[Psychosocial effects of the pandemic on staff and residents of nursing homes as well as their relatives-A systematic review]

Hintergrund

Die COVID-19-Pandemie stellt Bewohner von Altenpflegeeinrichtungen, deren Angehörige bzw. Besucher ebenso wie Mitarbeitende vor große Herausforderungen. Viruseindämmende Maßnahmen wirken sich stark auf das Wohlbefinden der betroffenen Personengruppen aus.

Material und Methode

Systematische Literatursuche nach Studien zu psychosozialen Folgen der Pandemie für Bewohner, deren Angehörige bzw. Besucher sowie Mitarbeitende und Zusammenführung der Ergebnisse mittels narrativer Synthese.

Ergebnisse

Es wurden 756 Studien gesichtet, davon 15 Arbeiten eingeschlossen. Die Daten wurden zwischen Februar und Juni 2020 mit Teilnehmenden aus 14 Ländern erhoben. Es wurden v. a. Einsamkeit, Trauer und Depressivität, aber auch Angst, als häufige Reaktionen der Bewohner auf die Kontakt- und Besuchsrestriktionen berichtet. Bewohner mit kognitiven Einschränkungen litten stärker unter den Auswirkungen, auch wenn es gegenteilige Hinweise gibt. Angehörige bzw. Besucher berichteten ebenfalls von einer Zunahme ihrer Einsamkeit und einer reduzierten Lebensqualität. In den Befragungen der Mitarbeitenden schildern diese Angst vor einer Infektion sowohl bei sich als auch bei den Bewohnern. Infizierte Mitarbeitende in den USA äußerten Wut darüber, nicht ausreichend geschützt worden zu sein. Darüber hinaus berichteten Mitarbeitende von einer erheblichen Mehrbelastung.

Schlussfolgerung

Infolge der Pandemie und der ergriffenen Maßnahmen wurden negative psychosozialen Folgen bei Bewohnern, deren Angehörigen bzw. Besuchern und den Mitarbeitenden berichtet. Die abzuleitenden Unterstützungsbedarfe der 3 Personengruppen sind unterschiedlich und sollten bei zukünftigen Maßnahmen hinsichtlich der Pandemie stärker mitevaluiert werden.

Rectal application of argan oil improves healing of colorectal anastomosis in rats1

PURPOSE

To investigate the possible effects of argan oil on the healing of colorectal anastomoses.

METHODS

n Group 1 (sham), laparotomy was performed and the colon was mobilized. In the control (Group 2) and argan oil (Group 3) groups, colonic resection and anastomosis were applied. To the control and sham groups, 2 mL of 0.9% NaCl was administred rectally, and in the argan oil group, 2 mL/day argan oil was applied rectally for 7 days.

RESULTS

The mean bursting pressures of the argan oil and sham groups were significantly higher than the values in the control group. A significant difference was determined between the tissue hydroxyproline and prolidase levels of control group and other groups. Histopathologically, argan oil showed significant beneficial effects on colonic wound healing. In the argan oil and sham groups, the tissue malondialdehyde and fluorescent oxidation product levels were found to be lower and total sulfhydryl levels were higher than the control group.

CONCLUSIONS

The rectally administered argan oil was observed to have significantly ameliorated wound healing parameters and exerted a significant antioxidant effect. This is the first study in the literature about the beneficial effects of argan oil on colorectal anastomoses.

Oral health status and its relation with medication and dental fear in children with attention-deficit hyperactivity disorder

Objective

The objective of this study was to determine the ora-dental health and its relation with medication and dental fear in a group of Turkish children with attention-deficit hyperactivity disorder (ADHD).

Subjects and Methods

The levels of dental fear of children were determined with The Dental Subscale of Children's Fear Survey Schedule (CFSS-DS). The oral and dental health evaluation was performed. This study included a total of 117 children aged between 6 and 15 years and they were examined under two groups as "ADHD" (n = 59) and "Control" (n = 58). Ora-dental health variables were compared between the groups and were also analyzed in accordance with dental fear and medication.

Results

ADHD children and the control group exhibited similar CFSS-DS scores (15-32). No significant differences existed in df(t)/df(s), DMF(T)/DMF(S), d/D values, and presence of the white spot lesions. ADHD children's Mutans streptococci and Lactobacillus quantities were found significantly higher than the control group. The incidence of parafunctional habits of the ADHD children was also found high.

Conclusions

ADHD children that were medicated exhibited similar dental caries prevalence and periodontal health status. Although ADHD group had similar dental-periodontal health status and dental fear level with the control group and using ADHD medicines did not make a significant effect on the ora-dental health parameters, the patients should be carefully followed up because they were categorized in high caries risk groups.

Erdosteine ameliorates the harmful effects of ischemia-reperfusion injury on the liver of rats

PURPOSE

To investigate the potential protective effects of erdosteine against the harmful effects of ischemia-reperfusion injury on the liver in an experimental rat model.

METHODS

Forty rats were divided into 4 groups. In the sham group, only the hepatic pedicle was mobilized. No other manipulation or treatment was performed. In the other groups, ischemia was achieved by clamping the hepatic pedicle for 60 min. After that, 90 min reperfusion was provided. In the control group, no treatment was given. In the perioperative treatment group, 100 mg/kg erdosteine was administered 2 hours before ischemia induction. In the preoperative treatment group, 100 mg/kg/day erdosteine was administered daily for ten days before the operation. At the end of the procedures, blood and liver samples were obtained for biochemical and histopathological assessment.

RESULTS

Treatment with erdosteine ameliorated the histopathological abnormalities when compared with the control group. Furthermore, this treatment significantly decreased the serum liver function test values. It was also found that erdosteine ameliorated the oxidative stress parameters in both the perioperative and preoperative treatment groups.

CONCLUSION

The current study is the first to have shown the favorable effects of erdosteine on the harmful effects of experimental hepatic ischemia-reperfusion injury.

Mastalgia Due to Degenerative Changes of the Spine

BACKGROUND

Mastalgia is a common and enigmatic condition; the cause and optimal treatment are still inadequately defined. Cervical radiculopathy, which is the result of cervical nerve root pathology often caused by spaceoccupying lesions such as cervical disc herniation, spondylosis, or osteophytosis, is frequently encountered in physical therapy.

OBJECTIVES

The aim of the study was to evaluate the incidence of vertebral pathologies in patients with non-cyclic mastalgia and the efficacy of conservative treatment of these pathologies on relieving breast pain.

MATERIAL AND METHODS

One hundred patients were included in the study, all with breast pain continuing throughout the day and lasting at least three months. Breast and axillary physical examinations, mammographic and/or ultrasonographic evaluations were normal in all the patients. The patients' pain levels were scored using a visual analog scale (VAS). Cervical and thoracic spine magnetic resonance imaging (MRI) was performed on all the participants.

RESULTS

Among 96 patients that had pathological findings on magnetic resonance imaging (96%), 49 women had diffuse annular bulging of the cervical spine, and 47 had cervical disc protrusion. Additionally, 12 patients had thoracic disc protrusion. At the end of the three-month period, the patients who were given only conservative treatment returned for follow-up evaluations. According to the VAS scores, five patients had mild to moderate improvement, 55 showed significant improvement, and 29 achieved complete remission.

CONCLUSIONS

The authors concluded that if none of the known causes of breast pain are found in a patient, the patient should be evaluated for vertebral pathologies.

Collagen/gold nanoparticle nanocomposites: A potential skin wound healing biomaterial

In this study, nanocomposite collagen scaffolds incorporating gold nanoparticles (AuNPs) were prepared for wound healing applications. Initially, dose (<20 ppm) and size (>20 nm) of AuNPs that were not cytotoxic on HaCat keratinocytes and 3T3 fibroblasts were determined. Both collagen sponges and AuNP-incorporated nanocomposites (CS-Au) were cross-linked with glutaraldehyde (CS-X and CS-AuX). Incorporation of AuNPs into cross-linked scaffolds enhanced their stability against enzymatic degradation and increased the tensile strength. Hydrolytic degradation of CS-Au group was also less than CS after seven days. Upon confirming in vitro biocompatibility of the scaffolds with cytotoxicity assays, cell attachment and proliferation tests and the in vivo efficacy for healing of full-thickness skin wounds were investigated by applying CS-X, CS-AuX or a commercial product (Matriderm®) onto defect sites and covering with Ioban® drapes. Defects were covered only with drapes for untreated control group. The wound areas were examined with histopathological and biomechanical tests after 14 days of operation. CS-AuX group was superior to untreated control and Matriderm®; it suppressed the inflammation while significantly promoting granulation tissue formation. Inflammatory reaction against CS-AuX was milder than CS-X. Neovascularization was also higher in CS-AuX than other groups, though the result was not significant. Wound closure in CS-X (76%), CS-AuX (69%), and Matriderm® (65%) were better than untreated control (45%). CS-AuX group had the highest tensile strength (significantly higher than Matriderm®) and modulus (significantly higher than Matriderm® and CS-X), indicating a faster course of dermal healing. Further studies are also needed to investigate whether higher loading of AuNPs affects these results positively in a statistically meaningful manner. Overall, their contribution to the enhancement of degradation profiles and mechanical properties, their excellent in vitro biocompatibility, and tendency to accelerate wound healing are encouraging the use of AuNPs in collagen sponges as potent skin substitutes in the future.

Comparison of the Effects of Plateletrich Plasma Prepared in Various Forms on the Healing of Dermal Wounds in Rats

OBJECTIVE

This study was designed to evaluate the effects of 3 different forms of platelet-rich plasma (PRP) on the healing process, wound healing rate, and histopathological changes that occur during recovery of open dermal wounds.

MATERIALS AND METHODS

A 2 cm x 1 cm full-thickness skin defect was made on the backs of 40 Wistar female rats that were divided into 4 groups of 10. In group 1 (control group), the wounds were cleaned with saline; in group 2, the wounds were covered with PRP gel obtained by single centrifugation; in group 3, the wounds were covered with liquid PRP obtained by double centrifugation; and in group 4, PRP gel obtained by double centrifugation with added thrombin was applied on the dermal wounds. All treatments were applied on postoperative days 1, 4, 7, and 10.

RESULTS

In all PRP groups, the wound closure was almost complete on day 14 while the wound contraction progressed more slowly in the control group. The mean histopathological scores of epithelialization, inflammation, and fibrosis were significantly better in all PRP groups than the scores in the control group.

CONCLUSION

In conclusion, although all PRP preparations had positive effects on dermal wound healing, double centrifuged PRP topical treatments (with or without thrombin activation) are more effective than single centrifuged PRP, and double centrifugation methods should be preferred for the preparation of PRP.

The Effect of Montelukast on Liver Damage in an Experimental Obstructive Jaundice Model

Background

Montelukast is a cysteinyl-leukotriene type 1 (CysLT₁) selective receptor antagonist. In recent years, investigations have shown that montelukast possesses secondary anti-inflammatory activities and also antioxidant effects. For this reason, we aimed to determine the possible effects of montelukast on liver damage in experimental obstructive jaundice.

Methods

30 Wistar-Albino male rats were randomized and divided into three groups of 10 animals each: group I, sham-operated; group II, ligation and division of the common bile duct (BDL) followed by daily intraperitoneal injection of 1 ml of saline; group III, BDL followed by daily intraperitoneal injection of 10 mg/kg montelukast dissolved in saline. The animals were killed on postoperative day 7 by high-dose diethyl ether inhalation. Blood and liver samples were taken for examination.

Results

In this study, liver malondialdehyde (MDA) (p = 0.001), myeloperoxidase (p = 0.003), and total sulfhydryl (SH) (p = 0.009) were found to be significantly different between the BDL + montelukast and the BDL groups. Plasma total SH (p = 0.002) and MDA (p = 0.027) values were also statistically different between these groups. Statistical analyses of histological activity index scores showed that the histopathological damage in the BDL + montelukast group was significantly less than the damage in the control group (p < 0.05 for all pathological parameters).

Conclusion

According to the results of this study, montelukast showed a significant hepatoprotective effect in this experimental obstructive jaundice model, which might be due to its antioxidant and anti-inflammatory activities.

Estimation of net muscle volume in patients with muscular dystrophy using muscle CT for prospective muscle volume analysis: an observational study

OBJECTIVES

Muscle volume in patients with muscle disease is an index of disease progression. The aim of this study was to demonstrate a new method of muscle volumetry using CT of thigh muscles.

DESIGN

Observational study.

PARTICIPANTS

(1) For muscle volumetry using CT and dual-energy X-ray absorptiometry (DXA), 13 patients with muscle disease participated. (2) For prospective CT volumetry, 12 patients participated over 4 years.

PRIMARY AND SECONDARY OUTCOME MEASURES

To establish the new CT volumetry, the results of which were correlated with the muscle mass calculated from DXA (primary outcome). To show the decrease in muscle volume using our method over 4 years (secondary outcome)

METHODS

(1) Helical CT imaging of the thigh was performed. CT images were analysed by applying estimated functions, and the accumulation of outcomes resulted in muscle volumes. We refer to this method as 'net muscle volumetry'. Simultaneously, DXA was performed in these patients, and the muscle mass of the thigh was calculated with vendor-provided software. (2) To evaluate longitudinal changes in muscle volume, net muscle volumetry at the 14 cm section of the middle part of the thigh was performed repeatedly over a 4-year period.

RESULTS

(1) Volumes of the thigh muscle on one side were calculated to be 300-3400 cm(3) using CT. Muscle mass of the thigh was calculated from DXA to be 1100-5000 g. These results correspond closely, with a Pearson correlation coefficient of 0.993. (2) Thigh net muscle volumes of seven patients with gait disturbance decreased over the 4-year study period (p<0.01).

CONCLUSIONS

A method of measuring net muscle volume using CT, which was validated by muscle mass calculated from DXA, was developed. Decrements in net muscle volume over 4 years support the reliability of this method. This less arbitrary method is suitable for assessment of muscle volume in patients with muscular dystrophy.

Supersymmetry in spherical molecules and fullerenes under perpendicular magnetic fields

Methods of supersymmetric quantum mechanics are used to obtain analytical solutions for massless Dirac electrons in spherical molecules, including fullerenes, in the presence of magnetic fields. The solutions for Dirac massive charges are also obtained via the solutions of the Dirac-Weyl equation.

The Effectiveness of Porcine Dermal Collagen (Permacol(®)) on Wound Healing in the Rat Model

Porcine acellular dermal collagen (PDC), which is a biological material derived from processing porcine dermis, has already been used for urologic, gynecologic, plastic, and general surgery procedures up to now. The aim of this study is to investigate the effectiveness of PDC on wound healing as a dermal substitute in the rat model. Twenty Wistar albino rats were divided into two groups. Standard full-thickness skin defects were created on the back of the rats. In the control group (Group 1), the dressings moisturized with saline were changed daily. In the study group (Group 2), porcine dermal collagen was implanted onto each wound and fixed with 4-0 polypropylene sutures. Contraction percentages of wound areas were calculated on the third, seventh, tenth, and fourteenth days by using the planimetric program. On fourteenth day, the wound areas were excised for histopathological examination, inflammatory scoring, and evaluation of collagen deposition. The study group was superior to the control group in terms of inflammatory scoring, type I/type III collagen ratio, and wound contraction rates. Porcine dermal collagen may be used effectively and safely on full-thickness wounds as a current dermal substitute.

Effects of diosmine-hesperidine on experimental colonic anastomosis

AIM

Our goal was to determine the effects of a diosmine-hesperidine combination on wound healing in a rat model of colonic anastomosis.

MATERIALS AND METHODS

In this study, 20 Wistar Albino female rats were randomized into four experimental groups containing five rats in each group. A segment of 1 cm of colon was excised 4 cm proximally to the peritoneal reflection in all rats without carrying out any mechanical or antibacterial bowel preparation. Colonic anastomosis was performed with interrupted, inverting sutures of 6/0 polypropylene. Beginning from the first postoperative day, the rats in Groups II and IV received 100 mg/kg per day of diosmine-hesperidine via orogastic route by 4F fine feeding catheter.

RESULTS

A significant difference was detected between groups in terms of their hydroxyproline levels (p<0.05); the hydroxyproline level of Group I was significantly lower than that of the other groups while no significant difference was noted between Groups II and III.

CONCLUSION

The administration of diosmine-hesperidine increased the amount of collagen and bursting pressures at the anastomotic site and thus had favorable influences on the healing of colonic anastomosis (Tab. 1, Fig. 3, Ref. 33).

Beneficial effects of Ankaferd Blood Stopper on dermal wound healing: an experimental study

Ankaferd Blood Stopper(®) (ABS) is a folkloric medicinal plant extract used as a haemostatic agent in traditional Turkish medicine. The aim of this study was to investigate the efficacy of ABS on the healing of dermal wounds in a rat model. Twenty Wistar albino rats were divided into two groups. Standard full-thickness skin defects were created on the back of the rats. In the control group (group 1), dressings moisturised with saline were changed daily. In the study group (group 2), the wounds were cleaned daily with saline, Ankaferd solution was applied, then the wounds were covered with moisturised dressings. The contraction percentage of wound areas were calculated on the 3rd, 7th, 10th and 14th days using a planimetric programme. On day 14, the wound areas were excised for histopathological examination, inflammatory scoring and evaluation of collagen deposition. The study group was superior to the control group in terms of inflammatory scoring, type I/type III collagen ratio and wound contraction rates. ABS(®) may be used effectively and safely on full-thickness wounds as a natural product.
