RESUMO

BACKGROUND: Most of the research focused on mortality and neglected functional outcome in older patients admitted to intensive care unit (ICU). AIMS: The aim of this study is evaluating functional outcome in older patients admitted to ICU. METHODS: A cross-sectional study of 203 elderly patients admitted to Geriatric ICU in Ain Shams University Hospitals and followed for 90 days after ICU discharge to track their functional level and other adverse outcomes. RESULTS: The mean age for the cohort was 72.6 ± 8.8. Seventy-three patients survived after 3 months (36%). Only 42 patients out of 73 survivors maintained the same level of functions (58%). Factors related to functional decline were Charlson Comorbidity Index and infections acquired within 3 months after discharge. ICU scores, like APACHE and SAPS II scores were not effective in predicting functional outcomes. CONCLUSIONS: Comorbidity burden and infections acquired within 3 months after discharge are important determinants of long-term functional level after ICU admission.

RESUMO

BACKGROUND: Despite decades of research evaluating different predictive strategies to identify persons at risk for falls, nutritional issues have received little attention. Malnutrition leads to weight loss associated with muscle weakness and consequently increases the risk of falls. AIMS: The current study assessed the association between nutritional state and fall risk scores in a geriatric in-patient unit in Ain Shams University Hospital, Cairo, Egypt. METHODS: A cross-sectional study was conducted to assess the nutritional state of 190 older inpatients using a short form of the Mini-Nutritional Assessment (MNA-SF), and the risk of falls was assessed using the Morse Fall Scale (MFS), Johns Hopkins fall risk assessment tool (JH-FRAT), Schmid Fall Risk Assessment Tool (Schmid-FRAT), Hendrich II Fall Risk Model (HII-FRM) and Functional Assessment Instrument (FAI). The generalised linear models (GLM) and odds ratio (OR) were calculated to test the nutritional status as a risk factor for falls. RESULTS: Malnutrition was significantly associated with high fall risk as assessed by MFS and HII-FRM (OR = 2.833, 95% CI 1.358-5.913, P = 0.006; OR = 3.477, 95% CI 1.822-6.636, P < 0.001), with the highest OR for JH-FRAT (OR = 5.455, 95% CI 1.548-19.214, P = 0.008). After adjusting for age, the adjusted Charlson Comorbidity Index (ACCI), number of fall risk-increasing drugs (FRIDs), risk of malnutrition or malnourished were significantly associated with high fall risk as assessed by MFS (OR = 2.761, 95% CI 1.306-5.836, P = 0.008), JH-FRAT (OR = 4.938, 95% CI 1.368-17.828, P = 0.015), and HII-FRM (OR = 3.486, 95% CI 1.783-6.815, P < 0.001). CONCLUSIONS: This study demonstrated a significant association between malnutrition and fall risk assessment scores, especially JH-FRAT, in hospitalised older patients.

RESUMO

Transcranial Doppler (TCD) screening is an established tool to identify children with sickle cell disease at high risk of stroke. Our objective was to study TCD velocities among sickle cell disease patients while in a steady state. This cross-sectional study included 78 steady state sickle cell disease patients [31 Hb SS (ßS/ßS) (sickle cell anemia), 47 Hb S/ß-thalassemia (HBB: c.20A>T/ß-thal)], attending the Pediatric Hematology Clinic at Cairo University Children's Hospital, Cairo, Egypt. All patients underwent TCD velocity assessment as per the Stroke Prevention Trial in Sickle Cell Anemia (STOP) protocol. In our cohort, TCD velocities were comparable among Hb S/ß-thal vs. SS patients. Hemolysis indicators correlated significantly to TCD velocities in Hb S/ß-thal patients; positive correlation was found between total bilirubin level and right middle cerebral artery (MCA) and right distal internal carotid artery (dICA) TCD velocities (r = 0.428, p = 0.00, r = 0.360, p = 0.01), respectively as well as between reticulocyte count and right MCA, right dICA and right anterior cerebral artery (ACA) TCD velocities (r = 0.424, p = 0.01), (r = 0.40, p = 0.00), (r = 0.303, p = 0.04), respectively. On the other hand, statistically significant negative correlations were found between hemoglobin (Hb) level and right ACA, right dICA TCD velocities (r = -0.290, p = 0.05), (r = -0.324, p = 0.03). Although Hb F is considered an ameliorating factor for disease severity; hemolysis stands as an indicator of risk for TCD velocity elevation, and in turn, risk for stroke among sickle cell disease patients.

RESUMO

BACKGROUND: This study is comparing thermal radiofrequency ablation (TRFA) of the thoracic dorsal root ganglia (TDRG) guided by Xper CT and fluoroscopy with the standard fluoroscopy. METHODS: This randomized clinical trial included 78 patients suffering from chronic refractory pain due to chest malignancies randomly allocated into one of two groups according to guidance of TRFA of TDRG. In CT guided group (n = 40) TRFA was done under integrated Xper CT-scan and fluoroscopy guidance, while it was done under fluoroscopy guidance only in standard group (n = 38). The primary outcome was pain intensity measured by visual analog scale (VAS) score, functional improvement and consumption of analgesics. The secondary outcome measures were patient global impression of changes (PGIC) and adverse effects. RESULTS: VAS scores decreased in the two groups compared to baseline values (p < 0.001) and were lower in CT guided group up to 12 weeks. Pregabalin and oxycodone consumption was higher in the standard group at 1, 4 and 12 weeks (p < 0.001). Functional improvement showed near significant difference between the two groups (P = 0.06 at week 1, 0.07 at week 4 respectively) while the difference was statistically significant at week 12 (P = 0.04). PGIC showed near significant difference only at week 1 (P = 0.07) while the per-patient adverse events were lower in CT guided group (p = 0.027). CONCLUSIONS: Integrated modality guidance with Xper CT-scan and fluoroscopy together with suprapedicular inferior transforaminal approach may improve efficacy and safety of TRFA of TDRG for the treatment of intractable chest pain in cancer patients. TRIAL REGISTRATION: The study was retrospectively registered at clinicaltrials.gov on 04/22/2018 (Registration No.: NCT03533413).

RESUMO

We aimed to compare the performance of seven risk screening tools for detecting elderly Egyptian women with osteoporosis and to modify the tool with the best performance to increase the efficiency of referral for bone mineral density (BMD) testing. There are few studies about the epidemiology of osteoporosis in Egypt, in addition, there was no study done before to evaluate the performance of these seven screening tools in a large sample size. This aims to help clinicians restrict the use of DXA scan for those patients defined as "high risk" for osteoporosis which can substantially reduce the cost for the community and the patients, especially in developing countries. We conducted a cross-sectional study on 681 elderly women for measurement of BMD using DXA scans. The performance of the Simple Calculated Osteoporosis Risk Estimation (SCORE) was superior to other indices with the highest sensitivity and specificity. The newly modified SCORE tool at cutoff point ≥1 is a simple easy tool and shows good sensitivity (up to 94%) and acceptable specificity (up to 46.7%) in detecting osteoporosis in elderly women with fewer items and easier calculation.

RESUMO

AIM: Doppler ultrasonography can be used to assess the progression of vascular (arterial sclerosis) and parenchymal (glomerular sclerosis and crescents) renal damage. The aim of this study was to evaluate the significance of some sonographic and Doppler parameters as non-invasive markers of glomerular filtration rate (GFR) and renal histopathological damage in children. METHODS: A cohort of 84 children were enrolled in a case-control study (42 with CKD stages 2-5 and 42 healthy children). GFR was assessed using new improved equation using serum creatinine and cystatin C. Sonar guided renal specimen was obtained and evaluated for the severity of global sclerosis (GS), segmental sclerosis (SS), tubular atrophy (TA), interstitial fibrosis (IF), arterial sclerosis (AS) and arteriolar hyalinosis (AH). The following sonographic and Doppler parameters were assessed in both patients and control group: resistivity index (RI), pulsatility index (PI), atrophic index (AI), mean renal volume, mean renal density, time average velocity (TAV) and body surface area related volume perfusion (BSARVP). RESULTS: There was significant difference in renal density (P < 0.001), RI (P < 0.001), PI (P = 0.021), TAV (P < 0.001) and BSARVP (P < 0.001) between patients and control group. The cutoff value of RI was 63.5% (sensitivity 83% and specificity 64%). Multivariate analysis revealed that renal density and RI were significant predictors of worsening of estimated GFR (eGFR) in CKD patients. CONCLUSION: Any increase in the RI and PI values must arouse alarm to the possibility of advancing renal damage. Moreover, RI and PI could fairly predict the degree of glomerular sclerosis and interstitial fibrosis.

RESUMO

PURPOSE: To evaluate the difference in cerebral blood flow in neonates with and without extreme unconjugated hyperbilirubinemia. METHODS: Transcranial Doppler parameters of 26 full term newborns with extreme unconjugated hyperbilirubinemia (UCH) were compared to 13 postnatal age and sex matched normal healthy neonates serving as controls. Resistance index (RI), pulsatility index (PI) and peak systolic velocity (PSV) were measured in the middle cerebral, internal carotid and posterior cerebral arteries on both sides by transcranial color Doppler ultrasound. RESULTS: An increase in cerebral blood flow (decreased RI, PI and increased PSV) was observed in the extreme unconjugated hyperbilirubinemia (UCH) group. There was positive correlation between total serum bilirubin level and peak systolic velocity and vice versa with resistivity and pulsatility indices. Eight neonates developed clinical features of acute bilirubin encephalopathy and showed significantly increased peak systolic velocity in the right middle cerebral artery compared to those with normal outcome. Resistivity index and pulsatility index were lower in patients managed by exchange transfusion compared to those managed with phototherapy. CONCLUSION: An increase in cerebral blood flow was observed in neonates with UCH compared to those without hyperbilirubinemia. By assessing the cerebral blood flow velocity, resistivity index (RI), and pulsatility index (PI) of particular intracranial arteries, the transcranial Doppler can identify the at-risk neonates, for development of neurological affliction in extreme unconjugated hyperbilirubinemia.

RESUMO

Purpose: This study aimed to analyze the effect of body mass factors (BMFs) on setup errors in gynecologic tumors, and whether the planned tumor volumes (PTVs) are adequate for obese patients. Methods: This was a retrospective study of 46 consecutive female patients with gynecologic tumors who were treated with volumetric modulated arc therapy. Setup accuracy was verified using daily cone beam computed tomography. Accuracy was determined for each fraction by testing 2 different PTVs (cutoff I = ≤0.7 cm; cutoff II = ≤1.0 cm). A pooled analysis was conducted to test the association between accuracy levels (within vs beyond PTV) and the mean and variance of body mass index (BMI), umbilical (UC), and hip circumference (HC). A receiver operating characteristics curve analysis was carried out to test the sensitivity of BMI, UC, and HC in predicting inaccurate setup. Results: A significant association between BMFs and level of accuracy was observed in the lateral and vertical directions, but not in the longitudinal direction. In the lateral direction, inaccurate setups were associated with a greater BMI (mean difference: ∼3.50 kg/m2; P = .001), UC (∼10 cm), and HC (∼8 cm) compared with accurate setups (P < .001). With respect to the vertical direction, inaccurate setups (>0.7 cm margin [cutoff I]) were associated with a greater BMI (mean difference = 7.4 kg/m2; P = .001), UC (5.3 cm; P < .001), and HC (16.0 cm; P < .001) with reference to accurate setups. The receiver operating characteristics curve analysis showed that a BMI >31.4 kg/m2 was predictive for inaccurate setup in the vertical direction with 90.0% sensitivity with respect to cutoff I. Furthermore, a BMI >30.3 kg/m2 was predictive for inaccurate setup in the lateral direction with 92.5% sensitivity with respect to cutoff II. Conclusions: The accuracy of radiation therapy setups for gynecologic tumors is highly sensitive to patients' BMI, notably in the lateral and vertical directions. We suggest that daily cone beam computed tomography should be applied on patients with a BMI >30.3 kg/m2, using customized protocols that are lower in dose and comparable in image quality.

RESUMO

Objective: To assess the perceived risks and impact of the COVID-19 outbreak on radiation therapists in Saudi Arabia. Methods: A questionnaire was distributed to all radiation therapists in the country. The questionnaire contained questions about demographic characteristics, the extent of the pandemic's impact on hospital resources, risk perception, work-life, leadership, and immediate supervision. The questionnaire's reliability was assessed using Cronbach's alpha; >0.7 was considered adequate. Results: Out of the 127 registered radiation therapists, 77 (60.6%) responded; 49 (63.6%) females; and 28 (36.4%) males. The mean age was 36.8 ± 12.5 years. Nine (12%) of the participants had a past experience with pandemics or epidemics. Further, 46 (59.7%) respondents correctly identified the mode of transmission of COVID-19. Approximately, 69% of the respondents perceived COVID-19 as more than a minor risk to their families and 63% to themselves. COVID-19 had an overall negative impact on work at the personal and organizational levels. However, there was a positive attitude toward organizational management during the pandemic in general; positive responses ranged from 66.2% to 82.4%. Ninety-two percent considered protective resources and 70% considered the availability of supportive staff to be adequate. Demographic characteristics were not significantly associated with the perceived risk. Conclusions: Despite the high perception of risk and negative impact on their work, radiation therapists conveyed a positive overall perception regarding resource availability, supervision, and leadership. Efforts should be made to improve their knowledge and appreciate their efforts.

RESUMO

OBJECTIVES: To assess setup reproducibility of low kneefix with feetfix (LKF-FF) system and its operator-reported convenience by reference to low dual leg positioner (LDLP), among patients treated with pelvic radiotherapy. METHODS: A retrospective controlled trial was carried out at the radiotherapy unit. It included patients who underwent radical radiotherapy to the pelvis using VMAT, and who benefitted from LDLP (N = 30) or LKF-FF (N = 30) immobilization system. Average absolute shifts (AAS) and total vector errors (TVE) were computed and compared between the two systems, using translational (lateral, longitudinal and vertical) and rotational (X, Y and Z planes) directions. Accuracy rates were computed on pooled data including 1529 VMAT images, 819 in LDLP and 710 in LKF-FF groups, using different cutoffs. Radiotherapists' subjective assessment of the device's ease of setup, handling, cleaning, and storage, and patient comfort was carried out comparatively between the two devices. RESULTS: No statistically significant difference was observed between the two systems in systematic settings, while LKF-FF outperformed LDLP in random settings; notably in vertical translation and X and Z rotational shifts. Analysis of TVEs showed significant decrease in rotational TVE in LKF-FF group (mean=1.38° versus 2.38, p = 0.003) by reference to LDLP, respectively; however, both systems had comparable translational TVE (p = 0.590). In pooled analysis, LKF-FF enabled an overall increase in setup accuracy rates in rotational directions by up to 15% and 19% at ±1° and ±2° accuracy levels, respectively (p<0.05). Subjective assessments showed that the two immobilization systems were comparable regarding all investigated dimensions; however, the overall radiotherapists' preference leaned toward LDLP. CONCLUSION: The newly implemented LKF-FF system outperformed LDLP in terms of setup reproducibility, notably in rotational directions, where it enhanced setup accuracy rates by up to 19%. Long-term use of LKF-FF may improve the users' satisfaction.

RESUMO

We aimed to test the hypothesis that a lung ultrasound severity score (LUS) and assessment of left ventricular eccentricity index of the interventricular septum (LVEI) by focused heart ultrasound can predict extubation success in mechanically ventilated infants. We conducted a prospective study on premature infants less than 34 weeks' of gestation. LUS was performed on postnatal Days 3 and 7 by an investigator who was masked to infants' ventilator parameters. LVEI and pulmonary artery pressure (PAP) were measured at postnatal Day 3. A receiver operator curve was constructed to assess the ability to predict extubation success. Spearman correlation was performed between LVEI and PAP. A total of 104 studies were performed to 66 infants; of them 39 had mild and 65 had moderate-severe lung disease. LUS predicted extubation success with a sensitivity and a specificity of 91% and 69%, respectively. Area under the curve was 0.83 (CI: 0.75-0.91). LVEI did not differ between infants that succeeded and failed extubation. It correlated with PAP during systole (r = .66). We conclude that LUS predicts extubation success in mechanically ventilated preterm infants whereas LVEI correlates with high PAP.

RESUMO

Radioactive plaque brachytherapy has an established role for selected patients with retinoblastoma. Newer non-invasive radiotherapy techniques such as stereotactic conformal radiotherapy (SCR) that uses highly accurate positioning to deliver treatment with small beams may be an interesting alternative to brachytherapy. We report a case treated with SCR and compare the dosimetry with that achievable with brachytherapy. With advantages and disadvantages to both, SCR should more often be considered in the management of RB because of the more homogeneous dose within the target volume and similar or lower doses to surrounding normal tissues.

RESUMO

INTRODUCTION: The population is aging in Egypt and hence functional limitation is increasing. Thus finding the best measures for its detection is mandated. OBJECTIVES: The aim of this study was to assess whether Katz ADL (activities of daily living) and Lawton IADL (instrumental activities of daily living) were suitable measures to represent the functional abilities of older Egyptians of both genders during hospital admission and to determine the dimensionality of both tools. METHODS: Functional status was assessed during hospital admission as a part of the comprehensive geriatric assessment for 786 older patients (aged 60 years and older). 150 of them were randomly interviewed to collect data regarding the difficulty during each task of Katz ADL and Lawton IADL performance, unnecessary and unmet needed assistance, barriers to get needed assistance and the type of care providers. RESULTS: The prevalence of ADL and IADL dependency was 61.80 % and 85.87 %, respectively. Functional limitation in both scales was found to be significantly associated with increasing age, marital status other than married, cognitive impairment. Both scales showed a bi-dimensional factor structure, removing continence from Katz ADL resulted in a uni-dimensional scale. Females were more dependent than males in all tasks except household tasks of IADL. CONCLUSIONS: Katz ADL and Lawton IADL did not capture the actual dependency level among older Egyptians. The household tasks in Lawton IADL and continence in Katz ADL mislabeled dependency in the studied sample.

RESUMO

BACKGROUND AND AIM OF WORK: Sickle cell disease (SCD) is an inherited disease of the beta globin gene. The ßS globin gene haplotypes are Senegal, Benin, Bantu, Cameroon, Arab-Indian and atypical haplotypes. In SCD, stroke is a life-threatening event in both adults and children. In light of paucity of studies on ßS globin gene haplotypes in Egypt, we aimed to determine ßS globin gene haplotypes in children with SCD and study their impact on stroke risk. METHODS: Fifty-two SCD patients were included in the study, they were 26 males and 26 females with age range from 3 to 18 years old. The PCR-RFLP technique was used for the determination of ßS globin gene haplotypes. Transcranial Doppler (TCD) was done to identify patients at risk of stroke. RESULTS: Benin/Benin was the most prevalent haplotype detected in 50% followed by Benin/Bantu in 30.8% of studied patients. TCD study showed that 14/52 (26.9%) patients had abnormally high TCD flow velocities (TCD velocities ≥170 cm/s) and thus considered high stroke risk group, whereas 38/52 (73.1%) patients had TCD flow velocities <170 cm/s and are considered low stroke risk group. Stroke risk was not found to be associated with ßS globin gene haplotype (p = .532). CONCLUSION: This study provides a relevant contribution to our understanding of the anthropological and historical background of the population in Egypt where Benin haplotype is the commonest ßS globin gene haplotype and homozygous Benin/Benin is associated with higher stroke risk than other haplotypes.

RESUMO

INTRODUCTION: Familial Mediterranean fever (FMF) is an autosomal recessive disease. It is characterized by recurrent crises of fever and serosal inflammation. Although FMF patients are symptom free in between attacks, subclinical inflammation continues during the attack-free period. Such patients with inflammatory status have an increased risk of atherosclerotic cardiovascular complications. We attempted to elucidate the role of arterial wall thickening as a predictor of early atherosclerosis in children affected by FMF and to clarify the links between carotid intima media thickness and the markers of subclinical inflammation serum amyloid A (SAA), erythrocyte sedimentation rate (ESR), neutrophil-to-lymphocyte ratio (NLR) and platelet lymphocyte ratio (PLR). MATERIAL AND METHODS: It is a case control study. The study comprised 45 Egyptian children diagnosed with FMF and 45 healthy children of matched age and sex who served as controls, without family history or clinical manifestations suggestive of FMF. Laboratory investigations included complete blood count, NLR, PLR, ESR, C-reactive protein and lipid profile. Serum amyloid A levels were determined in both groups using enzyme linked immunosorbent assay. Assessment of the common carotid artery intima media thickness (CIMT) in the FMF patients was carried out. RESULTS: The level of SAA was significantly higher in patients than the control subjects with a mean value of 38.30 ng/ml and 23.43 ng/ml respectively (p < 0.001). Our patients showed significantly higher PLR when compared to controls (p < 0.001). The mean right and left carotid intima media thickness in patient and control groups showed a highly significant difference (p = 0.005 and 0.036 respectively). CONCLUSIONS: The mean carotid intima media thickness is higher in cases than the control group. Hence carotid intima media thickness may be used as a tool in the prediction of any atherosclerotic burden in those children.

RESUMO

OBJECTIVE: To evaluate the role of Doppler ultrasonography in the assessment of splanchnic circulation's hemodynamic changes in septic preterms at risk of necrotizing enterocolitis. METHODS: A total of 51 septic preterms were divided into two groups: 25 preterms with clinical signs of necrotizing enterocolitis (NEC) and 26 preterms with no clinical signs of NEC. Both groups were assessed with Doppler ultrasonography of the celiac and superior mesenteric arteries, and each septic preterm's peak systolic velocity (PSV), end-diastolic velocity (EDV), resistivity index (RI), and pulsatility index (PI) was calculated and recorded. RESULTS: These included a statistically significant lower PSV (p: 0.001) and a lower EDV (p: 0.001) in the superior mesenteric artery in the septic group with clinical signs of NEC in comparison with the septic group with no clinical signs of NEC. A statistically significant (p < 0.001) higher PSV celiac (CA)/PSV superior mesenteric (SMA) ratio was found for the group of septic preterms with clinical signs of NEC when compared to the other group. CONCLUSION: The study results showed that Doppler ultrasonography of the splanchnic circulation can be a tool for the early identification of NEC cases among septic preterms.

RESUMO

The relationship between chronic hemolysis with subsequent iron overload, inflammation, and premature atherosclerosis has been documented in hemolytic anemias, particularly ß-thalassemia. However, no such relationship has been established in sickle cell disease (SCD). We sought to evaluate SCD as a risk factor for early vascular insult by measuring carotid intima-media thickness (CIMT) and plasma chitotriosidase and to assess the role of the latter as a potential quantitative indicator of vascular inflammation and atherogenesis. Thirty SCD pediatric patients (3-18 years) and 30 matched controls were enrolled. Full clinical history, with hematological and biochemical parameters, was evaluated. CIMT and chitotriosidase activity were also assessed for all study participants. CIMT values were significantly higher in SCD patients (median 0.42; range 0.32-0.6 mm) compared to controls (0.36; 0.34-0.45 mm), P = 0.03. CIMT correlated positively with age (r = 0.460, P = 0.011), and total number of vascular incidents necessitating hospital admission (r = 0.439, P = 0.015). Similarly, chitotriosidase activity was significantly higher among SCD patients (median 59.6; range 7.3-512 nmol/ml plasma/h) compared to controls (32.7; 6.8-63.1 nmol/ml plasma/h), P < 0.001, and showed a positive correlation with serum ferritin (r = 0.517, P = 0.003) and CIMT (r = 0.535, P = 0.002). SCD children are at risk of developing premature atherogenic changes. Plasma chitotriosidase and CIMT may represent useful predictors of these changes.

RESUMO

BACKGROUND & AIMS: The Geriatric Nutritional Risk Index (GNRI) is a promising tool initially proposed to predict nutrition-related complications in sub-acute care setting. So, the main aim of this study was to validate the use of GNRI in hospitalized elderly patients by testing its ability to predict patients' outcome through the comparison with Mini Nutritional Assessment (MNA). METHODS: A prospective cohort study was conducted on 131 patients aged 60 and over admitted consecutively from October 2011 to September 2012 to the acute geriatrics medical ward in Ain Shams University hospitals, Cairo, Egypt. All patients were subjected to nutritional screening using GNRI and MNA and measurement of weight, body mass index (BMI), mid arm circumference (MAC), and calf circumference (CC), serum levels of total protein, albumin and prealbumin. Patients were followed for 6 months for the occurrence of major health complications as prolonged length of stay, infectious complications and mortality. RESULTS: Mean age was 69.32 ± 8.17 years. Lower GNRI scores were statically significantly associated with worse MNA scores, lower weight, BMI, MAC, CC and albumin (P value < 0.001 for all). Only with GNRI, increasing odds ratio (OR) was seen with increasing risk of nutrition-related complication (from mild to moderate to severe). ORs (95%CI) for three month mortality were 1.63(0.0.27-10.00), 5.03(1.36-18.52), and 11.24(3.03-41.67), and OR (95%CI) for six month mortality were 1.64(0.403-6.62), 4.29 (1.45-12.66), and 5.71(1.87-17.54) respectively compared to patients with no risk and. By regression, both severe and moderate grade of GNRI were independent predictors of three and six month mortality (P value for three month: 0.002, 0.015; for six month: 0.002, 0.008 respectively) after adjustment of age, sex, and cancer rather than MNA. CONCLUSIONS: GNRI showed a higher prognostic value for describing and classification of nutritional status and nutritional-related complications in hospitalized elderly patients in addition to its simplicity.
