[Learning concepts of diagnosis in family medicine: the "mark robinson sign" - the traces that should not be there]. / Aprendiendo conceptos del diagnóstico en medicina de familia: a propósito del «signo de Robinson¼ - las huellas que no deberían estar allí.

We review the mechanisms of the mental operation to identify the disease in family medicine, using five cases where the diagnosis process began in "the trace that should not be there" or "Robinson sign" as happened to Robinson Crusoe when he saw a human footprint on the beach of the "desert island". How could it be there?; It was a mystery, and based on metaphors, we framed the mechanism of "the trace that should not be there" mainly in the first phase of clinical or intuitive reasoning, but this intuition of the doctor should be accompanied by the diagnostic process, like the "basso continuo" of Baroque music, allowing improvisation and personal style, and in this way, eventually observing the footprint "that should not have been there" that may arise in the analytical, as well as in the verification phase of the assumptions made.

Carprofen Attenuates Postoperative Mechanical and Thermal Hypersensitivity after Plantar Incision in Immunodeficient NSG Mice.

Immunodeficient NSG mice are reported to be less responsive to buprenorphine analgesia. Here, we used NSG mice to compare the efficacy of the commonly used dose of carprofen (5 mg/kg) with 5 and 10 times that dose (25 and 50 mg/kg) for attenuating postoperative mechanical and thermal hypersensitivity following an incisional pain model. Male and female NSG mice (n = 45) were randomly assigned to one of 4 groups and received daily subcutaneous injections for 3 d: saline (5 mL/kg), 5 mg/kg carprofen (Carp5), 25 mg/kg carprofen (Carp25), and 50 mg/kg carprofen (Carp50). Mechanical and thermal hypersensitivity were assessed 24 h before and at 4, 24, and 48 h after surgery. Plasma carprofen concentrations were measured in a separate group of mice (n = 56) on days 0 (at 2, 4, 12, and 23 h), 1, and 2 after the first, second, and third doses, respectively. Toxicity was assessed through daily fecal occult blood testing (n = 27) as well as gross and histopathologic evaluation (n = 15). Our results indicated that the saline group showed both mechanical and thermal hypersensitivity throughout the study. Carp5 did not attenuate mechanical or thermal hypersensitivity at any time point. Carp25 attenuated mechanical and thermal (except for the 4-h time point) hypersensitivity. Carp50 attenuated only thermal hypersensitivity at 24 h. Fecal occult blood was detected in 1 of 8 Carp25-treated mice at 48 and 72 h. Histopathologic abnormalities (gastric ulceration, ulcerative enteritis, and renal lesions) were observed in some Carp50-treated mice. Plasma carprofen concentrations were dose and time dependent. Our results indicate that Carp25 attenuated postoperative mechanical and thermal hypersensitivity more effectively than Carp5 or Carp50 in NSG mice with incisional pain. Therefore, we recommend providing carprofen at 25 mg/kg SID for incisional pain procedures using immunodeficient NSG mouse.

High Shear Stress Reduces ERG Causing Endothelial-Mesenchymal Transition and Pulmonary Arterial Hypertension.

Pathological high shear stress (HSS, 100 dyn/cm 2 ) is generated in distal pulmonary arteries (PA) (100-500 µm) in congenital heart defects and in progressive PA hypertension (PAH) with inward remodeling and luminal narrowing. Human PA endothelial cells (PAEC) were subjected to HSS versus physiologic laminar shear stress (LSS, 15 dyn/cm 2 ). Endothelial-mesenchymal transition (EndMT), a feature of PAH not previously attributed to HSS, was observed. H3K27ac peaks containing motifs for an ETS-family transcription factor (ERG) were reduced, as was ERG-Krüppel-like factors (KLF)2/4 interaction and ERG expression. Reducing ERG by siRNA in PAEC during LSS caused EndMT; transfection of ERG in PAEC under HSS prevented EndMT. An aorto-caval shunt was preformed in mice to induce HSS and progressive PAH. Elevated PA pressure, EndMT and vascular remodeling were reduced by an adeno-associated vector that selectively replenished ERG in PAEC. Agents maintaining ERG in PAEC should overcome the adverse effect of HSS on progressive PAH.

[The symptoms in family medicine are not symptoms of disease, they are symptoms of life]. / Los síntomas en medicina de familia no son síntomas de enfermedad, sino síntomas de vida.

The symptoms in family medicine are not signs of disease, but "signs of life"; in the consultation "all patient life comes together with him". Every consultation is primarily a biopsicosocial problem: the person perceives a dysfunction or alteration in relation with himself and his context. To do a diagnosis only with physical symptoms, can be a mistake because these do not identify the real problem. The different types of symptoms are "entangled" or chained some in others: the symptoms can be fitted or inevitable; to be expressions of biochemical alterations, symbols for the patient, group context expressions, or kinds of facing the facts; and they depend on the previous psychological patient performance, the severity of the deficit of the psychological function associated with the disease, the residual skills, the adjustment and the confrontation of the functional limitations, the relation doctor-patient, as well as on the influence of the context.

Extended-release Buprenorphine, an FDAindexed Analgesic, Attenuates Mechanical Hypersensitivity in Rats (Rattus norvegicus).

A new extended-release buprenorphine (XR), an FDA-indexed analgesic, has recently become available to the laboratory animal community. However, the effectiveness and dosing of XR has not been extensively evaluated for rats. We investigated XR's effectiveness in attenuating postoperative hypersensitivity in a rat incisional pain model. We hypothesized that high dose of XR would attenuate mechanical and thermal hypersensitivity more effectively than the low dose of XR in this model. We performed 2 experiments. In experiment 1, male adult Sprague-Dawley rats (n = 31) were randomly assigned to 1 of the 4 treatment groups: 1) saline (saline, 0.9% NaCl, 5 mL/kg, SC, once); 2) sustained-release buprenorphine (Bup-SR; 1.2 mg/kg, SC, once), 3) low-dose extended-release buprenorphine (XR-Lo; 0.65 mg/kg, SC, once), and 4) high-dose extended-release buprenorphine (XR-Hi; 1.3 mg/kg, SC, once). After drug administration, a 1 cm skin incision was made on the plantar hind paw under anesthesia. Mechanical and thermal hypersensitivity were evaluated 1 d before surgery (D-1), 4 h after surgery (D0), and for 3 d after surgery (D1, D2, and D3). In experiment 2, plasma buprenorphine concentration (n = 39) was measured at D0, D1, D2, and D3. Clinical observations were recorded daily, and a gross necropsy was performed on D3. Mechanical and thermal hypersensitivity were measured for 3 d (D0-D3) in the saline group. Bup-SR, XR-Lo, and XR-Hi effectively attenuated mechanical hypersensitivity for D0-D3. Plasma buprenorphine concentrations remained above 1 ng/mL on D0 and D1 in all treatment groups. No abnormal clinical signs were noted, but injection site reactions were evident in the Bup-SR (71%), XR-Lo (75%), and XR-Hi (87%) groups. This study indicates that XR-Hi did not attenuate hypersensitivity more effectively than did XR-Lo in this model. XR 0.65 mg/kg is recommended to attenuate postoperative mechanical hypersensitivity for up to 72 h in rats in an incisional pain model.

Adjuvanting a subunit SARS-CoV-2 vaccine with clinically relevant adjuvants induces durable protection in mice.

Adjuvants enhance the magnitude and the durability of the immune response to vaccines. However, there is a paucity of comparative studies on the nature of the immune responses stimulated by leading adjuvant candidates. In this study, we compared five clinically relevant adjuvants in mice-alum, AS03 (a squalene-based adjuvant supplemented with α-tocopherol), AS37 (a TLR7 ligand emulsified in alum), CpG1018 (a TLR9 ligand emulsified in alum), O/W 1849101 (a squalene-based adjuvant)-for their capacity to stimulate immune responses when combined with a subunit vaccine under clinical development. We found that all four of the adjuvant candidates surpassed alum with respect to their capacity to induce enhanced and durable antigen-specific antibody responses. The TLR-agonist-based adjuvants CpG1018 (TLR9) and AS37 (TLR7) induced Th1-skewed CD4+ T cell responses, while alum, O/W, and AS03 induced a balanced Th1/Th2 response. Consistent with this, adjuvants induced distinct patterns of early innate responses. Finally, vaccines adjuvanted with AS03, AS37, and CpG1018/alum-induced durable neutralizing-antibody responses and significant protection against the B.1.351 variant 7 months following immunization. These results, together with our recent results from an identical study in non-human primates (NHPs), provide a comparative benchmarking of five clinically relevant vaccine adjuvants for their capacity to stimulate immunity to a subunit vaccine, demonstrating the capacity of adjuvanted SARS-CoV-2 subunit vaccines to provide durable protection against the B.1.351 variant. Furthermore, these results reveal differences between the widely-used C57BL/6 mouse strain and NHP animal models, highlighting the importance of species selection for future vaccine and adjuvant studies.

Observaciones, intuiciones y anécdotas, desde la perspectiva del médico, para una teoría de la historia natural de la continuidad interpersonal. Los colores del tiempo / Observations, insights and anecdotes from the perspective of the physician, for a theory of the natural history of interpersonal continuity. The colors of time

Se aportan elementos para una teoría de la historia natural de la continuidad interpersonal, desde la perspectiva del médico de familia, analizada en base a la reflexión y el recuerdo de dos médicos respecto a su relación con sus pacientes durante 30 años en que han trabajado en el mismo lugar. Es un viaje por los “colores de la historia natural de la continuidad interpersonal”, que cambian al paso del tiempo. Se observa un escenario de demanda creciente cada vez más trivial, con una falta de comprensión por parte del paciente de lo que constituye una buena calidad científico técnica y una comunicación con el médico inapropiada, con una defensa cognitiva y conductual del médico. Podrían describirse distintas tipologías de continuidad interpersonal, que se combinan a lo largo del tiempo, y que esta podría ser discontinua, y experimentarse como “momentos”, presentando efectos positivos y negativos (AU)

Elements for a theory of natural history of interpersonal continuity are provided, from the perspective of the family doctor, analyzed on the reflection and remembrance of two doctors regarding their relationship with their patients during 30 years working in the same place. It is a journey through the “colors of the natural history of interpersonal continuity”, which change over time. A scenario of increasingly trivial growing demand is observed, with a lack of understanding by the patient of what constitutes a good scientific and technical quality and an inappropriate communication with the doctor, which causes a cognitive and behavioral defense from the family doctor. They may describe different types of interpersonal continuity, which combine over time, and that it could be discontinuous, and experienced as “moments”, presenting positive and negative effects (AU)

Aprendiendo conceptos del diagnóstico en medicina de familia: a propósito del "signo de Robinson" - las huellas que no deberían estar allí / Learning concepts of diagnosis in family medicine: the “mark robinson sign” - the traces that should not be there

A propósito de cinco casos en donde el proceso diagnóstico se inició en 'la huella que no debería estar allí' o 'signo de Robinson' -como le pasó a Robinson Crusoe que vio una huella humana en la playa de su isla 'desierta': ¿cómo podía encontrarse allí?; era un misterio-, y basándonos en metáforas, revisamos los mecanismos de la operación mental de identificar la enfermedad en medicina de familia. Encuadramos el mecanismo de 'la huella que no debería estar allí' principalmente en la primera fase o intuitiva del razonamiento clínico, pero esta intuición del médico debe mantenerse acompañando a todo el proceso diagnóstico, como el 'bajo continuo' de la música barroca, permitiendo la improvisación y el estilo personal, y de este modo, eventualmente la observación de la huella 'que no tenía que estar allí' puede surgir tanto en la fase analítica como en la de verificación de las hipótesis elaboradas
