During the lockdown measures put in place at the time of the first wave of the Covid‐19 pandemic in Spain (March through June 2020), LGBTQ+ youth lived through a particularly stressful situation that has so far received little attention. Confined in homes that are often hostile to their sexuality, struggling with the transition to online classes, they reached out to Internet social networks to obtain the support most of them lack in person. This article explores the role of technology for LGBTQ+ youth during a period when the educational environment was not supportive of students' sexuality and identity needs. The research assesses correlations between the use of online social networks and the perceptions of support received from others (using the concepts of social support, thwarted belongingness and burdensomeness, and cohabitation in their homes). The study involves a sample of 445 Spanish participants aged 13 to 21. A descriptive multivariate analysis of variance and bivariate correlations was performed. We found that social networks were very important for LGBTQ+ youth during the pandemic, helping them to explore their identities, but could also be a source of violence. In this regard, while trans and nonbinary youth’s use of social networks to contact acquaintances show important differences when compared to that of gays, lesbians, and bisexuals, the former group also experiences more violence coming from these networks, finds less social support through them, and feels a stronger sense of burdensomeness in relation to them. Additionally, they were often living with people other than family members during the lockdown. This data suggests the need to offer specific support and online services for LGBTQ+ youth, particularly for trans and nonbinary youth.

Since 2012, 16 laws granting rights to trans individuals have been passed in Spanish regions. How can we assess the quality of these laws? Do they all profoundly and positively transform trans people’s well-being? Do they tackle the economic marginalization of trans people? Do they have a symbolic impact? Using multidimensional criteria, I analyze trans-specific and LGBTI+ antidiscrimination policies to define trans-positivity in policymaking. This article uses feminist theory to judge this legislation’s value, contrasting that with the insights of activists and policymakers interviewed for this purpose. Benefiting from the discussion between Nancy Fraser (1995) and Judith Butler (1997), the quality of trans legislation can be assessed by looking at both cultural recognition and economic redistribution. In addition, following Andrea Krizsan and Emanuela Lombardo (2013), I also analyze these laws through the lens of empowerment and transformation. Having made the elusive relationship between sexuality and political economy in trans laws in Spain visible, I call for greater imagination to envisage other sorts of political actions for trans people.

Maximum light-saturated photosynthetic rate (Pmax) and stomatal conductance (gs) of field-grown cocksfoot (Dactylis glomerata L.) leaves in a silvopastoral system were measured at different times under moderate (850–950 µmol m−2 s−1 photosynthetic photon flux density, PPFD) and severe shade (85–95 µmol m−2 s−1 PPFD). Also Pmax and gs were measured after 30, 60 and 180 min of severe shade to determine the lag in the rise of photosynthesis rate from low to high irradiance levels (induction state). The highest Pmax and gs values obtained were 26·5 µmol CO2 m−2 s−1 and 0·41 mol H2O m−2 s−1 in non-limiting conditions with full sunlight (1900 µmol m−2 s−1 PPFD). These values were defined as standardized dimensionless Pmaxs=1 and gss=1 for comparison of treatment effects. The Pmaxs under severe shade decreased by 0·004 units per minute from 1 to 180 min and reached a steady-state of 0·37 units after 140 min. Under moderate shade, Pmaxs decreased by 0·002 units per minute from 1 to 120 min and reached a steady-state of 0·76 units. The time required to reach full induction on return to full sun (Pmaxs=1) was 15 min after 30 min of severe shade and 37 min after 180 min of shade. Mathematical equations were derived to describe the changes in Pmaxs and gss under severe and moderate shade and during induction. The rate of change of gss was slower than for Pmaxs on entering shade and also slower during the subsequent induction process. This indicated other factors in addition to gs were operating in the reduction and increment of Pmax and a two-step model to explain this is proposed. The defined photosynthetic responses of cocksfoot leaves to fluctuating light regimes could be used to develop quantitative predictions of Pmax for inclusion in a canopy photosynthesis model of silvopastoral systems.

A simple multiplicative model using temperature, foliage nitrogen (N) concentration and water status was developed to predict the maximum photosynthetic rate (Pmax) of field-grown cocksfoot (Dactylis glomerata L.) leaves when none, one, two or all the factors were limiting. The highest Pmax was 27·4 μmol CO2 m–2 s−1 in non-limited conditions, which was defined as the standardized Pmax value dimensionless (Pmaxs=1). Pmaxs increased 0·058 units per °C from 10°C to the optimum range (19–23°C) (Pmaxs=1) and then declined 0·077 units of Pmaxs per °C from 23 to 31°C. Pmaxs=1 was also measured from 59 to 52 g N kg−1 dry matter (DM) foliage N. Pmaxs then decreased at the rate of 0·115 units per 10 g N kg−1 DM from 52 to 26 g N kg−1 DM, and 0·409 units of Pmaxs per 10 g N kg−1 DM from 26 to 15 g N kg−1 DM. For predawn leaf water potential (ψlp), Pmaxs=1 was measured from −0·1 to −1·2 bar but declined linearly at a rate of 0·078 units per bar of ψlp from −1·2 to −14·0 bar because of a linear decrease in stomatal conductance. An interaction between low N content (≤20 g N kg−1 DM) and high temperature (〉23°C) was also detected. Together, this multiplicative model accounted for 0·82 of the variation in Pmaxs.

Skin infections caused by dermatophytes are one of the most frequent dermatological complications in patients with acquired immunodeficiency syndrome (AIDS) resulting from infection with human immunodeficiency virus (HIV). Tinea unguium associated with AIDS is characterized by being clinically more aggressive and therapeutically more difficult to treat than in the general population. Terbinafine is considered to be a first-choice option for the treatment of dermatophyte onychomycosis in immunocompetent individuals. This drug has been used in a series of 21 HIV-positive patients diagnosed with tinea unguium for 1 year in the University Hospital La Paz, Madrid. All patients underwent a subsequent clinical follow-up for 6 months. The results showed a high percentage of clinical and mycological cures, as well as maintenance of the response after follow-up; no drug interactions or significant adverse effects related to the drug under study were recorded.

Immunosuppression is a well–documented precipitant of porokeratosis (PK). However, PK is not considered among the most common cutaneous disorders in immunosuppressed patients. We studied prospectively a series of 103 renal transplant patients and found 11 cases (10.68%) of PK. Our series represents the highest incidence of PK in transplant patients reported so far. Our findings suggest that PK in transplant recipients may be more frequent than previously thought.
