Adverse-outcomes related to sarcopenia are mostly mentioned as physical disability. As the other skeletal muscles, respiratory muscles may also be affected by sarcopenia. Respiratory muscle strength is known to affect pulmonary functions. Therefore, we aimed to investigate the relations between extremity muscle strength, respiratory muscle strengths and spirometric measures in a group of male nursing home residents. Among a total of 104 male residents, residents with obstructive measures were excluded and final study population was composed of 62 residents. Mean age was 70.5 ± 6.7 years, body mass index: 27.7 ± 5.3 kg/m2 and dominant hand grip strength: 29.7 ± 6.5 kg. Hand grip strength was positively correlated with maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) (r = 0.35, p < 0.01 and r = 0.26, p < 0.05, respectively). In regression analysis, the only factor related to MIP was hand grip strength; among spirometric measures only parameter significantly related to grip strength was peak cough flow (PCF). The association of PCF with grip strength disappeared when MIP alone or "MIP and MEP" were included in the regression analysis. In the latter case, PCF was significantly associated only with MIP. We found peripheric muscle strength be associated with MIP and PCF but not with MEP or any other spirometric parameters. The relation between peripheral muscle strength and PCF was mediated by MIP. Our findings suggest that sarcopenia may affect inspiratory muscle strength earlier or more than the expiratory muscle strength. Sarcopenia may cause decrease in PCF in the elderly, which may stand for some common adverse respiratory complications.

Polypharmacy and functional dependency seem to be prevalent among female elders in our country. Nutritional status was worse than the other reported urban area of Turkey and also than among males of same region but better than among Iranian counterparts. This study illustrates geographical differences in and between the individual countries and supports the continued need for comprehensive geriatric assessment worldwide.

Functionality, comorbidities, polypharmacy, nutritional status and sarcopenia affect the prognosis of elderly excessively. These parameters are influenced by the population, living settings and age. We aimed to study these parameters in Turkish community-dwelling male elderly. We studied 274 male elderly ≥60 years of age admitted to our Geriatrics outpatient clinics. Mean age was 74.4 ± 7.1 years; 47.4% of the subjects were ≥75 years, 24.1% were ≥80 years. Mean activities-of-daily-living (ADL) and instrumental ADL (IADL) scores were 9.4 and 11.1, respectively. Patients with at least one-dependence at ADL-IADL were 22.6%-47.2%, and more than half-dependence at ADL-IADL were 2.8%-17.9%, respectively. Mean number of comorbidities were 2.6. Most common diagnosis was hypertension with 65%; mean number of drugs were 4.5; 55.3% were using ≥4 chronic drugs. Prevalences of malnutrition were 3.7%-6.9%, malnutrition risk were 23.5%-26.7% by the mini nutritional assessment test-long form and short form, respectively. Calf circumference was measured <31 cm in 10.5%. Our findings suggest that Turkish community-dwelling male elderly may have greater prevalences of functional dependence, sarcopenia but lower rates of malnutrition and similar rates of polypharmacy compared with the western developing countries and developed countries. This study emphasized the geographical differences in and/or between the individual countries highlighting the need for studies both country- and world-wide.

The aim of this study was to identify a rational strategy for the selection of multi-beam IMRT in patients with right breast cancer through the comparison of dosimetric parameters of the planning target volume (PTV) and organs at risk (OARs) using five different radiotherapy modalities. This was a retrospective study using computed tomography scans from ten patients with early-stage right breast cancer who had been treated previously. Three dimensional conformal radiotherapy (3DCRT), forward-planned IMRT (for-IMRT), inverse-planned IMRT (inv-IMRT), helical tomotherapy (HT), and volumetric-modulated arc therapy (VMAT) were planned for each patient. The plans were compared according to dose–volume histogram analysis. The most significant impact of inverse-planned multi-beam modalities for right breast cancer was the reduction of Dmax, Dmean, V53.5 and prescribed dose volume (cc) outside of the PTV (breast) (OB-V50) of the PTV. HT decreased the ipsilateral OAR volumes receiving higher doses. In exchange, HT also increased the volumes receiving low doses, which is known to lead to an increased rate of radiation-induced secondary malignancies. The heart, LAD, and contralateral doses for 3DCRT and for-IMRT were significantly lower than those for inv-IMRT, HT, and VMAT. In addition, inv-IMRT demonstrated an increase in exposed volume of heart, LAD, ipsilateral lung, and contralateral lung compared with those parameters for HT or VMAT. Although it is known to reduce cardiac toxicity with breath hold technique in left sided breast cancer, similarly it is possible for 3DCRT and for-IMRT techniques in right sided breast cancer even in free breathing.
