RESUMEN
Despite the advances in cancer outcomes, significant health disparities persist. Several new agents have been recently approved for treatment of lymphomas, leading to improved outcomes. Extending the benefits of these new agents starts by adequate enrollment of all affected patient populations. This study aimed to evaluate the extent to which randomized controlled trials (RCTs) match the demographic and geographic diversity of the population affected by lymphoma. Two Food and Drug Administration databases, clinicaltrials.gov, and relevant primary manuscripts were reviewed for drug approval data and demographic representation in RCTs for classical Hodgkin lymphoma (cHL) and non-Hodgkin lymphoma. Maps showing the distribution and frequency of trial participation relative to disease burden, insurance status, and racial representation were created. Black, Hispanic, and female patients were significantly underrepresented in the RCTs for lymphoma compared with that for the disease burden (3.6% [95% confidence interval (CI), 2.8-5.4] vs 14.6% [95% CI, 13.8-15.3]; 6.7% [95% CI, 5.5-7.9] vs 16.3% [95% CI, 15.5-17.1]; and 39.1% [95% CI, 37.3-40.9] vs 42.7% [95% CI, 42.3-43.1], respectively). White and male patients were overrepresented. More counties with higher mortality rates and racial minority representation had low access to the trials, particularly for cHL in the southern region of the United States. There are significant racial misrepresentations in pivotal RCTs in the United States, and geographic distribution of these trials may not provide easy access to all patients in need. Disparities in enrollment should be corrected to make results applicable to all populations.

Wedelia chinensis is a folk medicine used in many Asian countries to treat various ailments. Earlier investigations reported that the petroleum ether extract of the plant has potential biological activity, but the compounds responsible for activity are not yet completely known. Therefore, the current work was designed to isolate and characterize the compounds from the petroleum ether extract and to study their bioactivities. Four compounds including two diterepenes (-) kaur-16α-hydroxy-19-oic acid (1) and (-) kaur-16-en-19-oic acid (2), and two steroids ß-sitosterol (3), and cholesta-5,23-dien-3-ol (4) were isolated and characterized. Among the compounds, the diterpenes were found to have more biological activities than the steroidal compounds. Compound 1 showed the highest cytotoxicity with LC50 of 12.42 ± 0.87 µg/mL. Likewise, it possesses good antioxidant activity in terms of reducing power. On the contrary, compound 2 exerted the highest antiacetylcholinesterase and antibutyrylcholinesterase activity. Both the diterpenes showed almost similar antibacterial and antifungal activity. The identification of diterpenoid and steroid compounds with multifunctional activities suggests that W. chinensis may serve as an important source of bioactive compounds which should be further investigated in animal model for therapeutic potential in the treatment of different chronic diseases.

Neurotoxicity is a serious health problem of patients chronically exposed to arsenic. There is no specific treatment of this problem. Oxidative stress has been implicated in the pathological process of neurotoxicity. Polyphenolics have proven antioxidant activity, thereby offering protection against oxidative stress. In this study, we have isolated the polyphenolics from Acacia nilotica and investigated its effect against arsenic-induced neurotoxicity and oxidative stress in mice. Acacia nilotica polyphenolics prepared from column chromatography of the crude methanol extract using diaion resin contained a phenolic content of 452.185 ± 7.879 mg gallic acid equivalent/gm of sample and flavonoid content of 200.075 ± 0.755 mg catechin equivalent/gm of sample. The polyphenolics exhibited potent antioxidant activity with respect to free radical scavenging ability, total antioxidant activity and inhibition of lipid peroxidation. Administration of arsenic in mice showed a reduction of acetylcholinesterase activity in the brain which was counteracted by Acacia nilotica polyphenolics. Similarly, elevation of lipid peroxidation and depletion of glutathione in the brain of mice was effectively restored to normal level by Acacia nilotica polyphenolics. Gallic acid methyl ester, catechin and catechin-7-gallate were identified in the polyphenolics as the major active compounds. These results suggest that Acacia nilotica polyphenolics due to its strong antioxidant potential might be effective in the management of arsenic induced neurotoxicity.

Bangladesh is one of the top-ten most heavily burdened countries for viral hepatitis, with hepatitis B (HBV) infections responsible for the majority of cases. Recombinant and occult HBV infections (OBI) have been reported previously in the region. We investigated an adult fever cohort (n=201) recruited in Dhaka, to determine the prevalence of HBV and OBI. A target-enrichment deep sequencing pipeline was applied to samples with HBV DNA >3.0 log10 IU ml-1. HBV infection was present in 16/201 (8â%), among whom 3/16 (19â%) were defined as OBI (HBsAg-negative but detectable HBV DNA). Whole genome deep sequences (WGS) were obtained for four cases, identifying genotypes A, C and D. One OBI case had sufficient DNA for sequencing, revealing multiple polymorphisms in the surface gene that may contribute to the occult phenotype. We identified mutations associated with nucleos(t)ide analogue resistance in 3/4 samples sequenced, although the clinical significance in this cohort is unknown. The high prevalence of HBV in this setting illustrates the importance of opportunistic clinical screening and DNA testing of transfusion products to minimise OBI transmission. WGS can inform understanding of diverse disease phenotypes, supporting progress towards international targets for HBV elimination.

OBJECTIVES: We assessed the 30-day readmission rate of a privately insured population diagnosed with colorectal cancer (CRC) who had primary tumor resection in rural and urban communities. METHODS: Claims data of people aged <65 with a diagnosis of CRC between 2012 and 2016 and enrolled in a private health plan administered by BlueCross BlueShield of Nebraska were analyzed. Readmission was defined as the number of discharged patients who were readmitted within 30 days, divided by all discharged patients. Multivariate logistic regression was used to estimate the factors associated with readmission. RESULTS: The urban population had a higher readmission rate (11%) than the rural population (8%). Although the adjusted odds ratio showed that there is no difference in readmission between rural and urban residents, patients with a Charlson Comorbidity Index (CCI) of >1 were more likely than those without CCI to be readmitted (OR 3.59, 1.41-9.11). Patients with open vs. laparoscopic surgery (OR 2.80, 1.39-5.63) and those with an obstructed or perforated colon vs. none (OR 7.17, 3.75-13.72) were more likely to be readmitted. CONCLUSIONS: Readmission after CRC surgery occurs frequently. Interventions that target the identified risk factors should reduce readmission rates in this privately insured population.

BACKGROUND: With fewer than 7% of patients with small cell lung cancer (SCLC) surviving 5 years after diagnosis, the receipt of recommended treatment is of utmost importance for patient survival. Nevertheless, treatment refusal by patients with SCLC has not been studied well. Our study examined factors associated with treatment refusal and the effect of refusal on patient survival. METHODS: From the National Cancer Database, we analyzed data of 107,988 patients with SCLC diagnosed between 2003 and 2012. Treatment refusals were analyzed separately for chemoradiotherapy among patients with limited stage disease (LS-SCLC) and chemotherapy among those with extensive stage disease (ES-SCLC). We used logistic regression to investigate factors associated with treatment refusal. We estimated survival probability using the Kaplan-Meier method and compared survival of those who received and refused treatment using Cox proportional hazards regression analysis. RESULTS: The refusal rates of chemoradiotherapy among patients with LS-SCLC and chemotherapy among those with ES-SCLC were 1.34% and 4.70%, respectively. From 2003 to 2012, trends show an increase of refusals, especially among the patients with ES-SCLC who were recommended chemotherapy. Multivariable analyses showed that in both SCLC groups, older age at diagnosis (>70 years), female gender, uninsured status, and presence of comorbidities were associated with treatment refusals. Patients with LS-SCLC who refused chemoradiotherapy had a higher risk of mortality than those who received treatment (HR, 4.96; 95% CI, 4.45-5.53); the median survival of those who refused treatment was 3 months vs 18 months for those who received it (P < .001). Similarly, patients with ES-SCLC who refused chemotherapy had a higher risk of mortality than those who received treatment (HR, 3.69; 95% CI, 3.48-3.92); the median survival was 1 month vs 7 months, respectively (P < .001). CONCLUSIONS: Treatment refusal among patients with SCLC was associated with worse survival. Strategies to increase patient acceptance of the recommended treatment need to be studied further.

Disease fatality associated with Ebola, SARS-CoV and dengue infections in humans is attributed to a cytokine storm that is triggered by excessive pro-inflammatory responses. Interleukin (IL)-6 acts as a mediator between pro- and anti-inflammatory reactivity by initiating trans- and classical-signaling, respectively. Hence, IL-6 is assumed to provide a target for a broad range of antiviral agents. Available immunosuppressive antivirals are directed to control an often exaggerated pro-inflammatory response that gives rise to complex clinical conditions such as lymphocytopenia. It is known that IL-6, via its soluble receptor (sIL-6R), initiates a pro-inflammatory response while an anti-inflammatory response is triggered by the membrane-bound IL-6 receptor (IL-6R). Future antivirals should thus aim to target the mechanism that regulates switching between IL-6 trans- and classical-signaling. In this review, we propose that the tumour necrosis factor-α converting enzyme ADAM-17 could be the master molecule involved in regulating IL-6 class switching and through this in controlling pro- and anti-inflammatory responses to viral antigenic stimuli. Therefore, ADAM-17 should be considered as a potential target molecule for novel antiviral drug discovery that would regulate host reactivity to infection and thereby limit or prevent fatal outcomes.

BACKGROUND: In the U.S., lung cancer accounts for 14% of cancer diagnoses and 28% of cancer deaths annually. Since no cure exists for advanced lung cancer, the main treatment goal is to prolong survival. Chemotherapy regimens produce side effects with different profiles. Coupling this with individual patient's preferred side effects could result in patient-centered choices leading to better treatment outcomes. There are apparently no previous studies of or tools for assessing and utilizing patient chemotherapy preferences in clinical settings. The long-term goal of the study was to facilitate patients' treatment choices for advanced-stage lung cancer. A primary aim was to determine how preferences for chemotherapy side effects relate to chemotherapy choices. METHODS: An observational, longitudinal, open cohort study of patients with advanced-stage non-small cell lung cancer (NSCLC) was conducted. Data sources included patient medical records and from one to three interviews per subject. Data were analyzed using Chi-square, Fisher's Exact and McNamara's test, and logistic regression. RESULTS: Patients identified the top three chemotherapy side effects that they would most like to avoid: shortness of breath, bleeding, and fatigue. These side effects were similar between first and last interviews, although the rank order changed after patients experienced chemotherapy. CONCLUSIONS: Patients ranked drug side effects that they would most like to avoid. Patient-centered clinical care and patient-centered outcomes research are feasible and may be enhanced by stakeholder commitment. The study results are limited to patients with advanced NSCLC. Most of the subjects were White, since patients were drawn from the U.S. Midwest, a predominantly White population.

BACKGROUND: Rural residents are less likely to receive screening for colorectal cancer (CRC) than urban residents. However, the mechanisms underlying this disparity, especially among people aged 50-64 years old with private health insurance, are not well understood. We examined the impact of travel time on stage at CRC diagnosis. METHODS: This retrospective cohort study used data from the Blue Cross and Blue Shield of Nebraska. Members of this private insurance company aged 50-64 years, diagnosed with CRC during the period 2012-2016, and continuously enrolled in the insurance plan for at least 6 months prior to CRC diagnosis, were selected for this study. Using Google Maps, we estimated patients' travel time from their home ZIP code to the ZIP code of their colonoscopy provider. Using logistic regression, we analyzed the association between stage at CRC diagnosis, travel time, use of preventive services (i.e., check-ups or counseling to prevent or detect illness at an early stage) and patient characteristics. RESULTS: A total of 307 subjects met the inclusion criteria. People who had not used preventive services 6 months prior to CRC diagnosis had 2.80 (95% CI, 1.00-7.90) times the odds of metastatic CRC compared to those who had used these services. No statistically significant association was found between travel time and metastatic CRC diagnosis (P = 0.99; 95% CI, 0.98-1.01). CONCLUSIONS: The fact that 13% of the study population presented with metastatic CRC suggests some noncompliance with preventive services such as screening guidelines. To increase screening uptake and reduce metastatic cases, employers should offer incentives for their employees to make use of preventive services such as CRC screening.

The objective of this study was to monitor the changes in growth, dry matter intake, and blood profiles (nutrition and reproductive hormones) of dairy heifers in response to green grass-based diets. Twelve crossbred heifers were equally divided into group 1: rice straw and concentrate; group 2: rice straw, green grass, and concentrate; group 3: green grass and concentrate; group 4: green grass, soybean hay, and concentrate. Dry matter intake in group 4 was found 6% higher (P < 0.05) than group 1. Negative body weight gain was found in group 1 and group 2 showed 14% higher body weight gain per 30 days compared to groups 3 and 4 (P < 0.05). Heifers in group 4 had significantly (P < 0.05) higher heart girth gain, serum albumin, urea, and blood urea nitrogen than the heifers in other groups. Endocrine parameters were found similar among groups. Overall, supply of green grass especially a mix of leguminous and non-leguminous was found advantageous in heifer feeding.

Cancer health disparities may exist based on the facility type. We aimed to determine the association between the academic status of centers and outcomes of patients with acute myeloid leukemia (AML). Using the National Cancer Data Base, we compared 1-month mortality and long-term overall survival (OS) of 60 738 patients with AML, who received first course treatment between 2003 and 2011 at academic or nonacademic centers (community cancer program, comprehensive community cancer program, and others). Multivariate analysis was done using logistic regression for one-month mortality and Cox regression with backward elimination approach for OS. Patients treated at academic centers differed from those at nonacademic centers in that they were younger with a median age of 62 versus 70 years (P < .0001), more often an ethnic minority (P < .0001), had lower education level (P = .005), lower co-morbidity score (P < .0001), a different income (P < .0001), and insurance profile (P < .0001), and more often received chemotherapy (P < .0001) and transplant (P < .0001). Receipt of care at nonacademic centers was associated with worse 1-month mortality (29% vs. 16%, P < .0001) and 5-year OS (15% vs. 25%; P < .0001). After adjusting for prognostic covariates, the 1-month mortality (odds ratio, 1.52; 95% confidence interval, CI 1.46-1.59; P < .0001) and OS were significantly worse in nonacademic centers, compared to academic centers. Our large database study suggests that the receipt of initial therapy at academic centers is associated with lower 1-month mortality and higher long-term OS. Investigation of the underlying reasons may allow reducing this disparity.

Overweight and obese individuals have an increased risk of developing the metabolic syndrome because of subsequent chronic inflammation and oxidative stress, which the antioxidant nutrient lycopene can reduce. However, studies indicate that different BMI statuses can alter the positive effects of lycopene. Therefore, the purpose of this study was to examine how BMI influences the association between serum lycopene and the metabolic syndrome. The tertile rank method was used to divide 13 196 participants, aged 20 years and older, into three groups according to serum concentrations of lycopene. The associations between serum lycopene and the metabolic syndrome were analysed separately for normal-weight, overweight and obese participants. Overall, the prevalence of the metabolic syndrome was significantly higher in the first tertile group (OR 38·6%; 95% CI 36·9, 40·3) compared with the second tertile group (OR 29·3%; 95% CI 27·5, 31·1) and the third tertile group (OR 26·6%; 95% CI 24·9, 28·3). However, the associations between lycopene and the metabolic syndrome were only significant for normal-weight and overweight participants (P0·05), even after adjusting for possible confounding variables. In conclusion, BMI appears to strongly influence the association between serum lycopene and the metabolic syndrome.

Although lung cancer is the leading cause of cancer death in the USA, there have been few studies on patient-centered advanced lung cancer treatment practices. As part of a larger research study on how to use a patient-inclusive approach in late-stage lung cancer treatment, this present study describes patient, caregiver, and provider perspectives on the role of the health care system in helping patients cope with an advanced stage lung cancer diagnosis. Four focus group sessions were conducted with six to eleven participants per group for a total of 36 participants. Two focus groups were held with patients and family members/caregivers and two with physicians and nurses. A major theme that emerged concerned coping with an advanced lung cancer diagnosis, which is the subject of this paper. The patients, caregivers, and providers spoke passionately about interactions with the health care system and volunteered examples of supportive and non-supportive relationships between patients and clinicians. They advocated for better patient-provider communication practices as well as the expanded use of patient navigation and new patient orientation programs. This study contributes additional knowledge by including the perspectives of caregivers and providers who live and work closely with patients with advanced lung cancer. The findings can inform the development of comprehensive patient-centered care plans for patients living with an advanced lung cancer diagnosis.

Lutein and its isomer zeaxanthin have gained considerable interest as possible nutritional ingredient in the prevention of age-related macular degeneration (AMD) in humans. Egg yolk is a rich source of these carotenoids. As an oxidative sensitive component, antioxidants such as α-tocopherol (T) might contribute to an improved accumulation in egg yolk. To test this, chickens were fed lutein esters (LE) with and without α-tocopherol as an antioxidant. After depletion on a wheat-soya bean-based lutein-poor diet for 21 days, laying hens (n = 42) were equally divided into three groups and fed the following diets for 21 days: control (basal diet), a LE group (40 mg LE/kg feed) and LE + T group (40 mg LE plus 100 mg T/kg feed). Eggs and blood were collected periodically. Carotenoids and α-tocopherol in yolk and blood plasma were determined by HPLC. Egg yolk was also analysed for total carotenoids using a one-step spectrophotometric method (iCheck((™)) ). Lutein, zeaxanthin, α-tocopherol and total carotenoids in egg yolk were highest after 14 days of feeding and decreased slightly afterwards. At the end of the trial, eggs of LE + T group contained higher amount of lutein (13.72), zeaxanthin (0.65), α-tocopherol (297.40) and total carotenoids (21.6) compared to the LE group (10.96, 0.55, 205.20 and 18.0 mg/kg, respectively, p < 0.05). Blood plasma values of LE + T group contain higher lutein (1.3), zeaxanthin (0.06) and tocopherol (20.1) compared to LE group (1.02, 0.04 and 14.90 mg/l, respectively, p < 0.05). In conclusion, dietary α-tocopherol enhances bioavailability of lutein reflecting higher content in egg yolk and blood plasma. Improved bioavailability might be due to increased absorption of lutein in the presence of tocopherol and/or a greater stability of lutein/zeaxanthin due to the presence of α-tocopherol as an antioxidant.

The aim of epilepsy surgery is not only to control seizures but also to curtail future adverse neurological sequelae and improve quality of life. Epilepsy surgery is a viable treatment option for selected cases of medically refractory epilepsy. A study was carried out with a series of 34 cases who underwent epilepsy surgery at Sree Chitra Tirunal Institute for Medical Science & Technology, Kerala, India during July, 2010 to December, 2010. Clinical features, operative procedures and early response to treatment were cha'racterized. Among 34 cases, main clinical manifestation was recurrent seizures. All cases were evaluated by Video Electro Encephalogram (EEG) & Magnetic Resonance Imaging (MRI) of brain with epilepsy protocol. Nearly 58% cases were diagnosed as mesial temporal sclerosis who were treated by anterior temporal lobectomy (ATL) with amygdalohippocampectomy (AH). Excision of epileptogenic foci was confirmed by preoperative Electro Cardiogram. Early response to surgery was good. However, a prolonged longitudinal follow up is essential for accurate assessment of seizure outcome.

Despite recommendations from the CDC, only 36 % of jails offer routine HIV screening to inmates. Our purpose was to explore the feasibility of rapid HIV testing at release from an urban jail, and to identify potential barriers to this process. This project was incorporated into an established partnership between the jail, local academic medical center, and local public health department. We offered rapid HIV testing at the time of release to 507 jail inmates over a 7 week period of 2013. Three hundred and two (60 %) inmates elected testing. All participating inmates received individual test counseling, HIV prevention education, and linkage to care in the community prior to release. All tested inmates received results before release; one inmate screened positive for HIV and was linked to care. Previous HIV testing was the most frequently cited reason given (60 %) among the 205 inmates who declined at the time of the study. Utilizing the partnership between the jail, public health, and an academic medical center, we found that rapid HIV testing at exit was feasible and acceptable in this urban jail setting and could provide immediate linkage to care for those in need.

BACKGROUND: Acute flaccid paralysis surveillance (AFP) is an essential strategy of the WHO's Polio Eradication Initiative. This is the first study conducted to estimate the incidence, etiology, distribution, and surveillance performance of AFP in Iraq. METHODS: Surveillance data about the AFP cases under the age of 15 years reported from Iraq during January 1997 to December 2011 were depended in the current study. RESULTS: A total of 4974 cases of AFP were reported from Iraq during the study period, with an annual incidence of 2.5/100,000 population. Guillain-Barré syndrome represented more than half of the reported cases (N = 2611, 52.5%), followed by traumatic neuritis (N = 715, 14.4%), and other CNS infections (N = 292, 5.9%). Poliomyelitis accounted for 166 (3.3%) of cases, the last reported case being in January 2000. Surveillance performance showed that all, but two, indicators were below the required WHO recommended levels. CONCLUSIONS: AFP surveillance remains the gold standard method for poliomyelitis detection. It witnessed dramatic changes over the last two decades. This has raised people's and clinicians' awareness to the importance of promptness in notifying suspected cases and timely transportation of stool specimens to the National Poliovirus Laboratory in Baghdad, or alternatively having more than one laboratory for poliovirus detection in the country, all of which are very useful measures to increase the surveillance performance in the country.

Participatory and patient-centered approaches to cancer research have been highlighted as the most appropriate means of engaging patients in the conduct of clinical research. However, there is a paucity of patient-centered outcomes research (PCOR) on lung cancer. Previous studies seeking to define lung cancer treatment success have generally not included patients' and caregivers' perceptions and views in treatment decision-making. Additionally, little is known about effective strategies for the engagement of lung cancer patients in PCOR. We sought to gain insights into the perceptions of patients, caregivers, and providers on lung cancer treatment success, as well as on strategies for patient engagement in lung cancer PCOR. Four focus groups were conducted with provider, patient, and caregiver participants from four cancer centers in Nebraska and South Dakota. A total of 36 providers, patients, and caregivers participated in this study. Patients and caregivers confirmed that survival alone should not be the measure of lung cancer treatment success and that definitions of treatment success should emphasize factors such as effective clinical guidance throughout treatment, symptom management, functionality, and quality of life. Clinician participants noted that the definition of treatment success evolved over time and appeared to be linked to patients' experiences with chemotherapy. Participants identified barriers to and facilitators of research participation and suggested strategies for the recruitment and retention of research participants. Our study indicates that patients can successfully play active and engaged roles in clinical research, ranging from participant to partner. Judging from the enthusiasm of our focus group attendees, patients and caregivers want to participate and be engaged in clinical research.

Despite continued discussion regarding the treatment of displaced femoral neck fractures, controversies continue regarding their optimal treatment, including the choice of implant and fixation method. Hemiarthroplasty is one of the option which eliminate concerns about fixation failure, nonunion, and avascular necrosis and has become the choice of surgery among the aged >60. This prospective interventional study was carried out on 28 cases at the Department of Orthopaedic Surgery, Bangabandhu Sheikh Mujib Medical University (BSMMU), from July 2009 to April 2012 to evaluate cementless, bipolar prosthesis among the active elderly patients. All subjects were evaluated with regard to postoperative clinical, functional and activity outcome (Modified Harris Hip Scoring and Hip Outcome Scoring), intra and post operative complications. One case was dropped from follow up and 22(81.48%) patients were considered to have satisfactory outcome after statistical analysis by chi-square test on at least 12 months follow up records. Although prosthetic stem valgus and periprosthetic fracture developed in 02 cases and 01 patient had sunken prosthesis, uncemented bipolar hemiarthroplasty can give significantly good functional outcomes with minimal complications for displaced intracapsular femoral neck fracture in active elderly patients.

Introduction: During the COVID-19 pandemic, Indonesia faced shortages of medical supplies and healthcare workers. With a limited supply of healthcare workers, we examined the possibility of bringing final-year nursing students into COVID-19 patient care. Methods: We conducted a cross-sectional survey among final-year nursing students to assess their willingness and readiness to work with patients with COVID-19 in Indonesia. We recruited 1,028 final-year nursing students in East Java, Indonesia, during October 7-20, 2021. Data were collected using an online questionnaire designed for this study using Google Forms. Response data were extracted from Google Forms to MS Excel 2016 for analysis. We performed univariate analysis for descriptive statistics, followed by multivariate analysis using binary logistic regression to analyze the effect of independent variables on study outcomes. Results: The characteristics of the study participants showed that most respondents were female (97.1%) and of Javanese ethnicity (75.3%). More than 90% of participants reported no chronic diseases (96.2%) and were vaccinated (81.4%). Most participants were willing to work (84.3%) and ready to work (94.4%) with patients with COVID-19. Adjusted analysis showed that sex, type of institution, ethnicity, household condition, and history of chronic diseases were independent determinants of willingness to work with patients with COVID-19. Male and private university students were significantly more willing to work with patients with COVID-19. Conclusions: Nursing students were willing to work with patients with COVID-19 during the pandemic; however, a longitudinal study is recommended for trend analysis.
