Sex and gender considerations in reporting guidelines for health research: a systematic review

Background Despite growing recognition of the importance of sex and gender considerations in health research, they are rarely integrated into research design and reporting. We sought to assess the integration of sex, as a biological attribute, and gender, as a socially constructed identity, in published reporting guidelines. Methods We conducted a systematic review of published reporting guidelines listed on the EQUATOR website (www.equator-nework.org) from inception until December 2018. We selected all reporting guidelines (original and extensions) listed in the EQUATOR library. We used EndNote Citation Software to build a database of the statements of each guideline identified as a "full bibliographic reference" and retrieved the full texts. Reviewers independently extracted the data on use of sex and gender terms from the checklist/abstract/main text of guidelines. Data were analyzed using descriptive statistics and narrative synthesis. Results A total of 407 reporting guidelines were included; they were published between 1995 and 2018. Of the 407 guidelines, 235 (57.7%) mentioned at least one of the sex- and gender-related words. In the checklist of the reporting guidelines (n = 363), “sex” and “gender” were mentioned in 50 (13.8%) and 40 (11%), respectively. Only one reporting guideline met our criteria (nonbinary, appropriate categorization, and non-interchangeability) for correct use of sex and gender concepts. Trends in the use of "sex" and "gender" in the checklists showed that the use of “sex” only started in 2003, while “gender” has been in use since 1996. Conclusions We assessed the integration of sex and gender in reporting guidelines based on the use of sex- and gender-related words. Our findings showed a low use and integration of sex and gender concepts and their incorrect use. Authors of reporting guidelines should reduce this gap for a better use of research knowledge.

Sex and Gender Considerations in Reporting Guidelines of Health Research: A Systematic Review

Background: Despite growing recognition of the importance of sex and gender considerations in health research, they are rarely integrated into research design and reporting. We sought to assess the integration of sex, as a biological attribute and gender as a socially constructed identity in published reporting guidelines. Methods and Findings: We conducted a systematic review of published reporting guidelines listed on the EQUATOR website (www.equator-nework.org) from inception until December 2018. We selected all reporting guidelines (original and extensions) listed on the EQUATOR library. We used EndNote Citation Software to build a database of the statement of each guideline identified as full bibliographic reference and retrieved the full texts. Reviewers independently extracted the data from the checklist/abstract/main text of guidelines. Data were analyzed using descriptive statistics and narrative synthesis. A total of 407 reporting guidelines were included; they were published between 1995 and 2018. Of the 407 guidelines, 159 (39%) mentioned sex and/or gender in the checklist/abstract/main text. Of these, 90 (22.1%) mentioned only sex, and 91 (22.4%) mentioned only gender. In the checklist of the reporting guidelines (n = 363), sex and gender were mentioned in 50 (13.8%) and 39 (10.7%), respectively. Only one reporting guideline met the three criteria of correct use of sex and gender concepts. Trends in the use of sex and gender in the checklists showed that the use of sex only started in 2003, while gender has been used since 1996. Conclusions: We assessed the integration of sex and gender considerations in reporting guidelines based on the use of sex- and gender-related words. Our findings showed a low use and integration of sex and gender concepts in reporting guidelines. Authors of reporting guidelines should reduce this gap for a better use of research knowledge.

Mahasweta Devi’s Rudali: Wailing Motherhood

Mahasweta Devi’s Rudali has gained critical responses for raising the voice on behalf of the silenced subaltern individuals and communities. However, this paper attempts to analyse the text through the gendered lens of ‘motherhood’. Rudali not only delineates the struggles and exploitations of the lower caste people and the outcastes, but the text also divulges the condition of mothers and their struggles of mothering. Mahasweta Devi, true to her strong writing agendas, has not written in favour of the mothers belonging only to the subaltern communities; she has taken into account of those mothers who are wealthy and belong to respected families as well as those who are defamed and disrespected and belong to the marginalized, red-light areas of the society. All the ‘mothers’ portrayed in Rudali have undergone similar ecstasy, agony, humiliation, dejection and rejection. The text leads us through motherhood as a ‘community’ and not just a biological attribute conferred with a namesake social status.

Seasonal Growth, Biomass Allocation, and Invasive Attributes Manifested by Dioscorea bulbifera L. (Air-Potato) Plants Generated from Bulbils in Florida

Dioscorea bulbifera is a serious invader of various ecosystems in Florida, where plants generated by its two morphotypes climb aggressively and smother supporting vegetation. There is a dearth of published research on its invasive biological attributes including vine growth and biomass production by plants generated from bulbils. Herein, we assessed these parameters in common garden studies by planting bulbils from four biomass categories (PBBCs I–IV) of both morphotypes. Vine lengths, longevity-based growth rates (VLGR), biomass, and quantities of leaves and daughter bulbils in both morphotypes showed positive correlation with the biomass of planted parental bulbils. This indicated similarity between corresponding attributes in two morphotypes. Total vine length showed strong positive correlation with VLGR, biomass, and quantities of leaves and bulbils. Overall vine longevity among plants from PBBCs I–IV did not significantly differ whereas the total vine lengths, VLGRs, number of branches, and quantities of leaves and bulbils increased with the biomass of the parental bulbils. Plants recruited by smaller bulbils allocated more biomass to leaves and tubers compared to stems and bulbils, whereas the plants recruited by larger bulbils allocated more biomass to leaves and bulbils compared to tubers and stems. Higher proportion of biomass allocation to leaves and bulbils presumably ensures immediate faster growth, longer vines, and a greater number of daughter bulbils for future recruitment of new plants. Vine length (associated with faster growth rate, capable of blanketing supporting structures and producing large quantities of bulbils) has been noted as the primary invasive biological attribute that facilitates D. bulbifera's status as a noxious exotic weed in Florida. Control measure that can reduce vine length should reduce or eliminate the invasive behavior of D. bulbifera in Florida.

Differential survival among Tahitian tree snails during a mass extinction event: persistence of the rare and fecund

The deliberate introduction of the rosy wolf snail Euglandina rosea to the Society Islands in the 1970s led to the mass extirpation of its rich Partulidae (Pilsbry, 1900) fauna, comprising approximately half of all species in this Pacific island tree snail family. On Tahiti ongoing field surveys have documented the survival of two of seven endemic species of Partula (P. hyalina and/or P. clara) in 38 valleys. E. rosea is now a potent extinction agent across Oceania and determining the factors enabling these two taxa to endure may have wide conservation import. We hypothesized that P. hyalina and P. clara have survived because they were the most abundant and/or widespread species and that they will eventually become extinct. We lack demographic data contemporaneous with predator introduction, but an early 20th century study by H.E. Crampton provides historical demographic data for intact Tahitian partulid populations. Crampton found that P. clara and P. hyalina, although widespread, were consistently rarer than their now-extirpated congeners, including in the 23 valleys he surveyed that retain surviving populations. Given this result, and the recent finding that P. clara and P. hyalina comprise a discrete founding lineage in Tahiti, it is plausible that some shared biological attribute(s) may have contributed to their survival. Crampton recorded the clutch sizes of thousands of gravid Tahitian partulids and found that these two taxa had higher instantaneous mean clutch sizes than did co-occurring congeners. Higher fecundities may have contributed to the survival of P. hyalina and P. clara in the valleys of Tahiti.

14.—Sea-floor Fossils: Keys to Historical Oceanography

If any physical, chemical, or biological attribute of the ocean is examined over an appropriate time scale it is usually possible to document significant fluctuations and to discern in these fluctuations periodic as well as random components. Seasonal variations in current systems, water temperature, salinity, productivity and in the composition of biological communities are familiar examples of quasi-periodic changes commonly studied by oceanographers for the insights they offer into marine processes.
