Pneumonia prevention in the elderly patients: the other sides

Severe aspiration pneumonia in the elderly

The global population is aging at an unprecedented rate, resulting in a growing and vulnerable elderly population in need of efficient comprehensive healthcare services that include long-term care and skilled nursing facilities. In this context, severe aspiration pneumonia, a condition that carries substantial morbidity, mortality, and financial burden, especially among elderly patients requiring admission to the intensive care unit, has attracted greater concern. Aspiration pneumonia is defined as a pulmonary infection related to aspiration or dysphagia in etiology. Prior episodes of coughing on food or liquid intake, a history of relevant underlying conditions, abnormalities on videofluoroscopy or water swallowing, and gravity-dependent shadow distribution on chest imaging are among the clues that suggest aspiration. Patients with aspiration pneumonia tend to be elderly, frail, and suffering from more comorbidities than those without this condition. Here, we comprehensively address the epidemiology, clinical characteristics, diagnosis, treatment, prevention, and prognosis of severe aspiration community-acquired pneumonia in the elderly to optimize care of this high-risk demographic, enhance outcomes, and minimize the healthcare costs associated with this illness. Emphasizing preventive measures and effective management strategies is vital in ensuring the well-being of our aging population.

Oral health status of institutionalized older adults receiving domiciliary dental care: A cross-sectional retrospective study

AIM

This study aimed to evaluate the oral health of care-dependent institutionalized older adults receiving domiciliary dental care.

METHODS AND RESULTS

Dental health records of institutionalized adults receiving regular domiciliary dental care were examined (observation period: 5 years). Relevant demographic and oral health information were extracted. Statistical analyses included descriptive and non-parametric tests (α = .05). Records of 398 nursing home residents (mean-age: 84.9 ± 6.4 years) were included. Average time spent by the residents in the institution was 2.8 ± 1.5 years. The mean number of teeth present and the overall DMF-T score was 14.7 ± 9.1 and 27.4 ± 6.2, respectively. The DMF-T score increased until the 3-year recall, with a significant increase in the number of decayed teeth (2-year: p = .013; 3-year: p = .010). An improvement in the residents' periodontal health was seen during the observation period but was not statistically significant.

CONCLUSION

The findings of this cross-sectional study confirmed that regular domiciliary dental care provision to institutionalized older adults helps maintain gingival and periodontal health. However, the incidence of dental caries might still be a problem that needs to be addressed with effective measures that improve the daily oral care provision to these older adults.

Pulmonary Diseases in Older Patients: Understanding and Addressing the Challenges

As the global population ages, pulmonary diseases among older people have emerged as a significant and growing public health concern. The increasing incidence of these conditions has led to higher rates of morbidity and mortality among older adults. This perspective study offers a thorough overview of the prevalent pulmonary diseases affecting the elderly demographic. It delves into the challenges encountered during the diagnosis and management of these conditions in older individuals, considering factors such as comorbidities, functional limitations, and medication complexities. Furthermore, innovative strategies and personalized interventions such as precision medicine, advanced therapies, telemedicine solutions, and patient-centered support systems aimed at enhancing the care provided to older individuals grappling with pulmonary disorders are thoroughly explored. By addressing the unique needs and complexities of this vulnerable population, healthcare systems can strive towards improving outcomes and enhancing the quality of life for elderly individuals affected by pulmonary diseases.

Chronic diseases spectrum and multimorbidity in elderly inpatients based on a 12-year epidemiological survey in China

BACKGROUND

The number and proportion of the elderly population have been continuously increasing in China, leading to the elevated prevalence of chronic diseases and multimorbidity, which ultimately brings heavy burden to society and families. Meanwhile, the status of multimorbidity tends to be more complex in elderly inpatients than community population. In view of the above concerns, this study was designed to investigate the health status of elderly inpatients by analyzing clinical data in Chinese People's Liberation Army (PLA) General Hospital from 2008 to 2019, including the constitution of common diseases, comorbidities, the status of multimorbidity, in-hospital death and polypharmacy among elderly inpatients, so as to better understand the diseases spectrum and multimorbidity of elderly inpatients and also to provide supporting evidence for targeted management of chronic diseases in the elderly.

METHODS

A clinical inpatients database was set up by collecting medical records of elderly inpatients from 2008 to 2019 in Chinese PLA General Hospital, focusing on diseases spectrum and characteristics of elderly inpatients. In this study, we collected data of inpatients aged ≥ 65 years old, and further analyzed the constitution of diseases, multimorbidity rates and mortality causes in the past decade. In addition, the prescriptions were also analyzed to investigate the status of polypharmacy in elderly inpatients.

RESULTS

A total of 210,169 elderly patients were hospitalized from January 1st, 2008 to December 31st, 2019. The corresponding number of hospitalizations was 290,833. The average age of the study population was 72.67 years old. Of the total population, 73,493 elderly patients were re-admitted within one year, with the re-hospitalization rate of 25.27%. Malignant tumor, hypertension, ischemic heart disease, diabetes mellitus and cerebrovascular disease were the top 5 diseases. Among the study population, the number of patients with two or more long-term health conditions was 267,259, accounting for 91.89%, with an average of 4.68 diseases. In addition, the average number of medications taken by the study population was 5.4, among which, the proportion of patients taking more than 5 types of medications accounted for 55.42%.

CONCLUSIONS

By analyzing the constitution of diseases and multimorbidity, we found that multimorbidity has turned out to be a prominent problem in elderly inpatients, greatly affecting the process of healthy aging and increasing the burden on families and society. Therefore, multidisciplinary treatment should be strengthened to make reasonable preventive and therapeutic strategies to improve the life quality of the elderly. Meanwhile, more attention should be paid to reasonable medications for elderly patients with multimorbidity to avoid preventable side effects caused by irrational medication therapy.

The risk factors and predictive modeling of mortality in patients with mental disorders combined with severe pneumonia

Background

We explored clinical characteristics and risk factors for mortality in patients with mental disorders combined with severe pneumonia and developed predictive models.

Methods

We retrospectively analyzed the data of 161 patients with mental disorders combined with severe pneumonia in the intensive care unit (ICU) of a psychiatric hospital from May 2020 to February 2023, and divided them into two groups according to whether they died or not, and analyzed their basic characteristics, laboratory results and treatments, etc. We analyzed the risk factors of patients' deaths using logistics regression, established a prediction model, and drew a dynamic nomogram based on the results of the regression analysis. Based on the results of regression analysis, a prediction model was established and a dynamic nomogram was drawn.

Results

The non-survivor group and the survivor group of patients with mental disorders combined with severe pneumonia were statistically different in terms of age, type of primary mental illness, whether or not they were intubated, whether or not they had been bedridden for a long period in the past, and the Montreal Cognitive Assessment (MoCA) scale, procalcitonin (PCT), albumin (ALB), hemoglobin (Hb), etc. Logistics regression analysis revealed the following: MoCA scale (OR = 0.932, 95% CI:0.872-0.997), age (OR = 1.077, 95%CI:1.029-1.128), PCT (OR = 1.078, 95% CI:10.006-10.155), ALB (OR = 0.971, 95%CI:0.893-1.056), Hb (OR = 0.971, 95% CI: 0.942-0.986) were statistically significant. The ROC curve showed that the model predicted patient death with an area under the curve (AUC) of 0.827 with a sensitivity of 73.4% and a specificity of 80.4%.

Conclusion

Low MoCA score, age, PCT, and low Hb are independent risk factors for death in patients with mental disorders with severe pneumonia, and the prediction model constructed using these factors showed good predictive efficacy.

Real-life impact of respiratory panel PCR assay on antibiotic prescription in geriatric acute care in the pre-COVID-19 era

OBJECTIVES

In this era of bacterial resistance, avoiding inappropriate use of antibiotic treatments is of major importance. Respiratory tract infections are frequent among older patients, and differentiating viral from bacterial infections is a challenge. The aim of our study was to evaluate the impact of recently available respiratory PCR testing on antimicrobial prescription in geriatric acute care.

METHODS

We performed a retrospective study, including all hospitalized geriatric patients who had had multiplex respiratory PCR testing prescribed from 1st October 2018 to 30th September 2019. The PCR test comprised a respiratory viral panel (RVP) and a respiratory bacterial panel (RBP). PCR testing could be prescribed at any time during hospitalization by geriatricians. Our primary endpoint was antibiotic prescription after viral multiplex PCR testing results.

RESULTS

All in all, 193 patients were included, 88 (45.6%) of whom had positive RVP, while none had positive RBP. Patients with positive RVP had significantly fewer antibiotic prescriptions following test results than patients with negative RVP (odds ratio (OR) 0.41, 95% confidence interval (CI) 0.22-0.77; p = 0.004). Among positive-RVP patients, factors associated with antibiotic continuation were presence of radiological infiltrate (OR 12.02, 95%CI 3.07-30.29), and detected Respiratory Syncytial Virus (OR 7.54, 95%CI 1.74-32.65). That said, discontinuation of antibiotic treatment seems safe.

CONCLUSION

In this population, the impact of viral detection by respiratory multiplex PCR on antibiotic therapy was low. It could be optimized by means of clearly formulated local guidelines, qualified staff and specific training by infectious disease specialists. Cost-effectiveness studies are necessary.

Effects of Dementia on Outcomes after Cervical Spine Injuries in Elderly Patients: Evaluation of 1512 Cases in a Nationwide Multicenter Study in Japan

We aimed to retrospectively investigate the demographic characteristics and short-term outcomes of traumatic cervical spine injuries in patients with dementia. We enrolled 1512 patients aged ≥ 65 years with traumatic cervical injuries registered in a multicenter study database. Patients were divided into two groups according to the presence of dementia, and 95 patients (6.3%) had dementia. Univariate analysis revealed that the dementia group comprised patients who were older and predominantly female and had lower body mass index, higher modified 5-item frailty index (mFI-5), lower pre-injury activities of daily living (ADLs), and a larger number of comorbidities than patients without dementia. Furthermore, 61 patient pairs were selected through propensity score matching with adjustments for age, sex, pre-injury ADLs, American Spinal Injury Association Impairment Scale score at the time of injury, and the administration of surgical treatment. In the univariate analysis of the matched groups, patients with dementia had significantly lower ADLs at 6 months and a higher incidence of dysphagia up to 6 months than patients without dementia. Kaplan-Meier analysis revealed that patients with dementia had a higher mortality than those without dementia until the last follow-up. Dementia was associated with poor ADLs and higher mortality rates after traumatic cervical spine injuries in elderly patients.

Modified Valsalva maneuver after burr-hole drainage of chronic subdural hematomas: A single-center cohort study

Background

Previous studies on the management of chronic subdural hematoma (cSDH) mainly focused on the risk of postoperative recurrence and measures to prevent it. In this study, we propose the use of a non-invasive postoperative treatment method, the modified Valsalva maneuver (MVM), as a means of reducing the recurrence of cSDH. This study aims to clarify the effects of MVM on functional outcomes and recurrence rates.

Methods

A prospective study was conducted at the Department of Neurosurgery, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology from November 2016 to December 2020. The study included 285 adult patients who underwent burr-hole drainage for the treatment of cSDH and received subdural drains. These patients were divided into two groups: the MVM group (n = 117) and the control group (n = 98). In the MVM group, patients received treatment with a customized MVM device for at least 10 times per hour, 12 h per day. The study's primary endpoint was the recurrence rate of SDH, while functional outcomes and morbidity 3 months after surgery were the secondary outcomes.

Results

In the current study, 9 out of 117 patients (7.7%) in the MVM group experienced a recurrence of SDH, while 19 out of 98 patients (19.4%, p < 0.05) in the HC group experienced a recurrence of SDH. Additionally, the infection rate of diseases such as pneumonia (1.7%) was significantly lower in the MVM group compared to the HC group (9.2%, p < 0.001, odds ratio (OR = 0.1). After 3 months of the surgery, 109 out of 117 patients (93.2%) in the MVM group achieved a favorable prognosis, compared to 80 out of 98 patients (81.6%) in the HC group (p = 0.008, with an OR of 2.9). Additionally, infection rate (with an OR of 0.2) and age (with an OR of 0.9) are independent predictors of a favorable prognosis at the follow-up stage.

Conclusions

The use of MVM in the postoperative management of cSDHs has been shown to be safe and effective, resulting in reduced rates of cSDH recurrence and infection following burr-hole drainage. These findings suggest that MVM treatment may lead to a more favorable prognosis at the follow-up stage.

Dental Criteria Could Alert for Malnutrition Risk and Inappropriate Choice of Food Texture in Older Subjects with Dementia: An Analytical Cross-Sectional Study

Oral health indicators are usually collected to alert for the presence of infectious diseases, but the impact of poor oral health on the nutritional status of older people with dementia is often neglected. This study aims to explore the relationship between the number of posterior dental functional units (PFUs) and the anthropometric measure of malnutrition, the mid-upper arm circumference (MUAC), in older people with dementia while controlling for other variables, and to analyze whether the number of PFUs is considered when adjusting the texture of the food provided at mealtimes. A total of 103 individuals who were 70 years or older with dementia were recruited from seven institutions. Cognitive impairment was assessed using the Mini Mental State Examination. Data were collected from medical records (sociodemographic characteristics, presence of chronic diseases, prescribed medications, results of serum albumin level), as well as questionnaires (type of feeding routes, type of food texture, supplements intake, Activity of Daily Living index), clinical examinations (MUAC), and oral health parameters (PFUs, oral dryness, oral hygiene). MUAC was the dependent outcome variable. MUAC was associated with the number of PFUs (p = 0.032); participants with PFU ≤ 4 were 7.5 times more likely to have MUAC < 21 cm than others. Other associations were found between MUAC and albumin level (OR = 12.5; p = 0.001), modified food texture (OR = 4.2; p = 0.035), and length of institutional stay (OR = 5.2; p = 0.033); however, the type of oral feeding was not significantly related to the number of PFUs (p = 0.487) so there is an inadequate correlation between food texture and oral health status. Similar to MUAC, the number of PFUs could be an oral anthropometric criterion that is recorded during routine hygiene care to alert for the risk of malnutrition and the inappropriate choice of food texture in older individuals with dementia.

Age- and sex-related differences in community-acquired pneumonia at presentation to the emergency department: a retrospective cohort study

BACKGROUND AND IMPORTANCE

Because of its associated high morbidity and mortality, early identification and treatment of community-acquired pneumonia (CAP) are essential.

OBJECTIVES

To investigate age- and sex-related differences in clinical symptoms, radiologic findings and outcomes in patients presenting to the emergency department (ED) with CAP.

DESIGN

Retrospective cohort study.

SETTING AND PARTICIPANTS

Patients admitted to one Swiss ED with radiologically confirmed CAP between 1 January 2017 and 31 December 2018.

OUTCOME MEASURES AND ANALYSIS

Primary aim was to evaluate differences in clinical and radiologic presentation of men vs. women and patients >65 years vs. <65 years with CAP. Secondary outcomes were age- and sex-related differences in terms of Pneumonia Severity Index (PSI) risk class, need for ICU referral, mechanical ventilation, in-hospital mortality, 30-day readmission and 180-day pneumonia recurrence.

MAIN RESULTS

In total 467 patients with CAP were included. 211 were women (45%). 317 were ≥65 years (68%), of which 145 were women (46%). Older patients less commonly reported chest pain (13 vs. 27%; effect size 14%; 95% CI, 0.07-0.23), fever (39 vs. 53%, effect size 14%; 95% CI, 0.05-0.24), chills (6 vs. 20%; effect size 14%; 95% CI, 0.08-0.0.214), cough (44 vs. 57%; effect size 13%; 95% CI, 0.03-0.22), headache (5 vs. 15%, effect size 10%, 95% CI, 0.04-0.17) and myalgias (5 vs. 19%; effect size 14%; 95% CI, 0.07-0.21). However, 85% of patients with no symptoms were ≥65 years. PSI was lower in women [95 (SD 31) vs. 104 (SD 31); 95% CI, -14.44 to 2.35] and sputum was more common in men (32 vs. 22%; effect size 10%; 95% CI, -0.18 to -0.02). Raw mortality was higher in elderly patients [14 vs. 3%; odds ratio (OR), 4.67; 95% CI, 1.81-12.05], whereas it was similar in men and women (11 vs. 10%; OR, 1.22; 95% CI, 0.67-2.23).

CONCLUSION

Patients, less than 65 years with CAP presenting to the ED had significantly more typical symptoms such as chest pain, fever, chills, cough, headache and myalgias than those being above 65 years. No relevant differences between men and women were found in clinical presentation, except for PSI on admission, and radiologic findings and neither age nor sex was a predictor for mortality in CAP.

The relationship between the prognostic nutritional index and new-onset pneumonia in peritoneal dialysis patients

Purpose

As an indicator of nutrition and immunity, the prognostic value of the prognostic nutritional index (PNI) has been confirmed in various diseases. However, the relationship between PNI and the incidence of pneumonia in peritoneal dialysis (PD) patients remains unknown. The purpose of this study was to investigate the relationship between PNI and new-onset pneumonia in patients undergoing PD.

Methods

Thousand two hundred and nighty eight patients were enrolled in this multicenter retrospective study from February 1, 2010, to February 28, 2020. A total of 899 patients were included in the final statistical analysis. The patients were stratified into two groups by PNI quartiles. The primary endpoint was a new-onset pneumonia event. Cox regression model analysis was used to explore the association between PNI and the first occurrence of pneumonia.

Results

During a mean follow-up of 41.43 months, 147 patients developed new-onset pneumonia. Kaplan–Meier survival curves showed a significant difference in the incidence of the first presentation of pneumonia between the two groups, that patients in the low PNI group had a higher risk of pneumonia (P = 0.016). By adjusting for demographic parameters, comorbidities, and laboratory indicators, the Cox regression model showed that the high PNI group had less risk compared to the low PNI group (HR 0.479 95% CI 0.297–0.772, P = 0.003). There were no interactions in the subgroups as follows: diabetes, hypertension, age, and sex.

Conclusions

Low PNI levels were independently associated with the first occurrence of pneumonia in PD patients. PNI was an independent predictor of new-onset pneumonia in PD patients.

Factors associated with gravity-dependent distribution on chest CT in elderly patients with community-acquired pneumonia: a retrospective observational study

Although lung involvement in aspiration pneumonia typically has a gravity-dependent distribution on chest images, which patient’s conditions contribute to its radiological pattern has not been fully elucidated. This study was designed to determine the factors associated with the gravity-dependent distribution of community-acquired pneumonia (CAP) on chest computed tomography (CT). This retrospective study included elderly patients aged ≥ 65 years with CAP who underwent chest CT within 1 week before or after admission. The factors associated with lower lobe- and posterior-predominant distributions of ground glass opacity or airspace consolidation were determined. Of the 369 patients with CAP, 348 (94%) underwent chest CT. Multivariate analyses showed that impaired consciousness, a low Barthel index of activities of daily living, and high hemoglobin levels were associated with lower lobe-predominant distribution, while male sex and impaired consciousness were associated with posterior-predominant distribution. Cerebrovascular diseases were unrelated to these distributions. While male sex, impaired consciousness, high hemoglobin levels, low albumin levels, and the number of involved lobes were associated with in-hospital mortality, gravity-dependent distributions were not. Impaired consciousness might be the most significant predictor of aspiration pneumonia; however, the gravity-dependent distribution of this disease is unlikely to affect disease prognosis.

Multi-drug resistant gram-negative bacterial pneumonia: etiology, risk factors, and drug resistance patterns

Bacterial pneumonia is one of the most serious public health issues owing to its medical and economic costs, which result in increased morbidity and mortality in people of all ages around the world. Furthermore, antimicrobial resistance has risen over time, and the advent of multi-drug resistance in GNB complicates therapy and has a detrimental impact on patient outcomes. The current review aimed to summarize bacterial pneumonia with an emphasis on gram-negative etiology, pathogenesis, risk factors, resistance mechanisms, treatment updates, and vaccine concerns to tackle the problem before it causes a serious consequence. In conclusion, the global prevalence of GNB in CAP was reported 49.7% to 83.1%, whereas in VAP patients ranged between 76.13% to 95.3%. The most commonly reported MDR-GNB causes of pneumonia were A. baumannii, K. pneumoniae, and P. aeruginosa, with A. baumannii isolated particularly in VAP patients and the elderly. In most studies, ampicillin, tetracyclines, amoxicillin-clavulanic acid, cephalosporins, and carbapenems were shown to be highly resistant. Prior MDR-GNB infection, older age, previous use of broad-spectrum antibiotics, high frequency of local antibiotic resistance, prolonged hospital stays, ICU admission, mechanical ventilation, and immunosuppression are associated with the MDR-GNB colonization. S. maltophilia was reported as a severe cause of HAP/VAP in patients with mechanically ventilated and having hematologic malignancy due to its ability of biofilm formation, site adhesion in respiratory devices, and its intrinsic and acquired drug resistance mechanisms. Effective combination therapies targeting PDR strains and drug-resistant genes, antibiofilm agents, gene-based vaccinations, and pathogen-specific lymphocytes should be developed in the future.

Associations of air pollutants with pneumonia hospital admissions in Qingdao, China: a prospective cohort study

Studies about the pneumonia morbidity effects of various air pollution exposure are still limited in China. We aimed to explore the short-term effect of air pollutants exposure on pneumonia admission and identify the vulnerable groups in Qingdao, China. From January 2015 to October 2017, a prospective cohort involving 433,032 participants across 3 counties in Qingdao were enrolled in the study. Distributed lag nonlinear model (DLNM) was applied to assess the associations between air pollutants and pneumonia hospitalizations. There were 636 cases of pneumonia, with an annual incidence density of 54.33 per 100,000 person-years (95% CI: 50.11, 58.56). A 10 μg/m³ increment of sulfur dioxide (SO₂) distributed at a 4-week lag in Qingdao was associated with increased pneumonia hospitalizations, with a risk ratio of 2.10 (95% CI: 1.06, 4.13). Subgroup analyses indicate that PM ≤ 2.5 μm in aerodynamic diameter and SO₂ showed stronger effects on pneumonia in females than males, whereas people in urban regions were more vulnerable to nitrogen dioxide and ozone (O₃) than the others. We also observed distinct acute effects and harvesting effects of SO₂ and O₃ on pneumonia in urban areas. Strategies should be taken to further reduce levels of ambient PM_2.5, SO₂, and O₃.

Total, animal, and plant protein intake and pneumonia mortality in the Japan Public Health Center-based Prospective Study

BACKGROUND

The association between total protein intake and all-cause mortality is inconsistent. Pneumonia is a major cause of death among the elderly, and the association between protein intake and pneumonia mortality warrants clarification.

OBJECTIVES

We aimed to examine the association between total, plant, and animal protein intake and pneumonia mortality in a prospective design.

METHODS

The Japan Public Health Center (JPHC)-based Prospective Study prospectively follows 83,351 participants (37,652 men and 45,699 women). Total, plant, and animal protein intakes were calculated from a validated food-frequency questionnaire. A Cox hazards model was used to calculate HRs and 95% CIs, with adjustment for confounding factors.

RESULTS

During ∼18.4 y of follow-up, 990 pneumonia deaths (634 men and 356 women) were observed. In the multivariable-adjusted model and in the model further adjusted for fatty acid intake, increase in total protein intake was marginally significantly associated with lower pneumonia mortality in women [lowest vs. highest quartile, HR (95% CI): 0.71 (0.53, 0.97), P-trend = 0.01 in the multivariable-adjusted model, and 0.70 (0.45, 1.06), P-trend = 0.05 in the fatty acid intake-adjusted model]. Total protein intake in men and animal and plant protein intake in both men and women were not significantly associated with pneumonia mortality in the fatty acid-adjusted model.

CONCLUSIONS

Although the HR in the highest quartile was not significant and further research to determine the upper limit of recommended protein intake is required, higher total protein intake was associated with lower pneumonia mortality in women.

How Do Geriatric Scores Predict 1-Year Mortality in Elderly Patients with Suspected Pneumonia?

Background: Pneumonia has an impact on long-term mortality in elderly patients. The risk factors associated with poor long-term outcomes are understated. We aimed to assess the ability of scores that evaluate patients’ comorbidities (cumulative illness rating scale—geriatric, CIRS-G), malnutrition (mini nutritional assessment, MNA) and functionality (functional independence measure, FIM) to predict 1-year mortality in a cohort of older patients having a suspicion of pneumonia. Methods: Our prospective study included consecutive patients over 65 years old and hospitalized with a suspicion of pneumonia enrolled in a monocentric cohort from May 2015 to April 2016. Each score was analysed in univariate and multivariate models and logistic regressions were used to identify contributors to 1-year mortality. Results: 200 patients were included (51% male, mean age 83.8 ± 7.7). Their 1-year mortality rate was 30%. FIM (p < 0.01), CIRS-G (p < 0.001) and MNA (p < 0.001) were strongly associated with poorer long-term outcomes in univariate analysis. CIRS-G (p < 0.05) and MNA (p < 0.05) were significant predictors of 1-year mortality in multivariate analysis. Conclusion: Long-term prognosis of patients hospitalized for pneumonia was poor and we identified that scores assessing comorbidities and malnutrition seem to be important predictors of 1-year mortality. This should be taken into account for evaluating elderly patients’ prognosis, levels and goals of care.

Improvement of Workplace Environment That Affects Motivation of Japanese Dental Hygienists

Dental hygienists are in high demand due to insufficient workforce and a lack of an effective reinstatement support system. We investigated the reasons for willingness to work by analyzing the survey results of the employment status of Japanese dental hygienists conducted by Japan Dental Hygienists’ Association. In total, we mailed 16,113 questionnaires to all members of the association (response rate 53.4%). We carried out statistical analysis to determine the specific items to improve the hygienists’ working environment. Fourteen factors of working conditions that they wish to improve were determined. Structural equation modeling showed that a path, “Reduction of work volume”, “Reduction of working hours” and “Increased number of holidays” were higher than other items. A decision analysis demonstrated that most of the respondents answered “Yes” to “Improvement in working conditions including higher salary” out of those who answered, “Strongly disagree” for “Do you feel that dental hygienist work is rewarding?”. Improving workplace environment is integral to keeping high levels of work motivation and a low turnover rate. Most of the hygienists wish for a salary raise among all the conditions. The transition from conventional work styles to non-conventional flexible working patterns is needed.

Supervised Valsalva Maneuver after Burr Hole Evacuation of Chronic Subdural Hematomas: A Prospective Cohort Study

Research on chronic subdural hematoma (cSDH) management has primarily focused on potential recurrence after surgical evacuation. Herein, we present a novel postoperative/non-invasive treatment that includes a supervised Valsalva maneuver (SVM), which may serve to reduce SDH recurrence. Accordingly, the aims of the study were to investigate the effects of SVM on SDH recurrence rates and functional outcomes. A prospective study was conducted from December 2016 until December 2019 at the Goethe University Hospital Frankfurt. Of the 204 adult patients with surgically treated cSDH who had subdural drains placed, 94 patients were assigned to the SVM group and 82 patients were assigned to the control group. The SVM was performed by having patients blow into a self-made SVM device at least two times/h for 12 h/day. The primary end-point was SDH recurrence rate, while secondary outcomes were morbidity and functional outcomes at 3 months of follow-up. SDH recurrence was observed in 16 of 94 patients (17%) in the SVM group, which was a significant reduction as compared with the control group, which had 24 of 82 patients (29.3%; p = 0.05) develop recurrent SDHs. Further, the infection rate (e.g., pneumonia) was significantly lower in the SVM group (1.1%) than in the control group (13.4%; p < 0.001; odds ratio [OR] 0.1). At the 3-month follow-up, 85 of 94 patients (90.4%) achieved favorable outcomes in the SVM group compared with 62 of 82 patients (75.6%) in the control group (p = 0.008; OR 3.0). Independent predictors for favorable outcome at follow-up were age (OR 0.9) and infection (OR 0.2). SVM appears to be safe and effective in the post-operative management of cSDHs, reducing both recurrence rates and infections after surgical evacuation, thereby resulting in favorable outcomes at follow-up.

Efficacy of High-Dose Vitamin D Supplementation as an Adjuvant Treatment on Pneumonia: Systematic Review and a Meta-Analysis of Randomized Controlled Studies

The purpose of this meta-analysis was to summarize randomized controlled trial (RCT) evidence and evaluate the efficacy and safety of vitamin D (VD) supplementation as an adjunct to antibiotics for the treatment of pneumonia. Data sources published from the inception dates up to January 2020 were searched. RCTs of VD supplementation of any duration, age, and dosing regimen type were eligible for inclusion if data on pneumonia were collected. Thirteen studies (4786 randomized participants) fulfilled eligibility criteria. VD supplementation significantly increased levels of serum 25(OH)D (mean difference = 15.97; 95% CI, 7.49-24.44; P = .002) and reduced incidence of repeat episodes of pneumonia (risk ratio [RR] = 0.68; 95% CI, 0.50-0.93; P = .02). Subgroup analysis revealed VD supplementation had more reducing effects on repeat episodes of pneumonia among participants in trials in which the population were children (RR = 0.66; 95% CI, 0.48-0.90), duration <3 months (RR = 0.55; 95% CI, 0.33-0.91), or dose of VD <300,000 IU (RR = 0.51; 95% CI, 0.29-0.89). Although our results suggested that VD supplementation had a positive effect on recovery rate of pneumonia (RR = 1.28; 95% CI, 0.94-1.74; I² = 13%), there was no statistical difference (P = .12). High-dose VD intervention may have an effect on reducing the incidence rate of repeat episodes of pneumonia by enhancing immune efficacy, although more population studies are needed to support that VD supplementation has therapeutic effects on pneumonia itself.

Oral health status and care of institutionalized elderly individuals in Lebanon

Background

Oral health of the elderly is a major public health challenge. Data on oral health and dental care of the institutionalized elderly is lacking in Lebanon.

Aims

(1) Assess the oral health of Lebanese people aged 65 years and over living in residential facilities; and (2) identify factors associated with poor oral status.

Materials and Methods

A.

sample of 526 nursing home residents aged 65 years and older was randomly selected from 46 residential facilities. Information collected were sociodemographic characteristics, degree of autonomy regarding toilet use and nutrition, presence of chronic diseases and medications, dry mouth sensation, dental brushing, access to oral health and reasons of dental visits. A structured oral examination was conducted to gather data on DMFT index, oral hygiene indices modified gingival index, and the unmet need for prosthesis. Statistical methods included bivariate and multivariate analyses.

Results

55.9% of the participants were edentates, 41.4% used partial and/or complete dentures, and the minority used dentures with good hygiene. 15% of the dentate sample reported regular tooth brushing, 7% reported to have visited the dental office in the past 12 months, and 57% presented an unmet need for prosthesis. Oral health status was significantly related to age, smoking, daily tooth brushing, and autonomy (P < 0.05). Subjects with chronic diseases and consuming medications were more likely to have xerostomia.

Conclusion

Oral health status is poor in the elderly institutionalized Lebanese population, which should promote a multidisciplinary team sharing responsibility for daily oral hygiene and access to dental treatment.
