiety-depressive symptoms. ClinicalTrials.gov (NCT04045977).

Does the Meeting Centre Support Programme decrease the experience of stigmatisation among people with cognitive deficits?

OBJECTIVES

This is the first study to focus on the role and impact of a psychosocial intervention, the Meeting Centre Support Programme (MCSP), for people living with dementia and mild cognitive impairment (MCI) on the experience of stigmatisation across three different European countries.

METHOD

A pre/post-test control group study design compared outcomes for 114 people with dementia (n=74) and MCI (n=40) in Italy, Poland and the UK who received either the MCSP or usual care (UC). The 'Stigma Impact Scale, neurological disease' (SIS) was administered at two points in time, 6 months apart. The Global Deterioration Scale (GDS) was used to assess the level of cognitive impairment.

RESULTS

Although statistical analysis did not show any significant differences between MCSP and UC at pre/post-test for the 3 countries combined, there were significant results for individual countries. In Italy, the level of SIS was significantly lower (p=0.02) in the MCSP group following the intervention. The level of Social Isolation increased significantly (p=0.05) in the UC group at follow-up in Poland. The level of Social Rejection was significantly higher (p=0.03) over time for UK participants receiving MCSP compared to UC.

CONCLUSION

The experience of stigma by people living with dementia and MCI is complex and there may be different country specific contexts and mechanisms. The results do not enable us to confirm or disconfirm the impact of a social support programme, such as MCSP, on this experience. Difficulties in directly measuring the level of stigma in this group also requires further research.

Use of virtual reality-based training in different fields of rehabilitation: A systematic review and meta-analysis

OBJECTIVES

To analyse the effectiveness of virtual reality-based interventions within several fields of rehabilitation, and to investigate whether the outcomes of virtual reality-based interventions, in terms of upper or lower limb function, gait and balance, differ with respect to the virtual reality system used.

METHODS

A search of PubMed database resulted in an initial total of 481 records. Of these, 27 articles were included in the study. A final total of 20 articles, with neurological, orthoapedic, geriatric or paediatric patients, published between 2012 and 2019, were included in the study. Two independent reviewers selected potentially relevant articles based on the inclusion criteria for full-text reading. They extracted data, and evaluated the methodological quality of each study.

RESULTS

Seventeen studies were included in the meta¬ -analysis. Eight studies analysed upper limb function, with no significant evidence that specialized VR is superior to conventional treatment. Regarding FuglMeyer scale results, the effect of specialized virtual reality therapy was found to be significantly better than conventional treatment. No significant differences between specialized VR and conventional treatment were observed in effects on hand dexterity and gait. There was a significant difference in effects on balance in favour of specialized virtual reality as compared to conventional treatment. Gaming virtual reality was significantly better than conventional treatment for upper limb function, but not for hand dexterity, gait and balance.

CONCLUSION

Use of specialized virtual reality and gaming virtual reality can be advantageous for treatment of the upper extremity, but not for hand dexterity and gait in all pathologies considered. Specialized virtual reality can improve balance in neurological patients.

The Role of Self-Efficacy in the Recovery Process of Stroke Survivors

Introduction

Belief in one’s personal capabilities are conducive to achieving success and provides additional energy for action. The stronger the conviction of one’s self-efficacy, the higher the self-goals and the stronger the commitment to achieving them, despite any adversities. Our knowledge regarding the role of self-efficacy in post-stroke rehabilitation is still scarce.

Aim of the Study

The study aimed to analyze characteristics related to high self-efficacy levels before and after rehabilitation and to determine the role of self-efficacy in this process.

Materials and Methods

The study involved 99 stroke survivors. Participants’ mental and functional state were assessed using Generalized Self-Efficacy Scale (GSES), Barthel Index (BI), Acceptance of Illness Scale (AIS), Geriatric Depression Scale (GDS), Visual Analogue Scale for Pain (VAS), Instrumental Activities of Daily Living (IADL) and Rivermead Mobility Index (RMI). Patients were evaluated twice: on admission (T₁) and 3 weeks into rehabilitation (T₂).

Results

Patients without self-efficacy improvement after 3 weeks of rehabilitation, on discharge from the ward demonstrated poorer well-being (p = 0.002, Hedges’ g = 0.63, 95% CI [0.24–1.08]), lower illness acceptance levels (p < 0.001, Hedges’ g = −0.78, 95% CI [−1.25 – −0.41]), poorer functional status in basic activities of daily living (p = 0.003, Hedges’ g = −0.62, 95% CI [−1 – −0.25]), locomotive abilities (p = 0.004, Hedges’ g = −0.58, 95% CI [−1.12 – −0.15]) and instrumental activities of daily living (p = 0.001, Hedges’ g = −0.71, 95% CI [−1.15 – −0.34]).

Conclusion

Self-efficacy level is significantly related to rehabilitation outcomes. A routine self-efficacy assessment during the rehabilitation process seems very important. Patients whose initial self-efficacy is low or remains unchanged despite rehabilitation require special attention. Close cooperation between all members of the therapeutic team is essential to strengthen, at each stage, the sense of self-efficacy in stroke survivors.

Needs of Older People Attending Day Care Centres in Poland

Introduction: Day care centres (DCC) aim to support older adults living in their own homes by providing a variety of activities to promote the independence of those people and reduce the caregiver’s burden. In Poland, there are no standards for providing this form of care. The provided care is delivered by different organisations, and there is a lack of quality control in the majority of places. Regrettably, in Poland, there is a paucity of research on the holistic needs of the elderly attending DCC. Aim of this study: This is the first study which has aimed to identify the Polish day care centres attendees’ needs to ensure that the increasing number of older people receive the best possible care, and as a part of the quality improvement process for recommendation development of the new day care services model in Poland within the ‘Homely Marina’ project. Methods and Materials: A representative sample (n = 269) was randomly selected from day care centres attendees (estimated as 10,688) in Poland. An anonymous survey for the assessment of needs was developed by the authors. Results: The respondents assessed the level of provided services as very good or good. Best rated services included meals, supportive and welfare services (occupational therapy, music therapy, art therapy, cognitive training). Almost half of the participants indicated the need for company as the main reason to attend a DCC. This research reveals a lack of support with regard to additional staff: e.g., a nurse. Conclusions: In Poland, the services offered in DCC should focus on social isolation and sense of loneliness prevention, and maintenance of social activity of the elderly. The presented analysis of needs in Polish day care centres suggests a need for changes which may improve the quality of services. There is a great need to find a balance between home-based care and in-patient care, using better integration of available services and strengthening support for informal caregivers. Robust research with a collection of meaningful outcomes is required to ensure that in Poland, the increasing number of older people is enabled to access high-quality day care service provision.

Virtual reality in psychiatric disorders: A systematic review of reviews

BACKGROUND

Virtual reality (VR) is being used more and more often as a therapeutic tool in psychology or psychiatry. In recent years, VR interventions appear more extensively also in disorders such as depression, anxiety and phobia. However, there has yet to be a comprehensive synthesis and critical review of the literature to identify future directions to advance the field in this area.

OBJECTIVES

To broadly characterize the literature to date on the application of VR in psychiatric disorders by conducting a systematic review of reviews, describe the limitations of existing research, suggest avenues for future research to address gaps in the current literature and provide practical recommendations for incorporating VR into various treatments for psychiatric disorders.

METHODS

PubMed and Web of Science databases were searched for reviews on VR use in psychiatric disorders (e.g. various pain perceptions, post-traumatic stress disorder, phobias, attention deficit hyperactivity disorder, psychosis, depression). The methodological quality of each literature review was assessed using AMSTAR.

RESULTS

The original search identified 848 reviews, of which 70 were included in the systematic review of reviews. Broadly, the literature indicates that various VR interventions could be useful in different psychiatric disorders.

CONCLUSION

This study provides evidence supporting the positive impact of VR therapy in psychiatric disorders. However, the impact is defined differently according to the studied area. Nevertheless, due to the continuous development of VR hardware and software, it is essential to conduct further research in the area of psychiatric disorders, especially as no review has concluded that VR does not work.

SARS-CoV-2 pandemic and the population with dementia. Recommendations under the auspices of the Polish Psychiatric Association

SARS-CoV-2 poses a particular risk to the elderly and people with many comorbidities. In the case of people with dementia, the compliance with sanitary recommendations and the necessary physical isolation can have far-reaching negative consequences in terms of limiting the continuation of tailored care, support and treatment. The recommendations related to the SARS-CoV-2 pandemic must take into account not only the medical consequences of lack of access to medical care, but also their long-term effects and the disease progression in accordance with the concept of social health. A plan of action for the psychoeducation of informal carers, adapted to the elderly group (including people with dementia), is also necessary. Prepared under the auspices of the Polish Psychiatric Association, the recommendations for people living alone, with their family and in long-term care facilities are intended to draw attention to key epidemiological issues that can be planned by medical staff within the organization of patient care. However, mental and social needs of patients, whose fulfilment is particularly significant in times of restrictions related to everyday activities, are of equal importance. Further monitoring of the epidemiological situation and scientific reports related to the SARS-CoV-2 pandemic are necessary to verify and update the guidelines.

1,000,000 cases of COVID-19 outside of China: The date predicted by a simple heuristic

We forecast 1,000,000 COVID-19 cases outside of China by March 31st, 2020 based on a heuristic and WHO situation reports. We do not model the COVID-19 pandemic; we model only the number of cases. The proposed heuristic is based on a simple observation that the plot of the given data is well approximated by an exponential curve. The exponential curve is used for forecasting the growth of new cases. It has been tested for the last situation report of the last day. Its accuracy has been 1.29% for the last day added and predicted by the 57 previous WHO situation reports (the date 18 March 2020). Prediction, forecast, pandemic, COVID-19, coronavirus, exponential growth curve parameter, heuristic, epidemiology, extrapolation, abductive reasoning, WHO situation report.

Abdominal muscles activity during abdominal bracing and posterior pelvic tilt in women after natural birth and after caesarean delivery

Purpose: Exercises after pregnancy can reduce the severity and risk of postnatal locomotor system disorders and muscular dysfunctions. The aim of the study was to evaluate electromyographic activity of abdominal muscles in women who gave birth naturally and via a caesarean section, and to compare it to a group of women who have never given birth. Methods: 27 women were included into the study after completing the personal questionnaire and functional examination. The surface electromyography during abdominal bracing and posterior pelvic tilt was used to test rectus abdominis muscles and internus oblique/ transversus abdominis muscles bilaterally. After normalization test, patients were asked to perform abdominal bracing and posterior pelvic tilt exercises. Results: Activity of rectus abdominis muscle is higher in posterior pelvic tilt compared to abdominal bracing. It should be noted that the internus oblique/transversus abdominis muscle activity in both exercises is similar. Conclusions: In women after natural birth and after a cesarean section who experienced no locomotor system symptoms, no statistically significant differences in abdominal muscle activity in both exercises were observed. In each group being studied, posterior pelvic tilt activated rectus abdominis muscles to a greater extent than just bracing.

Abdominal muscles activity during abdominal bracing and posterior pelvic tilt in women after natural birth and after caesarean delivery

PURPOSE

Exercises after pregnancy can reduce the severity and risk of postnatal locomotor system disorders and muscular dysfunctions. The aim of the study was to evaluate electromyographic activity of abdominal muscles in women who gave birth naturally and via a caesarean section, and to compare it to a group of women who have never given birth.

METHODS

27 women were included into the study after completing the personal questionnaire and functional examination. The surface electromyography during abdominal bracing and posterior pelvic tilt was used to test rectus abdominis muscles and internus oblique/ transversus abdominis muscles bilaterally. After normalization test, patients were asked to perform abdominal bracing and posterior pelvic tilt exercises.

RESULTS

Activity of rectus abdominis muscle is higher in posterior pelvic tilt compared to abdominal bracing. It should be noted that the internus oblique/transversus abdominis muscle activity in both exercises is similar.

CONCLUSIONS

In women after natural birth and after a cesarean section who experienced no locomotor system symptoms, no statistically significant differences in abdominal muscle activity in both exercises were observed. In each group being studied, posterior pelvic tilt activated rectus abdominis muscles to a greater extent than just bracing.

Analysis of the degree of acceptance of illness among older adults living in a nursing home undergoing rehabilitation - an observational study

Introduction: The factors that influence the rehabilitation process among older adults remain unclear. The aim of the study was to assess the acceptance of illness and related factors (socio-demographic data, cognitive status, depression symptoms and functional status) among patients living in a nursing home who are undergoing rehabilitation.

Sample and methods: A total of 119 elderly patients were examined, of whom 96 were included in the research project. All participants were assessed using the following tests: Mini Mental State Examination, Acceptance of Illness Scale, Geriatric Depression Scale and Barthel Index. Tests were conducted at two time points, the first upon admission to the ward and the second after 3 months of regular rehabilitation.

Results: The study group showed relatively low scores for illness acceptance. After 3 months of rehabilitation, the acceptance of illness had significantly improved, but still remained at a low level. The results showed a relationship between acceptance of illness and patients’ depression symptoms, functional status and cognitive status.

Conclusions: The results suggest that assessment of the acceptance of illness among patients living in Nursing Home is important during treatment and rehabilitation process; however, further studies are necessary.

The role of biopsychosocial factors in the rehabilitation process of individuals with a stroke

BACKGROUND:

A large proportion of individuals with a stroke are unable to return to work, although figures vary greatly. Due to the very high cost of post-stroke care, both tangible and intangible, in the form of long-term social consequences, it seems extremely important to search for factors responsible for the low efficiency of the rehabilitation and recovery process, because this fact has direct influence on future employment. Such knowledge would enable physiotherapists to quickly identify those patients who are at risk of rehabilitation breakdown, in order to provide them with special care and include them in intensive therapeutic treatments.

OBJECTIVE:

The aim of the study was to assess the efficacy of post-stroke rehabilitation, evaluated within the biopsychosocial aspect.

METHODS:

The study consisted of 120 patients after first stroke, including 48 women and 72 men aged 58.0 (±8.6). The measure of the effects of physiotherapy in the present study was not only the improvement of the functional state (simple and complex activities of daily life, locomotive activities), but also the improvement of the mental state (mood and the sense of well-being, level of acceptance of illness, perceived self-efficacy) and the reduction of pain. The Mini-Mental State Examination, the Geriatric Depression Scale, the Generalized Self-Efficacy Scale, the Acceptance of Illness Scale, the Visual Analogue Scale, the Barthel Index, the Instrumental Activity of Daily Living and the Rivermead Mobility Index were used. All parameters were measured twice: on admission to the ward and after three weeks of physiotherapy. The characteristics of the study group were presented using descriptive statistics. The analysis of interdependence of the efficacy of physiotherapy used two non-parametric tests: the Mann-Whitney U test to compare two groups, and the Kruskal-Wallis ANOVA test to compare a greater number of groups. Correlations between characteristics with continuous distributions were assessed using Spearman’s rank correlation coefficient (ρ), and in case of categorical variables, Pearson’s chi-squared (χ²) correlation coefficient. Linear regression was used to determine the hierarchy of the influence of particular characteristics on the efficacy of physiotherapy.

RESULTS:

Statistical analyzes show that patient’s age, time since stroke, number of comorbidities, family care capacity, marital status of the patient and also a low level of acceptance of illness, depression symptoms and lack of a sense of self-efficacy were related with low efficacy of post-stroke rehabilitation

CONCLUSIONS:

Comprehensive neurological rehabilitation, taking into account mental challenges and socio-economic circumstances of individuals with a stroke is essential in order to achieve high efficacy of physiotherapy. Important external factors may play a pivotal role in returning to work as well and should be taken into account during rehabilitation. Of interest should be to assess more biopsychological factors, such as acceptance of illness and a sense of self-efficacy referred to as barriers to return to work.

Does the Meeting Centres Support Programme reduce unmet care needs of community-dwelling older people with dementia? A controlled, 6-month follow-up Polish study

Introduction

In Poland we lack a multidisciplinary and coordinated system of care for people with dementia, which would take the form of an evidence-based pathway and the number of reports on the holistic approach to caring for people living with this diagnosis is very low.

Aim of the study

The aim of the study was to investigate whether the Meeting Centres Support Programme (MCSP) is effective in meeting the needs of older people with dementia.

Participants and methods

This was done by comparing the experiences of people with dementia themselves and that of their carers at baseline and at follow-up, after 6 months of participation in MCSP or Usual Care (UC).

Results

The study included 47 people diagnosed with mild-to-moderate dementia (n=24, MCSP group; n=23, UC control group) and 42 informal carers (n=22, MCSP group; n=20, UC control group), all living in Wroclaw in Poland and involved in the European JPND-MEETINGDEM project. To assess cognitive functioning and severity of dementia, the Mini-Mental State Examination and Global Deterioration Scale were used. The needs were assessed using the Camberwell Assessment of Need for the Elderly. The most frequently reported unmet needs at baseline both by the persons with dementia and their carers included activities of daily living, psychological distress, and the need for company. Compared to the UC group the unmet needs were reduced considerably in the MCSP group providing convincing evidence that MCSP is effective in reducing unmet needs over a 6-month period.

Conclusion

MCSP may be regarded as a good example of comprehensive post-diagnostic support for patients with mild-to-moderate dementia as well as their informal carers.

Complexity of Antibiotic Resistance in Commensal Escherichia coli Derived from Pigs from an Intensive-Production Farm

Antibiotics in animal husbandry are used to maintain welfare, but lead to the generation of resistant strains. We analyzed commensal multidrug-resistant Escherichia coli from pigs at the beginning and end of the production cycle in a farm with a farrow-to-finish system in order to investigate whether clonal spread or horizontal gene transfer constitutes the main factor responsible for the prevalence of resistance in this environment. Among 380 isolates, 56 multidrug-resistant E. coli with a similar resistant phenotype were selected for more detailed investigations including a genomic similarity analysis and the detection of mobile elements. Isolates carried bla_TEM-1, aadA1, strA/B, tetA, tetB, tetC, dfrA1, dfrA5, dfrA7, dfrA12, sul1, sul2, sul3, and qnrS resistance genes, with the common co-occurrence of genes encoding the same resistance phenotype. A pulse-field gel electrophoresis analysis of the genomic similarity of multidrug-resistant E. coli showed ≤65% similarity of most of the tested strains and did not reveal a dominant clone responsible for the prevalence of resistance. Class 1 and 2 integrons and transposons 7 and 21 were detected among mobile elements; however, some were truncated. Plasmids were represented by 11 different incompatibility groups (K, FIB, I1, FIIA, FIC, FIA, Y, P, HI1, B/O, and T). Genetic resistance traits were unevenly spread in the clonal groups and suggested the major rearrangement of genetic material by horizontal gene transfer. The present results revealed that in commensal E. coli from pigs in a homogeneous farm environment, there was no dominant clone responsible for the spread of resistance and persistence in the population.

FIMA, the questionnaire for health-related resource use in the elderly population: validity, reliability, and usage of the Polish version in clinical practice

Purpose

The purpose of this study was to determine the validity and reliability of the Polish version of the Questionnaire for Health-Related Resource Use in an Elderly Population [Fragebogen zur Inanspruchnahme medizinischer und nicht-medizinischer Versorgungsleistungen im Alter (FIMA)].

Patients and methods

This was a cross-sectional study conducted in a rehabilitation care unit in Poland between January and June of 2017. Sixty-one patients aged ≥65 years who had been admitted to the unit were enrolled into the study. Each participant was evaluated twice: once within 48 hours of admission (T1) and once after 2 weeks (T2).

Results

The translated instrument was understood by most respondents in a selected population and it maintained a reading and comprehension level that was accessible by most respondents, even of a low education level. With the aid of the prevalence-adjusted bias-adjusted kappa (PABAK) and intraclass correlation coefficient (ICC), 100% test–retest reliability for 10 out of the 12 questions that were subjected to analysis was indicated. The most frequent health-related resource uses were appointments at the general practitioner (90.2%) and orthopedist (54.1%), medication (93.4%), and the necessity to have glasses as supportive equipment (70.5%).

Conclusion

The Polish FIMA demonstrated very good test–retest reliability, good validity, and ease of use for elderly people. Further investigation is required. In the future, the routine use of this instrument could be encouraged to assess the use and demand for medical and nonmedical services among the elderly.

Comparison of Commensal Escherichia coli Isolates from Adults and Young Children in Lubuskie Province, Poland: Virulence Potential, Phylogeny and Antimicrobial Resistance

Commensal Escherichia coli population is a dynamic structure which may be important in the pathogenesis of extraintestinal infections. The aim of this study was the comparison of genetic diversity of commensal E. coli isolates from two age group—adults and young children. E. coli strains were isolated on MacConkey agar and identified by biochemical tests. Determination of four major phylogenetic groups, identification of virulence genes and antimicrobial resistance determinants were performed by using multiplex or simplex PCR. Phenotypic analysis of resistance was based on disc-diffusion method. The prevalence of virulence genes was significantly higher among isolates from adults than from young children. Phylogroup B2 predominated among E. coli from adults, whereas phylogroup A was the most common in isolates from young children. The analyses of antimicrobial resistance revealed that resistance to at least one antimicrobial agent and multidrug-resistance were detected significantly more frequent in the isolates from adults than from young children. This study documented that the commensal E. coli isolates from adults showed greater genetic diversity than from young children and constitutes a substantial reservoir of the virulence genes typical for extraintestinal pathogenic E. coli.

Met and unmet care needs of older people with dementia living at home: Personal and informal carers’ perspectives

In Poland, there are few reports of the holistic approach to caring for older people with dementia. The aim of this study was to assess the needs of people with dementia living at home. This was done by evaluating the perspective of people with dementia themselves and that of their carers. The study included 47 people diagnosed with mild to moderate dementia and 41 informal carers, all living in Wroclaw in Poland, involved in the MeetingDem project. The needs were assessed using the CANE. Other scales used were: the MMSE, the GDS and the QOL-AD. The carers reported significantly more needs, both met and unmet, than the people with dementia themselves. The most frequent reported unmet needs both by the people with dementia and their carers included activities of daily living, psychological distress and the need for company. Based on this study’s findings, tailored multidisciplinary treatment, adjusted to their needs and wishes, can be offered thus creating integrated and individualised support.

Alginate based hydrogel for tissue regeneration: optimization, antibacterial activity and mechanical properties

Purpose: In this work our aim was to reveal the relationship between sodium alginate concentration and crosslinking level, also the ratio of release of the antibacterial additives: silver nanoparticles and metronidazole. Moreover, we examine obtained hydrogel as a potential dressing material for regenerative medicine. Design/methodology/approach: In the research specimens of hydrogels were tested to define their mechanical and physicochemical properties like antibacterial activity against gramnegative Escherichia coli and gram-positive Staphylococcus aureus, viscosity and conductivity. Findings: The concentration of alginate and presence of antibacterial additives influence on the crosslinking level. Mechanical properties of hydrogels are similar to human skin. Only hydrogels with addition of metronidazole and AgNP inhibits bacteria growth after 18 h. In case of gram-negative Escherichia coli both of the aseptic additives inhibits bacteria growth, but sodium alginate hydrogel with silver nanoparticles gives better results in tests with grampositive Staphylococcus aureus. Research limitations/implications: The presence of metronidazole in hydrogel, especially its incorporation and binding with mannuronic and guluronic acid residues must be clarified in more advanced research. Practical implications: Obtained results shows that sodium alginate hydrogels with 0.1mg/ml of alginate, due to its properties are proper as a dressing material. Based on the results, and more advanced tests with metronidazole, we can consider dressing design. Originality/value: Unique value of this work is that we completed the gap in knowledge about the relation of crosslinking level and mechanical properties with are crucial to proper tissue healing and addition of popular aseptic agents.

The impact of compression garments on the quality of life in patients with chronic venous disease

Introduction. Assessment of quality of life in patients suffering from chronic venous disease of the lower extremity who were treated with compression garments. Methods. Patients of both sexes aged 30-75 years with chronic venous disease and at least varices, but without active ulceration, were qualified for the study. To assess the quality of life, the CIVIQ-20 questionnaire was used before and after 4 weeks of compression therapy with second class compression. Results. The combined results of the CIVIQ scale rose from 61.49% before compression to 75.17% after 4 weeks of compression therapy (p 0.01). No correlation was found between sex, age, career status or type of work and the averaged CIVIQ score. Conclusions. Compression therapy with special garments significantly improves the quality of life in patients with chronic venous disease. Larger studies are still needed in this field.

[The neuroprotective effect of mild therapeutic hypothermia after out-of-hospital cardiac arrest with successful reanimation - a case report]

The use of mild therapeutic hypothermia (MTH) in adult patients remaining in a coma following cardiac arrest, regardless of its mechanism and location, is recommended by the European Resuscitation Council. The study presents a case of a 52-year-old man in whom MTH was used following successfully resuscitated out-of- hospital sudden cardiac arrest caused by ventricular fibrillation. On the basis of this case it was indicated that the use of low temperatures may be an effective method of neuroprotective treatment since such activity is compatible with later observed great possibility of the brain to compensate and with the maintenance of brain plasticity which is crucial for neuropsychological rehabilitation.

[Well-known and new variants of pathogenic Escherichia coli as a consequence of the plastic genome]

E. coli is a diverse bacterial species encompassing commensal as well as intestinal and extraintestinal pathogenic strains. The ability to adapt to so many different niches in the host organism is determined by the extreme genomic plasticity of E. coli. The genetic diversity is due to a complex phylogenetic structure in which besides the well-known main groups A, B1, B2 and D, four new groups, C, E, F and Clad I, have been characterized recently. The mobile gene pool exchanged by horizontal gene transfer (HGT) is another important driving force in the evolution of E. coli. Pathogenicity of strains is conditioned by a specific repertoire of virulence factors located on the mobile genetic elements and transmitted by HGT. The environment changing constantly stimulates the formation of new virulence gene combinations that generate the formation, not observed so far, of new pathogenic clones of higher capacity for virulence and greater expansiveness. The presence of very similar virulence plasmids carrying conserved combinations of the virulence genes (CVP) among extraintestinal pathogenic strains in humans and birds has been observed. It indicates a real possibility of occurrence of common virulence factors. The increase in drug resistance among pathogenic E. coli is also reflected in the prevalence of highly expansive clones exhibiting both high virulence and resistance. The presented data indicate that further studies are required to determine the interdependencies of resistance and virulence at the genetic level to help improve our management of the infectious diseases caused by these bacteria.

Antimicrobial resistance in commensal Escherichia coli from pigs during metaphylactic trimethoprim and sulfamethoxazole treatment and in the post-exposure period

The prevalence of trimethoprim (TMP) and sulfamethoxazole (SMX) resistance in commensal E. coli from pigs was tested in this study. E. coli was derived from three groups of piglets in successive stages of metaphylactic therapy and from two groups of sows 10 and 18 weeks after the treatment. MIC values of TMP and SMX were determined for a total of 352 strains. The presence of resistance genes (dfrA1, dfrA5, dfrA7, dfrA12, dfrA17, sul1, sul2, sul3) and class 1 and 2 integron-associated dfrA gene cassettes was tested. Resistance to TMP was very high during the administration of the antimicrobial (from 97 to 100%) and amounted to 86% and 69% in the post-exposure period; MIC > 32 mg/L. The isolates from all groups of pigs were resistant to sulfamethoxazole, with MIC > 1028 mg/L. The dfrA1 and sul1 genes (as part of integrons) dominated in E. coli from piglets, but the dfrA12 and sul1 genes were prevalent in E. coli from sows. Coexistence of the different dfrA genes was detected in 71 isolates from all groups of swine. Transcription analysis revealed that most of these genes were not transcribed, particularly gene cassettes of class 1 integrons. The research revealed a high level of resistance associated with the metaphylactic treatment, persistence and circulation of resistance in bacterial populations. Diverse genetic background with multiple and not transcribed resistance genes was observed.

Prevalence of virulence determinants and antimicrobial resistance among commensal Escherichia coli derived from dairy and beef cattle

Cattle is a reservoir of potentially pathogenic E. coli, bacteria that can represent a significant threat to public health, hence it is crucial to monitor the prevalence of the genetic determinants of virulence and antimicrobial resistance among the E. coli population. The aim of this study was the analysis of the phylogenetic structure, distribution of virulence factors (VFs) and prevalence of antimicrobial resistance among E. coli isolated from two groups of healthy cattle: 50 cows housed in the conventional barn (147 isolates) and 42 cows living on the ecological pasture (118 isolates). The phylogenetic analysis, identification of VFs and antimicrobial resistance genes were based on either multiplex or simplex PCR. The antimicrobial susceptibilities of E. coli were examined using the broth microdilution method. Two statistical approaches were used to analyse the results obtained for two groups of cattle. The relations between the dependent (VFs profiles, antibiotics) and the independent variables were described using the two models. The mixed logit model was used to characterise the prevalence of the analysed factors in the sets of isolates. The univariate logistic regression model was used to characterise the prevalence of these factors in particular animals. Given each model, the odds ratio (OR) and the 95% confidence interval for the population were estimated. The phylogroup B1 was predominant among isolates from beef cattle, while the phylogroups A, B1 and D occurred with equal frequency among isolates from dairy cattle. The frequency of VFs-positive isolates was significantly higher among isolates from beef cattle. E. coli from dairy cattle revealed significantly higher resistance to antibiotics. Some of the tested resistance genes were present among isolates from dairy cattle. Our study showed that the habitat and diet may affect the genetic diversity of commensal E. coli in the cattle. The results suggest that the ecological pasture habitat is related to the increased spreading rate of the VFs, while the barn habitat is characterised by the higher levels of antimicrobial resistance among E. coli.

Type 1 fimbriae in commensal Escherichia coli derived from healthy humans

Type 1 fimbriae are one of the most important factors of Escherichia coli adaptation to different niches in the host. Our study indicated that the genetic marker--fimH gene occurred commonly in commensal E. coli derived from healthy humans but expression of the type 1 fimbriae was not observed. Identification of fim structural subunit genes (fimA-fimH) and recombinase fimE and fimB genes showed that many of the strains were carrying an incomplete set of genes and the genes expression study revealed that in strains with complete set of fim genes, the fimC gene, encoding the chaperone protein, was not expressed.
