Calibration and XGBoost reweighting to reduce coverage and non-response biases in overlapping panel surveys: application to the Healthcare and Social Survey.

Background: Surveys have been used worldwide to provide information on the COVID-19 pandemic impact so as to prepare and deliver an effective Public Health response. Overlapping panel surveys allow longitudinal estimates and more accurate cross-sectional estimates to be obtained thanks to the larger sample size. However, the problem of non-response is particularly aggravated in the case of panel surveys due to population fatigue with repeated surveys.

Impact of COVID-19 on the Health of the General and More Vulnerable Population and Its Determinants: Health Care and Social Survey-ESSOC, Study Protocol.

This manuscript describes the rationale and protocol of a real-world data (RWD) study entitled Health Care and Social Survey (ESSOC, Encuesta Sanitaria y Social). The study's objective is to determine the magnitude, characteristics, and evolution of the COVID-19 impact on overall health as well as the socioeconomic, psychosocial, behavioural, occupational, environmental, and clinical determinants of both the general and more vulnerable population. The study integrates observational data collected through a survey using a probabilistic, overlapping panel design, and data from clinical, epidemiological, demographic, and environmental registries.

Laparoscopic Versus Open Incisional Hernia Repair: Long-Term Follow-up Results of a Randomized Clinical Trial.

Purpose: Long-term extension of a previous randomized controlled clinical trial comparing open (OVHR) vs. laparoscopic (LVHR) ventral hernia repair, assessing recurrence, reoperation, mesh-related complications and self-reported quality of life with 10 years of follow-up.

Methods: Eighty-five patients were followed up to assess recurrence (main endpoint), reoperation, mesh complications and death, from the date of index until recurrence, death or study completion, whichever was first.

Open randomized clinical trial of laparoscopic versus open incisional hernia repair.

Background: Incisional hernia is a common complication following abdominal surgery. Although the use of prosthetics has decreased recurrence rates, the standard open approach is still unsatisfactory. Laparoscopic techniques are an attempt to provide similar outcomes with the advantages of minimally invasive surgery.

[Adverse outcomes in the surgical treatment of acute appendicitis].

Objectives: To describe adverse outcomes after appendectomy for acute appendicitis and to analyze the association between these outcomes and specific characteristics of the patient and hospital admission.

Material And Methods: We studied a cohort of 792 patients who underwent appendectomy for acute appendicitis. Postoperative complications, reoperations and deaths were prospectively studied and all readmissions were retrospectively identified.
