Background: The success of body contouring surgery will largely depend on the correct choice and performance of the technique, and utilization of the necessary scientific measures. Thus, this study sought to highlight the combination and evolution of the abdominoplasty-assisted liposuction technique, while individualizing each case for the patient's benefit., Method: We present a series of 188 cases from the past 3 years (2017-2019), using our modification to the surgical technique: performing 360-degree liposuction first, and then abdominoplasty in the same surgical time. We show our aesthetic results, surgical time, and complications, so as to compare them with the literature., Results: Of the 188 cases, 184 were women (97.9%) and 4 were men (2.1%). In 11 cases (5.8%), we recorded 4 hours as a minimum surgical time and 8 hours in 16 cases (8.5%) as a maximum time. Regarding complications, hematomas were recorded in 1 case (0.5%) as the least frequent complication and seromas in 18 cases (9.6%) as the most frequent complication. The aesthetic results, although not objectively measurable, are flattering for both the patient and the surgeon, as shown by documented evidence (photographs) before and after surgery., Conclusions: Our study supports favorable results. Modification of this technique has resulted in outstanding body contouring surgery. We hope this procedure can be reproduced because of its few complications and the pleasant results it yields., Competing Interests: Disclosure: All the authors have no financial interest to declare in relation to the content of this article., (Copyright © 2021 The Authors.

Platelet concentrates (PCs) obtained from whole blood are produced by fractionation of the buffy coat (BC) or the platelet-rich plasma. Despite the improvements in the technologies used for the hemocomponent fractionation, the proportion of PCs that do not accomplish the quality requirements is high. This study aimed to determine whether the basal platelet and leukocyte counts are predictive factors of the quality of the PCs obtained from BC by semiautomated fractionation. Quality control registers of 196 PCs were analyzed. Gender- and age-dependence of the blood cell count and the characteristics of PCs were evaluated. Platelet yield and residual leukocytes in the PCs were correlated with the platelet and leukocyte counts and the age of the donors. Predictive efficacy was assessed, and an optimal cut-off was established. The proportions of PCs accepted and rejected by using or not the optimal cut-off were compared. 50.0% of the PCs accomplished all the quality control requirements. Female donors had a higher basal platelet count than males. A correlation was observed between basal platelets and platelet yield, but not between basal leukocytes and residual leukocytes. The basal platelet count predicted the quality of the PCs. A cut-off of 231,000 platelets/mm 3 was established, but it did not improve the proportion of accepted PCs. In conclusion, we found that the basal platelet count is correlated with the platelet yield. The basal leukocyte count is not correlated with the residual leukocytes. The established cut-off for the basal platelet count did not improve the proportion of accepted PCs., (Copyright © 2020 Elsevier Ltd. All rights reserved.)

Introduction: Algorithms have been developed to predict the platelet yield after apheresis from the donor's data, as well as the effect on the blood cell count, to extract an acceptable platelet number without affecting the donor. However, the evaluation of these algorithms has not been widely reported. This study aimed to assess the accuracy of the predictive algorithms of the Trima Accel v. 6 blood collection system., Methods: Platelet concentrates (PCs) obtained by apheresis were analyzed. Platelet count and hematocrit were compared pre- and post-apheresis. Calculated post-apheresis platelet count (CPAPC), hematocrit (CPAH), and platelet yield (CPY), and their actual values were correlated. The bias of the algorithms was assessed with Bland-Altman plots, and the prediction of the extraction of single or double platelet products was evaluated., Results: Two hundred and seventy-nine PCs were analyzed. Post-apheresis platelet count (PAPC) and hematocrit were decreased. A moderate correlation was observed between CPY and the actual yield, with a negative bias, and a trend to increase alongside the magnitude of the measurements. CPAPC and CPAH were strongly correlated with their actual values without bias. Prediction of single or double platelet product extraction showed a significant agreement with the actual outcomes., Conclusions: The predictive algorithm for the platelet yield showed bias, and a trend to underestimate the actual platelet yields when they are higher. The algorithms for the prediction of the PAPC and hematocrit did not show bias, proving their accuracy. Prediction of a single or double platelet product extraction has a strong agreement with the APY., (© 2020 Wiley Periodicals LLC.)

Over the centuries, our appreciation of beauty has changed, as has the social environment that influences our perspective. Currently we are trying to use measurable instruments to achieve a better aesthetic result in each patient, using as a reference the "golden ratio," which is found in harmonies of all kinds-in art, nature, architecture, and today, in medicine-to aspire to the ideal proportion., Methods: We conducted a survey in which we showed participants 4 digitally modified images of a model with different body proportions, 1 with the golden ratio and 3 with other variable proportions. In total, 900 people were surveyed, of which 131 had attended cosmetic surgery consultation, and 769 respondents were recruited on our social networks., Results: Of the 900 respondents, 607 were women and 293 were men. Fifty-nine percent of the surveyed women chose image C (shown in Fig. 3) and similarly, so did 59.4% of surveyed men, which was not statistically significant; however, when considering age, we found the groups of 21-30, 31-40, and 41-50 chose image C at 46%, 65%, and 67%, respectively, whereas 44% of those over 51 years preferred image B, which is statistically significant., Conclusions: The image whose waist-hip harmony meets the golden ratio (1.61) is most often chosen as "the most beautiful," by both men and women. It is also the preferred image for all age groups under 50., (Copyright © 2020 The Authors. Published by Wolters Kluwer Health, Inc. on behalf of The American Society of Plastic Surgeons.)

The residual risk of transfusion-related infections has decreased dramatically in countries that have routinely implemented serological screening. Most of the donation in Mexico is from replacement practice, a risk factor for positive serology. In Mexico, the altruistic donation is only 2.7%. The heterogeneity of technical factors, regional factors and internal policies of each center influences the variability of data on the prevalence of positive screening, as well as the prevalence of confirmed cases. The main advantage of nucleic acid technology is the detection of donors in the period of serological window or occult infections, being occult hepatitis reports in Mexican donors from 1 to 3.4%. The limitation of available technology, the scope of the clinic and perspectives, invites us to improve technology and health policies in the interest of transfusion safety.

The genus Raoultella, which belongs to the Enterobacteriaceae family, encompasses gramnegative, oxidase-negative, aerobic, encapsulated and motionless bacilli. Currently, four species of this genus have been described: Raoultella terrigena (R. terrigena), Raoultella planticola (R. planticola), Raoultella ornithinolytica (R. ornithinolytica) and Raoultella electrica (R. electrica), out of which R. planticola and R. ornithinolytica are the most important because of their probable association as pathogenic agents. The incidence of this genus has been underestimated, given that detecting it is really difficult, since it is misidentified as Klebsiella spp. by using manual and automated conventional phenotypic methods. The rapid and correct detection has been increasing since the advent of mass spectrometers (MALDI-TOF MS), which have been used for the differentiation of Klebsiella spp. and Raoultella spp. Currently 80 cases of bacteremia secondary to Raoultella spp. have been identified with different sites of primary infection, which is why it is important to emphasize proper detection in hospitals and healthcare facilities.

Background and Aims: Cellular and animal models investigating extremely low frequency magnetic fields (ELF-MF) have reported promotion of leukocyte-endothelial interactions, angiogenesis, myofibroblast and keratinocyte proliferation, improvement of peripheral neuropathy and diabetic wound healing. In humans, it has also been reported that systemic exposure to ELF-MF stimulates peripheral blood mononuclear cells, promoting angiogenesis and healing of chronic leg ulcers. The aim of the study was to investigate the effect of exposing different blood volumes to specific ELF-MFs (120 Hz sinusoidal waves of 0.4-0.9 mT RMS) to induce healing of diabetic foot ulcers (DFUs)., Methods: Twenty six diabetic patients with non-responsive DFUs were divided into two exposure groups to receive treatment and record healing time. The forearm group, exposed to ELF-MF 2 h/day, twice weekly (3.6 l of blood/session); and the thorax group, exposed 25 min/day, 2 times/week (162.5 l of blood/session). Treatment period was 100 days or upon complete healing. Ulcer recurrences and adverse effects were investigated during short-term (<1 year) and long-term (3.4-7.8 years) follow-up., Results: Mean healing time was 61.48 ± 33.08 days in the forearm group and 62.56 ± 29.33 days for the thorax group. No adverse effects or ulcer recurrences in the original ulcer site were reported during treatment, the short-term follow-up period or the long-term follow-up period in both groups., Conclusions: Healing time was independent of the amount of blood exposed to ELF-MF used in this trial. ELF-MFs are effective and safe and could be applied to non-healing DFUs in conjunction with other preventive interventions to reduce DFUs complications., (Copyright © 2015 IMSS.

The prehispanic medicines of Mexico are considered as testimony of the splendor of the Meso-American cultures; their great scientific advance and technical allowed them to accumulate a vast collection of clinical and pathological data based on the observation and experimentation. They integrated a nomenclature medical surgical that reflected their advance in those fields of the knowledge, where the anatomy and surgery occupied a preponderant paper. The medicine was known generically as ticiotl, of where it derives the term tícitl for the doctor. In their concept health-illness the limits among the magic, religion and the empiricism for natural causes were not clear, therefore they considered that the divine, human or natural origin of the illnesses influenced in an important way in its nature. Inside this complex causal system, the illnesses caused by the gods, spirits and celestial beings were considered as hot, while those caused by beings of the other realm were cold. The practice of the medicine had a very established organization designing a very advanced system of specialties that allowed them to accumulate a vast experience for the handling of chronic and acute illnesses in different progression phases, which managed with an integral therapy that had a plurality of resources of vegetable origin, animal, and mineral. The surgery was designated as texoxotlaliztli and its cures tepatiliztli. The surgeon was designated as texoxotlaticitl and it developed advanced techniques in the handling of sutures, wounded, drainage of abscesses, fractures and joint dislocations, pterygium, tonsillitis, circumcision, and amputations.
