The relationship between oral health and sleep quality in community-dwelling older adults

Introduction

The assessment of the sleep status of older adults and its relationship to oral health can help determine their well-being and quality of life. In accordance with this purpose, we aimed to evaluate the relationship between oral health and sleep quality in community-dwelling older adults in an urban area.

Materials and Methods

The data of this study were taken from the Kayseri Elderly Health Study. The study group was administered a questionnaire form and the Pittsburgh Sleep Quality Index. A specialist dentist examined the oral health conditions (dentures use; caries; deficient, filled, natural teeth numbers; periodontal health) using the Community Periodontal Index and the Oral Health Impact Profile-14 (OHIP-14-TR).

Results

One hundred forty (38.1%) of the study group were female, and 227 (61.9%) were male. When evaluated in terms of oral hygiene, there was a statistically significant difference between those with good sleep quality and poor sleep quality in terms of mechanical interventions such as using toothpaste and an inter-dental brush, and also, OHIP-14-TR was significant. In the binary logistic regression analysis, OHIP-14-TR was found to be a significant risk factor, reflecting only the subjective interpretation of the older adults in terms of oral health-related quality of life (odds ratio: 1.069, 95.0% confidence interval: 1.043-1.096).

Conclusion

This is the first epidemiologic study to examine the relationship between oral health status and sleep quality, in which many oral health indicators are evaluated together in Turkish community-dwelling older adults. OHIP-14-TR may be a useful tool to employ in sleep disorder clinics for older people.

PILE: a candidate prognostic score in cancer patients treated with immunotherapy

BACKGROUND

Although the immune checkpoint inhibitors (ICIs) became a vital part of cancer care, many patients do not respond to treatment, indicating need for biomarkers. The Pan-Immune-Inflammation Value (PIV) is a recently developed peripheral blood count-based biomarker. Herein, we evaluated a PIV-based candidate scoring system as a prognostic biomarker in ICI-treated patients.

METHODS

A total of 120 advanced cancer patients treated with anti-PD-1 or anti-PD-L1 inhibitors for any cancer type were included in this study. The PILE scoring system incorporating the PIV (< median vs. ≥ median), lactate dehydrogenase levels (normal vs. > normal) and Eastern Cooperative Oncology Group performance status (0 vs. ≥ 1) was constructed from the multivariate analyses and used for stratification. The association between overall survival (OS), progression-free survival and PILE risk category was evaluated with multivariate analysis.

RESULTS

The median follow-up was 9.62 months and the median OS of all cohort were 12.42 ± 2.75 months. Patients with higher PIV had significantly decreased OS (7.75 ± 1.64 vs. 18.63 ± 4.26 months, p = 0.037). The patients in the PILE high-risk group (PILE score 2-3) had decreased OS (18.63 ± 4.02 vs. 5.09 ± 1.23 months, HR: 2.317, 95% CI: 1.450-3.700, p < 0.001) and PFS (7.69 ± 1.30 vs. 2.69 ± 0.65 months, HR: 1.931, 95% CI: 1.263-2.954, p = 0.002) compared to PILE low-risk group (PILE score 0-1). The Harrell C-Index values were 0.65 and 0.61 for OS and PFS prediction, respectively.

CONCLUSION

In this study, we demonstrated a decreased overall survival in ICI-treated patients with a higher PILE score. If prospective studies validate our results, PILE score could be a biomarker for immunotherapy.

Clinical variations between three different causes of thrombocytopenia

Background

Thrombocytopenia is defined as the platelet count of less than 150 × 109/L and is a prominent cause of bleeding. Aplastic anemia (AA), immune thrombocytopenic purpura (ITP), and thrombotic thrombocytopenic purpura (TTP) are some of the reasons of low platelet counts.

Aims

We aimed to interpret different laboratory and clinical findings in these different reasons of thrombocytopenia.

Methods

Among patients with these disorders we assessed the performance of the ITP Bleeding Scale Assessment (ITP-BSA), which is principally designed for ITP patients.

Results

A hundred patients were included in analysis. Median platelet count at presentation was similar in all three groups. Thrombosis was seen more common in patients with TTP (20.7%) than the others (ITP; 5.6%, AA; 2.9%). In patients with TTP, sepsis (41.4%) and neurological findings (89.7%) are also more common than in the patients with ITP or AA. Bleeding was determined in all patients with AA. However, 13 patients with ITP (%36.1) and 10 patients with TTP (%34.5) had no bleeding. The most common bleeding site was skin in all three groups. There was not any gastrointestinal, lung, genitourinary, and cranial bleeding in patients with ITP. Patients with AA obtained the highest scores from the ITP-BSA. There was a significant difference between AA and the other two groups. The scores were found similar in patients with ITP and TTP (P = 0.17).

Conclusion

Clinical variations in thrombocytopenic patients may vary and assist to diagnose the cause of thrombocytopenia. The bleeding scoring systems might be helpful.

OVERTREATMENT AND HYPOGLYCEMIA PREVALENCE IN GERIATRIC PATIENTS WITH TYPE-2 DIABETES IN THE TURKISH POPULATION

OBJECTIVE

To determine the prevalence of over-treatment and hypoglycemia in Turkish type-2 diabetes patients and to identify the risk factors.

METHODS

Patients ≥ 65 years, having a minimum 5 years of type-2 diabetes, were included in the study. Patients' body mass index, mean HbA1c level, disease onset and medications related with their co-morbidities were recorded. Over-treatment is defined as the use of non-metformin therapies despite having HbA1c levels < 7%. A history of hypoglycemia episodes in the last three months and patients' home blood glucose measurements were recorded. Factors relating to hypoglycemia and over-treatment were analyzed.

RESULTS

After applying criteria, 755 patients were included in the study: 728 patients (96.4%) had at least one comorbidity. 257 patients (34%) were found to have HbA1c levels < 7%. 217 of them (84.4%) were using non-metformin therapies. 497 patients (65.8%) were using insulin. The over-treatment prevalence in the ≥ 65 years group was 28.7%. The over-treatment ratio in ≥ 80 years group was 28.2%. Hypoglycemia prevalence in the last three months was 23.3%. It was 22.7% for patients ≥ 80 years. Mean age, disease duration, body mass index, insulin usage and doses were found to be significantly different in over-treated patients compared to the others.

CONCLUSIONS

This study showed that despite recent guidelines, there is still a considerable amount of over-treated geriatric patients who are at risk of hypoglycemia and related morbidity and mortality. Insulinization rate was high. Physicians should not avoid de-intensifying the treatment of geriatric patients who have multiple co-morbidities.

Abstract P6-18-37: The efficacy and safety analysis of the treatments of everolimus and exemestane combination in 101 metastatic breast cancer patients: Real-life experience from Turkey

Background: Endocrine treatment and chemotherapy are a treatment options for patients with hormone receptor (HR) positive and HER2-negative metastatic breast cancer (MBC). However, response to first-line hormone treatment could not obtained in all patients, and even patients who havea response will eventually relapse. After disease progression, second-line hormonal treatmentoptions are used sequentially. Everolimus with exemestane has demonstrated promising activity in patients with HR-positive HER2-negative endocrine-resistant MBC with respect to the results of the BOLERO-2 study. In the present study, we aimed to evaluate the efficacy and safety of this combination in the real-life clinical setting for the unselected population in Turkey. Material and Methods: One hundred and one patients with HR-positive HER-2 negative MBC progressing after prior endocrine treatment who were treated with everolimus with exemestane were retrospectively analyzed. The tolerability and efficacy of this combination were evaluated in the unselected Turkish patients. Results: Among 101 patients, 45% of patients had visceral and %50 patients had only bone metastasis. Everolimus with exemestane treatment was administered as a second-line in 21.3% of patients, third-line in 40.4% and forth-line and later in 38.2%. The objective response rate was 24.7% (CR+PR) and stable disease was obtained in 37.7% of patients. At the median follow-up time of 13.5 months, the median progression-free survival (PFS) time and 1-year PFS were 13.8 months and 57.2%, while the median overall survival (OS) interval and 1-year OS were 40 months and 85%. The median treatment duration was 8.3 and 6.5 months for exemestane and everolimus, respectively. The most frequent reason for discontinuation of treatment were disease progression (39%). Moreover, the most common advers events (AE) causing permanent discontinuation were stomatitis (3%) and pneumonitis (3%). A total of 81 % of patients experienced at least one AE of any grade, 25% of patients at least one grade 3 or 4 AE. Due to AEs, everolimus dosage was reduced to 5 mg in 16 (15.8%) of patients. Conclusions: Our findings confirmed that the combination of everolimus with exemestane was the safe and effective treatment options for patients with HR-positive HER-2 negative MBC after second or later lines treatments.

Effect of Inulin and Lactulose on Survival of Lactobacillus AcidophilusLA-5 and Bifidobacterium Bifidum BB-02 in Acidophilus-Bifidus Yoghurt

The effect of supplementation of lactulose and inulin as prebiotics on the growth of L. acidophilusLA-5 and B. bifidumBB-02 in Acidophilus-Bifidus (AB) yoghurt and some quality parameters of the resulting products were studied. Yoghurts produced from milks with added inulin at levels of 0.5% and 1.0%, or with lactulose at levels of 0.25% and 2.5% were compared with classical yoghurt and AB yoghurt (without added prebiotics). The results showed that inulin and lactulose did not affect the growth of yoghurt starter bacteria, but stimulated the growth of B. bifidumBB-02 to a great extent. Lactulose was found to be more effective on the growth of both probiotic strains than inulin. Inulin did not stimulate the growth of L. acidophilusLA-5. The cell counts of B. bifidumBB-02 and L. acidophilusLA-5 were dependent upon concentrations of lactulose and inulin used. No significant (p< 0.05) difference between the samples were observed with regard to the pH and lactic acid values. However, lactulose or inulin added samples had lower acetaldehyde and tyrosine contents than the untreated samples.

Quality of life during chemotherapy and satisfaction with nursing care in Turkish breast cancer patients

This descriptive cross-sectional study aimed to evaluate quality of life for breast cancer patients (n = 105) undergoing chemotherapy, and to assess their satisfaction with nursing care. It also explored relationships between quality of life, satisfaction with nursing care, and demographic and disease-related characteristics. Ethics approval for this study was provided. The research was carried out between October 2011 and June 2012. Quality of life and satisfaction with nursing care were assessed using the Functional Assessment of Cancer Therapy-General Scale, the Memorial Symptom Assessment Scale and the Newcastle Satisfaction with Nursing Scale. We found that emotional well-being was the area most negatively affected, with patients reporting being afraid of death, feeling sad and being worried about their health. Patients were overall quite satisfied with the nursing care they received at the hospital. We found a positive correlation between total scores on the Newcastle Satisfaction with Nursing Scale and social and family well-being scores. Breast cancer patients have fears and concerns about their health and need support during chemotherapy for coping with negative changes in their emotional well-being, physical and functional well-being.

Low prevalence of growth hormone deficiency in Turkish patients with Hashimoto's thyroiditis

BACKGROUND

Hashimoto's Thyroiditis (HT) is frequently isolated, but may also be associated with other autoimmune disorders. Autoimmune hypophysitis can result in growth hormone deficiency (GHD). Various prevalences of GHD have been reported in HT in several different ethnic populations.

AIM

The aim of this study was assessing the prevalence of GHD in Turkish population with HT.

MATERIALS AND METHODS

Two hundred twenty-seven (208 females and 19 males, mean age 40.1 ± 10.8 years, range 18-64 years) patients with euthyroid HT were included.

RESULTS

All patients were euthyroid with or without T4 treatment (median TSH 2.2 mIU/L, range 0.2-4.2 mIU/L; median FT4 15.6 pmol/L, range 12-22 pmol/L; and median FT3 4.5 pmol/L, range 3.0-6.2 pmol/L), and median TPO-Ab was 817 IU/mL (range 63 to >3,000). One hundred and thirty-six of them were using medications including L-thyroxine (59.9 %). Insulin-like growth factor-I (IGF-I) levels of 210 patients (92.5 %) were normal. Glucagon stimulation testing in 17 subjects revealed GHD (peak <3 mcg/L) in two subjects. We then performed insulin tolerance test (ITT) to both of them as the gold standard confirmatory test. One patient had no GH response to ITT, either. Our data reveal the prevalence of GHD (based on low IGF-I and ITT result) in this particular group of Turkish HT patients as 0.4 %.

CONCLUSION

We conclude that the isolated GHD is rarely observed in HT in our population. The prevalence of GHD is 0.4 % in this particular group of Turkish HT patients suggesting that routine investigation of GHD is not mandatory.

Prognostic role of microRNA polymorphisms in advanced gastric cancer: a translational study of the Arbeitsgemeinschaft Internistische Onkologie (AIO)

BACKGROUND

To determine the prognostic role of selected microRNA (miRNA) polymorphisms in advanced gastric cancer (AGC).

PATIENTS AND METHODS

Six hundred and seventy-four AGC patients received 5-fluorouracil (F), leucovorin (L), oxaliplatin (O) or FL + cisplatin (P) or additional docetaxel (T) to FLO (FLOT) within four clinical trials. Polymorphisms of mir-26a1 (rs7372209), mir-27a (rs895819), mir-100 (rs1834306), mir-146a (rs2910164), mir-196-a2 (rs11614913), mir-219-1 (rs107822) and mir-423 (rs6505162) were genotyped. Variable selection for the final multivariate model (n = 487) was based on univariate and multivariate Cox-regression analyses with a cut-off P-value of ≤ 20%.

RESULTS

Genetic factors significantly associated with overall survival (OS) were rs7372209 (mir-26a1) variant genotypes (hazard ratio, HR 1.307 [95% confidence interval (CI) 1.031-1.656], P = 0.0272), rs895819 (mir-27a) variant genotypes (HR 1.304 [95% CI 1.031-1.650], P = 0.0270) and rs11614913 (mir-196a2) variant genotypes (HR 0.791 [95% CI 0.625-1.000], P = 0.0497). Clinical factors with significant impact on OS were Eastern Cooperative Oncology Group (ECOG) 2 performance status (HR 1.880 [95% CI 1.254-2.820], P = 0.0023), curative surgery of advanced disease (HR 0.235 [95% CI 0.123-0.449], P < 0.0001) and addition of docetaxel in locally AGC patients (HR 0.348 [95% CI 0.145-0.838], P = 0.0301). Combined analyses revealed an improved OS in patients without any unfavourable genotype of 18 months compared with 14, 12 and 10 months in patients with 1, 2 and 3 unfavourable genotypes, respectively (P = 0.0257).

CONCLUSIONS

These data suggest a significant impact of selected miRNA polymorphisms on prognosis in AGC.

Factors affecting morbidity and mortality in flail chest: comparison of anterior and lateral location

OBJECTIVE

Flail chest is most often accompanied by significant underlying pulmonary parenchymal injuries and may constitute a life-threatening thoracic injury. In this study we evaluated the treatment modalities for flail chest depending on the effect of trauma localization on mortality and morbidity.

METHODS

Between 2003 and 2008, 23 patients (20 males/3 females) were treated for flail chest. Location of the trauma in the chest wall, mechanical ventilation support, prognosis and injury severity score (ISS) were recorded for all patients. Mechanical ventilation support was given in 14 patients (60.8 %), and 12 of these 14 patients required subsequent tracheostomy. Internal fixation was used in 3 patients.

RESULTS

The major cause of flail chest was a car crash in 18 of 23 patients (76 %). Median ISS was 62.8 for all patients. The patients with flail chest who had bilateral costochondral separation (anterior chest location) (group I, n = 10) had a significantly higher ISS than those with single-side posterolateral flail chest (group II, n = 13; ISS: 70/55; P = 0.02). The need for mechanical ventilation support was also higher in the group with bilateral costochondral separation. Morbidity was higher in group I than in group II ( P = 0.198), and mortality was also significantly higher in group I ( P = 0.08). Patients with a cranial trauma and flail chest had a higher mortality (19 %) than patients with only flail chest (no mortality). The mean ISS was 75 for patients with cranial trauma and flail chest and 55.7 ( P = 0.001) for patients with only flail chest. Sepsis and subarachnoid bleeding were the major causes of mortality. The mean ISS was 54.5 for patients under the age of 55 (n = 14) whereas it was 69.4 in those aged 55 and over (n = 9; P = 0.034). Mortality in the older group was also higher (33 % versus 7 %; P = 0.02).

CONCLUSION

Early intubation and mechanical ventilation is of paramount importance in patients with flail chest. However, prolonged mechanical ventilation is associated with a poor outcome. Tracheotomy and frequent flexible bronchoscopy are an effective pulmonary toilet. Advanced age was a major risk factor for flail chest trauma mortality, together with the severity of the injury. When cranial trauma was accompanied by flail chest, mortality and morbidity rates increased. Bilateral costochondral separation also increased the risk of morbidity and the need for mechanical ventilation in patients with flail chest.

Influence of duration of total breast-feeding on bone mineral density in a Turkish population: does the priority of risk factors differ from society to society?

INTRODUCTION

Despite numerous studies on risk factors for osteoporosis the effect of breast-feeding on bone mineral density (BMD) is unclear. In this study our aim was to determine the influence of total duration of breast-feeding on BMD, and subsequent risk of osteoporosis.

METHODS

A total of 1,486 postmenopausal women over the age of 40 were included in the study. Women with diseases or who were under drug treatments known to affect bone metabolism were excluded. The BMD of the lumbar spine and femoral neck were measured by dual-energy X-ray absorptiometry technique, using either the Norland XA-26 or Lunar DPX-IQ densitometers and were transferred to standard values. Patients were placed in groups of five with respect to the duration of their breast-feeding as never, 1-12 months, 12-24 months, 24-60 months, >60 months.

RESULTS

One-way ANOVA test showed a significant difference between the lumbar spine and femoral neck BMD of these groups of women (p<0.001, p<0.001). Post hoc Bonferroni correction revealed that both the lumbar spine and femoral neck BMD results of women with longer duration of total breast-feeding were significantly lower than those of women with less duration of total breast-feeding. In subsequent analysis other potential risk factors were also considered in a multiple linear stepwise regression model. Years since menopause (p<0.001), weight (p<0.001), total duration of breast-feeding (p<0.001), and body mass index (p=0.001) were found to be the most important predictors for lumbar spine BMD; and age (p<0.001), weight (p<0.001), years since menopause (p<0.001), and total duration of breast-feeding (p<0.001) for femoral neck BMD.

CONCLUSIONS

This study showed significant associations between total duration of breast-feeding and BMD. In conclusion, total duration of breast-feeding might be an important risk factor besides age, weight, and years since menopause in postmenopausal osteoporosis.

Computed tomography in petroleum engineering research

Imaging the distribution of porosity, permeability, and fluid phases is important to understanding single and multiphase flow characteristics of porous media. X-ray computed tomography (CT) has emerged as an important and powerful tool for non-destructive imaging because it is relatively easy to apply, can offer fine spatial resolution and is adaptable to many types of experimental procedures and flow conditions. This paper gives an overview of CT technology for imaging multiphase flow in porous media, the principles behind the technology and effective experimental design. By critically reviewing prior work using this important tool, we hope to provide a better understanding of its use and a pathway to improved analysis of CT-derived data. Because of the wide variety of image processing options, they are discussed in some detail.

One-stage treatment of chronic osteomyelitis of the proximal tibia using a pedicled vascularised double-barrel fibular flap together with a muscle flap

Although segmental bone loss together with a soft-tissue defect after debridement of a chronic osteomyelitic lesion of the tibia represents a challenging problem for the reconstructive surgeon, bone management has not usually been carried out at the time of soft-tissue coverage. In a one-stage procedure, we treated a patient who had suffered from chronic osteomyelitis of the tibia for 12 years, using a pedicled vascularised double-barrel fibular flap together with a pedicled medial gastrocnemius muscle flap, immediately after radical debridement of the osteomyelitic lesion. Bony union was obtained at 4 months. Full unprotected weight-bearing for normal walking was achieved 10 months after fibular transfer. Follow-up at 2 years showed no recurrence of the osteomyelitis.
