Hospital utilization among chronic dialysis patients

Factors driving inpatient and outpatient utilization were studied among patients who began dialysis for chronic renal failure at the New England Medical Center (NEMC) between 1992 and 1997. Clinical, laboratory, and hospital resource utilization data were obtained from patient records and electronic databases. There were 2.2 hospitalizations and 14.8 hospital days per patient year at risk (PYAR). The number of hospitalizations and hospital days per PYAR were higher in the first 3 mo of initiating dialysis (4.3 and 28.3, respectively) compared to after 3 mo (1.9 and 12.9, respectively). Factors associated with increased risk of hospital days within the first 3 mo included non-health maintenance organization insurance, ischemic heart disease, late referral to the nephrologist, and use of temporary vascular access for the first dialysis. Patients with ischemic heart disease and who received dialysis during the years 1992-1994 compared with 1996-1997 had an increased risk of hospital days after 3 mo of initiating dialysis. There were 16.6 outpatient visits per PYAR, with significant differences in utilization between the first 3 mo and after 3 mo of initiating dialysis. Thus, hospital utilization was significantly higher in the first 3 mo compared to after 3 mo, and factors associated with hospital utilization depended on duration of dialysis. In particular, delayed referral to the nephrologist and lack of permanent vascular access were independently associated with increased risk of hospital utilization in the first 3 mo of dialysis. Greater attention to timely referral to the nephrologist and timely placement of vascular access could result in reduced utilization and cost savings.     

Maternal and perinatal outcome in varying degrees of anemia.

OBJECTIVES: To analyze the maternal and perinatal outcome in varying degrees of anemia. METHODS: A total of 447 pregnant women were divided into group I (Hb>11 g%, n=123 women), group II (Hb 9-10.9 g%, n=214 women), group III (Hb 7-8.9 g%, n=79 women) group IV (Hb<7 g%, n=31 women). Their maternal and perinatal outcome, mode of delivery, duration of labor and postpartum complications were noted and analyzed using multiple logistic regression to calculate odds ratios (95% CI) for duration of labor, mode of delivery and low birth babies. Chi square or Fisher's exact test was employed for difference in proportions and Student's t-test for testing difference between means. RESULTS: Mean age (27+/-4.25 years) and number of women with parity >3 were highest in group IV. The patients with Hb<8.9 g% had a 4-6-fold higher risk of prolonged labor compared to Hb>11 g%. The odds ratios for abnormal delivery (cesarean and operative vaginal deliveries) showed a 4.8-fold higher risk (95% CI 1.82, 12.7) in patients with Hb 相似文献   

Thigh bleeding time as a valid indicator of hemostatic competency during surgical treatment of patients with advanced renal disease

We compared the usefulness of the modified Ivy bleeding time performed in the forearm (arm bleeding time) with that performed in the thigh (thigh bleeding time) as an indicator of hemostatic competence during surgical treatment in 16 patients with chronic renal failure. In 22 normal adults, the arm bleeding time (mean plus or minus standard deviation, 6.6 +/- 1.4 minutes) was significantly longer than the value in the thigh (mean plus or minus standard deviation, 4.1 +/- 1.3 minutes) (p less than 0.001), and there was no correlation between arm and thigh bleeding time. Preoperatively, the arm bleeding time in patients with renal disease was markedly prolonged (greater than 20 minutes) in 15 patients and slightly prolonged in one patient. There was no abnormal perioperative bleeding in 13 patients whose preoperative thigh bleeding time was seven minutes or less. Prolonged and excessive perioperative bleeding was observed in three patients whose thigh bleeding time was 8.0, 9.5 and 26.5 minutes. These findings suggest that thigh bleeding time is a better indicator of competence of primary hemostasis during the operation than the arm bleeding time in patients with advanced renal failure.     

Cytomorphology of some uncommon tumors of childhood and adolescence

With the advent of newer adjuvant chemotheraputic regimes resulting in dramatic improvement in survival, it is mandatory to obtain quick correct diagnosis, which is provided by fine needle aspiration cytology (FNAC). Cytology of childhood tumors was studied to find any distinguishing features, which would help in arriving at a diagnosis. Cytomorphology of 386 childhood and adolescent (0–19 years) tumors diagnosed between 1984 and 1993 were studied. Lipoma was the commonest benign tumor in 0–14 years age group. Fibroadenoma of the breast was the common benign tumor in adolescent (10–19 yrs) girls and pleomorphic adenoma in adolescent (15–19 yrs) boys. Wilms' tumor was the most frequent solid malignant tumor in preschool children and Hodgkin lymphoma, mixed cellularity in the school going age (5–19 yrs). Malignant tumors were more frequent (199). In addition, some rare malignancies like hepatoblastoma, meningioma, ganglioneuroblastoma, adrenocortical carcinoma, clear cell sarcoma kidney and malignant histiocytosis were diagnosed. The cytological features and the differential diagnoses are discussed. It is possible to diagnose these uncommon tumors if particular attention is paid to the distinguishing cytomorphological features in correlation with clinicoradiological findings and cytochemistry.     

Phytochemicals based chemopreventive and chemotherapeutic strategies and modern technologies to overcome limitations for better clinical applications

Naturally occurring phytochemicals or plant derivatives are now being explored extensively for their health's benefits and medicinal uses. The therapeutic effect of phytochemicals has been reported in several pathophysiological settings such as inflammatory disorders, metabolic disorders, liver dysfunction, neurodegenerative disorders, and nephropathies. However, the most warranted therapeutic effects of phytochemicals were mapped to their anticancerous and chemopreventive action. Moreover, combining phytochemicals with standard chemotherapy has shown promising results in cancer therapy with minimal side effects and better efficacy. Many phytochemicals, like curcumin, resveratrol, and epigallocatechin‐3‐gallate, have been extensively investigated for their chemopreventive as well as chemotherapeutic effects. However, poor bioavailability, low solubility, hydrophobicity, and obscure target specificity restrict their therapeutic applications in the clinic. There has been a continually increasing interest to formulate nanoformulations of phytochemicals by using various nanocarriers, such as liposomes, micelles, nanoemulsions, and nanoparticles, to improve their bioavailability and target specificity, thereby maximizing the therapeutic potential. In the present review, we have summarized chemopreventive as well as chemotherapeutic action of some common phytochemicals and their major limitations in clinical application. Also, we have given an overview of strategies that can improve the efficacy of phytochemicals for their chemotherapeutic value in clinical settings.     

Diagnosis and Management of Rhabdomyosarcoma in Children and Adolescents: ICMR Consensus Document

Rhabdomyosarcoma (RMS) is a highly malignant tumor which is thought to originate from the pluripotent mesenchyme. It is the most common soft-tissue sarcoma of childhood. This review article summarizes the recent and older published literature and gives an overview of management of RMS in children. RMS can arise in a wide variety of primary sites, some of which are associated with specific patterns of local invasion, regional lymph nodal spread, therapeutic response and long term outcome, hence requiring physicians to be familiar with site-specific staging and treatment details. Most common primary sites include the head and neck region, genitourinary tract, and extremities. Prognosis for children and adolescents with RMS has recently improved substantially, especially for patients with local or locally extensive disease because of the development of multi-modal therapy incorporating surgery, dose-intensive combination chemotherapy, and radiation therapy. Despite aggressive approaches the outcome for patients who present with metastatic disease remains unsatisfactory. Clinical trials are ongoing to reduce toxicity and improve outcomes of such patients; newer agents in combination are being investigated.     

Designing and validation of a Hindi-language parent self-report developmental screening tool

Aim

To design and validate Hindi-language parent self-report developmental screening questionnaires for 9-month and 18-month-old Indian children.

Design

Cross-sectional study

Setting

Tertiary-care pediatric hospital from April 2014 to March 2016

Participants

In each age group (9-month and 18-month), 45 children were enrolled for designing of questionnaires (30 for obtaining parental observations of current development and 15 for pre-testing). For validation of tool, 100 children (60 low risk and 40 high risk) were enrolled in each age group.

Methods

For designing, observations regarding current developmental milestones were obtained from parents and a list of all enumerated milestones was prepared. After detailed discussion by a team of developmental pediatricians, pediatric resident, clinical psychologist and language specialist, milestones were chosen for drafting of questionnaires. In each age group, drafts were pre-tested and required modifications were done. The final questionnaires contained 20 items each to be scored on a Likert scale (total score ranging from 20 to 60, a lower score indicating a higher risk of developmental delay). These questionnaires were validated against Developmental Assessment Scale for Indian Infants (DASII), a gold standard instrument.

Results

On ROC analysis, the 9-month and 18-month screening tool had area under curve of 0.988 and 0.953, respectively, for detecting developmental delay. Score ≤50 on the 9-months questionnaire had sensitivity of 100% and specificity of 87.2%. Score ≤49 on the 18-months questionnaire had sensitivity of 91.4% and specificity of 88.7%.

Conclusions

The new questionnaires have a promising role in developmental screening of children at the time of routine immunizations in our country.
