RESUMO

BACKGROUND: Paper food and gastrointestinal (GI) symptom journals are used to help irritable bowel syndrome (IBS) patients determine potential trigger foods. The primary aim of this study was to evaluate the feasibility, usability, and clinical utility of such journals as a data collection tool. A secondary aim was to explore a method for analyzing journal data to describe patterns of diet and symptoms. METHODS: Participants (N=17) were asked to log three sets of 3-day food and symptom journals over a 15-day period. Feasibility was evaluated by journal completion rates, symptom logging compliance, and logging fatigability. The feasibility, usability, and clinical utility of journaling were also assessed by a customized evaluation and exit interview. For each journal, regression analyses were conducted to examine relationships between key meal nutrients and subsequent symptoms. KEY RESULTS: Most participants were young (mean age 35±12) Caucasian (N=13) women (N=14). Journal completion rates were 100% for all participants with no logging fatigability. Over half perceived paper journaling of food and symptoms as feasible, usable, and clinically useful. Thirteen participants demonstrated a strong association with at least one symptom and meal nutrient. Patterns of associations differed among participants. CONCLUSIONS AND INFERENCES: Paper journaling of food and GI symptoms for 9 days over a 15-day period appeared to be a feasible and usable data collection tool for IBS patients. Over half perceived journaling as at least somewhat clinically useful. Findings from this study support the anecdote that food trigger(s) and associated symptom(s) vary for each individual.

RESUMO

Background. Poor inpatient glycaemic control has a prevalence exceeding 30% and results in increased length of stay and higher rates of hospital complications and inpatient mortality. The aim of this study was to improve inpatient glycaemic control by developing an alert system to process point-of-care blood glucose (POC-BG) results. Methods. Microsoft Excel Macros were developed for the processing of daily glucometry data downloaded from the Cobas IT database. Alerts were generated according to ward location for any value less than 4 mmol/L (hypoglycaemia) or greater than 15 mmol/L (moderate-severe hyperglycaemia). The Diabetes Team provided a weekday consult service for patients flagged on the daily reports. This system was implemented for a 60-day period. Results. There was a statistically significant 20% reduction in the percentage of hyperglycaemic patient-day weighted values >15 mmol/L compared to the preimplementation period without a significant change in the percentage of hypoglycaemic values. The time-to-next-reading after a dysglycaemic POC-BG result was reduced by 14% and the time-to-normalization of a dysglycaemic result was reduced from 10.2 hours to 8.4 hours. Conclusion. The alert system reduced the percentage of hyperglycaemic patient-day weighted glucose values and the time-to-normalization of blood glucose.

RESUMO

Understanding the consequences of miR-145 reintroduction in human breast cancer (BC) could reveal its tumor-suppressive functions and may disclose new aspects of BC biology. Therefore, we characterized the effects of miR-145 re-expression in BC cell lines by using proliferation and apoptosis assays. As a result, we found that miR-145 exhibited a pro-apoptotic effect, which is dependent on TP53 activation, and that TP53 activation can, in turn, stimulate miR-145 expression, thus establishing a death-promoting loop between miR-145 and TP53. We also found that miR-145 can downregulate estrogen receptor-alpha (ER-alpha) protein expression through direct interaction with two complementary sites within its coding sequence. In conclusion, we described a tumor suppression function of miR-145 in BC cell lines, and we linked miR-145 to TP53 and ER-alpha. Moreover, our findings support a view that miR-145 re-expression therapy could be mainly envisioned in the specific group of patients with ER-alpha-positive and/or TP53 wild-type tumors.

RESUMO

To determine whether the results of the self-reported International Index of Erectile Function (IIEF) to assess erectile function can overestimate the degree of erectile impairment. A total of 32 consecutive patients seeking treatment for erectile dysfunction (ED) at a urologist's office were evaluated by completion of the erectile function domain of the IIEF. Nocturnal penile tumescence testing using the Rigiscan (Timm Medical Technologies Inc., USA) was performed in these patients after completion of the IIEF. The median IIEF-6 score was 9 of 30 (range, 1-25; mean, 11/30). Rigiscan results were abnormal in six patients (19%), normal in 25 patients (78%), and unable to interpret in one patient (3%). IIEF-6 scores were subdivided by severity along with Rigiscan results. There was no correlation between age, IIEF score, or Rigiscan results. In conclusion, the IIEF is a useful tool and is helpful for follow-up of a patient to evaluate efficacy of treatments for ED, but should not replace objective testing to diagnose the quality of ED.

RESUMO

To evaluate and compare the cutaneous temperature of the penis in normal men, those with erectile dysfunction (ED), those with semirigid penile prostheses (SRPPs), and those with inflatable penile prostheses (IPPs), and those before and after trimix injection to create a penile erection. A total of 68 patients were evaluated. Five patient groups were identified, including men with normal erectile function, with ED, with SRPPs, with IPPs, and following intracavernosal injection of trimix solution. Cutaneous glans temperature increased significantly by more than 2.2 degrees C in the trimix-injected group compared with all other groups (P<0.001). Using cutaneous temperature measurements of the penis, patients with SRPPs had significantly lower cutaneous glans temperatures than normals (P<0.02), those in the ED group (P<0.04), and those in the IPP-deflated group (P<0.01). The mean temperature difference was 1.44+/-0.40 degrees C. Using cutaneous temperature measurements of the penis, men with SRPPs have a colder glans as compared with men with normal erectile function, ED, IPPs, and those who have received an injection of trimix. Men with normal erectile function, ED, and IPPs did not have significant cutaneous temperature differences.

RESUMO

Two new short forms of the Boston Naming Test (BNT) were developed using item response theory (IRT) with data from 206 elderly outpatients. We evaluated the diagnostic ability of 12 short forms among the full sample and in a sub-sample of 69 patients diagnosed with mild Alzheimer's disease (AD) either alone or in combination with vascular dementia (VD). The full BNT (reliability alpha = .90) identified 44% of the AD/VD patients as abnormal on naming. Our 30 item short form (alpha = .90) also identified 44% of the AD/VD patients as abnormal, with 93% agreement with the full BNT on abnormal AD/VD patient classifications. Our 15 item short form (alpha = .84) identified 48% of the AD/VD patients as abnormal, with 90% agreement with the full BNT's abnormal classifications. An adaptive 30/15 item version equaled the performance of the full 30 item test while requiring only 15 items for 75% of the patients with normal naming ability. This study illustrates the utility of IRT for developing neuropsychological assessment tools.

RESUMO

PURPOSE: This study was a comparison of the symptomatology associated with placement of the upper coil of a double-pigtail stent in the upper pole or the renal pelvis. PATIENTS AND METHODS: A prospective study with 40 patients was performed. In 20 patients, the stent was placed in the upper pole (Group A) and in another 20 patients (Group B) in the renal pelvis. A questionnaire was addressed to all patients before the removal of the stent concerning the presence and severity of flank pain (using a standardized 10-point scale), the presence and severity of urinary urgency (using a standardized 10-point scale), the presence of dysuria, and quality of life with the stent in place. RESULTS: Flank pain was present in 17 (85%) and 15 (75%) patients in Groups A and B, respectively. The average severity of flank pain was 4.3 (range 0-7) and 4.5 (range 0-10) in Group A and B, respectively (p = 0.764). Urinary urgency was present in 13 (65%) and 15 (75%), patients in Group A and B, respectively. The average severity of urgency was 3.1 (range 0-7) and 5.3 (range 0-10) in Group A and B, respectively (p = 0.037). Dysuria was present in 4 (20%) and 13 (65%), and the average quality of life score was 2.5 and 3.05 in Group A and B, respectively (p = 0.04). CONCLUSION: Positioning of the proximal end of the double-pigtail stent in the upper pole of the kidney appears to be better tolerated by patients than is the standard insertion in the renal pelvis.

RESUMO

PURPOSE: A standard electrode surgical generator connected to a Nitinol coil was used in vitro to evaluate whether the generated electromagnetic energy had any bactericidal effect on Escherichia coli. MATERIALS AND METHODS: The ATCC 259222 E. coli strain was used. We mixed 135 mL of a 1.5% non-nutritive agar with 15 mL of a 10(6) CFU/mL inoculum and transferred it to gas-sterilized plastic containers lined with aluminium foil. A 22F cylindrical shape was cut from the center of the agar, and a Nitinol coil was placed in that space and connected to a standard electrode surgical generator. Electrical energy was then applied from 5 to 25 V at 5-V increments. Temperatures were measured with two thermocouples placed in the middle and periphery of each agar. The treatment was stopped when the temperature at the middle thermometer reached 50 degrees C. The control group was not treated and was embedded in a water bath at 45 degrees C. Three 3 x 7-mm pieces were sliced from the inner to the outer part of the agar and processed, and colony counts were performed. RESULTS: We observed statistically significant deleterious effects on E. coli in all three zones when the treatment voltage was 15 and 20. When the potential was raised to 25 V, we observed a significant result only in the core zone. The treatment duration was 50 minutes for 5 and 10 V, 45 minutes for 15 V, 15 minutes for 20 V, and 10 minutes for 25 V. CONCLUSION: The bactericidal effect was mainly in the central area, decreasing linearly toward the periphery, and was related to the temperature reached during activation of the electrical generator. These results were disappointing with regard to the utility of Nitinol stents to treat bacterial prostatitis.

RESUMO

BACKGROUND: As a result of the decline in Haemophilus influenzae type b (Hib) disease caused by the widespread use of conjugate vaccines, non-type b H. influenzae will become a more important cause of H. influenzae (Hi) disease. Characterization of the clinical and epidemiologic features of non-b Hi disease is needed in the Hib vaccine era. METHODS: A prospective active surveillance study of invasive Hi disease involving pediatricians in the United Kingdom and Republic of Ireland. For the first phase of the study (October 1, 1992, to October 31, 1995) pediatricians were asked to report any child who had invasive Hi disease and who had received Hib conjugate vaccine. For the second phase of the study (November 1, 1995. To December 31, 1998) pediatricians were asked to report any child with invasive Hi disease regardless of vaccination status. RESULTS: During the study period 102 cases of invasive non-type b Hi disease and 106 cases of invasive Hib disease were reported in children who had been fully vaccinated against Hib. Children with non-type b disease were younger (16 vs. 22 months of age, P = 0.08), less likely to have meningitis and epiglottitis (P < or = 0.001) and more likely to have pneumonia and bacteremia (P < or = 0.001) than children with type b disease. For the last 2 years of the study invasive Hi disease occurring in a fully vaccinated child was more likely to be caused by a non-b strain than by a type b strain (58 vs. 38). In 1998 the incidence of non type-b Hi disease in all children <5 years of age in the UK was 1.3/100,000 as compared with an incidence of Hib disease of 0.6/100,000. The majority (88%) of non-b strains isolated in children were nontypable strains. CONCLUSIONS: Non-b Hi is a rare cause of disease in children, but in the Hib vaccine era it has become more common than type b as a cause of Hi disease in fully vaccinated children.

RESUMO

The Interdisciplinary Generalist Curriculum (IGC) Project required significant collaboration and cooperation at many levels of leadership to accommodate early clinical experiences in the curriculum. Three elements of institutional change are discussed: the context for desired early clinical experiences in medical education, structural elements required of the IGC Project schools, and leadership within the demonstration schools. Lessons learned from these interdisciplinary projects include the importance of supportive leadership from the top levels, establishing broad buy-in across sectors of the school, creating a team administrative structure that fosters participation by all groups, and central (rather than departmental) administration. The processes needed to establish collaborative leadership and full participation by the generalist departments and cooperation of diverse constituencies, such as basic science faculty, were labor-intensive and required more time to ensure successful program implementation. Uniformly, strong support at the highest levels of the organization, especially the medical schools' deans, was cited as a key element in the success of the IGC Project. An interesting unanticipated outcome of the project was the movement of the interdisciplinary course administration into a central location (dean's office) by the end of the project for all schools. This change may reflect a practical advantage for administration of interdisciplinary programs located at the level of the school or college, rather than housed within departments.

RESUMO

The University of Vermont College of Medicine received its Vermont Generalist Curriculum (VGC) subcontract as one of the second-cycle Interdisciplinary Generalist Curriculum (IGC) Project schools from 1995 to 1998. The Vermont program was jointly codirected by the chairs of family practice and pediatrics and the program director for internal medicine on a rotating basis and was overseen by a multidisciplinary steering committee that included generalists, basic scientists, specialists, and students. This committee provided guidance and support in recruitment of preceptors, continuous assessment and improvement of the courses, development of a clinical correlation manual for students in clinical offices, and cooperation around a jointly sponsored annual primary care meeting that included a joint scientific program, a research forum, and a faculty development workshop. The VGC has provided a pilot for many innovative curricular changes that have served as models for the school-wide curriculum redesign process currently under way at VERMONT: While the funding for this project ended in 1998, the changes, innovations, and collaboration born out of the project are valuable enough for the dean's office to maintain the VGC's funding and its steering committee for the future.

RESUMO

Hepatitis A and B viruses are threats to deployed military forces. The objective of this study was to determine the feasibility of concurrent vaccination against hepatitis A and B viruses. One hundred five healthy persons, 20 to 49 years of age and without serologic markers to hepatitis A or B viruses, were randomized to receive an inactivated hepatitis A vaccine (HEP A; 25 units in 0.5 mL), recombinant hepatitis B vaccine (HEP B; 10 micrograms in 1.0 mL), or both (HEP A & B) concurrently in separate arms. Vaccines were administered intramuscularly at 0, 1, and 6 months. Sera obtained at 1, 2, 6, 7, and 12 months after the first dose were tested for quantitative antibody to hepatitis A virus (anti-HAV) and antibody to hepatitis B surface antigen. Local reactions (e.g., pain) were reported by less than half of the volunteers and were similar at the site of HEP A, whether given alone or concurrently. However, more persons complained of pain (usually mild) at the HEP B site when HEP B was given concurrently with HEP A compared with HEP B alone (43% vs. 15%, 34% vs. 9%, and 42% vs. 15% for doses 1, 2, and 3, respectively; p < 0.05 for each dose). Among persons immunized with HEP A alone or HEP A & B, the proportion with > or = 10 mIU/mL anti-HAV was 83% in both groups 1 month after dose 1 and 100% at months 2, 7, and 12. The geometric mean concentrations of anti-HAV increased from 21 mIU/mL at month 1 to 2,649 and 2,312 mIU/mL in the HEP A and HEP A & B groups, respectively, at month 7. The response to HEP B was similar whether administered alone or concurrently. Antibody responses were similar in those receiving HEP A or HEP B concurrently or alone, but more subjects reported pain (usually mild) at the HEP B site after concurrent vaccination than after HEP B alone. Further work should be conducted to approve HEP A for patients younger than 2 years of age and to develop combined HEP A and HEP B vaccines in the United States.

RESUMO

PURPOSE: The efficiency and efficacy of the available intracorporeal ultrasonic lithotripters were compared in a stone model experiment. MATERIALS AND METHODS: Plaster of Paris (POP) stone phantoms having ratios of 1:1, 1.5:1, and 2:1 with water were fabricated into cubes of various hardnesses weighing an average of 24.6 g. The stones were immersed in water in a plastic container, and continuous irrigation through a rigid nephroscope was used. Ultrasonic lithotripters from ACMI, Olympus, Storz, and Wolf manufacturers were evaluated for efficacy in breaking up the three POP concentrations. Time to complete stone fragmentation, occurrence of probe or tubing occlusion, and probe overheating were evaluated. RESULTS: Efficiency of fragmentation and time to fragmentation of the Storz lithotripter were significantly different from those of the Wolf (p = 0.01 and p = 0.02, respectively) and ACMI (p = 0.001 and p = 0.02, respectively) lithotripters. Comparison of the efficiency of fragmentation and time to fragmentation of the ACMI and Wolf lithotripters showed significant differences (p = 0.005 and p = 0.03, respectively) in favor of the Wolf device. The Olympus lithotriptor resulted in incomplete fragmentation of phantoms of all POP concentrations. CONCLUSION: The Storz ultrasonic lithotriptor was found to have the lowest fragmentation time and highest efficiency in the fragmentation of phantom stones.

RESUMO

Haemophilus influenzae type b (Hib) conjugate vaccines have proved extremely efficacious in healthy children. True Hib vaccine failures are rare. Hib conjugate vaccines were introduced for routine immunization in the United Kingdom and the Republic of Ireland in 1992. Coincident with this, active prospective and national surveillance via pediatricians, microbiologists, and public health physicians was commenced to assess the clinical and immunological factors associated with vaccine failure. During the 6 years of the study, 115 children with true vaccine failure were reported. Of the children who were vaccinated before 12 months of age, a clinical risk factor was detected in 20%, an immunological deficiency was detected in 30%, and one or both were detected in 44%. Children who were vaccinated after 12 months of age were more likely to have one or both factors (67%). Thirty percent (33 of 105) of children with true vaccine failure had a low Hib antibody response (concentration, <1.0 microg/mL) after disease, but the majority then responded to a further dose of Hib vaccine. Children who develop Hib disease despite vaccination deserve further clinical and immunological evaluation.

RESUMO

OBJECTIVES: The purpose of this study was to evaluate whether repair of the ureteropelvic junction (UPJ) obstruction reduces the incidence of stones in stone-forming patients with concurrent UPJ obstruction. METHODS: We performed a retrospective study evaluating 90 patients with UPJ obstruction who underwent endopyelotomy and simultaneous stone extraction (group A) and 80 patients without UPJ obstruction who underwent only stone extraction (group B). Group A consisted of 52 men and 38 women with an average age of 54.4 years (range 15 to 82), and group B of 46 men and 34 women with an average age of 53.5 years (range 8 to 94). Metabolic evaluation was available in 47 patients of group A and 42 patients of group B. RESULTS: We achieved a stone-free state in all patients of both groups. Stone recurrence was observed in 7 patients (8%) in group A and in 32 patients (40%) in group B. Nine of 47 patients (19%) in group A showed metabolic abnormalities. In group B we found 30 of 42 patients (71.4%) with metabolic abnormalities. CONCLUSIONS: Our results suggest that correction of the anatomic obstruction facilitates the drainage of the previously entrapped urine, and thus decreases the incidence of recurrent urinary stone formation.

RESUMO

Since the mid-1980s, a 'mysterious' disease has been afflicting the moose (Alces alces L.) population of south-western Sweden. Molybdenosis combined with secondary copper deficiency syndrome has been suggested as the cause of the clinical signs and of necropsy findings, supported by trace element analysis. Copper deficiency has long been associated with disturbed carbohydrate metabolism and also with oxidative stress. When testing the oxidative stress hypothesis, we found increased concentrations of the glycoxidation products pentosidine and carboxymethyl-lysine (CML), both in plasma proteins and in renal tissue, when compared with control values. The concentration of glycated lysine (furosine), a marker of hyperglycaemia, was also increased. These data, together with elevated insulin levels in affected moose, strongly suggest that they are suffering from an environmentally-induced, non-insulin-dependent type 2 diabetes.

RESUMO

BACKGROUND: Vigilance, the close protective involvement of family members with hospitalized relatives, is a relatively recent phenomenon in the hospital setting. Before the 1960s, hospital visiting policies restricted the presence of family members at the bedside. Policies changed during the 1960s and 1970s when health care professionals recognized that parents' staying with their hospitalized children was beneficial for both the parents and the children. Vigilance later became a phenomenon that included family members staying with adult patients. METHODS: Two ethnographic studies were conducted to examine the meanings, patterns, and day-to-day experience of vigilance. Sixteen family members, described by the nursing staff as staying with the patient, participated in informal semistructured interviews. Participant observation was also used in data collection. RESULTS: Data analysis yielded 5 categories of meaning that describe the experience of vigilance: commitment to care, emotional upheaval, dynamic nexus, transition, and resilience. CONCLUSIONS: Managed care, shortened hospital stays, and cost containment make early involvement of the family in the patient's care imperative. An understanding of the family's needs and experiences is prerequisite to that involvement. The categories of meaning discovered in this research can help health care providers understand family members' experience of vigilance. The implications for the family physician include sensitization and awareness of family members' experiences and the developing of specific actions and interactions fostering a commitment to family-centered care that extends to the hospital setting.

RESUMO

The present experiments examined the impact of manipulating the NO system on production of isolation-induced ultrasonic vocalizations (USVs) in 10- and 11-day-old rat pups. Pups were tested under both high- and low-baseline USV emission; the latter was accomplished by pretest administration of cocaine, a drug known to suppress USVs. Treatment with 10, 50, or 100 mg/kg (but not 1 mg/kg) of the nitric oxide synthase (NOS) inhibitor L-nitro-arginine methyl ester (L-NAME) significantly attenuated USV production, as did injection of 10 mg/kg cocaine; combined treatment with both drugs did not result in greater suppression, perhaps due to a floor effect. Although cocaine increased locomotor activity, treatment with L- or D-NAME alone did not alter activity levels. Exposure to L-NAME induced some hypothermia, although these alterations in body temperature were not systematically related to the drug-induced suppression of USVs. Alterations in USV production by L-NAME were not evident after pretreatment with the less active isomer D-NAME, evidence supporting the importance of NO synthesis inhibition per se in the marked L-NAME-induced suppression of USVs in isolated infant rats.

RESUMO

The relationships between long-term intensive control of glycemia and indicators of skin collagen glycation (furosine), glycoxidation (pentosidine and N(epsilon)-[carboxymethyl]-lysine [CML]), and crosslinking (acid and pepsin solubility) were examined in 216 patients with type 1 diabetes from the primary prevention and secondary intervention cohorts of the Diabetes Control and Complications Trial. By comparison with conventional treatment, 5 years of intensive treatment was associated with 30-32% lower furosine, 9% lower pentosidine, 9-13% lower CML, 24% higher acid-soluble collagen, and 50% higher pepsin-soluble collagen. All of these differences were statistically significant in the subjects of the primary prevention cohort (P < 0.006-0.001) and also of the secondary intervention cohort (P < 0.015-0.001) with the exception of CML and acid-soluble collagen. Age- and duration-adjusted collagen variables were significantly associated with the HbA1c value nearest the biopsy and with cumulative prior HbA1c values. Multiple logistic regression analyses with six nonredundant collagen parameters as independent variables and various expressions of retinopathy, nephropathy, and neuropathy outcomes as dependent variables showed that the complications were significantly associated with the full set of collagen variables. Surprisingly, the percentage of total variance (R2) in complications explained by the collagen variables ranged from 19 to 36% with the intensive treatment and from 14 to 51% with conventional treatment. These associations generally remained significant even after adjustment for HbA1c, and, most unexpectedly, in conventionally treated subjects, glycated collagen was the parameter most consistently associated with diabetic complications. Continued monitoring of these subjects may determine whether glycation products in the skin, and especially the early Amadori product (furosine), have the potential to be predictors of the future risk of developing complications, and perhaps be even better predictors than glycated hemoglobin (HbA1c).

RESUMO

Spouse abuse is a major social issue in our country. Based on national samples, between 10 and 20% of couples report some type of violence during the course of their marriage. In the United States, 1.8 million women are physically abused by their spouses each year. Within the military, it is estimated that the incidence of spouse abuse is even greater than in the civilian sector. Estimates suggest that one-third of military spouses experience abuse during their marriage. Although 87% of women prefer discussing their victimization with their physician, physicians, as a group, have been least effective in helping them. Recently, several barriers to physician recognition and intervention in domestic violence have been identified, and recommendations for specific training on abuse have been published. This paper provides military physicians an in-depth review of the guidelines to identification, diagnosis, and management of spouse abuse, with a special emphasis on their implementation within the uniformed services.
