Este artículo muestra los resultados de un experimento con un test (llamado cognitive reflection test ―CRT por sus siglas en inglés y cuya traducción puede ser “prueba de reflexión cognitiva”) diseñado por Shane Frederick, profesor de mercadotecnia en la Universidad de Yale. Se realizaron una serie de encuestas a estudiantes de varias universidades norteamericanas (entre ellas el MIT, la Universidad de Princeton, Carnegie Mellon y Harvard) con el objetivo de averiguar qué tipo de razonamiento sigue una persona al enfrentarse a un problema en su vida cotidiana.
Se describe uno de los primeros casos documentados de percepción multisensorial: lo que desde entonces se denomina “efecto McGurk”. Si vemos un video sin sonido donde una persona vocaliza y repite la sílaba “ga” y simultáneamente escuchamos una grabación de esa misma persona que pronuncia la sílaba “ba”, lo que oímos es que pronuncia la sílaba “da”. Las “ga” mudas alteran nuestra percepción de las “ba” sonoras porque el cerebro integra lo que vemos y oímos al mismo tiempo
Este artículo expone la idea de que las operaciones neocorticales son multisensoriales, es decir, suponen la integración de información de múltiples fuentes sensitivas

Familial Mediterranean Fever (FMF) is an autoinfl ammatory disease caused by mutations in the MEFV
gene and characterized by recurrent fever, polyserositis and arthritis. It is transmitted in an autosomal
recessive pattern. FMF has been predominantly found in ethnic groups living around the Mediterranean
basin (Jews, Arabs, Turks, and Armenians). Although accompanying infl ammatory diseases have been
reported in FMF, the coexistance of fi bromyalgia syndrome (FMS) is very rare. MEFV gene analysis that the
fi rst patient had compound heterozygous mutation (M680I+V726A) and the other patient had heterozygous
mutation (M694V). This association will be discussed in this case report.

mutation(s) in the Mediterranean fever (MEFV, pyrinmarenostrin) gene. FMF is characterized by
recurrent fever crisis combined with serosal, synovial, or cutìaneous inflammation. Until now more
than 304 sequence variants have been recorded. Here, we describe a case of mild FMF confirmed
by analysis of the MEFV gene, characterized by polymorphism c1588-69G>A. The patient had a
good answer to the treatment with colchicine, that, unfortunately, he stopped for severe gastrointestinal side effects. The detection of polymorphism for intron 5 c1588-69G>A is not rare, since it
was also detected in healthy subjects, and the observation seem to suggest that this polymorphism
is associated with a symptomatic pour severe form and other factors can act as triggering factors of
symptoms.

The evolutionary history of the hominin hand since the last common ancestor o...José Luis Moreno Garvayo
Tocheri y colaboradores sostienen que las pruebas moleculares y fósiles tienen importantes consecuencias para la interpretación de la historia evolutiva de la mano dentro de la tribu Hominini. En primer lugar, la parsimonia apoya la hipótesis de que la mano del último ancestro común de los humanos y chimpancés es más probable que es pareciera a la de un gran simio actual en general (Pan, Gorilla, y Pongo), que a la de un simio africano en particular. En segundo lugar, proporciona un contexto para la interpretación de los cambios derivados de la mano que se han desarrollado en diferentes homínidos. Sin embargo, la mayoría de las características primitivas que es probable que estuvieran presentes en el último ancestro común de Pan y Homo se mantienen en las manos de Australopithecus, Paranthropus/primeros humanos, y Homo floresiensis.
Análisis de las proporciones internas de la mano (la longitud de los huesos largos del pulgar y el cuarto dedo) en relación con el tamaño corporal de una muestra de primates actuales y extintos. La muestra la conforma un total de 274 primates entre los que se incluyen macacos, mandriles, gibones, orangutanes, gorilas, chimpancés y Homo sapiens; además de algunas especies extintas de homininos (Ardipithecus ramidus, Australopithecus sediba y Homo neanderthalensis).
El principal objetivo de este trabajo ha consistido en establecer una cronología y datación precisas de los yacimientos Musterienses de Eurasia, ya que éstos contienen las mejores pruebas de la sustitución de un grupo humano (los Neandertales) por otro (AMHs)

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

DISSERTATION on NEW DRUG DISCOVERY AND DEVELOPMENT STAGES OF DRUG DISCOVERYNEHA GUPTA
The process of drug discovery and development is a complex and multi-step endeavor aimed at bringing new pharmaceutical drugs to market. It begins with identifying and validating a biological target, such as a protein, gene, or RNA, that is associated with a disease. This step involves understanding the target's role in the disease and confirming that modulating it can have therapeutic effects. The next stage, hit identification, employs high-throughput screening (HTS) and other methods to find compounds that interact with the target. Computational techniques may also be used to identify potential hits from large compound libraries.
Following hit identification, the hits are optimized to improve their efficacy, selectivity, and pharmacokinetic properties, resulting in lead compounds. These leads undergo further refinement to enhance their potency, reduce toxicity, and improve drug-like characteristics, creating drug candidates suitable for preclinical testing. In the preclinical development phase, drug candidates are tested in vitro (in cell cultures) and in vivo (in animal models) to evaluate their safety, efficacy, pharmacokinetics, and pharmacodynamics. Toxicology studies are conducted to assess potential risks.
Before clinical trials can begin, an Investigational New Drug (IND) application must be submitted to regulatory authorities. This application includes data from preclinical studies and plans for clinical trials. Clinical development involves human trials in three phases: Phase I tests the drug's safety and dosage in a small group of healthy volunteers, Phase II assesses the drug's efficacy and side effects in a larger group of patients with the target disease, and Phase III confirms the drug's efficacy and monitors adverse reactions in a large population, often compared to existing treatments.
After successful clinical trials, a New Drug Application (NDA) is submitted to regulatory authorities for approval, including all data from preclinical and clinical studies, as well as proposed labeling and manufacturing information. Regulatory authorities then review the NDA to ensure the drug is safe, effective, and of high quality, potentially requiring additional studies. Finally, after a drug is approved and marketed, it undergoes post-marketing surveillance, which includes continuous monitoring for long-term safety and effectiveness, pharmacovigilance, and reporting of any adverse effects.
Muktapishti is a traditional Ayurvedic preparation made from Shoditha Mukta (Purified Pearl), is believed to help regulate thyroid function and reduce symptoms of hyperthyroidism due to its cooling and balancing properties. Clinical evidence on its efficacy remains limited, necessitating further research to validate its therapeutic benefits.

2. An increasing number of interleukin-1 targeting drugs
are currently in various stages of development. Anakinra,
a recombinant, nonglycosylated homolog of the human
IL-1 receptor antagonist, competitively inhibits binding
of IL-1␣ and IL-1 to the IL-1 receptor. Other drugs
include longer acting molecules such as canakinumab, a
human IgG1 monoclonal antibody directed against IL-
1, and rilonacept, an IL-1 blocker that comprises the
extracellular domain of the human type 1 IL-1 receptor
coupled to a human IgG1 antibody. None of them are
licensed for use in FMF patients.
Here, we present 7 FMF patients who were treated
with anakinra and/or canacinumab. Based on these cases
and those published by others, we discuss the possible
indications of interleukin-1 targeting drugs in FMF pa-
tients and review the literature.
METHODS
Electronic mailing lists of French pediatric and adult
rheumatologists societies were used to call for the medical
history of FMF patients (confirmed by carriage of 2
MEFV-mutations) who had been treated with interleu-
kin-1 targeting drugs. Information about age, sex, disease
course, treatment before anti-IL-1 targeting drugs, rea-
sons for the use of anti-IL-1 targeting drugs, treatment
modalities, clinical effect, side effects, and duration of
follow-up were recorded. As the genetic analyses were
performed as routine diagnosis procedure, there was no
requirement for institutional review board approval.
They included the E148Q variant in exon 2 and exon 10
sequencing of the MEFV gene. When a single mutation
was identified in exon 2 or 10, exons 2, 3, and 5 were
also systematically sequenced as described elsewhere
(8). As both anakinra and canakinumab were given
off-label for use in FMF, patients received comprehen-
sive information and gave their consent before receiv-
ing these treatments.
To identify publications reporting FMF patients
treated with interleukin-1 targeting drugs, we searched
PubMed using the search term “FMF” alone or in com-
bination with 1 of the following terms: “anakinra,”
“interleukin-1,” “canakinumab,” “rilonacept.”
RESULTS
Seven patients (4 male, 3 female) from 5 different hospi-
tals were identified. The patients’ ages when starting IL-1
targeting drugs were 51, 45, 12, and 7 years (4 patients).
Disease duration before the use of interleukin-1 targeting
drugs was 3 to 6 years in children and approximately 20
years in adult patients. MEFV gene analyses showed ho-
mozygote M694V mutations in 6 patients and composite
I692de/V726A, E149Q mutations in 1 patient (case 4).
FMF manifested with fever and abdominal pain in all
patients, thoracic pain (case 1), myalgia (case 6). The
patients’ clinical features are summarized in Table 1.
They were all treated with colchicine (1-2 mg/d) and
treatment was continued under interleukin-1 targeting
drugs in all patients except case 1. Six patients were
treated with anakinra and 1 patient with canakinumab.
One patient initially treated with anakinra was later
switched to canakinumab. Treatment modalities are
shown in Table 1. The reasons for using interleukin-1
targeting drugs in FMF patients were as follows: frequent
and severe FMF episodes despite colchicine treatment (2
patients); high serum amyloid A (SAA) levels despite col-
chicine treatment (2 patients); impossibility to use
colchicine treatment because of colchicine-induced toxic
neuromyositis (1 patient); FMF associated severe He-
noch-Schonlein purpura (HSP) (1 patient); and an atyp-
ical FMF episode with severe myalgia and generalized
convulsions (1 patient). The use of interleukin-1 targeting
drugs was beneficial to all patients (complete remission in
6 patients, partial remission in 1 patient). Observed ad-
verse effects were injection site reactions (3 patients) and
moderate headache (1 patient).
PubMed screen identified 8 single case reports of
FMF patients (5 adults, 3 children) treated with inter-
leukin-1 targeting drugs (9-16) (Table 2). MEFV gene
analyses were recorded in 6 patients. Five patients car-
ried homozygote M694V mutations (9,11,12,14,16)
and 1 patient carried heterozygote E148Q mutations
(10). All patients were treated with subcutaneous anak-
inra injections. In 2 patients anakinra was initially ad-
ministrated every 48 hours and later increased to daily
injections. In 1 patient who underwent hemodialysis
because of end-stage renal failure, anakinra was given 3
times weekly after hemodialysis (12). In another pa-
tient anakinra was administrated only on demand,
promptly after the onset of FMF episodes (9). The
reasons for using Anakinra were as follows: recurrent
FMF episodes with or without amyloidosis (6 patients)
(9-13,16); FMF associated with Behçet’s disease (1 pa-
tient) (14); pneumonitis in a renal transplanted patient
(1 patient) (15). The response to anakinra treatment
was complete remission in 6 patients and partial remis-
sion in 2 patients (9,13). Local injection site reactions
were the only observed side effects.
DISCUSSION
Here, we report 7 FMF patients who were treated with
interleukin-1 targeting drugs. Additionally, in the litera-
ture 8 single cases have been published (9-16). Consider-
ing all published cases, the reasons for using interleukin-1
targeting drugs in FMF patients can be divided into the
following categories: (1) incomplete control of FMF dis-
ease activity despite colchicine treatment; (2) high SAA
levels and/or renal complications despite colchicine treat-
ment; (3) impossibility to use colchicine for the treatment
of FMF because of severe side effects; (4) FMF in associ-
ation with vasculitis.

4. Incomplete Control of Disease
Activity Despite Colchicine Treatment
The daily application of colchicine is the standard therapy
for prophylaxis of FMF attacks and amyloid deposition in
FMF. The beneficial role of colchicine for FMF attacks is
well documented by open-labeled studies in adult and
pediatric patients as well as placebo-controlled trials in
adult patients (17). Long-term application of colchicine
leads to a complete remission in two thirds of the patients
and partial remission (defined by significant decrease of
attack frequency or remission of a single symptom) in
approximately one third of the patients with FMF (17).
However, a minority of approximately 5 to 10% of the
patients does not respond to colchicine treatment (17). In
the latter, frequent and severe FMF attacks may severely
compromise the quality of life and increase the risk for
secondary amyloidosis. For example, insufficient disease
control with respect to severity and frequency of episodes
was the reason for introducing anakinra in cases 2 and 3 of
this report, as well as for most of the published single
cases. Anakinra for the treatment of colchicine-resistant
FMF has also been reported to be efficacious and safe in 2
adult patients with hemodialysis and/or renal transplan-
tation (12,16). This indication may represent the most
common situation for considering treatment of FMF
with anti-IL-1 targeting drugs.

5. Impossibility to Use
Colchicine because of Adverse Effects
Treatment with colchicine is generally safe and well tol-
erated. Most adverse effects to colchicine such as diarrhea
or nausea are mild to moderate and generally respond to
dose adaptation (17). Risk factors for toxicity of colchi-
cine treatment, such as renal impairment and drug asso-
ciation (eg, cyclosporine and macrolids), have been
described (18). Recommendations for the use of colchi-
cine have been addressed by Kallinich and coworkers (17)
and are regularly followed in our country. However, in
some patients severe adverse effects occur despite regular
prophylactic dosage, good patient compliance, and ab-
sence of risk factors. In case 1, for example, the patient
developed colchicine-induced neuromyositis.
Other rare adverse effects of colchicine susceptible to
impose treatment discontinuation and requirement of al-
ternative therapeutic approaches include bone marrow
alterations and dermatologic reactions (17).
High Serum Amyloid A Levels and/or Renal
Complications Despite Colchicine Treatment
The most important long-term complication of FMF is
progressive systemic type AA amyloidosis (1,2). The
localization is predominantly renal leading to chronic
renal failure but amyloidosis may also occur in other
sites such as gut, heart, endocrine glands, the spleen,
and the liver. AA amyloid fibrils are processed from the
acute phase reactant SAA protein (19). The SAA pro-
duction is highly correlated to amyloid burden and
renal dysfunction (20) and may therefore be used to
evaluate the risk for systemic amyloidosis. In cases 4
and 5 the constantly high SAA levels, even during the
symptom-free periods, indicated a high risk for the
development of systemic AA amyloidosis, and case 5
had additionally a positive family history of amyloido-
sis. In both cases the treatment with anakinra normal-
ized the SAA levels. Similarly, anakinra treatment
decreased the SAA levels of an adult patient with end-
stage renal failure (12). Together these reports indicate
that anakinra may be beneficial for decreasing the risk
of systemic AA amyloidosis in FMF patients with high
risk.
FMF Complicated by
Association with Other Diseases
FMF may be associated with other diseases and some-
times it is difficult to distinguish atypical FMF symptoms
from the associated disease. Whether FMF association to
other diseases results from a common causal factor or a
common pathomechanism remains to be explored. How-
ever, the higher frequency of FMF associated MEFV
mutations in some of the associated diseases is an obser-
vation that supports this theory. Thus, it is appealing to
think that controlling FMF may also be beneficial for the
control of the associated disease and vice versa.
In case 6 the patient presented with severe, protracted
myalgia and generalized convulsions. FMF-associated
convulsions are a rare, atypical disease manifestation that
has been described previously (21). Myalgia is present in
approximately 20% of FMF patients and may be classified
in spontaneous myalgia, exercise-induced myalgia, and
protracted myalgia syndrome (PFMS), which differ in
severity of pain, height of fever, and duration of the epi-
sode (22). Unless treated, the PFMS usually lasts for
weeks. In this patient, intensifying the colchicine treat-
ment with anakinra injections helped to rapidly control
PFMS.
In contrast, the motivation for the use of anakinra in
case 1 was not driven by FMF-attributed clinical manifes-
tations but by severe manifestation of the associated HSP.
The incidence of HSP in FMF patients is significantly
higher than in the normal population (2). Furthermore,
the occurrence of FMF-associated MEFV mutations is
higher in HSP patients when compared with the general
population (2).
Disease associations of FMF and/or increased carriage
of MEFV mutations have also been reported for a number
of other diseases, eg, polyarteritis nodosa (2), rheumatic
heart disease (23), and Behçet’s diseases (2). Interestingly,
anakinra treatment in a girl with FMF associated with
Behçet’s disease reduced the clinical symptoms of both
diseases (14).
Efficacy and Treatment Modalities
of IL-1 Targeting Drugs in FMF Patients
As case reports are currently the only available source of
information for the evaluation of the efficacy of interleu-
kin-1 targeting drugs in FMF, no reliable conclusions can
be drawn. Treatment with anakinra (1 mg/kg in children
and 100 mg/d in adults) or canakinumab (usual doses
2 mg/kg/8 wk in children under 40 kg and 150 mg/8 wk
in adults) was beneficial to all of the cases published here
and by others, suggesting that interleukin-1 targeting
drugs may be a good option when looking for a treatment
additional to or alternative to colchicine. One should nev-
ertheless bear in mind that off-label treated patients tend
to be reported only when results are positive. Controlled
trials are now necessary to evaluate the tolerance and effi-
cacy of interleukin-1 targeting drugs in FMF patients.
The duration of the treatment depends on the clinical
indication. In some cases anakinra may be necessary only
for a limited time to manage a difficult clinical situation.
In case 6, for example, anakinra was used for 2 weeks to
treat an episode of FMF-associated PFMS. In most
patients, however, interleukin-1 targeting drugs were
used to control the frequency and/or severity of FMF
episodes. This can be done either by using a chronic treat-
ment to prevent attacks or by an acute treatment at the
onset of the attacks. In all patients reported here and most
published cases, anakinra was used as a chronic, daily
treatment. In 1 case, however, anakinra was used punctu-
U. Meinzer et al. 269
6. ally directly after at the onset of the first clinical signs of an
FMF episode (9). The authors report that anakinra re-
duced the severity of the crises during a follow-up of 6
months, suggesting that in patients with good compli-
ance, early treatment at the onset of the attacks may be
considered. In contrast, in case 4 anakinra had no effect
on the severity of FMF episodes when used at the onset of
crises, whereas daily injections induced complete clinical
remission, indicating that daily injections may be more
efficient than treatment of crises only.
Another question is whether colchicine treatment
should be continued or discontinued when introducing
interleukin-1 targeting drugs. In patients with toxic side
effects to normally dosed colchicine, the dose can be ei-
ther reduced or stopped. In case 1, for example, consider-
ing the development of severe neuromyositis, the physi-
cians decided to completely stop colchicine. In all patients
in whom interleukin-1 targeting drugs were introduced
because of insufficient control of the disease activity, col-
chicine treatment was continued. This approach seems to
be safer, given the empirical character of treatment with
IL-1 targeting drugs vs the well-documented beneficial
effect of colchicine, especially in terms of preventing renal
AA amyloidosis.
Safety of Anakinra in FMF and Other Diseases
No reliable data about safety of interleukin-1 targeting
drugs in FMF patients are currently available. In other
diseases, however, including adult rheumatoid arthritis
and juvenile idiopathic arthritis, anakinra has been shown
to be well-tolerated in adults and children (24,25). In the
published FMF cases, local pain and inflammatory signs
at the injection site were the only reported side effects of
anakinra and canacinumab. Even though they tend to be
mild and improve over time, they may cause problems for
compliance or complicate the agreement to injections in
pediatric patients (case 7).
The potential risk of infections is a general concern
when using biotherapies. Serious infection in rheumatoid
arthritis patients treated with anakinra was the subject of
a recent meta-analysis (26). The overall pooled Odds Ra-
tio for serious infections did not show a significantly in-
creased risk. However, the risk was increased for a high
dose of anakinra vs low dose, and high dose vs placebo
(Odds Ratios ϭ 9.63 (95% CI: 1.31-70.91) and 3.40
(95% CI: 1.11-10.46), respectively). When patients with
comorbidity factors were excluded, the results were not
statistically significant whatever dose groups. This analy-
sis indicates a potential risk of serious infections, espe-
cially in patients with comorbidities. The risk of infec-
tions may also be higher in very young children in whom
the immaturity of the immune response is less effective
against polysaccharide encapsulated bacteria (27). By
consequence, from a practical point of view, the existence
of comorbidity factors should be taken into consideration
for the benefit-risk evaluations before treatment. Vaccina-
tion against Streptococcus pneumoniae should be updated
and in very young children antibiotic prophylaxis during
treatment should be considered. Finally, cholesterol and
triglyceride levels and blood cell counts should be moni-
tored.
New Interleukin-1 Inhibitors
In all of the published patients (9-16) and in cases 1, 2,
and 4-7 of this report anakinra was used to target inter-
leukin-1 signaling. A number of other IL-1 inhibitors are
currently in different stages of development, including
the long-acting molecules canakinumab and rilonacept.
Whether long-lasting drugs should be used as a first-line
treatment (case 3), or only after having confirmed the
clinical benefit of silencing the IL-1 pathway with short-
acting drugs, or when compliance problems are encoun-
tered (case 7) needs to be discussed. Long-acting mole-
cules are indeed appealing because of their convenience of
use and may resolve problems with patient compliance.
However, data on safety and tolerance of these drugs are
currently very limited and their long-lasting effect cannot
be interrupted even when adverse effects occur.
CONCLUSIONS
Colchicine treatment is safe and effective in the large ma-
jority of FMF patients. However, the published cases in-
dicate that in some, rare patients the availability of an
alternative treatment would be desirable. The data for the
use of interleukin-1 targeting drugs in FMF patients are
currently limited to uncontrolled off-label use. Alto-
gether, the published cases indicate that interleukin-1 tar-
geting drugs may be good candidates when looking for a
treatment alternative to or supplementary to colchicine.
These observations highlight the need for controlled trials
to further evaluate the safety and efficacy of interleukin-1
antagonists in FMF patients.
