From the Taiwan Cancer Registry Database (TCRD), we enrolled patients who had received a diagnosis of p16-negative OPSCC between January 1, 2008, and December 31, 2018. The follow-up duration was from the index date to December 31, 2019. Biomarkers commonly used in clinical practice include p16 expression (determined through immunohistochemistry) and HPV 16 viral load (detected through real-time polymerase chain reaction) [

The cumulative mortality rate was estimated using the Kaplan–Meier method. Differences between the pre-CCRT PET–CT and non-pre-CCRT PET–CT groups were determined using the log-rank test. After adjustment for confounders, the Cox proportional regression model was used to model the time from the index date to all-cause mortality among the cases and controls. HRs were calculated in multivariate analysis with adjustment for sex, age, AJCC clinical stage, differentiation, CCI score, diagnosis year, and hospital volume. All analyses were performed using SAS (version 9.4; SAS, Cary, NC, USA). Two-tailed

According to the NCCN guidelines [Most previous studies have investigated both p16-positive and p16-negative OPSCC [Many studies have reported that PET–CT can be used for determining the response to treatments, including CCRT, or for the detection of recurrence in head and neck cancers [Compared with the control group, more patients in the case group had advanced AJCC stages, advanced cN stages, and poor differentiation, which were identified as poor prognostic factors for OS. Despite the presence of more poor prognostic factors for survival in the PET–CT group, the crude mortality rates of the pre-CCRT PET–CT and non-pre-CCRT PET–CT groups were 61.0% and 64.5%, respectively (Table In the multivariable analysis, we observed that age > 70 years [As shown in Table The strength of our study is that it is the first largest homogenous modality study on PET–CT including a long-term follow-up cohort to examine the survival outcomes of pre-CCRT This study has some limitations. First, because all the patients with p16-negative OPSCC were enrolled from an Asian population, the corresponding ethnic susceptibility compared with that of a non-Asian population remains unclear; hence, our results should be cautiously extrapolated to non-Asian populations. However, no evidence indicates differences in the survival outcomes of patients with p16-negative OPSCC receiving CCRT between Asian and non-Asian populations. Second, the toxicity scores have not been available in the TCRD. Third, the diagnoses of all comorbidities were based on ICD-10-CM codes. However, the combination of the TCRD and National Health Insurance Research Database in Taiwan appears to be a valid resource for population research on cardiovascular disease, stroke, or chronic comobidities [

Ethical considerations
ALBERT
The household questionnaire was only applied to adults who provided information related to the purpose of this study. No child or adolescent below the age of 18 was interviewed in this study. All people participating in the study were informed in local language through the study information sheet in a written and oral way. They were asked to sign the informed consent form. All participants were informed that their participation was voluntary and that their responses remained anonymous, therefore the study used numbers which replaced the names of individuals and codes which replaced the address of house. Before examining the domestic and peri-domestic water-holding containers, the field team requested permission to enter the house, did the inspection and collected entomological and sociodemographic data.The study received approval from local health authorities in Cucuta and Norte de Santander and the study protocol was approved by the ethical committee of the Albert–Ludwigs-Universität (application number 141/19) in Freiburg, Germany and the National Institute of Health in Bogota, Colombia.

Across all clusters, 2.0% (468/23,093) of household members reported to have had any arboviral disease (DZC) during the last 12 months (Dengue incidence was 0.84%). This ranged from 3.0% (116/3,814) in Los Patios, 2.3% (90/3,948) in Villa del Rosario, to 1.7% (262/15,331) in Cucuta. A small group of respondents (68 persons) assumed to have had mixed infections with two arbovirus diseases. The 12-months self-reported incidence was the following: dengue 841.6 per 100,000 inhabitants, Zika 585.3 per 100,000 inhabitants and chikungunya 572.45 per 100,000 inhabitants. Persons with dengue (83.2%) usually went for diagnosis and treatment to the hospital while persons with Zika or Chikungunya used much less the hospital services (45.3% and 57.5% respectively).

SECONDARY, CHAGAS DISEASE, LEISHMANIASIS
This study provides cluster specific information on socio-economic indicators and cluster size, on the estimated mosquito abundance, the main breeding places and their pupal productivity, the type and size of water containers, water use for drinking and cleaning which should be considered for the planning of the intervention (covering the productive water containers with a protective and transparent coating) and implementation of the CRT in randomly assigned clusters (using incidence rates and entomological indicators) into intervention and control clusters. The intervention in these ground tanks should be safe for human consumption as a small proportion of households (2.2%) uses the water is also for cooking and drinking. Moreover, people’s willingness to accept the insecticidal coating in their laundry tanks was high in all clusters (88.3%) based on the information, that a sub-study with water samples (to be presented in a different paper) showed no toxicity of the paint and will be delivered for free. Previous studies in Nepal and Bangladesh found that the application of insecticidal coating on house walls was safe and well accepted by communities and health workers. High acceptance (94%) of the households’ participants was reported in the control of leishmaniasis and Chagas disease [A specific challenge for assessing the effectiveness of vector control interventions is people’s mobility during the day as 40.3% of the people in our sample used to leave the cluster area during the day at least for some hours so that they can get infected in other places and bring the viruses home. Male, adult people (20 years and older) and people in secondary education had higher proportion of time spent outside their clusters. This finding is similar to a study in Mexico which found differences in human mobility according to gender and age [The novel insecticidal coating contains two active ingredients pyriproxyfen and alphacypermethrin which have both been widely evaluated for vector control. The concept of coating of surfaces with micro-encapsulated insecticidal/larvicidal products for vector control has gained special attention in comparison with other vector control methods such as insecticide-impregnated bednets, and indoor residual spraying [

Then, based on the random sequence that was prepared, the researcher assistant opened the containers sequentially, and the eighty patients under PCI were randomly divided into the intervention and control groups. Allocation concealment that prevents selection bias was implemented through a randomization for allocation to the two groups; we kept the random allocation sequence in a locked numbered containers, so the statistician and outcomes assessors were blind.

The intervention
heart disease
DISEASE, HEART DISEASE
In the interventional group, in addition to educational pamphlets and routine hospital care, telephone counseling was performed for 8 weeks. It was conducted by a MSc nurse that had 3 years of experience working as a nurse in CCU wards. Each patient gave us his/her contact number as well as that of a family member; the researcher gave them her contact number. They were provided with a schedule of telephone calls, which included 3 calls per week for 8-weeks. The average call time was 30 min. The range of contact time was from 8 A.M. to 9 P.M. In the case of any problems or questions, they were in contact with the researcher at the same time interval. The patient was referred to a physician to follow up on his/her questions and problems, if necessary.In the first telephone call, the Orem Needs Assessment was utilized to evaluate the client’s needs during the initial telephone call in the intervention group. This program incorporates distinctive aspects, including the identification of universal and health deviation self-care requisites, as well as promotion of the individuals’ independence and active engagement in self-care for maintaining the structural and functional integrity of a person [The care plan was designed and developed based on the goals in the form of a supporting education system that included: (1) Meeting the patient’s needs in self-care, (2) Making the patient responsible for self-care, and (3) Increasing the patient’s independence in care and his/her adaptation to the changes that have been made, etc. Therefore, the nurse here has an advisory role based on Orem’s supporting education system. For example, for a heart disease patient who has high blood cholesterol, the nurse helps the patient by educating him/her about a healthy diet such as reducing the consumption of saturated fats, losing weight, etc. by increasing awareness about their diet. Moreover, a patient with heart disease who had undergone angioplasty and his self-confidence had decreased due to the limitations, the nurse helped him to trust his abilities against the disease by focusing on the patient’s capabilities, strengthening positive behaviors, and improving the behavioral and mental performance of the patient to help him adapt to the disease and feel good despite the limitations [The content of telephone conversations generally included the researcher’s self-introduction, inquiring about the patient’s general health condition, giving healthcare advice, informing the patient about nutrition and medication, assessing the patient’s level of adherence to dietary and medication regimen, evaluating the behavioral objectives agreed upon by the patients and the researcher, reinforcing health behaviors, terminating the call with the words of encouragement, and arranging the next contact. During the telephone conversation, the researcher emphasized compliance with the plans and proposed possible solutions to the patient’s problems.

The control group received routine care without any interventions. The patients received the routine care as follows: educational pamphlets and standard hospital care including education about diet, activity, medications, and educational pamphlets about disease and medicine, and the way to see a doctor at the time of discharge were presented, but no pre-planned program was performed.

Adherence to treatment
Modanloo’s Chronic Patients Adherence Questionnaire was used to assess adherence to the treatment of heart patients in various dimensions (acceptance of medication, diet, weight control, physical activity, follow-up time for treatment, and lifestyle changes). This scale has 40 items in the form of 7 subscales in the areas of concern in treatment (9 questions), willingness to participate in treatment (7 questions), ability to adapt (7 questions), integration of treatment with life (5 questions), adherence to treatment (4 questions), commitment to treatment (5 questions), and management of treatment (3 questions). This questionnaire is scored based on 5-point Likert scale (strongly agree = 1, disagree = 2, neutral = 3, agree = 4, strongly agree = 5). The higher the total score or the score of each subscale, the higher the adherence of the respondent. In Modanloo’s study, the correlation coefficient test-retest was reported 0.87. The internal consistency was Cronbach’s alpha = 0.92 [

Resilience
cardiovascular and respiratory diseases
Resilience for patients with cardiovascular and respiratory diseases was designed by Ebadi et al. in 2016. This scale has 29 items with 5 subscales in the dimensions of positive adjustment (10 questions), self-management dimension (7 questions), rational empowerment dimension (7 questions), treatment adherence dimension (3 questions), and spirituality dimension (2 questions). This questionnaire is also scored based on a 5-point Likert scale (strongly disagree = 1, disagree = 2, neutral = 3, agree = 4, strongly agree = 5). The scores range from 29 to 145, so the higher the score, the more positive the patient’s resilience. Cronbach alpha coefficient for the whole questionnaire was 0.96. Also, the intra-class correlation coefficient was 0.95, based on the result of the re-test. The psychometrics of the questionnaire was assessed using face and content validity, internal consistency, and stability. The findings showed that the resilience questionnaire for patients with cardiovascular and respiratory diseases (Ebadi 2016) was valid and had a high level of reliability [

To describe the findings, we used the mean, frequency percentage, variance, and standard deviation. To determine the confounders and other factors that might be associated to adherence to treatment and resilience, we used multiple linear regression analysis. It showed that age, gender, marital status, educational level, job, BMI, having hypertension, diabetes, and hyperlipidemia, family history of heart disease, and history of smoking were not associated to adherence to treatment and resilience. The Kolmogorov-Smirnov test was used to check the normality of data distribution. The studied samples did not have a normal distribution. Statistical analysis (Chi-square test), as well as non-parametric tests (Wilcoxon, Mann-Whitney test), were used for intergroup and intragroup comparisons. The significance level in statistical tests was considered 0.05, and SPSS statistical software version 23 was used to analyze the data.

Sample characteristics
The final sample of 80 respondents was randomly assigned into two groups of 40, intervention and control subjects. The youngest participant in this study was 41 years old and the oldest was 65 years old, and the mean age of the participants was 56.60 ± 5.546 years. According to the Mann-Whitney test, there was no significant difference between the two groups in terms of age (P = 0.68). The majority of the subjects in both groups were male (61.3%) and married (83.8%). Most participants in the intervention and control groups (52.5%) had a diploma and were retired (32.5%). The results of the chi-square test showed that there was no significant difference between the two groups in terms of demographic characteristics including gender, marital status, education level, and job (P > 0.05). Details of the respondents are presented in Table The BMI of the participants was reported 25.65 ± 2.896. The means of their BMI were 25.85 ± 2.88, and 25.43 ± 2.92 in the intervention and control groups, respectively. The results showed no significant difference between the two groups in terms of BMI (Z=-4.63, P = 0.67) (Table According to the results shown in Table As shown in Table This study indicated that there was no statistically significant difference between the resilience mean scores of the two groups before the intervention (P = 0.92). On the other hand, the resilience mean score of patients in the intervention and control groups was statistically significant after the intervention (P < 0.001). The mean score of resilience inpatients of the intervention group before and after the intervention was significantly different (P < 0.001). There was a statistically significant difference in the resilience mean scores of patients in the control group before and after the intervention (P = 0.02); however, this difference was reduced in the control group.

Discussion
heart failure, cardiovascular diseases
HEART FAILURE, CARDIOVASCULAR DISEASES
The results of the study showed that there was a difference between the two groups in terms of adherence to treatment and resilience after the intervention. The results of the present study also showed that the mean scores of adherence to treatment and resilience were significantly different in the intervention group before and after the intervention, but they were not significantly different in the control group. According to the findings, adherence to treatment by patients after the intervention was more than that in pre-intervention treatment. Consistent with the present study, Oscalices et al. reported the effect of telephone follow-up and discharge instructions on the adherence to treatment of patients with heart failure [The results of this study showed a significant difference between the two groups in terms of resilience after the telephone counseling based on Orem’s model. According to the results, in the intervention group, the mean resilience after the intervention was significantly higher than that before the intervention. However, in the control group, the mean score of resilience decreased after the intervention compared to before it. Consistent with the present study, Studies have shown that cardiovascular diseases have lower scores in resilience dimensions than healthy people. Also, resilience decreases during time [In this study, the authors devised a care plan for individuals with heart conditions based on their self-care requirements. The plan included educating and guiding patients about their condition and the way to manage their medications as well as assisting them in developing and maintaining independence in self-care. The healthcare team worked closely with patients to identify any gaps or shortcomings in their self-care skills offering activities and interventions to address those areas effectively. Early encouragement of self-care was emphasized to facilitate the patients’ attainment of independence.Furthermore, nurses played a role in educating the patients about the techniques and strategies for self-care. They collaborated with patients to create care plans that catered specifically to their needs and goals. Emotional support was also provided throughout the process. Various efforts were made to meet these care needs while promoting autonomy, such as establishing a supportive environment that encouraged active patient participation in their own care activities. Regular progress assessments were conducted, allowing for adjustments to the care plans in order to instill confidence in patients.Using a specific questionnaire for measuring adherence to treatment in heart patients was one of the strengths of this study. However, it is suggested in another study that the indirect adherence to treatment should be assessed. For example, adherence to medications such as clopidogrel would be assessed by the number of drug administration, skipping administration, and incorrect times and doses. Adherence to diet would indirectly be assessed by some laboratory tests such as the level of cholesterol, triglycerides, LDL, and HDL. Moreover, adherence to the follow-up time for treatment would be assessed by the number of physicians missed.

Conclusion
DISEASE, COMPLICATIONS
The results of the present study showed that nursing counseling by telephone based on the Orem’s model increased the adherence to treatment and resilience of patients who had undergone coronary angioplasty. Therefore, mobile counseling, as an inexpensive method, can change the focus of the treatment and care from the clinic to the patient’s daily life. The widespread use of mobile phones has provided a promising opportunity to improve the care and self-management of heart patients. Nurses can also deal with the complications and effects of the disease by learning resilience methods and changing the patients’ attitudes about the stress caused by coronary angioplasty, thereby improving resilience in patients.

HYPOTENSIVE, SHOCK, SHOCK
Exploratory post-hoc analysis of the Angiotensin II for the Treatment of High-Output Shock (ATHOS-3) trial data. The ATHOS-3 trial randomized 321 patients with vasodilatory shock, who remained hypotensive (mean arterial pressure of 55–70 mmHg) despite receiving standard of care vasopressor support at a norepinephrine-equivalent dose (NED) > 0.2 µg/kg/min, to receive AT II or placebo, both in addition to standard of care vasopressors. Patients were grouped into low (≤ 0.25 µg/kg/min; n = 104) or high (> 0.25 µg/kg/min; n = 217) NED at the time of study drug initiation. The primary outcome was the difference in 28-day survival between the AT II and placebo subgroups in those with a baseline NED ≤ 0.25 µg/kg/min at the time of study drug initiation.

VASODILATORY SHOCK, SHOCK
Vasodilatory shock is the most common form of shock and can result in high rates of organ failure and death [Angiotensin II (AT II) is an endogenous peptide hormone and a component of the renin–angiotensin–aldosterone system (RAAS). This compound has a unique mechanism of action, distinct from those of catecholamines and vasopressin [Despite these observations, in the real-world setting, AT II has been initiated at much higher baseline vasopressor doses (i.e., > 0.5 µg/kg/min) than doses used in the ATHOS-3 trial (> 0.2 µg/kg/min), often as ‘salvage therapy’ leading to suboptimal outcomes [
