Oral health-related quality of life in elderly: an umbrella review of systematic reviews from a multidisciplinary rehabilitation point-of-view

Background

Poor oral health is highly prevalent among elderlies and may impact quality of life of elderly people. In this scenario, oral health has been often linked to general health and chronic disorders, including distinct features of frailty. The aim of the present umbrella review of systematic reviews was to assess the scientific literature on the correlation between oral health related quality of life (OHRQoL) and elderly to present a multidisciplinary approach to these complex patients.

Methods

We performed a literature search of the databases Pub-Med/Medline, Scopus, Web of Science, and Physiotherapy Evidence Database electronic databases. Two independent reviewers performed the literature research from the inception to 25th November 2023 and screened the studies for eligibility.

Results

The search resulted in a total of 676 results eligible articles. After removal of duplicates and full-text screening, a total of 3 systematic reviews were considered to meet the inclusion criteria and were included for this review.

Conclusions

Frailty is very common in elderly such as a poor oral health. In this scenario, malnutrition and bad lifestyle habits may affect not only the determinism of many systemic non-communicable diseases but also oral health quality. Taken together, the findings of this umbrella review of systematic reviews showed a strict correlation between the frailty, typical condition of ageing people, and a poor OHRQoL. Therefore, it is mandatory to implement the oral health prevention with specific protocols of oral rehabilitation to improve the OHRQoL in elderly.

Effectiveness of Kinesiotaping and McConnell taping combined with physical exercise on gait biomechanics in patients with patellofemoral syndrome: non-randomized clinical trial

Background

Patellofemoral pain syndrome (PFPS) is a pathological condition of the knee, typical of young adults, characterized by diffuse pain in the anterior and / or medial part of the knee. We aimed to examine the effectiveness of the two types of taping in association with therapeutic exercise in relation to the biomechanical parameters, on pain and on functionality of the lower limb in patients with PFPS.

Methods

We collected data from patients treated in our outpatient's clinic with two kinds of bandage: the Kinesiotaping group (KG) and the McConnel taping group (MG). All subjects were evaluated trough an optoelectronic system, the Numeric Pain Rating Scale (NPRS), and with the Lower Extremity Functional Scale (LEFS) at baseline before applying the taping (T0), fifteen minutes after applying the bandage (T1), after four weeks of treatment (T2) without applying the bandage and three months after the end of the first treatment period with bandages and exercises (T3).

Results

Thirty-five patients (KG 16; MG 19) were included in the study. The most statistically significant changes over time in the LEFS and NPRS values have been recorded in the MG group compared to KG. The average speed and hip rotation showed a statistically significant increase between T3 and T0.

Conclusion

The application of the knee bandage for PFPS would appear to show improvement in NPRS and LEFS outcomes in both groups. Furthermore, in this study the MG evidenced better results and significant changes over time than KG.

Efficacy of ultrasound therapy combined with cryotherapy in pain management and rehabilitation in patients with Achilles tendinopathy: a retrospective observational study

Background

Achilles tendinopathy (AT) is characterized by pain, reduced performance, and swelling in and around the tendon. The aim of our study was to evaluate and compare the effects of ultrasound therapy alone or associated with cryotherapy.

Methods

We analyzed retrospectively amateur runner patients who run at least 3 times a week, with medical and ultrasound diagnosis of subacute AT of the midportion. All patients underwent 10 sessions of ultrasounds' therapy with qmd® ultrasound cryo and a therapeutic exercise with stretching and eccentric exercises. The Cryo-Ultrasound Group (CUG, 15, 8M and7/F), during the ultrasound treatment, underwent a session of cryo-ultrasound therapy. The Ultrasound Group (UD, 15, 7M and 8F) only performed ultrasound therapy.

Results

All evaluations performed show significant improvement over time in both groups. The CUG shows at T1 a greater increase in pain and function compared to the UG. Friedmann's repeated measures analysis shows that both groups improved when assessed separately over time. From the subsequent post hoc analysis, a statistically significant difference is highlighted between the values evaluated at T0 and T3.

Conclusions

The possible simultaneous delivery of the two treatment modalities, in patients suffering from tendinopathies, therefore represents a good possibility of synergistically exploiting their therapeutic actions. Future studies with a larger patient sample and longer follow-up are also needed to better evaluate the benefits of this treatment.

Gait analysis advancements: rehabilitation value and new perspectives from forensic application

The clinical and rehabilitation value of gait analysis is remarkable and indisputable and poised to grow as technological advancements unfold. This article aims to shed light on the advances in how gait is assessed, enabling those who have suffered an injury impairing their motor skills to be diagnosed more accurately and efficiently as well as to compare the hallmarks of rehabilitative and forensic gait analysis. The authors have conducted an analysis of relevant papers (published between 1967 and 2020) from a medicolegal perspective, cited in PubMed, MEDLINE, Cochrane Library, EMBASE, and available recommendations for the legal application of such techniques. Moreover, considering the use of gait analysis as a forensic tool, this study broadens the scope of research by including search engines, legal databases, and court filings (DeJure, Lexis Nexis, Justia) between 2000 and 2022. The instrumental assessment of movement (Gait Analysis) has come to constitute an essential analytical tool for the biomedical sector to objectively and accurately assess human movement and posture. The article is also aimed at elaborating differences and similarities between clinical and forensic gait analysis. When it comes to the forensic applicability of gait analysis and its evidentiary value, however, there is a pressing need for a review of its scientific basis. Therefore, it is necessary to conduct a thorough evaluation of its use in legal practice, as stressed in scientific literature and surveys. It is of utmost importance to highlight the procedural and assessment standards currently applied to forensic gait analysis, to evaluate its strengths and weaknesses, and to achieve standardized guidelines based on broad scientific consensus.

Blood Pressure Increase following COVID-19 Vaccination: A Systematic Overview and Meta-Analysis

Coronavirus disease 2019 (COVID-19) vaccines proved a strong clinical efficacy against symptomatic or moderate/severe COVID-19 and are considered the most promising approach for curbing the pandemic. However, some questions regarding the safety of COVID-19 vaccines have been recently raised. Among adverse events to vaccines and despite a lack of signal during phase III clinical trials, an increase in blood pressure (BP) after COVID-19 vaccination has been reported as a potential adverse reaction. We systematically analyze this topic and undertook a meta-analysis of available data to estimate the proportion of patients with abnormal BP or raise in BP after vaccination. Six studies entered the final analysis. Overall, studies accrued 357,387 subjects with 13,444 events of abnormal or increased BP. After exclusion of outlier studies, the pooled estimated proportion of abnormal/increased BP after vaccination was 3.20% (95% CI: 1.62-6.21). Proportions of cases of stage III hypertension or hypertensive urgencies and emergencies was 0.6% (95% CI: 0.1% to 5.1%). In conclusion, abnormal BP is not rare after COVID-19 vaccination, but the basic mechanisms of this phenomenon are still unclear and require further research.

miR-205 regulates basement membrane deposition in human prostate: implications for cancer development

The basement membrane (BM) is a layer of specialized extracellular matrix that surrounds normal prostate glands and preserves tissue integrity. Lack or discontinuity of the BM is a prerequisite for tumor cell invasion into interstitial spaces, thus favoring metastasis. Therefore, BM maintenance represents a barrier against cancer development and progression. In the study, we show that miR-205 participates in a network involving ΔNp63α, which is essential for maintenance of the BM in prostate epithelium. At the molecular level, ΔNp63α is able to enhance miR-205 transcription by binding to its promoter, whereas the microRNA can post-transcriptionally limit the amount of ΔNp63α protein, mostly by affecting ΔNp63α proteasomal degradation rather than through a canonical miRNA/target interaction. Functionally, miR-205 is able to control the deposition of laminin-332 and its receptor integrin-β4. Hence, pathological loss of miR-205, as widely observed in prostate cancer, may favor tumorigenesis by creating discontinuities in the BM. Here we demonstrate that therapeutic replacement of miR-205 in prostate cancer (PCa) cells can restore BM deposition and 3D organization into normal-like acinar structures, thus hampering cancer progression.

Transgene optimization significantly improves SIN vector titers, gp91phox expression and reconstitution of superoxide production in X-CGD cells

Gene therapy has proven to be of potential value for the correction of inherited hematopoietic disorders. However, the occurrence of severe side effects in some of the clinical trials has questioned the safety of this approach and has hampered the use of long terminal repeat-driven vectors for the treatment of a large number of patients. The development of self-inactivating (SIN) vectors with reduced genotoxicity provides an alternative to the currently used vectors. Our initial attempts to use SIN vectors for the correction of a myeloid disorder, chronic granulomatous disease, failed due to low vector titers and poor transgene expression. The optimization of the transgene cDNA (gp91(phox)) resulted in substantially increased titers and transgene expression. Most notably, transgene optimization significantly improved expression of a second cistron located downstream of gp91(phox). Thus, optimization of the transgene sequence results in higher expression levels and increased therapeutic index allowing the use of low vector copy numbers per transduced cell and weaker internal promoters.

PARP co-activates B-MYB through enhanced phosphorylation at cyclin/cdk2 sites

PARP is a multifunctional protein that can affect genome stability, transcription control, telomere length and cell death. Recently we have reported that PARP binds to and enhances B-MYB transactivating potential. B-MYB is a potentially oncogenic transcription factor involved in mammalian cell proliferation, survival and differentiation. B-MYB gene expression is growth regulated and B-MYB protein is phosphorylated during S phase by cyclin A or E/cdk2 kinase, resulting in augmented transactivating potential. Here we show that PARP induces phosphorylation of B-MYB protein at cdk2 phosphorylation sites, since a B-MYB protein with mutated cdk2 phosphorylation sites is refractory to PARP-induced phosphorylation and co-activation in mammalian cells. We propose that PARP functions as a B-MYB co-factor by promoting cyclin/cdk2-dependent B-MYB phosphorylation. These results highlight a novel role for PARP as a factor that integrates cyclin-dependent kinases signaling with gene transcription.

Direct transactivation of the anti-apoptotic gene apolipoprotein J (clusterin) by B-MYB

B-MYB is a ubiquitously expressed transcription factor involved in the regulation of cell survival, proliferation, and differentiation. In an attempt to isolate B-MYB-regulated genes that may explain the role of B-MYB in cellular processes, representational difference analysis was performed in neuroblastoma cell lines with different levels of B-MYB expression. One of the genes, the mRNA levels of which were enhanced in B-MYB expressing cells, was ApoJ/Clusterin(SGP-2/TRMP-2) (ApoJ/Clusterin), previously implicated in regulation of apoptosis and tumor progression. Here we show that the human ApoJ/Clusterin gene contains a Myb binding site in its 5' flanking region, which interacts with bacterially synthesized B-MYB protein and mediates B-MYB-dependent transactivation of the ApoJ/Clusterin promoter in transient transfection assays. Endogenous ApoJ/Clusterin expression is induced in mammalian cell lines following transient transfection of a B-MYB cDNA. Blockage of secreted clusterin by a monoclonal antibody results in increased apoptosis of neuroblastoma cells exposed to the chemotherapeutic drug doxorubicin. Thus, activation of ApoJ/Clusterin by B-MYB may be an important step in the regulation of apoptosis in normal and diseased cells.

Urocortin protects against ischemic and reperfusion injury via a MAPK-dependent pathway

Urocortin (UCN) is a peptide related to hypothalamic corticotrophin-releasing hormone and binds with high affinity to corticotrophin-releasing hormone receptor-2beta, which is expressed in the heart. In this study, we report that UCN prevented cell death when administered to primary cardiac myocyte cultures both prior to simulated hypoxia/ischemia and at the point of reoxygenation after simulated hypoxia/ischemia. UCN-mediated cell survival was measured by trypan blue exclusion, 3'-OH end labeling of DNA (TUNEL), annexin V, and fluorescence-activated cell sorting. To explore the mechanisms that could be responsible for this effect, we investigated the involvement of MAPK-dependent pathways. UCN caused rapid phosphorylation of ERK1/2-p42/44, and PD98059, which blocks the MEK1-ERK1/2-p42/44 cascade, also inhibited the survival-promoting effect of UCN. Most important, UCN reduced damage in isolated rat hearts ex vivo subjected to regional ischemia/reperfusion, with the protective effect being observed when UCN was given either prior to ischemia or at the time of reperfusion after ischemia. This suggests a novel function of UCN as a cardioprotective agent that could act when given after ischemia, at reperfusion.

Quantitative assessment of cardiac myocyte apoptosis in tissue sections using the fluorescence-based tunel technique enhanced with counterstains

Apoptosis is a distinct form of cell death, induced, for example, by ischaemia/reperfusion injury, that results in characteristic alterations in cell morphology and fate. In tissue sections, the most commonly used technique to detect apoptosis is terminal deoxynucleotidyl transferase mediated nick end labelling (TUNEL) staining which labels the ends of DNA strand breaks characteristic of the apoptotic process. However, without the employment of additional staining, TUNEL is only a qualitative procedure that gives no information about the proportion of negative cells nor the cell type undergoing apoptosis. We have utilised propidium iodide (PI) as a counterstain to visualise TUNEL negative nuclei together with anti-desmin antibody in order to assess quantitatively apoptosis in specific cell types. The procedure has been evaluated in tissue sections from isolated perfused rat hearts subjected to ischaemia and reperfusion. Hearts were cross-sectioned into four 2.5 mm thick slices which were fixed in 4% formaldehyde and embedded in paraffin. Serial sections (5 microns) were cut, dewaxed and pretreated by incubation with trypsin at 37 degrees C for 30 min. After the employment of the TUNEL assay, sections were labelled with anti-desmin antibody, counterstained with PI and finally examined by confocal fluorescent microscopy. Apoptosis was not seen in sections from hearts subjected to ischaemia alone nor in control hearts. After 35 min of ischaemia the percentages of TUNEL positive cells were very low both in myocytes (0.1%) and in non-myocytes (0.3%). In ischaemic-reperfused hearts, the number of TUNEL positive cells was only significantly higher in vascular cells (44+/-5%) and cardiac myocytes (6+/-2%). This simple method therefore allows quantification of apoptosis in myocytic and non-myocytic cells in tissue sections. Use of alternative immunohistochemical markers would permit adaptation of the method to the quantitative assessment of apoptosis in other tissues.

Sequential identification of apoptotic and necrotic cells on individual cytospin preparations

Here, we describe a simple methodology which allows the consecutive differentiation of apoptotic and necrotic cells on the same cytospin preparation of fresh and cultured cells. In this methodology, necrotic cells are initially identified on the cytospin preparations using trypan blue followed by the identification of in situ DNA fragmentation using the TUNEL assay. Identification of trypan blue and TUNEL positive cells in the same section permits the simultaneous assessment of necrotic and apoptotic cells.

Machine operator's lung. A hypersensitivity pneumonitis disorder associated with exposure to metalworking fluid aerosols

Six auto parts manufacturing workers were referred for evaluation of a 6-week history of work-related dyspnea, cough, and fatigue. Two workers also reported fever and weight loss. All six worked in a machining area where a waterbased metalworking fluid was used and recirculated under high pressure, thereby creating an aerosol. Chest radiographs revealed pulmonary interstitial infiltrates in four workers. Lung function tests showed that four workers had decreased diffusing capacity. After removal from the work area, all workers recovered. The metalworking fluid was cultured for bacteria and fungi. Isolates from broth cultures were sonicated to obtain antigen extracts. Serum precipitins to one or more of the microbial isolates were identified in all six workers but not in eight of nine nonexposed control subjects. The most frequent precipitin response (six of six workers) was against antigens of Pseudomonas fluorescens, which was cultured from the metalworking fluid. In all workers, precipitins to at least one other cultured organism were detected; these included Aspergillus niger, Staphylococcus capitas, an acid-fast Rhodococcus sp, and Bacillus pumilus. This represents the first report of hypersensitivity pneumonitis associated with industrial exposure to aerosolized metalworking fluid. Observed precipitin responses to a variety of microbial contaminants in metalworking fluid strongly suggest a causative role for microbial antigens in the induction and elicitation of this manifestation of hypersensitivity pneumonitis.

Comparative study with piroxicam and ibuprofen versus placebo in the supportive treatment of minor sports injuries

Piroxicam (20 mg o.d.), ibuprofen (200 mg t.i.d.) or placebo were added to the conventional treatment in three different groups of professional athletes with soft-tissue injuries. The piroxicam-treated group showed, with a once-a-day only administration, a statistically significant better improvement of various subjective and objective signs of functional damage.
